"OK....OK....," the boy managed to stammer out between helpless giggles, "I....I....surrender!"

"'Bout time, you little sod! I'm knackered!" The teenager's tone was strictly mock-annoyed, though - he'd loved the rough and tumble games that had been a part of his childhood, and now, early youth, for as long as he could remember, games like the tickle fight that had just come to its end, but, above all, he loved his 'little bro', even though that description was becoming less accurate by the day, as his younger sibling moved into the first stirrings of the puberty that he himself had been experiencing for the previous two or three years.

"G...good job....you stopped....Luc," the younger boy panted, "I'd have pissed on you otherwise! Then you'd have won, but lost big time, too!"

"Good job for you, you mean! I'd have killed you if you'd done that!"

"You wouldn't - you'd have enjoyed it, you perv!"

"Ewwww - no way! Pissing on someone, that's really gross!"

"I bet some people do it - from what we've seen on the net, pretty much everything else seems to happen! Anyway, I'm going to pee now - get out of the way, perv!"

Lucas made as if to grab for his brother, but Charlie nimbly skipped around the older boy, pirouetted, and stuck his tongue out playfully.

"Too slow!"

"Are you going indoors, Charlie?"

"Nah, I'll just water the plants instead!"

"Mind the foxes don't take a bite out of your dick - not that it'd be more than a little snack for them if they did!"

"Sod off! I bet I'm bigger than you were at my age!"

14 year old Lucas and his 11 year old brother were taking part in 'Den Day', an event to raise money for a children's charity where youngsters were being sponsored to build a den and sleep in it for a night. Lucas and Charlie had set theirs up in the garden of the family home with help from their dad and Charlie's friend Robin, who was taking part in the event himself, along with his 10 year old sister Cassie. Theirs is indoors, Lucas remembered, lucky them! I hope it doesn't rain. As if on cue, Lucas heard what sounded like the beginning of a shower, but it stopped again within seconds, and the boy realised it was simply Charlie relieving himself a few feet away. The younger boy ducked back into the den with an exaggerated sigh.

"That's better! What time is it, Luc?"

"Half eleven. Are you tired, then?"

"Nah, just wondered. What do you want to do now?" There was, perhaps, just a hint of suggestiveness in Charlie's tone of voice.

Lucas hesitated before answering. It had only been a couple of months earlier, when the family had rented a cottage for a week during the Easter school holidays, that his relationship with Charlie had begun to change - or, more accurately, had begun to develop a new element. The brothers had their own rooms at home, but the little country place only had two bedrooms, so they had needed to share. Early one morning, Lucas had woken with, as many, if not most boys his age did, a raging erection, and after glancing furtively across at his audibly sleeping sibling, he'd decided he had time to deal with it in the immemorial way. As he began to stroke himself, he looked across at Charlie a couple more times, but soon became lost in the pleasure of self-love, and failed to notice the younger boy's eyes open, at first blearily, but, almost immediately, saucer-wide in response to the never-before witnessed spectacle. The crucial moment arrived, accompanied by a groan from Lucas, and a gasp of amazement from Charlie as three spurts of creamy fluid spattered Lucas's stomach. The older boy knew within moments that he'd been 'caught in the act', feeling a surge of anger for a second or two, before admitting to himself that this wasn't Charlie's fault, at all, especially when he noticed that his sibling seemed utterly shocked, and maybe even close to tears. A....are you OK, Luc, Charlie had asked, did you hurt yourself? Lucas had wiped his body clean with his discarded T-shirt from the previous day, pulled his shorts back into place, and moved to put an arm around Charlie's shoulder, trying to reassure him. No, Lucas had said, it didn't hurt, it felt really good. A little question and answer session had ensued, culminating in Charlie shyly lowering his own pyjama trousers and, a couple of minutes later, after following Lucas's instructions, experiencing the dry version of his brother's joy for the first time in his young life. Since then, they'd 'played' together several times, both boys finding that seeing each other 'doing it' was more exciting than practising the art alone. Charlie had shared his new knowledge with his best friend Robin, too, when they'd had a sleepover at Robin's house at the end of the Easter break, Robin immediately becoming as enthusiastic a participant as the brothers. None of the boys, though, had gone any further up to that point, albeit not for the want of trying in Lucas's case - he had a girlfriend, Abby, a year younger than himself, but in spite of his relatively subtle persuasion, she'd refused to do anything beyond allowing a few touches outside of their respective clothing, he exploring her budding breasts, while she tentatively gauged his excitement with the palm of her hand. Lucas knew there was more, though, and wanted more. He'd been exploring online in the run-up to 'Den Day', and, after getting the expected refusal from his parents to his proposal for Abby to spend the night in the den, he'd decided that tonight was going to be the night that 'more' was going to happen. And if that meant sharing new things with Charlie, sobeit.

"Luc?" Lucas was brought back to the here and now.

"Yeah?"

"You wanna....play?"

Lucas felt a surge of excitement in his stomach, rapidly followed by another sort of surge, a little lower down. "I....if you want, y....yeah." Maybe this would be easier than he thought - Charlie initiating certainly lowered Lucas's sense of embarrassed trepidation.

"You don't think....Mum and Dad will come out and check on us, do you?"

"I doubt it, Charlie - if they were going to, they'd have done it by now, I reckon."

"S....shall we get....naked, then? I bet that would make it....even sexier!"

Wow, Lucas thought, my little bro is getting brave! "O....OK, then. Just keep your blanket close to you, though, then if they do come out, we can cover up quickly.Where did you get the idea to get naked, anyway?"

Even in the dim light of the camping lamp, Lucas saw Charlie blush. "W....well....I....saw Rob....undressed when we had our last sleepover, a....and I....liked it! His is huge, Luc, the same size as yours, I'm not joking, just a bit skinnier! He says his dad has got a massive one, he's seen his dad in the bathroom, at swimming, and stuff, and it runs in the family! I....I mean, I'm not....gay, or anything, at least, I don't think so, I like girls, a lot, but it really was amazing seeing Rob!"

Lucas, despite his not thinking of himself as anything but straight, found himself shuddering involuntarily at the mental picture his brother's description had conjured up - Robin was a very handsome little guy, and the idea of him having plenty to brag about between his legs, too, was unexpectedly, but powerfully, erotic to the teen. I'd love to see that, he thought, almost in spite of himself, as even more blood seemed to pump into his throbbing erection.

"I....it wouldn't matter to me if you were....gay, Charlie. You're my bro, and I....love you, no matter what!"

"I....I love you too, Luc, you're the best!" Charlie's voice dropped, almost to a whisper. "C....can I....come over, and....lie....next to you....please?"

"C....course you can, Charlie. Don't forget your blanket, though!"

The younger boy quickly shucked off his clothes, and laid down close to his brother, sighing happily.

"You gonna get undressed too, Luc?"

"Y....yeah. Give me a minute."

For a few moments, Lucas had second, then third thoughts - wasn't this wrong, somehow, we're brothers - but then Charlie rolled onto his side, rolled a little closer, close enough to touch Lucas's bare arm and leg. The older boy felt the dry warmth of his brother's silky skin, and couldn't help but love the feeling. And there was something else, too - Charlie's rock hard little erection pressing into his shorts-clad thigh. Lucas's penis bucked at the sensation, and his last inhibitions melted away. In seconds, he was as bare as his sibling. The boys laid face to face, admiring each others' lithe young bodies. Now, Lucas, thought, now something really is going to happen. He didn't have long to wait.

"Luc....c....can I....touch y....yours? Y....your dick. Please? I want to see what it....feels like."

Lucas's heart seemed to be beating its way out of his chest. "I....if I can....touch yours, too," he heard himself say, almost as though the words had come from outside of himself.

"Oh, y....yeah," Charlie breathed, "th....that would be great!"

The two boys reached out, Lucas with his left hand, Charlie with his right. First contact was almost simultaneous, as were the gasps of pleasure from each brother. As if telepathically synchronised, the two hands began to stroke, gently, slowly.

"Ooohhh, Luc! Th....that feels....awesome! Do it more!"

"Y....you're doing....great, too! Don't stop!"

For both boys, their first direct sexual contact with another person was breathlessly exhilarating, and both were soon panting at the thrilling feelings. Charlie was the first to feel his body shivering out of control.

"Uh....uh....getting....my....cum....right....NOW!" Lucas's fingers registered the sensation of his brother's penis tensing, stiffening still further, then launching into a series of powerful dry spasms. Charlie stopped actively masturbating his brother, but his grip tightened on Lucas's almost painful erection, more than enough to tip the older boy over the precipice of ecstasy.

"Nnnggghhh! Ooohhh....shiiiiit!" Lucas's body simply erupted into the most spectacular orgasm of his life, five, six gushes of his nearly mature semen spraying himself, his brother and the bedding between them. Charlie's own orgasm was still going strong - how the hell can he still be cumming, Lucas marvelled, even in the throes of his own delight - so it took long seconds before the younger boy's senses finally calmed enough for him to be able to react to the wetness on his hand and arm.

"Ewwww!! You've cummed all over me, Luc! It's everywhere!"

"S....sorry....Charlie, I....couldn't....help....it, " Lucas gasped out."That's the....biggest....one I've....ever had! I didn't....even know....I could....cum that....much! I....I've got a towel here, a clean one, use that to wipe it off."

Charlie's attention had turned elsewhere, though, as he looked in what seemed like fascination at the pearlescent fluid coating his fingers. He raised his hand towards his face, and sniffed curiously.

"Smells like swimming pools, sort of. I'll make....cum soon, won't I?"

"Yeah, a year, probably, two at the most. It'll be sort of watery at first, though - at least, mine was - and not that much. But it gets whiter, and you make more, as you get older."

"Does it....taste of anything?"

Lucas opened his mouth to answer, then stopped himself. If I tell him, he'll know I've tried it, the teen thought. He might freak out! But, then again, he might just....do what I want to....try next.

"N....not much. It's just sort of....gooey. It's not like....anything else I can think of."

Charlie sniffed at his hand again, then, to Lucas's amazement, stuck his tongue out and tentatively licked at his skin. His nose wrinkled a little, but it didn't stop the younger boy repeating the dose, with a larger sample.

"I....it's OK, doesn't taste of much, like you said. Pass me the towel, though, I don't think I want all of it!"

Lucas did as he'd been asked, before taking the towel back and cleaning himself, and as far as he could, the bedding, as well. Charlie grinned happily.

"That's better! You know you said....you had your....biggest one ever?" Lucas nodded. "I....I did, as well. Actually, I think I had two, one straight after the other. That's never happened to me before. Do you think it was better because we did it to each other, instead of just doing ourselves?"

"Maybe. I heard someone at school saying he liked his girlfriend ....wanking him a lot more than when he did himself. Lucky bugger! And some of that stuff we've seen on the web - they look like they're having huge ones, all the time!" Charlie giggled at the memory of their furtive online investigations, and his hairless penis began to rise once more.

"You know what I think looks like it would be....really hot?" Lucas asked.

"What?"

"G....getting your....dick....sucked. I get....really horny when I see....girls doing that to guys!"

"Guys do it to other guys, too...." Charlie blurted out, before stopping abruptly, his face instantly burning up with embarrassment, his eyes averted, as he realised that Lucas now knew he'd looked at....gay stuff online. Lucas didn't laugh or tease, though. Instead, he looked calmly at his little brother, and answered quietly.

"I know - I....I've....seen it, too." Charlie looked up, wide-eyed. "Charlie - if....you want to....I wouldn't....mind....doing it to you. If you've washed it, that is!"

"R....really?! Y....you'd really....suck my....dick?"

"If it's clean, yeah. Really."

"Y....yeah, it is - clean, I mean. Dad told me about washing under the extra skin ages ago, he said it can get smelly, or even infected, if you don't. So I do it every time I have a shower."

Lucas knew that his brother showered virtually every day, and had also had the same conversation with their father, a few years earlier, leaving him in little doubt about Charlie's cleanliness. OK then, he thought, let's go for it. He shuffled to his right, guiding Charlie onto his back in the centre of the mattress, before gently parting the younger boy's legs and kneeling between them. The siblings' eyes met, Charlie looking uncertain until his brother smiled warmly.

"Don't worry, Choo," Lucas whispered, "I won't hurt you, I promise." Charlie's heart almost melted at his beloved brother's use of his 'baby' nickname, a rare occurrence these days, smiling delightedly in response.

"I know you won't, Luc! I'm so excited!"

As if in confirmation, Charlie's erection twitched visibly, once, twice. Lucas shivered at the thought of the younger boy being so aroused, so eager. He slowly lowered his head, then, once within range, flicked the tip of his tongue across Charlie's partially exposed glans. The younger boy's whole body seemed to spasm as the new sensation shot through him.

"Ooohhh, Luc, oh God! Again, please!"

Lucas, in turn, shivered at the feeling of his brother's rigidly erect penis against his tongue, tasting faintly salty, but otherwise little different from licking a clean finger. After maybe a dozen, increasingly firmer, strokes, he lowered his head a little more, and gently took the throbbing flesh between his lips, his tongue still busy. Charlie groaned in ecstasy as Lucas, remembering videos seen online, began to bob his head slowly while applying a little suction. There was no way the younger boy could hold out against that degree of stimulation, squealing as his orgasm hit like a flash flood. Lucas moaned in turn as he felt Charlie's little spike pulse again and again against his tongue and palate. It was over all too soon, for both boys, as Charlie instinctively pulled free from his brother's oral caresses, the sensitivity too much to contend with. He laid back breathing heavily for long seconds, before looking up at Lucas, a huge grin on his flushed face.

"Wooooow! That was sooo awesome, Luc! I thought my dick was going to melt, or something!"

Lucas beamed in return. "Glad you liked it!" There was a hiatus, the feeling of an unspoken question between the siblings. The smiles were replaced by an air of seriousness. Lucas continued, hesitantly. "Ch....Charlie? W....would you....do me? P....please?"

There was a momentary look of what might almost have been panic in the younger boy's eyes, but he liked to 'play fair' - Lucas had given him probably the best feeling of his life, how could he refuse to reciprocate. Charlie swallowed, visibly.

"I....I'll....try, Luc. I....I don't really....know how, though."

"Just do....what I did. Keep your teeth....covered up, and just....you know, lick and suck it."

"How can I cover my teeth up? What with?"

"Your lips. Here, give me one of your fingers, and I'll show you."

Charlie held his hand out, and Lucas demonstrated the technique, causing his sibling to giggle.

"Try on my finger now, Charlie, see if you've got it!"

Charlie tentatively took Lucas's forefinger into his mouth for a few seconds.

"Like that?"

Lucas shivered, both at the sensual feeling of Charlie's lips against his skin, and the knowledge of what might be replacing that finger in the youngster's mouth any minute.

"Yeah, just like that. Don't try and put it all the way in, though, you might choke." Charlie looked at his brother's erection, and licked his lips nervously. The organ suddenly seemed to be twice the size it was before.

"L....Luc? W....will you....tell me before you....cum? I don't know if I want it....in my mouth."

"Course I will, Choo. I won't make you do anything you don't want to, promise."

"O....OK, then. Are you going to....lie down?"

Lucas nodded, and rolled onto his back. Charlie knelt between his splayed thighs, still looking very uncertain. Lucas smiled once more, reassuringly, he hoped, but his own excitement and nervousness meant that a neutral observer might have seen his expression as a sheepish grin. Charlie took a deep breath, and moved his lips towards his brother's visibly throbbing penis, the foreskin almost completely retracted. He stopped a few centimetres short, and sniffed. Doesn't smell bad, Charlie thought, just a faint remnant of the odour of the semen from Lucas's earlier orgasm. Very slowly, he moved closer still, just millimetres away now, then....he kissed the glistening flesh gently. Lucas gasped as a wave of pleasure raced through his groin.

"Oh, Charlie," he whispered, "do that again!"

Charlie smiled, mostly to himself, and did as Lucas had asked, this time allowing his tongue to poke beyond his lips, taking his first taste of his brother's penis. Little more than salt, with a slightly sweet overtone. It's nice, the younger boy thought, I didn't think it would taste nice at all. He licked again, more confidently. Lucas's reaction was immediate, as he shuddered and moaned. Charlie smiled again, happy to be giving the same sort of pleasure he'd so recently received, before setting about his task with renewed enthusiasm, lapping at his brother's corona before moving higher, to the leaking slit at the apex. His reward was another stripe of sweetness against his tongue, as Lucas's precum began to leak freely. Charlie parted his thin lips, wrapping them around the spongy head of Lucas's erection.

"Ooohhh yessss! So good, Choo, feels so good!"

Charlie remembered how Lucas had moved his lips up and down, and imitated his brother's actions, albeit only taking the glans and two or three centimetres of shaft into his mouth on the downstroke. That was more than enough to send Lucas straight to boy heaven, though, and it was only seconds before he was gasping out his warning.

"Gonna cum, Choo, gonna cum....right now!"

Charlie heard the words, but barely registered their meaning, until he felt the first spurt of warm fluid race across his tongue. Rather than pulling away, he sucked harder, making Lucas whimper as three more huge muscle contractions shot through his genitals. Charlie, needless to say, had no idea what to do about the salty liquid in his mouth, so instinctively swallowed, causing his brother to writhe and groan at the pleasure, more pleasure than he'd ever known. Charlie seemed to be in a trance, sucking and sucking, swallowing the last droplets of his brother's ejaculation, but still going, seemingly insatiable. It was far too intense for Lucas to bear, though.

"Stop, Choo, please stop! It....it's too much!"

Lucas's penis left his brother's mouth with an audible 'pop', the older boy literally shaking in the aftermath of his pleasure. Charlie, though, looked as though he might cry.

"S....sorry, Luc! I didn't mean to hurt you. Sorry!"

Lucas sat up, immediately wrapping his arms around Charlie.

"Y....you didn't hurt me, Choo, no way! It was awesome! It just got....too sensitive at the end. Too good, not bad!"

"A....are you sure, Luc?"

"Really, really sure! I'd love you to do it again, any time - if you want to, that is."

The smile returned to Charlie's face. "If you do me, too! I didn't mind, even when you....cummed in my mouth. It didn't taste bad, or anything." There was a pause. "Luc....have you seen any videos where two guys....do it to each other....at the same time? That looks like it could be....really fun."

Lucas's wilting penis rapidly firmed up again at the thought that his brother's words had brought to mind. "Y....yeah, I've....seen that. They call it a '69', I think. You're right, it does look like fun. D....do you want....to t....try?"

"Right now?"

"Why not, I'm hard again, and so are you, by the looks of it!"

"OK!"

And the brothers duly did, twice, in fact, Charlie's non-sperming status giving him the advantage that he was able to have three orgasms to his brother's two, albeit Lucas's last was virtually dry, his younger sibling almost completely depleting his resources. At length, the boys sleepily pulled their nightclothes back on, before snuggling together on Lucas's bed and falling almost immediately into a deep slumber born of happy satiation.

It was almost 9:00 before the brothers stirred, Charlie waking first, to the feel of Lucas's teenage morning erection pressing into his body. He smiled wearily, and pushed himself back against the stiffness, waking Lucas in turn. The older boy gently ran his fingers through Charlie's hair.

"You OK, Choo?"

"Mmmm, yeah. I love snuggling with you, we haven't done it since I was little."

"Yeah, I really like it, too. We'll have to try and do it more often, won't we?" Charlie nodded, smilingly. "A....are you....alright with....the stuff we did last night, Charlie?" Lucas whispered.

"Course! It was really, really fun! Did you like it as much as I did?"

"Y....yeah. I mean, I still really like Abby, and I'd like to do....stuff with her, but if we could....do it....again, some time, that would be....really great!"

Charlie turned to face his brother, looked into his eyes. Then, almost in slow motion, it seemed to Lucas, the younger boy leaned forwards and kissed him gently on the lips.

"Whenever we can, Luc, it was amazing! Hey, Luc, I've got an idea!"

"What?"

"I'm going to ask Mum and Dad if Robin can come for a sleepover next weekend. We might be able to sleep out here again, and....maybe he might like to....play, too. I mean, we've....wanked in front of each other, I....taught him how to do it, so he knows that much, at least!"

Lucas shivered. "Yeah, do that! If he wants to....do stuff, I would, too."

Charlie grinned mischievously. "Let's do a quick 69 now, I'm horny!"

Lucas thought, just for a moment, about the consequences of their parents catching them in the act, but teenage hormones were always going to win out.

"Quick, then! Just in case Mum and Dad come and look for us!"

****

"It's on, Luc!" Charlie told his brother excitedly as they arrived home from their respective schools on Tuesday afternoon. "Robin's coming over on Friday! His parents said it was OK, his mum spoke to Mum last night, he said. And Dad said we can leave the den up until then, too!"

"Great! He knows I'll be here, doesn't he?"

"Yeah, he's fine with it, he likes you! This is going to be great!"

Lucas couldn't help but think about the possibilities for sexy fun, not just with his beloved brother, but with the really cute Robin. He wouldn't have thought of his sibling's best friend in that way before the night in the den, but Charlie had woken something inside him that couldn't be denied - he liked girls, he loved girls, especially Abby, but he was beginning to like boys almost as much. Maybe I'm - what do they call it? - bi, that's it, Lucas thought. The front of his school trousers rapidly tented outwards. Charlie couldn't possibly miss such an obvious sign, and giggled.

"Can't wait, eh, Luc? I'll....help you with that, if you want!"

Lucas grinned sheepishly, and the boys quickly slipped into his bedroom, locking the door behind them.

****

"We're going to sleep outside, in the den, Rob! Dad said the weather forecast is good for this weekend, it should be dry and not too cold. It'll be really fun!" Charlie grinned.

"Yeah! That's brilliant! That won't be till later, though, will it? What else are we going to do?"

"Mum and Dad are going to take us out for pizza. You do like pizza, don't you?" Robin nodded. "Abby's coming, too, Mum told Lucas he could invite her, and her parents said she could go, so Luc's happy! She's alright, she's funny - and pretty hot, too! Not as hot as Amber, though!"

"Why don't you ask Amber to go out with you, Charlie? She's not as....I don't know, quiet, I guess....as you'd think, once you get her away from her mum. We had....fun on Den Day, all three of us." Robin wasn't aware, but his face had flushed a little. Charlie noticed.

"Oh yeah, what sort of fun? I thought you said you didn't snog her!"

"I....I didn't, honest! Anyway, like I said, you should ask her out! You really fancy her, don't you?!"

It was Charlie's turn to blush. "I don't!"

"Oh, come on, you're always on about her! Tell you what, if her mum lets her come over to ours again, I'll tell you, and you can come, too. Get to know her properly, at least. I didn't really know her that well until last week, even though he's been Cassie's best friend for years. She is fun, really!"

"M....maybe. Anyway, Luc will be back from school soon, so we can get changed in my room, then we'll go to Abby's and pick her up, and meet up with Mum and Dad at that new pizza place near Sainsbury's. It's supposed to be really good, Dad says."

The evening was a great success - the food, as advertised, was excellent, the four youngsters got along well - Abby was funny, and pretty, Robin had to agree, though, as ever, she wasn't a patch on Cassie, as far as he was concerned - Lucas enjoyed holding his girlfriend's hand, and even gave her a goodnight kiss, right in front of the younger boys, without the slightest embarrassment, Robin and Charlie smirking a little, but trying, successfully, not to say anything that might have had them accused of being 'childish'. Finally, as dusk fell, and after changing once more in the brothers' respective bedrooms, the three boys made their way out into the family garden, armed with copious amounts of snacks and drinks, ducking into the den just after 9:00.

After an hour or so of games, mostly boyish rough and tumble between the brothers, the three occupants of the den sat on their respective bedding, and began to talk. It wasn't long before Charlie steered the conversation in a predictable direction.

"Remember I said Luc had showed me something new last week, Rob?" Robin nodded. "Do you want to know what it was?"

"Y....yeah, I guess so."

"Have you heard of blowjobs?"

"I've sort of....heard the word, but I don't....really know what it means," Robin admitted, hesitantly.

"I didn't, either, until Luc and I found some....videos online. What it is, is when a girl, or....or a guy....sucks a guy's dick, to give him the....cum feelings, instead of doing it....with your hand, like I showed you before."

Robin's face scrunched, instinctively, into a picture of disgust. "Putting a....dick in your mouth?! That's gross!"

"No, it isn't, Rob, really," Lucas intervened. "As long as the person getting sucked has washed his dick, it isn't any different from putting a finger in your mouth. And it feels fantastic, much better than....wanking!"

"W....what, has Abby done it to you, then?"

There was a momentary hiatus, before Charlie answered, quietly, on his brother's behalf. "N....no, Rob - I did it for Luc. And he did me, too. We even did it to each other at the same time! It's.... really great. Doing it, and having it done, I....I like....both."

Robin looked at the brothers in astonishment. "A....are you guys....gay, or....or something, then?"

"I....I don't think I am," Lucas replied, "but I think I might be....bi."

"What does that mean?" Robin asked confusedly.

"I....it means you like doing....sex stuff with girls a....and boys."

"And I don't know about me at all," Charlie added, "about being gay, or whatever, I mean. I just know it feels brilliant, like Luc said. Something feels that good, I don't even care whether it's a boy or a girl doing it. I just want to do it, as much as I can!"

Robin certainly knew about the intense pleasures that sex with another person could bring, after losing his virginity to his sister and her best friend the weekend before, but doing stuff with another boy? Could that be just as good?

Charlie spoke again, even more quietly than before, little more than a whisper. "D....do you want to....find out w....what it's like, Rob? I'll show you, i....if you like. I'll do you, but you d....don't have to do me, if you don't....want to."

"The same goes for me, too, Rob," Lucas added. "I'd love to try and make you feel good, as well, but, like I said to Charlie last week, I'd never try and make you do anything you didn't want to. Sex is supposed to be fun, it wouldn't be fun if you didn't like what was happening."

Robin's head was spinning at the totally unexpected turn of events, but his body was responding regardless. His penis was so hard, it was almost painful, He swallowed nervously.

"I....I d....don't know....."

Charlie gently touched the front of his best friend's shorts, gauging the arousal he knew would be there.

"Sh....shall we, Rob? I'll stop if you don't like it, I promise."

"Y...you won't....bite me....down there....will you?"

"No way, Rob! Luc showed me how to do it without your teeth getting in the way!"

"O....OK, then. B....but stop if I say, yeah?"

"Course! You're my best friend, I'd never hurt you on purpose!"

Robin tried to smile, but was simply too nervous. Charlie shuffled across beside his friend, hooking his thumbs into the waistband of Robin's shorts and underwear. He carefully slid the clothing downwards, lifting the front of the material to avoid trapping Robin's erection. Lucas's eyes went wide as he saw what was revealed by his brother's actions.

"Wow! Bloody hell, Rob, Charlie said you had a big one, and he wasn't lying! It looks really great!"

Robin did grin this time, proud that he could impress even an older guy like Lucas, the bigger boy quickly moving to the opposite side of Robin's body to his brother.

"I'd love to play, too, Rob! Can I, please? Can we do you both together?!"

Robin seemed to have been robbed of the power of speech by a breathless wave of excitement, but nodded his head, eagerly. The nod was followed almost immediately by a huge gasp, as two hands, one from either side, gently took hold of his throbbing flesh.

"Rob, you're so hard!" Lucas murmured, almost to himself. "A....and your dick is so....beautiful, much nicer than mine!" Robin simply had no words to reply to such a compliment, so merely laid back and luxuriated in the pleasure the siblings were beginning to generate in his young body. Lucas continued to gently squeeze the diamond-hard shaft, while Charlie's nimble fingers fluttered around the glans, carefully moving Robin's tightish foreskin a few millimetres back and forth with each pass. Robin's eyes closed momentarily, but snapped open again as he felt the warm dampness of breath across his boyhood. Charlie's lips approached, slowly, slowly. Robin unconsciously held his breath in anticipation, before jerking and gasping as his friend gently kissed his engorged flesh, before opening his mouth slightly and taking the partly exposed glans inside. Robin shuddered again as he felt Charlie's tongue begin to caress his penis. Hardly had he begun to register the delicious feelings when he started again, as another tongue carefully brushed across his tight scrotum, lapping delicately at the smooth little sac.

"Ooohhh, Luc, Charlie, that f....feels....soooo good. D....don't s....stop, please don't stop!" The brothers slowly increased the intensity of their stimulation, moving faster, licking more firmly, then Charlie began to actually suck on Robin's erection while continuing to slide his tongue across the almost over-stimulated flesh. Robin squealed as his orgasm hit seemingly without any warning, his penis bucking wildly in his friend's oral embrace for long seconds, the pleasure almost too much to bear. Then, as always, it came to an end all too soon, Robin pulling his still twitching penis from between his friend's lips, his body limp, his lungs gasping for breath.

"Oh....wow....that....was....amazing!"

Charlie grinned mischievously. "Told you, Rob! Wanna watch me and Luc do each other? It's called a '69' when you do that."

Robin nodded eagerly, watching enraptured as the siblings adjusted their positions before sucking and licking each other with the greatest enthusiasm. In very short order, it was clear that the show wasn't going to last long, as both boys began to writhe and pant. Robin didn't want to interrupt their pleasure, but his curiosity was overwhelming.

"C....can I watch you....squirt, Luc, please? I....I've never....seen that before."

Lucas pulled away from his brother momentarily. "Yeah, sure, Rob - Charlie, I'll tell you when, and you can finish me off with your hand, OK?"

Charlie didn't miss a beat on his ministrations, simply giving a thumbs up. Within a minute, the climactic moment arrived.

"Now, Choo, now, here it comes!"

Charlie quickly withdrew, grabbing his brother's glistening member, stroking rapidly. Lucas groaned, deeply, as a streamer of creamy fluid leapt twenty centimetres or more into the air, followed by four more spurts of lesser intensity, pattering down onto the teenager's torso and genitals, and his brother's working hand. Knowing Lucas's preferences, Charlie continued to move his hand slowly and lightly, barely touching his brother's exquisitely sensitive flesh, until the older boy sighed and smiled, an obvious 'Thank you, that's enough' message. Robin was simply speechless, for what seemed like hours, but was probably no more than twenty seconds. When he did regain his voice, though, the amazement, the questions tumbled out. Wow, wow, wow, awesome, when will I be able to do that, what does it feel like, what happens if you squirt in someone's mouth? Lucas did his best, while still in the throes of full-on post-orgasmic afterglow, to answer Robin's queries coherently. With an almost cartoonish double-take, Robin suddenly realised something.

"Charlie, you didn't get your....cum, did you?" Charlie shook his head. "C....can I....try....on you? Suck you, I mean?"

Charlie grinned once more, almost fit to bust. "Wow, yes please, Rob, that would be fantastic! You know what to do?"

"Y....yeah, I think so. Tell me if I do it wrong, won't you?"

"Course!"

As Robin began to move towards his best friend, Lucas put a gentle hand on his shoulder and stopped him for a moment.

"Rob....I think you're....really hot, and I love....your dick. Can I....suck you, while you suck Charlie, please?" Robin had never thought of such a possibility, but it didn't take him long to come to the predictable decision.

"Oh, yeah - yeah, course you can, if you want!" Robin felt another stab of curiosity. "W....why do you....like my....dick so much? I mean, it's just like yours, isn't it?"

"I....I don't really know why, properly - it just looks....beautiful to me. It's so long, and straight, a....and I like how it's so pale, you can see the veins under the skin. And how it gets....mega-hard. I mean, I like Charlie's, too, lots - " Lucas glanced over at his brother, smiling lovingly, the younger boy responding in kind, " - but yours is just....perfect, somehow. I can't explain it better than that, sorry."

"Luc's right, Rob," Charlie added. "I've only seen yours and his in real life, but we've seen plenty of others online, and none of them are close to looking as nice as yours! You're so lucky!"

Robin could do no more than grin goofily, before his mouth shot into an 'O' of startled pleasure as Lucas took him gently in hand.

"Let's do it, Rob," Lucas breathed, "all three of us!"

"Let's get in a circle, Luc," Charlie said. "I'll do you again, too, if you want, that is!"

Lucas, just for a moment, gave his brother a classic 'Duh!' look. "What do you reckon?! Course I want!" Charlie and Robin both giggled boyishly as they juggled themselves into the best positions, Lucas moving in turn to form the bottom bar of the triangle. There was no more talk, just muffled moans and whimpers of delight as the three boys luxuriated in the sights, tastes, smells and, above all, the wonderful feelings as they coaxed each other towards their respective peaks. Charlie, not having orgasmed earlier, was the first to go over the brink, but Robin hardly realised, his body awash with the pleasure Lucas's more experienced mouth was engendering, continuing to lick and suck despite Charlie's yelps, soon bringing his best friend to a second climax just as Lucas induced the same ecstasy in Robin's heaving young body. Lucas himself was only moments behind, a powerful, if almost dry orgasm bursting onto his brother's busy tongue. The erotic fires quenched for the moment, the three boys wearily donned their nightclothes before snuggling together, murmuring for a few moments about how great it had been, and how they had to do it again, soon, before sleep overtook them.

****

Robin woke first, daylight already well established as he blinked blearily. He could feel a bigger body close behind him, and didn't take long to realise that Lucas had ended up in the middle of the threesome at some point during the night. Robin began to smirk as he realised that he could feel something else, too - Lucas's morning erection pressing into his buttocks. He wriggled slightly, and it was only a matter of seconds before the older boy stirred, sighing into Robin's ear.

"Hi, cutie! You keep shaking your bum like that, and I'll cum all over it!"

Robin grinned over his shoulder. "You can if you want! It was so hot seeing you squirt last night!" he whispered.

"You wanna see it again? Maybe help me a bit?"

"Y....yeah, I'd love to! What about Charlie, though?"

"He'll be asleep for hours yet, he could sleep through a train crash!"

Robin grinned, turned over, and reached out to touch the prominent bulge in Lucas's shorts.

"C....can I....rub you, make it happen?" Lucas unconsciously licked his lips in anticipation, before nodding mutely. Robin tugged at the waistband of Lucas's lower garment, quickly, with some help from its owner, exposing the teenager's throbbing erection.

"How should I do it, Luc? What feels the best for you?"

"H....hold it just under the....head, and slide the skin backwards and forwards, please."

Robin took the penis in his hand, and tried a few tentative strokes.

"Like that?"

"Yeah, feels really good. Just hold it a tiny bit tighter, and go a bit faster. Yeah, that's perfect, Rob, keep doing it like that!"

It wasn't long before Lucas's teenage body shivered out of control, the boy moaning as his recharged stock of semen blasted out into the cool morning air within a matter of minutes. Robin grinned proudly at his achievement.

"Did I do it right, Luc? Did it feel good?"

"Oh yeah, cutie, it was awesome! Let me do you now, I really want to!"

Robin shucked off his pyjama bottoms almost instantaneously, Lucas quickly getting to work on the rigid boyhood. Lucas was unsure about how clean Robin would be after a night's sleep, but when he leaned forward to sniff, there was nothing but the sweet muskiness of a nearly pubescent boy, slightly more intense than the night before, but, if anything, even more powerfully erotic, so, without further hesitation, Lucas took Robin into his mouth once more. Robin groaned, instinctively thrusting his hips forward, drawing back, then thrusting again, as he'd learned with the girls the previous weekend. Soon, all Lucas had to do was to keep his head still and slide his tongue over the boy's glans as Robin brought himself to the brink.

"Ooohhh, Luc, ooohhh! I....I'm c....cumming!"

And he did, long and hard, a dozen or more pulses dancing against the teenager's tongue before it became too much, and Robin had to withdraw, tears in his eyes.

"Oh, Luc, that was one of the best ones I've ever had! Nearly as good as when I did it with Ca...." The boy's words stopped abruptly, and all the blood seemed to drain from his face. Shit, shit, shit, he thought, what have I done.

Lucas didn't seem to register Robin's words, or his reaction, immediately, but it was very quickly obvious to him that something was badly wrong, the younger boy looking ready to cry. Then, almost audibly, what Robin had said clicked together.

"Y....you mean....you and Cassie....have done....stuff?"

Robin's emotions overwhelmed him, and he burst into tears.

"Don't tell, Luc, please don't tell!" the boy sobbed. "They'll....take me away, I'll never....see Cassie....again!"

Lucas instinctively wrapped Robin up in a close hug, whispering directly into his ear.

"Ssshhh, ssshhh, Rob, I won't, trust me. Don't cry, please."

It seemed to take an age, but Robin finally began to calm down, the genuine warmth of the older boy's embrace helping to convince him that maybe it wasn't the end of the world, after all,

"S....sorry, L....Luc. You must think I'm....a baby."

"Course I don't, Rob. I sort of know why you got so upset - I....I mean, I'm....doing stuff with Charlie, and he's my brother. If we got caught....well, I don't even want to....think about it."

"I won't tell anyone, Luc, I promise. I'm going to have to talk to Cassie, though, tell her....someone else knows about us."

"Is it just me who knows?" Lucas asked.

There was a long silence. "N....no," Robin whispered. "Amber knows, she....caught Cassie and I....doing it. She won't say anything, though, because...." Robin hesitated again, before swallowing, visibly. "Because....I did it with her, too."

'Doing it', Lucas thought in wonderment. Did Robin really mean what the teenager thought he meant. He couldn't resist his curiosity.

"You....you mean....you actually....shagged them? Both of them?"

Robin, despite looking like he might cry once more, eventually nodded his head slowly, then saw, to his amazement, Lucas's face break into a huge grin.

"You lucky sod! They're both soooo hot!" The teen suddenly looked a lot more serious, though. "Y....you'll need to be careful, though, Rob - I know you're not making sperm yet, but with how....big you are, I bet it'll happen really soon. You don't want to get them pregnant."

"I....I know. I'm not going to....do it with Amber again, anyway, we just did it because....she wanted to know....what it was like. But I....really love Cassie, even if she is my sister, and she wants to....do it more, a....and so do I." Despite the distress Robin had been feeling in the previous few minutes, the thought of the intimacy he'd shared with his wonderful sister, and the closeness of the warm body of the older boy, caused his penis to rapidly stiffen once more. Lucas felt the reaction against his body, and grinned anew.

"Bloody hell, Rob, you're a horny little stud! Wanna suck each other again?!"

Robin's sparkling smile was all the answer Lucas needed.

****

Later that morning, Robin was dropped back at home by his friends' father, and, within moments, he and Cassie were sharing a warm, if brief hug outside the girl's bedroom door. Robin took half a step back, and looked his sister in the eye, the expression on his face grabbing her attention at once.

"We need to talk, Cass, as soon as we can. I'll ask Mum and Dad if we can go out on our bikes after lunch. We can go to the park, it should be pretty quiet."

"O....OK, Robbie. W....what's....happened?"

"I....I don't want to talk about it here, in case Mum or Dad hear. Don't worry for now, though, nothing bad's going to happen. At least, I don't think so. I'll tell you later, I promise."

A couple of hours or so after their conversation at home, brother and sister were wheeling their bikes to a bench in their local park, having pedalled through the quiet suburban streets from their nearby home. They took off their cycling helmets, and sat facing each other silently for a moment or two. Robin screwed up his courage, and spoke.

"Lucas knows. About us, I mean."

Cassie looked much as Robin had felt that morning, like she'd just been told the world was about to end. "H....how....?"

"I....it was my fault, Cass. Luc and Charlie and I did....some sex stuff last night - I'd never thought about doing anything with a boy, but it was really fun. Anyway, this morning, Charlie was still asleep, so Luc and I....did more. H....he made me....cum with his....mouth, it felt so awesome, and, before I could stop myself, I said that it was nearly as good as when I did it with you. I knew I'd messed everything up, straight away, and it made me cry, but Luc was really kind, he gave me a big hug and said not to worry, he wouldn't tell, and that he knew why I was so upset, because he does stuff with his brother, too, and wouldn't want anyone to find out."

"D....do you think he'll....keep it a secret, Robbie?"

Robin nodded decisively. "Yeah, I really think so. even Charlie doesn't know. W....we'll have to be really careful in future, though, Cass. I....I mean....I still really want us to do more stuff, y....you're the....best, the sexiest person I know, and I really, really love you, but, if we get....caught...."

"I really love you, too, Robbie," the girl said, smiling sweetly.

"There's....something else we need to be really careful about, too. Luc said he thinks I'll be making....sperms really soon. We can't....make a baby, that would really....ruin everything, for both of us."

To Robin's surprise, Cassie grinned mischievously. "We'll just have to test every time, then - before we....do it, I mean."

"How?"

"I'll have to make you....cum with my hand first, or even....my mouth, like Lucas did, to make sure there aren't any sperms coming out!"

Robin's grin was as broad as his sister's. "Cass, you're a genius! One condition, though." The girl looked at her brother, quizzically. "I get to stroke you, or lick you....down there, at the same time, and make you feel good, too!"

"Oh wow, yes please!" The siblings looked around quickly, and seeing no-one near, kissed briefly but passionately, their tongues entwined.

"Soon, Robbie, really soon!"

"Soon as we can, Cass!"

The next story is already 'in the works', albeit at a rather early stage. Stay tuned! SB

Evolution

Laying in the long grass near the cliff's edge
Watching summer's sun and clouds through near-closed eyes
Smelling the salt breath of the sea
Thinking it would never end

Sitting at the grimy workplace window
Seeing the breeze of another summer
Blowing the tall weeds back and forth
Covering and uncovering the weary city

Feeling tears prick at the corners of my eyes
Remembering all that's come and gone
Aching inside as I ponder the hurts
Wondering how the boy got so lost

6/5/72

Would that a moment
Of insight, beyond my years
Had been present that day
That sunny day in a city far away

When I saw you, when I became
A moth to your flame
Why could I not have known
Where my life would lead

Had I caught a glimpse
Of all that ensued
I could have done
One worthwhile thing

Gone to my room
Locked the door
Taken the blade
And ended the pain

For always

"I can't believe your mum and dad let us do this! It'll be brilliant!"

"And I can't believe your mum let you do it with us! We've asked her loads of times if we can have a sleepover together, but she's always said no."

"I think it's because your mum rang her, and said it was for charity, and we wouldn't be outside, or anything. It's such a great den, too! Did you make it?"

"Robin and I did it together, and Dad helped us, too, moving the furniture and that kind of stuff. Mum sorted all the bedding out, and found those old curtains in the airing cupboard for the roof of the den. She's got us loads of snacks and things as well. This is going to be great!"

"Well....yeah, but...."

"But what?"

"I....I just wish Robin wasn't going to be with us. Boys always spoil everything!"

"That's not fair, Amber! Robin isn't like that! He's the best brother, I love him! This was all his idea, anyway, he saw an advert on the tube, and asked Mum and Dad if we could do it. He e-mailed and got all the information himself. He couldn't be left out, no way!"

Amber was thoroughly taken aback at her best friend's indignation, stammering an apology. "S....sorry, Cassie, I....I didn't mean to upset you. I....I know Robin's nice, h....he's not like some of the....other boys at school."

"Well, some of them are pretty horrible, but not my brother! He should be back soon, anyway. He's over at Charlie's, helping with their den - Charlie and his big brother are doing Den Day, too - Dad's going to pick Robin up on his way back from work. Then we can all get in our den, and start having fun!

****

"You're joking, right?" Charlie's tone was incredulous. "Amber Wicks is going to be in your den? All night?!"

"Yeah, she's Cassie's best friend. Cassie invited her, but no-one thought she'd be able to come over, her mum is mega-strict, Amber's never usually allowed to do anything. Our mum rang her mum, though, and persuaded her, somehow."

"Blimey, Rob, you're so lucky!"

Robin was genuinely nonplussed. "Lucky? Why?"

"Duh! Because Amber's the hottest girl in the whole school, even if she is only a Year 5! You've got to try and snog her, at least!"

"Yeah....I guess." Robin's vapid response seemingly eluded his friend completely. And even if Charlie had known the reason for Robin's lack of enthusiasm, he wouldn't have believed it. The truth was that, to Robin's eye, there was one girl at their school who was in a completely different league from Amber, and all the rest - his beautiful sister, with her shoulder length light brown hair, lovely hazel eyes and stunning smile, not to mention her friendly, loving personality. Robin adored Cassie, had done so for as long as he could remember, and she loved him back, too, he knew that. Why did she have to be my sister, the boy thought for the umpteenth time. If she wasn't, I'd ask her to go out with me in a second.

"She might even let you....do sexy stuff!"

"Now you're joking, Charlie! Amber'll never do anything like that, she'd be too scared of her mum finding out! And even if she would, Cassie's going to be there. I'm not going to do sex stuff in front of my sister, am I?!"

"Wait till Cassie's asleep! And anyway, if Amber gets to see that monster you've got hiding in your pants, she'll forget all about her mum!"

Robin blushed instantly, but grinned in boyish pride, too. He'd known for a while, from sights seen in swimming pool changing rooms, that his penis was quite a bit longer than most other boys of his age, and seen where that advantage had come from, too - his dad was a very well-endowed man. Charlie's knowledge of Robin's 'good fortune' had come about a couple of months earlier, at the end of the Easter holidays, when the two friends had had a sleepover at Robin's house. Charlie was keen to share the lessons that he'd learned from his 14 year old brother, Lucas, when they'd shared a bedroom at the cottage their family had rented for a week away earlier in the school break - Charlie had woken early one morning, catching Lucas at the climactic moment of the immemorial act beloved of virtually every pubescent boy. The brothers were almost as close as Robin and Cassie, so rather than being angry, Lucas had instead explained the process, before coaching his younger sibling through to the shivery intensity of his first ever dry orgasm. Charlie wasted little time in giving Robin a practical demonstration on that Friday night in Robin's bedroom, before encouraging his friend to follow his example. Try it, Rob, he'd said, it feels awesome. As soon as Robin had hesitantly lowered his pyjama bottoms, Charlie's eyes had stretched wide in disbelief. Yours is huge, he'd gasped, almost as big as Luc's! Later in the evening, after Robin had, indeed, discovered that Charlie was right about the 'awesomeness' - twice in half an hour, in fact! - a ruler had been located in a desk drawer, and a quantitative comparison of the two boys made. Charlie had come in at a respectable, for an 11 year old, eight centimetres, but was thoroughly eclipsed by his best friend. Twelve centimetres, Rob, Charlie had gushed, that's amazing! Between the memories of that sleepover, and thoughts of the two girls he'd be spending the night with, Robin felt the now familiar tingle and surge of tightness in his groin as his body tipped into the arousal it had been on the verge of for the previous few minutes. Charlie noticed the growing bulge in his friend's shorts, and smirked.

"Thinking about Amber already, eh?!" Robin grinned sheepishly, but said nothing. "Luc tried to get Mum to let his girlfriend come over tonight, but all he got was her schoolteacher voice, he said - 'I think you know the answer to that question already, don't you, Lucas?'! I'm glad Mum doesn't teach at our school, that would be so weird!"

Robin giggled, partly in amusement at his friend's pitch-perfect impression of his mother, but also somewhat in relief at the change of subject.

"Yeah - I like your mum, but I bet she'd be dead strict as a teacher!" Just at that moment, the boys heard a car horn sound in the street outside. Robin looked out, and saw his dad's car at the kerbside. "Gotta go, Charlie! Have a good night!"

"I bet I don't have as much fun as you will, you lucky git! Give Amber a snog for me, too!"

Robin grinned again and gave his friend's shoulder a playful shove before heading for the door. As he got out of the car, back at home, Robin looked up, to see Cassie at her bedroom window. The girl smiled sweetly, and gave him a little wave. Robin smiled back happily, but, as he went through the front door, the smile changed to a smug little smirk. Maybe something could happen tonight, he thought. A plan began to take shape in the boy's mind. Maybe, just maybe....

****

Cassie woke to the feeling, rather than the sound, of an almost voiceless whispering in her ear. It was late, nearly midnight by the little battery clock that normally sat on her brother's bedside cabinet, the girl having been asleep for a little more than an hour after a busy evening of food, fun and games. When the siblings had set their den up the evening before, they'd found it was too dark inside with all the drapes lowered once the daylight coming through the living room windows had faded, so their dad had retrieved Cassie's old nightlight, an item she hadn't used since she was 5, from the garage, its faint orange glow providing enough illumination to prevent the den's occupants from falling over each other if a visit to the toilet, or some other eventuality, became necessary.

"Look what Robin's doing!"

Cassie was one of those people who virtually never lingered in the shadowlands between sleep and wakefulness, usually fully alert within moments of her eyes opening. Even if that hadn't been customary for her, though, what she saw as she raised her head and looked over towards the opposite side of the den, where her brother had bedded down on a foam camping mattress, would have grabbed her attention in a heartbeat. Cassie gulped in a big breath, only barely managing to avoid calling out to Robin, such was her surprise. Instead, she turned her head, her lips almost touching Amber's ear.

"Wow, oh wow!" Cassie breathed.

"I know, right!" Amber replied, almost inaudibly. "I....I've never seen a boy's....you know what before!"

Cassie, for her part, had seen her brother, indeed her parents too, naked before, but it wasn't a common occurrence - the family weren't nudists, or even close, but they weren't fanatically prudish in the privacy of their own home, either - but what she hadn't seen was Robin as he was now, slowly stroking his full erection with a blissful look on his handsome face. The girl shivered involuntarily, feeling butterflies in her stomach and the beginnings of dampness between her own legs. She knew that meant she was starting to feel sexy, her mum had explained the response to her a few months earlier when Cassie had woken from an unremembered dream with soaked underwear, and had been so upset because she thought she'd wet the bed, like a baby.

"Ssshhh! Let's watch what he does!"

Robin had heard, straight away, the rustlings from the double air mattress the girls were sharing, and the faint sibilance of their whispering, even if he couldn't begin to make out what they were actually saying. Were they disgusted? Or were they interested? Was his plan working, or not? As the seconds passed, though, all speculations were driven from his mind by the tide of pleasure washing out from his groin. His breathing quickened and shallowed, and, all too soon, as ever, he knew he'd reached the point of no return. The boy clenched his teeth so hard, in his determination to stay quiet, that he thought his jaw might break, but even that effort couldn't suppress the little whimper that escaped him as the strongest orgasm he'd yet experienced shook his young body to the core. His penis pulsed drily at least a dozen times before the sensitivity became too much, and he had to let go, his pent breath escaping his lips in an audible rush. Robin instinctively rolled onto his side, his knees drawn up to his midriff, his back to the girls, and pulled his light blanket across his body. He was asleep within moments.

"What happened?" Amber asked her friend. "What was Robin doing?"

"I don't know," Cassie replied honestly. She knew she desperately wanted to find out, though.

****

Go to sleep, go to sleep, Cassie intoned in her head. Amber had been skittish for half an hour or more after Robin's 'show', but, at length, her breathing had evened out, and she'd descended into unconsciousness. Cassie allowed a few more minutes to pass, then blew gently into Amber's ear. Not a flutter. Now, then, Cassie thought. She slipped out of the far side of her bed, creeping silently, head bowed to avoid the top drapes of the den, until she found her way to her brother's side. She knelt down, laying her hand on the nape of the boy's neck. Robin stirred within seconds.

"Hi, Cass."

The girl kissed his cheek. "Hi, Robbie." The boy smiled gently. No-one, no-one at all, was allowed to call him Robbie. Except his sister. Any more than anyone other than Robin was allowed to call his sister Cass. It was the siblings' secret code of their love for each other. Cassie took Robin's hand, squeezing it gently.

"Robbie...." the girl began hesitantly. "W....what were you doing....before? I....it looked like....you were....really enjoying it. D....did it feel good?"

Robin's cheeks flushed a little, and he paused a moment before answering. He'd planned to let one or other of the girls catch him, as Lucas had been caught, but there was still an undercurrent of embarrassment that Cassie had seen him....playing, as he called it in his head.

"Y....yeah, it felt great, the best one I've had, I think. It was....exciting, kind of knowing you and Amber were watching."

"Do you do it lots, then?"

"I....I dunno - most days, I suppose. I haven't been doing it long, though, Charlie taught me how when we had that sleepover just before we went back to school after Easter."

There was a long silence, but there seemed to be some kind of unspoken communication between brother and sister. Cassie, barely, managed to speak first.

"C....can you....show me how it works, Robbie? Please?"

Robin felt like squadrons of butterflies were practising aerobatics in his stomach - and he knew, too, that he was as hard as he'd ever been in his life. The prospect of any sort of sexual play with his gorgeous, beloved sister was so exciting to the boy that he was almost hyperventilating.

Y....yeah - if....if you want." Cassie looked at him, a serious but expectant expression on her face. There was a last thought, in the back of Robin's mind, that maybe he shouldn't go through with it, that she was his sister, after all, but the near-pubescent hormones coursing through his body washed the final shreds of inhibition away, and he pulled his blanket aside. Cassie gasped.

"Robbie - it's s....so big! Do all boys'....penises get this big when they're feeling....sexy?"

"I....I don't think so, I think mine's....bigger than usual for my age. But Dad's got a big one, too, you know, don't you, you've seen him undressed. Maybe it runs in the family."

"I....it's....beautiful, Robbie!" Cassie lowered her eyes, and drew in a deep breath. "C....can I....touch it....please?"

The boy shuddered involuntarily. "Yeah....I....I'd love you to, Cass!"

Cassie reached out, her fingertips barely grazing the pale pink, swollen flesh. Robin squirmed. The girl's fingers curled gently around his shaft, just applying enough pressure to allow her to gauge the rigidity in her grasp. The boy moaned, much more loudly than he would have wanted. Cassie withdrew as if she'd been stung.

"S....sorry, Robbie! I hurt you, didn't I?"

"N....no, no way, Cass! It felt....awesome! Do it again!" The girl did as she'd been bidden, taking her brother in hand once more. "Oh Cass, that's so nice! Hold it near the top, where the skin joins, and rub up and down, slowly, though, please."

The girl didn't quite get the gist immediately, so Robin carefully guided her hand, and its movements, to maximise his pleasure. After a few seconds, he laid back, let go, and simply luxuriated in the feelings his sister was inducing in his raging body.

"Ooohhh, Cassie, that's perfect, just keep doing it like that!"

In little more than a minute, Robin's body shivered out of control.

"Faster, Cass, faster! Don't stop, please! I....I'm gonna....!"

His orgasm hit with unbelievable force, the delirious spasms surging, it seemed, from somewhere much deeper inside than anything he'd experienced before. The boy's hips thrust up instinctively into Cassie's coaxing hand, his penis bucking against her fingers. All too soon, the corporeal fireworks were over, Robin slumping back onto the foam pad beneath him, panting like he'd just been running for his life.

"Ooohhh Cass, that was soooo good! I love you!"

The girl smiled, but her confusion was obvious. "I....I love you, too, Robbie, b....but I still d....don't understand w....what happened to you."

The boy reached up and drew Cassie gently down towards him, kissing her softly on the lips, before turning on his side and encouraging her to lie close beside him, almost nose to nose.

"I....I don't know that much about it, either, Cass, only what Charlie told me. He did tell me the proper name for it, for the feelings, I mean, but I can't remember it - or....or-something - but he said Lucas told him most people call it 'cumming', spelt with a 'u', not an 'o'. He said it's when the sperms come out when you have sex, but Charlie and I aren't old enough to make sperms yet, it doesn't usually start until you're 12 or 13, Lucas said. Charlie said he saw Lucas squirt his sperms out, though, so that means Lucas could get a girl pregnant, if she'd started her....periods."

"Mum told me about periods," Cassie said, almost to herself. "She told me as well that girls get wet in their....pussy when they're feeling sexy, like boys get....hard. Can girls do....cumming, too?"

"I don't know," Robin admitted. "Girls don't make sperms, though, they have eggs instead that the sperm joins with to make babies when they're older, we learned about that at school. Does it feel good, like kind of tingly-tickly, if you touch yourself? That's what it feels like when I touch my....dick, and then when I rub it, it keeps getting better and better until I get the cumming feelings, so if you feel like that, you should get the feelings, too".

" Y....yeah, Robbie, it does sort-of feel like that. A....and I'm really ....wet....down there at the moment."

Robin looked into his sister's eyes for long seconds, the butterflies taking wing once more. "S....shall we try, Cass? C....can I touch you, try and make you feel as good as you made me feel? Please?"

Cassie gently pressed her lips to Robin's once more. "I....I'd really like that, Robbie," she breathed.

"I....I've never touched a girl before - c....can you show me the best way to....do it, so I don't hurt you, and so it feels nice for you?"

Cassie nodded, mutely, a flush of desire painting her beautiful face. Robin gently nudged her onto her back before moving to kneel beside her, his eyes unwaveringly on the girl's. As though those eyes had asked her aloud, Cassie shifted her hips and quickly lowered her pyjama bottoms and panties, Robin helping her to slide them over her ankles and off. The boy's gaze shifted, as though drawn by a magnet, to the thin, hairless slit between his sister's legs, faintly glistening with moisture in the dim light. The sight caused his penis to throb back, almost instantaneously, to full erection.

"Oh, wow! You....you're beautiful, too, Cass!" Robin extended his arm, his hand moulding itself to the silky softness of Cassie's pubis, his forefinger finding the narrow valley of her vulva. He began to rub softly, slowly, rhythmically, the digit slipping easily up and down, aided by the natural lubricant trickling from within the girl's body. Cassie sighed in pleasure.

"Oh, Robbie, that feels lovely, much better than when I touch myself! Stop, just for a second, though, I want to show you something." Robin, reluctantly, lifted his hand from his sister's body. Cassie's left hand reached down and parted her outer lips, the boy gasping as the never before seen inner anatomy came into view. Cassie used her other hand to point to a small bump near the top of her slit. "Look, Robbie, see that place?" The boy nodded, eagerly. "That's where it's most sensitive. It feels really tingly if you touch it. Be really gentle with it, though, please."

The boy nodded, before quickly leaning down to kiss the girl once more.

"Course, Cass," he whispered, almost into her mouth. "Just tell me if I do it wrong."

The siblings adjusted their positions once more, Cassie parting her thighs wider, and Robin kneeling between them. The boy used the fingers of his left hand to part the outer lips, as he'd been shown, then, as carefully as he could, brought one fingertip to the girl's 'sensitive place'. He tickled it lightly, and Cassie shivered.

"Ooohhh yes, Robbie, feels so good! Keep doing it, just like that!"

Robin continued his gentle caresses, and now that he was confident he was touching his sister in the best place for her, he moved his left hand lower, to explore further. He felt the wetness increase, and within moments, had found its source. That must be her....pussy hole, the vagina, as they'd called it in the lesson at school, he thought, where my dick would go if....if we had....real sex. His penis lurched at the idea, the boy felt as though he was close to cumming again, and without even touching himself. As carefully as he was touching his sister's 'pleasure bump', he began to probe at the inner lips with another finger. Just at that moment, Cassie's rising excitement caused her hips to lift, and Robin's finger sank at least a couple of centimetres into the tunnel of flesh. Cassie groaned.

"Ooohhh Robbie, oh yeah, do it more! Do it deeper!"

Cassie was an active girl, far more athletically inclined than Robin himself, taking part in gymnastics and riding her bike regularly, and, as a result, her hymen had been broken at some indeterminate time in the past, meaning that there was no resistance at all to Robin's finger as it slid all the way into her buttery depths. The girl began to tremble, uncontrollably.

"Something's happening, Robbie, don't stop! I'm getting....the feelings....r....right now!"

Cassie whimpered, and the boy felt the muscles around his finger begin to contract, over and over. She's cumming, he knew instinctively, the realisation touching off another climax in the boy's own body, as though it was his penis buried in her grasping sheath. After long seconds of mind-melting pleasure for both siblings, Cassie slumped back to the mattress, pulling Robin down on top of her. They hugged each other as closely as at any time in their lives. Robin's still throbbing penis slid against Cassie's wetness, causing them both to groan aloud.

"Put it....inside, Robbie. I....I really want to!"

"A...are you sure, Cass?" The boy could hardly believe his ears.

"Really, really, sure! Your finger felt amazing in there, y....your....dick will feel ten times better, I know it! And we can't accidentally make a baby, because you haven't got any sperms yet, and I haven't started my periods. Please, Robbie, let's do sex together!"

"B....but it's bigger than my finger, Cass. I....I don't want to hurt you. I....love you, more than anyone!"

"It's longer than your finger, but not much fatter," the girl countered. "Let's try, Robbie, please. If it hurts, I'll tell you, I promise, and we can stop. Kneel up for a second."

Robin did as she'd asked, and Cassie slid lower, raised her knees and splayed her thighs as wide as she comfortably could, placing herself, although she couldn't have known it, in the classic 'missionary position'. Then she reached out, taking her brother's erection tenderly between her fingers, guiding him to her threshold.

"Push in, darling Robbie, gently, though, slowly as you can."

Robin felt the wetness against the tip of his glans and groaned in his excitement. He edged his hips forward a few millimetres, but seemed to make no progress. Cassie caught her breath. The boy stopped.

"It won't go, Cass," he breathed.

"It will, Robbie. Push a little bit harder."

Robin tried again, and, at the same moment, Cassie rose up a little to meet him. As it had been when the boy had first penetrated her with his finger, there was an almost instantaneous movement of a few centimetres, from outside to in. Cassie grunted, impossible for her brother to know whether the sound was born of pain or pleasure.

"Are you OK, Cass?" he asked urgently.

"Y....yeah, feels good. Feels big, though."

"Shall I take it out?"

"N....no, just give me a second to get used to it."

Robin looked once more into his sister's eyes, and while being careful to keep his hips still, touched his lips to hers. This time, both boy and girl instinctively opened their mouths a little, the tips of their tongues coming together, each tasting the other for the first time. Cassie broke the kiss, looking up adoringly at her brother.

"Now, Robbie, put it all inside me now!"

Robin began easing forward once more, shaking, it felt to him, from head to foot. The warmth, the slick lubricity, the tightness he felt engulfing his boyhood was simply overwhelming. By the time he felt the skin of his hairless pubic mound touch his sister's, the gentle kiss of their flesh signalling, unequivocally, the loss of their virginities, he was close to tears, as much from the emotional overload as from the exquisite physical sensations.

"Oh, Cassie, oh, I....it....it's so, so good! I....I never knew....anything could feel so....wonderful! Does it feel good to you, too, Cass? I w....want it to feel as g....good for you as it does for me, really."

"I....it's amazing, Robbie, just amazing! I feel so full, but it's so brilliant! Go in and out, that's what we're supposed to do, isn't it?"

"Y....yeah, I....I think so. I'll try."

Robin drew back slightly, before once more sinking slowly, fully into his sister's clinging depths, causing them both to sigh at the delicious feelings. Naturally, Robin's inexperience meant that he took a little time to find a smooth rhythm, although he did have the advantage that his long penis meant that the risk of him slipping out of his sister was close to zero. After a couple of dozen thrusts, though, the boy had begun to find the optimum length and speed of stroke, his increasing confidence translating directly into increasing pleasure for both siblings.

"Ooohhh Robbie, so good! You're rubbing against something really nice inside me, it feels fantastic!"

"Cass, it's so fantastic for me, too. I can't believe it, I'm so lucky! I'm h....having....sex w....with the most beautiful girl in the world! I love you so much!"

"I love you too, I can't believe there's a better brother anywhere! Go faster, Robbie, I....I'm going to get the....cumming feelings again, really soon!"

Cassie lifted her legs higher, wrapping herself around Robin's slender hips, seemingly wanting to draw him even deeper into her heaving body. The boy increased the pace and intensity of his thrusting, to the point that a faint clapping sound could be heard in the den as the siblings' bodies came together, again and again. Cassie's breathing quickened rapidly, turning to almost sobbing pants as her excitement reached boiling point. Suddenly, Robin felt a gush of extra wetness around his throbbing erection, then a series of pulsing squeezes as his sister hit her peak.

"Ooohhh yessss! Don't stop, Robbie, please don't stop!"

Robin had no intention of stopping, his own release, he knew, was only seconds away. Twenty, ten, five more jackrabbit thrusts, before the ecstasy hit him like a runaway train, his whole body feeling like it was on fire, his penis seeming as though it might burst at any second before erupting into a series of huge dry spasms, stronger by far than anything he could have imagined. Time had stopped, all that existed for the boy was the searing pleasure exploding through his genitals. His body was on autopilot, his hips somehow continuing to pump without any hint of conscious control. Somewhere, far in the distance, he was dimly aware of Cassie whimpering, then felt the girl's muscles tighten against him once more as she reached a second climax, wringing even more delight from his nearly exhausted body. Then, like a curtain falling, it was all over. Robin's movements stuttered, once, twice, then came to a halt. He had just enough strength left to avoid outrightly collapsing onto his sister's body, easing his light frame down until they were touching almost from head to toe. After long moments of panting breaths from both girl and boy, their lips found each other once more, and they kissed, gently, tenderly. There were no words, both instinctively knew none were necessary. Neither had any doubt, despite their youth, that they had just shared one of the cardinal moments of their lives. Robin's penis slowly softened, and, eventually, slipped from his sister's liquid embrace. Cassie sighed.

"W....we can do that again, soon, can't we, Robbie?" she murmured.

"I....if you want to, Cass, course we can. We'll have to be....careful, though, if anyone finds out....I....I don't know what....would happen."

Cassie nodded unhesitatingly, realising her brother was right. What the siblings had forgotten, though, first in the excitement of their voyage of mutual discovery, and then in the contented afterglow of their lovemaking, was that they weren't alone.

Amber laid awake, her heart pounding in her chest, her mind in turmoil. She'd woken some half an hour earlier, immediately aware that Cassie wasn't lying beside her. After blinking several times as her vision adapted to the low light, she saw her friend kneeling beside Robin's bed. Just then, the boy peeled his blanket away in response to something his sister had said. Amber gasped as Robin's lower body came into view once more, her focus on the long, thin stalk of flesh jutting from between his legs. Her eyes went wide with disbelief as Cassie reached out and....touched it! If that first touch had shocked Amber, what followed as the minutes progressed was completely beyond the girl's comprehension. Cassie had stroked Robin as the boy had done to himself earlier, with, apparently, the same result, they'd then changed places, Robin using his fingers gently to Cassie's obvious delight. Amber squinted to see what the boy was doing to give her best friend such pleasure, just in time to see Robin's forefinger disappear inside Cassie's body. The effect on Cassie was electrifying, she shook, moaned, whimpered, but obviously not due to any sort of pain. Amber's hand, almost unconsciously, slipped beneath the thin material of her underwear, touching what, for her, was almost unknown territory, trying to understand what her best friend was feeling. Robin and Cassie had moved again, laying close together, wrapped in each others' arms. In the absolute silence of the den, some of the siblings' low whispers were loud enough for Amber to overhear, but what she heard next, she simply couldn't believe. 'Put it inside', that couldn't be what Cassie had said. Could it? That would mean....they were going to....have sex? Amber wrenched her hand away from her body. They can't! It....it's wrong, it's....dirty! Amber, just once, a year earlier, had asked her mother, after watching a TV programme about young animals, how people had babies. The look of distaste on her mother's face had been so pronounced that even a nine year old couldn't possibly mistake it. You don't need to know about dirty things like that, the woman had said sternly, almost angrily, that's for when you're grown up, and married. Robin and Cassie weren't grown up, though, and they couldn't get married even if they were, brothers and sisters weren't allowed to, Amber knew that. Didn't they know it was wrong? Amber wanted to stop them, somehow. Should she just tell them not to do it? Should she go and tell Mr and Mrs Beaumont what was happening? Amber was frozen in place, though, unable to drag her eyes away from the unfolding drama little more than a metre away. Robin was now kneeling between his sister's legs, Cassie was guiding his....boything, closer, closer, touching, a momentary hiatus and an exchange of whispers, then - Cassie made a noise that sounded to Amber like her friend had been punched in the stomach, as the top part of Robin's spike disappeared inside his sister's body. Another pause, more words, below the threshold of audibility this time, and then Robin moved forward again. Amber forgot to breathe as the boy's whole length was slowly swallowed by Cassie's insides, until their....private bits were touching together. Then they started moving, well, mostly Robin moving, although Cassie put her legs up and gripped around his....bum after a minute or so, like she wanted the boy to be even deeper inside her. They both looked as though they were in heaven, Amber thought, and, once more, her hand found its way inside her panties, her finger creeping into the deep cleft of her vulva, as she'd seen Robin do with Cassie, just minutes earlier. Amber felt dampness that she knew wasn't wee, even if she didn't know what it actually was, and, as she pressed a little more firmly, caught her breath as a spark of pleasure emanated from somewhere beneath. She moved her finger, experienced another jolt of good feelings, homed in instinctively on the source, a firm feeling lump near the top of her slit, began to slide her fingertip across and around it carefully. She could feel herself becoming wetter, and moved her other hand to investigate. She prodded, hesitantly, at herself for a second or two, then had to almost bite her tongue to avoid crying out as the finger found the opening, and slipped inside to the first joint. That's it, she knew at once, that's where Robin's thing had gone into Cassie! Before she could process her discovery, though, her attention was dragged back to the siblings, as their movements and panting breaths seemed to signal a crucial moment. 'Oh yes, don't stop', Amber heard her friend gasp, while Robin's hips pumped so fast that the girl thought he must be hurting himself, or Cassie, or both of them. But then the frenzy was over, Robin stopped moving and laid carefully down on top of Cassie, they kissed, several times, before finally moving a little apart and sharing another inaudible conversation. Amber caught a glimpse of Robin's 'boything', now seemingly soft and floppy, but visibly wet, from the moisture of Cassie's insides, she realised. Brother and sister languidly retrieved their discarded nightclothes, and dressed slowly, before cuddling together on Robin's bed, the boy behind his sister, their bodies moulded together. It took no time at all until both were asleep. The same couldn't be said for Amber. She simply couldn't equate the 'dirtiness' her mother had referred to with what she'd been observing. Cassie and Robin's pleasure, closeness and love for each other were plain to see - and totally beautiful, not dirty at all. Amber yearned for someone to kiss her like the siblings had kissed each other, to touch her like they had touched. When she did eventually fall into a fitful sleep, it was with tears in her eyes.

****

"You'd better get back into your own bed, Cass," Robin murmured sleepily. "We don't want Mum and Dad finding us like this."

"Do I have to, Robbie?" Cassie asked with obvious disappointment. "Can't we just say I had a bad dream, or something, and that you were looking after me?"

It was 6:00, and the early light of a bright Spring morning was already seeping into the den, even through the heavy material of which it was constructed. "Amber's here, too, don't forget."

"I suppose so," Cassie replied with resignation in her voice. "It's really nice, you cuddling up to me like this, though."

"I know, it's really good for me, too. W....what we....did last night was too fantastic for words, though, a....and I want to do it....lots more, a....as long as you....want to, as well. But if we get....caught...." The boy's voice tailed off, but the message he was trying to convey was crystal clear.

Cassie rolled to face her brother, unhesitatingly planting a melting kiss on his thin lips. "Me, too, Robbie, I want to do it whenever we can. It was the....best thing, ever, ever!"

"I love you, Cass."

"I love you, t...."

"I saw you." The siblings jumped almost out of their skins, the blood draining from their faces. "I watched you....doing it!"

Robin and Cassie moved to cling to each other as if they'd just heard a death sentence. Amber continued, her voice seemingly emotionless, all the more chilling for its neutrality. "Why did you do it? Children aren't supposed to, it's only for grown-ups. My mum said so." Neither sibling could find so much as a word, still less a coherent answer. Amber focused her attention on her best friend, her icy carapace dissolving by the second. "D....did you like it, Cassie? Did it feel good?" Cassie nodded, mutely. "And Robin didn't hurt you?"

"N....no, Amber, really! It felt....weird, just for a second, sort of....too full, when he first put his....dick inside me, but it didn't....hurt, I promise! And then it started feeling really, really nice, really quickly."

"Are you....going to tell on us?" Robin asked, nervously.

Amber looked at the boy blankly, as though the question had been asked in some incomprehensible language. Cassie picked up on her friend's hesitant confusion.

"Please don't tell, Amber! I don't want Robbie....Robin to get in trouble, I love him, loads!"

"I....I don't know....w....what to do...." Amber began, but her overwrought emotions caught up with her, and she started to cry. Cassie instantly disentangled herself from Robin, scooted across to her friend's side, and wrapped her up in a close hug.

"Don't cry, Amber, please don't!"

"S....sorry, Cassie," Amber managed after a few moments. "I....it's just that....I don't....understand. Mummy says....it's dirty, b....but you a....and Robin....well, it didn't look....dirty at all. I....it looked....lovely."

"It was lovely, Amber. Robin made me feel better than I've ever felt in my whole life." Cassie paused. "H....have you....ever touched yourself....down there?"

Amber flushed with embarrassment. "No! Well, n....not really. M....maybe a....little bit, when I was....watching y....you and Robin....doing it."

"Did you like it?"

"I....I don't know - I....I suppose so. I got....all wet. D....does that happen....to you, too?"

Cassie smiled. "Yeah! That's what supposed to happen when you're feeling....sexy. Mum told me about it. Like Robin's....dick gets....hard. Boys get hard, and girls get....wet. I....it's so the boy....can go....inside the girl more easily."

"Did your mum tell you that?"

"No, but I....kind of worked it out, earlier on. When Robin first put....his finger in me, it slid right down inside, really easily, and didn't hurt at all. It wouldn't have been like that if I hadn't been....slippery, I bet!"

"And it really felt....nice, having....something....inside you, like that?"

"Honestly, it felt great!" Cassie looked into her friend's eyes. "Y....you should....try it, Amber. Then you'd find out for yourself!"

Amber's head felt like it was about to explode. The diametric opposites, her mother's utter disapproval against Cassie's enthusiastic advocacy, were too much for her to come to terms with. Not knowing, at all, what to say, she said nothing. She felt Cassie snuggling closer to her, sensed her friend's warm breath beside her ear.

"Do you want to, Amber - try, I mean? I'll show you what to do, if you want."

Once more, Amber couldn't find any kind of reply. Cassie decided that her friend's lack of a rebuttal was close enough to assent, and gently slipped her hand between Amber's legs, outside her nightclothes, cupping her pubis. There was a momentary, instinctive closing of Amber's legs, but all that was achieved was to increase the pressure of Cassie's touch, sending a warm wave of pleasure through Amber's lower body. The girl moaned softly.

"Nice?" Cassie whispered.

"Mmmm, I like that."

"Shall I carry on?" Amber nodded slightly, and Cassie began to move her hand slowly, massaging the sensitive area carefully. Amber, after a few seconds, began unconsciously pushing herself up into Cassie's palm. Her eyes closed, while her lips parted a little as the new and exciting feelings began to build.

"Let's get....undressed, Amber," Cassie whispered, "it feels better....naked."

Once more, Amber didn't demur, so Cassie gripped the waistband of her friend's pyjamas, and began to ease them over the girl's hips. Amber neither resisted nor assisted, but, within seconds, only her underwear was covering her girlhood. Cassie touched the front of Amber's panties gently.

"Gosh, you are wet! Shall we take these off, too?"

Amber's underwear quickly went the way of her pyjamas, followed by the T-shirt she was wearing. Cassie and, behind her, Robin, both gasped.

"Wow, Amber!" Cassie exclaimed. "Your....boobs are....so nice!"

Cassie was more or less completely flat-chested, but her friend had undoubtedly begun the voyage into puberty - her nipples were probably twice as big as Cassie's, atop breast buds each the size and shape of half an egg. Robin, in particular, was totally fascinated by Amber's form and shape, his penis responding accordingly, completely rigid in moments.

"A....Amber?" the boy breathed. "Can I touch your tits....I....I mean your....breasts, please? They really look...awesome!"

Amber looked almost panic-stricken, impelling Robin to try and reassure her. "I'll be ever so careful, I promise."

"O....OK," Amber replied, before drawing in a huge breath as Cassie's fingers gently touched her naked flesh for the first time. Robin crossed the den to Amber's left hand side, then tentatively reached out, allowing his fingertips to brush lightly against Amber's nipples, first the left, then the right.

"Ooohhh, Robin! Do that again, that's sooo nice!"

The boy shifted his position a little, kneeling close to Amber so that he could use both hands on her body. He ran the balls of his thumbs across the sensitive nubs, delighted to see and feel them growing and stiffening at his touch. Meanwhile, his sister had begun to dip a finger between Amber's labia, slipping easily through the girl's increasing wetness. Amber instinctively spread her legs wider as her pleasure leapt to previously unimagined heights, her eyes closed and her head beginning to loll left, then right, as the siblings continued their gentle ministrations. Much as Cassie had earlier, in response to her brother's stimulation, Amber's hips lifted, causing her friend's fingertip to penetrate the inner lips, and slip a centimetre or so into her sopping vagina. Amber groaned at the new sensation, thrusting up deliberately to impale herself on Cassie's probing finger.

"Ooohhh yessss! Oh, Cassie, that feels wonderful! More, please, more!" The girl was getting a little over volume, Cassie shushing her urgently, lest her parents should hear. With all the willpower she possessed. Amber forced herself to remain silent as the combined delights of three hands on and inside her body tipped her over the edge of her first ever orgasm, her hips jerking spasmodically as Cassie continued to slide her finger rapidly in and out of her grasping tunnel of flesh. Then it was all over, Amber's body suddenly seeming to lose all its strength as she flopped back heavily onto the mattress, her breath coming in huge gasps.

"Ooohhh, wow!" Amber exclaimed after long seconds. "Wow, wow, wow! That was....was....unbelievable! Did it feel that good when you and Robin were....doing it, Cassie?"

Cassie nodded, wordlessly. Amber turned her head to look at the boy, her gaze falling greedily on the, to her, massive bulge in Robin's pyjama trousers, before looking into the boy's eyes.

"I....I want to try it, t....too. C....can we, Robin....please, please?"

Brother and sister looked at each other, amazed at the sudden change in Amber's demeanour, from the demure, innocent girl they'd known for years, to this....hunger, there was no other word for it.

"W....would you m....mind if we....did, Cass?" The boy felt like he'd almost forgotten how to speak, such was his excitement.

Cassie's emotions were almost painfully mixed. She wanted her brother to give and get the same pleasure with Amber as they'd shared just a few short hours before, wanted her friend to experience the delights of the ultimate act of intimacy, but she couldn't help but feel that Robin should be hers, and hers alone. Seconds passed. Amber broke the tableau.

"Please, Cassie! I know you and Robin....really love each other, but I....want to try, so much. Please can we? Just this once?"

Even as Cassie's mouth opened, she seemed hardly to know which words would emerge. "O....OK, then, as long as Robin....doesn't mind, I d....don't."

Robin smiled straight into his sister's eyes, before leaning across and kissing her lips gently, lovingly. He moved his face close to Cassie's ear, whispering almost inaudibly.

"I....it'll be different, Cass, I know. I don't....love Amber, b....but I really, really love you, and I always will, I promise. Thank you for letting me....try with Amber." The siblings kissed again, before Robin quickly shucked his nightclothes and turned his attention to the girl at the centre of the bed. Amber reached out and took the boy's erection carefully in her hand, exploring its shape and texture.

"I....it feels....so hard, Robin. Will it hurt when you...put it in....inside."

"I....I'll be as careful as I can, Amber, promise. D....do you want....to do it now?"

"Oh yes, yes please!" The youngsters arranged themselves as the siblings had earlier, Robin guiding Amber's hips lower and wider, kneeling between them. This time, it was his hand that moved his own penis to touch Amber's wetness.

"Ready?" The girl nodded, and Robin slowly, slowly, moved his hips forward, feeling the slickness and heat of a girl's body begin to envelope him for the second time in his life. Amber whimpered, just once, as a small sting of discomfort shot through her lower body, but it passed in a handful of heartbeats as the boy continued to carefully penetrate her depths, until there was no further to go. Their eyes met.

"OK, Amber?"

"Y....yeah. It feels....oh, it feels great!"

"I'm going to start....doing it. If you want me to stop, or do it....differently, just tell me, OK"

The girl smiled. "OK, Robin!"

The boy's thighs drew back, then thrust forward firmly, finding a smooth, slowish rhythm almost immediately.

"Uh....uh....uh," the girl grunted in time with Robin's movements. "Uh....y....yeah....just....like....that, i...it....feels....fantastic!" Within a couple of minutes, the girl began to pant heavily. "T....the....feelings....you're....going....to....give me....the....feelings!" Robin increased his pace markedly, and Amber crashed into climax, burying her face in Robin's shoulder to prevent herself crying out as the pangs of ecstasy coursed through her young body. Neither boy nor girl knew about multiple orgasms, needless to say, but Amber experienced just that, a second peak, almost as intense as the first, rippling through her just as she felt Robin's hardness begin to pulse wildly inside her as he went over the edge himself, the boy groaning aloud at the glorious sensations. Movements slowed to a stop, and Robin withdrew, breathless.

"Th....thank you, Robin, that was....so good. And thank you, Cassie, for sharing Robin with me. You're the best friend I could possibly have!"

Cassie smiled, genuinely happily. She really liked Amber, she loved Robin more than ever, and watching her best friend and brother together had been unexpectedly exciting, too. Cassie looked at Robin, grinning wickedly.

"Reckon you can do it again?" The boy's penis had begun to wilt, but quickly reversed direction at his sister's words. He nodded enthusiastically. "Good, because I want my turn!"

Two hours later, Mr and Mrs Beaumont walked into the living room, the woman lifting a corner of the drapes to take a surreptitious peek into the den. All three youngsters were in their respective beds, sleeping like babies. Mrs Beaumont smiled knowingly at her husband.

"Up half the night talking, I bet! Shall we give them another hour before I start sorting their breakfast out?"

"Don't see why not," the man replied. "It'll be nice for us to be able to have our breakfast in peace, for once!"

Charlie made a beeline for Robin as they made their way into school on Monday morning.

"Get to snog Amber the other night?"

Robin smiled crookedly, blushing a little. "Nah," he replied, truthfully.

"Wuss!" Charlie smirked. "I learned something new from Luc. It was great! I'll show you next time we have a sleepover! What about at mine this weekend?"

"I'll ask Mum and Dad!" Robin grinned. I bet you didn't learn as much as me, though, he thought smugly.

Love & best wishes to all

This might be the first in a series of adventures for Cassie, Robin and their friends - I like the siblings a lot! As ever with my literary endeavours, no promises, though!
