Late Friday night, long after the nameless blonde boy has left and my entire family has returned home, the burning sensation in my throat still hasn't subsided. Although I find it slightly strange that swallowing the 11-year-old's sticky cum would irritate me so, it doesn't seem like anything to worry about and I soon fall asleep to vivid dreams of the amazing - if unsolicited - events of that afternoon.

Although thinking about "gay" stuff like huge dicks and sperms spewing over my face is getting to be more arousing than disturbing, my true longing is to have a body just like the blonde boy's - simply so I can do to someone else what he did to me! Still, I'm logical enough to know that wish is an impossible fantasy, and for the immediate future I'm stuck with the "baby dicklet" I have. I really don't know why he had to be quite so insulting like that - I may not be freakishly big, but what I have still makes me feel very good!

The next morning, I awake with a start. Blinking my eyes open in the bright sunlight streaming through my eastern-facing window - the custom blackout blinds haven't arrived yet - I listen for any strange noises in the house.

Nothing.

Turning onto my side, the clock on the nightstand reads just after seven AM. Normally no one gets up on a Saturday until eight or nine o'clock, so I'm not sure what woke me - until I discover that I've got raging morning wood and need to pee really bad. Damn it! Reluctantly throwing the covers back, I haul myself out of my comfortable bed; the one thing of mine that's still completely familiar from our old home.

Standing upright, I feel dizzy and lightheaded for a few seconds and stick out a hand to steady myself against the dresser. The sensation soon passes, and I shuffle barefoot out my bedroom and into the hall.

Just when I'm about to turn into the main bathroom, my sharp ears hear strange sounds coming from further along the hall. They're soft and muffled, a bit like giggling and whispering. Curious, I creep towards the noises, which seem to be coming from inside my little sister Dee's bedroom.

Is she up already? That's not like her at all!

Her door is closed to just touching, and pressing my nose to the crack I can only make out the vaguest hints of blurry motion. Carefully pushing it open a few inches while praying that the hinges don't squeak and give me away, I peer inside... and am so completely baffled by what's happing on the inside, that my jaw falls open and I blink rapidly, wondering if I'm still lying in bed dreaming.

There's Dee, my 7-year-old sister, sprawled on top of her brightly colored bed sheets with her knees bent up and legs splayed wide apart. The curly-haired brunette's light pink pajama bottoms are shoved halfway down her thighs, and since her bed faces the door I'm presented with a perfect view of the vertical slit of her hairless little pussy stretched open into a glistening wet gash of shiny pink skin. Why does her pussy look so puffy and wet?

Of course, I occasionally see my sisters naked in day-to-day life, but never once in such an explicit pose!

But as amazing as this unexpected view is, it's what's happening on top of Dee that quite literally blows my mind.

Chloe, our blonde 13-year-old big sister and star junior cheerleader, is utterly naked and squatting directly over Dee's head. She's facing away from the door and moaning softly, her arms braced against the white painted headboard as she bucks her hips and grinds her crotch into our little sister's face with a surprising amount of force. Not only is the whole bed shaking back and forth as she moves, but Chloe's pressing down so hard that Dee's chin is repeatedly pushing between the plump swells of her big sister's buttocks like Moses parting the Red Sea... and her chin even looks soaking wet!

Geez - did the whole planet go nuts since Thursday? First that freaky blonde boy with the huge cock sperms all over me, and now I catch my two sisters behaving the exact opposite of how our conservative parents always raised us.

It's gotta be the Arizona heat!

"Uhh, c'mon already Dee, I need to come!" hisses Chloe urgently. "You gotta make it come out before everyone gets up!"

All I can hear coming from beneath Chloe are Dee's muffled slurping sounds.

Wait - slurping? Is she actually licking Chloe's pussy? That's a lezzie thing! Wow - I never would've imagined my sisters doing anything like this in a million years!

My eyes dart back and forth between Chloe's surprisingly shapely ass clenching and dimpling as she humps her sister like an inanimate stuffed animal, and Dee's glorious 7-year old pussy aimed right at me. Dee adjusts her position on the bed, and as her pink gash stretches a little wider, the mouth of her pussy suddenly pops open into a teardrop-shaped void nestled just above the curves of her little buttocks.

Wow - her hole is way more visible than I would've imagined for a girl of 7! She could easily get some fingers in there!

I'm finding it hard to believe that any of this is actually happening, but the sights, the sounds... they're like nothing I've seen before, so how could I possibly imagine them? Even the air smells strange, perfumed with a scent I can't begin to place, but one that seems to be making my piss-hard throb and twitch in my pajamas like it's got a mind of its own.

"Uhhh, lick me hard, Dee - push your tongue in deeper! Ooh, it's gonna happen soon! Dee - squeeze my bum, you know I like that!"

Shit! Really? That biological programming to ignore naked family members is long gone - these two girls look sexy as hell, even if they are my own siblings!

Dee's little hands come up and obediently grab her sister's ass; her fingers digging into the crack and pulling apart the soft globes of flesh like she's done it many times before.

"Oh yes! Yes! Just a few more seconds! Get ready Dee - agghhh!"

Chloe's brutal face-riding reaches a fevered pitch, and with a sudden convulsion that causes her entity body to spasm like she was just electrocuted, her thighs clamp around either side of Dee's head and her spine arches sharply in reverse.

"Uggghhh, yes yes!" she wails through clenched teeth, trying but ultimately failing to keep her voice down. "Oh god, baby girl - I'm cooomiiiing!"

Watching in stunned silence from the doorway, I can't actually see signs of much happening beyond Chloe's hips making little jerking motions. However, within a few seconds Dee's stomach is pumping up and down quite dramatically, and I begin to wonder how the girl is able to breathe with her face completely smothered by her sister - and when her hips suddenly begin bucking hard like she's trying to shake Chloe off, it dawns on me that she probably can't breathe at all.

My heart pumps furiously as I watch my two sisters with great concern. Is Chloe so caught up in her orgasm that she's accidentally hurting Dee? Oh shit - I have to put a stop to this before it's too late!

Shoving the bedroom door open all the way, I rush up to the small bed to yank Dee by the feet out from under her big sister's suffocating ass, but just as I reach the footboard Dee's hips thrust upwards at the exact same moment as a thin jet of liquid squirts out from the pink gash of her pussy - the stream sputtering between her quaking thighs, past her dainty feet, and finally splashing harmlessly near the end of the bed.

I stop dead in my tracks, gawking at the unexpected puddle of wetness as it rapidly soaks into the sheets.

What the hell was that?! Is she peeing?

Dee's ass drops back to the bed and immediately jerks back up again, and this time her immature pussy ejects an even larger gush of liquid with so much pressure that it shoots clear over the end of the bed and splatters all over my pajamas - painting a wet line that reaches from my upper chest all the way to my crotch. The liquid is boiling hot and curiously fragrant, and foolishly the first thought to pop in my head is to wonder how I'll explain to mom why my own sister peed on my pajamas.

After a third weak squirt barely makes it past her knees, the little girl visibly relaxes just as Chloe lets out a low grown and collapses forwards against the headboard, panting heavily. A few breaths later she shakily lifts her crotch up from her little sister's face, who immediately sputters and coughs and takes in a huge, wheezing lungful of air. Still wobbly, Chloe slides her legs alongside along her sister's body until she's laying flat on top of the girl, with their two stunning pussies stacked up into a single vertical slit.

Humming and giggling entirely inappropriately considering her sister's obviously distressed condition, Chloe spreads her knees wide and locks her legs around Dee's diminutive frame, intentionally pressing the gentle rise of her mons into her baby sister's. I can't help but notice how my big sister's sex is like an oversized version of my little sister's - except Chloe has a few wisps of light brown pubic hair just above her slit, and there's these two funny pink flaps of skin sticking out from the middle of her gash, while Dee just has a perfectly smooth groove.

Chloe purrs and kisses Dee repeatedly on the lips. "Oh my... oh Dee, thanks so much! That was just fantastic!"

Although she still hasn't caught her breath, Dee tries to speak. "So much... couldn't breathe... so good!"

"Mmm... yeah, you made me come real hard that time! I thought I was never gonna stop."

With her breathing more under control, Dee giggles. "Me too, Clee! Hey, guess what? I got my big tingle without even touching!"

"Oh! Did that happen again? You're getting your tingle so easy these days! See? Didn't I say my cunny juices would make you feel like a big girl?"

Cunny juices?

Dee wraps her little arms around her sister and hugs her close. "Yeah, you was right! I really like playing with you, and so does my cunny! When my tingle came up I started seein' stars, and even I think I made juice just like you!"

"Really!" squeals Chloe in excitement, jumping up and spinning around to look at her little sister's pussy - which is precisely when she notices her brother standing a few feet away at the foot of the bed, frozen in place like a stupefied statue.

Instantly she makes a high-pitched squeaking sound, slapping a hand over her own exposed pussy and moving an arm across the puffy little cones of her budding breasts - completely forgetting about her equally naked sister's need for modesty too.

"Oh my god, Brandon! How long have you been standing there! I swear it's not what it looks like!"

Glancing down at my soaking wet pajamas and then over at my baby sister's gaping pussy, I slowly tilt my head upwards to look pointedly into Chloe's panicked eyes. "Um, I sure hope it's exactly what it looks like. And I've been standing here about long enough to wonder why I've never been asked to join in!"

"No, I swear we aren't, it's just that we're... um, wait... you mean you aren't gonna tell mom and dad on us?"

I roll my eyes and snort. "Of course not! Why would I do that?"

"Oh thank god! You have no idea-"

"But c'mon, Chloe..." I interrupt. "You and Dee, doing this? I mean you gotta know I need to get off just as much as you two, so it's totally not fair that I've been having to do it all by myself!"

"We're not... but wait. You mean... you play with yourself too?"

"Yeah, of course I do! Doesn't everybody?"

My big sister sucks air through her teeth. "Um, no, not that I know of, little bro... I didn't even think you knew about playin' naughty. You're so young..."

"Hah! You're only like a few years older! And what about Dee? She's way younger than me!"

"Yeah, but we're both girls... and both, um, like super horny. Sisters can just do this kinda stuff for each other..."

"And you really think your brother wouldn't want to help out? You two aren't the only horny ones around here, you know!"

Chloe looks down at her lap for a moment, and with a meek smile removes her protective hand... wordlessly informing me that it's okay to look at her surprisingly curvy 13-year-old body. Which I do with relish! "Um, so you're horny too, huh little bro? Oh, wait, I know! Is that why you've been so miserable lately?"

"No! I mean yes... well... I guess it's kinda complicated. You know I didn't want to hafta move out here to stupid hot Arizona and lose my one and only best friend. I thought you two felt the same as me, but then this whole week there you are, rubbing it in my face by making friends at school like it's easy, and being so damned happy all the time... and now I see why that is. You've got each other, while I've got no one! I'm always left out of everything around here!"

"I'm sorry, Brandon - really I am! But mom and dad and the teachers at school say stuff like what me and Dee do isn't right, so I know we hafta keep it secret... and I always figured if you found out, you'd say we're freaks an' tell mom and dad on us, and then we'd have to stop forever."

"That's crazy! I'd never do that to my own sisters! I mean, we're family... you know me... I'd only ever want to make you both happy, whatever that takes. I just can't believe you thought I'd tell on you instead of wanting to join in! It's like you don't know me at all!"

Looking up, Chloe and I lock eyes - her expression a mix of relief and understanding, and mine hopefully one of indignant disappointment.

"Oh Brandon, I really didn't know you'd feel this way! But you're our only brother, so I promise you can join in whenever you want from now on! But why... why didn't you ever say anything yourself?"

I arch my eyebrows and grin toothily. "Because I didn't know you knew about playing naughty... and always thought you'd tell on me!"

The two of us laugh in a shared moment of understanding, which Dee takes as an opportunity to whine.

"Branny... make Clee get off me already! I gotta see if I made any cunny juice before it's all dried up!"

Dee quickly unhooks her knee from around her sister's waist and climbs off the narrow mattress, standing next to the bed and grinning at the two of us like an unduly proud mother. "Oh, you sure did make juice, baby girl... you got it all over the bed, and even our dear brother!"

"Oh wow!" exclaims Dee, her eyes going wide when she sees my drenched pajamas. "I'm so sorry, Branny!"

I chuckle as I tug the wet fabric away from my chest and let it snap back. "Uh, it's perfectly fine, of course... but uh, what is this stuff? I thought it was pee at first, but now I'm not so sure."

Chloe shrugs. "Beats me! Though don't worry, 'cuz it's not pee. Same stuff started squirtin' out my cunny a year or two ago whenever I made myself come super hard." She pauses and blushes, obviously finding this subject awkward to talk about with her little brother. "Anyways, now it won't stop. But I don't mind, since it's fun to do and Dee says it tastes real good, though personally I don't think it tastes like anythin'. Hey! Now she can do it for me - I mean for us! I'm sure you'll totally like it too, bro."

"Oh, I'm sure I will," I murmur in reply. I'm still not completely convinced this isn't some wild dream!

Dee places her palm flat on the wet spot on her bed and giggles happily. "This is so cool! I really did it! I'm so happy I'm your sister, Clee!" Then, she looks up as if something just occurred to her, and stares directly at the front of my pajama bottoms. I'm rock hard and throbbing, but you'd be hard pressed to tell. "Uh, Branny... you're our brother... so do you, uh, make any juice like us when you get your tingle?"

For an instant, I wonder what Dee actually knows about boys at her age. But since I just watched my 7-year-old baby sister squirting cum - something girls aren't even supposed to be able to do - I'm far too self-conscious to admit that I've never been able to make any of my own. "Um, yeah, of course... but when boys make sperms - uh, that's our juice - it's a lot different than what you did."

Dee tilts her head quizzically. "Oh? Tell me, Branny!"

I flash back to yesterday afternoon and that nameless freak spewing his gooey strings of cum all over my face and down my throat. Geez - what I wouldn't give to have his endowments right about now for a proper demonstration! "Yeah... well, uh, boy sperms are like thick and white and sticky, and they come out in these big gushing spurts."

"Hmm, sounds weird... what do boys do with it? All the sticky stuff, I mean."

"Nothing, I guess. In a tissue, down the drain, whatever to get rid of it..." Not that I have any personal experience there - I guess there is one benefit to dry heaves after all.

Dee looks disappointed as she trails a finger through a few drops of her own clear orgasmic juices splashed on her thigh. "Oh, that's too bad. What's supposed to happen with it?"

I swallow hard and make a weird croaking sound, but can't seem to form any words. This conversation is just too bizarre!

Chloe giggles at my obvious discomfort. "Dee, my dear... a boy's supposed to put his penis inside a girl's cunny and move it in and out so they both get their tingles, and then that's when the boy's sperms come out and squirt into the girl's belly."

Dee looks up at her big sister, clearly shocked by this description. "Oh! That sounds so weird! Why would a boy ever want to do that? Clee - have you ever let a boy squirt his stuff in you like that?"

Chloe smiles softly and looks down at her feet. "Mmm, nope, not yet baby girl... but I'll bet it feels real good. Don't you think, brother dear?"

Shit. My little omission might be getting away from me. "Um, yeah, Chloe. I'm sure it does, but you know I've never had a girlfriend, so it's not like I tried." What does she expect? She knows I'm a chronic loner and only 11 years old!

"Oh, really? Mmm. Guess I'm not surprised." Chloe sucks on her lower lip thoughtfully. "Y'know, Brandon... if you're gonna play naughty with me and Dee, then I suppose you could always try doing it with us. If you want."

My little stiffy lurches sharply in my pajamas - I wasn't expecting her to ever suggest going all the way, never mind suggest it so quickly!

"Uh, yeah... that would be really amazing... but like, only when you're ready... we could make a plan or something..." Like maybe in a year or two, when my sperms finally come in.

"Mmm. Why wait?"

Abruptly lightheaded and dizzy like I was when I first got out of bed, the room begins spinning around me and I brace myself against Dee's bed. "Like... right now? With you?" I squeak incredulously.

For some reason, Chloe laughs. "No, silly! I'm sure you're way too little for me - uh, young I mean. So, I was thinkin' you could do it with Dee here. First off, at least. That way I can see what it looks like, and stuff..."

I get the sneaking suspicion that my big sister's making fun of me, but there is an offer of sex with a real girl on the table. My eyes snap down to my baby sister lounging comfortably on the bed; that pink slit of hers looking so wet, hot and inviting looking I could just scream. But going through with this would involve working up the courage to reveal my meager two-and-a-half inches to my own sisters - which after yesterday I've become extremely self-conscious about - not to mention proving beyond any doubt that I can't actually make that sticky cum I was talking about.

This is all happening way too fast! Maybe I can get out of it gracefully. "Uh, isn't Dee too young for sex? I wouldn't want to hurt her."

"Oh, if I could take you then I'm sure she can too!"

My eyebrows pinch together in confusion. "Uh, what are you talking about? You're like twice as big as she is."

"Well... let's just say Dee wanted to learn to play hairbrushes with me. Took over a month of us trying 'til we could make the biggest one to go all the way in!"

My heart skips a beat. "Seriously?"

"Yup! Go ahead - try it out!"

My brain begins to short circuit at all these unbelievable ideas. "Huh? Try what?"

"Dee's cunny, silly! See if you can get your dick in so you can make your cum for us."

Shocked, I look down at Dee who just smiles happily at me and spreads her legs a little wider. Even at 7 years old, my little sister looks so incredibly sexy and arousing that my heart catches in my throat.

Here she is, selflessly offering herself and I assume her virginity to me without a second thought. Or, does she just do whatever her big sister tells her to do?

Either way, I could pull my pajamas off right now, jump on her bed, and experience sex with a willing girl for the very first time. Neither of us would be virgins any longer, and that's bound to make me way more popular at school. But what happens when Dee and Chloe learn I can't make any sperms? They'd be disappointed, and I'd just be a crummy liar.

Dee pouts. "Whatsa matter, Branny? You don't wanna try with me?"

What I actually want to do is rush outta here and empty my bladder to hopefully get rid of this throbbing stiffy, before I go and do something stupid with it.

Oh wait! Maybe that's the ticket - maybe I could go through with all this after all, if only I can make myself pee a little inside Dee. That way I could claim my cum was merely thin today, like theirs. That would work if they don't look too closely, wouldn't it?

Without warning, my pajama bottoms are suddenly yanked down to my ankles - somehow Chloe snuck up on me while I was lost in thought!

"Oh god, Dee, look at little Branny!" she giggles. "Isn't he just so cute?"

Dee props herself on an elbow to look at my naked bottom half. I feel like I should be covering my erect sex from her young and innocent eyes, but hold back since it seems only fair that she get to look after everything I've already seen of hers - plus, she's probably not so innocent.

"Oh wow!" gasps Dee. "I've never seen Branny with his willy all hard like that! But, uh, it's like a lot smaller than your big brush, Clee..."

I can feel my face blushing red at their appraisal. That freaky blonde kid was right - I don't even impress my 7-year-old sister. Staring down at my hard penis sticking straight out in front of me, I want to yell out at them, I'm perfectly normal for my age, damnit!

"Yeah, well remember, Dee... Branny hasn't hit his growth spurt yet. It'll get bigger, just like my stupid slow boobs will too. Anyways baby girl, take those silly bottoms off and lift your legs up, like when you're waiting for me to lick you..."

Dee obediently lifts her legs and pulls her thighs up beside her chest, elevating her crotch off the bed. Hooking her knees under her shoulders, she places both hands on the sides of her ass and kicks her feet loosely in the air, looking up at me with those pleading doe eyes.

Holy shit, does she look hot! Dee's spread her puffy little pussy so wide, I can see everything from the tiny pink nub of what I only recently learned must be her "clit", to the dark speck of her bulging peehole, to the reddish oval of her perfectly crinkled asshole - which even seems to be winking at me! Even with zero experience my raging stiffy instinctively knows what it wants, and bounces up and down on its own accord.

"So c'mon, Branny... you say you wanna play with us, so play already!"

Well... if my big sister insists!

Leaving my pajama bottoms in a heap on the floor, I hop on the bed and immediately dive down and push my head between Dee's legs, swiping my tongue from the rough creases of her asshole, over her gaping wet pussy hole, and all along the smooth pink skin lining her slit. Her flesh feels soft and smooth like nothing I've felt on my tongue before, and she tastes absolutely delicious - sweet like strawberries, and a little sharp like green apples.

Dee giggles and fidgets as I continue licking her over and over again, pushing the tip of my tongue just into her little hole and relishing the amazing new tastes and sensations. "No, Branny! Clee already did that earlier! Now I wanna see how boys make sperms. Do what Clee said!"

Well... if my little sister insists!

I'm not sure the best way to do this, so first I try to kneel close to her ass and press my dick into her waiting pussy. But the position's too awkward, and my penis is so short I can't even make it reach far enough.

Chloe suddenly slaps me across the ass. "No, you doof! Lie on top of her and get your dick lined up with her hole."

Climbing up on Dee, I straddle her body with my hands planted on the mattress on either side of her chest, and lower my crotch until I feel my little stiffy touch something hot and moist. Dropping down eagerly, I bang my hips clumsily against hers, sliding my penis up and down something that feels nothing short of incredible.

Oh god, sex with a girl feels amazing! Why aren't people doing this all the time?!

Chloe snorts in disdain. "Oh geez, you two are just useless! It's not even close to going in!"

The bed frame creaks as Chloe climbs on the mattress with us, and I feel the warmth of her bare skin brush between my legs. Then, something pushes past my ball sack, and all of a sudden three fingers wrap around my little erection and pull me away from what feels so good.

"Here, move up a bit," she commands.

I lift my ass and Chloe bends my penis upwards, directing the tip against something decidedly hotter and wetter than before.

"There you go - now push!" she exclaims.

I shove my hips against Dee, and in the blink of an eye my rock hard penis sinks all the way into the hottest, tightest, absolutely wettest place ever. The closest thing I can compare it to is pushing my finger in my own ass, but like a zillion times better!

"Oh my god!" I groan weakly, pinching my eyes closed and shuddering uncontrollably; barely able to cope with the overwhelmingly good sensations flooding my brain.

"Mmm, you like that hot cunny, little brother?" purrs Chloe as she toys gently with my diminutive balls. "I've never actually seen a boy and girl do it before in person. It looks so hot... damn, Dee - you're making me super jealous!" Then, she slaps my ass and I jump in surprise. "Now hurry up and move your dick in and out so we can see what happens!"

I must be the luckiest boy alive! I resume the same humping motions as before, only now they're accompanied by the indescribably amazing sensations of my penis sliding in and out of my little sister's immature pussy. I never imagined anything could feel like this!

I thrust five, ten, fifteen times, gradually increasing my speed with the guidance of my big sister's hand on my ass. I revel in the pleasure of my groin squashing into the soft bulges of Dee's puffy pussy and the way my hips force her thighs to spread apart with every lunge... and become completely entranced with how her pussy has all these fine ridges inside that stroke me better than my fist ever did, and the way her inner muscles seem to squeeze down to hold me in whenever I pull out. I never want this experience to end!

Occasionally I slip out of the radiant heat of my little sister's sex, but Chloe's hand is waiting right by our union, ready to push me back inside heaven. I think Dee might be leaking juices or something, because the skin of my groin begins sticking to her pussy and making these wet smacking sounds every time we bang together. I force my eyes open to see how she's doing, and find her eyes still closed... with the tip of her tongue sticking out between her lips, like she does when she's concentrating intently on something.

By now, the tense, aching feeling of an orgasm is building quickly. As I approach thirty unskilled thrusts and my surroundings begin to fade away from my awareness, I realize that the pleasurable sensations of sex are just too much for me to handle.

I'm nearly there - like seconds away!

"Oh man, I think it's gonna happen!" I groan, urgently whacking my groin into my baby sister.

"I'm ready for you!" exclaims Dee excitedly, the anticipation etched on her bright face - she wants this almost as much as me!

"Oh, oh, oh, oh!" I whimper as my orgasm continues to build beyond anything I've experienced. My abdominal muscles tighten to the point of agony; my energy and awareness centered entirely on my penis in my sister's pussy and the fiery electric shocks shooting deep into my groin. I begin to panic at not reach my peak, worrying that I'm doing something wrong - I can't take this torment much longer!

Just then, I remember that I'm going to need to make myself pee if I want to fool Dee and Chloe into thinking I spermed. Clenching my jaw and gathering my last reserves of strength, I push my penis as deep into my sister's pussy as I can and hold it there, straining harder than I've ever strained before to make myself urinate.

Must... pee... in Dee!

"That's it Branny - squirt your cum in Dee!"

It really doesn't seem like peeing when I'm hard is going to work, but then out of nowhere Chloe grabs my balls and squeezes them so hard, the air rushes from my lungs and glowing white sparks twinkle like fireworks in my vision. Jerking forwards so hard I shove Dee a half foot along the bed, the sudden burst of pain shoves my teetering body over the brink and into what can only be described as the most powerful orgasm of my young life.

I grunt loudly as compounding waves of ecstasy rush through my body, and just as my penis heaves inside a girl for the very first time, Chloe does something else completely unexpected: she pushes her finger in my asshole.

It feels like my dick literally explodes inside Dee with mammoth, whole-body convulsions that hurt entirely as much as they feel good. The uncontrollable spasms come one after the other for what seems like an eternity, and even though I don't know if I'm actually peeing or not, it feels like thick, molten lava is flowing through my dick with each blinding wave of sexual ecstasy.

Thirty mind-blowing seconds later, my orgasm peters out and I collapse on Dee's naked body, panting like I've just run a marathon. Within seconds, my little stiffy wilts and slips out her pussy. The finger in my ass is gone, when exactly I don't know.

"Hey, get off me, I wanna see!" complains Dee, pinned under my weight. With barely any energy left, I roll onto my back and nearly fall off the narrow bed in the process. Dee unfolds her legs and bolts upright to look between her thighs.

"Where is it, Clee? Where's Branny's sperms? I can't see them!"

Frowning, I turn my head away from my sisters and stare nervously at the closet door beside the bed. I guess I wasn't able to pee after all... so she can't see them because there's none to be found.

"Try squeezing your cunny, baby girl. Like when you were trying to push out the ping pong balls."

I hear Dee straining, and seconds later there comes a rude sputtering noise from somewhere between her legs.

"Oh look! There it is! Oh wow, Branny! Look at what you did in my cunny!"

Surprised by this result more than anyone, I sit up and cautiously peek at Dee's little pussy - where I find a veritable river of clumpy white goo draining from her inflamed 7-year-old hole and puddling on the rainbow bed sheets.

What the hell? Is that stuff mine?

Chloe whistles. "Woo - little bro, that's really some impressive kinda load there! I think I might have to let you try with me after all!"

Woah - I can't believe it! Where the hell did all that cum come from? Sure, it doesn't look like anywhere near as much as the blonde boy made yesterday, but it's infinitely more than the blanks I've been shooting up to now!

Dee eagerly dips a couple fingers in the sticky pool and pops them in her mouth. "Oh Clee! It tastes super!"

Really? Yesterday I thought the blonde boy's cum was kinda salty and bitter - although I guess mine could always be different. Regardless, Dee clearly likes it as she proceeds to collect the rest of my spilled cum with both hands, gobbling it down like it's some sort of delicious treat.

Seeing the puddle vanish in mere seconds, Chloe pouts. "Well thanks a lot, Dee - you didn't save any for me! Push some more out so I can try too."

Dee slams her legs shut and crosses her arms. "No! It's mine, an' I wanna keep it! My cunny feels nice an' nifty, like it's all hot an' squishy an' tingly."

"C'mon... you can always get Branny to make you some more later. Let me try."

"No! I said it's mine!"

Just then, I hear a loud bang in an adjacent room and we all freeze, turning to look at the wall to our left.

Shit - that's our parent's bedroom! We wait for a few seconds in total silence, barely daring to breathe. Then, there comes another noise - a dresser drawer being closed.

Dang it, mom and dad are getting up extra early today! Oh no - it must be unpacking day!

The three of us immediately scramble, Chloe picking up her discarded nightie from a dresser top, Dee clumsily yanking up the pink bottoms over her swollen cum-leaking pussy, while I snatch my damp pajamas from the floor and scurry naked out the door and back to my bedroom to get dressed for the day.

The rest of Saturday is spent unpacking a seemingly endless series of boxes, so me and my sisters never get a moment away from my parents to do anything else... naughty. For the first half of the morning, I'm floating on a cloud of blissful contentedness after having my first real sex with a girl and losing my virginity, even if it was to my own little sister, not to mention making my first-ever sperms - something I'm as proud of as I am mystified.

And yet by lunch, what happened this morning doesn't feel like nearly enough. Everything was over so fast - hell, I didn't even get to touch Chloe! Now that I know how good sex can be, I want to have so much more!

I'm achingly hard all day long as I watch my two sisters bum around in their skimpy at-home clothes, bending over and reaching up in unintentionally provocative ways. I never before noticed how Dee's tights grossly exaggerate the deep cleft of her pussy, or how Chloe's stunning ass sways side-to-side as she walks. No wonder they put her on the junior high cheerleading squad yesterday, even though it's so late in the school year!

Originally I'd planned on sneaking into Dee's bedroom after our parents had gone to bed, to see if I could talk her into doing it with me once more... but by the time nine o'clock rolls around, I'm too zonked from all the physical work to even think of anything as energetic as sex, and fall asleep the moment my head hits the pillow.

There's always tomorrow!

Except that come Sunday morning, I wake feeling quite literally like death warmed over. The strange burning sensation in my throat and stomach has returned stronger than before, and it feels like my entire body is on fire. I know I have a fever, because every one of my joints and muscles are sore and aching, and it's impossible to think straight. Did I end up catching the flu off that horny blonde kid? Now that would serve me right...

Weak and miserable, I'm thankful my parents don't make us unpack anything today and keep to myself in my bedroom, putting on a brave face whenever I come out for meals. Since I've been so broody and distant lately, my parents don't think anything of my changed behavior.

By the time bedtime rolls around, I really feel like I'm dying. Stabbing electric pains are shooting all through my insides, everything from my ears to my feet and even my damn dick is burning hot and painful to the touch, but something keeps me from telling any of this to my parents. I crawl into bed early, tossing and turning for hours before finally drifting off to sleep... but throughout the night I'm tormented by fevered nightmares that loop endlessly in my brain.

The next thing I know, the alarm clock's buzzing angrily on my nightstand. Rolling over with a weary groan, it reads 6:45 AM. It's Monday... and time to get up for school. I groan unhappily and press my head into the soft pillow. There's no possible way I can go to school with how miserable I felt last night!

Rolling onto my back, I yawn and stretch my arms and legs... and as I become gradually more alert, I discover that I don't actually feel all that bad. In fact, I feel surprisingly good!

Kicking away the covers, I slide my legs off the bed and sit there for a minute. There's no fever... no burning... no aches or pains. I'm still tired, but otherwise it seems like I'm back to normal. Thank goodness for that - although if I did have to get the 24-hour bug, then why couldn't it have been on a school day instead of having it wreck my weekend?

Sensing an urgency in both my bowels and bladder, I jump up and shuffle out my bedroom door to use the bathroom. Idly, I wonder if Dee and Chloe are up for school yet - it's too bad there's not enough time for us to have some naughty fun before school! I might have to become an early riser.

Without turning on the bathroom lights, I drop my pajama bottoms, plonk myself down on the toilet, relax... and let my urine flow.

A few seconds later, I feel wetness around the soles of my feet. Confused, I move them... and determine that a hot puddle of urine is rapidly forming around the base of the toilet. Unable to stop my flow once it's started, I lean forwards to make sure my little dick isn't accidentally peeing through the crack under the seat, and am abruptly hit by a hot spray that soaks the back of my calf.

Still drowsy and completely confused as to how my pee could possibly be reaching all the way to my leg, I stick my hand down my crotch to adjust my aim, and unexpectedly find something blocking my way. It's warm, perfectly smooth, exceptionally thick... and so very long, it's draped clear over the front of the toilet seat.

It seems... like it's attached to me.

"Holy shit!"
