Humanity's oldest pasttime: making creampies.

A loud slap and a louder gasp resound through the room as Matt drives himself into Nicole from tip to base. He bottoms out again and again, rocking her body and drawing ever louder cries of pleasure from her.

"Oh fuck, cum in me!" your sister begs. "Cum, Matt, please cum in me! AHH!"

"Ask and you shall receive, my little protégé," Sarah croons as she plays with Nicole's swollen clit. "Fill her all the way up, darling, 'til she can't hold any more."

Matt groans in effort. He spits out a stray bead of sweat between his lips. "Oh, holy fuck. Patience is a virtue, you know."

"CUM! PLEASE I NEED YOU! CUM IN MEEE!"

"Holy shit," Miranda remarks. She tears her eyes away for a second to look at you. "For your sake I hope she doesn't bring guys home."

You shrug. "I mean, it's fuckin' new to me."

"Haaaah!" Matt's thrusts become faster, harder, almost violent as he pushes himself to his limit. "I'm cumming, Nicole! I'm cumming!"

"YESYESYEEEEEAAAAA!"

Matt bottoms out inside of her, then after a couple of seconds humps her again, and again, and again. Her tits jiggle and her tongue lols as thick semen fills her core. Sarah grins, taking hold of Nicole's breast and massaging it firmly, while her other hand enjoys the feeling of her boyfriend's cock slipping in and out of her protégé.

"Your sister is gonna make the best little fuck-buddy, John," she says dreamily.

"Whatever you say," you mumble. Nicole's glistening face gradually un-contorts, resting comfortably in the afterglow of ecstasy. She locks eyes with you, looking blankly for a moment, then giggling. You give her a weak thumbs-up and smile back.

Miranda takes hold of the back of your head and pulls you down for a kiss. She giggles adorably as you suck on her tongue. "John," she says against your lips.

"Yeah?" You feel her hips moving back and forth across yours, and your cock twitches inside her.

"Can we go again right away?"

"Um, yeah." Your body's not quite ready yet, but you can fix that. "You're not full enough yet? Need me to cum inside you again?"

She only smiles and nods, pressing herself snuggly against you.

Sarah lays a hard slap on Miranda's ass. "You kidding? This little slut won't be satisfied until her womb is stuffed to bursting."

"Her...wha? Sarah, what-"

"It's a fetish," Matt explains. "Our fetish, but we're usually alone. Sorry if-"

Nicole steals a kiss before he can finish. He leans in enthusiastically, meeting her tongue with his own. "Cum in my womb Matt," she demands. "Fuck me senseless and cum in my pussy and fill me up until I get pregnant."

He blinks. "As I was saying. Sorry if it gets weird."

"Little late, but thanks." You're frozen with a blank expression on your face.

Your sister smirks. "How was that?"

"You'll get there," Sarah encourages. "Do you talk dirty a lot?"

"No. I have more sex than John, but that's not saying much."

You scoff. "Harsh."

Sarah gives Nicole's nipple a little squeeze. "You'll get plenty of practice from now on, my sweet concubine. You can spend all day every day begging for Matt's cum until both our bellies are big and round."

"Get a room," you say. A sting of regret hits as you as you wonder if that was too rude, but Sarah brushes it off.

"John, you can take our bed if you need to, but Nicole is getting creamed on the floor tonight." She runs her finger along your sister's labia, finding a lot of quim and a bit of Matt's cum. "I'd really prefer if you two stayed," she coos, gently inserting the mixture into Nicole's mouth. The younger girl suckles hungrily, grabbing Sarah's wrist and wiggling her hips against Matt.

Miranda moans excitedly as your cock throbs inside her. "Feels like you're ready," she teases.

"Fuck yeah, I am." You start to move, slowly thrusting in and out of her.

"Hold on," she says. "I want to ride you."

"Oh. Perfect! I wanted your tits in my face."

You pull out and sit upright, letting Miranda climb on top of you. Meanwhile, Sarah gives her own instructions to her partners.

"On all fours, baby. You've done doggy, haven't you? Matt, you're going to pound the shit out of her. Use her like a fleshlight." She brushes a strand of Nicole's hair behind her ear. "You're going to try your best to eat my pussy. Don't worry about making me cum. You've never fucked a girl before, right? You can be as messy as you need to be."

"Mm-hm," is the only reply as Nicole wiggles her ass in the air. Matt catches it with one hand and uses the other to quickly insert himself. As directed, he begins drilling her at a bold pace, her slim body shaking with every thrust. Sarah spreads her legs and slides beneath Nicole, gently pushing her head down until lips meet clit.

You can't tear your eyes away from the sight, but you focus enough to hold your dick straight while Miranda sinks down on top of you. A shock of pleasure jolts your entire body and hers. You grip her ass and help her lift herself up to the tip of your cock, then drop her back down onto your full length. Your mouth almost subconsciously closes on her nipple, licking feverishly and soaking it with saliva. She shivers against your touch, adopting a steady pace bouncing in your lap. Your cum sloshes inside her, dripping down to pool between your legs.

Nicole yelps as Matt hits a sensative spot. Sarah applies just a little extra pressure to keep her toy working on her pussy. Nicole's tongue lashes wildly across her labia, then digs deep into the older girl's hole.

"You're doing great, baby," Sarah coos. "Don't let up, Matt. Your only job is to cum. Creampie her beautiful little pussy in front of her big brother."

He leans down over Nicole's head, grabbing her tits for support. "She's pretty full already." His breathing is loud, his voice husky. "Can you fit it all inside you, Nicole?"

"All of it!" she squeals. Sarah forces her back to work quickly. Both girls moan shamelessly as their vigorous threesome progresses.

Your cock twitches restlessly against Miranda's tight walls. "Oh, fuck," she sputters. Her eyes are locked on the trio across the room, totally enthralled.

"Whatcha thinking about?" you grunt. You lift her a bit more forcefully, slamming her ass down onto you.

"Nicole's a real pro. Mmm...!"

"Anyone can lay face-down in pussy and get dicked into oblivion."

"Hey! That's not true!" Sarah admonishes. "Most girls can't do what she can. Or at least they don't."

You wave her away. "I'm just playing, just playing. Don't want her to get a big head."

Nicole braces against the floor with one hand and flips you off with the other. A moment later she falls forward as Matt drives himself deep inside her, taking a second to breathe each time he sends her reeling.

"I'm getting close," he says, withdrawing his cock to the head and forcing it right back in.

"Yes, yes," Nicole pants. "I'm ready. Cum in me. Please cum in me!" Sarah pushes her head back into place.

Miranda feels your lips tugging on her nipple and looks down at you. "How about you, John?"

You give her tit an exaggerated wet smooch. "I can go longer than Matt," you promise.

"Easy to say that now!" Matt retorts. He shifts his legs a bit, getting ready for the final sprint. "Let's do this."

His thrusts are fast and hard and deep, pushing Nicole forward against his girlfriend's pussy. Both girls moan louder and louder, one in control and the other losing it completely. Sarah's legs curl over Nicole's back, firmly holding her in place.

Not wanting to get too distracted, you double your efforts with Miranda. You ignore the ache arising in your arms as you slam her onto your cock with as much **** as you can. She finally looks down from the show and speaks to your face. "That's perfect! Just like that!"

You're not sure how long that's going to last, but you nod your head and keep going, driven by the need to out-fuck Matt. Your sister's noisy orgasm spurs you on, intent to get the same reaction from Miranda.

"Ah fuck!" Matt gasps. "I'm gonna cum! I'm gonna cum!"

Sarah clutches Nicole tighter. "Yes! Cum in her tight little pussy! Cum, baby. Cum for both of us!"

The volume in the room reaches a new height between Sarah's cheering, Nicole's squealing, and Matt's groaning. He rams into her and remains buried deep in her flesh for a second, then repeats the motion, then again, and again. Her head lies limp against Sarah's pussy, focused on nothing but her own pleasure. When Matt finally finishes after the longest thirty seconds of your life, he rests inside her and leans hard on the floor, gasping for air.

"Fuck!" Miranda moans, shuddering on your cock. "Oh, fucking God!"

You're damn near exhausted and very ready to bust. "I'm gonna roll you," you say.

"Uh?"

"Lay down." With one hand on the rug and one on the small of her back, you roll your bodies over until she's on her back. Now you've got a perfect view of Sarah cradling your sister between her thighs as a white droplet streams down Nicole's leg. You're going to put the same fucked-silly expression on Miranda's face. "I'm gonna fuck you like crazy until I cum," you tell her. "You're gonna be twice as full as Nicole, yeah?"

Her pussy squeezes you in response. You plant your tongue against her nipple and suck hard on her tit one more time to steel yourself for the final stretch. Then, you begin to drill her. Faster and harder than the first time. Faster and harder than Matt. Faster and harder than any porn you've ever watched. ...Okay, maybe not that last one, but damn close at least. Your body rocks hers over and over again, pounding her into the soft floor and keeping the room abuzz with the sound of slapping flesh and swishing cum.

"Yes, John!" Sarah shouts. "Knock her up right here on our floor!" She strokes Nicole's hair, looking down at her with adoration. "Just imagine! Two cute little babies who owe it all to my party!"

"Chill, Sarah!" you reply. Your voice is strained with effort. You reposition your hands on Miranda's thighs and squeeze, pressing even deeper into her.

"Fine. One little baby, and one pussy on the pill. You still better cum buckets inside!"

You roll your eyes. "You bet. ...Gah!" Without warning, Miranda's pussy spasms, her whole body tightening from an intense orgasm. As she massages your cock, you refocus on pounding her with everything you've got, knowing you can't last much longer like this. You lean down over her tightly shut eyes and delicately kiss her forehead. She releases a long, loud moan, absently running her hand up your arm. She's reaching higher on your body, maybe your pecs or your back, but she can't raise her arm that high as pleasure paralyzes her. "I'm gonna cum," you say. "Ngh... I'm gonna cum buckets inside you."

Miranda gives no reply, but Sarah and Matt cheer. Even Nicole manages to shake off her stupor and turns to face you with a wide grin. She slowly leans her body forward, allowing Matt's cock to glide out of her. A dollop of semen falls from her violated pussy to the carpet below.

You aren't fully prepared for the first orgasmic jolt that runs through you, and you barely register the accompanying jet of cum as it rockets into Miranda. You stuff yourself as deep in as you can, wiggling your hips just enough to keep pressure on your cock. Your body trembles, so much that you can barely hold yourself up. Her pussy squeezes and squeezes, wringing you dry and devouring every drop. Your body gives out before your dick, and you collapse in a sweating, gasping heap on top of her as the last of your seed dribbles out. A new well of thick cum more than replaces the first creampie you churned into froth.

"Two cute little babies," Sarah marvels. She caresses Nicole's chin and kisses her, but the younger girl's lips are limp. Sarah looks at her through big, caring eyes. "Tired?"

"Yeah."

"That's okay. We're gonna sleep right here tonight. Matt, help me gather up all the blankets."

He groans quietly. "I'm tired too."

"Oh, poor baby. Our guests are gonna pass out on the floor, c'mon."

With a long sigh and some loud stretching, he picks himself up off the floor. Nicole watches through half-open eyes. "Matt."

"Mm?"

"Thank you for trying to make me pregnant."

"Fucking hell," you mutter.

He chuckles. "You're welcome. Thanks for letting me."

"I mean it," she says dreamily. "I hope I really am."

"I mean it too, baby," Sarah assures her. "Hurry up, Matt."

Over the next few mintues, your friends gather blankets and pillows from the couch, closet, and their bedroom down the hall, laying them all out on the living room floor. The resulting pile is thick and soft, and just wide enough for all five of you. You finally pull your sticky cock out from Miranda and help her into the center of the makeshift bed. Nicole curls up next to her, smiling at you before laying her head beside your girlfriend. Drowsy as you are, you barely register surprise when arms wrap around you from behind before you lay down.

"Can I be the big spoon?" Sarah asks.

"...What?"

She nuzzles into your neck. "I wanna spoon with you tonight. I get you, you get Miranda, Matt gets Nicole, and the little spoons can tongue-fuck each other when they wake up."

You can barely understand a word she's saying, but her tits feel good on your back. "'Kay."

"Yay!" She snuggles against you as you lay down, squishing her boobs and pressing her thighs firm against your ass. You hold Miranda more gently, fitting loosely into your place over her. Matt does the same behind your sister, fast asleep.

Good time for some shuteye, you think. And all things considered, a pretty fantastic day.

"Great party, Sarah," you mumble. You don't hear her response, already drifting off to the best sleep of your life.
