He wants to you

Sam licks his lips hungrily as he looks you up and down, taking in every curve of your barely constrained body. "Thanks babe, I want to **** her while I fuck her pussy," he grins at Zoe before turning his full attention back to you. He reaches out a hand and tugs you closer by the waistband of your tight yoga pants until you're standing right in front of him.

"Come here sexy, let's have some fun," Sam purrs as he wraps an arm around your lower back and pulls you onto his lap so you straddle him. You can feel the prominent bulge already straining against his jeans, throbbing with anticipation.

Zoe settles cross-legged on the bed in front of them watching intently, nipples visibly hard through her thin tank top as she awaits what happens next.

Sam slides his hands up your sides and around to palm your heavy breasts, kneading the supple flesh. Your stiff nipples poke straight at him as he manhandles your breasts. "Fuck, I love your big titties," he groans before ducking his head down to smother his face in them.

"Suck on them," Zoe encourages eagerly, rubbing her own nippes while watching Sam maul you.

Sam complies immediately, latching onto one nipple and suckling greedily while pinching and rolling the other between his fingers. His hips start humping up into yours as he gets more aroused from groping your tits. Sam releases your nipple with a wet pop before immediately diving back in licking a trail up between your cleavage before wrapping his lips around one. He suckles hard as he rolls it between his teeth while kneading the other mound roughly in his palm, sending jolts straight to your core.

You moan and arch your chest into him, craving more of that intense stimulation on your sensitive nipples as you grind down onto the rigid length trapped in his jeans. Sam releases your nipple with a gasp when it's clear you're both getting carried away.

"Take off those tight pants and panties," he commands gruffly, "so I can see all of this sexy body."

You quickly shimmy out of the skintight yoga pants, baring your glistening pussy to Sam's hungry gaze. The cool air feels delicious on your overheated skin as Zoe watches eagerly from her perch on the bed.

"Damn girl, that pretty pink cunt is dripping for me already," Sam groans approvingly before giving your ass a firm smack. He stands and quickly sheds his own clothes, revealing an impressive erection jutting proudly towards you. Gently pushing you down onto your back on Zoe's futon, Sam settles between your spread thighs, the thick head of his cock nudging insistently at your entrance. Wrapping one large hand loosely around your slender throat, he looks into your eyes with a lustful smirk before thrusting forward hard and deep, spearing you open on his throbbing shaft.

"Oh fuck yes," Zoe moans loudly as she watches her boyfriend claim her younger sister's virgin pussy so assertively. "Fuck her harder Sam!"

Sam complies, snapping his hips faster and slamming into you balls-deep with each powerful thrust while keeping that tight grip on your neck. The tightening pressure on your neck makes your head swim deliciously as arousal floods through your veins.

"Your slutty sister feels fucking incredible," he grunts to Zoe between punishing thrusts. "This cunt is gripping me so tightly."

Zoe moans and plays with her own tits in response, loving the filthy dirty talk. The combination of Sam's deep strokes pounding into your core while his strong hand squeezes around your neck has you seeing stars.

"Yes, fuck! Harder!" Zoe cries out, rubbing herself frantically through damp panties as she watches Sam rail you brutally on her bed. Your pussy clenches needily with each thrust and the headboard slams rhythmically against the wall from his forceful fucking.

Sam leans down to capture your mouth in a messy kiss, tongue delving in to tangle with yours as he pounds into your sopping wet cunt relentlessly. Breaking away with a groan, Sam flips you over onto your hands and knees, yanking your hips back to meet his pistoning thrusts.

"Gonna fuck this pussy 'til you scream on my cock," he promises darkly while spanking your bouncing ass hard, leaving red handprints blooming across the pale skin before wrapping both of his hands around your neck from behind and squeezing tightly. Zoe watches wide-eyed, one hand buried in her panties as she masturbates fiercely to the erotic sight of Sam roughly claiming his birthday present. Your body rocks forward from the **** of Sam's powerful thrusts and his fingers tighten firmly around your slender throat. Your face is getting flushed and you realize that you can't breath at all as his fingers closed off all air.

"Play with those big tits while I rail this fuckhole," Sam commands breathlessly, spanking you again in encouragement as he jackhammers into your dripping snatch ruthlessly, chasing his release. Your pussy spasms around him rhythmically from the intense stimulation to your g-spot and clit.

"Yes baby!" Zoe calls out happily before crawling over to sit behind Sam on her knees. She reaches around to fondle and tug at Sam's heavy balls as they slap lewdly against your thighs with each forceful thrust, urging his climax closer while pinching your nipples almost painfully in encouragement.

Sam hilts deep inside you one last time before stilling balls-deep, erupting jet after jet of hot cum to paint your convulsing walls white. "Take it slut!" Zoe squeals delightedly as she continues playing with both of your sensitive erogenous zones while Sam empties his heavy load into your hungry cunt.

You try to gasp for breath, but nothing comes through and you feel yourself go lightheaded from the lack of oxygen as well as the rough doggy style sex. Your arms give way as you feel yourself about to pass out when he lets go of your throat and you begin desperately gasping for air and coughing.

Panting harshly, Sam rolls off you onto the bed, pulling a giggling and naked Zoe down to join him as his cock slipped free from your brutalized hole. You find yourself powerless next to them, thoroughly used, pussy dripping with cum as aftershocks ripple through you both. Zoe kisses you sloppily while Sam recovers behind her, already imagining what other dirty things they might get up to next.
