What happens next?
Gwen gets knocked up
You sit at the kitchen table with Gwen, forcing small talk about her classes, her roommates, anything to fill the tense silence while the minutes crawl by. James sits opposite her, grip tight on his mug, eyes fixed on her petite body like a predator barely leashed. Every time Gwen shifts in her seat, her cropped tank rides higher, exposing more of her flat stomach; every time she lifts the mug to her full lips, her small breasts press against the thin fabric. James’s breathing is shallow, his thigh tense under the table where your foot brushes his—he’s seconds away from snapping.
Ten minutes in, Gwen fans herself again. “Why is it so hot in here?” she mutters, tugging at her tank. Her cheeks are flushed now, a deeper pink spreading down her neck.
Fifteen minutes. She squirms openly, thighs pressing together, a soft whimper escaping as she sets the mug down. Her eyes glaze, pupils blown wide, and when she looks at James it’s no longer with suspicion—it’s raw, **** hunger.
“James…” she breathes, voice small and needy. “I feel… I feel weird. I need—God, I don’t know what I need, but I need it so bad.”
The Frenzy Tab has hit.
James is on his feet in an instant, chair scraping back. He rounds the table, pulls Gwen up by her tiny waist, and she melts against him, arms wrapping around his neck as she presses her whole body to his. Her hips grind instinctively against the hard bulge in his sweatpants.
“Bedroom,” he growls, voice rough with barely-contained lust. “Now.”
Gwen nods frantically, already panting. “Yes. Please. Bedroom.”
You follow them down the hall, pulse thundering, hand slipping under your dress to touch yourself as you watch. You stay in the gap of the door, fingers circling your clit, unable to look away as James takes your sister in front of you.
James lifts Gwen effortlessly—she’s so small in his arms—and deposits her on the bed. Her shorts and tank are gone in seconds, peeled off by eager hands (hers and his). She’s completely bare now: petite, perfect, skin flushed pink, small breasts heaving, nipples tight, a neat strip of hair above her slick, swollen pussy.
“Please,” she begs, spreading her legs wide without shame, fingers parting herself for him. “I need you inside me. I need you to fill me up. Breed me. Please breed me.”
James groans like he’s in pain, shoving his sweatpants down. His cock springs free—thick, heavy, already leaking—and Gwen whimpers at the sight, hips bucking off the bed.
He doesn’t wait. He climbs over her, lines up, and thrusts in with one deep stroke. Gwen cries out, back arching, tiny body stretching around him as he bottoms out. The sound is obscene—wet, ****—and James immediately sets a brutal pace, hips slamming into hers, bed creaking under the ****.
You lean against the doorframe, fingers pumping inside yourself in time with his thrusts, biting your lip to stay quiet as you watch your little sister turn into a mindless breeding slut.
They don’t stop.
James flips her onto her stomach, yanks her hips up, and takes her from behind—her small frame jolting with every thrust, face buried in the pillow as she screams for more, harder, deeper. He obliges, one hand fisted in her hair, the other gripping her narrow waist hard enough to bruise.
Then she’s on top, riding him frantically, tiny breasts bouncing as she grinds down, chasing her own release. James thrusts up to meet her, growling filthy promises—“Gonna pump you full, little girl. Gonna knock up this tight pussy. You’ll be swollen with my baby by morning.”
Gwen comes again and again, voice hoarse from screaming, body trembling, but still begging. James fills her over and over—thick, impossible loads that leak out around his cock with every thrust, painting her thighs and the sheets white. Yet he stays hard, insatiable, driven by the curse and the ****.
They go all night.
Missionary with her legs over his shoulders, folding her small body in half. Against the wall, her legs wrapped around his waist as he bounces her on his cock. On the floor when they roll off the bed, too frantic to climb back up. Spooning slow and deep in the early hours, his hand splayed over her flat belly as he rocks into her and whispers how perfect she’ll look round and pregnant.
You stay in the doorway the whole time, touching yourself through countless orgasms, watching your sister get thoroughly, relentlessly bred.
Does the night end here?
