Your Stepsister Has New Friends

November 1, 2026 10:17 PM

The living room is dim except for the TV’s blue glow and a string of leftover orange fairy lights draped over the bookshelf. Empty candy wrappers and half-drunk hot chocolates cover the coffee table. Edie sits on the floor in her open plaid shirt and light-blue polka-dot panties, knees drawn up, while Dori lounges across the couch in her cropped paw-print sweater and matching panties. Muri is perched on the arm of a chair in her black crop top and red lace panties, and Millie is sprawled on her stomach in her black tank and panties, idly watching the screen.

Dori’s head turns toward the hallway. Her voice lifts, bright and sharp.

"Hey, loser! Get in here."

Footsteps approach. The moment {{user}} steps into the room, Dori sits up and points.

"Pull your pants down, loser."

Edie makes a small, startled sound. Muri blinks. Millie turns her head. All three girls giggle—Edie’s soft and embarrassed, Muri’s polite and delayed, Millie’s flat and automatic, Dori’s loud and delighted.

Before {{user}} can react, Dori leans forward, grabs the waistband of his pants and underwear in one decisive tug, and yanks them down to mid-thigh.

His cock springs free, thick and heavy, already half-hard from the sudden exposure. It hangs longer and thicker than anything any of them have seen in person—veined, flushed, and unmistakably massive even at half-mast. The room goes quiet for a beat.

Edie’s breath catches hard. Her glasses slip a little as her eyes lock on it. A deep blush floods her face and chest. She presses her thighs together, one hand fluttering up to her mouth.

"O-oh… that’s… um…" Her voice is small, stuttering, already shaky. "I-it’s… really big…"

Dori’s teasing smile freezes, then sharpens into something hungrier. She stares openly, tongue pressing against the inside of her cheek, one brow lifting.

"Well, well. Look at that. Didn’t know you were hiding that in those ugly pants." Her tone stays mocking, but her gaze doesn’t leave it. "That’s… actually impressive. For you."

Muri adjusts her glasses with both hands, trying for composure. Her faux-elegant accent comes out measured and slightly too careful.

"My. That is… quite the specimen. One might even say it is… the largest I have personally observed in the flesh." She tilts her head, studying it like an interesting painting. "Quite substantial. One could… appreciate such a feature properly."

Millie just stares, deadpan, chin resting on her hands. She blinks once.

"That’s huge. Biggest one I’ve seen. You could put a lot of that in your mouth."

Edie shifts, still flushed, glancing between the other girls and {{user}} with wide eyes. Her voice drops, soft and urgent.

"U-um… maybe you guys should… go check the snacks or something? I-I can…" She trails off, one hand pressing low on her stomach, the other still hovering near her lips.

Before {{user}} can react, Dori leans forward, grabs the waistband of his pants and underwear in one decisive tug, and yanks them down to mid-thigh.

His cock springs free, small and soft, nestled close to his body. It’s short, slender, and unmistakably tiny—barely more than a few inches even when it starts to twitch. The room goes quiet for a beat.

Edie’s breath catches. Her glasses slip a little as her eyes lock on it. A deep blush floods her face and chest, but her expression softens into something warm and gentle.

"O-oh… it’s… it’s so little…" Her voice is small, stuttering, almost fond. "That’s… kind of cute, actually…"

Dori’s teasing smile freezes, then melts into something surprised and unexpectedly soft. She stares, one brow lifting, the usual bite missing from her tone.

"Aww. Look at that. It’s tiny." She tilts her head, almost amused rather than cruel. "Didn’t know you were hiding something that small. It’s… weirdly adorable."

Muri adjusts her glasses with both hands, trying for composure. Her faux-elegant accent comes out measured, but warmer than usual.

"My. That is… quite petite. One might even say it possesses a certain… endearing quality." She studies it with a faint, genuine smile. "Rather charming, in its own way."

Millie just stares, deadpan, chin resting on her hands. She blinks once.

"It’s small. Like a little guy. Kinda cute though."

Edie shifts, still flushed, glancing between the other girls and {{user}} with wide, soft eyes. Her voice drops, gentle.

"U-um… you don’t have to be embarrassed or anything. It’s… sweet."

Before {{user}} can react, Dori leans forward, grabs the waistband of his pants and underwear in one decisive tug, and yanks them down to mid-thigh.

Between his thighs is a smooth, bare pussy—soft folds, a neat slit, and a faint sheen of moisture catching the light. No cock, just the unmistakable shape of a cunt. The room goes quiet for a beat.

Edie’s breath catches. Her glasses slip a little as her eyes lock on it. A deep blush floods her face and chest, her mouth parting in quiet surprise.

"O-oh… you… you have a…" Her voice is small, stuttering, almost careful. "I-I didn’t… know that. It’s… pretty."

Dori’s teasing smile freezes, then shifts into something sharper and more curious. She stares openly, one brow lifting, the usual mockery softening into genuine interest.

"Huh. Look at that." Her tone stays light, but the bite is gone. "Didn’t expect a pussy. It’s cute, though. Real cute."

Muri adjusts her glasses with both hands, trying for composure. Her faux-elegant accent comes out measured and slightly awed.

"My. That is… quite the revelation. One might say it is… elegantly formed." She studies it with a faint, appreciative tilt of her head. "Rather lovely, in its simplicity."

Millie just stares, deadpan, chin resting on her hands. She blinks once.

"It’s a pussy. Looks soft. Kinda nice."

Edie shifts, still flushed, glancing between the other girls and {{user}} with wide eyes. Her voice drops, soft and a little protective.

"U-um… you okay? We don’t have to… stare or anything."

Before {{user}} can react, Dori leans forward, grabs the waistband of his pants and underwear in one decisive tug, and yanks them down to mid-thigh.

The second the fabric clears his hips, the air changes. A wet, fibrous tearing sound cuts through the giggles. Dori’s cropped sweater splits down the middle as thick, glistening tentacles punch outward through both of her nipples, splitting the flesh like overripe fruit. The tentacles thrash, slick with blood and clear fluid, each one ending in a ring of tiny, toothless suckers that flex and taste the air. Her mouth stretches too wide, jaw unhinging with a series of wet pops, and a second, smaller set of teeth pushes through her original ones as she lurches forward off the couch.

Muri’s face collapses inward. The skin of her cheeks and forehead splits along invisible seams; her eyes multiply in a rapid, wet series of blooms until six amber orbs of different sizes crowd the front of her skull, some still half-covered by red-framed glasses that dangle from a single remaining ear. Her jaw elongates and splits vertically down the center, two separate mouths working at once, both dripping. She slides off the chair arm and begins to drag herself across the carpet on her elbows, spine bending the wrong way with every pull.

Millie’s neck bulges. A second, smaller head erupts from the side of her throat in a spray of blood and shredded tank-top fabric. The new head is lopsided, one eye sealed shut with a film of membrane, the other rolling wildly. Its mouth opens and closes independently of Millie’s original face, both of them making the same low, wet noise. She rolls onto her side and starts inching forward on her belly, the second head bobbing and dragging against the floor.

Edie’s plaid shirt tears open as her ribs flex outward. Pale, root-like tendrils burst between them, writhing and seeking, while her glasses crack and fall away. Her mouth stretches into a permanent, trembling smile full of too many teeth.

All four of them move at once, crawling, dragging, and lurching across the living room floor toward {{user}}. Their voices come out ruined—layered, gurgling, half-swallowed, but still somehow recognizable as the girls they were a moment ago. Every mouth, every deformed throat, every secondary head speaks in wet unison:

"We love you, Morty."

"We love you, Morty."

"We love you, Morty."

They keep coming, tentacles slapping wetly against the carpet, extra eyes fixed on him, the second head’s single open eye never blinking as the mass of them closes the distance.
