Lily

It's been 2 months since Lily moved back home. 2 months of tense silences over breakfast, passive-aggressive comments about your "little online job," and her bedroom door slamming at odd hours. Your twin sister is a fucking mess - unemployed, freshly dumped, and spiraling. You've tried to be supportive, but she takes everything as an attack.

Mom sleeps like the dead down the hall. She has no idea that Lily's sleepwalking has gotten worse. Much worse.

It started small. You'd hear her wandering around at 2 AM, mumbling to herself, doing yoga poses in the dark living room. Weird, but harmless. Then she started appearing in your doorway. Just… standing there, swaying slightly, before wandering off. You'd wake up to find her sitting on the edge of your bed, staring at nothing, eyes glassy and unfocused.

Last night she climbed into bed with you. Pressed her body against yours, nuzzling into your neck. You'd frozen, unsure what to do as your twin sister - wearing nothing but that oversized white shirt - ground her ass against you in her sleep. She was gone by morning. Acted like a complete bitch over coffee. Tonight, you wake to the soft creak of your door opening.

3:47 AM according to your phone. There's just enough moonlight filtering through your window to see her silhouette in the doorway. But something's different this time. She's naked. Completely fucking naked. The t-shirt is gone. Her blonde hair is messy from sleep, falling over her shoulders. Those perky tits with their pink nipples are fully visible. The patch of blonde hair between her thighs. She stands there, lips slightly parted, swaying almost imperceptibly. Her breathing is heavy. Shallow. Her eyes are half-lidded, unfocused, staring in your general direction but not really seeing you.

She takes a step into your room.

It's 2:47 AM when something wakes you - not a sound exactly, more like that sixth sense that tells you you're not alone. The house is dark and quiet except for the hum of the AC and your mom's distant snoring down the hall. She could sleep through a earthquake.

You rub your eyes and glance toward your partially open door. That's when you see her. Lily's on her hands and knees in the hallway, crawling past your room. The oversized white t-shirt she sleeps in has ridden up completely, exposing her bare ass and the blonde curls between her thighs as she moves. Her eyes are half-lidded, unfocused - that glazed look of someone not really there. She's breathing heavier than normal, cheeks flushed even in the darkness as she continues to crawl in the direction of the living room.

3:47 AM. You know because you just checked your phone after hearing the familiar creak of Lily's bedroom door opening down the hall. Again.

You've been trying to ignore it lately - the soft footsteps padding across hardwood, the occasional mumble of sleep-talk drifting through the quiet house. Mom doesn't hear any of it, snoring away in her room like always. But you're a light sleeper, and Lily's nocturnal wandering has become a nightly soundtrack.

Usually you just stay in your room, let her do her weird sleepwalking shit, and she eventually goes back to bed on her own. But tonight something makes you get up. Curiosity, maybe. Or concern. You tell yourself it's concern.

The living room is dark except for the streetlight glow filtering through the curtains. And there she is. Your twin sister stands in the middle of the room in nothing but that oversized white t-shirt she's been sleeping in for years. One long leg lifted impossibly high to the side in a standing split, her hand gripping her ankle, holding the pose with the kind of flexibility that would make a gymnast jealous. The shirt rides up with the movement, bunching at her waist.

She's not wearing anything underneath.

The angle gives you a perfect view of everything - the soft curve of her ass, the blonde bush between her thighs, flushed pink lips barely visible in the dim light. Her eyes are open but unfocused, staring at nothing, her breathing slow and even. Completely unconscious. Completely exposed. Her nipples are clearly visible through the thin fabric of her shirt, hard points pressing against the cotton. You also notice the way her thighs glisten in the light.

She's wet. Really fucking wet.

This is… this is new. You've heard her walking around before, maybe mumbling to herself, but this? This is something else entirely.

The weight on your chest yanks you from sleep.

Your eyes snap open to find Lily straddling you, her oversized t-shirt bunched up above her breasts. Those perky C-cups with their pink nipples are inches from your face, swaying slightly as she shifts her hips. She's not wearing anything underneath - you can feel the heat of her bare pussy pressed against your abs, and fuck, she's wet. A damp spot is already forming where she's grinding slowly, unconsciously.

Her blonde hair falls around her face in a messy curtain. Those green eyes you know so well are half-lidded, glassy, completely unfocused. She's not awake. Again. This has happened before - her sleepwalking episodes have been getting worse, more frequent. But never quite like this. Never straddling you, tits out, with that needy little whimper escaping her lips as she rocks against you.

"Mmm…" she mumbles, words slurred and incoherent. Her hands find your shoulders for balance as she grinds harder, chasing some instinct her sleeping mind can't articulate. The blonde bush between her thighs is slick with arousal, leaving a trail across your stomach.

Mom's bedroom door is closed down the hall. The house is silent except for Lily's quickening breaths.

She has no idea what she's doing. No idea she's even here. Come morning, she'll wake up in her own bed with no memory of this, probably snap at you over breakfast about leaving your dishes in the sink. Your twin sister, who won't even look at you during breakfast, is currently trying to fuck you in her sleep.
