Leah was three fingers deep in her own cunt, stretched back on the unmade bed, her swollen belly rising like a pale hill under the thin tank top she’d yanked up over her tits. The house was quiet except for her own slick, squelching rhythm, the wet noise of a horny pregnant woman with nothing better to do on a Thursday afternoon. Her clit was hard as a pebble under the pad of her thumb, her thighs glazed with slick, and the pressure low in her gut was just starting to coil into something useful when the front door banged open and her sister’s voice cut through the house like a blade.
“Leah! The door wasn’t even locked. You’re lucky I’m not some random pervert.”
Lynn didn’t knock. She never did. Leah heard boots in the hallway, then the bedroom door swung wide. She didn’t even try to cover herself — she couldn’t, not really, with her fingers still buried knuckle-deep and her other hand trembling against the top of her mound. Lynn stood in the doorway, one hip cocked, phone already in her hand.
“Christ, look at you,” Lynn said, and there was no shock in her voice, only that familiar edge of disgust that somehow always made Leah’s pulse jump. “Pregnant and still can’t keep your hand out of your slutty cunt. Is that all you do now? Lie here and stuff yourself like a cheap whore?”
Leah’s face went hot, but her pussy clenched around her own fingers. She should have been ashamed. Instead she spread her legs wider, letting her sister see everything — the dark pink slit, the shine of her juices, the way her pulse beat visibly in her swollen clit.
“I was just—” Leah started.
“Shut up.” Lynn crossed the room, thumb gliding across her phone screen. A small red dot appeared in the corner. “You want to act like a whore, I’ll treat you like one.” She climbed onto the bed, planted one knee between Leah’s spread legs, and swung her other leg over Leah’s face, her black denim skirt riding up to show the damp gusset of her panties. “Go on. Since you’re so fucking hungry for it. Lick.”
Leah’s mouth was already watering. She lifted her head, nosed against the cotton, inhaled the hot, briny smell of her sister’s cunt. “Lynn, I—”
A hand fisted in her hair, yanking her up until her lips smeared against the wet fabric. “I said lick, you dumb pregnant slut. Don’t make me repeat myself.”
So Leah licked. She dragged her tongue up the soaked cotton, felt the shape of Lynn’s lips through the fabric, the hard nub of her clit pressing against her tongue’s tip. Lynn’s hips rolled down, grinding against her face, and Leah moaned into the heat of it, her own fingers forgotten, her cunt still pulsing, still dripping onto the sheets.
“Getting off on this, aren’t you?” Lynn’s voice had gone thick, but the cruelty in it only sharpened. “Degenerate. Licking your own sister’s pussy while my phone gets every second of it. You want to come so bad you can’t even breathe thinking about it.” She pulled the panties to the side, and then it was bare flesh against Leah’s tongue — the slick, pink folds, the swollen bud, the familiar, forbidden taste of her own blood. “Put that pretty mouth to work. Earn it.”
Lynn filmed everything. She found the angle, held the phone steady, narrated as if the camera was her only real audience. “Look at this needy little bitch. Sobbing into my cunt like it’s the only meal she’ll get.” She ground down harder, smearing herself across Leah’s open, gasping mouth. “You want more, don’t you? Want my strap on? Want me to fuck that used-up hole until you scream?”
Leah nodded, her whole body shaking, but Lynn just laughed. “Say it. Beg for it, you pathetic whore. Tell me how much you need your own sister’s cock inside you.”
The phone hovered close, catching every tear and every needy moan. Leah’s hand found her own clit, her fingers slipping through the mess, desperate to ease the swollen ache. “Please, Lynn,” she gasped, her mouth shining with her sister’s juices. “I need it. I need you to fuck me. Please— please fuck my pussy with your strap-on. I’ll do anything. Please.”
Lynn moved fast, unzipping her pants, reaching into her purse and pulling out a huge black silicone cock, slick with lube, thick and unforgiving in the lamplight. She rolled the harness over her hips with practiced ease, the leather creaking as she buckled it snug. Leah watched from the mattress, knees fallen open, chest heaving, fingers still working her clit in slow, desperate circles.
Lynn crawled onto the bed, positioning herself between Leah’s thighs. She grabbed Leah’s wrist and pulled her hand away, pinning it to the sheet. “Mouth first,” she said, tapping the strap with one finger. “Then I’ll fill that hole.”
Leah didn’t hesitate. She rose on her elbows, leaned in, and took the silicone head between her lips, tongue swirling over the smooth crown, tasting the faint musk of lube and leather. Her eyes stayed locked on Lynn’s the whole time, glassy and wet.
Lynn held her there for a long moment, letting her savor it, then pulled back. “On your back. Spread for me.”
Leah obeyed, lying flat, legs hooked wide, heels finding the edge of the mattress. The slick mess between her thighs glistened, her body trembling in anticipation.
Lynn pressed the tip to her entrance, slow, teasing. “Look at me when I take you.”
The first push sank deep, and Leah’s breath caught in a shuddering cry. The phone tilted down, capturing everything: the stretch, the wet sound, the way Leah’s mouth fell open on a silent scream. Lynn began to move, slow and deliberate, then faster, finding a rhythm that made Leah’s hips buck up to meet her.
Lynn pulled out just far enough to make Leah gasp at the loss, then her hands clamped down on Leah’s hips, fingers digging into the soft swell of her ass. “Turn over,” she said, and the word came out soft, almost sweet, the way she always sounded right before she did something unforgivable. “On your belly. Now.”
Leah’s body obeyed before her mind caught up. She rolled, the weight of her pregnant belly pressing into the mattress, and Lynn was already on her, yanking her hips up, forcing her onto her knees with her face shoved into the sheets. The phone clattered against the nightstand, propped there, still recording, Lynn’s hands free now, both of them gripping Leah’s ass, spreading her open to the lamplight.
“Look at that,” Lynn murmured. “Dripping down your thighs, and I haven’t even let you come yet. You’re pathetic, Leah. Absolutely fucking ruined.”
Leah whimpered into the sheets, her fingers twisting in the fabric. “Please,”
“Please what?” Lynn’s breath was hot against the back of her neck. “Please fuck you from behind like the cheap little whore you are?”
“Yes. God, yes. Please.”
Lynn laughed, low and private, the sound curling through the room like smoke. Then she slammed in.
