My Stepsister Begs for My Cock

The house was too quiet without their parents in it. Hugo sat on the edge of the couch in gray sweatpants, phone dark in his hand, listening to the kitchen clock and trying not to think about dinner. He was twenty-eight, and he still felt like a trespasser in his own living room whenever she walked through it. Their parents had married four years ago, the summer Annika turned eighteen, and he had spent every visit since then staring at safe things: the television, his plate, the door. She was twenty-two now, a college graduate who had moved back home while she hunted for an apartment, and the safe things had stopped working.

She came down the stairs in a thin tank top and panties the color of cheap wine, bare feet silent on the rug. No bra. He saw that and looked away so fast his neck hurt.

"They're gone till Sunday," Annika said. Her voice was low, the one she used when she already knew she would get what she wanted. "Mom texted from the hotel. Your dad's already asleep in the next room over there. We're alone."

"Annika." He kept his eyes on the blank TV. "Go to bed."

"I've been trying to." She stepped between his knees, close enough that he could smell her shampoo and the warmer scent under it. Her hand landed on his shoulder and stayed, thumb drawing a slow circle that had nothing innocent in it. Weeks of this. Tight clothes in the kitchen. Fingers that lingered on his wrist when she passed him a plate. "I can't sleep. I keep thinking about you. I have been thinking about you since the wedding weekend, since I was eighteen and old enough to know exactly what I wanted and too scared to say it out loud. Four years, Hugo. You felt every one of those touches."

His jaw locked. "You're my stepsister."

"I know what I am." She leaned down until her mouth was at his ear, breath hot. "I'm your twenty-two-year-old stepsister, and I have been fantasizing about your cock since I was old enough to want it and mean it. Not before. After. Every night I was legal I touched myself and said your name into the pillow so they wouldn't hear. I am done pretending." Her fingers slid to the back of his neck. "Please. Give in. I am begging you to fuck me."

He should have stood up. He should have told her no and meant it. Instead he sat there with his pulse in his throat and his hands clenched on his thighs, already losing.

"We can't," Hugo said, and his voice came out wrecked. "If they ever found out—"

"They won't." Annika sank. One second she was standing over him and the next her knees hit the rug between his feet, tank top strap sliding off one shoulder, eyes lifted and shining with something desperate. "I've wanted this too long to be careful about pride."

Her hands found the waistband of his sweatpants. He caught her wrists, not hard, just enough to stop her. The heat of her skin went straight through him.

"Annika. Stop. I'm your stepbrother. This is—"

"Forbidden. I know. That's why I'm soaked." She didn't pull free. She waited, looking up at him, and when his grip loosened she took it as the yes it almost was. She tugged the sweatpants down. He was already hardening, thick and flushed, and the sound she made when she saw him was small and filthy. "God. Look at you."

She wrapped her hand around him and stroked, slow, from base to tip, thumb smearing the wet at the head. Her eyes never left his face.

"I finger myself thinking about this," she whispered. "Two fingers, sometimes three, stuffed in my pussy while I imagine my stepbrother bending me over and using me. I come saying your name. I have for years, every year since I turned eighteen and realized I would never want anyone the way I want you. I rub my clit and pretend it's your mouth. I am so tired of pretending."

His breath hitched. His hand hovered over her hair and didn't quite land.

"Please," she said, stroking him harder, lips close enough that he felt the word on his skin. "Please fuck me. I am begging my stepbrother to put his cock in me. I want it. I want you. Say yes."

Something in him snapped clean in half. The guilt didn't leave. It just stopped mattering more than the need. He grabbed a fistful of her hair, not cruel, firm enough that her mouth fell open and her stroking hand stuttered.

"You want forbidden stepbrother cock?" His voice had gone low and mean with want. "Then you're going to take every inch of it. Every inch, Annika. You hear me?"

"Yes." She nodded against his grip, eyes wet and eager, no fear in them at all. "Yes. Give it to me. I want all of it."

"Then get up."

He hauled her to her feet and turned her toward the couch. She went willingly, palms hitting the cushion, back arching, ass tipped up in those wine-colored panties. He dragged them down her thighs and left them tangled at her knees. She was glistening, swollen, dripping onto the fabric. He ran two fingers through her and she moaned like she'd been waiting her whole adult life for exactly that.

"So wet for your stepbrother," he said, and pushed into her in one long stroke.

She cried out, high and broken, and shoved back to take him deeper. He set a rough pace immediately, hands locked on her hips, cock driving into her dripping pussy from behind. The couch creaked. Her ass bounced with every thrust. The sound of it was obscene in the quiet house, wet and sharp.

"Stepbrother," she gasped, fingers clawing the cushion. "Harder. Stepbrother, harder."

He gave it to her. He fucked her like the weeks of teasing had been a debt, hips snapping, balls slapping her clit, one hand sliding up her spine to pin her shoulders down. She took every inch and begged for more, voice going ragged, pussy clenching around him so tight he had to grit his teeth.

"You feel that?" he growled. "That's your stepbrother's cock splitting you open. You asked for this."

"I did. I want it. Don't stop. Don't you dare stop."

He didn't. He pounded her until her legs shook and her moans turned into a string of yes and please and his name mixed with stepbrother like she couldn't tell them apart. Then he pulled out, flipped her onto her back on the cushions, and shoved her legs wide. She looked ruined already, hair wild, mouth open, cunt shiny and gaping for him. He pinned her thighs apart and sank back in, missionary, deep enough that she arched off the couch.

His hand found her throat. Light. A question more than a grip. She covered his wrist with her own hand and pressed him closer, eyes locked on his.

"Yes," she whispered. "Like that. Choke me a little. I want to feel it while you rail me."

He tightened just enough to make her breath catch, never enough to scare her, and fucked her hard. She begged through it, voice thinner under his palm, legs shaking around his waist.

"More. Please, more. Use your stepsister. I can take it. I want your cum. I want you to fill me."

He kissed her once, messy and claiming, then pulled out again because he wasn't done watching. He sat back on the couch and dragged her over him, facing away. Reverse. She understood at once, swung a leg over, and sank down onto his cock with a broken moan, hands braced on his knees.

"Ride it," he said.

She did. She bounced on him, greedy, taking him to the root every time she dropped. He watched his cock disappear into his stepsister's cunt, slick and shining, her ass spreading over his lap. He slapped it, open-palmed, and she yelped and ground down harder.

"Again."

He slapped the other cheek, then the first, pink blooming under his hand while she rode him like she was trying to keep him forever. Her pussy fluttered. She was close. He could feel it in the way she tightened, in the desperate little sounds she made every time he filled her.

"I'm gonna come," she gasped. "Hugo, stepbrother, I'm gonna—"

"Come on my cock. Then I'm filling you."

She shattered. Her whole body locked, cunt pulsing around him, a raw cry torn out of her as she came and kept riding through it, milking him. He grabbed her hips and thrust up into that clench, once, twice, and then he was gone. He buried himself deep and came hard, pulse after pulse, a massive creampie flooding his stepsister until it leaked out around his cock and ran down onto his balls. She whimpered and stayed seated, taking all of it, squeezing like she wanted every drop kept inside.

They stayed like that until the shaking eased. He softened inside her, cum slipping out when she finally lifted off, thick and white on her thighs. She turned in his lap, curled against his chest, and kissed him deeply, slow and filthy and sweet all at once. Her hand rested over his heart.

"This is just the beginning," she whispered. "Our secret. Your stepsister is going to keep begging for this cock. You don't get to pretend anymore."

He held her and didn't argue. They cleaned up fast, couch wiped down, panties back on, sweatpants tugged up, the evidence of what they'd done reduced to a flush on her cheeks and the ache between her legs. Upstairs, before she slipped into her own room, she looked back at him in the dark hall.

"Tomorrow night," she said. "I'll sneak into your room. I'll get on my knees again. And I'll beg my stepbrother to fuck me until I can't walk."

He nodded, already hard at the thought, already lost.

The lock on his door would never matter again.
