The house was silent except for the low hum of the refrigerator and the occasional creak of old floorboards. Lena, twenty-three and home from college for the summer, padded barefoot into the kitchen in nothing but an oversized t-shirt that barely covered her ass. She poured a glass of water, unaware that her older brother Marcus had been watching from the shadowed hallway.
Marcus was twenty-eight, broad-shouldered, and had spent the last week fighting the same filthy urge that had been building since she moved back in. He stepped into the light, his voice low and rough. “Couldn’t sleep either?”
Lena turned, startled. “Jesus, you scared me.”
He didn’t answer. He crossed the room in three strides, took the glass from her hand, and set it down. His fingers wrapped around her wrist, firm, unyielding. “You’ve been walking around here like you don’t know what you’re doing to me.”
“Marcus, what the hell—”
He pushed her back against the counter, his body pinning hers. One hand slid under her shirt, gripping her bare hip hard enough to bruise. “Shut up. You’re going to listen.”
Lena’s breath hitched. She tried to shove him, but he caught both her wrists and pinned them above her head with one hand. His free hand yanked the shirt up, exposing her breasts. He squeezed one roughly, thumb dragging over the nipple until it stiffened.
“You’re wet already,” he said, voice dark with certainty. He shoved his knee between her thighs and felt the heat through her thin panties. “Don’t lie to me.”
“Stop,” she whispered, but it came out shaky, not convincing.
Marcus laughed once, low. “No.” He released her wrists only to spin her around and bend her over the counter. The tile was cold against her cheek. He ripped her panties down and kicked her feet apart. Two thick fingers shoved inside her without warning. She was soaked. He worked them deep, curling, fucking her with them until she made a broken sound.
“That’s it,” he growled. “Take it. You’ve been asking for this since you got home.”
He freed his cock, thick and already leaking, and rubbed the head against her slick folds. Lena squirmed, but he gripped her hips and drove in with one hard thrust. She cried out, the stretch burning. Marcus didn’t pause. He fucked her in deep, punishing strokes, the sound of skin slapping skin loud in the quiet kitchen.
“Fuck, you’re tight,” he snarled, one hand fisting her hair, yanking her head back. “This pussy was made for your brother’s cock, wasn’t it?”
Lena’s fingers scrabbled at the counter. Every thrust forced a wet sound from her. She hated how her body responded, clenching around him, heat flooding low in her belly. Marcus reached around and rubbed her clit in tight circles, rough and relentless.
“Come on it,” he ordered. “Come while I’m buried in you.”
She shattered with a choked moan, thighs shaking, pussy pulsing hard around his cock. Marcus didn’t stop. He fucked her through it, harder, chasing his own release. When he came he stayed deep, grinding, filling her until it leaked down her thighs.
He pulled out slowly, turned her around, and lifted her onto the counter. His mouth crashed over hers, tongue pushing in, claiming. “We’re not done,” he said against her lips. “Upstairs. Now.”
He carried her to his bedroom, dropped her on the bed, and stripped the shirt off her completely. For the next hour he took her again and again—on her back with her legs over his shoulders, on her knees while he held her wrists behind her, riding his cock while he slapped her ass and told her exactly what a filthy little sister she was. Each time she came it was harder, her voice hoarse from begging and denying in the same breath.
By the time he finally let her rest, dawn was bleeding through the blinds. Marcus pulled her against his chest, one hand possessively between her legs, fingers idly stroking the mess he’d left inside her.
“You’re staying in my bed the rest of the summer,” he said quietly, dark satisfaction in every word. “And every night I’m going to remind you who this cunt belongs to.”
Lena didn’t answer. She only pressed closer, already aching for the next time he would force the pleasure out of her. Outside, the house stayed silent, keeping their secret.
