The rain hammered against the windows of the small council flat in Manchester, but inside the bedroom it was all heat and the thick smell of sweat. Eighteen-year-old Liam shoved his nineteen-year-old sister Chloe onto the bed, her short skirt riding up to show the thin white knickers she wore under it. "You’ve been teasing me for weeks, you dirty little slag," he growled, voice low and rough. "Walking around in those tiny tops, bending over so I can see your tits. No more playing."
Chloe tried to scramble back, but Liam was bigger, stronger, and already hard as fuck. He grabbed her ankles and yanked her toward him, ripping the knickers down her smooth thighs in one hard tug. Her cunt was bare, pink, and already glistening despite the way she shook her head. "Liam, stop— we can’t, Mum’s just downstairs—"
"Shut it." He slapped her inner thigh, the sound sharp. "You’re going to take every inch of your brother’s cock tonight, and you’re going to thank me for it." He freed his thick prick, the head already leaking, and rubbed it up and down her slit, smearing her own wetness over her. Chloe whimpered, hips twitching even as she pushed at his chest.
He didn’t wait. One rough thrust and he buried half his length inside her tight teen cunt. Chloe cried out, the sound half protest, half moan. Liam pinned her wrists above her head with one hand and used the other to yank her top down, freeing her small, perky tits. He sucked a nipple hard while he fucked her in short, brutal strokes, stretching her open.
"God, you’re so fucking wet for it," he snarled against her skin. "Forced or not, your pussy’s gripping me like it wants to keep me in. British teen cunt this tight shouldn’t be wasted on anyone but family." He slammed deeper, bottoming out, balls slapping her arse. Chloe’s legs kicked once then wrapped around him despite herself, heels digging into his back.
He flipped her onto her stomach without pulling out, yanking her hips up so he could pound her from behind. The bed creaked under them. Liam spat on her arsehole and pressed a thumb against it, forcing the tip inside while his cock kept hammering her cunt. "You’re mine now. Every hole. Every night. Free use, just like you deserve."
Chloe buried her face in the pillow, but her moans grew louder, raw and filthy. "Fuck… Liam… harder— no, don’t— oh God, yes—" Her words tangled between resistance and need. He reached under her and rubbed her swollen clit in fast circles, feeling her cunt flutter and clench around him.
When she came, it was sudden and messy, juices squirting around his shaft, thighs shaking. Liam didn’t stop. He kept driving into her, using her orgasm to push deeper, whispering filthy praise.

"That’s it, come on your brother’s cock like the forced little incest slut you are. Soaked the sheets already."
He pulled out only long enough to flip her again and straddle her chest, feeding his glistening prick between her lips. "Suck it clean. Taste your own forced cunt on me." Chloe opened obediently, eyes glassy, tongue working the underside while he fucked her mouth in shallow thrusts. Spit ran down her chin onto her tits.
Liam pulled back before he finished, wanting to finish where he started. He shoved back into her dripping pussy and fucked her with everything he had, hips snapping, the wet slap of skin loud in the room. "Gonna fill you up," he grunted. "Breed this tight teen hole. Make sure you remember who owns it."
Chloe came again, smaller but longer, walls pulsing around him. Liam followed with a low, guttural groan, pumping thick ropes of cum deep inside her, grinding until every drop was buried. He stayed there, cock softening slowly, thumb still working her clit until she twitched and whimpered from oversensitivity.
Finally he eased out, watching his cum leak from her swollen cunt. He scooped some onto his fingers and pushed it back inside. "Keep it in. You’re not wasting a drop."
Chloe lay there panting, legs spread, face flushed. After a long moment she looked up at him, voice hoarse. "…Again?"
Liam’s grin was dark and satisfied. "That’s my girl." He was already getting hard again, the rain still falling outside, the flat quiet except for their breathing and the wet sound of him sliding back into her willing, forced body.
