She was already wet when she climbed into my bed that night. Her body slid under the covers like she owned the place, because she did. My sister. Twenty-eight, thick thighs, heavy tits that bounced when she moved, and a cunt that had been trained on my cock for the last three years. No more sneaking around like we used to. Tonight she wanted it raw and deep.
“Fuck me hard, big brother,” she whispered, rolling onto her back and spreading her legs. “I want you to wreck my cervix again.”
I didn’t waste time with foreplay. She was dripping already, slick and hot. I shoved two fingers inside her first, feeling how tight her walls gripped me, then pulled them out and lined my thick cock up with her entrance. One hard thrust and I buried half my length. She gasped, back arching.
“More,” she begged. “All the way. Hit that cervix.”
I slammed the rest of the way in. My cockhead punched straight into the firm ring of her cervix, stretching it open just enough to make her cry out.

She loved that feeling, the deep, bruising pressure that made her whole belly ache. I stayed there, grinding the head against it, feeling her cervix kiss and flutter around the tip like it was trying to suck me deeper into her womb.
“Shit, yes,” she moaned. “Pound it. Don’t be gentle.”
I pulled back and drove in again, harder. Each thrust bottomed out with a wet slap, my balls smacking her ass while my cock battered her cervix. She clawed at my back, legs locked around my waist, pulling me deeper every time. Her pussy made filthy squelching sounds around my shaft, juice running down to soak the sheets.
I flipped her onto her stomach, yanked her hips up, and mounted her from behind. Doggy always let me go the deepest. I gripped her hips and started fucking like I hated her, long, savage strokes that drove my cock straight into the back of her cunt. Every time the head rammed her cervix she let out a broken whimper that turned into a moan.
“Right there,” she panted. “Keep hitting it. I want to feel it tomorrow.”
I reached under her and rubbed her swollen clit while I pounded. Her cervix was getting battered now, puffy and sensitive, each thrust making her whole body jerk. She came hard, cunt clenching and pulsing around my cock, but I didn’t stop. I kept driving through her orgasm, using the extra slickness to fuck even deeper.
When I flipped her again onto her back and folded her legs to her chest, she knew what was coming. Mating press. The position that let me really wreck her. I sank in balls-deep, my cockhead pushing past the tight ring of her cervix and lodging right inside the entrance to her womb. She screamed, eyes rolling back.
“Oh fuck, you’re in my womb,” she sobbed. “Don’t stop. Breed me.”
I fucked her like that for what felt like hours. Short, brutal thrusts that kept my cockhead inside her cervix, stretching and battering it. Her belly bulged slightly with each thrust. Sweat poured off both of us. The room smelled like sex and sweat and her dripping cunt. Every time she came her cervix squeezed my cockhead like a fist, trying to milk me.
Finally I couldn’t hold it. I buried myself as deep as I could go, cockhead locked inside her cervix, and unloaded. Thick ropes of cum pumped straight into her womb, flooding her. She came again just from the feeling of being filled so deep, her body shaking under me.
I stayed inside her until I softened, then pulled out slowly. A thick stream of cum leaked from her stretched hole, but plenty stayed trapped behind her battered cervix. She lay there panting, legs still spread, smiling like she’d just won something.
“Next time,” she whispered, “I want you to fuck my cervix until I can’t walk.”
I already knew I would.
