I slammed the door behind me, heart pounding from the party downstairs. My sister Emma was already in my room, sprawled on my bed in nothing but a tiny tank top and panties, scrolling through her phone. At twenty-five she still looked like the same girl who used to sneak into my room at night, only now her curves were full, her nipples hard against the thin fabric.
“Lock it,” she said without looking up. Her voice was low and dirty, the way it always got when she wanted it rough.
I clicked the lock and crossed the room fast. She tossed the phone aside and spread her legs, panties already damp. I yanked them down, buried my face between her thighs, and licked her cunt like I was starving. She tasted sweet and familiar, the same forbidden flavor I’d been hooked on since we first crossed the line two years ago.
“Fuck, Jake, eat that pussy,” she moaned, grabbing my hair. I sucked her clit hard, two fingers pumping inside her. She was dripping, soaking the sheets. I could hear the wet sounds every time I thrust my fingers deep.
She pulled me up, shoved my jeans down, and wrapped her hand around my cock. “Give it to me. I want every inch.” I slammed into her in one thrust. She was tight and hot, gripping me like a fist. We fucked like animals—hard, fast, no mercy. The bed slammed against the wall. Her tits bounced under the tank top until I ripped it off and sucked her nipples while I pounded her.
“Tell me it’s wrong,” she gasped.
“It’s so fucking wrong,” I growled, driving deeper. “My sister’s cunt. My sister’s tight little hole.”
She came hard, biting my shoulder to stay quiet. I flipped her onto her stomach, pulled her hips up, and fucked her from behind, watching my cock disappear into her again and again. She reached back and spread her ass cheeks for me. “Use it. Use all of me.”
I spit on her asshole and pushed a thumb in while I kept railing her pussy. She moaned into the pillow, pushing back against me. When I felt my balls tighten I pulled out, flipped her again, and shot thick ropes across her tits and stomach. She rubbed it into her skin like lotion, then licked her fingers clean.
Later, when we were catching our breath, she grabbed her phone.
“Want to make one for the collection?”
We’d been taking pics and short videos for months—nothing that showed our faces clearly, just bodies, but enough to make the risk feel real. She set the phone on the nightstand, hit record, and climbed on top of me. The red light blinked while she sank down on my cock again, riding slow and deep so the camera caught every wet slide.
“Say it for the video,” she whispered.
“I’m fucking my sister,” I said, voice rough. “I’m balls-deep in my sister’s pussy and I’m gonna fill her up.”
She rode faster, tits bouncing, the slap of skin loud in the room. I grabbed her hips and thrust up to meet her until I came again, pumping cum inside her while the phone kept rolling. She stayed on me, grinding, letting the camera see my cum leak out around my cock.
When she finally stopped the recording she smiled, flushed and satisfied. “That one’s going in the folder with the rest.”
We lay there tangled, sweaty, the smell of sex thick in the air. Downstairs the party music thumped on, nobody knowing that upstairs their perfect family was still breaking every rule we could think of. Emma kissed my chest, already half-hard against her thigh again.
“Round three before they notice we’re gone?” she asked.
I answered by rolling her under me and pushing back inside. The phone stayed on the nightstand, ready for the next clip. We didn’t stop until the sun came up.
