We were alone in the house when she found the old camcorder. My sister Emily, twenty-one and already half-drunk on cheap wine, waved the thing at me with a smirk. "Remember when we used to film stupid shit as kids?" she said. I was twenty-three, home from college for the summer, and the look in her eyes said this wasn't about kids anymore.
She popped the tape in and hit play. The screen showed our old bedroom, empty at first. Then Emily walked in wearing nothing but a towel that slipped off her tits on purpose. "Let's make a real one," she said, already pulling her shirt over her head. Her nipples were hard. She shoved the camera into my hands. "Film it. Incest sex porn story video style. Raw and nasty."
I didn't argue. My cock was already pushing against my jeans. She dropped to her knees, unzipped me, and pulled my dick out. "Fuck, it's bigger than I thought," she muttered, then wrapped her lips around the head and sucked hard. Spit ran down my shaft as she took me deeper, gagging once but not stopping. The red light on the camcorder blinked while I held it steady, watching her cheeks hollow.
She stood up, stripped the rest of the way, and bent over the bed. "Get behind me. Put it in." Her pussy was shaved and already wet. I lined up and shoved my cock straight into her in one thrust. She grunted and pushed back. "Harder. Make it look good for the video." I slammed into her, balls slapping, the camera catching every wet sound and the way her ass rippled. She reached back and spread herself wider so the lens could see my dick stretching her open.
We switched positions fast. She climbed on top, sank down on my cock, and rode me like she was auditioning for the real thing. Her tits bounced. She grabbed the camera from me, pointed it down at where we were joined, and moaned, "Look at that. Brother's cock buried in his sister's cunt." I grabbed her hips and fucked up into her, making her squeal.
Later she flipped onto her back, legs spread wide. "Cum on my face," she ordered. I pulled out, stroked twice, and shot thick ropes across her tongue and cheeks. She licked her lips, looked straight into the lens, and said, "Swallow it all like a good slut." The tape kept rolling while she sucked the last drops from my dick.
We watched the video back together that night. It was filthy, exactly what she wanted. By the second replay she was on all fours again, and I was filming round two.
