I had the video saved on three different drives, just in case. My little sister, Elena, twenty-two and home from college for the summer, thought she was alone in the house that afternoon. She wasn't. I stood outside her cracked bedroom door with my phone recording while she spread her legs on the bed, fingers pumping into her shaved pussy, moaning like a whore. The wet sounds were loud enough to hear through the door. She came hard, biting her pillow, and I had every second of it.
Two days later I showed her the file on my laptop. Elena's face went white. She tried to grab the screen but I yanked it back.
"Delete it," she hissed.
"Not happening," I said, leaning back in my chair. "Unless you want Mom and Dad seeing this. Or your boyfriend. Or your whole fucking sorority."
She stood there in tiny shorts and a tank top, nipples already hard from the fear and the heat in the room. "What do you want?"
I didn't sugarcoat it. "I want to fuck you. Whenever I say. However I say. You do exactly what I tell you and the video stays hidden."
Elena slapped me. Hard. I just smiled and hit play. Her own moans filled the room again. She froze, breathing fast, cheeks burning red.
"Fine," she whispered.
"But if you tell anyone—"
"Shut up and get on your knees."
She dropped right there in the living room. I unzipped and pulled my cock out, already thick and heavy. Elena looked up at me with hate and something else—heat. She opened her mouth and I shoved in deep, grabbing her hair. She gagged but didn't pull away. I fucked her throat slow and steady, watching spit run down her chin onto her tank top.
"Look at you," I growled. "My blackmail slut. Suck it like you mean it or I send the video right now."
She worked harder, tongue swirling, eyes watering. I pulled out before I came and told her to strip. She peeled off the clothes, standing naked in front of me, full tits, smooth pussy already glistening. I bent her over the couch and spread her ass, rubbing my cockhead against her wet slit.
"Beg for it," I said.
"Fuck you."
I slapped her ass hard. "Beg or I send it."
"Please," she said through gritted teeth. "Please fuck me."
I slammed in to the hilt. Elena cried out, pussy clenching tight around me. I didn't go gentle. I pounded her, one hand in her hair, the other reaching around to rub her clit. She came fast, shaking, juices dripping down my balls. I kept going, flipping her onto her back so I could watch her tits bounce while I railed her.
"Harder," she gasped, surprising both of us. "Fuck me harder, you asshole."
I did. I flipped her again, pulled her hips up, and drove into her from behind until the couch creaked. When I was close I pulled out and shot thick ropes across her ass and lower back. She stayed bent over, panting, cum sliding down her skin.
That was the first time. It didn't stop there.
Every night after that I used her. In the shower I made her suck me while hot water ran over us, then bent her against the tiles and fucked her until she was whimpering my name. One afternoon I caught her in the kitchen and bent her over the counter, yanking her shorts down and burying my face in her pussy first, tongue fucking her until she came on my mouth. Then I stood up and shoved my cock in, fucking her quick and rough while she tried to stay quiet so our parents wouldn't hear.
The blackmail kept her obedient, but something shifted. She started coming to my room on her own. One night she climbed into my bed naked, straddled me, and sank down on my cock without a word. She rode me slow and deep, tits in my face, whispering filthy things.
"You like owning me, don't you?" she breathed. "Like having your sister's tight cunt whenever you want."
I grabbed her hips and thrust up hard. "Say it again."
"My cunt. Your sister's cunt. Use it."
I flipped her onto her back and fucked her until the headboard slammed the wall. She came screaming into my shoulder, nails digging into my back. After that the dynamic changed. The video was still there, but she wanted it now. She started sending me nudes from her dorm when she went back to school, captions like "Come blackmail me again" or "This pussy misses your cock."
When she came home for winter break I met her at the door, dragged her into the laundry room, and fucked her standing up while our parents watched TV in the next room. She bit my neck to stay quiet, legs wrapped around me, pussy squeezing every time I bottomed out.
The last night before she left again, she came to my room after midnight. No threats needed. She got on all fours on my bed and looked back at me.
"Record it this time," she said. "I want to watch myself getting fucked by my brother."
I grabbed my phone. She spread her ass for the camera, pussy visibly wet. I filmed myself sliding into her, then set the phone on the nightstand so it caught everything. I fucked her slow, then hard, then slow again, making her beg before I let her come. When I finished inside her she stayed on her knees, letting my cum drip out while the camera kept rolling.
She watched the new video with me the next morning, hand in my lap, stroking me while we replayed the best parts. No more blackmail needed. She was hooked.
Before she left she kissed me at the door, tongue deep, and whispered, "Send me the video. I want something to touch myself to until I come home again."
I did. And she sent back a video of her own, fingers buried in her pussy while she moaned my name.
The original recording never left my drive. We didn't need it anymore. We had something better—mutual, filthy, and completely ours.
