I (24m) was sitting in my room, staring at the ceiling, lost in my thoughts. My sister was a thirteen-year-old girl, beautiful as a rose in the garden. She had long dark hair, big eyes, and a sweet smile that could melt any man’s heart. I was twenty-four years old, tall, and muscular. I knew I was too old for her age, but I couldn’t help it. I wanted her so badly.

One day, after school, I thought of how to make her mine. I decided to invite her to watch a movie with me. She agreed because she loved movies. When she arrived, I locked the door and asked her to sit beside me on the couch. She was startled but didn’t resist. I started the movie, but my focus was on her. I touched her knee, then her leg, and then her hand. She pulled her hand away, but I didn’t stop. I leaned closer and whispered in her ear, “Let’s make love, Sis.”

She looked at me, shocked, but didn’t say no. I touched her breasts, and she turned away, but I didn’t stop. I unbuttoned my pants, and she tried to move away, but I grabbed her wrist and pulled her towards me. She was petrified, but she didn’t scream. I took her hand and put it on my erect penis. She looked at it, then at me, then down again. She seemed scared but didn’t resist. I took her hand and guided it down to my penis, and she touched it gently. I was getting hard. I pushed her down onto the couch and mounted her.

She was tough, but I was stronger. I forced myself into her. She whimpered, but I didn’t care. I slammed into her hard, and she cried out. I kissed her neck, biting her, and she winced. I grabbed her breasts and played with them, and she moaned. I felt her warm and wet around me, and I came inside her.

I pulled out of her, and she sat up, crying. I sat beside her on the couch, looking at her. She looked at me, then away, then back at me. I smirked, and she knew I was enjoying her pain. I kissed her and she kissed back, and I felt her hand on my chest. We made love a few more times, and she came to like it. After that, we kept our secret.

I invited my sister for a weekend. She was excited, but I had other plans. I took her to the basement where I had a dungeon set up. I had chain, whips, handcuffs, fucking machine, and other BDSM stuff. She was scared, but I assured her it would be fun. I tied her up and gagged her, and I started the fucking machine. She started to moan. She looked like she likes it. I took a whip and started to whip her. She screamed, but it was muffled because of the gag. I saw her skin tear and bleed, and I felt aroused. I took a knife and started to cut her with it, and she screamed louder. I fucked her harder and faster. I pulled out and grabbed her breast, squeezing hard and making her nipples bleed. I slapped her face, and she felt dizzy. I took a needle and injected her with heroin, and she passed out. I inserted a butt plug into her, and she woke up in pain. I fucked her asshole and her pussy at the same time. She screamed in pain and started crying. I didn’t care. I kept fucking her until I came inside her.

I untied her and let her go. She fell on the floor, sobbing. I felt no empathy or sympathy. I just wanted to destroy her, make her mine completely. I went upstairs, leaving her sobbing in the basement.

The next day, I invited her again. She knew what I wanted, but she wanted the drugs. She was hooked now. I took her to the dungeon again, and we did it all over again. I enjoyed seeing her bleed, hearing her screams, watching her cry. I felt powerful, in control. I knew it was wrong, but it felt so right.

As the weeks passed, I became more brutal. I started to beat her with a stick, leaving wounds on her back and legs. I would hold her down and spit on her face. I’d take a hairpin and stab her arms and legs. She became numb, but I didn’t stop. I made her drink my piss, and she drank it without complaint. We had sex in the most brutal ways, and I recorded everything. I was addicted to her pain, and she was addicted to the drugs.

One day, I decided to take it to the next level. I took her to the basement and tied her up. I started to cut her with a knife, but I was careful not to kill her. I wanted her to feel pain for as long as possible. I took a saw and started to cut her arm, and she screamed in agony. I put a hot iron on her skin, and she yelled. I cut her thigh and stomach, her breasts and belly. She bled profusely, and I laughed. She looked at me pleadingly as if asking for mercy, but I had none. I cut her face, her neck, and her chest. She looked like a piece of meat. I used a chainsaw to cut her legs off. I bandaged her wounds, and she passed out.

The next day, started with little chat. I asked her how she was feeling. She didn’t respond. I took out a small knife and cut her wrist, watching the blood gush out. I cut her stomach, and she started bleeding again. I cut her throat, and she choked on her blood. I opened her chest, cut her heart out, and watched the life drain out of her eyes. She was gone, but I wasn’t. I felt powerful, invincible. I took her heart and threw it in the fireplace. I felt my heart pound with excitement, and my cock twitched. I sat in my chair, watching the flames consume her heart. I got up, went to the bathroom, and took a shower. I felt clean, free.
