My younger sister is a piece of shit. She's been on and off drugs as long as I can remember, steals from our parents, lies to everyone, and has a kid she'll never see. This isn't a confession about that, though. This is a confession about how I used and abused her when she needed it least.

Two years ago she decided to get clean. She had nowhere to stay because she'd burned all of her bridges. She came around and begged me to let her stay in my spare bedroom for awhile, and I turned her down flat. She explained how she was working on getting sober and to get her child back, and that she had a job and would help around the flat. I eventually bought into her shit and let her move in.

Three weeks later, I came home early from work and she was home, laying in her bed watching television. There was a funny smell in the air that she claimed happened when she burned her lunch. She looked out of it, and I was sure she had been doing drugs right there in her bed. I gave her the benefit of the doubt. Later that night, without saying a word, she went out the front door, jumped into her car, and drove off. I eventually passed out on the sofa.

She came home at midnight, and her eyes were red. When I demanded to know where she was, she said she had gone to her boyfriends house because they'd been arguing via text. She claimed her eyes were red because she'd been crying. He was still doing drugs while she was trying to get clean, and though she loved him, had broken up with him. I called her a liar. She swore it and said she'd take a drug test to prove she was clean. I told her I was telling everyone. She begged me not to, said she'd do anything. Just out of frustration, I said "what, you'll suck my dick to get what you want??" I said it because I'd heard stories that she sucked dick to get free drugs.

At first she looked hurt, but eventually she just nodded. I was taken aback. Finally, she said "if that's what it takes." I had never looked at her like that before, but suddenly I felt a strange sensation of power and domination.

I made her get on her knees and suck my dick. Then I had her strip naked. Her tits were saggy and awful, and her pussy looked like a blown out tire stuck in a mudhole, but my power trip wasn't ending there. I made her fuck out, and she cried the whole time. When I couldn't cum looking at her awful tits swish around, I had her lay across my lap, and I did something I always wanted to do: I finger her ass. Not softly. Not gently. I just rammed a finger in using her pussy juice and banged her asshole. I demanded she tell me she liked it. She did, all the while crying.

I asked her if anyone had ever fucked her ass. She nodded. I asked if it was for drugs. She nodded again. She was still crying.

I pushed her down on the couch, spread her ass open with both hands and forced my dick into her ass. She begged me to stop, but I'd just had enough. I needed to get my frustration with her out. I rammed into her like I was trying to kill her, and by the time I'd shot my hot load up her ass, she was crying and curled up into a little ball.

The next morning, she made breakfast. She greeted me with a smile and a kiss on the cheek. Strangely, my domineering attitude did something to her. Granted, she still struggles with drugs, but every time she needs a place to say, she comes to me and gets her tight little asshole fucked hard. She loves it. I don't even care about her using anymore.
