So there I was the other day when I came home early from school. I had heard some noise coming from basement so I went downstairs to check it out. That’s when I saw the hottest thing ever. My Step-Sister, Dani, was laying on the couch playing with herself. I thought she was sort of hot before, but once I saw her finger banging herself like a wild sex craved mad woman I couldn’t control myself. I hid behind the corner, pulled out my phone and started to film her touching herself. I got so worked up I decided to wack off right then and there. I was just about to shoot my load on the floor when all of a sudden Dani busted me. At first she sort of freaked out and called me all sorts of mean names, but once she saw my throbbing hard on she chilled out. In fact she wanted me to watch her play with herself while she watched me stroke it. I of course didn’t turn down the offer and we both masturbated in front of one another. After a few minutes my sister got so worked up she made me get closer and she started to give me a hand job. Her soft hands felt so good I thought I was going to shoot my load right away, but luckily I didn't. I waited for my sister to cum first and  then I came second. I shot my load all over her sandals then my freaky sister put them on and walked out of the basement. Even though she wouldn’t let me fuck her, it was awesome and she promised me that she would sit on my face next time she got horny. She also made me promise not to tell anyone, not even my best friend Chucky.
