I came out of the bathroom and the first thing I saw was my stepsister and her huge, incredibly sexy butt. I told her to put some clothes on, but she refused. I couldn t hold it in any longer, so I told her she had to help me with my erection because she had aroused me and she had to take responsibility before our parents came home. To keep it a secret and make sure it never happened again, she suggested cutting off my dick. In the end, I agreed because I love her.
