'What Are You Two Doing?!' - Masturbating in Public Feels Better With Her Stepbrother - Sis Loves Me

I'm growing up - I need some privacy! I wanted to touch myself all the time, but my stepbrother was always around, so I discovered how wonderful the dressing rooms at the mall are. I could finally masturbate whenever I wanted, or at least that was the case until my stepbrother caught me. What was even worse was that he offered to buy me whatever I wanted if I kept rubbing my wet pussy in front of him. Ew! I couldn't do that. Then, something took over my body, and before I could stop myself, I was doing it and saying his name. I moaned so loud that the store manager caught us! I thought that would be the end of it, but when we got home, he said he would tell our mom what happened if I didn't suck his dick. I pretended I didn't want to, but honestly, I've been so horny that I wanted any excuse to get my body all over his big cock. Maybe we could even go back to that dressing room and do everything that we can't do at home.
