'i'll Be Your Sex-Slave' Step-Sis Has a Secret

Story - I got caught shoplifting a sex toy, and my annoying stepbrother had to bail me out. It was not a big deal; I was just horny, but if my parents ever found that out, they would freak out. I asked my stepbrother to keep my secret, but he said he wouldn't do it for free. If I wanted him to stay quiet, I had to do anything he wanted. The first thing he asked me to do was to use the sex toy right there in his car, in front of him. I had no choice but to raise my skirt and do it. I didn't know what was making my pussy wetter, the toy or the fact that he wanted to see me have an orgasm so badly. Later, he made me dress like a maid. I thought I was just going to have to clean his room, but when he saw me with that slutty uniform, he dropped his pants and asked me to get on my knees. I knew exactly what to do. His dick was so much bigger than I thought, and I have to admit I liked sucking it. Still, when he didn't let me go on a date, I knew this was gonna go on forever if I didn't stop it, so I asked him what I could do to make him forget about our deal. The answer was simple: I had to fuck him. He loved his little stepsister's tits in his hands and how my ass bounced on his cock. He made my pussy feel so good. Turns out I never should have stolen a sex toy - all I needed was my stepbro's dick.
