My stepsister came in my room and tried to say I’m being creepy. Yeah, I’ve peeked in on her in the shower, and stare at her tits through her shirt. But she doesn’t wear a bra and I can tell that she wants me to look. Such a little slut! She told me that I had to quit being perverted and I told her that I have something over on her. I said I was going to tell her step-mom and my step-dad if she didn’t jerk me off. I mean come on, I found a sex video of her on her computer. I’ve came so hard to it like 20 times. Now, I’m going to cum so hard on her. She was disgusted to have my cock in her hand .I loved it! The more she seemed to not like it the harder I got. She said I was taking too long, so she showed me her panties and continued to jerk me off.
