Seductive stepsister invites to observe her intimate self-pleasure session

I was walking up the stairs when I noticed my stepsister coming down. She was all dressed up and looking super hot. I couldn't help but stare at her, and she noticed. She playfully asked me if I was checking her out, and then she invited me to come up and watch her do some sexy things. I was totally down for it, and I followed her to her room. As soon as we were alone, she started to undress and I got even more excited. She sat down on her bed and started to pleasure herself, and I couldn't resist watching. She was totally into it and making all kinds of sexy sounds. I could see that she was really enjoying herself, and I couldn't help but get even more aroused. She then moved on to pleasuring herself anally, which was definitely a sight to behold. I had never seen anyone so horny and into it. It was a really hot experience and I definitely want to do it again.
