My stepSister thought she was home alone and was working out wearing just a thong. I decided to spy on her and jerk off a little bit. When she caught me, she invited me into the room with her and said I could fuck her as long as she was able to keep exercising. She gave me head for a little bit before we started having sex as she continued her workout. The video ends with her jerking me off into her open mouth and onto her face. Enjoy!
