The other day I saw my step sister’s boyfriend Steve leaving in a hurry. He seemed like he was putting his clothes back on but we didn’t get a chance to talk. To find out more I decided to confront my step sister since my dad and her mom have some strict rules about having people over before our college exams. I knocked at the door but she wasn’t answering, I knew she was in there though and I decided to come in. When I opened the door she was masturbating half naked in lingerie. I confronted her about Steve and I was right, they were trying to go for a quicky while our parents aren’t home but Steve got called in at work and had to leave in a hurry. I told her that her mom wasn’t gonna be happy to hear that she had some company over before the last exams and Skylar decided that her best way to get out of trouble was to fuck me so I wouldn’t be able to say anything. I was pretty surprised by that idea but then again we’ve only lived in the same house for a little less than a year and I don’t know her that well.Apparently she was still hony and didn’t get to cum so it would be win win for everybody. Andit sure was, she sucked my dick better than my girlfriend and we also had a lot fun fucking.After titty fucking her I took her in missionary so I could see her big natural tits bounce, then Igot on the bed so she could ride me with her big ass bouncing on my dick. I knew that ourparents would be home any minute now and that wouldn’t look too good if they walked in onus like that so I tuned her around to fuck her from behind. I was planning on pulling out but Igot too excited and forgot so I ended up creampieing her. She wasn’t too pleased about it butit’s not like she can say anything to her mom anyway… lol ;-)
