J’ai baisé ma demi-sœur Skylar Snow et je lui ai éjaculé dessus

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 stepdad and her stepmom 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 stepmom 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.
