My step sister, Jackie Hoff, walked into my room without knocking. I had my cock out so I could stroke it until I came while I thought nobody was home. Jackie skipped school so she could go out with a couple friends. I told her I was going to tell our parents because her grades were already bad. She told me she could give me a hand if I didn’t say anything. I agreed and oh my god her hand felt so good around my cock. She wrapped her big tits around it too. Soon, her friend ended up calling and she left the room. Leaving me with my cum filled balls.
