Me and my bestie was pranking my step dad and she sexed him and then they had for s**. It started out as a joke but the joke was over when she started m***********. She did it several times while I was over her house. We let him hear us making/out and I know he got off. He didnt know it was her. It was a massive turn on at the time, but it felt weird when I got home on sunday and saw him.
I am going to her house this week end and she wants to do it again. I dont know if I should. It was fun but I dont know now.
Advise appreciated .
