My stepson walked in on me being fucked hard by his step-dad’s friend. He was worried I was having an affair. His step-dad talked to him but he still seemed very concerned. I don’t think he knows I saw how hard he was in his pants once he realized what was going on. So the next day I decided to talk to him and let him know that his step-dad loves seeing other men fuck me, and I love fucking other men while his step-dad watches.
