I often visit a friend of mine who has a son, aged 19. My relationship with the young man had been very normal until I caught him watching me through the key hole of the bathroon while I was showering. That was about a month ago. last week, I was taking a shower when he came in saying that he forgot something there. He stood there staring at my cock. I felt embarrassed and quickly covered my package. He smiled and went away. What would you do if you were in my place?
