I have a step sister that has a son that is 24. I am 27. We have grown up like brothers and it has been really odd cause whenever we talk and hangout the conversation always goes to cocks and size...j/o stories...sex stories...and the other day I was in my room ... we are roommates...and I was j/o. I had not realized that I left the door ajar and got that feeling that someone was watching...when i looked up it was him...he walked in my room like he didnt know what i was doing and then played it off like he just caught me..."oh man dude..next time lock your door." I know that he was watching for a little while. I have also noticed that sometimes he will say he is leaving for work and then 20 min later comes busting in my room saying he "forgot" something. I know he is not gay or anything but I think he wants to see my cock. Actaully I am curious about his too. What do I do? say you show me yours and i will show mine?
