have you ever walked in on someone having sex? What was their reaction and yours? Was it a turn or or turn off? I have only had this happen during college when I stayed at the dorms and then later on when I shared an apt with a roommate. The first time I came back to our dorm early only to be greeted by the sight of my roommate ass pumping down. I immediatety turned around and walked out. When I shared an apt later on I walked by my roommate room hearing someone noises I walked over to see some girl he had just met riding him for all he was worth. They did not see me and I watched for about a min. She had really nice boobs seeing that got me worked up so I went back to my room and rubbed one out.
