I am in college at a large university and live in an apartment. My roomates house is about 80 miles away. His Mom got him the apartment so he did not have a long commute to school and she was the one who found the apartment and pretty much did the whole deal up for him. She paid me for the rent all the way to the end of the school year. He goes home for the weekends all the time pretty much. I got a knock at the door one Saturday afternoon and it was his mom. I looked at her and said that he told me he was going home and he was not here. I was a little concerned and thought maybe he never came home. She said he was at home and could she come in and talk to me. My second thought was what did I do to make him mad or something. We talked for about 5 minutes and the conversation was going nowhere so I asked her if anything was wrong with him. She stood up and walked over to me and said she wanted to get laid. I about hit the floor, the woman was stunning, I could not believe when I first met her that she had a son two years younger than me. So we had some wild sex and I really enjoyed it, judging by her moans and squeals she did also. So now for the problem, or not a problem, she shows up just about every weekend that he goes home. I am loving it but what if he comes to the apartment when we are getting it on. I am not concerned about his reaction but just the fact that if he has a problem with it he lives here and that would cause a lot of tension between us. I almost feel like telling him about it but not sure how he would react because we have not really partyed together and he is always either in class, studying or at home. Am I overeacting and worried about nothing? The bedrooms had locks on them from the beginning so it is not like he could just walk in on us but it would be hard to explain why is mom is coming out of my bedroom I am sure.
