When my buddy went to his weekend drill with the reserves, I visited his girlfriend with no intention of having s** but within the first fifteen minutes of being at her place we were naked and going at it. When he called her that evening I was in their bed in my underwear, anticipating having s** with her again before I went to sleep. Now I am worried that her conscience is going to make her tell my buddy. We have been good friends for a long time and I am hoping she doesn’t ruin that.
