Yeah I have had 2, the first I met off an adult personals site... it was fun for a few months but it got too hard to keep up after she picked up a boyfriend. (we kept it going for a month or so but he got suspicious) She was 19 I was 25 at the time..the best sex was when we would find random places around her college to do it in the open. I also met another woman off the same website that actually lived a mile from me.. she was married and her husband was overseas on business.. with his consent we met every time he went away. It was a massive turn on to have her talking to her husband while I was having my way with her. The best part was her sister lived in the house and never knew a thing.
