This was a "friend's" gf - later wife, I introduced them. I was already fucking her at the time, but he did not realise that. I continued fucking her until some time after they got married, in fact right up until I got married. He was often away overnight and I would call round and roger her from time to time. Oh a guys night out he was telling us all about how she loved him to tickle her ass with his finger while he was plating her pussy. Little did he realise that I had been dicking her up the ass for about four years!
