Is it normal that im sleeping with my sisters ex fiance
I've known him for about 7 years he was my older brothers best friend, I was only young at the time then my 18 year old sister started dating my brothers mate. Let's call him Jimmy. I always had a small crush on Jimmy, but never said anything. And ofcourse after a year things turned around, they broke up, she moved out. It was a pretty serious relationship, he moved on with someone else. 4 years later we recently started talking via Facebook and meet up one night, and we've been meeting up and sleeping together on a regular basis. it seems so forbidden and that just makes it more kinky. We know we shouldn't be doing it but we also know the sexual tension has been there for years.
Is this normal or should we stop before someone gets hurt?
