Should I tell him? I cheated on my fiance before we were engaged.It was 3 years ago,I was 20 at the time.We had only been together 3 months and I stayed at his while he went to work.Then I met his neighbor.A nice guy in mid 30's.He was just friendly at first then we got talking and he said I could hang out with him and use his gym equipment in his spare room.We worked out together for weeks.And I must admit I got horny on most occasions,getting all sweaty and seeing a sweaty,ripped guy.Then it was one time i used his shower and i came out in a towel.He was just in gym shorts and he was still sweaty and i noticed his bulge.Well i couldn't help it,i went over to him and grabbed his package and he pulled the towel off and started kissing me.He then put me on a workout bench and opened my thighs and ate me right out.Then he peeled his shorts off and my eyes went wide when i saw it.I had to suck it.Then he slid it in me and gave me another sweaty workout.We were both fulfilled after 30 minutes and when he stood up,i looked down between my legs and realized i needed another shower. The few months to follow was all about working out followed by sex,until we decided to stop it.We still share a smile from time to time and he winks at me but that's all.I still think about it and get horny and even have a good old play sometimes. But after me a my boyfriend got serious i knew that i would never do that again.Now that we're engaged i just thought i should tell him.
