I cheated with my BF's best friend
I found out my BF made out with another girl when he was on spring break with swim team.
I'm in a class with his friend so when we were doing a partner project at his apartment, I flirted and we ended up having sex.
I went to my BFs apartment and had sex, and I even made him go down on me.
He has no idea, and I haven't broken up with him cuz I haven't decided if I want to LOL.
