[MF] I hooked up with my brother’s bully

My brother (21m) and I (19f) go to the same college. He’s had a lot of problems with his roommate in the dorm bullying him. I don’t know all the specifics of what’s happened but I know it really bothered him.

A couple weeks ago I went to his room to give him something. He was gone but his roommate was there. We hadn’t met before. We started talking things got flirty and long story short he ended up fucking me.

The sex was really good but honestly I feel kind of bad about the whole thing given the situation with my brother. The guy was even making fun of him when we were talking. But he was extremely hot and I was horny and it just kinda happened.
