Had sex with a guy with a girlfriend

I had a really good time😛 Im his side now but I dont really mind because I have other guys that i mess around with. Lol hes my side too but i found out from a couple of my friends that he has a girlfriend. No one is really pushing me to do anything about it cause hes a HOTTY and he is known for not being loyal. So i wanted to know other peoples opinions because he wants round 2.
