I can't help but be attracted to my bff's boyfriend so one day I invite him over to test my theory about him feeling the same way. once I determine he is into me as well, I convince him to fuck me behind his girlfriend's back. I tell him how superior I am to her and how I could fuck him way better. I see he is getting hard so I start to suck him off. I undress and let him fuck me in different positions all the while convincing him not to tell his girlfriend and to keep it our little secret
