I(M21) discovered that my girlfriend (f19) was cheating on me with this guy(18) at first I didn't want to do anything and just leave her but I decided to confront him. I went to his house to have a talk, we were alone and he just got a shower so he was still in a bathrobe and I could clearly see his soft cock print, that alone made me question myself because of how big it already was (bigger than mine hard) as the conversation goes he loses his patience and just takes everything off comes up to me and says "this is why she cheated on you want to try?" Now he was standing while I was sitting so I literally had it Infront of me and was speechless. From that he said that hard it was even bigger and to jerk him off to find out and so I did, he then pushed my head on it and made me suck it.
