POST-418 - I invited my 18cm hung best friend to my girlfriend's birthday party and got cucked

I invited my trusted friends to my girlfriend's birthday party, but things went south fast. My friend decided to whip out his massive 18cm member, and I saw my girlfriend's eyes light up. Compared to my small, circumcised member, I was the laughingstock of the room. I blacked out from drinking, and when I woke up, I found her having a wild time with them right in front of me. I couldn't even stop them; I just lay there, completely paralyzed and watching the whole thing.
