I got an erection when I saw my childhood friend who helped me being fucked by a bully

Rei, my childhood friend, has always helped me when I was bullied. When I was bullied again today, he came to help me! But this time it's the other person's fault... I'm taking my place and becoming a lewd look! Now it's my turn to put all my courage into helping! Huh... I'm getting an erection. Even though my benefactor is having sex. ...I want to see more, cry more. Ah...it's the best. I can't help but see my beloved Rei like this... I want to do it too... I'll cum inside my semen... NTR benefactor! A scumbag erection!
