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

Nanami, my childhood friend, has always helped me when I was bullied. He came to help me again today when I was bullied again! But this time it's the other person's fault... He is defeated and becomes a lewd figure. Now it's my turn to put all my courage into helping! Huh... I'm getting an erection. Even though my precious benefactor is being violated. I want to see more...cry more... Ah...it's the best. I can't help but see Nanami, my favorite, like this... I'm so ecstatic that I'm in the best mood right now... Benefactor NTR! A scumbag erection!
