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

Mari, my childhood friend, has come to help me when I was bullied for a long time. Even after graduating, this has remained the same and he has come to help me! But 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 Mari, my favorite, like this... I'm so ecstatic that I'm in the best mood right now... Benefactor NTR! A scumbag erection!
