I got a depressed erection when I saw Yumi, the student council president who saved me, being raped.

Yumi, who is the student council president at the same school as me, is a long-time childhood friend. When she found out I was bullied by a delinquent student, she protested to help me. However, they were cunning and violent and were raped in front of me. I can't do anything, so for some reason I get an erection in that situation... "Ahhh, Yumi is my too trash as a substitute..." My favorite childhood friend gets excited when she's raped right in front of her eyes, and her worst and greatest NTR erection gets me! ! !
