DQN is immersed in aphrodisiac and falls into sex, and her beloved girlfriend gets a scumbag

Is DQN better than me? Damn it! I encountered a group of DQNs from my former classmates who bullied me when I was a student...I was taken to my alma mater, which had been abandoned and restrained, and Yura (the lover) was gang-raped in front of me. I get a scumbag erection when I see Yura, who is not aware of me, taking another man's cock and feeling it in a silly way...I can't forget my excitement and try having sex for the first time, but the reaction is completely different. When Yura's behavior stutters and follows her... she has an aphrodisiac sex with her DQNs! ? I clenched my crotch as I cried.
