I was rescued by the female class monitor after encountering a perverted woman on the tram, but she saw me in heat and raped me! HUNTA-262

I encountered a perverted woman when I boarded a crowded tram. She immediately masturbated me until I was about to ejaculate, but then my serious female class monitor came to my rescue. However, when she saw my almost-ejaculating penis, she became aroused and eventually turned into a pervert herself and took advantage of me!
