A classmate, a pervert, accidentally got an erection while on a crowded train, leading to an intimate encounter! His classmate noticed and showed disgust, but I couldn't resist and let his penis rub against my genitals before penetrating! AP-123

I only ever saw a female classmate in class, and by chance, we ended up on the same crowded tram. In the cramped, close proximity, I unconsciously got an erection. She looked disgusted, but unable to move, and with her unable to resist, I couldn't stand it anymore and secretly rubbed my penis against her body, committing a perverted act! That's how I violated her!
