“What if I show off my erect penis to just the high school girls on the train to school and rub my crotch to crotch?”

High school girls are at an impressionable age, and that doesn't mean they aren't interested in men's bodies. However, it should not be led by a man, like in a molester or a pick-up. I show them my cock at their own pace, and when I feel aroused, I slowly rub my crotch against them. A high school girl whose body is dominated by excitement accepts a stranger against her own will.
