Japanese have all kinds of restrictions and nearly the only way of letting the steam out for them is in sexual experience.
Public sex amidst the street? well, they had an urge and it's not my business.
Girls are groped at least 12 times each day on their way to school and back home.
TV shows with fucking conquests like - thrust her hard, so that she slides down the track - some champions make their girls slide for about 10 meters long in about 10 minutes...
Another show where dad should decide if this is his daughter's tits, ass and pussy... they can fuck them to make sure.. some get pregnant...
Japanese TV shows all kinds of weird things, really.
