MIAD-525 Virgin Anal Punishment

A school that exists in a certain region...there was a unique punishment for female students who violated school rules...the female students who committed crimes were deprived of their rights as students and used as sex treatment tools for male students. However, it is not a sexual treatment by normal intercourse, but anal intercourse to avoid pregnancy... Female students who have been reduced to sex treatment tools were called at that school like this... 'anal duty'.
