The mischievous health and physical education teacher finds out that she is a boy and gives her a naughty punishment.

She is also trained in the classroom by an old janitor who has become a guru. The anus is violently inseminated and becomes a sex toilet. Even a lesson on enema torture for a pervert who loves SM! She is tied up and taught masochism!
