A teacher at a girls' school. But he's not popular at all. After school, girls come to this dull teacher's house to ask for advice on their sexual problems! What they mainly want to know is the structure of the male genitalia. But when he explains it to them, they get an unavoidable erection! When the female student sees this, she gets horny and demands sex! What's more, when he finishes outside, she gets furious and demands a creampie with a crab hold!
