The target is students who have just had their first period... A pedophile teacher gives sexual training to students with underdeveloped bodies in the school library in the name of sex education... After losing their virginity, he teaches them how to cum with his big dick, and continues to torture the girls even though there are other students around. The girls try to suppress their voices and plead, "Teacher... it hurts..." in a voice that no one can hear, but they end up being creampied...
