VANDR-105 Innocent pussies who have just had their first period are being developed into erotic pussies by a lolicon teacher in the library under the guise of sex education, while trying to keep their voices down.

The target is students who have just had their first period... A lolicon teacher sexually trains underdeveloped students 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 other students are present. The girls try to suppress their voices, pleading "Teacher... it hurts..." in a voice that no one can hear, but they end up being creampied...
