VANDR-105 Innocent girls have reached puberty, and their Lolicon Teacher is taking them all to the library for a little Sex-Ed.

The target is students who have reached their first menstruation... A lolicon teacher gives sexual training to students with undeveloped bodies in the school library. She teaches how to cum with a big dick after losing her virginity, and blames the girls even though there are other students. The girls stifled their voices and complained, "Teacher...it hurts..." in a voice that no one could hear, but they even got vaginal cum shot...
