A pure-faced and childlike schoolgirl with black hair in a school uniform awakens to her sexuality... A perverted homeroom teacher and his student's forbidden insemination extracurricular lesson!! Open the window and it's the Kanda River, in a rundown apartment's four-and-a-half tatami mat room, my student learns pleasure... and love. 'You're not a kid anymore. This obscene lower half is...' I never imagined it would be with my student... A pure black-haired long-haired girl growing so erotic in just one day.
