START-586 - Homeroom teacher: ``Starting today, I will assign Shinkawa to be in charge of sex treatment.If you don't accumulate enough semen to fill a beaker within a week, you will be expelled from school, so please do your best.'' Sora Shinkawa

Sora-chan's homeroom teacher has assigned her to be in charge of dealing with sex because her contribution to the class is low. He is told that if he does not accumulate enough semen to fill a beaker within a week, he will be expelled from school, so he devotes himself to collecting semen. At first, I was embarrassed to be on duty, but if I can help the boys improve their grades, I will do my best!
