START-586V Homeroom teacher: Starting today, Shinkawa is appointed as the duty student. If you do not manage to collect enough semen to fill a beaker within one week, you will be expelled, so do your best. Sora Shinkawa

This work features adult performers dressed in school uniforms as cosplay. Sora-chan (23) is assigned by her homeroom teacher to a special duty because her contribution to the class is considered low. She is told that if she does not fill a beaker with semen within one week, she will be expelled, so she earnestly works to collect it. At first, the duty was embarrassing, but if this helps improve the boys’ grades, I’ll do my best! All performers in this work are adults aged 19 and over.
