Puberty Study Session

Kasuga is very interested in penises that she can’t concentrate in class. Her childhood friend Kobayashi teases her unknowingly and challenges her that whoever scores worse in the next test has to obey an order from the other. Kasuga immediately sees an opportunity to look at the real penis she’s been dreaming of.
