Shishunki no Obenkyou

• Female Students

In the classroom during a test, Kaede Kasuga is having a hard time concentrating on something.
She had always wondered what the penis on the boy’s crotch looked like.
She really wanted to see it and her desire to do so only grew.
Naturally, she didn’t write anything on her answer sheet and got a zero.
Kobayashi, who was sitting behind her, saw her and made fun of her.
In a fit of pique, Kasuga decides to play a game to see who gets the highest score on the next test.
She is momentarily confused by Kobayashi’s condition that the loser will do whatever is said, but agrees that if she wins, her wish will come true.
Thus begins Kasuga’s intense study to fulfill her wish to see a penis.
