Shishunki no Obenkyou (2021)

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