Shishunki no Obenkyou is a multi-volume doujinshi, and only the first part will be animated. And the first chapter of this hentai will show us the beginning of the story, about two classmates of Kasuga and her school friend Kobayashi. The girl has an irresistible curiosity and a desire to find out what men look like below, i.e. she wants to see a real penis, and is constantly tormented by these thoughts not knowing what to do. On the same day, …
I want to see, I want to know, I want to try, a girl’s curiosity is boundless!
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.
Kobayashi and Kasuga used to go back and forth between each other’s houses, but as time went on, it disappeared.
One morning, Kobayashi arrives at school just in time to be late, and runs into Kasuga there.
Kobayashi was called out, but he felt embarrassed to go to school with him, so he turned back the way he came to escape.
After school, Kobayashi will clean the gymnasium as a punishment for being late. For some reason, Kasuga was forced to join him.
When the work was over, they talked about the old days, but Kobayashi remembered that he had sex with Kasuga and became uncomfortable.
He tries to get out, but the door won’t open.
The two are trapped in the physical education warehouse.
Kobayashi took off his jacket as it was hot inside the gymnasium.
Seeing this, Kasuga also took off his jacket.
Kobayashi can’t stop pounding because Kasuga’s chest is so different from before.
Despite her feelings, Kasuga reveals that he is holding back from peeing.
When she heard this, Kobayashi thought she had to do something and looked at the plastic bottle in her hand.
