Three girls were only able to get into a delinquent boys' school with a deviation score of 37.
School rules require them to have short hair, and of course the uniform is shirts and pants.
As expected, they become victims of bullying by their extremely low-level classmates.

Trial 1 5/22
There was only the men's restroom so he had no choice but to go there, where a group of guys were waiting for him
"Don't you have a penis?"
"If you're going to pee, you should use this toilet."
He resists while being subjected to insults but it's no use
He is gang-raped and creampied against his will

Trial 2 5/31
While he is changing for gym class, he is groped and raped under the guise of a physical examination
"Hey, all boys change in the same place lol"
"If your tits are that flat, you're bound to have a dick even after you've taken them off"
He is forced to strip shirtless and bullied
The teacher finds out but he turns a blind eye... no one is on his side...

Trial 3 6/8
In the library, he is trained with deep throating and deep throating until everyone has ejaculated.
As they drool, one cock after another is shoved into their mouths
and they are treated like sex toys.

Trial 4 6/15
The nurse's office turns into a sex room
Without anyone to disturb them, the men devour them as they please
From this point on, their resistance gradually fades away

Trial 5 7/1
Perhaps they got bored of the nurse's office because an orgy breaks out in the classroom after school
Although they are reluctant by this time, they put up little resistance and begin to submit
and are brainwashed into becoming sex slaves

Three unlucky girls with small, chopping-board breasts have become the class's sex slaves just because they enrolled in this school.
