性交研究週間
Description:
The week of mandatory intercourse study begins.
Yuki, the class president, is pressured to have intercourse as soon as she arrives at school, but she can't refuse...
During the first period of PE, she has full-fledged sexual intercourse with all her classmates.
Yuki writhes in agony from unexpected trouble.
Yuki and her friends go to the men's restroom to get rid of their seemingly never-ending sexual desires.
The three of them stick their asses out and continue to have sex incessantly...
During lunch break, Yuki is put in a dirty machine and can't rest...
Yuki's pussy is ejaculated one after another as they do as they are made to do.
In the sixth period, they have a joint class at the swimming pool.
The two exhausted pussies are penetrated by the male genitalia without mercy!
After school, Yuki and Satsuki think they can go home, but something unexpected happens to them.
They have no choice but to open their crotches to strangers.
