Submission Gymnasium Storeroom ~ Definitely want to win against the cheeky and busty subordinate high school girl ~ [RJ01230764] [Vitamin CCC]

I am the founder and leader of this school’s “Game Club.”

There is only one other member, Airi Himesaki, a cute girl.
(Since there are only two members, it is actually a “game association”)

Himesaki is better at games than me.

I have never won Himesaki.
I vent my frustration by masturbating Himesaki.

However, one day, Himesaki knows that I am masturbating, and she is thoroughly teased.
