Ever since she accidentally felt good during a horizontal bar class in physical education, she has been obsessed with straddling the horizontal bar and rubbing her crotch in the park after school. Girls who can't stop this [secret pleasurable play] are looking for even more pleasure and are slightly expecting an adult man to call out to them!

I never thought I could do something that felt so good in physical education class (horizontal bar)! By rubbing your crotch against the horizontal bar, a pleasure you've never experienced runs up your spine! A girl who became addicted to acme takes a detour to the park after school and secretly masturbates with a horizontal bar. I will teach naive kids who don't know the pleasure beyond that how to feel even more comfortable!
