[Reducing Mosaic]SW-589 It's fine to wear gym shorts! When a classmate changes in the classroom, wearing gym shorts and a gym uniform to prevent panty shots, and asks 'Do boys like this?', there's no choice but to do it.

Film Introduction

The girls are wearing bloomers to prevent underwear, so they don't mind if I'm a boy and start changing in the classroom. But bloomers know the shape of the plump buttocks, and on the contrary, they are erotic and erect! The girls teased me and asked me to help them get dressed, so I couldn't stand it and ended up rubbing my bloomers and doing naughty things!
