ROE-245 | Swimming lessons crowded with middle-aged men. Beautiful big-breasted instructor Yuka Mizuno gets gang-raped and impregnated.

A few years after I started working at a swimming school, the only way I could release my sexual frustration was to take off my swimsuit and swim naked in the empty pool early in the morning. After years of not having sex, I was no longer able to suppress the desires that were building up day by day. However, I was found out by the owner of the swimming school. Due to the recent poor business performance, I was ordered to hold a photo shoot for perverted old men wearing an obscene competitive swimsuit with a sharp crotch area and a wide open chest.
