## Description
Because of a certain experience, the protagonist has an abnormal attachment to swimsuits.
He ends up raping a girl in a swimsuit! He is arrested, but gets released the same day.
The reason behind that is a dark syndicate who need his powers...

The man becomes a dark sexual trainer, and to fulfill his mission as well as satisfy his lust he rapes, tortures and ejaculates over the girls from a reputable swimming club.
He repaints their blue swimsuits white, and they moan feebly as they lie covered in his semen!
Women who don't wear school swimsuits are worthless!

Will the girls be buried beneath the cocks of the men abusing them? Or will they drown in a pool of semen before that happens? The choice is yours.
