Anime XXX Tube - Mizugi Kanojo 3

The plot begins with a young couple, the busty Mizuho-chan and the well-endowed Hiro-kun. Hiro offers to Mizuho one night that she try swimming to become in shape. He even offers to tutor her after hours at the pool where he works because she isn't very good at swimming. Mizuho's new fitness routine proves to be far more thrilling than anticipated... Meanwhile, Takuya-kun is in a precarious situation with his clumsy but lovely neighbor Sayaka-chan... Each episode includes couples engaging in various sexual exploits that involve a lot of water, wet bodies, and incredibly exposed mizugi (swimsuits).
