Manga Sex - Mizugi Kanojo vol

Mizuho-chan and Hiro-kun, two young lovers, are at the centre of the plot. One night, Hiro advises Mizuho to get in shape by swimming. He even goes so far as to offer to tutor her at the pool where he works after-hours since she is unable to swim. Mizuho's new fitness routine is more interesting than imagined... Takuya-kun, in the meantime, finds himself in an awkward position with Sayaka-chan, his clumsy but lovely neighbour... Water, wet bodies, and incredibly explicit mizugi are all part of the fun in each episode's sexual adventures (swimsuits).
