Despite the title, there are no water sports in this doujinshi. Just one girl has her toilet malfunction and doesn’t manage to reach her neighbor's in time. That neighbor (the protagonist), then invites her to get in and have a shower. Turns out, he got more than he bargained for, as heroine is a horny virgin who loses control once she’s left alone in a boy’s bathroom...
It's now clear that Ryou will not be able to avoid falling into the same pit of depravity that Takumi did... so Takumi wants him to at least be with someone they trust! Takumi's futa wife Anri Sogahara is just the woman to fuck them both silly and teach them all about a female's pleasure.
