This CG sets, is a afterdays-like story from クラスの女子を水責め+えっちしてみた(Class no Joshi o Mizuzeme + Ecchi Shite Mita)
You can see it in here: http://g.e-hentai/g/816980/e68c163e3c/

Well, I would love to see 水中マゾカノ(Suichuu MasoKano) than this, to be honest. But unfortunately, the chapter 5 still not any plan.
And this only is the First Class? So it will have the Second, the Third, and the Forth, and so on?
God, maybe I need some donate in future.....
