Authored by the mind behind Minami-ke, Kyou no Go no Ni is a four episode OVA about a couple of fifth graders, mainly Ryota, a boy who is haplessly caught in one bad situation after another. Or should I say, one good situation after another. :3

dude, you don’t seriously get turned on by this flat-chested children erotica do you? :S
Clearly not. Nothing in this post could have possibly indicated such a thing. You’re crazy to think so.
Some of us are turned on my flat-chested girls.

Everyone has their own tastes, as long as no one’s getting hurt, let us lolicons get off on this flat chested youngins and let the craaaazy necrophilias get off on their corpses.
