When a man knows that he is going to die very soon (killed by a bunch of zombies ^^), it’s pretty logical that he wants to leave something behind. In this case Busujima is the chosen one that should be giving birth to children of these man.
Ayano is the kind of girl that gets upset pretty quick and since she has gigantic tits you should avoid calling her “Milk Cow” and suchlike. Yet after hitting you she lets you do very pervert stuff with her and I guess playing with Ayano’s sexy pussy is enough compensation for the pain.
Azuma doesn’t recognize his extreme attractive teacher Ms. Kyujou at first, but while going for a night out he realizes that the woman next to him is her. So he makes his move, but will she reciprocate his feelings and allow him to have forbidden teacher student sex?
