カズマと久我山の奇妙な廃校探検

Kazuma (straight) is a big horror freak, so when his friend Kuga (gay) invites him on a test of courage in an old school, he follows along, but when they get there, Kuga says that every time Kazuma gets scared, he gets to do "something sexy"...!?
It's not super scary and there's no game overs. Also it's only R15; there's no 18+ CGs, so don't expect that.
