Vague Game Description by White Masq
The anime that spawned from this is pretty well known, but I'll go over the basic plot in a very brief way. You play as a new student to a campus that's predominantly female student body. As can be expected in an H-game, this campus isn't all that it seems, behind closed doors (and sometimes not so subtle) it seems that those holding a certain amount of power can't get enough fucking done. Our hero isn't all that he seems either. We soon discover that, in a state of heightened arousal, his member grows to fill whatever orifice it happens to be in. Of course, our over-sexed vixens on campus all want a piece of him now. This Excellent edition comes with an extra 'episode', which I assume means a whole new H-scene or two.
