Or from a couple of links on 4chan's /rs/. The whole game on the other hand, is a little rarer. Although it might be somewhere on masterbloodfer or a similar site. However, the only advantage to the game is that there are voices, there's no motion.

Also worth note, it's not really a game, there's no "bad end" scenario, you basically choose which girl you want to be with or which threesomes you want to engage in, that's it.
