I've played quite a few games like this both here and on Steam, and as it stands this is the overall best one. Not just for the lewdness, but also the stupid jokes! Before this game, jokes in games were mostly a "nice try" in my eyes, like "ha ha I see what you did there" and a smile – with this one, I've spontaneously burst into laughter several times :D
Edit: And unlike most games of this type, it's actually... finished! Done! :O And all this for free! <3
