The Demon King of Lust, right? He just fucks off to another world because he can, and then it's a sandbox where you point him at women and they fall over. I spent way too long on the first monster girl, the one with the huge tits and the tail. You can just keep clicking her feet. Footjob tag is there for a reason, and the animation loops while you decide if you want to corrupt her more or just leave her drooling. It's not polished, the UI looks like a flash game from a forum in 2009, but the corruption meter fills and her dialogue changes from "who are you" to "use me" and that's the whole point.

There's a harem system but it's more like a checklist. You get a slave, a virgin, a cheating wife, all with different body types but the same blank expression after you mind control them. The male protagonist is just a pair of hands and a dick, which is fine. I wish the sandbox had more to do between scenes, like a reason to walk around the castle, but you just click the next girl and the next position. Titfuck, handjob, vaginal, it's all there and it's all animated enough to get the job done.

I'd give it out of five. One eggplant for the monster girl designs, one for the corruption dialogue, one for the sheer amount of big ass and big tits. Minus two because the male domination feels samey after the third girl and the cheating scene is just a text box. But you know, sometimes you don't need a plot. You need a demon king with a foot fetish and a world full of women who can't say no. This is that.
