This game won't tell you how exactly such thing has happened but when you will find ninja Princess Kasumi (yeah, the one from"Dead or Alive" fighting videogame) in the very beginning she will be already chained up and ready to fullfill your sexual desires without any attempts of fighting back. Find active spots and use them, try to undress her or check what additional customization options this game has - there are way more activities on the screen than you mighte xpect at first from hentai parody game. But the main purpose is pretty standard - find ways to break the will of Kasumi and turn it into pure sexual pleasure of being your individual fucktoy. Get this sexual pleasure to the maximum level for the finish and unquestionable predominance over her.
What do you think can be achieved in a school rest room? Especially if you're not alone. And with the beautiful schoolgirl Yumi - who went there to pee. And you - a depraved and lustful dude used the position for himself. Binding Yumi with a rope, this lustful dude began to mock her. It's possible to make her pee. Or just put in her vagina electric nut sack. Or roughly fuck big-chested Yumi in the rest room.
