Caveats: Bondage, Lolicon
After choosing from a selection of young girls with a little sister complex, you play against them in a sliding-block game where the object is to match three or more blocks of the same suit to rack up points and power and to prevent the stack of blocks from reaching the top. You can use the power you collect to make blocks encased in bubbles stack up on your opponent's side, though she can do the same to you. If you win, you make her strip naked, have sex with her, and she becomes your sex toy. This game also features a competitive online mode.
