You have to love Japan's ability to be perfectly blatant about their obsession with all things kinky (but stammer in public over the slightest little embarrassing thing). It's all so ... in the closet. Yet you can buy spanking games for the DS (not to mention sweat-mopping and witch-touching).
The latest in this deliciously passive/aggressive series of DS titles is KimokawaE, a game which allows you to spank one of the characters and displays a nice shot of her butt and other, uh, prominently displayed goods for your smacking pleasure. She also pees on things and takes baths. Don't ask me why I would expect anything less random from Japan.
The game comes out Christmas day in Japan. Surprise, I got you a spanking simulator!
