Through the wires, I have found out about a game called Boon Ga Boon Ga from Japan. Apparently, the player tries to shove a fist with finger extended into an ass. The game judges your force via digital grimmaces on the screen. Unbelievable? Here’s the brochure.

It appears that the English language version and/or American one is focused on “spanking.” But I think you can see that the Japanese version is no doubt about poking your game-finger into a stylized bootie.
