The Butt Mousepad?
Oppai Mousepads- mousepads of girls that feature 3-dimensional soft gel breasts to rest one's wrists on- have become quite popular in Japan over the past few years. You may remember that Doki Doki Majo Shinpan came out with one. A Kasumi version from Dead or Alive has even been out in the US for years (I got one myself). There's also a Yoko one from Gurren Lagann coming out soon as well. More recently, shops in Japan have begun selling loli oppai mousepads, ones where their boobs are barely there (which kind of defeats the purpose of having a wrist rest).
But now, the first of a new line of oppai mousepads has come out. Introducing, the butt mousepad! Seen above, this seems to be the first of its kind. So for those otaku that have an ass fetish as opposed to a boobs one, they can now relax their wrist on a very plump, round booty. I must say, it seems like a very tempting purchase. =b
