Uni-OppaiMousePad
Oppai Mouse pad (It means literaly "breasts mouse pad")
Is a somewhat of subgenre in the erotic pictures . The female character is posed so her breasts acomodate on a place where there is a cushion or foam in which the wrist can rest while using the mouse, so it looks like the user is resting the hand on the character's breasts.
I would love so much to have one with Uni! on it!.
EDIT: Oh! and for the people outside tempted to clasify this as "Xenosaga" fanart, don't do it. I think her design is finally diferent enough from that of Kosmos. They look alike, but they are diferent.
Next, a dakimakura design
