I'm trying to remember the name of a doujin, it had a loli zombie in it. A mad scientist modified the nerves on her soles to make them super sensitive, to the point that walking pretty much gave her an orgasm. Don't remember much about the loli's appearance other than she had visible Frankenstein-style stitches all over her body.
