What I remember about is that it stars a really perverted character who discovers he can see through an objects perspective. It opens with him using, iirc, a bike wheel to look at girls panties on the way to school. The only thing that can bring him back to his body is his sisters voice. He also uses this power at one point to spy on his sister masturbating?

Can't remember the title for the life of me and I really wanted to read more of it.
