This is an image I did recently as a request for a friend. He wanted something for his new forum site he's modding for.
So the basic principle behind this is that she pops up out of the corner of the site, licks her lips with a grin at the viewer (who is most likely fapping), and then she disappears.
It was originally stationary where she wasn't animated, but I figured I'd do the extra work to make it more special. Plus I enjoy hearing from him about how it freaks people out when it moves. If I can generate that kind of reaction from someone, than I have done my job.
Well enjoy, and remember, Fiona Fox is watching you fap.
