No, this isn't a client request! LOL!
I was perusing through the porn sites (as you do) and came accross (ahem) this video. Now I don't consider myself to have any real fetishes as such, but I have to admit I found this quite sexy!
So guys (and girls), do you like the idea of being rubbed off through a nice pair of silk panties while just as this spawny fecker did in this video? There's something very naughty about it
