I have fantasized about having an invisible demon as a s** partner since I was a young teenager (I’m 47 now). The demon would fill me completely in every hole, stretching me to just the edge of ripping me apart. In ways, it’s like those H***** alien/tentacle videos except I can’t see what’s going to happen: only feel it when it happens. This is my #1 fantasy, followed SO closely by my r*** fantasy.
