The easiest kind of visitor is our friend from the southwest. He loves to be tied up and usually does it himself. He struggles all night straining at cuffs and humping the air in a Neoprene Sleepsack. It fits him perfectly with just one zipper. He is a real escape artist and has escaped from several heavy bondage sessions. Over time I think he could find a way to escape from this piece, but short of damaging it it is quite secure. This video captures his sexual frustration which is the reason most of us love bondage.
