Fantasy #861 utter helplessness. I know being upside for extended periods of time can be very dwngerous but man I would love to be upside down and wrapped, losing all sense of spatial feeling, bonus for ear plugs so I can't hear anything.
Mummification in action! One of the most helpless ways of bondage there is. I love when I am mummified for many hours and when someone puts a foot on my face and all I can do is lick it.
