If you still buy “real” Christmas trees you may have noticed this device. These funnels have plastic “fishnet stocking” put on them. You pull the Christmas tree through the funnel and get it wrapped in a second.

See where I’m going? Put something stretchy (plastic film, latex) onto a slightly modified funnel, use your partner instead of the Christmas tree and get your partner tightly mummified in a split second ;-)

I would perform some additional precocooning activities like: gagging, plugging, tying arms behind the back, etc (just in case ;-P )
