An advanced sexual act typically described as a "No handed spider monkey" The Jedi Master usually involves deep penetration while balancing in a position where one, or all individuals involved are in danger of slipping, falling over, or off of the surface which they are positioned upon. (edge of a couch, bed, etc.)
There wasn't anything on the bed to hang on to. So, I brought out the jedi master!
