Bavarian Hang Glider

The act of feeding your partner an assortment of items from Taco Bell before sexy time, inserting a butt plug in their ass, gluing a small paper parachute on it, and putting them in a face down ass up position. Once there, abruptly squeeze their stomach so that the butt plug shoots out of their ass and glides down slowly. Bonus points if it lands back in their ass.
