What you have to do in order to go bean bunging.

The act of getting your ballsack inside a vagina or butthole.
It's like when your pillow won't go in the pillow case so you gotta shove your whole arm inside the pillow case to pull the pillow in.

But obviously with your balls to get them inside the selected hole.
