Fisting: the act or art of putting a fist in an ass or vigina

PeeHole: The male or female tip of the urethra.

#1: Peeisting: Similar to Pisting but instead of inserting into the vajayjay or anal while peeing, the fist is inserted into the tip of the male or female urethra. (Peeisting is normally used with a lot of lube and develops over time by inserting smaller objects til the area is widen enough for the fist to enter, it normally results in the area becoming enlarged)
Example: Luna peeisting Zachary creating a wide open flow allowing the fluids to run smoothly out into the open.
