sister fister

a brother or even a sister that likes to casualy fist their sister up the vagina or even the arse hole. Most of the time resulting in a very sore vagina/anus, and if caught resulting in a sentence of 10 years in jouvey.

(here is a role-play of a sister fister and his sister)
Kirsten after a long sleep
Kirsten: o hi there Aaron i didnt see you over there in that dark corner.
Aaron: You dont need to see me, you just need to feel me
Aaron and Kirsten both grin and Kirsten turns around

fistathon

A fistathon is my favourite pastime. When a man and two or more women have a group fisting session, the man usually fisting both there vaginas at once, or a man fisting a woman while she fists another woman. Let me get this straight, the man is the fister, not the fisted. It is done gently and creates a special energy also known as fist nirvana, which fisters find quiet surreal and epic. fist on!

Lets go to pumpkin tits house for a four-way fistathon!
By the fistfull!
It will be fruitfull!
which nobody can deny!

Double Fisted Helicopter

An advanced technique for performing oral pleasures on a man.

1. Hold the penis with both hands
2. Insert penis in mouth
3. While moving head up and down rotate hands and arms in opposite directions.

Thus, making a helicopter blade motion with double fists.

Woman: "I'm feeling really creative and experimental tonight. What would you like me to do?"

Penis: "I heard about this thing called a Double Fisted Helicopter"

Woman: "Oh yeah! I learned that from my mom. It will feel great"
