What is Mississippi Fish Tank?
1.
When you take a piss in a girl's mouth and while she gargles you jerk off in her mouth.
Dude: Hey baby, I heard about this new thing called the "mississippi fish tank", wanna try it?
Babe: Sounds weird? What is it?
Dude: You trust me?
Babe: Mmmm...yeah?
Dude: Open wide then, close your eyes, and try not too swallow.
