Mississippi Riverboat

Much like the motorboat, except you take a runny shit on the woman's chest first. You then proceed to motorboat her, and every few seconds you lift your head up and yell "Mark Twain!"

Shari wanted me to give her a Cleveland Steamer, but I gave her an extra treat when when I gave her a Mississippi Riverboat instead!

Riverbunny

An athletic, blonde girl with a love for kayaking. Usually has a major death wish with by riding high-class rapids. Often associated with a skanky 40 odd something Riverrat. Riverbunny is known for tipping on rapids and being pinned up against boulders, and needing help with their lifejacket from said Riverrat.

*Cheezy porn acting* "Oh No!! I tipped out of this kayak, and my lifejacket feels a little loose?!" *pushes up on boobs and lifejacket* Riverrat: "I will save you riverbunny!" *swims to Riverbunny, and grinds against her (sexes her up in her time of peril)*

Upside down Riverboat

This is a sexual act that is similar to the "69". The female participant is on top and holds her arms straight while servicing the gentlemen on the bottom. The male holds the females feet in his hands and rotates the ladies feet in a circular motion to resemble the propeller on 1850's riverboats.

David Wilcox's "Riverboat Fantasy" must be playing for the entire duration of the Upside down Riverboat.

This sexual position was inspired Cowboy's and Alien's which features an upside down riverboat.

So then we Upside down Riverboated all night.

Riverbottom Bed Bug

It's a homeless person that jumps from one tent to the next sleeping with anything that drops their pants.

I hope that Riverbottom Bed Bug gets that STD taken care of before it spreads as fast as her legs did.
