The Waterfall Of shame 

A depraved sex act that involves slowly pouring warm water over a female’s clit until she pees, then scolding her for being filthy. Enjoyed by men who like to yell and women that like to be yelled at.

The Waterfall Of Shame

Woman: Please stop I can’t hold it anymore
Man: You filthy little child!

The Waterfall

When a woman squats over the mans face before squirting and lets her holy refreshing water run into his mouth. Have you tasted the spring of life yet?

I want you to wake me up with the waterfall from your panties!

Making out for a prolonged period of time.

The Waterfall

A woman holds open her ass, and her partner pisses inside. After they're done, the woman stands over the partner and pisses in their mouth from her ass. Thus creating a waterfall.

"Yo man, me and muh girl just did the waterfall!"
"How did it taste?"
"Pretty spicy"
