U.S. Patent No. 7,122,000
We all have heard of snorting coke off of a stripper's tits, but taking a bong hit out of her vagina?
This "water pipe providing sexual stimulation" seems to be just too depraved to be true. In instances such as this, I find it best to let the patent do the talking:
"The lower end cooperates with the wall of the vagina to form a water reservoir holding water in the lower end and the vagina. A stem is received into the inlet port with an end opening submerged in the water reservoir. Suction applied at the exit port draws air through the stem to bubble through the water reservoir to generate stimulatory vibrations transmitted to the vagina. Optionally, a bowl holding combustible material communicates with the stem such that smoke bubbles through the water reservoir to simultaneously filter and cool the smoke and generate stimulatory vibrations."
Appropriately enough, this ingenious device was invented in Las Vegas.
