One participant is sitting on the upper deck of a Toto Toilet while your partner is sitting on the lower deck; with the seat warmer on and the water blasting against their genitals. The upper decker is receiving Fellatio while both parties are passing a Cleveland steamer.
Guy 1: Gawd! Julia is such a basic bitch, i cannot stand her.

Guy 2: Sure, but at least her parents are rich enough to afford a Toto Toilet.

Guy 1: So?

Guy 2: She totally gave me a Steamy Upper Decker, Double wet Blumpkin
Guy 1: Legendary!
