The double decker is a strange sex move which consist a woman taking a shit and a guy shoves his cock in her ass without protection while the shit is coming out and then he puts it in the womans vagina and them cums then the woman farts out the cum and drips it on the guys cock then he puts his dick back in her ass while there is still clumps of shit in her then he puts in in her mouth.

When you’re so horny but you also gotta take a poop, so for some odd reason you decide to poop inside the top part of the toilet then blow a load on top of it.
My girl had me so hot but so did that Taco Bell, I had no choice but to pop off the toilet lid and drop off a double decker.
