Double Decker

When a man puts on a strap-on above his cock and double penetrates a woman.

Since Roddy wasn't able to make it to our planned threesome with him, me, and his girlfriend, I just got a strap-on and Double Deckered her.

Double Decker

The double decker is a combination of the upper decker and a blumpkin. The guy is on the top tank performing an upper decker while the girl faces the wall with her feet on the toilet seat giving him a blumpkin while she drops a deuce in the bottom tank

Double decker

When taking a shit, having someone sit on your lap aiming their anus between the first person's legs. Both people shit at the same time, creating a "double" effect and saving water in the process. For utmost efficiency, time the splashes similar to Olympic synchronized diving.

She sat on my lap while I was on the toilet so we could double decker that shit.
