Criss-Cross Chocolate Sauce

When a guy and a girl simultaneously take a dump together while having the sex. The guy sits like normal and the girl straddles him facing the other way. They then begin coitus while also shitting. The girl tries to shit between the man's legs but isn't always successful. This is usually preceded by a blumpkin.

Susan and I had both just eaten a spicy meal which caused us to have to shit, but we were feeling frisky, so we decided to perform the criss-cross chocolate sauce.
