this is when you fuck your girl on her period, then do anal. her shit will be the consistency of peanut butter, and the period blood will act as the jelly. you then proceed to put your dick in between her breasts being the bread, and continue to fuck them until satisfied. you can then eat the sandwich you made, but its really your preference.
