contrary to (apparently) common belief, shit doesn’t just hang out at the back door. it waits in the upstairs hallway. If, for whatever reason, it happens to be riding a little low, your penis (we’ll call him Ted) punches that disgusting son of a bitch in the face until it gets back in that fucking hallway! The back door however is so tight and small, that any residue from the shitfight is suctioned and squeegeed off. And, if you still aren’t sure, throw Ted in her mouth for a bit. Saliva really seems to get him clean again. In the heat of the moment (if you are doing it right), she won’t even care.
