Fucking an ass deeply enough to encounter the shit
coming down inside. The person
being fucked can push the shit down onto the cock and out so the person doing the fucking is literally fucking the shit, or one can say they are fucking the shit out of the other person as they
pull it out on their cock.
Can be a noun or a verb.
"She
took a shit while I was fucking her ass and it turned into a really hot shit-fuck." (noun)
"I want to shit-fuck her bad so she is building up a
big turd for me to fuck." (verb)
"Did you see the shit-fuck those two had? I want to go next and really shit-fuck
the brains out of him." (noun and verb)
