Plug Butter

The amalgamation of feces and semen created during a vigorous plugging and plunging of the bunghole during anal sex.

She was hot AF and let me take her ass to pound town but she gave me a nasty case of plug butter. I almost gagged.

I railed her ass good but she gave me a mess of plug butter so I wiped it off on her pillow case, flipped it over and caught an Uber while she was in the shower.
