When a mustachioed man goes down on a girl. Like dipping a paint brush into a can of paint, he fills the bristles of his mustache with her lady juice. He then uses his pussy-juice soaked mustache to coat her body with her own girl cum, like a nurse cleaning a patient with a wet sponge.
Me: "Last night Sarah was feeling extra dirty so she asked me to give her a mustache spongebath."
Sarah's Mom: "What?"
Me: "Just cleaned her up a bit."
Sarah's mom: "Oh, that's nice."
Me: "You have no idea."
