We spend so much time talking all day long, sometimes you just want to express exactly what you want in a single word. And that's where Kiki de Montparnasse's kinky pillow cases come in, expressing "Sleep" on the one side and "Fuck" on the other. Good thing a pillow only has two sides, otherwise you'd probably see "TV" as the third option, the considerably more practical, less romantic option.
If that doesn't make things clear enough, there's always the more direct approach. And by direct, I mean leading him right to the door with a Mange-moi instruction. It comes in other phrases, depending on your fetish.
