Truffle mousse is when you pull your dick out of the asshole and continue fucking her pussy, then put it back in her asshole. And the light brown substance around her asshole is truffle mousse.
Gurl you been eating ripe peaches or pineapples cuz the truffle mousse is sweet tonight. Bon àppetit! C'est Manifique!
