"Shh, not a word to your husband," Michelle whispers, pulling her brother into the closet. She hikes up her dress, revealing her plump ass and glistening pussy. Her brother's eyes widen as she spreads her cheeks, his cock straining against his jeans. Michelle leans over, her tongue flicking out to lick her brother's shaft through the fabric. He groans, his hands reaching for her ass. She turns, pushing her tits together, inviting him to fuck her mouth. He does, his cock sliding between her lips, her tongue working overtime. They fuck hard, Michelle's ass slapping against her brother's hips, her moans muffled by his cock, until they both collapse, spent and satisfied.
