Tan lines around her heavy thighs glisten under the couch light. Blonde hair messy from gripping it too tight. She’s been doing this since before he was born—knows every angle to make him groan loudest. Starts slow, grinding down until his cock disappears between those soft folds. Then flips him over mid-thrust, pins his wrists above his head while she takes control. No lube needed; years of practice mean she’s slicker than a fresh bar stool at last call.
