Francys Belle, the busty milf stepmom, is fed up with her stepson Sam's constant whining. She decides to give him a lesson he'll never forget. She leads him to the bedroom, pushing him onto the bed. She straddles him, grinding her big ass against his crotch. Sam's cock hardens instantly, pressing against his pants. Francys smiles, knowing the effect she has on him. She then pulls out a bottle of lube, drizzling it onto Sam's cock and her asshole. She rubs the lube in, making sure both are slick. She then mounts Sam, guiding his cock to her tight asshole. She pushes down, taking his cock deep into her ass. Sam groans, grabbing Francys' hips as she starts to ride him. Francys moans, loving the feel of his big cock in her ass. She leans back, her big tits bouncing as she rides him faster. Sam reaches around, fingering her pussy, making Francys moan even louder. She then turns around, facing Sam as she rides him in reverse cowgirl. She leans forward, her big tits dangling in Sam's face as she rides him to completion.
