Dildo buried to the hilt in her spread ass, cheeks quivering from the push. Desk edge digs into pale belly. Massive thighs part wider under stepsons suited grip, straps taut around fleshy hips. Office chair rolls aside unnoticed amid heavy breathing. She bends further, heels lifting off the floor with each twist — rhythm building slow then urgent, body rocking forward against the unyielding wood. Suited stepson pumps steady, her gasps turning to moans as the toy stretches her wide open. Plants sway slightly from the motion nearby.
