Wood-paneled staircase. Dim lamps glow on black lingerie clinging to her pale skin. Stepson's hands roam her ass, peeling straps aside. Blonde stepmom arches back, pussy swallowing his cock missionary-style on the steps. She flips him onto the Persian rug. Stockings taut. Legs locked around his waist. Tits bounce wild in the vintage room. Heels dig into his thighs. Stair rail shakes. Stepson pounds up relentlessly. Her gasps fill the ornate hall.
