Aunt's substantial backside, a beacon of temptation, draws her nephew's gaze as she bends over to pick up laundry. He can't resist the allure of her round, pillowy cheeks, and his cock stiffens in his pants. She notices, turning to face him with a smirk, knowing full well the effect she has on him. "Like what you see, huh?" she taunts, giving her ass a playful slap. He steps closer, his hands reaching for her curves, kneading and squeezing her flesh. She pushes back against him, feeling his hardness, and grinds against him. He unzips his pants, pulling out his throbbing cock, and rubs it against her ass before plunging into her tight, waiting pussy. He grips her hips, fucking her hard and deep, her massive ass jiggling with each thrust, as they both moan and pant in pleasure.
