Tim, the eager assistant, plays out Dolly's fantasy, fucking her hard on her desk. She's the boss, and he's her willing subordinate. He sucks her tits, bites her nipples, making them hard. She pushes him back, straddling him, her wet pussy sliding down his thick cock. She grinds on him, her pussy lips stretching around him. He grabs her ass, slamming into her, their bodies slapping together. She leans back, her hands on his thighs, taking his cock deep, her pussy milking him until he fills her mouth with his hot cum.
