Tommy, the curious stepson, can't help but fantasize about his busty, big-booty stepmom. He catches her sunbathing in the pool, her tits barely contained in her tiny bikini. As she gets out, he follows her inside, watching as she towels off, revealing her shaved pussy. Tommy can't take it anymore, pushing her against the counter and fucking her hard from behind. Robbin moans, loving every thrust, before turning and taking his cock in her mouth. She then hops on top, riding him cowgirl, her big tits bouncing in his face, before they both finish with a bang.
