In this family fantasy, Penelope Kay, the naive stepsister, innocently asks Austin Pierce about anal play. Eager to educate her, Austin positions her on her hands and knees, lubing up her virgin asshole. He slowly pushes his thick cock inside, making her gasp and moan. "It's so big, Austin," she whimpers, as he fucks her asshole, stretching it wider with each thrust. He pulls her hair, slapping her ass as he pounds into her, making her scream in pleasure. Penelope takes it like a good little slut, her asshole gaping as Austin pulls out, leaving her well-fucked and satisfied.
