Kitty Valance, a tattooed vixen, seduces her sisters in a steamy, glass-walled therapy session. Dr. Vegas, hidden, watches as Kitty's long hair brushes against her sisters' skin while she fingers their shaved pussies. They moan, taking turns riding Jack's cock in cowgirl and reverse-cowgirl positions. Athena, now confident, joins, fucking his sisters in doggie and missionary. Kitty licks her sisters' pussies, making them cum before taking a thick, satisfying cumshot. The doctor, satisfied with their progress, ends the session, leaving them to their newfound, incestuous bliss.
