Luna Rival, the younger sister, stumbles upon Abigail Mac and Xander's erotic bath time. Abigail, the stepmom, has Xander's thick cock in her mouth, her wet body pressed against his. Luna watches, entranced, as Xander's hands roam Abigail's curves, his cock throbbing with desire. Luna can't help but join in, her own body aching for touch. She climbs into the tub, her small hands contrasting with Abigail's full figure as they both pleasure Xander, their moans filling the air with a symphony of taboo lust.
