Kim sneaks into her step-sister Vivi's room, driven by an irresistible curiosity and desire. She finds Vivi's bras and can't help but bring them to her nose, inhaling her scent deeply and even going so far as to masturbate on her bed. Suddenly, Vivi walks in, catching Kim red-handed. Furious, Vivi pins Kim down, smuthering her with her boobs. "I'm going to teach you a lesson," Vivi promises. Kim struggles for air, embarrassed but turned on. Kim tries to talk her way out of it, but Vivi is having none of it. She holds her down, and Kim can't resist the temptation and starts licking Vivi's nipples. Vivi, taken aback by the sudden pleasure, decides to take control even further. She slides down, pressing her breasts against Kim's pussy, driving her wild. Vivi picks up the pace, her breasts slick with oil and Kim's juices, until Kim can't hold back any longer. She cums hard all over Vivi's tits. And with a satisfied smirk, Vivi kicks her step-sister out of her room, leaving her a quivering, satisfied mess. This is a lesson Kim won't forget. (Includes very minimal step-sister talk)
