Mia Kalifaa and Sebastian Prieto, cousins drawn together by family bonds and a simmering tension, find themselves alone in Mia's room. Sebastian's eyes linger on Mia's ample curves, her round ass, and he can't help but voice his desire. "What are you doing here, sobrina? I want to fuck you, let me fuck that big ass of yours, it's making me too horny," he growls. Mia, initially shocked, feels a spark ignite within her. She's never considered this taboo act, but Sebastian's words stir something primal in her. As they lock eyes, they both know they're one step away from crossing an unbreakable boundary.
