As the clock strikes midnight, Alex sneaks into his stepsister's room, careful not to wake her. He can't believe their parents' new rule: they have to share a bedroom now. He watches her sleep for a moment, admiring her youthful body under the thin nightgown. He gently removes her clothing, revealing her small, perfect breasts and tight little pussy. Without saying a word, he climbs into bed beside her and begins to passionately make love to her. Her body responds instinctively, even in her sleep, making moaning sounds that fuel his desire. They fuck like animals, their sweat and moans mixing together until they both reach their climaxes. As he releases his seed deep inside her, he whispers, "These are the new rules now, baby sister." She nods, her eyes fluttering shut as she squeezes her thighs tight around him in pleasure. "I'm ready to accept these new rules, brother," she pants, her body still shuddering with aftershocks of satisfaction.
