Anastasia, the elder, has always been the responsible one, but tonight, she's driven by a primal urge she can't suppress. She watches Bella, her younger sister, sleep, her gaze drawn to the rise and fall of her chest, the way her blanket clings to her hips. Anastasia's fingers trace the wetness between her legs, her mind filled with forbidden thoughts. As if sensing her sister's gaze, Bella stirs, her eyes fluttering open. Anastasia freezes, but Bella doesn't shy away. Instead, she smiles, a wicked glint in her eye, and whispers, "I've been waiting for you to wake up."
