In the quiet of her niece's room, Aunt Cass finds herself alone with a sinful curiosity. She slides her hand along the leather-bound copy of 'Demon Slayer', feeling a forbidden thrill. As she opens the book, her eyes widen at the explicit illustrations, her heart pounding as she imagines the demon's powerful form. Her hand wanders, lifting her skirt, fingers finding her wet, aching center. She strokes herself, fantasizing about the demon's touch, his massive cock stretching her, his grunts of pleasure echoing in her mind. Her climax is intense, leaving her breathless and ashamed, but also yearning for more.
