In the dimly lit room, May, a demure 19-year-old, awaits her initiation into the mysterious U50 society. Her heart races as she hears footsteps approaching. The door creaks open, revealing a masked figure, her mentor for tonight's rituals. He's tall, muscular, and holds a mysterious black box. "Tonight, May," he whispers, "you'll experience things you never imagined." He unzips his pants, revealing his throbbing, uncut cock. May hesitates, then tentatively reaches out, her small hand wrapping around his shaft. Her mentor guides her, teaching her the art of pleasure and taboo.
