Veteran shemale trainer, Mariana Cordoba, takes a young sissy under her wing in a cramped, dimly-lit training room. The old hand demonstrates her expertise, stripping the sissy bare and admiring his budding curves. She strokes his growing cock, teaching him to appreciate his new body. The sissy, eager to please, mimics Mariana's movements, swelling with desire. The air thickens with the scent of sweat and sex as Mariana pushes the sissy's limits, transforming him into her perfect, obedient pupil.
