She receives strict discipline and training every day under the pretext of training from the manager, but a young customer from a wealthy family takes a liking to her and as he repeatedly requests her, she begins to have special feelings for him... Her masochistic qualities begin to blossom as she undergoes deep throating education, upright dildo riding training, toe-crotch oral service, and back whipping.
