Christina is a true hero in the world of physical activity. Her days begin at dawn, when she defies the morning laziness. The master brings Christina to the gym, where, under the supervision of an experienced trainer, exhausting hours of training become part of her daily routine. The trainer does not allow the girl to be lazy - persistent pull-ups, uncompromising approaches to lifting dumbbells, draining cardio exercises - all these are her companions in the Master's quest for the best physical shape of his slave. Christina is a perfectly trained slave girl - she always trains completely naked, with the exception of an anal plug and steel bracelets. Christina is used to not experiencing embarrassment and shame. The whip in the hands of the trainer is an excellent tool for motivating Christina; it emphasizes her determination and perseverance to train until she sweats.
