*Some time before*
Behind her, Christina heard the slightly creaking sound of the rubber wheels of a medical cart on the cold concrete floor of her classroom. Cristina recognized it unmistakably; the young woman hated that sound most of all. Christina realized what would happen next, the girl's body trembled in anticipation of what was to come, she was thrown into a fever. The girl turned her strictly shackled body as much as possible in an attempt to see what the loving Master had prepared for her. Christina was not mistaken, her instinct did not let the girl down, the absence of a permanent anal plug in the girl's trained ass made Christina think that the Master had prepared additional entertainment for her. Christina stared at the contents of the cart. The medical cart was loaded with all sorts of accessories and enema equipment. Christina's pussy got wet. Crap!!! Kitty lived her life and betrayed Christina, constantly showing the Master the lustful nature of the girl. Christina from shame wanted to fall into the ground. It was humiliating, but all she could do was moan pitifully into her huge gag in anticipation of the upcoming training session.
