A slave's training begins with a simple task: consume his protein shake. But in the hands of this merciless femdom, it's a trial of endurance and degradation. She paces him, pushing him to the brink of gagging, her voice a whip cracking with every "Drink!" His eyes water, his face flushes, yet he obeys, knowing the alternative is far worse. After all, he's not just drinking a shake; he's drinking his own humiliation, a bitter pill to swallow before the main course - her cum, his reward, his punishment.
