Mei Itsukai strongly believed blowjobs were humiliating and had always refused to use her mouth during sex with her husband. Exhausted by the monotonous life of a full-time housewife, she decided to take a new path as a secretary at a corporation. There, she discovered that unthinkable practices like "licking hospitality" for clients and "oral service" in the president's office were considered normal. Initially filled with disgust and confusion, Mei gradually began to feel pleasure from these acts. Eventually, she transformed into a complete "licking slave●," even going so far as to lick men's anuses.
