"Licking is humiliating, isn't it?" Mei, who has a strong personality, stubbornly refused to give a blowjob even when she had sex with her husband. One day, Mei starts working as a "secretary" for a certain company in order to get out of her cramped environment as a full-time housewife. What she was waiting for there was "licking entertainment" for her business partners, "licking service" in her president's office and a job beyond her imagination. However, she begins to feel pleasure in licking Mei, and she becomes a "licking guy" who licks even a man's anus.
