Momoka, helped by her boss Atsushi when she first joined, vowed to devote herself to him. She accepts his every unreasonable command and his cock with a smile. "Senpai, your personal onahole is right here." She plays the role of the perfect "convenience woman," offering her pussy during work or after overtime. Even though Atsushi has a girlfriend he's about to marry, she tells him it's fine because she's just a tool. Her ditzy personality and hyper-sensitive body make him addicted to her.
