When she first joined the company, Momoka was helped by her boss, Atsushi. She vowed that "serving this man is my duty," and she accepts both Atsushi's unreasonable orders and his cock with a smile. "Senpai, your personal onahole is right here, ready for you to cum," she says, spreading her pink, twitching pussy. By playing the role of the convenient woman, she offers her pussy for fucking during work and after overtime whenever he's turned on! "Of course, since I'm just an onahole, the inside is... for you." She also dutifully fills her mouth with his cock. Even though he's about to get married to his girlfriend... "Your girlfriend? It's okay... I'm just an onahole, so it's not cheating..." With her airheaded personality and a sensitive pussy that gets wet even though she's just an "onahole," he finds himself sinking deeper and deeper into her!
