A story about a woman in her 30s who is devoured by a newly graduated girl.

"Senpai, you're actually a virgin, aren't you?" Newly graduated female employee Momoka Onoda, who just joined the company this year. She's serious, friendly, petite, and cute (but has big breasts), making her quite popular in the office. Despite publicly stating she has a boyfriend, there are still many men who target Momoka. However, the male employee in charge of her training struggles with conversations with her. The reason is that he is currently 30 years old and, although he hides it, he is still a virgin. The more attractive the woman, the more he tends to feel intimidated. One night, after a company outing, the man finds himself alone with Momoka. With a drunken, flirtatious attitude, the new graduate claims she's missed the last train, and the virgin man, flustered, invites her to his home, knowing it could be sexual harassment... "Shall I take care of you? Your virginity, senpai." The moment they enter his room, Momoka reveals her hidden predatory nature. The virginity that the man has protected for 30 years is easily devoured and scattered by the younger, newly graduated woman, leading to a shameful yet pleasurable first experience. After that, the man is treated as a convenient sex friend by the younger woman who has a boyfriend. While his pride is hurt, he finds himself indulging in the allure of her youthful body like a well-fed dog...!? A slightly depraved love story between a hidden predatory new female employee and a hidden 30-year-old virgin.
