A woman in a masturbation apartment, known for her promiscuous nature, is introverted but actually has a strong sex drive (she's not very noticeable at work). A junior female colleague from the same department and company lives in the same apartment building. On the day I took a sick day, she suddenly came to my room and, from beginning to end, used polite language and actively and greedily took advantage of me. (Tenma Yui UZU-040)

A seemingly introverted, erotic woman living in a masturbation apartment, despite always using polite language, uses a condescending attitude to vent her sexual desires. She particularly enjoys teasing men. She's a junior colleague, Ms. Xiao Nei, three years my junior, in the same department. She's very unassuming and has little presence at work. We happened to live in the same apartment building (the masturbation apartment), and we'd only chatted briefly at work. On the night I took a sick day, she suddenly visited my room. It seems she harbored a one-sided crush on me. Her behavior was forceful and direct, and I could only be teased by her.
