A 7-year-old rental apartment building located just 7 minutes on foot from the station, offering convenient city access and well-equipped with furniture and appliances. The property manager harbors impure desires toward the female tenants. Obtaining the strictly guarded master key, he sneaks into their rooms. A woman in her mid-20s, appearing to be an office lady, returns home with her boyfriend and they happily share ice cream together. Suddenly, he receives an urgent call from work and hastily leaves. Watching him leave with a lonely expression, the woman is left alone. Seeking comfort, she begins using a vibrator to pleasure herself. At that moment, she drinks water laced with a drug, losing consciousness. The man then enters, fondling her extra large breasts and performing titty fuck on her.
