A 7-year-old rental apartment located a 7-minute walk from the station, close to the city center with fully furnished living amenities. A man working for the popular management company holds a master passkey, strictly stored and secured. He begins malicious actions, sneaking into the women's rooms. An estimated 25-year-old office lady returns home and starts phone sex with her boyfriend while still in her suit. Guided by the voice on the phone, she receives sexual stimulation and loses consciousness. After drinking a beverage that suddenly makes her thirsty, she is overwhelmed by intense drowsiness and collapses. The man hiding in the bathroom starts teasing the unconscious woman's body. He gropes her beautiful, swaying big tits and thoroughly plays with her still-wet genitals.
