Built seven years ago and located just seven minutes on foot from the station, this rental apartment offers convenient city living with fully furnished rooms and appliances. A man employed by the popular management company gets his hands on the strictly guarded master key and begins sneaking into the rooms of female tenants. An office lady returns home looking exhausted, startled by a call from her subordinate. After being scolded over the phone, she immediately starts preparing to head out again. While changing clothes and gathering her things, she accidentally drinks water laced with a drug and quickly loses consciousness. The man crawls out from under the bed and, taking advantage of her helpless state, fondles her big tits and thoroughly enjoys every inch of her voluptuous body before raping her.
