A host owes 1 million yen. A guarantor for a debt her boyfriend took out, 1 million yen. The interest is Togo (50% in 10 days), and a woman trapped in a debt hell that only keeps increasing is kidnapped and taken to a quarry where she can't escape. She does physical labor during the day and serves a certain man at night. She works hard and repays 3,500 yen a day. The sweaty men who do physical labor, whenever their sexual desire is ignited, it's sex time. A machine vibrator that breaks concrete, accepts the situation, swallows a dick and gets fucked! She uses her body until her mind is empty, and at night she inserts raw dicks over and over again. This is heaven!
