Rika is confined to a dangerous contractor's room in order to get an extension on her fiance's debt repayment. She was meant to endure until her lover returned with the money, but... Rika loves semen so much that she masturbates out of longing for dick juice. A dishonest contractor sees this and takes advantage of her, so she gives in to him in exchange for a reduction in the debt. The men's torture becomes more intense, and she gags with a deep throat blowjob, and turns into a slut who drinks semen covered in saliva.
