Husband's restructuring and illness. "Reina" has been supporting her husband hard because of her love, but she has been struggling to move forward and backward. Rena could only rely on her father-in-law who had a feud with her husband. Father-in-law demands Rena's body instead of assistance. At first, Rena reluctantly accepts it for her husband, but after tasting the climax many times with her father-in-law's aged female body groping and close contact, she gradually gets into the pleasures of the swamp.
