Widowed and grieving the loss of his wife, father-in-law Ryoichi worries his daughter-in-law Asami and her husband, who move back to his home. Asami looks forward to a peaceful life with her kind and gentle father-in-law while waiting for the movers to deliver their belongings. Once the boxes arrive, she changes into a light shirt and short shorts to help carry the items. As she works, sweat glistens under her arms, her chest sways, and her hips sway with each step—drawing lustful attention from the moving men and, increasingly, from Ryoichi himself. Unable to resist her allure, Ryoichi begins manipulating the movers, using them to satisfy his desire for Asami’s body, setting off a twisted chain of events filled with betrayal, shame, and forbidden lust.
