This documentary follows Chitose Yuki and her house-call service built around her spectacular J-cup tits. She uses her breasts to ease troubled clients’ stress and anxiety: a man who has lost his appetite gets to fondle and lick them until his desire returns, while a shut-in receives a nursing handjob that leaves him refreshed and ready to go outside again. It is an affectionate breast-service documentary devoted to putting smiles on men’s faces.
