These Amateur housewives are completely immersed in the 'erotic master' who is called a masseur, and although they outwardly reject him, in Kokoro they end up accepting him. His delicate touch plays with their indecent places, and their hearts pound and their crotches get wet. Once their reason has been loosened, it is extremely difficult to regain it, so they let themselves go as they please and cum so hard they go mad. "Just cum inside me!!"
