Vitamin turns porn star Harutani Miu’s fantasy of elegant, old-fashioned Japanese bondage and submission into a drama. Miu plays the live-in assistant and longtime mistress of faded ink painter Ichikawa Bokutaku. Impotent but intensely sadistic, he can only find inspiration by watching another man beautifully torment the woman he loves. Miu willingly remains because she craves his twisted desires. Already spread-eagled and restrained on the bed, she squirms as brushes tease her armpits and nipples. Ichikawa then orders his disciple Hatakeyama to continue while he paints her fragile body through orgasm after orgasm.
