Dirty Blue

Original title: ＳＭ集団（ロウ）責め

A standard pinku-eiga entry from prolific cult director Hisayasu Sato, this softcore melodrama centers on a successful female magazine editor with a handsome fiancé. The good-looking, successful couple seems to be the picture of happiness, until the young woman meets a kinky dentist who helps her to discover the pleasures of pain.
