Rope and Breasts (1983)

What a taste it has. A paradise within hell. In a dark, stagnant basement, A peony blooms vividly on the masochist's white skin, then vanishes!!

A husband and wife are on the road doing a traveling BDSM show at various seedy locations. The wife is getting bored with the show and wants to quit. But while on tour in Kyoto a wealthy man and his proper looking wife invite them to do a private show. Little do they know that their stage routine is just child’s play compared to what the couple have in mind for them.
