IMDB

Nikkatsu Romano Porno starring Naomi Tani. In this one she plays a bored and sexually frustrated housewife who runs into an old friend whose husband is an artist specializing in paintings of women in bondage. The plot unfolds just as you'd imagine, only with more (simulated) dog on woman sex than usual. This is not a good movie for sensitive souls. However perverse the film is, though, its "message" is essentially conservative, as Tani and her husband gain a new appreciation of one another through candles, crucifixion, and canine play. S/M is a sort of couple's therapy, and their marriage is saved. Would Dr. Phil approve?
(Description stolen from elsewhere)

I must admit I love submissive women. Sexual submission totally turns me on. In that regard, this japanese softcore delivers big time. Pretty wife is bound and tickled then made to pee in a bucket, then she is made to wear a collar and walk on all four naked and eat dog food (not to mention some activity with a real dog!) and there are more, just watch the clip. All of this is perversely erotic and presented in beautiful widescreen cinematography.
Rope Cosmetology is certainly one of the greatest examples of the genre.
Highly recommended.
