Need help finding a movie

I saw a movie 15 or so years back that had Mandingo in the tile I believe. I know it's not the one that is out there now it James Mason in it. This one I think had Maria Sartis but not sure. She was stripped to the waist and whipped. The Mistress of the Plantation had one of the black mandingo tied between two post and went on to have her way sit him. Just looking for the title or where I can buy it.
Thanks I'll keep this one but looking for the other one on cd. Method in my madness since it deals with IR in movies and I sneak them in on wife. Since it has a movie cd by a good producer she will watch. I like it when she gets hot in IR sceen in drum and mandingo.
