Name of 70s/80s Medieval Porn Movie

This is a long shot, but I'll try my best. Obviously the image I used isn't an image from the movie. I'm looking for the name of this film if possible.

I remember it featured what I could only best describe as Greyfriars Franciscan Monks in some sort of medieval times. It MAY have featured nuns. I remember they had sex in what looked like a barn in the woods. There was also a scene that took place in the actual woods.

Very classic. Possibly 70s/80s. A friend once told me it was called 'The Pink Pussy' and it may have been French. I searched for that but nothing came up so probably isn't called that. But it could be French (Franciscan Monks after all). I wouldn't rule out Italian either.

I don't recall any technology (phones, cars etc) being used. This is why I think it may have been medieval times.

Any help is much appreciated.

Thanks
