Italian director Joe D'Amato, mostly known for horror movies produced on a budget that wouldn't get you a pair of Nyke sneakers at a ghetto flea market, gave us one of the best examples of nunsploitation. (I'm using the word "best" in the same way you'd use it to describe the different shits you see in a zoo. Like "The elephant clearly has the best shit, it can bury a man whole.")
I found a 15-minute clip on YouTube and was surprised because I didn't think there were 15 minutes in this movie that didn't feature nudity. I was surprised again to discover that there aren't, and you can see naked nuns on YouTube, apparently. I checked with the bosses at Cracked and they watched the clip and then told me to find them more clips and a bottle of white wine. Then they told me I was pretty and my mouth was the sort of mouth built for kissing and other naughty things, some other stuff happened, and, long story short, I couldn't use that clip.
Even the box art is chock-full of nudity, but at a more acceptable level. It calls this the most explicit nunsploitation film ever made, but it's not that it's full-on nun porn (there is a bit of full-on nun porn, but it's not the whole movie) so much as they just never stay clothed. And even when they are clothed, like in a nun's habit, they have boobie panels cut out. There's also some demon possession, because of course there is.
