This is a porno version of the classic tale by Jean Paul Laurens. Now the version I watched was in Italian so I can't really give you a detailed description other then there's a lot of fucking and it obviously is about a guy who sells his soul to the Devil, so... Its pretty well done with a decent budget and hot ladies so take a gander here and see it you gleaned anything else from it.
The Devil is a bastard!!
Doesn't seem like that bad of a deal to me.
