Anybody know where I can find the full movie?

I'm desperately trying to find the full film from which this clip is from. It was one of the first porno's I ever watched back in the day. It's taken me weeks just to find this clip but it's the same clip on every site and with no details of it's source or the performers. As I don't know the names of any of the performers, I've nothing to really go on. Thanks
