Looking for name, video, producer

This is an 8'53" fragment from a longer film about a shy and reluctant wife taken to a sex club for the first time by her husband. It can be found on a few porn sites under the ridiculous title "Her husband loses the bet They pay their debts in their own". It is a high quality production, with excellent lighting, direction and acting - better than 99.5% of all swinger videos. The language spoken seems to be Italian, badly overdubbed by Russian. I would be grateful for any information at all (name, actors, production company), and of course for any download or at least source link.
