Though certainly not its intent, Slave Wages makes a persuasive case for using real dominants and submissives in these types of productions.  That's because the vid's five girls all come across as pretend doms and subs just going through the whipping and squealing motions.  On the plus side, the gals are all at least somewhat attractive and where they frolic is a sexy, elaborate dungeon.  The bottom line, however, is true S&M fans can do better.
