For a second I thought this was your typical porn version of S&M but these are clearly Bondage and Dominance models they are paid but they specialize in this. Regular sex workers wouldn't. Best scene is when the top has the sub suspended from a bar upside down she rips open her own pantyhose and shoves the subs face in her ass while she vibes her own clit to orgasm. Now that is S&M!
SO MUCH MORE COULD HAVE BEEN DONE!
