Patients Flame and Angella Faith are jealous of the attention Sir Michael has been paying to submissive Heather Hart.  To enhance their training, he calls in specialist Porsche Lynn.  She forces Angela to watch while she stimulates Flame with dildos and a vibrator.  When Sir Michael finds out about the session, he punishes Porsche with a spanking and inverted suspension for her "German attitude."  Angella and Flame escape, so Sir Michael and Porsche punish Heather.

This video has a lot of snappy dialogue, with the best line belonging to Luc Wylder: "The most well-trained submissive needs no restraint at all."  All the women respond well to their punishments, and Luc dominates with quiet yet sadistic authority.  Even if you haven't seen the previous Defiance videos, you will probably want to add this one to your collection.
