Self-bondage addict Paul is submissive to the core but deeply unfulfilled. He despairs of ever meeting a really sadistic woman who will give him the constant hard discipline that he craves. Then a chance meeting with an old friend brings him within the thrilling orbit of top professional dominatrix Mistress Nikki. Paul is stony broke and cannot possibly afford Nikki’s expensive services. She amazes him by saying that she’s prepared to discipline him regularly without charge – but only as long as he always does exactly as she instructs and never asks why she is doing what she’s doing for him. The stunning dominatrix goes on to discipline Paul frequently and in ever more kinky and deviant permutations. On one occasion she takes him to an outrageously uninhibited S&M club where she arranges for the Amazonian Strap-on Jane to use and abuse him. On another occasion she summons him to an anonymous hotel room where, bound and blindfolded, he is sexually tormented by a mystery assailant.
Paul has been thoroughly debauched by such experiences and wonders what perverted sexual adventure Nikki is going to devise for him next. He finds out with a vengeance when she hands him over to her friend, the ultra-sadistic Mistress Alicia. This truly formidable dominatrix keeps Paul locked in her dark dungeon where she submits him to constant heavy discipline. Too late he realises that everything that has happened to him has been part of a ruthless conspiracy and that he is now completely at the mercy of the ultimate Mistress of Torment.
