Eternally beautiful, perky Nina Hartley disciplines her latest round of pretty female slaves. First she lets chained sub Anna Mills eat her pussy, whips her with various implements and hooks her up to the Thrillhammer, an impressive slow-action fucking machine with an attached dildo.
Mistress Natasha Sweet stops by to flog Claire Adams while she's pressed against Nina; Mills returns for nipple and clit suction play and teasing with the electrical wand. For the finale, Sarah Blake gets hung upside down, flogged, treated to the Thrillhammer, and masturbates to orgasm while Nina thumps her chest with big padded gloves.
Moody lighting, interesting torture tools, and Nina herself elevate this collection of scenes well above average. However, the box advertises "supplemental material" and a photo gallery, neither of which are anywhere to be found on the DVD.
