Big name porn stars populate this bondage video, definitely softcore but still with some edginess with full nudity.
Lauren Brice plays the tall dominatrix who metes out plenty of punishment unemotionally -she's confident and in charge. Nominal story content features P. J. Sparxx and Trixie Tyler doing research for a book about female sex slaves, and we watch in flashback scenes depicting Brice and her slaves in action.
Shelby Stevens, very early in her career before she became a makeup artist, and an obscure player named Cie Cie, play the slaves. It's worth waiting for a fine ending that rounds out the story properly.
