Hey, Wally,
The scene isn't a DDF scene. It's actually from the film Sex Maniax (2008), scene 6 (11 min.). See Zafira's filmography at

It's an amazing scene, but it could have been even better if the director had helped Zafira by providing some context for her wonderful action, such as having a guy bound and gagged on a chair, sitting a few feet from her, prevented from touching, but unable to take his eyes off her. She's mesmerizing. Too bad she has virtually given up on modelling. Wish she'd make a come-back.
