From Nikki Fatale at Hypnofantasy the Cause and Effect review

Cause and Effect as usual Nikki using her voice switches tones and annunciation so that the listener is kept off guard just enough so that the hypnotic effect delivers the cause that Nikki wants one to feel. The easy flowing script keeps the ears tuned and the mind slips away from a consious state and opens to the control that Nikki invisions. Trying to remember if it was five or nine things the mind was grasping before the blank moment came falling deeper. Once again thank You Nikki for offering such a stealth erotic adventure.
