The formula for this extravaganza of disingenuous female ejaculation? Talk to camera, masturbate, "squirt", suck cock that instantly appears in scene, get pussy eaten, fuck in a minimum of three positions, suck cock, a little anal, "squirt" again. Change girl. Wash, rinse, repeat until you have five scenes to put end-to-end.
The one bright spot is Olivia Saint, whose combination of innocent looks (the baby pink lingerie helps), sweet voice, and dirty mouth proves hot enough to overcome the formulaic fucking and tantalizing enough to watch through to the end.
