This feature of solo-femme segments has several segments which are really not more than a simple strip-tease and then a quick wave bye-bye to the camera. Other scenes have a couple of incredibly energetic and lusty women goin' whole hog after the big-O.
The one, unfortunate, common element to all of them is the incredibly horrible music - probably used to replace the voiced directions being shouted at the models while they were being taped.
IF you choose to see this, you'll probably enjoy it scads more if you TURN OF THE AUDIO - at least then it's a nice collection of pretty girls.
This is #3 in a series which I believe is at least up to #14 - in later titles they do manage to get rid of alot of the AWFUL music.
