Gym Foursome

You are one of the most successful and experienced private trainers out there, but sometimes even you can be surprised. When you accepted to train three spoiled, beautiful young ladies in your gym, you didn't know that their enthusiasm may cover something else that a wish for a pretty body. But one day, when you return unexpectedly, you see something you haven';t seen before: the three having their own, private "workout"; that involves some really naughty exercises. Still, what kind of a trainer you would be if you have't offered your help to them?
