Ultimate shoulder rides

The first clip is really ecellent.
Thank you.
But as a riding instructor I have to say, that Mistress Bijou is riding much more better and really professional.
The lady in the clip is not sitting upright with her backbone and she is not working with her thighs and so I think she has not much riding experience.
Real riders are working with their thighs and weight.
But the pictures are very good!
