Katrin comes from the stable and meet her slave lieing on a gymnastic ball.
Ready for a ride! He must feel, what the horse is feeling when Katrins bounnces with her heavy ass.
She decends foreward on his chest and soon, after some high bouncers, she lands on his face.
His face is a good saddle and must be ridden.
For riding back, she turns around and sits reverse on his face.
