F-machine training in gym kit - HD

In my white knee-high school socks and gym plimsolls, you lock my ankles into spreader bars and gag my mouth to suppress my moans.  raising my legs high in the air i am hopelessly exposed to your gaze, but it does not end there.  you order me to set the f-machine to penetrate my exposed pussy, pumping away faster and faster until i cannot help but suffer the humiliation of an enforced orgasm in front of you, pleasure of the f-machine.  how i blush!
