F-machine training!

It has been a while since i have been able to play on my f-machine, so when the opportunity arose i was determined to really enjoy it.  i kneel down, part my legs and take it, slowly at first before speeding it up.  i soon need to spice it up, however, placing an open-mouth gag in my mouth.  my mouth is so vulnerable....would you use it whilst i was being stretched from behind by the machine?  to spice it up further i remove the gag and cuff my hands, rendering myself held in position for the machine's relentless pumelling.  finally, i really spice it up by reddening my bottom, with a wooden spoon and my hand! filmed using two angles, you are treated to my reactions and the machine's ministrations as i complete my training session of submission on the machine.  am i ready to serve?
