A few weeks ago I bought a new toy for my slave Diane. A thrusting fuck machine. After a little work getting it mounted on the gyno table I tied her in and got it working, sliding a 9 inch thick dildo in and out of her pussy. I slowly turned the speed up until she was pulling at the restraints, begging me to turn it off and squirting at least 6 feet over and over.

I watched for over an hour as my sweet little submissive slave turning into a cursing, orgasm machine bargained to be released from the relentless mechanical pounding I was putting her through.

When I'd finally seen enough turned it off and released her, she was trembling from head to toe, barely able to stand and begging me not put her on it again.

Tonight I plan to have her riding it again. I love watching her distress as it pushes her into her uncomfortable pleasure zone.
