Prisoner of the mind

"Ah, that is where the fun part comes in. You see, you have a whole heap of post hypnotic commands installed in your pretty new head. All I have to do is utter a few words here or a phrase there and I can quite literally have you jumping through hoops. There is just one or two little things we need to do before I untie you and then we can go out for a while together to see some of your old friends, and the first is..."
Sliding around the foot of the bed, Karen reached down and pushed a button on the control device. Not having seen it from his bound position, Jon was more than a trifle startled when he felt a warm, humming sensation eminating from his crotch. "Mistress, what are you doing Mistress?" asked a confused Jon.
"Oh, just getting you ready for our trip out," answered Karen, in such a way as to explain very little. "Jon, BURN MODE," Karen commanded.
Jon's eyes instantly glazed over, "BURN MODE ACTIVATED MISTRESS." Moments later, then seemed to return to their normal lustre.
Karen, still holding the control in her hand, simply pushed the button a few more times, then let it drop from her fingers. Turned and took a seat to watch the show.
Meanwhile, the humming from Jon's privates, raised in pitch to become an intense buzzing. It seemed to Jon that whatever Karen had turned on there, she had managed to turn him on as well. In no time flat, Jon was wrything and squirming on the bed as the vibrating penis inside him aroused him quickly beyond the point of endurance.
There was no way that Jon wanted to climax in this body, but it seemed that whoever has devised the stimulation device in his rubber panties, had managed to make it impossible for him to not do so.
Very soon, wave after wave of stress, followed by release, flowed up and down his helpless young body. At first the feelings were intensely pleasurable, but all too soon they crossed a line to become excruciatingly painful.
Jon was in the throws of his very first female orgasm, and it turned out to be some sort of super sized multiple climax. Jon tried once again to desperately get his hands down to his throbbing vagina, in order to stop these foreign feelings. But his hands remained firmly tied.
His knees slapped together, but that served no practical purpose, other than to remind him that they were encased in the same latex rubber as his new sex. After an eternity, the intensity seemed to begin to dull down and Jon thought that Karen must have switched the device off.
However, instead all that had happened was that Jon was beginning to lose consciousness.
