A galvanizing experience

MacKenzie was naked, and to make things worse, there was no way for her to cover herself, and her hands were chained above her head. Her nudity and helplessness were made worse as Willow was dressed in a white lab coat, showing off her freedom to move around MacKenzie and 'encourage' her to keep moving towards the sinister looking table, with straps attached to its surface, with little spanks, or tugs to her nipples, or pinches or tickles. All these reminded MacKenzie of how naked and **** she was, and how obvious her arousal was. She was **** to cum, and she knew that her only hope of that happening was complete obedience.

Willow too was aroused, but she could hide that behind a lab coat and an facade of scientific detachment.

The table was quite high, at a convenient level for the scientist, not the specimen, but MacKenzie managed to sit on it with a combination of pulling herself up by her chains and some 'help' from Willow. Under other circumstances she might have complained about grabby hands, but at the moment she welcomed Willow's touch.

Under Willow's direction MacKenzie lay on her back with her arms out and elbows about level with her ears, and did not resist as Willow strapped her down with straps just outside her shoulders, and just before her elbows. Willow then released MacKenzie's right wrist from the chain, and fastened it above her head with strap around her wrist. MacKenzie was distracted by Willow's closeness as she leant over to fasten the strap, her hair tickling MacKenzie's breasts, and her face close to MacKenzie, who would have kissed her if she had not been strapped down so firmly.

Willow broke MacKenzie's compliant mood with a sudden tickle attack on her armpits, saying 'I will do this again once your left hand is in place and there is nothing you can do to stop me' with a mad scientist cackle. She released MacKenzie's left wrist from the chain, and the outcome of the subsequent arm wrestle was never in doubt. Mackensie's movements were restricted anyway by her upper arm already being fastened down, and Willow not only had two hands free and no compunction about using them, but could use her body weight to hold MacKenzie's arm in place while Willow fastened the wrist strap. MacKenzie could feel the shape of Willow's breasts through the lab coat, her only garment - an unnecessary reminder of the femininity of her captor.

As promised Willow tickled MacKenzie's armpits mercilessly, only occasionally straying to include her breasts, while MacKenzie waved her legs around uselessly, and begged breathlessly for mercy. The table was quite short, only coming to the middle of MacKenzie's thighs so she had plenty of space to wave her legs.

'I will stop when your legs are spread wide with your heels touching your bottom' Willow declared, and MacKenzie complied immediately.

Willow fastened a narrow leather strap with a D ring around each of Mackensie's legs, just below the knee. She then used broader straps round thigh and lower leg to enforce the heel near bottom instruction, and stepped back to admire her work.

'You look like a little froggie' Willow said, 'all spread out, cute and helpless. You are just right for the experiment I had in mind - remember our science classes ?'

For an instant MacKenzie had a memory of a picture in a text book of a frog, spread out as she was, but dead and fastened down with pins and about to be dissected. Her look of horror made Willow smile reassuringly, and then gently stroke MacKenzie between her legs. Her smile turned into a frown as MacKenzie started to close her legs, and then back into a smile as she opened them again. 'Oh no - I can have much more fun with you like this - I was not thinking of that. Do you remember some Italian guy, he had a wife who was into science too, and they found that they could make a frog's leg kick using electrical stimulation. I had the idea to try experimenting with different kinds of stimulation'.

'Here !', Willow tickled MacKenzie between her legs - Willow's fingers maddenly good at taking MacKenzie to the edge, but not beyond, and again MacKenzie's legs closed, whether to try to stop or enhance the sensation she could not tell.

'Keep them open !' Willow ordered, but a touch from her expert fingers caused visible twitch from MacKenzie, who responded 'I am trying, but I can't'.

'This will help you try harder' - Willow fastened something to the table to the right of MacKenzie's right breast. It looked like a table tennis racket, standing up vertically, and appeared to be attached to some kind of hinge. The position looked ominous to MacKenzie, even more so when Willow released some kind of catch and the paddle snapped forwards. To MacKenzie's temporary relief it was instantly stopped by Willow, but that was only so that she could adjust it so that it would land exactly on MacKenzie's breast, and the treacherous nipple which was standing even firmer from the sensation of the little rubber pips moving over it as Willow made the adjustments. The process was repeated on MacKenzie's left side.

'Pay attention' said Willow in her best science explanation voice. 'When this string is pulled ...' she indicated a string at the base of the mechanism, and then pulled it. The racket delivered a painful whack to MacKenzie's breast. The racket then returned to the vertical, ready to strike again.

'Oww' MacKenzie cried 'Please don't pull the string again.'

'I am not going to', Willow responded, 'but you might - Legs open wide !'. She tied strings which MacKenzie assumed, correctly, were attached to the racket mechanisms, to the D rings on the straps round MacKenzie's legs just below her knees. Now if MacKenzie failed to keep her legs apart as required she would whack her own breasts.

Walking to the bottom of the table, for the best possible view and access, Willow smiled at MacKenzie, and then touched her gently between her legs. Wack ! Willow waited for MacKenzie to recover, and to look at her nervously and then stroke.. Wack again.

After this had gone on for a while MacKenzie found that deliberately opening her legs further as Willow's hand approached allowed her to escape having her breasts punished. The problem was that it felt like a surrender - she was deliberately submitting to Willow, which would not be so bad, except that Willows touch was rewarding this behaviour and MacKenzie was finding the very idea of surrendering to Willow exciting. Willow had to be careful not to allow her to go over the edge.

Once MacKenzie could be touched, with care, without punishing herself Willow upped the stakes, teasing MacKenzie with a stiff feather, and telling her to try harder until MacKenzie mastered the feather too.

'Good - now we are ready to start the experiment' declared Willow. 'Start !!' the startled MacKenzie replied 'We have been going on for ages !'.

'No that was just getting you ready' Willow replied. 'You can control your legs, and decide if you want to close them or not - the experiment is to find out my control can be greater than yours' She fetched a small trolley with a device like a big glass wheel and a crank, and some coils and wires leading from it, and attached stuck pads on the ends of the wires to some sensitive parts of MacKenzie's anatomy.

'Try to keep your legs open' said Willow, turning the crank very slowly. MacKenzie felt a strange tickling sensation, and her legs wanting to close, she fought it, Willow turned the crank slightly faster and Whack.

MacKenzie tried to fight the sensation, but when Willow turned the handle her legs were no longer her own. She did not want to whack her breasts, but Willow's control was greater than hers. When Willow used her fingers or the feather MacKenzie could resist, but the galvanic machine was irresistible.

MacKenzie did not know at the time, but this but this was the first step towards Willow's development of the **** Collar, and the army of collared **** girls, who under the control of the collars would capture, strip, bind and collar more and more girls (or collar and order to strip, or various permutations) and MacKenzie would

* Be one of the first captives

* Become a key figure in the resistance, finally succeeding or failing

* Sit by Willow's side as Joint Empress of the World.

All that was far in the future, and the sound of running feet outside the door heralded the arrival of ...
