Helen had been under their control for about six weeks now and was beginning to get used to her continuous high level of arousal, caused by any touching or rubbing of her breasts or nipples.

At the start of the seventh week the nurse came in and said 'Good morning, I hope we are feeling well today, please remove your skirt and panties and lay down on the bed.'

As usual when the nurse wanted Helen to do something she was accompanied by one of the large guards. Helen stripped off her skirt and panties and laid down on the bed, as it would have been pointless to argue.

'Right, lift your knees up and drag your feet up by your buttocks, that's it, knees wide apart.'

With Helen in this position the nurse began to inspect her cunt and probe around to get her clit to erect.

'Hmm, small clit, but nicely formed, well we will soon sort this out. Cunt, not very tight, or deep but I'm sure we can sort that as well.' muttered the nurse. Helen started to worry as she listened to the nurse's mutterings as everything that had happened so far had not harmed her particularly, but had certainly changed her body.

'Please sit still, this injection may sting a bit' said the nurse as she reached behind herself and took up the syringe that the guard was offering to her. She then reached down to a point just above Helen's clitoral hood and injected the small amount of fluid into the area at the root of Helen's clitoris.

'That should have some interesting effects over the next few days.' said the nurse. She then reached around and took up another syringe, 'Please roll over so I can inject this and the other syringe into your behind.'

Helen felt the nurse inject her with two more injections and was then allowed to relax back over onto her back.

'Well, Helen, this next phase will see some more dramatic changes, the genetic material I have just introduced into your body will have some quite major effects on your body. The first one will cause your clit to become very elastic. It will become like a thermometer of your level of arousal until you learn to control it and also it will become very sensitive to pleasure, just like your breasts and nipples. One woman we modified could control her clit from 1 inch long to a huge 14 inches and from about a 1/4 of an inch thick up to about 3 inches. This level of control, though, takes months so just let it do what it wants to start with.'

'The second injection I gave you is to slow down the aging process of your skin by making it very silky soft and elastic, while at the same time making your body almost indestructible and elastic. In fact, in about two weeks time I could probably take a knife and stab you in the arm and as I withdrew the knife your body would repair itself so fast, that to the eye it would look as if your skin was simply resealing itself around the blade.'

'The last injection will affect your muscles, it was in fact a cocktail of genetic material and will make all your muscles about 3 to 4 hundred percent more efficient, so compared to the rest of us you will be able to perform until well after we would have given up due to fatigue. There will also be some changes to specific muscle groups in and around your vagina and also your tongue. These are likely to be the changes you notice first.'

Having listened to this, Helen was really worried. Here she was with a superb body shape, except for the oversized breasts, and her body was to be further modified! Why? 'Please, why are you doing this to me? What is it all for? This must be costing a fortune for these facilities and all these treatments.'

'The reason is that we have tried all these and a few more modifications on individual girls and women but you will be the first to have your whole body and mind conditioned as a new woman. You will be able to pleasure any other man, woman, or even animal to a level they would not be able to imagine. We wish to study how all this power, coupled to the pleasure you will also receive from the person you are giving the pleasure to, will affect your ability to live and perform within society. We expect that there will be major changes to how you will have to interact with everyone you meet. You have probably realised that your body is having an effect on everyone who comes into contact with you, even if they have a mask on to prevent them being affected by the enormous levels of pheromones you give off when you are aroused.'

The nurse continued to explain 'Eventually we hope you will be able to control all of your body so that you can walk about in public, but you will have to keep a tight reign on your arousal level', she giggled, 'or you may end up with people around you spontaneously having orgies.'

Helen was really worried now, as it was difficult enough as it was to not play with her breasts and nipples.

Things remained fairly uneventful for the next few days with Helen concentrating on not playing with her breasts. She also started to receive lessons from a female psychiatrist on how to divert her thoughts away from her pleasure points unless she wanted to deliberately allow her arousal level to rise. The psychiatrist taught her a number of mental exercises that she practices all day, even now, unless she wishes to have sex.

The first sign that anything was happening occurred when one of the domestic staff asked Helen whether she wanted tea or coffee with her breakfast and Helen replied, 'Covfee pleesh.' She tried again. 'Covfee pleesh', she again said as she realised her tongue seemed all wrong. Running quickly to the bathroom she poked out her tongue to see what was wrong and was astounded when it came out of her mouth at least five inches. 'Oh, my god what hab dhey done.' she exclaimed. She next tried to move her tongue back into her mouth which worked fine. She next spent a short while poking her tongue in and out and found that once she got used to it there were no problems.

Going back into the main room she saw the nurse had come in, 'I hear that the muscular changes have started to happen. Please poke out your tongue as far as it will come.'

'My, it is coming on nicely, it will probably be fully formed by tomorrow at I should guess about eight inches, nice', said the nurse.

'Whatb am I to do ffor speekin ass I can't talk propberlee', said Helen.

'Don't worry, all the others learnt how to talk again in a few hours of practice and had their normal speech back a few days after the changes had finished', said the nurse.

'What we need to do is start your muscle exercises from today', she continued, 'When you have finished breakfast the guards will bring in a chair device for you to sit in. You are to sit in this chair all the time you are in your room and not doing anything else. You will exercise in the chair for an hour and then we will take you to the gym so that you can begin to understand how much stronger and how much more endurance your body is now gaining.'

The nurse left and let Helen eat her breakfast, which she managed with some difficulty due to her enlarged tongue. She wondered where it all went and looked into the mirror to see if she could see. Her tongue seemed to go back into her throat somewhere out of sight.

After she came back out of the bathroom, there was the nurse again, standing beside a throne like chair, 'Take off your shorts and panties and come over here. Get onto the seat, placing this small rod into your vagina', said the nurse.

Helen removed the clothes and climbed onto the chair, inserting the small rod which felt like some sort of plastic. The rod was about 4 inches long and about 1/2 an inch in diameter. Helen having sat down with the rod inside of her watched as the nurse folded some wing like sections over Helen's lap, hiding her body from the waist down from sight.

'While you wait for the seat to start, you may wish to take off your blouse and bra, as you're about to have some fun', the nurse said with a slight smile on her face. 'In fact, you probably want to get yourself ready for some extreme pleasure! I've seen women faint from the pleasure this chair produces on it's first time.'

Helen looked at the nurse and decided she better do as she was told and started to remove her clothing. All of a sudden she felt the small rod move inside of her cunt. It felt as if it was growing longer and going deeper inside her. It also began to feel tighter as if it was swelling wider as well. This continued until Helen felt as if she couldn't take any more, she felt as if her cunt was stuffed to the point where any more would have been painful. After a few seconds to get used to this the rod started to vibrate. This almost causing an instant explosive orgasm, as Helen became aware of just how much more sensitive her cunt had become.

'Oh god! Please help! Oh! Oh! I'm coming! I'm coming! Agheeeeee! Oh! Oh! Ohhhhhhhhhhhhhhhh!' she cried as the pleasure built up higher and higher. The pleasure just built higher and higher without actually giving her that final release. 'Please let me come! it's too much! Ohhhhhhh! Help! Please! Oh! Aaghhhhh! God why! Its, Oh! Soooooo goood! Please let me come! Pleeeeaaase! Oh god what's that? Something touched my clit! Oh please touch it properly! Oh! Oh Ayeeeeeeeeeeeeeee!' screamed Helen as she finally came so hard that she passed out.

Some time later she came round and realised she was still in the chair, 'Oh god! it's still happening! Oh the rod! It's getting bigger again! Oh! It's so tight! Oh I'm going to come again! Oh please! My clit what's happening to it? I can feel something rubbing it's tip! Oh that's nice. I can squeeze my. Ohhh! my muscles and... Oh that's too much! My muscles and my clit throb! Oh that's ... Oh! Oh! I'm cominggggggggggggggg!' and again she passed out.

When Helen came to, she was laying on her bed.

'Wow, that was amazing! I've never felt anything like that. God I need that again! Look at my nipples, they feel like they are still throbbing. I have never felt more alive! My cunt and clit feel so good!' Saying this, Helen reached down to rub herself.

'Eeek! What's that?' she said sitting up and looking down. Sticking out from where her clit should be was a long appendage about 4 inches long and about 3/4 of an inch thick. 'What have you done to me?'

'Try squeezing your muscles again.'the nurse said.

Helen tried and gasped, 'Aghhh!' she screamed as the pleasure again throbbed through her clit as she collapsed back onto the bed. She thought she had seen her clit swell alarmingly as she collapsed back.

Regaining her composure, she lifted herself back up and again looked down between her tits at her clit, 'Please hold me while I do that again.' she asked the nurse.

Once the nurse was holding her she squeezed her muscles again and she saw her clit swell to about 7 inches long and out to 1 1/4 inches thick, as well as feeling the extreme pleasure that shot through her body. As she thrashed around in pleasure, she grabbed the nurse's face mask and pulled it off.

'Oh, god no', screamed the nurse as she breathed in a heady cocktail of Helen's pheromones.

Helen watched in amazement as the nurse's nipples popped up as if someone had switched an electric switch on. After only a few seconds there was an obvious wet patch on the nurses shorts between her legs. 'Please Helen, make love to me! Fuck me with your tongue! Fuck me with your clit! Do anything to me! Just please fuck me! Lick me!'

Helen watched, amazed at the sudden change from cool, calm nurse to gibbering, begging nymphomaniac.

'Ok, let me help you strip off. Then we can have some fun.' Helen said, making up her mind to see where this might lead. 'What shall I call you? What's your name?' asked Helen.

'I'm Julie. Please, please fuck me! I need you! Oh god, I've never felt like this! I love you! Just please, please fuck meeeeeeeee!' Julie screamed, as Helen rubbed her hand over Julie's nipple as she was stripped.

'Please just put something in me', screamed Julie as she was losing control.

Seeing that Julie couldn't wait any longer, Helen decided to try something. Maneuvering Julie onto her back, Helen got between her legs and positioned her clit at the entrance to Julie's cunt. 'Oh', moaned Helen as she felt the exquisite pleasure this contact brought.

Pushing gently she felt her clit slide into Julie's cunt, 'Oh, that feels great', shrieked Helen at the same time as Julie started gibbering again, mouthing sounds and words that made no sense.

Squeezing her muscles, Helen could feel her clit growing and growing, the pleasure just building more and more. 'Oh god Julie, if this is half as good for you as it is for me ... Oh, Oh, I'm building up to cum again, hold on tight! Something is happening to my clit! Oh god! Oh! Oh! Aaghhhhhhhhhhh!' screamed Helen, as Julie grabbed and started sucking on Helen's huge left nipple.

Helen didn't lose consciousness this time but did lose control. She started thrusting her hips back and forth. Thrusting her clit into Julie and at the same time squeezing her muscles. She could feel her clit going deeper and deeper into Julie. Her clit was also getting thicker and beginning to conform to the internal contours of Julie's body.

When she regained some semblance of control she realised that Julie was totally out of control. She had her arms and legs gripping tightly round Helen and was whimpering, 'Oh Helen! Don't stop! Don't stop!' over and over again. Her whole body was vibrating as what appeared to be every muscle in her body spasmed in time with her pleasure.

Helen, not totally in control herself and simply continued to explore the pleasure she was receiving while driving her hips back and forth between Julie's legs, while continuing to squeeze her muscles that controlled her wonderful clit. The level of pleasure just continued to climb and climb until eventually Helen had her last orgasm and passed out.

Waking up some time later Helen looked over to the clock and realised that 4 hours had passed since she had first laid down on the bed after being removed from the throne seat. Julie was cuddled up into her side and Helen could just make out her mumbling over and over. 'Oh Helen please! Oh Helen, please love me! Say that you will pleasure me again! Helen please, please.'

She was still totally out of it, but it was also obvious she was totally used up. Helen got up and retrieved Julie's face mask and refitted it to her face. Having done this, Helen left the bedroom and went into the main room to think.
