Alexis came down and released both of us in the morning. We went upstairs to find Ma'am dressed in a smart business suit, typing away at her laptop.
"Morning Tom, morning Betty. I'm off to do some work for Steven. I'll be back sometime tomorrow so until then Alexis is in charge. Have fun!"
She shut the laptop, gave me a quick kiss and left. I looked at Alexis, she had a dangerous looking smile on her face. She looked at Betty.
"Right then slave, you have to continue your training. Becoming a perfect latex doll takes a lot of hard work. We can have some breakfast, then we will begin."
Before long Alexis told me to take Betty down to the dungeon and to secure her only by her wrists to the cross. A few minutes later she appeared with an armful of black, shiny latex, and a few other items.
Betty was looking flushed, she was obviously aroused by what was going to happen. Alexis passed me the keys and told me to unlock Betty, she definitely was aroused already, that was obvious when the belt came off.
"First things first, get this little bit of kit on her."
I took what initially looked like a jumble of rubber cables. They were about half an Inch in diameter and fairly firm. However what I couldn't miss were the two dildoes attached to the cable. They were made of soft rubber but were both quite sizable and one was bigger than the other.
There was also a small round metal plate stuck on the cable.
"You can imagine what happens next Tom, use this lube on the smaller one and put the larger one in her pussy."
I had to slide them home in unison, Betty resisted the anal dildo briefly but soon they were both in position and I noticed that the metal plate settled perfectly over her clit, pressing down on it.
I pulled the cable tight between her legs and secured it around her waist. Betty was breathing more quickly now as the double intrusion filled her completely.
Alexis had a quick look.
"Perfect, now for her catsuit. It's chlorinated so it should slip on quite easily."
Picking one foot up after the other, I slowly and carefully pulled the tight latex up her legs and up over her arse.
"Make sure it's nice and tight Tom."
I pulled firmly up until the latex was tight between her legs and the rear seam was nestled between her cheeks. The suit has a rear zip that ran from the small of her back up to her neck.
Alexis had to release her arms now, and I pulled the sleeves up them.
"Stop there, I need to put these on her breasts before we go further."
Alexis had two thick rubber bands which she began to squeeze her breasts through. They were a tight fit but when she had finished the bands sat against Betty's torso and forced her full breasts out and up.
Alexis gave me a nod and I carried on. It took a few minutes to get each of Betty's fingers into the gloves but soon enough I had the latex up and over her shoulders.
I moved behind her pulled the suit tight across her back and zipped her up. What I hadn't seen were the two reinforced holes on the chest area, Alexis was busy getting them in the right place so that Betty's nipples poked proudly through them.
Next Alexis produced a thick and stiff looking corset. She held it in position from the front as I pulled on the strings and got it really tight, at least I thought I did.
"Come on Tom, put your back into it, her waist needs to be another inch smaller than that."
I kept pulling and tightening until Alexis was satisfied. By the time I had finished Betty was forced into taking short breaths and each one made her breasts push forward in a rather delicious way.
"I'll do the next part Tom, on your knees slave."
Betty dropped down and Alexis tightly braided her hair into a thick rope. I understood why when Alexis produced a latex hood and pulled Betty's braid through a short pipe at the top. The hood was pulled over her head and zipped up tightly, it had eye, nose and mouth holes.
Betty was covered in latex now but Alexis was far from finished.
Next came a severe looking, steel neck collar. It was more of a brace really, shaped to fit tightly around Betty's neck. It prevented almost all head movement and made her keep her head high and forward.
Alexis grabbed a handful of leather straps and arranged them across Betty's head, I quickly realised that they were in fact a thick rubber bit gag that the straps locked in place. It seemed to be jammed deep in her mouth but Alexis managed to tighten it a little more, just to be sure, she said.
"Just a couple more things Tom, get Louise's arm binder."
As I found it, Alexis produced a pair of thigh length latex boots. The heels were five inches high. Alexis slipped them onto Betty's feet then instructed me to pull them up and zip them up.
Lastly the arm binder went on. Alexis was very thorough tightening it up, making sure there was no slack whatsoever in any of the laces and eventually, Betty was ready.
She looked absolutely stunning, a vision bound in tight latex. Drool was already starting to drip out of her wide open mouth. I was mesmerised by the rise and fall of her breasts as she breathed.
"Now for the interesting part Tom."
I looked at Alexis, she had a remote control in her hand.
"Both of the dildoes vibrate."
She gently twisted two knobs and I heard a faint buzzing sound. Betty let out a little moan and shifted slightly on her heels.
"That little metal pad on her clit doesn't vibrate, it's actually a small TENS unit. At a low setting, it gives a delicious and rather erotic tingle. But as the voltage increases, it stops being so much fun, doesn't it slave?"
Betty nodded as best she could.
Alexis turned the last knobs and Betty made a deep groan. Her breathing quickly accelerated as her clit was bombarded by a tingling current.
"See this button here Tom, press and hold that."
I took the remote, and my thumb hovered over the button. I was pretty sure that Betty wasn't going to like what happened next as her moan had gone up a couple of octaves.
I pressed it.
Betty let out a muffled shriek and nearly lost her balance. I had only held it down for half a second but it clearly gave Betty's clit an agonising jolt of electricity. She was breathing hard, short sharp breaths as she recovered. The pad was still sending good feelings into her clit though, and the intruders were still vibrating.
"Betty is learning how to walk properly in her heels Tom. We are going to watch her walk round the dungeon. I will tell you what we are looking for. Good behavior is rewarded, bad behaviour is punished.
"Walk on."
Betty hesitantly started, walking around the outside of the room.
"We are looking for a nice balanced and confident stride. Each stride should be the same length, no hesitation, no wobbling. We also want it to be as sexy as possible, which means lots of lovely hip sway. Watch her. Just go round once slave."
I took in the lovely sight as Betty struggled around the dungeon. She managed a few steps in a row properly, but it was clearly very tricky. She had no use of her arms to help her balance and couldn't even look down.
She stopped next to us, Alexis looked disappointed.
"You will have to do a lot better than that slave."
She turned the current going to the pad off and slowed the vibrations as well. Then she hit the button and held it for about two seconds. Betty shrieked again, she tried to bend forwards in a pointless attempt to stop the pain and nearly fell over.
Alexis let go of the button and Betty straightened up, moaning quietly and taking quick breaths as she tried to recover from the shock.
"Again, walk on. Two laps."
She was slightly better this time, there was even a nice bit of arse sway occasionally. She had one little wobble just at the end though.
She stopped and Alexis hit the button again for another two seconds and I watched as Betty struggled to stay upright.
"A little better."
She was rewarded with some gentle vibrations and a little tingle on her clit. I wondered if that would actually help or hinder her attempts to walk properly.
"Three laps, begin."
As Betty struggled around the dungeon Alexis either increased the sensations she was receiving, or lessened them, depending on how she performed.
By the time she stopped she had earned a little more reward and was clearly feeling quite aroused.
Alexis passed me the control.
"Work her hard Tom. I'll see the pair of you in a while. Do not go soft on her!"
She sounded very serious with that last command.
"Thank you Alexis, I will punish and reward properly, I promise."
"Enjoy slave, I expect to see a much higher standard when I come back."
Alexis went up the stairs and I looked at Betty. My cock was thumping away under the belt, she looked amazing, if now slightly distressed. It occurred to me that I was getting turned on by the prospect of being in charge, and of causing her pleasure and pain.
"Walk on Betty. Three laps."
I watched her intently as she made her way around the dungeon. I gave her a little bit of pleasure through the dildoes but overall I felt she hadn't done a very good job. I decided to nip in the bud any idea she might have that I would be kinder than Alexis.
"That was not good enough Betty, and you know it. Don't you?"
She lowered her eyes and nodded as best she could. I depressed the button for a second. She managed not to scream but there was a low controlled hiss of breath and she shook slightly. I let her have another second, she hadn't expected that and this time a got a shriek of surprised pain. The third second had her trying to double up. When she stood up straight, I made sure that I was standing directly in front of her and looking into her eyes.
"You will improve or you will pay the price. I gave Alexis my word and I don't intend to break it."
