From Model to Lust Object: Nina

--

This story is a few months later in time than the earlier Lust Object Gym stories where Anna joined. By the time Nina comes into play, the trainer at the gym met Anna's friend with benefits from back home. They get along very well and their style of training the girls is very similar.

After a while, the trainer asked Tom (Anna's FwB) to join him as the second trainer at the gym so they can handle the rising number of members and sponsors better. Most of the shows are now 3 or 4 members performing rather than the 1 or 2 before.

This story is about a new recruit, the inexperienced but eager Nina, who gets introduced to the trainer by Number 9 after a photoshoot at her studio.

--

Curious Nina

The first part of Nina's shoot had been very much what she had hoped it to be. Pretty dresses, bright smiles, superb makeup, everything she had imagined it would be like to be a supermodel. Her brothers knew she had always wanted to be a model when she grew up, and they had given her the full model experience for her 21st birthday, with a visit to the beauty saloon followed by a high end photoshoot. These were the sort of shoots that Number 9 loved to do. Nina was obviously a girl who could have been a model, perfect pale skin, shoulder-length blonde hair, large bright blue eyes, long thin legs, a perfectly round bottom, flat belly, ample breasts and a beautiful, symmetrical face.

Number 9 quickly sent her brothers home when she saw how Nina stayed very shy in their presence. As soon as the boys were gone, she clearly opened up, starting to really enjoy her dream-shoot. Her whole body started radiating her enthusiasm, and Number 9 surely was a master in capturing that radiation.

After a few of her own dresses, Number 9 suggested they'd have a look at the rather extensive collection of dresses at the studio. Nina loved what she saw, and automatically took to some of the more revealing dresses. She was also peeking at the many pieces of sexy lingerie hanging in between the other clothes. When Number 9 saw her check out some of those sets, she remarked that they could do some pictures that would not be part of the official shoot and hence would never make their way to her family, just in case she wanted to try some more sexy pictures.

Nina smiled when she heard that, she seemed ready for some mischief. Number 9 helped her pick out a couple lingerie sets that would suit her pale skin nicely. She didn't have to convince her towards the revealing stuff, Nina clearly preferred the sexiest sets. They ended up with a set in very thin black lace, very much see-through, and another one that was even more revealing with a half-cup bra that would surely show her nipples.

After a bunch of pictures in those, including some rather sexual poses with for example her hand in her tiny thong, Nina put a dressing gown over the half-cup lingerie and they went back to the clothes racks together. Number 9 suggested having a look at the more erotic clothing in the back, which also held a whole bunch of BDSM stuff, next to latex and leather clothes.

"You're sure my family won't see those, right?"

"Absolutely Nina, no worries. You're certainly not the first girl to come here and shoot some stuff that's not suitable for parents," Number 9 smiled.

"I.. I like some of those... But they look so much like porn-stuff. Not sure I want to go that way..." Nina said hesitantly.

"Oh, I won't lie to you. That's certainly possible with lots of those things. We can do cheap-looking porn if you'd like to, but in my opinion that's indeed not, well, YOU. I had some more classy pics in mind."

"Yeah, let's leave the cheap porn for some other time," Nina laughed uncomfortably.

"I could show you a few examples of what I had in mind if you want."

Before Number 9 could finish that sentence, Nina was already nodding, "Yes! Good idea."

"These aren't pictures I made though. But there's a good reason for that," Number 9 smiled brightly while grabbing a folder from the cabinet at the other side of the room.

"Oh?"

"You'll see..."

Number 9 opened the folder, with a large "9" written on the outside and looked at Nina while her face turned a bit red.

"That.. That's you!"

Nina was staring at the print of a picture of Number 9, kneeling topless on a concrete floor with her hands behind her head, her legs slightly spread, back perfectly straight, with a blindfold on her eyes and a ballgag in her mouth. On her nipples were clamps and a subtle stream of drool was leaking from one corner of her mouth.

"Oh, sorry, I didn't want to shock you! Sorry! Yes, indeed, that's me..."

"No no! It's an amazing picture! I love it! And I love how fabulous you look!"

Nina looked at Number 9, then back at the picture.

"Wow! Just wow! Yes, I think I want this as well! Can I see more? Are these all pictures of you?"

"Errrr, yes, and yes."

Nina browsed through the pictures of Number 9 in action. The next picture showed just a silhouette of Number 9, shot from behind her, standing entirely naked except for high heels under a majestic tree in the sunset. Her wrists were tied high above her head to a branch of the tree. Then there was a picture where she was crawling in sexy lingerie and high heels, with a leash hanging from a black leather collar, her back arched back and her bottom in the air. She kept a riding crop in her mouth. The next one had Number 9 sitting up right on a bench with the picture taken downward over her shoulder, showing her widely spread legs in just a black lace thong. Several red stripes were showing on her thighs and the movement of a cane hitting her was showing beautifully.

Nina looked at Number 9 with a questioning look and open mouth.

"Yes, nothing in those pictures is fake. It's a bit of a hobby for me, a getaway from daily life so to say. Don't worry, nobody forces me to do those things, I genuinely enjoy the enormous intensity of those things."

Nina turned another page and she saw a picture of Number 9 together with another girl, both bending forward and kissing each other while there were little chains running between their nipples. Thick ropes were tied tightly around their bellies and then between their legs pulled upwards and backward, making it look like a very uncomfortable position.

"Are you a lesbian?"

Number 9 smiled, "No Nina, I'm bi, I can enjoy both men and girls as sexual partners, but my dominant partners are always men. I believe towards the back are a few pictures where I'm serving a man... Beware, that's a bit more like porn."

Nina immediately skipped to the end and saw a pair of pictures with Number 9 kneeling in between the legs of a man. In the first picture she was looking up towards him with her mouth wide open just in front of his rather sizeable and erect dick. The picture next to it still had her looking upwards toward him, but she had his entire dick in her mouth and throat.

"Wow. I see." She wasn't too sure what to say to this, but she felt like all this talk and looking at naked Number 9 made her a bit horny.

"Shall we keep it to the first few scenes for today?" Number 9 suggested with a smile.

"What the heck, why not? Let's do this! But not a word to my family, ok?"

"Obviously."

Demonstration with Number 9

Number 9 discussed her shoot with the trainer at the LO Gym. He asked her about specific preferences she had shown and in the end he told her to invite her over to watch a session between the two of them. "I have a new toy I'd like to try out and this might be the perfect opportunity" he had added.

So the evening after the shoot, Number 9 sent a message to Nina saying, "Sir will be at the studio for a session with me Friday evening at 9pm. He asked me to invite you to come observe. He's happy to answer any of your questions. I'd really love to see you there! If you come a little earlier you can help me pick my outfit ;-)"

Immediately she gets a text back saying, "But I don't know him at all!"

"I am 100% sure that he will be the perfect gentleman to you! You have my word! You can just watch and go away again if you don't like it or ask anything you want if you do like it :-)"

"I'll be honest, my mind says no, but my body screams yes! I can't decide!"

"I fully understand, believe me! I was the same the first session, but never looked back after that! Don't do it for him, do it for yourself (and maybe a tiny bit for me!)"

"I'll sleep on it!"

The next morning, a very short text: "Ok!"

"Oh cool! So happy! I'll be there at 8pm. Call me when you get there!"

8:01 she called. Number 9 let her in and showed her to the same studio that she had had her shoot in. Nina was wearing a little black dress, her nipple poking through the fabric, making it clear that she wasn't wearing a bra. She looked classy and sexy, with the tight dress highlighting her perfect body.

"Don't know why, but I tried to look sexy for him!" Nina announced immediately.

"Tried? You're looking absolutely stunning! That's not just sexy, that's sex radiating all over you!"

"Oh! Is it too much you think?" Nina asked, very uncertain of herself now. "Oh shit, I should have put on that bra!" She looked very unhappy all of a sudden.

Number 9 was quick to reassure her that she was all good, and that the trainer would certainly appreciate this much female beauty. "You'll make a very good first impression! He might never look at me any more, but that's ok!" she laughed Nina's stress away.

"I still have some stuff to prepare for him, would you like to pick out an outfit for me? I'll need lingerie and a dress that will impress him! Needs to be real good today with you around!"

Number 9 came back rolling two carts behind her, packed with BDSM toys. Nina looked surprised at the amount of toys, and even more surprised when 9 said, "Oh, there's more. I'll be right back with the other two carts!" And indeed, moments later she pulled in two more carts, packed with even more gear, all nicely arranged and sorted.

The two girls discussed a lot about the lingerie and dresses that Nina had picked out, which combination would be the ultimate perfect choice for the night. Finally they settled on a minimalistic black lace lingerie set including a half-cup bra, combined with a black tutu skirt and a very thin white top. The black high heeled leather ankle boots she was already wearing remained. Number 9 got to work on her makeup and Nina explored a bit more what all this equipment in the carts was for exactly.

It was about 8.40pm when they both heard the gate open in the back of the building. "It's him! Can't be anyone else!" Number 9 said, visibly getting a bit nervous. She wasn't entirely ready for him yet!

Indeed, shortly after the trainer walked into the studio, pushing a flightcase into the room. "Hello ladies," he said with a smile. "Oh, don't worry Number 9, I know I'm early, you can just finish getting ready, pretend I'm not here just yet. And you must be the amazing model my friend here told me about... Nice to meet you! Nina, right?"

He shook her hand and took a step back.

"Nice to meet you too, Sir," she responded in a very soft and timid voice.

"Can I assume that you are aware of the sort of things that we have planned for tonight?"

"Yes Sir."

"Can you briefly explain in your own words what you expect to see?"

"BDSM... She told me that she will have to obey all your orders and that you will play with her naked body. You will make her expose herself and do sexual things for you, and that you will cause her real pain. That she will be entirely at your mercy. That it will sometimes be extremely satisfying and sometimes be very painful. She also told me that you have a long list of all sorts of things that you can and cannot do with her, so that you already know what she wants or doesn't want to happen."

"Bravo, Nina. That's an impressive answer. I see you two have indeed been talking quite a bit. That is all entirely correct. I want to reiterate that last point. Yes, at times I will indeed do things to her or ask her to do things that many people would consider weird or bad, but it's important to know that I will never do, or ask her to do, anything that we haven't agreed on beforehand."

"I understand that Sir."

"Very well. With that out of the way, I understand that you would like to watch our session tonight, is that right?"

"Yes Sir, if that's ok with you."

"Don't worry Nina, that's entirely ok with me. Feel free to watch from anywhere you want, maybe I'll invite you closer to show you sometimes at some points, feel free to do so or remain where you are, it's all up to you. Of course, feel free to ask any questions you have at any time. There's not a bad time for questions. I'll always try to answer them as clearly and honestly as I can. "

"Thank you Sir, that's very nice of you."

"Happy to show you our nice little hobby Nina. Maybe one more question for you... do you mind if you would get to see me naked or partially naked tonight as well? I might want to ask a blowjob from our friend for example."

"I don't mind Sir."

"Ok then. I don't have any further questions. I'm all ears for your questions now."

She took a while before she answered with her question.

"Should I also maybe somehow act as your slave tonight Sir? I'm not too sure how to behave towards you."

He smiled.

"I see. No, not at all. Of course not. A little respect like you're already showing is appreciated, but compare that to how you would act towards the manager of one of your friends maybe. Does that make sense? I surely don't expect anything from you tonight, or later for that matter. I hope you will enjoy what you see tonight and where that might lead us is just speculation. Tonight you're just an observer. I'm happy to explain anything you're curious about. Remember, no wrong questions, no wrong time to ask them."

"Ok Sir, I think I understand. I can do that. Thanks."

"Any other questions right now?"

"No Sir."

He went back to the flightcase and started unpacking it. Nina nor Number 9 could really figure out what it was exactly. While he worked on that, he explained to Nina that what she was about to witness was not a beginner's session. That he knew what Number 9 could do and that he would expect an awful lot of her. He wanted Nina to understand that this wasn't the standard, this was a demonstration of the result of years and years of experience and working together in lots and lots of these sorts of sessions.

Once he was ready he asked Number 9 if she was ready as well.

"Yes Sir."

"Good. Get in position then."

Turning to Nina, he asked if she was ready to start. She nodded, already staring at Number 9 getting into her kneeling position on top of a similar sort of pedestal like at the gym. She didn't say anything and just waited for the trainer to address her.

"Hello Number 9."

"Good evening Sir."

He slowly walked around her, checking her dress and posture.

"Are you ready for our session Number 9?" he asked when he was right in front of her, with his face only a few centimetres from hers.

"I am Sir, will you please use me for your pleasure and entertainment tonight Sir?"

"I'd be happy to, Number 9. I see you picked out a nice little outfit, I like it."

"It was mostly Nina who picked the clothes Sir, I think she deserves the credit if you like it."

"Thanks Nina, you've got talent," he said to Nina with a smile. She was standing a few metres away, watching carefully.

He looked a little closer at Number 9's breasts. "I can't help but notice that your nipples seem to have more potential to show through that top. Don't you think you should have made sure to have them nicely erect for me?"

"I'm sorry Sir, of course you're right."

He grabbed her left breast through the top together with the half cup bra with one hand to hold it steady and grabbed the nipple with his other hand. He pinched it hard and twisted it around in both directions. You could clearly see the pain on her face. When he let go, her nipple was hard and he moved to the other.

"Now, that's better, don't you think?"

"Yes Sir, thank you for fixing my appearance."

He walked to one of the carts with equipment and took two pairs of clamps. "Normally I would put these on to make sure they will stay hard," he said waving a normal looking set of clamps, "but to make sure you remember next time, I'll use these today," waving the set of clamps in his other hand. Amazingly 'by chance' the exact same larger clamps as Nina had picked a few days earlier for her photo shoot with Number 9.

He pinched her nipples again and put the clamps on. While Nina had had trouble putting them on a few days earlier, struggling with the sharp pain in her nipples, Number 9 didn't move at all, staying in her position and accepting the pain with only her face contorted a bit in pain.

He glanced at Nina, who was watching intently, clearly recognising the nipple clamps. "Number 9 told me you had your picture taken with those on, do you remember how they feel?"

"Yes Sir, I remember vividly! It's incredible that she didn't move at all when you put them on!"

"Very true Nina, as I said before, I can't stress enough that this level of body control and obedience is exceptional and takes a lot of training. Of course, it's not realistic to expect that from a novice. If you ever decide to try a session yourself, I'll ask you to do your absolute best, and of course I'll help you to get better at it, but I know it takes a lot. That applies to most of the stuff you'll see tonight by the way. It's not because I know I can ask something from Number 9 that I'll expect that from everybody."

Turning back to Number 9, he ordered her to lift her skirt. He reached between her legs and ran little circles around her clit for a little while. He ordered her to open her mouth wide and immediately he put a toothpick between her lips so she had to keep them very wide apart. He pulled her panties down a little so that her pussy was revealed and then he continued his little circles for a little while. He then took a step back and started explaining what he had in mind for the evening.

Basically he wanted to try out the new machine he had constructed. He explained that there were three parts to the machine. The first part was a strong vibrator that could move up and down together with a dildo. Only when all the way up, the vibrator would touch the girls' clit and hence be effective. The dildo made sure that the vibrator would touch at the exact right spot. That it also filled the girl's pussy was a nice bonus.

The up and down movement was controlled by a mechanism on which the girl was standing. If she pushed her legs together, the vibrator would move up, but there were fairly strong springs holding her legs apart. It was clear that it would be tiring for her legs to keep the vibrator up.

The second part was another dildo, strategically placed in front of her mouth. The dildo had a button just above the base which turned the vibrator on for as long as the button was pressed. The catch of course was that the girl would have to deepthroat the dildo to turn on the vibrator. So in order to pleasure her clit, she would have to push hard with her legs while deepthroating the dildo.

"I'm curious how she'll do, I have a feeling that this device has potential to give me a great show. But of course I know that once she becomes tired, she might become less encouraged to put in the effort and the show might become less interesting."

He explained that that's where the third element comes into play. To avoid that the girl riding the device is making things too easy on herself, there are the nipple clamps. They're strong clamps in their own right, but as soon as she hasn't vibed herself for 10 seconds a motor will slowly start to pull the clamps with a rubber band. In 10 seconds, the rubber band will be stretched very far, pulling the strong clamps hard. If she still hasn't vibed herself during those 10 seconds, the rubber bands will start wildly vibrating on top of the strong pull. The vibrations last for 10 seconds, then the pull will release back in 10 seconds to leave her in peace for 10 seconds, after which the cycle starts again, over and over again until she vibes herself again.

"I think you can keep most of your excellent outfit. Just get rid of the panties and we can get you on the machine."

Number 9 stepped off the pedestal and followed the trainer to the contraption. She stopped next to it, turned away from him and with one smooth slow movement she bent at the hips and pulled her panties down. She waited a couple seconds while bent all the way down to allow him a good view of her bottom. Slowly standing straight again, she stepped out of her panties, bent again to pick them up and put them neatly aside. She returned to the contraption with her hands behind her back.

The trainer lifted her up and carefully positioned her on the machine, asking her to assist in properly inserting the dildo into her pussy. As it was pre-lubed, it went in very smoothly. After a few minor adjustments to the position of the dildo and the vibrator he moved on to positioning the deepthroat-dildo at the exact right height.

He ordered her to take the dildo as deep as she could, which was an impressive length, and positioned the button so that she could just reach it.

Nina stood up and came a bit closer to have a better look.

The trainer explained, "I'm just making sure that she can reach the button, but that it will be challenging for her, this thing is not meant to make it easy on her of course. "

Nina smiled. "It's amazing how she makes it look so easy to take all the way in her mouth! I tried it with some ex boyfriends, but I would never reach this far!"

"Yeah, again, don't you ever think that the level that Number 9 demonstrates here is in any way normal or the norm. She's very experienced in all of this, and has always been a natural talent to begin with," he answered.

"I can see that! Not sure I could ever do it like that!" Nina said with admiration in her eyes.

"As with everything, it's small steps and lots of training that makes one an expert. With sufficient motivation, I've seen girls take incredible steps!"

In the meantime, Number 9 had been deepthroating the dildo several times, pushing the button. The vibrator was already working but the trainer thought some minor adjustments were necessary.

"Well, I'm happy that at least this part seems to be working fairly well already. It'll need some finetuning to make sure that the intensity of the vibration is good so that she'll last long enough to be entertaining but still hard enough so that it's really challenging. Ideally I'd expect her to have at least a few strong orgasms by the time she's done on the machine. But anyway, that'll be a fine-tuning we'll have to do every time, as it'll be different for each girl and depending on her mood."

While he was speaking he strapped down her elbows and wrists behind her back so that she couldn't move much any more.

He removed the clamps from Number 9's nipples, handing them to Nina. He massaged Number 9's nipples for a while and then warned her that the new clamps would bite quite a bit. Once in place he told her to stop sucking for a while so that he could check if the pulling mechanism worked fine. And indeed, about 10 seconds later a motor started winding up the elastic bands attached to the clamps. But it was a good thing that he came prepared and has scissors ready because the motor didn't stop in time. He quickly cut the bands when the pull became too much for her nipples.

"That's no good." He shut off the machine altogether to check the problem. "I thought I set the pulling power to minimum to start, but surely I made a mistake there."

Soon enough he found the issue and fixed it, giving it a dry run without any elastic bands. The motor stopped quickly as it should and he put on new elastic bands, connecting the clamps again to the machine.

He turned the machine back on and asked Number 9 to give it another go. She pushed the button a couple times with her nose and stopped. All three were counting down from 10 in their head, waiting for the motor to start pulling. It did indeed, but nowhere near enough. He turned a knob a bit and they tried again. It was better already but still not hard enough. A little extra turn and this time he judged that it was hard enough to be effective as a motivation to start sucking again.

He watched closely for a while when Number 9 kept testing to see if it all worked as intended. A few more small adjustments and then he took a seat in front of the machine to enjoy the show.

Nina was walking around Number 9 all the time, observing her closely from all sides. She didn't want to show it, but she was getting quite aroused herself.

Once the trainer saw that the machine functioned properly, he added the vibration effect in the clamps when it had the elastic bands fully pulled out. Again he fiddled a bit with a knob to make the strength as he wanted it and Number 9 had to get herself punished on purpose to test the effect.

She wanted to go back to deepthroating immediately but the trainer stopped her and ordered her to endure 2 more pull/vibrate/release cycles to make sure he was happy with the strength. During the vibration on the second cycle, Number 9 cried out in pain.

The trainer asked her "Green?" and she immediately answered "Green!".

After the second cycle he allowed her to continue with the deepthroating so that she could avoid the pain in her nipples. While she got back to work, he explained to Nina that he used the "Green?" question as a safety, to make sure that she was indeed ok with what was happening. He explained that she was always free to answer "Orange" to indicate that it was at the limit and should not get tougher. or "Red" to immediately stop whatever is happening so that he can comfort her.

He sat down on the couch next to the contraption, watching her.

"Is it a bit like what you expected to see tonight?" he asked Nina when she passed near him on her circles around Number 9.

"I... I don't know Sir. I honestly had no idea what to expect really. I expected to see her obedient, I expected to see pain, I expected to see her tied up. I guess that's all here. But maybe I had expected, I don't know, things to be a bit more, what's the right word, brutal maybe? Maybe that you would be slapping her around, roughly fucking her immediately, something like that, I don't know."

"I see. For having no idea what to expect, that sounds like a very well articulated expectation and analysis to me. But maybe the bigger question then is, do you like this, shall we say 'gentleman-style'-approach better than the 'brute-style'-approach you expected?"

She was very quick to answer that. "Oh yes Sir! I think I like this style way more!"

"That's very nice to hear, Nina. May I ask what made you attracted to the BDSM-gear when you visited for the photoshoot? Any prior experience maybe?"

"No Sir, no experience at all. I mean, sure I had sex before, but not in a BDSM context. The most kinky thing I ever did was a blindfold while my ex touched me everywhere. I thought that was already quite something! I loved the first minute of that, when he was teasing me, until he just started fucking me for 2 more minutes and the fun was over."

"That sounds like a boy trying his best but just not really knowing what or how."

"Exactly, I don't blame him, but it did certainly feel like I wanted more of that sort of thing, so I started looking things up online. Obviously, that brought me to some serious porn very quickly. And it turned out the harsher BDSM scenes inexplicably got me the wettest."

She paused.

"I never dared to admit that to anyone!"

"It's ok Nina, not sure if you noticed, but I'm not the one to judge anyone," he said with a gentle smile.

Nina was still standing up, with the trainer comfortably on the couch.

"May I ask you a very personal question, Nina?"

"Of course Sir, now that I'm sharing anyway!" she answered with a disarming smile.

"Since the BDSM porn made you wet, how are things down there while looking at our mutual friend Number 9 here? Obviously, you don't have to answer that if you're not comfortable."

"I'll admit it. Watching her has the exact same effect on me."

"That's music to my ears, Nina. I must say, you sound amazing, not only do you look fantastic, that was already obvious when I saw your first picture, but you seem to really understand yourself, something which is very rare I think, especially since you're still very young. I can't assume anything else other than that you are a very intelligent woman."

Nina blushed.

"My intelligent beauty, shall we make things a little harder for Number 9, so that you get some harsher real-life porn here?" he asked Nina while standing up.

"I'd like that, Sir," she answered.

"Don't feel any obligation of course, but just in case you'd like a vibrator while we do so, they're on the tray on the right there, pick your favourite if you feel like it!"

He tweaked the knobs a bit to make the pull on the clamps harder and the vibration harder as well. He also increased the power needed to push the vibrator upwards and moved the button a little bit further up the dildo so she had to take it even deeper into her mouth.. All of a sudden, it became a lot harder for Number 9 to get the vibrator pushed towards her clit and to keep it there.

"Still green?" he asked Number 9.

"Mnmbllblmeen" she shouted with the dildo in her throat.

"I believe that was green, but just to make sure, close your eyes if you're green."

She immediately closed her eyes to indicate she was ok.

"Good girl. I'm surely enjoying the show, and I believe our friend Nina is feeling the same way."

While Number 9 struggled to keep working the machine, the trainer asked Nina if she had ever been spanked or whipped in some way. Nina said she hadn't but had been curious about it.

"Shall we try a few whips on our friend here?" he asked.

They went over to a tray where a bunch of different types of whips were laying neatly arranged next to each other and he asked Nina to pick three.

Nina investigated some whips a bit closer and then pointed to a large flogger, a riding crop and a cane.

"Excellent choices," he said with a smile.

He took the flogger and positioned himself next to Number 9.

"As she is clearly unable to count out the hits, can you do it for her? I'll give her 10 strokes, you just count them out clearly if you're ok with that."

"Sure, ok!"

He hit her 10 times pretty hard on her bottom and Nina counted the strokes for her.

"Do you think you could accept this amount of pain yourself?" he asked Nina.

"Depends how hard you hit me I think. But I guess I'll still be fine, yes."

"Would you mind handing me the riding crop?"

"That's this one, right?"

"Indeed."

She handed the riding crop to him and took the flogger.

"Same same for the riding crop, ready to count?"

Again 10 strong hits with Nina counting them aloud and Number 9 letting out muffled screams. Towards the end she stopped sucking for just too long due to the repeated hits with the crop that the nipple pulling mechanism started working. She immediately pushed the button with her nose again to make it stop.

"I think I'll have to adjust it for next time so that once it starts a pulling cycle that it does at least one full cycle. I think it'll be even more entertaining to watch."

He gave her the last few hits and asked Nina to exchange the whip for the cane. He explained to her that this was by far the meanest instrument she had picked.

"Number 9, I want you to pick a number: 1, 2 or 3? Just push the button the number of times you want to pick."

Number 9 pushed the deepthroat-button just once and then stopped for a few seconds.

"One it is. Good choice. The idea was that the number of strokes you'll get with this fine cane would be 30 divided by the number you picked. So I will now have the pleasure of hurting you 30 times."

Nina stared at him with big surprised eyes and a non-believing little smile.

"Here we go." After a few test-sweeps, he smacked her tender bottom with quite some power. The reaction from Number 9 was obvious, this hurt a lot more than the earlier hits. Nina watched closely and without being asked she counted the strokes aloud.

The muffled cries became louder and louder, but she kept sucking the dildo as if her life depended on it. When they were halfway, he stopped for a while and gently ran his hand over her bottom. The red stripes were clearly visible. He checked with her again that she was still fine to continue.

"We'll do the other half in a little while. I think I'll first enjoy the show a bit. Nina, feel free to join me on the couch here."

Nina and the trainer talked for a while, he inquired about her sexlife, her experiences and her fantasies. She felt safe with him and answered all his questions in detail. To test her fantasies further, he described a bunch of imaginary scenarios to which she tried to pick what interested her and what she disliked in the scenario. It turned out there was very little that she disliked and a lot that made her horny.

All the while, Number 9 was working hard to keep the machine from pulling her nipples. It turned out that after a few runs of the nipple pulling and shaking function, she was really really motivated to keep it from doing further runs. At one point, the trainer observed her a bit more closely, he had noticed she was getting closer to an orgasm. He stood up and grabbed a fistfull of hair.

"Don't cum just yet. You'll get your chance" he said while he pushed her head onto the dildo and the button. He made sure she vibed herself for a little longer than she had been doing on her own. He pulled her back and let go.

"If you withstand two cycles of the nipple pulling in a row I'll give you 5 attempts to have an orgasm. If you can't orgasm within the five first pushes of the button, you'll have to go through 2 more cycles before you can try again. So make sure you keep the button pressed as long as you can."

He sat back on the couch to watch her struggle. Nina was also watching her with big eyes, seeing her consciously waiting for the nipple torture to complete and then pushing herself onto the dildo to try to keep it this deep for as long as possible so that the vibrator would work enough so she could orgasm.

"One." he said in a very relaxed tone.

"Two. Three more attempts."

She got close in the fifth attempt, but didn't quite make it. "Back to the nipple pulling then, Number 9."

She let out a few screams when the machine started shaking her pulled nipples but she struggled through. Nina was watching her in awe, impressed by how she took the pain for the promise of a potential orgasm.

"Very good Number 9, five more attempts."

This time she was already a bit closer to her orgasm but it still took her four attempts to reach her orgasm. And that was quite some orgasm! She was only through the heaviest part when the nipple clamps started pulling again, causing her senses to go completely mad yet again and prolong the orgasm even more.

Nina was surprised that he didn't just give her a break, but that he left her on the machine to continue her ordeal.

"Shall we aim for another orgasm in about 10-15 minutes maybe?"

Nina answered immediately "Yes!"

"I was asking Number 9, but ok." he said with a big smile.

"You enjoyed the show then I assume?"

"It looked so intense! I don't know if I could handle the pain, but this is definitely the sort of thing I would love to try as well!"

"This might be a bit too much for a first attempt I think Nina, but there are surely options to take baby steps towards this intensity."

"Yeah, she just makes it look so easy! But I guess you're right, I'm still very far from her abilities!"

"The most important to me is that you seem very motivated to try, and that it certainly looks like you truly enjoy this."

"I do indeed, it's rare that I'm this horny without even touching myself! You should see how wet I am down there!"

They continued chatting about all the things that made her horny. He gave her a few dilemmas to answer, for example if she were to have lesbian sex if she would prefer to lick or be licked. She said that in her current state of wetness, she'd definitely opt for being licked.

"And would you want to make that reality? I'm just assuming now that you haven't done that just yet..."

"What are you suggesting?"

"Well, I happen to know that Number 9's oral capabilities are not only top-notch for men."

She looked at him in surprise. "Really?"

"I've ordered her to do it quite a few times on different girls, and trust me, she never disappoints. So, if you really want it yourself, I could ask her. No pressure at all, it's just an option if you choose to take it. She's still occupied for a little while anyway, so you have some time to think about it. And don't worry, I'll look the other way if you prefer, not because I don't want to see it, but just out of respect for you."

"I don't think I'd mind."

"Well, let's put it this way, I'll only look if you explicitly ask me to."

"Do I have to get naked then?"

"That's entirely up to you, I think taking off your panties would be comfortable, but other than that I guess you could just keep everything as it is."

He turned his attention back to Number 9 who was nearing her time for the second orgasm. "Well, sounds like you still have some work to do after this Number 9. In the meantime, are you ok if I record your performance for Tom to see the machine in action? One push is yes, two pushes is rather not."

Number 9 deepthroated the dildo for one push.

"Thank you Number 9."

The trainer took a bag from one of the carts and set up a few gopro cameras around her. He also gave one to Nina "Do you mind filming her for my friend? If you're interested, I'll explain who he is later on."

"Err, sure."

"Feel free to walk around, try to get some good closeups."

Just when Nina was taking a closeup of Number 9's pussy, the 15 minute timer went off.

"Time, Number 9. Let's start with the other half of your cane strokes. Nina, do you mind counting?"

"Sure."

Nina filmed how the cane painted red lines on her bottom while counting out the strokes. Towards the end of the series of strokes, Number 9 was a little bit late with pushing the button, so the nipple pulling started.

"Interesting. You're not making it easy on yourself Number 9. I like that."

He didn't wait for the nipple pulling cycle to finish to strike her again. Nina was so busy that she forgot to count it.

"If you're not counting it, it didn't happen Nina. So we're still at 9."

Immediately he hit her again.

"Ten!" Nina shouted immediately. "Sorry Number 9! Oh, I'm so sorry!"

"Yep, now she'll have more pain thanks to your mistake," the trainer rubbed it in.

"Oh, she should not have to suffer for my mistakes! That's just not fair!"

"What's fair anyway? Is it fair that I whip her in the first place? Were 30 strokes fair to begin with?"

Nina had to think about that for a bit. Then she answered, "Probably not, but I think she likes it in a way."

"Is it still unfair then? Or is it unfair that she gets to have all the fun and you can only watch?"

Nina didn't answer any more but started blushing. He gave Number 9 the remaining strokes, which Nina counted diligently while still filming the closeups.

"Are you ready to earn your first five attempts at an orgasm? Go for it. You know the drill. Let's show Tom on camera how the nipple contraption works. Entertain us."

But instead of immediately stopping to push the button so that the pulling mechanism would start working, she first pushed the button very long, activating the vibrator on her clit for as long as she could. She took a quick breath and did it again for a long time. When she couldn't hold it deep any longer, she let go of the dildo altogether and waited for the mechanism to pull and vibrate her nipples. It showed that the longer the clamps were on her nipples and the more often the pulling mechanism did its magic, the more she was truly suffering.

She screamed herself through two cycles and then immediately pushed herself back onto the dildo to get the vibrator working. She managed to keep the dildo in her throat for longer than she had done already tonight but unfortunately for her it wasn't long enough to reach an orgasm. She took a deep breath and tried again but she needed all of her five attempts to get there. The intensity of her orgasm was spectacular. Nina watched her with big eyes again, clearly getting quite horny herself.

"That was really beautiful, Number 9. Can you give us one more cycle of the nipple pulling and then I'll turn off the machine."

She obliged and screamed herself through another cycle.

"So beautiful! Thank you Number 9."

He turned off the machine and helped Number 9 off, guiding her to the couch where she could recuperate for a little while. The trainer went back to the machine to put some things in order, like quickly wiping the excessive drool from the dildo. Number 9 took a few deep breaths and then smiled at Nina, who was sitting next to her. That reassured Nina that she was all right.

Nina gets licked

"Ready for the next chapter, Number 9?"

"Can I have a couple more minutes please Sir?"

"Sure. Please kneel properly once you're ready."

"I will, Sir. Thank you Sir."

The trainer pulled out a sort of small but high bench which looked very sturdy. He asked Nina to come stand next to it and then adjusted the height a bit.

"Once she's ready I'll order her on her back on this bench. Her mouth should then be about the right height for you to benefit from... I won't give her any nipple clamps anymore as she has suffered significantly already. Instead I'll put rubber bands along the base of her breasts, that will make them very sensitive to the touch."

Nina listened intensely to his explanation.

"Sir?"

"Yes Nina?"

"You said I need to ask you if I want you to watch."

"True, I don't want to assume you want me to see you in any sexual situation. As I said, it's not because I don't want to see you have an orgasm after this scene of fairly significant sexual torture."

"I think I'm ok with it."

"That's good to hear, but that's not really asking me to watch you cum,"

"Please Sir, will you watch while Number 9 makes me cum while I think about her sexual torture."

"It would be my pleasure."

Number 9 took another deep breath in the background and slid out of the couch on the floor into a kneeling position with her hands behind her head, indicating she was ready.

"Number 9 is ready. I guess that means it's time to remove your panties."

Staring at her short dress, he smiled and waited.

Now it was time for Nina to take a deep breath before she pulled her panties from underneath her dress. She hesitated but then let out an "oh, fuck it" and pulled her dress over her head, revealing her entirely naked body to the appreciative eye of the trainer.

"Well well. Interesting. I saw your pictures already and of course your dress showed your figure nicely already, but wow. You obviously know this already, but your body is amazing!"

She blushed a bit and tried to hide her boobs with her hands.

"May I ask to put your hands on your head an slowly turn around for me?"

She looked at him and obliged. He was clearly enjoying the view.

"Absolutely beautiful Nina. You certainly have the body to become a very good lust object for men if I may be so forward."

"Thank you Sir," she answered, not really sure how to take that compliment.

"Shall we get our friend over here so she can lick your nicely bald pussy?"

"I think I'd like that Sir."

He went over to Number 9 and grabbed her by one nipple, pulling her on her feet and behind him towards the bench. He swiftly lifted her up and gently laid her down on her back on the bench.

"May I quickly grab the nipple clamps from my photoshoot? I'd like to wear them while she licks me, I think."

Nina had lowered her arms again while the trainer got Number 9.

"Nina, normally I'd ask if I had given any instructions to lower your hands, but I'll ignore that since you're a guest and not my slave girl tonight."

While he said that,. he had already grabbed the nipple clamps and he handed them to Nina.

"You might know it already, but make sure you put them far enough in your nipple, not just the tip."

"Like this Sir?"

"Very good. You can adjust the strength as required. Don't make them too easy but make sure you can keep them on for at least the time you intend to take to your orgasm."

Nine turned the screw a bit and pullen the chain between the clamps a bit. "I think it's ok like this Sir."

"Good, now, it might be interesting to put the chain between your nipple clamps in your mouth. If you want more pain, just tilt your head backwards. "

She put the chain in her mouth, lightly pulling the clamps already.

" Now, step forward until you touch her mouth. Number 9, tongue."

"I never had a girl touch me like that!"

"I thought so, but I know that you have a very good female mouth here to be your first."

Number 9 started licking her immediately and the effect on Nina was clear.

"Nina, before you have your orgasm, I want you to tell me."

He started cleaning up the predicament machine from earlier, putting it back into the large flight cases he had brought it in.

It wasn't long before Nina shouted, "I'm close!"

"Number 9, stop licking. Lets make sure Nina can enjoy the pleasure a bit longer. Will you pull your nipples a little bit further Nina?"

He walked around the girls, observing the two beauties in their intimate position. Nina's breath was getting back to normal and he asked her to count down from 30 for Number 9 to start licking again. Once she started, he asked her to count down from 60. 30 seconds pause, 60 seconds licking.

"Again, if you think you are about to cum, let me know."

It took a lot longer now, but after a few more full minutes of intense licking, Nina shouted again.

The trainer stood next to Nina and told Number 9 to keep going untill he told her to stop. Nina had a massive orgasm, while Number 9 kept licking her clit. Nina had trouble standing up and the trainer offered her a strong arm to support her. She was screaming in pleasure, while simultaneously pulling her nipple clamps pretty hard.

When the trainer thought she had had enough he ordered Number 9 to stop, and he gently guided Nina onto the floor. He helped Number 9 up and asked her to go take a quick shower.

He sat down on the floor close to Nina, who happily accepted a gentle hug. She recovered from her massive orgasm in his arms. She closed her eyes and couldn't stop smiling.

"It might be time to remove the nipple clamps Nina."

When she had them off, Number 9 entered the studio again in a bathrope and Nina handed her the clamps while gently massaging her nipples. The trainer happily watched her in his arms.

"Number 9, will you show her the shower? I'll wait for you girls here while I finish cleaning up. Let's have a drink together, ok?"

The girls took their clothes and went to freshen up. Number 9 came back with a cart with various drinks, alcoholic and soda's. She helped the trainer with the last few things and put the carts with BDSM stuff back in the other room.

Nina entered in her little black dress, carrying her panties. "I think these need a washing machine before I put them on again. I'll go home commando today."

"Oh, if you're uncomfortable you can grab some stuff from the clothes here. Doesn't matter. Up to you."

"Hehe, don't worry, I'm ok. But thanks for the offer."

Number 9 poured everybody a drink while the trainer said he'd do a debrief about the predicament machine with Number 9 some other time. He first asked Nina how the evening had been for her, if she got what she expected. She honestly answered that she had expected more of a brute as she said, not such a gentleman, but also that what she saw far exceeded her fantasies and that she loved every second of it.

She said that she was very uncertain last night about whether she should come, and that Number 9 had said she had felt the same before her first session, but that she never looked back since and never regretted taking the leap. She said she understood that now.

"That's very nice to hear, glad I could contribute to that experience. I must ask you then, would you like to explore more of this exciting world of BDSM?"

"I already made up my mind about that. There's no doubt about it. I need more of this!"

"In that case, I may have a proposal for you. Actually I might have a few."

"Oh?"

"Basically all proposals come down to the question whether or not you would like to become a number as well, just like our amazing friend here. If you accept the offer, I'd like to call you Number 37 from now on."

"37?" Nina shouted in surprise. "You have that many sexslaves?"

"There have been quite a few over the years, yes. Some have moved on of course and are not with me any more, but I'm very fortunate that most, like Number 9 here, are still regularly serving me.. We prefer to refer to the girls as lust objects or paintoys though, we're not really using the term sexslave, although it's not inaccurate either I guess."

"But to explain it better, I would like to invite you over to the venue where I usually do my BDSM sessions. Today we used Number 9's studio because it was a familiar place to you, but it's not the most convenient as I don't have all my stuff here."

Nina looked surprised. "Even more stuff?"

Number 9 smiled. "Oh, you haven't seen nothing yet."

"At least, I'd like to give you a tour of the place so you can understand what we're talking about. If you would like to experience a session yourself, we'll fix that, or if you prefer to watch another session before you decide, that's also an option. Or you walk away, that's always an option of course."

"Sir, I just had the most amazing orgasm while pulling strong nipple clamps after watching a scene of heavy erotic torture. I'm not really in doubt any more, I want more. Whatever you would order me to do right now, I would do."

"That's very nice to hear, and thanks for the vote of confidence. Oh, and don't misunderstand me, it's a very very tempting proposal, but I certainly don't want to rush you into anything and I believe you already experienced a but more than planned. Submitting to somebody should be entirely your conscious choice, not a result of a horny scene."

"I don't think that's the case. I've been thinking, well, dreaming, about it for a long time. I saw nipple clamps from up close for the first time a few days ago, that's true, but my dream is way older than that and I know now more than ever that I want to pursue that dream in reality."

"I understand Nina, but tonight was purely exploration, making sure we're a bit aligned. I don't think it's wise to rush things, no matter how much I'd like to do all sorts of things with your fantastic body. If you want to go fast, I could give you a tour of our facilities the day after tomorrow. I'm not sure if Number 9 can make it then, but you are welcome either way."

"Sunday is fine by me Sir, I have a shoot in the morning, but I'm free in the afternoon." Number 9 answered.

"And I will make it work, Sir!" Nina added quickly.

"Very well. Number 9, can you pick Nina up from here and come over together? I'll make sure I'm there from 2 pm onwards."

"Sure, works for me," Number 9 answered.

"What time should I be here then? Anything I should bring?"

"Let's say 1:45 pm at the latest. It's not far," Number 9 answered.

"And nothing in particular to bring apart from your own magnificent body. No dress-code or anything, you two can pick out an appropriate outfit there. Oh, right, I forgot, wear nice heels, like you do today, we don't have heels in all sizes."

"Of course Sir, no problem.."
