Oblivion: The slave-pilots
Written by @seismic_shifts
(Part 2)
Cian’s eyes followed every single movement of Yuma. The younger of the two white haired males was mesmerized by his appearance every single time he saw him. The two met at a slave-show for the first time – shortly after he was bought by his master Alvar. Yuma seemed to have been with his own master for quite a while, Cian concluded. With a soft blush, Cian greeted the completely naked boy. Even though he knew that Yuma was not very talkative and very well mannered – in contrast to Cian.
“H-Hello!” Cian said with a nervous voice. Yuma eyed him down for a short moment and then looked away with a bit of disgrace in his expression.
“Didn’t your master, Mr. Magnusson, order you to completely undress?” he asked, then looked at Cian before he continued. “A slave must obey to his master. How ignominious of you.” the boy with beautifully tanned skin said and brought his eyes down to the floor again, as he has been taught.
Cian’s face was turning deep-red. How could he forget that Yuma was a petty and highly obedient puppet. “Well, hello to you, too, then! Keep your advice to yourself.” he hissed, clearly embarrassed about the situation. “What do you even mean by ‘completely undress’. I’m naked. Just like you are!” the boy with shorter hair argued, before one of the lab-assistants turned around, looked at the two naked boys and then at Cian.
“I think he has a point though. Your piercings… they must go, too. Else you won’t be able to use the suiting-machine in a safe way.” the young male with brown hair said and pointed to Cian’s chest and then to his genitals.
But these words fell on partially deaf ears. All that Cian understood was ‘suiting-machine’.
“Woah, WOAH! What?! A suiting-machine? We’ll get to use a suiting-machine? And we’ll get some kind of bodysuit?! That’s AWESOME!” Cian blared, amazed by the fact he’d get to use a machine which Alvar had used on Cian a few times already. Cian loved wearing bodysuits. And he loved the feeling of using a machine which directly applied the bodysuit to his skin for a perfect fit.
“Can we use it like… right now? What kind of bodysuit will it produce?! Is it some kind of pilot-suit?! Is it going to be made of some super-awesome high-tech rubber?!” Cian continued to shoot questions at the lab-assistants without even thinking about the fact that Alvar ordered him to behave.
Yuma closed his eyes and positioned himself a few steps away from Cian. He even shook his head slightly but quickly refrained from showing too much emotion to make sure he wasn’t being an embarrassment for his master.
Alvar was in the middle of a conversation with Victus when Cian’s loud voice reached his ears. He quickly looked over to the lab-assistants and the two naked boys before he looked back at Victus.
“Seems like your little toy is misbehaving again. When will you learn to discipline him properly, Magnusson?” Victus asked with a mildly arrogant smirk on his lips.
Alvar was trying to end the conversation anyways and this was a very good opportunity to get the experiment started as soon as possible.
“When will you accept that there’s less perfect slaves than Yuma? Anyway – I will make sure Yuma’s going to get his special treatment during the night. I already included the functions of his slave-shell into the sleeping pods the boys will use.” the man with the curly, black hair said and took the first step away from Victus.
“You’re as bad-mannered as your little disobedient toy, you know that, Magnusson? Is this how you say goodbye to an old friend of yours?” Victus kept on teasing Alvar. But Alvar just waved at him and rushed over to Cian, Yuma and the two lab-assistants. The tall, blonde male shook his head, looked over to Yuma for a last time and then turned around to leave the facility. He’d return once the boys were undergoing the first experiments.
Meanwhile, Alvar approached Cian and grabbed his naked shoulders. His hands were resting on the light skin with a firm grip.
“Cian. Didn’t I order you to behave? You’ll get to know the experiment first hand. Just be a bit patient!” he said in a strict tone. But Cian was too excited to stay calm.
“B-but! I want to know if it’s going to be… like… one of the bodysuits the machines in your lab can produce! A-and I want to see the…” Cian stopped momentarily, looked past Alvar’s face and spotted the two slender, sleek and very large robots inside the hall behind the glass. “…MECHAS!”
Yuma watched the whole situation from a short distance. It apparently took Alvar quite some time to get Cian to focus on his task. Over and over again, the boy with the semi-short white hair kept staring at the robots instead of removing the piercings on his body. Cian wasn’t wearing as many piercings as Yuma – it was just his nipples and behind his scrotum as well as one single piercing on the base of his penis. After the metallic rings and bars were finally removed, Alvar began to explain a few basic things about the experiment. He instructed the boys and the lab-technicians about the initial steps and about the first experiment. Cian and Yuma carefully listened to the words of the dark-haired male who had to keep Cian from interrupting him. The experiment required the slave-boys to wear a special bodysuit, made of a polymer which contained rubber mixed with a metallic alloy and highly complex nano-machines which served as a sensor-array. The machines behind Cian and Yuma were, he continued to explain, designed to apply the ‘plugsuit’ both of them were required to wear for the duration of the experiment. The machines were cylindrical in shape and the size of a shower cubicle. Inside each of the cylinders, a human-shaped object – somewhat resembling a metallic suit of armor – was located. It was split in half, down until the knees where the metallic suit of armor extended in what looked like a set of boots. Tubes and wires were attached to the exterior of the ‘armor’. The front half was folded to the front so a person was able to place both feet into the ‘boots’ before it was folded up against the rear half to seal the person inside.
Finishing up the last steps of preparing both machines, the lab-assistants made sure both units were ready to operate. Meanwhile, Alvar instructed the two slave-boys to step into the machines and place their feet inside the boots.
“Yuma, one of my assistants will help you into the right machine while I’ll assist Cian into the left machine. The internal application-system has been custom-made for your bodies.” Alvar said with a friendly smile and looked at the tall boy.
“As you wish, sir.” he said and immediately walked over to the right cylinder before he carefully stepped into the cylinder. Cian stared at the naked body of Yuma, observed each single step until the 19-year-old male slid both feet into the lower part of the armor-like interior of the cylinder.
“Cian. Let’s go.” Alvar said and put one hand on the shoulder of the younger slave. He escorted him into the cylinder and looked at him for a moment without saying a single word. Then, he spoke up while looking into Cian’s eyes. “Seems like you enjoy watching him, huh?” he said and smiled in a cheeky way. The teenager immediately blushed while his eyes grew a bit wider. He realized he was obviously caught while staring at Yuma.
“N-no! I mean… y-yes! I… I really… uhm… you know he’s… beautiful! But he’s not fun! He’s so strict! Just like his master!” Cian complained while he quickly placed his feet inside the metallic boots. “O-oh! My toes just slid into something like… slots! It feels so similar to one of the machines you’ve already used on me!” he noticed and used the familiar sensation as a way to shift the topic away from his admiration of Yuma.
Alvar decided not to dig too much deeper into the topic of the dynamics between Cian and Yuma – for now at least. “Well… Yuma is a premium-lust-slave. They are well trained and even modified to suit their masters’ requirements. And Victus is highly interested in keeping Yuma in perfect shape and condition.” he explained before he pushed a button on a panel inside of the cylinder. “The individual slots for your toes should be familiar to you since this machine is based on one of my prototypes you’ve been helping me with. Now put your hands into the gloves and push your neck into the collar.”
Cian started to shake slightly since he knew how good it felt to be sealed in a bodysuit using this machine. He stood upright and brought his neck into the rear half of the metallic armor. Immediately after his light skin touched the collar, the front began fold upwards. Alvar watched the process of the complex mechanical parts slowly assembling around the young body of Cian and took care of a proper alignment. At first, the knees and thighs of Cian were engulfed by the armor, then his crotch, followed by his hips, his belly, his chest and his shoulders as well as his arms. The final part was his neck. The collar extended up until it held his lower jaw up to his ears in a tight grip. Small metallic clamps extended up towards his mouth on the front of his chin and just below his ears. A confirming nod from Alvar finalized the process. Cian was completely immobilized and looked like he was wearing a suit of armor that made him look like a cyborg. The armor had a separate metallic sheath for his testicles and his penis while the penis-sheath was definitely designed to house the erect member of the person inside the machine.
Yuma was in the same position like Cian at this point. His expression was neutral and he just followed each single instruction of the lab-assistant.
“Okay… Yuma… was your name, right?” the lab-assistant asked and looked at the restrained young male.
“That is correct, sir.” he answered with his beautiful voice. It was soft, a bit boyish, yet perfectly suitable for a male of his age.
“I will now instruct the machine to… uh… install a probe inside your body. It might make your feel aroused but… according to the way this machine works you’ll need to be in an aroused state while the suit is applied to your body.” The lab-assistant, probably in his mid-twenties and not too much older than Yuma, was clearly a bit uncomfortable with the fact that the machine forced the person inside the metallic armor to become erect.
“My sole purpose is to satisfy the needs of those I shall obey, sir.” Yuma answered. The lab-assistant looked at him in a slightly confused way until he realized that he was speaking to a perfectly conditioned and well-trained slave. A bit intrigued about how the restrained boy would react to the anal probe, he initiated the first phase of the suiting-process. With a soft hiss, a well lubricated probe was pushed in between the round butt cheeks if the long-haired slave. Yuma willingly accepted the large intruder without even changing his expression a single bit. He loved the feeling of being filled, especially with a large plug. The metallic probe extended deep into the rear opening of the boy and hit his prostate while sliding in. His member soon filled the smooth interior of the cylinder that was meant to cover his erect penis. Then, the eyes of the long-haired slave-boy grew slightly wider after the lab-assistant pushed yet another button. A long, metallic tube was slowly pushed into the urethra of Yuma. It was wide enough to stretch his sensitive urethra slightly. Once it reached the end of the length of his erect member, the air was sucked out of the metallic armor with an audible hiss. While Yuma was calm and composed, loud moans reached his ears from the neighboring machine.
“Haahh! Ahhh! Haahh! M-Master! It’s… hahh! Too wide! H-hahh!” Cian moaned, unable to move his body a single bit. “Hnnhhaahh! I-it feels… so good!” he added in between his lewd moans.
“Calm down, Cian. You should be used to the probes. Make sure you don’t reach orgasm just yet.” Alvar said as if it was the most normal thing in the world. But Cian was indeed trained on using urethral and anal probes. However, his body was also very sensitive and he was very lewd on top of that.
“Hhnnahh… M-Master! Please! M-make it vibrate! Make it vibrate!” the blushing teenager begged.
“Since you’re already fully erect, there is no need to add any form of stimulation. Now calm down a bit. I will leave the cylinder now. The application won’t take too long.
Yuma felt slightly ashamed for Cian’s loud and undisciplined moaning. He wasn’t allowed to moan, so he should remain quiet – even under high levels of arousal, he thought to himself. The lab-assistant already left the cylinder and in sync with the machine Cian was restrained inside, they both sealed shut. A dim, blue light illuminated the interior of both cylinders. Alvar checked the vital monitors of both slave-boys and gave the lab-assistants the instruction to begin with the application-process of the permanent suits which the boys were going to be sealed inside for several months. The master of Cian kept checking the live-feed from inside the cylinders to see if the boys were showing any signs of distress.
Inside the cylinders, a soft hum could be heard. Cian still moaned occasionally since he was highly aroused by the plug in his rear entrance and the tube inside his penis. Yuma was enduring the situation perfectly silent and without a noticeable change in his behavior. However, the premium-lust-slave secretly enjoyed being filled both from behind and inside his penis. It reminded him of the countless experiences he had with his beloved master. The hum in the cylinders shifted in frequency and the insides of both Cian and Yuma’s bodies were slowly pumped with a cleaning agent, meant to empty out their bodies of any contamination. Both intruders pumped a warm fluid into their bladder and into their rear entrance before it was sucked out again. This process was repeated several times to make sure the boys were completely clean on their insides.
Once again, it was Cian who moaned in deep pleasure. Both boys were used to this procedure – but Cian just wasn’t able to keep himself from moaning. Yuma just looked into the barely illuminated void of the cylinder and endured the process.
Followed by the internal cleaning of the slave-boys was the external cleaning and conditioning of their skin. The plugsuit which both boys were about the be sealed inside was designed for long-term application. This required the skin of both Yuma and Cian to be treated with a special fluid which contained small nanoparticles. These small particles made it possible for the rubbery high-tech material to adhere and fuse with the skin of the boys. Before their skin was treated, the interior of the metallic armor-like suit was rinsed with warm water and soap. This removed any trace of sweat and latex lubricant from their already permanently hairless skin. Both Cian and Yuma underwent several treatments to make their bodies permanently hairless except for their head and eyebrows. Finally, their bodies were coated with the fluid and the machines fell silent for a short period of time.
“It feels so good! Hnnahh… m-more!” Cian moaned. He didn’t care if anybody heard him. He just wanted more stimulation.
With the bodies of both slave-boys prepared for the final step, the machines came to life again. On the inside of the smooth, metallic surface of their armor-like suits including the tube in their erect members as well as the plug inside their rear entrance, microscopic nozzles began to eject the rubbery material. The machine allowed the plugsuit to be ‘printed’ on the inside of these metallic shells the boys were restrained in. The design and the colors as well as special features like sensitivity-enhancing functions and even sensors could be dynamically placed at any spot of their body. For Cian and Yuma, sensitivity enhancing areas were added over their erect members, their testicles as well as their nipples, their palms and their soles. It took less than a minute to form a layer of rubber on the inside of the metallic shell around the bodies of the slave-boys. Once it was properly solidified, the outer layer of the rubbery plugsuit was dislodged from the smooth inner surface of the metallic suit. Cian gasped and even Yuma let out a soft sigh once the incredibly tight rubber immediately hugged their bodies in a tight embrace from their necks down to their fingers and their individual toes. Even the insides of their urethra and their anus was coated in a very thin layer of rubber. The remaining fluid and any traces of remaining air was vacuumed out from between the rubber and the skin of both boys. After the suit was done adapting to the bodies of Cian and Yuma by tightening even further around their slim and well shaped appearance, the special apparatus which previously kept them immobilized opened itself up in the same way it closed around them after they stepped into the metallic boots. However, a part of the collar remained attached to their neck and the ‘clamps’ on the front of their chin and below their ears remained attached as well. Finally, the probes were removed from their now completely rubber-clad bodies. Again, it was Cian who let out a deep moan when the plug and the urethral sound slid out of the young body.
Not only did the machine produce an incredibly tight and highly revealing nanoparticle-based bodysuit, perfectly made to measure for the two slave boys, the machine also created a pair of thigh-high, semi high-heeled boots made of the same rubbery and shiny material in a separate compartment of the cylinder. These boots were perfectly matched to the dimensions of the boy’s legs and matched the design of the suits which the slave boys were now sealed inside.
It didn’t take long for the two cylinders to open up again, now with one rubber-clad slave in each cylinder. It was Cian who immediately jumped out of the cylinder after his feet were no longer restrained inside the boots of the machine.
“It’s a pilot suit! Oh my, it even has a separate sheath for my genitals! And all of my toes are individually wrapped! Look at the silver and purple color! It’s so tight, too! And… and these lines, numbers and letters all over the suit! Wait! Even my member has some kind of number written on it! Master! Look! Do I look like a pilot? Is it similar to the bodysuits you made for me in the past?! It feels really, really tight! And… and it’s tingling! I’m still erect, too!” Cian jumped around and admired his body in the tight rubber pilot suit. He even pointed out that he walked around with an erect penis – it wasn’t bothering him at all.
“H-hahh! Oh… oh my… hnnhhh… i-it feels so good!” the young slave-boy said and now had his hand around his shiny, encased shaft. Alvar didn’t waste any time and immediately approached his slave and grabbed his wrist.
“Cian! Don’t touch yourself unless you’ve been ordered to do so! What do you think you’re doing?! You can’t just start to touch yourself! The suit hasn’t been calibrated yet!” the dark-haired male said and looked at Cian with a bit of anger is his eyes.
Realizing how he let himself get carried away, the boy with the short, white hair bowed his head a bit, looked to the ground and apologized to his master.
Meanwhile, Yuma slowly stepped out of the cylinder after he was told to do so by one of the lab technicians. He felt a bit ashamed about the fact that he still had a well-developed erection. He wasn’t explicitly told to become aroused after all. But the graceful young male realized that it was an immediate effect of being sealed into this full-body suit. He looked down on himself for a second, before he directed his full attention back towards the lab-technician. Being fully wrapped in a tight layer of rubber made Yuma feel better than being completely naked. Even though his suit revealed the form of his body in all detail. Yuma’s suit looked a bit different than the suit of Cian. While the suit of the younger slave had a darker silver color, Yuma’s suit was a brighter silver with purple highlights, matching his eyes perfectly. Cian had purple highlights on his suit, too – but also a bit darker to match the color of his eyes. After the lab-assistant handed the long boots over to Yuma, he obediently placed his feet and legs into them before they vacuum-sealed tightly against the rubber on his skin.
Aside from the skintight rubber and the boots, the shoulders and the area between the shoulder blades was a bit thicker on both cockpit-interface suits. This made the boys appear like a pair of very lewd space-fighter pilots. Much to the joy of Cian, who felt like a real mecha-pilot at this point. Once Cian was in the thigh-high boots, too, Alvar began to explain what was about to happen to them over the next few months.
“Yuma, are you feeling alright?” Alvar asked, since Yuma was very quiet. Especially in comparison to Cian who didn’t stop bragging about how much he enjoyed the suit.
“Yes, sir. Although, allow me to mention that I am currently not following my orders since I was not permitted to become erect, sir.” Yuma’s voice was calm and sounded very soft. However, his expression revealed clear discomfort and he didn’t like the fact that he was not able to keep himself under control.
“Oh… this part…” Alvar began and looked at the shiny penis of Yuma, still erect and at full mast. “Well… I should have explained this a bit earlier. Applying these suits requires the wearer to be erect and therefore… the machine will inject a tiny amount of arousal-enhancing fluid into your body to keep you erect for some time. The suit will adapt to your genitals, even once you calm down again. So don’t worry about this. You’re free to become erect, Yuma.”
Cian kept scanning Yuma’s appearance over and over again. He wasn’t able to keep himself from staring at his perfect body, now that he was inside this shiny rubber suit. This, in turn, fired up Cian’s arousal even further. He bit his lips and nervously moved his weight from one leg to the other. Yuma, in the meantime, stood perfectly straight and still.
“Now…” Alvar began “...these suits are part of the new cockpit system you’ll be testing for the upcoming few months. As you’ve already noticed… the suits have been applied in a way which… makes them permanent. At least for the time being. Once the experimental phase is over, we can remove the suits again. But for now, you will remain locked inside the suits. The functions of your body will not be restricted in any way. But… I need to make very clear – especially for Cian – that you are not allowed to touch yourself or, even worse, to reach orgasm without authorization!”
Alvar went on and explained the boys that the boots were removable, however they were supposed to keep them on their feet all the time except inside the cockpit and inside their sleeping-pods. A few further notes about the way they’d utilize their new sleeping-pods were shared, then both boys were introduced to their mechas.
It took around ten minutes and the first punishment of the day before Cian was able to calm down after seeing the tall and powerful-looking humanoid robots for the first time. Even though Cian begged for mercy, Alvar temporarily forced a purple ball-gag into the mouth of Cian to silence him. Yuma, meanwhile, felt highly embarrassed about the way Cian was behaving. He tried not to speak up about the nasty and disrespectful behavior and succeeded. However, the usually well-composed and resilient premium-slave had a slightly annoyed expression on his face.
“You won’t be able to use the new interface-system in this cockpit right away. And it is not our main objective to turn you into mecha-pilots. You simply serve as test-subjects and you will, in the future, perform realistic simulations to test the different effects of the interface system in response to your state. What I mean by this is simple.” the man with the dark hair and the bright eyes explained.
“This interface-system is designed to work with the highest efficiency if the test-subject is aroused and as close to an orgasm as possible. This is why I selected you, Yuma and you, Cian, to be the test subjects. Only well-trained pilots will be able to use this interface-system. But I expect the best results ever achieved for a sync-ratio between the mecha and a pilot.”
Alvar walked over to Cian and looked at the gagged boy in full rubber, still erect in his high-tech pilot suit.
“Will you behave once I take this thing out of your lewd mouth again?” he asked with a smirk on his lips.
Cian, who tried to manipulate his master into believing him by using his puppy-eyes didn’t succeed at first. But then, Alvar carefully undid the straps around the neck and the back of the head and removed the ball-gag from the teenager’s mouth.
“Y-yes, master!” Cian replied with a blush of embarrassment on his face.
“Yuma, one of my lab-assistants will guide you into the cockpit and help you with properly connecting to the interface-system. Cian, you’ll come with me.”
“Yes, sir Magnusson.” Yuma replied and turned towards the lab-technician. Both of them disappeared into a nearby elevator which brought them to a platform behind the chest-area of the mecha.
Just like Cian, Yuma was still erect. The lab-assistant observed the premium-slave, even blushed a bit himself since the nineteen-year-old really was beautiful in every aspect. Both of them soon arrived at a small table with a shelf next to it.
“Before I can guide you into the cockpit… uhm… you… you need to put this on. It’s… a-also made to measure for you and… as you can see here… there is a small hole for your hair. Could you… please tie your hair into a high ponytail?” the lab-assistant asked. He was a bit nervous around Yuma – even though there was no real reason for that. But the graceful and elegant figure and his breathtaking beauty were hard to ignore. Even for the lab-assistant.
Yuma was handed an object which looked like a piece of the rubbery fabric his suit was made of. It was completely silver and matched the color of the silver areas of his pilot-suit exactly. Once his slender finger unfolded it, the orb-shaped appearance revealed a full hood which engulfed the entire head in tight rubber. The premium-lust-slave was used to wear this kind of garment and had no issues with wearing this silver hood either. Without hesitating just a single second, Yuma prepared his ponytail with a small hair-tie provided by the lab-assistant. With well-practiced precision, he brought the flexible item up to his chin and quickly stretched it over his face until he carefully worked the hood over the back of his head and down to his neck. The lab-assistant grabbed his long hair through the small hole on the back of Yuma’s head and in no time, Yuma looked like an anonymous rubber doll. His beautiful face was now completely hidden and the only trace left of his appearance was the long, white and purple hair on the back of his head. The rubber-hood had two small tubes attached on the inside which went into the nostrils and a very small hole directly over the mouth. To Yuma’s surprise, he was able to see through the material – even though it appeared opaque from the outside.
Meanwhile, Cian was fully sealed inside the hood, too – but without a single trace of his hair visible. Cian appeared even more like a rubber doll or a rubber-drone.
Both boys were more or less simultaneously introduced to their cockpits. They took of their long rubber boots and entered the mecha. The interior was a small chamber with metallic-silver walls and well illuminated. In the middle of the capsule was a complex mechanism. The legs of the pilot were inserted into holes inside the floor. Both feet and the lower legs until the middle of the thighs were disappeared inside the floor of the cockpit into sleek tube. However, once inserted, the feet were located inside a small space beneath the leg-restraints where the pilot was able to freely move around the feet while the legs were in the tight grip of the tube-like restraints. The arms were housed inside similar restraints while both hands also rested inside the same small space where they were able to move around into all directions without being restricted in their movements. The rest of the pilot’s body was restrained by a complex mechanism made out of metallic and very strong stripes attached to flexible arms in order to adapt to the pilot’s height. Once fully secured, neither Cian nor Yuma were able to move anything else but their head, hands and feet. Finally, the already rubber-clad heads of both boys were equipped with a helmet, previously located above their now fully restrained bodies. The helmets had a silver-purple design and also matched the suits of the two slave-pilots. Once the helmets vacuum-sealed against their collar, Cian and Yuma were left in complete darkness.
“Now that you’re fully restrained, the mecha will do the rest. I won’t be able to stay inside the mecha once the connection to the pilot is being initiated. But both the lab-assistants and myself can talk to you. Okay?” Alvar asked the figure, tightly restrained in the cockpit and deprived of any distinct human features except the rubber-clad, shiny erect penis and testicles.
Cian just nodded since it was a bit hard to speak through the tight layer of rubber over his mouth.
Once both slave-pilots were sealed inside their mechas, the lab-assistant and Alvar rushed towards the elevator and soon met the second lab-technician behind a large console with large screens directly behind the windows inside the lab.
While Yuma was able to remain calm in complete darkness, Cian began to moan and flexed his rubber clad toes in arousal. He pictured himself and even Yuma inside the cockpit. Restrained. Exposed. Lewd. Ready to be used as a human toy by the mecha.
Suddenly, both boys found themselves looking at their own body from a high-resolution camera positioned within the cockpit. The helmets and the sensors inside the hood which connected directly to their brain were activated by Alvar.
“Cian, Yuma, can you hear me?” he asked, closely watching their vital details on a separate monitor.
“Mhm.” both boys responded, slightly muffled.
“I want you to focus on utilizing the mind-to-speech system of your helmets. Just put a strong focus on what you want to say and it will be translated into speech.” Alvar explained.
It took both boys a short while to properly adapt to the new way of communicating verbally. But eventually they both managed to exchange information with Alvar and the lab-assistants.
“We will now let the mechas connect to your body through the interface-system. You will feel a bit strange at first – but this is completely normal. The suits and the interface-system will immediately begin with a calibration-process. This will take a while and it will probably make you feel very, very aroused. I want you to enjoy this, okay?” Alvar explained with a smirk on his lips. He knew that the boys would be edged for more than two hours.
A simple “Yes.” was read from Cian’s mind while a polite and well-mannered “Yes, sir Magnusson. As you wish.” arrived out of Yuma’s cockpit.
Alvar gave the lab-technicians the signal to start with the first experiment. The two young assistants activated the mecha’s cockpits and the interface system.
Inside the cockpits, the two restrained and rubber-clad slave boys were able to watch how their bodies were equipped with wires, tubes and lewd equipment at the same time. The first item which claimed a part of their vulnerable bodies was a transparent cylinder with a sophisticated mechanism inside. It was mounted into a silver, segmented tube and slithered towards the boys’ erect penis before it latched into their crotch with a slurping and hissing sound. Once inside the cylinder, the vacuum sucked their erect members tightly into a soft, lubricated and tight interior. Lined with soft silicone and several rings which were able to move individually, it was the perfect tool to stimulate their rubber-sheathed members. Once the cylinder was properly positioned over the restrained boys’ hard members, a long and ribbed silver tube was pushed down into their urethra until it reached their prostate. Parallel to the cylinder latching onto their penis, the helmet forced a large phallic gag into the mouths of Cian and Yuma.
Alvar watched the camera-feed and the monitor with live-data from Cian’s and Yuma’s bodies as well as their arousal-level and basic readings about their brain-activity. Cian moaned into the gag within his mouth and was way more invested in the scenario than Yuma. His breathing-frequency was only slightly increased and his perfectly silent behavior resembled in him not even making a single sound while his penis was engulfed by the machine and finally equipped with the long tube that went into his rubber coated urethra.
The next device that was connected to the boys were nipple-suction cups with internal mechanical stimulators. The already erect nipples of both boys were perfectly visible beneath the thin and tight rubber of their pilot suits. The transparent cylinders automatically centered over the sensitive nubs of both boys and applied a strong suction until the nipples were sucked into the tube-shaped cylinders. Once perfectly aligned, small silicone-nubs began to stimulate the nipples of Cian and Yuma. However, the boys had no time to focus on the new stimulation device. Two wires were attached to their shiny testicles and immediately began to send tiny electric shocks into their scrotum. To add up to the nipple suction cups and the milking cylinder, a large plug attached to a rod was pushed into the boy’s rear openings. The plug inflated and also began to vibrate inside their bodies. Meanwhile, the underside of their toes and their fingers were wired up and stimulated though electric impulses, too.
Cian was now constantly moaning and his thought-to-speech module translated his lewd thoughts into single words. It was obvious that the fully sealed rubber-slave inside the cockpit was begging to release. However, unknown to Cian and Yuma – the interface-system was designed to refuse both boys to reach orgasm as long as they were connected to the interface-system. At least until the orgasm-inhibition was turned off manually.
“Subject secured and connected to interface system. Subject will now undergo calibration.” a text inside Yuma’s and Cian’s visor read.
For the upcoming two hours, Cian and Yuma were simultaneously undergoing a very lewd and very exhausting row of experiments and tests. Both slave-boys were constantly brought to the edge of an orgasm by the lewd devices attached to their bodies, with additional stimulation applied with the help of the bodysuit they were sealed inside. The boys were stimulated until they reached an arousal-level of at least 90% in the first 30 minutes. This happened once per minute. While Cian was constantly moaning and screaming, Yuma endured the edging-sessions in perfect silence. Only his heart-rate and his breathing-frequency increased a bit. His perfect training was quickly revealed since Alvar and the lab assistants were able to compare the brain-activity between the two slaves. While Cian enjoyed the stimulation and showed it off by moaning and screaming, Yuma enjoyed the process to the same extent but managed to keep his reaction to a minimum. This also resulted from the slight brainwashing which Yuma underwent each night.
The remaining 90 minutes were filled with the same edging-experiments and tests. However, the system began to push the boys further and further towards sensory overload. Sometimes, the interface-system stimulated just their feet or their nipples and then activated the remaining devices once they were close to an arousal-level of 98%. This resulted in Yuma spiking up close to 100% - but the orgasm-inhibition function made sure that even if one of the two boys reached 100%, they would not be able to reach orgasm.
As more time passed, Yuma seemed to become more and more exhausted. The first signs of exhaustion showed after 106 minutes of constant edging. Yuma began to curl his toes once he passed an arousal level of 97%. Unusual for the usually well-mannered boy. Yuma was clearly upset about himself loosing control over his body. This only resulted in his resilience getting lower and lower. Soon, Yuma was breathing heavily. His beautiful voice could be heard, muffled by the gag in his mouth, as he moaned into the helmet.
“It seems like Yuma is becoming slightly unstable.” one of the lab-assistants noticed.
“Continue – only interrupt the calibration if it is really necessary.” Alvar said and watched the live-feed of Yuma.
In the final stages of the experiment, Yuma began to moan in the same intensity as Cian. Both boys were highly aroused and managed to reach 98,5% of average peak-arousal for Cian and 99,6% if average peak arousal for Yuma. Both results were higher than expected and revealed how perfectly suitable the boys were as test-subjects for the new interface-system.
After the last second of the 120 minutes passed, the bodysuits of the two slaves had pumped away quite large amounts of sweat. The phallic gags in the mouth of the boys supplied them with water, infused with necessary nutrients to keep them well hydrated. However, neither Cian nor Yuma were allowed to leave the cockpit yet.
“How are you feeling, boys?” Alvar asked and looked at the screen which translated their thoughts.
While Cian’s screen was flooded with words like “orgasm” and “cum” as well as “please”, somewhere in the middle of the countless words “I am okay!” could be found. Yuma, on the other hand, seemed to be busy thinking about how disgraceful it was to moan without permission. However, he, too, managed to properly inform Alvar that he was doing okay. Both Cian and Yuma were, however, quite exhausted.
“Before you can leave the cockpit, we need to initiate the proper installation of the external orgasm inhibition device.” Alvar explained and then gave the instruction to install the sinister device on the boy’s bodies.
Inside both cockpits, the cylindrical-shaped milking device was removed from their still erect penises. The wires attached to their testicles were also removed. Then, a mechanical arm brought a shiny, silver device over to the boys’ crotches. It matched the color of their suit and appeared like a large pouch with a narrow opening that was made of some sort of metal. The opening automatically expanded once the device was close to the genitals of the boys. In one swift movement, their semi-erect members and their testicles disappeared inside the rubbery, round pouch. Once the pouch was pressed against the base of their genitals, the metallic ring shrunk down until it tightly grabbed their testicles. Even though the pouch was flexible, it felt very, very tight. Over the time, as Cian and Yuma slowly recovered from the effects of the long-term edging, their members became more and more flaccid. The pouch began to shrink around their penis and testicles further and further – until the pressure was so intense that their still semi-erect penises were tightly pushed down and curved around their testicles. Then, the previously flexible pouch became rock hard and solid. Finally, a smaller mechanical arm brought over a curved, but thick tube and inserted it into a small hole inside the pouch. The tube was inserted into the urethra of both boys and sealed against the pouch. The chastity device looked like an extension of their pilot-suits and revealed their locked up genitals at the same time.
Both boys were soon walking out of the mecha on shaky knees, exhausted from the experiment they were forced to endure. However, both Cian and Yuma enjoyed being helplessly restrained in these high-tech cockpits while being permanently edged. The boys quickly removed the rubber-hood over their head and then walked up to their boots, placed them onto their feet and legs and walked over to Alvar, who was waiting for them on the bridge behind the two mechas.
Cian immediately complained about the chastity device.
“You didn’t tell us that we were going to be locked up! These feel way too tight! And.. and we were not even allowed to reach orgasm!” he said, while Yuma – still blushing at this point – looked to the side and away from Cian.
Alvar simply grinned and inspected both boys’ crotches.
“Well – bad luck for you then, Cian. You won’t be allowed to reach orgasm until the first row of experiments and tests is over. And this will take at least three weeks.” he explained, much to the dislike of Cian.
“B-but! But then at least let me take it off! I won’t reach orgasm, I promise!” Cian tried to bargain his way out of the very tight object around his genitals. At this point, Yuma turned around and faced Cian with a neutral, but clearly upset expression.
“How can you speak up like this, you selfish boy? As a slave, you should be grateful to be able to wear a chastity device.” he said, turned towards Alvar and apologized for speaking up.
“Keep that to yourself, you perfectly-trained pet!” Cian hissed with a blush on his cheeks since his “idol” called him out.
“Before you’re ending up in a fight, I think it’s time for me to show your sleeping pods to you. Since this is a long-term experiment, you will live inside this lab for the time being.” Alvar explained and lead the boys over to the lab-area where the highly developed and futuristic pods were located.
Cian and Yuma remained in the lab for two full months. The effects of the sleeping-pods were beneficial for their usage as test-pilots for the mechas. However, the brainwashing also resulted in Cian and Yuma becoming more and more addicted to the process of being edged over and over again. After exactly four weeks, the first phase of synchronization-experiments was over. In the next phase, Cian and Yuma were trained on utilizing their sensitive rubber-clad hands and feet to control the mecha. What went unnoticed by Alvar, the lab-assistants and both Cian and Yuma were strange anomalies inside the mechas. The control-system was, unknown to everybody, constantly overriding the safety-limits of the orgasm inhibition function. This allowed the mechas to directly interface with the pleasure-centers of Cian and Yuma and resulted in a full stop of the experiments after both test-subjects were already well-trained. A big strike both for Alvar and the two slave-boys who got used to being the test-subjects for the new cockpit-interface.
One month later.
“Cian? I want you to come down into the lab. I have a small surprise for you.” Alvar announced using the intercom-system in the large mansion.
With a big smile on his face – Cian loved it when Alvar commanded him to join him in the lab as it usually meant that he was going to be used as a test-subject again.
Cian was barely clothed since he was at home. He was wearing a very tight hot-pants made of black rubber and a pair of low, black rubber-socks. Once the white-haired teenager walked through the automatic door of the large lab in the basement, his purple eyes widened. He was looking straight ahead at a very familiar figure in a very familiar outfit. Another person stood next to the young male in the pilot suit while Alvar was holding a shiny silver and purple outfit in his hands.
“M-Master! What are Yuma and his master doing here?! W-Wait! Don’t tell me…” Cian said and sprinted over to the group of three.
“You’re letting him run around like that?” Victus asked after he saw Cian. “Shouldn’t a slave always be restrained and well clothed?” he added before he was interrupted by the young teenager. He clicked his tongue and turned to Yuma. “At least you are well-mannered and perfectly trained, my dear Yuma.”
Alvar simply ignored Victus and approached Cian who was staring at Yuma’s perfect body.
“Well, as you can see, one of our visitors is already back in his pilot-suit. The issues with the interface system have been resolved. But before we go back to the lab… I agreed with Victus and you and Yuma will undergo a special session inside the pilot suits.”
Alvar handed the pilot-suit to Cian. “Why don’t you get dressed? You know how the suiting-machine works, don’t you?”
Cian didn’t need to hear the order a second time. He rushed off and quickly prepared the suit and the machine. Once the teenager was – once again – sealed in his pilot suit, he was ready for a very special training-session.
Later this evening, Alvar and Victus enjoyed a few drinks while listening to the moans of their brave slave boys as they were forced to reach orgasm after orgasm.
