Mass Effect: One Krogan's Cure

Commissioned by Yolk

The Genophage had devastated the Krogan race for centuries, and no one seemed to care. Oh sure, it was in the back of the mind of every Krogan in the galaxy, but it sure didn't seem any of them were willing to do a damn thing to try and fix it. All they were concerned about was fighting and killing, to prove themselves superior. A few would go out there and spend ridiculous sums of money to replace their quads which, of course, was an utterly pointless act. None of the other species were helping and that was with good reason. Even if they were altruistic enough to spend billions of credits on developing a cure for an alien and generally hostile species, the council would never allow it. After all, they were the ones who created the disease. The only solution left was from the private sector, but the kind of funds needed for that would be astronomical. It would weaken any of the major Krogan clans if they tried to fund it, inviting the other clans to come in and wipe them out rather than risk their enemy get any kind of advantage over them. That was exactly the reason the species would never be able to come together and pool their resources.

It certainly appeared to those who were relying on the Genophage to keep the Krogan in check that nothing would cure it. However, it never occurred to them that a single individual might be able to do what whole clans couldn't. For a single Krogan to be able to do that would require an unprecedented amount of forethought, planning, and patience. None of those were traits normally associated with the belligerent species, especially the last one. Never the less, that is exactly what happened. Yolk was an unusual Krogan, born shortly before the Genophage was released. He was a decent, though unexceptional fighter, however he was good enough to pass the only bar that mattered, surviving. More important than his combat prowess was his mind. It was unusually sharp, able to read people and patterns that most couldn't even notice. Once he left Tuchanka he was able to put that ability to great use in economics, an area no one would ever expect a Krogan to excel. From the shadows he was slowly able to build up a considerable amount of wealth and power through a series of investments as well as creating a few companies to exploit areas of the market that were under served. After a few centuries those handful of companies had ballooned to dozens, and among all of those were a few that dealt with pharmaceuticals and bio-engineering. Once he had those in place, it wasn't that difficult to find employees that would be willing to work on a cure for the Genophage.

Of course, having money and those with the know how to create a cure was only part of the problem. The other part was time and somewhere to work safely away from prying eyes. The only place to avoid intervention by the council or their specters was out in the Terminus systems. That was hardly the safest place to live, but with ample security and very high pay checks, he was able to convince several talented scientists to work for him in near absolute seclusion. Several years had passed since this secret facility had been created, and everything had gone according to Yolks plan. It was finally time to test their cure, and he was determined to be the first subject.

Yolk walked into the sterile white room. He was completely naked, showing off his muscular, tall body, his glutes and legs being particularly strong and well toned. Despite not seeing real combat for years, he still was sure to keep himself in shape. His most unique attribute was his hide's unusual tone. Most had a tan or dark brown, but his was a strange almost iridescent blue. Between his legs were four sandy blond tinted softball sized testicles and a large limp bright red soda bottle sized cock. He didn't think anything of his nudity as he walked towards the test apparatus, and neither did scientists. After all, it was completely logical for the procedure and they had seen him like this many times because of the numerous tests they ran on him. "Lets see if we can make history, shall we?" Yolk said as he leaned against the reclined skeletal metal slab. The scientists agreed, and with one on each side, they began to hook him up to the various machines that would be used. Thick metal bracelets were clasped to his wrists and ankles, holding him in place with his legs spread. A cage like device was pushed around his quads while a tube like structure encompassed his limp dick. Finally several thick tubes were attached to his chest and spine.

"Sir, I have to reiterate that I believe this is not a wise decision," Zoban, the lead Salarian scientist said as he affixed a thick tube to the cage like device around the Krogan's testicles. "While the test don't show any significant signs of danger for the procedure, there are still certain side effects that we haven't been able to account for. Jumping straight to Krogan test subjects, especially ones vital to the projects is potentially dangerous."

The Salarian was a pretty average height and build for his species, though he might have been ever so slightly heavier than most. This was possibly due to the lavish living that he was able to enjoy at Yolk's expense, though it was equally likely just to be due to his genetics. The majority of his skin was a subdued purple, while other areas, such as his mouth and nose region were an extremely light blue that almost bordered on becoming white. The darker pigment became increasingly smaller splotches as it gave way to the lighter tone, creating a pleasing transition.

Yolk rolled his eyes hearing the same argument for what seemed like the tenth time today. "I told you before, I'm willing to risk it. Besides, it's not as if there are many other male Krogan's volunteering to be tested on by strangers, and even if there was, do you really think they'd pass the back ground security checks? Most are either loyal to their clan, or mercenaries out for themselves. Now just drop it and finish hooking me up."

"Fine, but don't start yelling at me if something unexpected happens." Zoban replied dryly as he walked away, letting his assistant finish hooking up the Krogan. It took another five minutes, but finally all the restraints, tubes, electrodes, and sensors were in place.

Daekon, the slightly shorter and younger Salarian still in the room walked away from Yolk and over to the intercom. He was skinnier than his superior, with a red skin tone that faded out to a lighter salmon color, though his transition was more like freckling rather than splotchy. In a way, that almost made him look much younger, even if the age different between the two men was only a little more than a year. The most unique thing about him was his voice, which even for a Salarian was high pitched. "Everything is set up here, we're ready to begin."

Zoban, now in the control room, let out a sigh while he quickly typed a few details into his terminal then started the procedure. The sound of buzzing fans and the mechanical whirling of gears filled the lab as the equipment came to life. Yolk heard the sound of rushing liquid and saw the tubes in his field of view fill with bright colors as the drugs were brought towards his body. He didn't have time to identify which was which before dozens of needles jutted out of his restraints. He grunted in pain, gritting his teeth tightly as his flesh was penetrated. The ones in this back, legs and arms wasn't bad at all, but the ones going into his dick and balls were considerably worse. It was necessary though, he needed to be able to communicate with the Salarian's in case anything went wrong. Still, he'd felt much worse pain in combat, so this wasn't that bad. Then the liquids began to be injected into him. That was so much worse, some of the drugs were ice cold while others were near boiling hot. He grunted out in pain, tensing his muscles reflexively which only made it worse as it just meant more resistance for the liquid had to overcome as it spread his tissue.

"You're doing well sir, you're over half way done." Daekon said, observing his bosses discomfort. "The drug should begin effecting your body after that and the pain should reduce." Yolk snarled at the Salarian with his calm, detached demeanor but bit back saying something insulting. The Salarian was right though, after half a minute the pain started to subside and Yolk began to relax slightly. That's when the physical changes began to occur. Over the next five minutes the Krogan's body was altered, both on a genetic and cellular level. Most of these changes would require the use of high precision medical equipment tailored to detect changes in the DNA and other microscopic alterations. However there were other more obvious changes that could be measured with just external observations. "The subject's body is exhibiting slightly greater than predicted growth. I'd estimate muscle mass has increased by 10-15%, and height has increased by at least 5%." Daekon said circling around Yolk and looking more closely at his body. When he neared the man's crotch, his brow furrowed slightly. "Testicles and penis both appear to have increased significantly, I'd say at least 30% and are now pushing up against the medical restraints. A slight increase was expected, but no were near this degree. Is this the kind of side effect you were worried about Zoban?"

"Exactly, this sort of thing could have been worked out if we had more time." Zoban replied over the intercom while shaking his head side to side."

Yolk gave a small laugh. "I don't know, this doesn't seem like that bad of a side effect. I mean what guy would say no to a little improvement to his dick?"

"That isn't a little improvement, it's a massive change. Besides, it's not just your size changing, it's what other effect that change will have on the rest of your body. It could throw off everything else. We'll need to run some additional tests now."

"What sort of tests?" The blue Krogan asked.

Daekon walked over to a cabinet and pulled out another metallic cylinder that was not unlike the one already on his penis, except this one was enclosed on the end with an aperture that the tube could be connected too. Additionally it was more robust looking, with segmentation that appeared to allow it to move up and down while the interior appeared to be covered in some sort of soft flesh like synthetic material. "Really, is that a penis pump?" Yolk asked dryly as the younger Salarian approached and began to undo the device currently encompassing his dick.

"While crude and not totally accurate, yes that instrument is designed to stimulate your penis for the purpose of ejaculation." Zoban said in a slightly exasperated tone. "How else did you expect us to get a sample of your semen?"

"I don't know, maybe a couple of Asari dancers willing to get frisky for a few extra credits. I'm sure they'd be cheaper than however much I spent on that thing." Yolk said gesturing down with a slight head tilt as Daekon hooked up the pump to his cock.

Zoban shook his head. "We need to insure the material is untainted, other wise we'd just give you a magazine, a cup, and five minutes alone."

"Ptff, making a lot of assumptions about the size of the receptacle and how long I can last." Yolk responded with a smirk.

Zoban clicked a button turning off the intercom. "Oh, I'm sorry I shouldn't have expected so much from you, next time I'll be sure to reign in my expectations." Zoban let out a sigh, getting his frustration off his chest, then clicked the intercom back on. "Is it all ready to go now?" Daekon nodded his head, having just finished attaching the thick tube that ran from the end of the penis pump to the large holding containers. "Okay, I'm starting the device then."

Slowly the object on Yolks cock began to move, the segments of the device separating and moving upwards, then a couple seconds later retracting back down. Before too long it sped up, a rhythmic thump, thump, thump filled the room. Yolk initially felt strange with the mechanical object servicing him, but it was doing it's job well. It wasn't exactly like a real person, a little to perfect in it's repetition. Still, it's tightness and warmth was quite pleasant and he allowed himself to enjoy it. It took over five minutes for his cock to fully harden and grow to it's full size, straining the device to it's limit. It was designed to handle any normal sized Krogan cock, but he was now larger than any Krogan that had ever lived. For Yolk though, that only made the device even tighter and more pleasurable and he began to thrust into it, trying to get his dick even deeper.

"Impressive," Daekon said as he observed the Krogan continuing to fuck the device. It was an odd thing for a Salarian to say since normally he would never have been interested in watching another species effectively masturbate, but here he was feeling strangely enthralled by the whole experience. "You've been going for over 20 minutes and from your vitals, it doesn't appear you're any where near orgasm."

Yolk snorted, "Yeah, I guess you could say that. I can't get enough force and speed in these restraints. Can you loosen them?"

Daekon nodded his head. "Of course, they're no longer necessary so long as you don't move too much." The Salarian quickly tapped on his omnitool and the shackles around the Korgan's wrists and ankles released. Yolk sat up and gripped the base of the cock milking device, holding onto it and pulling his hips back, then slamming forward at the same pace as the machine itself extended and contracted, doubling the amount of work being done to his dick. The Krogan grunted his approval and gradually increased his speed, getting out of sync. Noticing this Daekon again tapped on his omnitool and adjusted the milking devices speed, setting it to over drive. Once Yolk hit the half hour mark, Daekon decided he required yet more stimulation. The younger Salarian licked his lips before speaking, "Looks like you still need more, I think I can help with that." He then accessed the cage around the Krogan's quad and used it to deliver very small pulses of electricity to stimulate pleasure in his balls nerves. This proved to be enough, sending Yolk over the edge. The tall Krogan let out a deafening roar as he erupted. Instantly the device engulfing his cock was filled to the brim and it began to vacuum out his spunk, delivering it directly into a 10 gallon container. The device had a near industrial level of transfer, yet even it was having difficulty keeping up with what his balls were pumping out. In mere seconds the containers were half full, and on top of that jizz was already spraying out around his shaft and down on his balls. Half a minute later the receptacles were completely full. It's seams began to get overwhelmed, with thick white globs of cum dribbling out of dozens of small holes. At the same time the tube bringing his seed to them was ballooning out, as its contents had no place else to go. At the minute mark the tube had swelled to the size of a human curled up into a ball and even the device itself was stretching and groaning. Then all at once they broke. First the tube burst spraying hundreds of gallons of steaming hot semen all over the lab, soaking machinery, computers, Yolk, and even Daekon. A fraction of a second later the cock milking device was torn to pieces as the Krogan's cock expanded yet again. His dick was now even larger and thicker than it had been after his initial injections, and he felt ready to go another round.

Yolk panted with satisfaction despite his cock still being rock hard. "That was the best orgasm I've ever had. Hehehe, wonder if that means I have a thing for machines." He joked, reaching down and flicking aside a piece of debris that was still sitting atop his wide cock's shaft. Daekon watched, almost seemingly in slow motion, as the black plastic chunk took to the air with a thick glob of the Krogan's steaming white seed stuck to it. A streak of his precious fluid trailed behind it, separating into smaller droplets. Finally it hit the ground, then bounced into one of the many puddles of jizz that now coated the floor. He didn't know why, but the Salarian found the whole sight hypnotizing and couldn't take his eyes off it. When he finally did, he returned his attention to Yolk but it wasn't the man's face. No, it was the magnificent meat rod that still strained for attention. Daekon took a deep breath, trying to regain focus, but that only made things worse. He had been faintly aware of the musk that the Krogan gave off, but now it was overwhelming. It was all that he could smell and it was driving him wild. His heart was beating fast and he felt a tightening in his pants. He felt like he could nearly orgasm just from being in Yolk's presence.

Daekon couldn't believe the kind of desire he was feeling. It wasn't normal for Salarian's to have such intense physical desires. Normally mating was a practical thing, something needed to continue the family's blood line. This though, it was different. He had only observed this kind of lust in other species, and as such he had no idea how to deal with it. He tried to push it to the side and be professional, licking his lips and finding his mouth dry as he started to talk. "I, uh... I should probably take some notes..." His eyes were still locked on the bright red throbbing dick. "And, maybe a few measurements. So uh..." Daekon swallowed hard using all his will power to finally tear his eyes away.

"Like what you see?" Yolk asked with a smug look on his face.

Daekon blushed bright red, something else that was uncommon for Salarian's. Usually they didn't get flustered enough for that to happen, but the realization that Yolk knew he had been stuck staring at the Krogan's cock filled him with an unusual mix of emotions. The most obvious was embarrassment and fear, but there was also hits of excitement and arousal. He tried to respond, but his mind was blank at what to say, so instead he just proceeded with his questions. "What was your typical length of time to ejaculation when aroused? We need to figure out what increase, if any, you have due to the treatment. The time we recorded was 27 minutes 22 seconds."

"I would say I had a considerable increase in endurance then. I would guess my average time before the treatment was 10 to 15 minutes." Yolk responded casually, then added, "Of course I also had a bit of a hard time getting enough stimulation. I don't know if that's because of my size, the machine just being less effective than a real person, or something else."

"Interesting, perhaps the stimulation you require to cum is directly related to your dick, er, penis's size" The Salarian replied, quickly correcting his slip into less professional behavior. The only thing keeping him from loosing control at this point was his focus on his job.

"Speaking of size," the Krogan began while lifting his heavy shaft, "how big am I now?"

Daekon was now in trouble, there was no way for him to avoid once again looking at the gigantic fuck rod, literally still dripping with hot jizz. The Salarian gasped, loosing control of his professional facade. His knees were so weak, they threatened to give out. Even his hands were shaking as he brought up his left arm and activated his omnitool. With some trouble, he managed to enter a command on the orange holographic display, activating a scanner. "My God! You're over 60 centimeters long and 13 wide. Even your amazing set of quads has increased with each one being approximately 8 centimeters in diameter. That's nearly 100% increase in every dimension, I would have never imagined this sort of growth was possible." The Salarian smiled a little, deactivating the omnitool and reaching forward. "In fact, I should confirm those measurements are accurate. After all, tools can be faulty from time to time." Daekon slowly wrapped his hands around the fat cock shaft, feeling the cum squish between his fingers. As his digits stretched around the Krogan's manhood, he couldn't help but note a couple of things. First, 13 centimeters across doesn't seem like that much when you just hear the size, but that's because it's hard to really grasp how that translates to circumference. The fact that even with his longer than normal fingers he couldn't touch tips really illustrated just how huge the manhood was. Second, was how unbelievably ridged Yolk's cock was. Daekon was straining against the flesh with all his might to stretch his digits just a little further, yet there wasn't even a slightl amount of give. "Fuck me, you're amazing." He no longer cared about hiding his feelings, he couldn't think about his professional demeanor any more. All that mattered now was this dick. He leaned his head towards the thick, helmeted tip. It's wide urethra dribbling precum slightly. "I need to know..." He gasped out, mostly to himself before giving the cock head a long lick. Warm and salty semen was collected by the Salarian's tongue. With a huge glob collected he pulled it back to his mouth, filling it completely. He could almost chew the cum, it was so thick, then he swallowed it with an audible and visible gulp. Once he got a taste, a single mouthful wasn't enough. He leaned back in and hungerly licked away at Yolk's dick like it was a lollipop.

"Just what do you think you're doing?" Zoban asked over the intercom. His voice conveyed just how much he wasn't amused by the situation and his subordinate's actions.

Without even pulling away or fully stopping his licking, Daekon responded. "I'm collecting some," slurp, "qualitative data about the subjects," gulp, "semen." Zoban scoffed at this and rolled his eyes, releasing the button for the intercom realizing he wasn't going to get a real answer.

Yolk smiled down at Daekon. He had occasionally imagined him, or one of the other smug Salarians down on their knees and servicing him, though he never really expected it to happen. At least, not without money being involved. "You're not bad with that tongue. Have you done this before, or does my cock just taste that good?"

"It's delicious, your cum I mean. It's sweet and salty, a delectable mix like caramel and sea salt. I can't get enough of it. That's not all though, even your flesh is intoxicating. I think... I think I could lick your cock for hours and still not be satisfied." Daekon said with pure lust as he finished cleaning the dick's head, moving down to the shaft.

"I'm glad to hear you're enjoying yourself. I'll allow you to lick my dick for as long as you wish, though I wonder..." Yolk stopped mid sentence, letting it linger.

Daekon pulled away for a moment, "What is it you wonder about, please tell me." The Salarian said, strangely desperate to know what the Krogan wanted.

An evil smirk crept on to Yolk's face. "Well, I was just wondering if my cock and cum was so delicious, what my quads tasted like?"

"Oh yes, I need to find that out!" The Salarian almost cried out, diving back in and redoubling his effort to lick his way down the dick. It took him over five minutes, but finally he had cleaned all the cum from the Krogan's shaft, now leaving the large man's cock glistening and clean.

Before moving on to his bosses huge balls, Daekon pulled away, spit stringing from his lips to the cock in front of him. "I can't take it any more, I'm so hot. Do you mind if I get more comfortable?" The young man asked in a pleading manner. Yolk looked down and saw the wet bulge in the alien's pants and just nodded his approval. The Salarian wasted no time, unlatching the front of his lab jacket and pulling it off, then pulling off his undershirt with one had as he undid his pants with the other.

In just a few moments Daekon was naked, his burgundy and salmon shaded body completely exposed to Yolk. The Krogan looked him over, taking in his strangely skinny form. What caught his eye the most was the smooth, slightly curved penis protruding from the slit between his legs. It was probably decent in size for his species, but to the Krogan it was absolutely tiny. The shape also left something to be desired. It was not unlike a gradually narrowing cone, that was rounded at the end rather than sharply pointed. At least it was leaking a decent amount of precum, something that would come in handy were he about to fuck someone, too bad for him there was no way he'd ever get a chance to use that on Yolk. The Krogan would hardly even feel it, besides he was the one who was going to be doing the fucking. Still he did have some mercy for the young man. It was clear that he needed some relief. "I don't mind if you touch yourself while you lick my balls." Yolk said in a tone that made it clear he was in charge.

"Thank you so much." Daekon said sincerely, immediately reaching down with his right hand. He started to furiously move his hand up and down his shaft. As he did he got down on his knees and crawled over to the Krogan. Yolk spread his legs apart, allowing the young man easier access to his quad. Daekon inhaled, smelling the musk even more strongly. It made him nearly cum instantly as his cock throbbed more fiercely than ever before. He reached back down with his right hand and started jacking it off like his life depended on it. At the same time he dove his face in, licking and sucking on the huge orbs between the Krogan's legs. Daekon gasped with joy. The Krogan's balls were glazed with his powerful cum, accenting it's flavor. The mix was just as delicious and intoxicating as his shaft had been.

All too soon for the Salarian, Yolk moved pushing the smaller man over. Then suddenly the Krogan was kneeling down with this gigantic cock looming above Daekon. Yolk put his left hand near the base of his dick, then slowly slid it up the shaft. This was the first time he'd felt his newly improved cock, fully able to take in how hard and heavy it was now. He couldn't wait to test it out. He pushed down on the top of his shaft, pressing it against the younger man under him. The cock was now so large that his penis was as long as the smaller man's whole torso. It's weight was almost crushing against Daekon, but what he noticed even more than that was how it felt rubbing against his own dick. The friction and heat of the massive shaft rubbing against him was heavenly, making him moan in bliss. Yolk couldn't help but notice this reaction, though initially he didn't realize the exact reason for it. Still, he was more than happy to go with it slowly moving his hips forwards and back. Moving his fuck rod about a third a meter as he went. Daekon quickly began to pant as the pleasure grew in him. Feeling a stud's cock working his shaft up and down was immeasurably better than his own hand. Even moving as slow as Yolk was, the Salarian knew he wouldn't last long. In fact, it wasn't even a minute later when he turned his head to the side and let out a long, high pitch moan of satisfaction.

Yolk felt a small splash of warmth on the underside of his shaft and chuckled. "So, that's what was driving you so crazy. I didn't even realize I was rubbing against your dick, it's so small." Daekon blushed, then smiled. He probably should have felt insulted by that comment, but he didn't care. No one could compare to a stud like Yolk, and he didn't want to. He just wanted to service him as best he could. "Now that you've cum, I think it's time you help me do the same. I've heard Salarian's are suppose to be flexible. I'd like to see just how much. Since you love the taste of my dick so much, how about you suck it properly?" The Krogan said in a cocky tone, standing up and releasing the younger alien from under his manhood.

Daekon eagerly stood up, needing his full height to be able to reach the tip of the Krogan's dick. He didn't hesitate or waste any time, greedily opening his mouth as wide as he could and engulfing the head. Even just the first few centimeters was straining the Salarian's lips. He pressed his head forward as hard as he could, but it seemed his cheeks just wouldn't budge, so he decided to suck hard on what little he could, hoping maybe his spit would act as lubrication. After a couple minutes he hadn't made any progress. "Is that the best you can do? I'm disappointing."

"I'm sorry, it's just... you seem like you're nearly as wide as my head. I don't have the strength to force myself to go any deeper." Daekon said, almost pouting in disappointment at himself.

"Hmm, I guess if that's the issue I could give you a little help." Yolk said, putting his hand on the top of the Salarian's head and pushing him back down towards the precum dribbling cock head. In just a second Daekon was already back down as far as he had previously managed. Feeling the resistance increase on the younger man's head, the Krogan exerted a little more force, instantly forcing his dick against the back of the Salarian's throat. Daekon's eyes bulged as his loud gagging filled the room. "Is this too much? Do you want me to stop, or should I keep going?" The Salarian's response was completely unintelligible, but to Yolk it sounded eager. "Good boy, here it comes!" The Krogan roared, pulling his hips back a couple centimeters before ramming them forward. In a single second 50 centimeters was slammed down the smaller man's throat. Near instantly the man's neck was stretched wider than his head, the outline of Yolk's cock pressed so tightly against it that even it's throbbing veins were visible. A fraction of a second later Daekon's stomach was bulging out even more than his neck.

Back up in the observation room the senior Salarian was disgusted by what he was seeing. This had gone way to far. It had been strange to see Daekon acting the way he was, but frankly Zoban hadn't really cared if he wanted to debase himself with their boss. At least it was providing some useful data, after all there were still numerous devices active in the room actively scanning the two. Had things continued to remain fairly tame, Zoban would have been fine with allowing them to continue. It that increase libido was just another side effect of the treatment. However what they were doing now was just wrong, and more than that, shouldn't be possible. It was true that Salarian's were a little more flexible than other species, but to stretch like Daekon was impossible. The lead scientist had to act now before things got even worse. He quickly made his way out of the observation room, and down the nearby stairs. As he went, he pulled up his omnitool to contact the security team on duty. He couldn't recall exactly who they were as he never had thought it was worth learning, so he didn't bother with any pleasantries. "Check your messages, I'm giving you emergency access to the security cameras in the operating room."

"Why, what's happening?" A female Turian voice came through the holographic tool.

"Yolk's gone insane." Zoban said as he entered his security code into the door of the operating room, waiting for it to open. "I'm going to see if I can talk him down, but I need you to watch and be ready to intervene if I fail." The door opened and hot air rushed out of the room. "I recommend heavy weap... oh..." The senior Salarian's had only managed to take a couple steps into the room before his body reacted to the musk now hitting him. It was much more intense than what Daekon had first been exposed to. His legs instantly weakened and gave out, making him fall to his knees in the presense of this god like Krogan stud. In the brief time it took him to get down to the operating room, Yolk had changed positions. Before, he had simply been sort of bent over as he pushed the young Salarian down. Now he was standing fully up right with his legs spread apart for better balance. Daekon was upside down, his mouth still fully impaled by the fuck rod buried deep down his throat and jutting out his stomach, the bulge being much more visible to Zoban now. Yolk had the small Salarian's leg in each of his massive hands. The size difference was so great between the too, it almost looked like Daekon was a toy. That notion was only made worse when the Krogan began lifting the younger Salarian by his ankles before slamming him back down. Up and down he went with increasing speed and ferocity, his mouth repeatedly slapping against the growing knot at the base of Yolks bright red cock.

Zoban was enthralled by the sight before his eyes. So much so that he barely noticed the first couple communications from security to him. "You cut out mid sentence. Is everything all right? Do you need assistance?

The lead scientist's mind was so clouded that he was slow to respond, but eventually he regained enough faculties to do so. "Uh, yes, everything's fine. I was wrong about Yolk, so very wrong. I mistook what he was doing as in sanity, but I see now... It makes perfect sense, in fact, it's the only thing that makes sense." Zoban grinned like a mad man as he continued watching the Krogan pound into his subordinate, using the younger Salarian like a cock sock. He hadn't even realized his hands had begun to move on his own, unzipping his pants so his dripping dick could spring free. As he continued to watch and jack off his own manhood, his mind began working. He knew that this was entirely counter to his normal personality and desires. Yolk had to be exerting some sort of mind altering effect. Was it telepathic, no that was unlikely as he wasn't effected till he physically entered the room. It had to be some sort of pheromon. Now that he thought about it, he was effected after inhaling. He also worked out that the intensity seemed to be increasing along with his own desire. It was unusual that it was effecting species other than just Krogan. Biologically Salarian's weren't compatible, yet it was still causing an aphrodisiac like effect. Would that extend to even more species, and what other compatibility might also be possible? Could Yolk procreate with females of other species now? There was only one way to find out, but before that Zoban needed some relief. His right hand continued to move up and down his dick, even as he forced himself to his feet and stumbled closer to the Krogan. He wanted a better view of the man, his gigantic meat rod pounding down Daekon's throat, more than that though he wanted to be the Salarian sucking that cock. Just imagining what it might taste like, what it might feel like to be stretched out by it, was too much. He fell backwards, moving his hand faster than ever before as he came hard, squirting several small bursts straight up into the air, right in front of Yolk.

The Krogan looked down at the elder Salarian, seemingly noticing him for the first time. Without even slowing down, or apperently being winded by the constant stimulation, Yolk gave Zoban a wink. "Don't worry, once I'm done with this guy, I'll give you a ride me too. Sound good?"

"That would be... Amazing!" Zoban said with glee realizing he no longer cared about what was going on with him, he just wanted... No, he needed that cock, he needed to pleasure that sexy Krogan. More than that, he needed to do everything he could to help him get even more pleasure. To that end he used his omnitool to access the ventilation system, rerouting the air from this room so it'd circulate throughout the entire facility. Then he collapsed completely to the floor, rolling his head to the side so he could continue watching Yolk work while masturbating once again.

Yolk continued fucking the younger Salarian.. As he did so, Daekon got even more into it, sticking out his tongue and doing his best to lick at the man's balls when he was close enough to taste them. When the knot prevented that, he simply switched to servicing it. Finally, after nearly 35 minutes, Yolk was reaching his limit. The fast, rhythmic pace he had been using for most of the time became rougher and more erratic as he tried desperately to force his fully engorged knot to push past Daekon's lips. Even with the Krogan's significant strength it was giving him trouble. That was until he entered a blood rage like state, ramming the whole thing down the Salarian's throat. Daekon's cheeks stretched more than ever before, almost doubling the width of his head. Yolk let out a satisfied roar loud enough to vibrate Zoban's bones, as he laid on the floor watching. The cock buried deep in the smaller man's body twitched and throbbed visibly through the Salarian's stretched flesh as the first burst of cum traveled the length of his manhood. Then, in almost an instant, a gallon of cum was delivered straight into Daekon's hungry stomach. Then another, and another, it kept coming twice as fast as when he had been milked by the machine. The Salarian's belly expanded rapidly. In just a couple seconds he was as large as a human nearly ready to give birth. At 30 seconds his belly was stretched several meters wide, with the flesh so tight that the cum sloshing around inside of him was actually somewhat visible. He wasn't able to get much wider than that though, as cum began to spray out around his lips, nose, and ass.

Cum was pouring out of the younger Salarian as quickly as it was being pumped in, and Zoban found himself energized by the sight. He pushed himself to his feet and came closer, licking at the Krogans balls to taste both them and the seed flowing out and over them. Then something amazing happened, they started to grow larger. Just like last time, his orgasm triggered an increase in size. Inside Daekon the same thing was happening, only instead of simply stretching him out even more, Yolk was at the perfect angle for something amazing to happen. His cock grew longer and thicker, seemingly straightening out the smaller man's bowels, then his rounded cock head began spreading the man's anus open. When Zoban realized this he gasped. This was so wrong, so many things said this was scientifically impossible, yet all he could do was react in awe of the sight. Several centimeters of Krogan cock emerged from Daekon's ass, still spray steaming hot jizz. Not wanting to waste any of that precious seed, the senior Salarian quickly moved up and wrapped his lips around the dick head, bobbing his head up and down it as much as he could. The salty sweet taste was heavenly, and he came once again, this time solely from the studs cum. His belly quickly expanded till it was over half a meter around before Yolk was finally done cumming. The Krogan roughly pulled his knot free of Daekon's mouth, which also pulled the cock back into the man's body. Daekon gave his lab partner's anus a few licks to collect the remaining cum from it, then stepped back. Yolk then pulled himself the rest of the way out of the younger Salarian, who had passed out from the exertion and constant orgasms, dropping him into a puddle of his steaming hot seed. Cum poured from his stretched mouth and ass, slowly deflating the man back down to a more reasonable size.

Now free of Daekon, Zoban was able to see Yolk in all his glory for the first time. "You've grown again. I'd guess you're now three quarters of a meter long and probably 20 centimeters wide. That's so big, too big. You're going to wreck anyone you fuck, you know that right?" Zoban said with a crazed smile as he bent over a nearby medical bed and shook his ass at the Krogan.

Yolk grinned and walked over, pushing his cock up against the Salarian's butt and rubbing it up and down his toned rear. "You're probably right, but it didn't sound like a complaint. So if you're not scared, I suggest you spread your ass already." Zoban gasped at both the touch and the words. He wasted no time and did as he was asked, grabbing his butt cheeks and spreading them apart as wide as he could. Of course this was nothing compared to the size of Yolk's tree trunk of a cock, but at least it was a little easier to aim. "Heh, good choice." The Krogan grunted, moving his hands up to the Salarian's shoulders to brace him. The were comically huge in comparison to him, with each one almost being as wide as his torso's width. He didn't have time to really consider this though, as Yolk gave a single mighty thrust ramming himself into the man's tiny frame, only stopping short of pushing his knot in too. Zoban let out a yip of surprise at the quickness of the massive alien's movement. Instantly the smaller mans normally flat and thin belly was bulging out half a meter in front of him. He was stretched even tighter than Daekon was, and the dick hollowing him out was even better displayed because of it. His belly was thinner than a condom and he loved it. Then he watched it slowly shrink away as Yolk pulled himself back with a low, satisfied purr like grunt. Once he was almost fully pulled out, the Krogan drove himself back in even harder than the first time. After just these two thrusts the Salarian's cock was back to full mast. Zoban could feel himself already nearing another climax. He wondered how anyone could be this good at sex, but quickly lost his line of thought as the blue tinged alien pulled out again, this time much faster. On the third thrust into the Salarian's strained anus Zoban let out a scream of glee. Several wads of his thin alien cum splattered against the underside of the medical bed. From that point on, everything was a haze to Zoban. His dick never soften even a minute amount, instead the constant overwhelming stimulation of his ass being reamed mixed with whatever effect Yolk's musk had meant he was riding one rush of pleasure to the next. No, it was more than that, they were compounding and growing stronger, like a tidal wave. When it finally hit with full force, he wasn't sure his mind would be able to take it and he didn't care. With this kind of bliss, what did it matter.

The Krogan noticed the change in Zoban's attitude and demeanor. Despite the Salarian's eagerness to get fucked, he still had hints of his smug attitude at the start. His body language still showed that he thought he was somewhat in control. After just a couple minutes though he was looking more like an eager slut. He was panting constantly with his tongue hanging out limply as he let out an endless series of moans, gasps, and whimpers. His previously tense and rigid posture was completely gone. He was now so relaxed and given over to pleasure that Yolk could contort him anyway he pleased. After a further 10 minutes of pounding into the bed, that's exactly what he did. He was bored of that position now, and the bed had slowly been destroyed under the constant jack hammering of his cock head into it. With one mighty thrust he rammed himself entirely into the Salarian, including his knot which brought Zoban to instantaneous orgasm and bluged out his belly more than ever before. Yolk didn't even give it a second thought, repositioning his alien fucktoy so that his face was smashed into the floor while his ass was raised up into the air. The Krogan putting his right hand on the Salarian's head, sliding his pinky and thumb around the outside of Zoban's horn's while his middle finger slid right in between them. With him now firmly held down, Yolk tore his knot and cock completely free of the alien's abused ass, curious to see how much of an effect he was already having. The Salarian's anus was gaping wide as a grapefruit, but also appeared to already be slowly shrinking back to it's normal size, or at least something close to it. Satisfied that no permanent damage would occur, the Krogan rammed his cock in with all the force he could muster. This of course once again knotted Zoban, making him ejaculate on his own face. Yolk proceeded to saw his cock, knot and all, in and out of the Salarian at break neck speed for 15 minutes. The tightness and warmth that his fuck toy was giving him was amazing, but still not enough to cum from. Not yet at least. If he kept this up, he was sure he'd eventually erupt, but he wasn't done experimenting yet.

Yolk recalled his cock going all the way through Daekon. It had been from the opposite end of course, but there's no reason to think the reverse shouldn't be just as possible. Of course, to do that he'd need more control than he had now. With his entire cock sheathed in the other man's ass, he grasped Daekon's head and horns then pulled him back as he stood up. He moved his left hand on the Salarian's right shoulder before releasing his head. In one quick motion he spun the alien 180 degree's counter clockwise on his cock so that he was now facing upwards. This had the secondary effect of also introducing a new sensation to Zoban, feeling torque being exerted on his now extremely sensitive ass. The new feeling gave him his biggest eruption yet. His eyes rolled into the back of his head and he sprayed Yolk right across his chin and lips with steaming hot semen. Yolk just smirked, then licked his lips clean while moving both hands on the side of Zoban's body. He then moved the Salarian till he found the most natural angle for his cock to move. Holding the alien in position, popped his knot free, pulling back half a meter, then slamming forward. With a blur Zoban's head jerked back with his throat stretched out like a snake engulfing a rat. His mouth stretched open impossibly large as a fat throbbing dick head shot out over 20 centimeters. Yolk held himself there for a moment, admiring his work and size. Then he heard what he thought was choking, but as he listened closer he realized it was something much more enticing, the sound of desperate sucking. Zoban was now so completely enraptured with pleasure that Krogan cock was all he knew. Even as his whole body was penetrated, he just wanted more, so that's what Yolk gave him. It felt amazing to both men. Yolk got to experience two sexual acts simultaneously. The heat and tightness of the man's ass along with the moist desperate sucking was made all the sweeter by the brief cooling feeling of his wet tip in the gentle recirculated air of the room.

For 20 more minutes the Krogan fucked his Salarian cum dump, penetrating him all the way through with each thrust. Finally Yolk was again at his limit. He pulled his cock back till he was half way inside Zoban. He changed his angle slightly, ramming back in all the way while his right hand moved up over the Salarian's mouth. Yolk let out one of his now familiar roars as his balls began dumping seemingly endless quantities of hot jizz directly into Zoban's stomach. Rapidly his belly grew larger and larger till it was twice the size the first Salarian had managed to contain. Finally, just when it seemed he might burst Yolk released his hand letting his cum spray from Zoban's mouth like it was a fire hose. It was so fast that his belly was actually very slightly shrinking even as the Krogan continued to pump in more baby batter. It took over five minutes for him to finally slow down to a gentle trickle, and a further two minutes to stop completely. When Yolk was completely done, he realized the Salarian had passed out. The Krogan just laughed, he should have known he couldn't handle all that. He pulled the limp man off and casually tossed him on the half destroyed medical bed. He looked at Zoban, the man's chest slowly heaving up and down while his still bulging belly continued to shrink as cum poured out the agape anus. Yolk smiled and turned, making his way towards the door. With luck, those cute Turian girls he hired for security would be a bit more resilient. He would really like to hear them scream out in bliss as he cums. If he was really lucky, maybe he'd even be able to knock them up!
