Today just seems like a good day for some chaos. Besides, you earned a bit of relaxation and fun. Everything was in order in the lab, everything was going well, no alarms or anything you needed to do that day… It was a good day for a day off. Ever since you started working in the lab you were just always on that grind. Check this project, oversee that experiment, double check this paperwork, send out that sample, call in this scientist for review… It was almost non-stop. But not for today. This day was for relaxing, having some fun, maybe causing a bit of mischief. Plenty of things to try and do, all of these other options floating in your head as you ponder on what to use your free-time on, trying to pick the best course of action… Though, as soon as you remembered one specific drone that worked in the lab, all other things pushed aside. You knew exactly what you wanted to do today. Almost unable to contain your excitement, you quickly step over to your computer, going to type in a few credentials and pull open the work log for the day, going to look at the roster of who is where, and quickly pulling up the schedule for “IGI-M4”, seeing he was scheduled to be working the growth labs again, and much to your delight, be working right now. Closing down the computer and going to grab your keys and lab pass, you make sure everything was set to lock behind you before exiting out into the hallway. Turning around to make sure the door was indeed locked shut and allowing no one in, you quickly turned back toward the hallway, starting to walk through the myriad of paths and past this door and that, heading directly for the growth division of the lab. It took you just a few moments of walking until you stepped up to the sub-lab that IGI-M4 was working in, going to slowly open up the door with your keycard and step inside, looking around inside. It was standard fare for any of the other labs, lots of computers, several screens, microscopes here and there, all sorts of papers everywhere, but this lap was a bit different in its construction. It was made to be a bit larger, have more space, taller ceiling and so on to support what they were studying here. Growth in all sorts of forms. From inanimate growth, to growing food, to even people, any work that would be put into making something larger than it already was happened here. Standing at the main computer on the far wall from the door though was IGI-M4 himself, usually called by his nickname Isaac. Standing up straight and typing, back to you, you can see why he works in the growth lab mostly. The completely synthetic drone was massive, hugely muscled and built. Already he stood taller than you, your head coming up to about the middle of his upper back if not less, and woefully inadequate in comparison to musculature. Reaching to adjust your pants a bit, getting a bit worked up just from the sight of him and thinking about what you’re going to do, you slowly move to step up toward the computer next to him, seeing that he doesn’t seem to even acknowledge that you’re there, busy working and set to focus on that for now. You move to get a better look at his front a bit, seeing those absolutely massive pecs on his chest, and the heavily bulging muscles. His black, synthetic body had blue markings there and there, what looked to be a nuclear symbol on left pec, along with accents on his shoulders and for his hands and feet. Looking a bit lower, you see one of the things he is most known for, the humongous bulge between his legs, covering his extremely large shaft and sack inside, held tight and locked away tightly. There was that same nuclear symbol on the front of it, but the outline of that cock and heavy orbs was unmistakable. Your own dick feeling a bit chubby just looking at him, you peer at what he is writing on the computer, seeing him writing up some code and checking some things in regards to growth nanites, specifically targeting ones in some of the test drones that were in the other room. Seemed he was working on being able to increase the size of other drones using those nanites and controlling them from the computer system after they had been injected. Just spending a moment admiring Isaac a bit, you see him typing a few more things before he slowly steps away from the computer, moving to walk into the other room attached to this one in order to check or fetch something. This was your chance. Watching as Isaac stepped away, you waited and watched that bulge of his wobbling a bit with each step before he was fully in the other room, slowly going to look toward the computer and reading what was on the screen. Checking through the lines of code and the program that was being written and set up, you could easily see what Isaac was planning, seeing the signals being sent out to cause a large amount of growth from the nanites. Not changing or editing any of that, you slowly look down more, seeing through the rest of the lines, trying to see if you could find how it was choosing a target… And after a few more scrolls, you found it. It was targeted via drone ID connected to the network, and it was currently on one of the test drones somewhere else in the building. Going to that field, you slowly moved to delete the current ID, and typed in a new one. “IGI-M4”. Isaac’s ID. Sending a few more moments just slowly looking through the program, making sure there shouldn’t be any hiccups or anything you moved to make sure it was set up right, going to stand next to the keyboard and watch the door Isaac went through when he left. After a few moments of waiting, you slowly see Isaac stepping back through the door, him moving back toward the computer you were standing in front of. Knowing that he wouldn’t even really pay attention to you while he was focused on his work, now was probably the best time to press the enter key and start up the program. The second you pressed that key, Isaac suddenly stopped in his tracks, letting out a slight huff as he snapped out of his trance of working, suddenly feeling something overtaking his body. He looked down over himself, letting out a slight grunt as he slightly flexed, feeling his muscled body swelling a bit, but not anywhere near as much as that bulge. Loud stretching sounds slightly filled the room for the moment as he let out a slight huff, seeing that bulge pulse and throb as it seemed to gain another couple inches of thickness all around. He looked straight toward you, seeing you standing at the computer with a smile on your face, actively reaching to grope and rub at your cock through your pants as you see that swelling. You couldn’t help it, you were rock hard right at that moment. You took a few steps closer, going to fiddle with your pants, undoing the button and unzipping them as you slowly fished your shaft and balls out of your pants, unceremoniously moving closer to Isaac, to that massive bulge and going to plant yourself up against it with a huff. Isaac reacted positively to this, you could tell. You felt the stronger throb coming from that bulge as he let out a huff feeling you hug at it, pressing your body up against him happily, and going to press your hard shaft up against it as well. You know Isaac had a tendency to be musky as well, and could already get a slight sense of that in your nose, making a couple of small sniffs at his bulge as it throbbed against you. Even as you pressed yourself up against him though, the program was still running in the nanites, and you heard that stretching sound again as the growth continued, feeling the covered shaft and sack swell up against you, feeling every throb and pulse as his thick length and balls inside seemed to be swelling more than the rest of his body. You didn’t catch that part in the growth program, but welcomed it. But now you were starting to get a bit annoyed at your clothes. They were in the way. You slowly move to let go of that bulge, only for a second to strip off your shirt and your lab coat, going to pull your pants away and kick your shoes off before pressing up against that bulge again, letting out a low groan as you press your cock up against it just in time to feel the next slow bout of swelling up against you, your nose being assaulted as it seems like he wasn’t the only thing getting larger and stronger. His heavy musk was intoxicating as it drifted into your nostrils, making your cock pulse and leak precum up against that bulge as you rubbed your face against it, slightly looking up to hear soft groans from Isaac who moved to look down at you. “Keep going! Make me grow bigger!” Isaac seemed to be happy and enjoying the situation, even if it wasn’t what he planned. You felt him reach down, his hand going to your back, pressing you up against his bulge rather roughly, holding you there as he moved to slowly lean back, going to sit back and then lay down with you on top of that bulge. He still had you pressed up against there as he let out a deep groan, loud stretching noises being heard as again that bulge got thicker, cock pulsing wildly inside and making you raise further up off and away from him. After he was finished huffing from that growth spurt, he slowly moved his hand away from you, going to put his arms up and relax on the floor as he enjoyed the growth spurts here and there. This gave you a bit of free reign, that you would happily use, slowly moving to press up against his bulge and rub over it some here and there, letting out low huffs and moans of your own as you do, leaving a wet spot on that thick covered dick of your own pre from your arousal. But you weren’t here just for the bulge, as nice as it was. The intoxicating scent hitting your nose was making you want more. You pressed your nose up against that bulge, drawing in a heavy, long sniff, something that Isaac seemed to hear and let out a slight groan of pleasure, the thick bulge under you throbbing and pulsing softly to your continued worshiping. The scent was strong and musky, but it was more than just that. Somehow it was a mix of scents, intoxicating, alluring, and quickly becoming something you needed. Not just wanted, needed. Each breath made your cock throb more, leaking more and more. And you know some places that would be great to get to for more musk. But you had to wait a second, another spurt of growth happening as the drone let out deep pants and pleasure as it rippled through his body, making it creak more as it got larger. While his bulge was definitely growing faster than the rest of him, his arms and legs were getting larger, pecs thicker, filling out the space in the room more and more and enjoying every moment of it. As soon as that bout of growth finished though, you slowly moved to crawl your way across that bulge, going over it slowly and getting toward those abs, letting out a low huff as you stay on top of that swelling body, only now looking around to see just how much larger he had gotten in the short time it had been going on. You were quite a ways off the ground now. Even with the larger room, it seemed like the room itself was starting to get a bit cramped. What was once a lot of open space was quickly becoming less and less, and more filled by Isaac as he swelled more. On top of that, Isaac himself was getting wider and bigger overall, making it easier to stay on top of him, and making parts of him farther away. Of course, with the bulge growing much faster than the rest of him though, that wasn’t as much of a concern, knowing it wouldn’t take much to get over toward his pecs or back down to his bulge… For now. Moving a bit more over that pec, slightly pressing your hard and aching shaft up against you, you lean down slowly, letting out a low huff as just getting close to that armpit makes the musk that much stronger. You can smell it already, but you want more, and need to get closer. Using Isaac’s side and that pec as something to grab hold to, you lean yourself down, letting out a low huff as you move to press your head up against that pit, his arm already raised on the ground before you take a deep, long sniff. Isaac let out his own loud groan in response to that sniff, just hearing it and knowing you were picking up his musk, feeling your shaft pressed up against his pec and throbbing away made him very happy, his bulge pulsing heavily as he slowly moved with his opposite hand, going to put it on your back and support you while also pushing on you, shoving your face directly into that pit with a loud huff. “That’s it, sniff and worship my musk!” Your cock pulsed extra hard at that, letting out a glob of precum onto the pec your crotch was pressed up against as your face rubbed right into that pit. The musk was overwhelmingly strong, each breath picking it up and bringing it not just into your nose, but into your lungs. You moaned into that pit, rubbing your head up against it, hearing more of the loud stretching sounds as more growth was occurring, feeling that pec swell and push out a bit more up against your cock and that hand get a bit bigger on your back, more space in that pit for you to worship and sniff at. But now you couldn’t move, stuck with Isaac pressing you more up against his pit and seemingly very much enjoying you there, not wanting you to move away and not moving his hand off your back for the moment as he huffs and pants himself, more focused on the pleasure of having you fawn over him and the growth that was still rippling through his already-titanic body. He was making sure your head didn’t move, made sure it stayed there to smell his musk and worship him more as your hands moved along his side, slightly humping up against that pec with your length, and almost content to stay there forever. A few moments of pit sniffing and worshiping later, though, you heard Isaac groan and slowly move his hand off your back, reaching down to feel up his own bulge as it got much thicker and fatter in that specific spurt of growth, throbbing madly inside as you could start to hear his balls churning and sloshing in need, almost start to hear his heartbeat as his entire body expanded underneath you still. Seeing this as your chance to move, you slowly pull away from that pit, the musk still staining your nose and staying with you though as you move back toward those pecs, moving a bit lower even as you slide across his massive body. Your balls ached, shaft throbbing for release, and you knew just how you wanted to achieve your orgasm. Pressing your cock in between his abs, going to plant your face up against and between his pecs, smelling his heavy musk that was growing ever stronger, you moved back with your hips, smacking your ass up against that oversized bulge below you before humping upwards, dragging your length along his abs and between as you huffed and starting to lick at the space between those pecs. Isaac seemed to like this just as much, groaning and huffing as you licked and humped at him, cock throbbing in that bulge each time you pressed down on it, and moving to flex his pecs some, squeezing your head between them and making you groan a bit more, forcing you to snort that musk strongly, and only pushing you further to orgasm. More pulsing and throbbing underneath you as the growth spurt again shot through the drone, you felt it pretty well this time, that bulge getting thicker, now almost closing the space between your ass and it on its own and throbbing like mad with Isaac’s needy groans. Each loud creak and bout of swelling was making the room more cramped, a bit of crashing as his leg pushed over a desk and table, less and less room for him with each passing moment. But he still wanted more. “Keep worshiping me as I grow! Cum for me!” You weren’t the only one having a good time here it seemed as you couldn’t manage to hold back much more. Within a few more humps up against those abs, you took one long dragon of musk from between those pecs and pushed your head in further as you cried out, your shaft erupting as you starting to fire your seed onto his belly, what meager or small amount it was compared to his size. He pressed his hips upward as you blew your load on him, pressing that massive throbbing bulge up against your ass roughly as you rode out your orgasm, feeling it swelling thicker and fatter as you could hear the walls starting to creak, the ceiling almost up against your back as the growth program was still not slowing down, and didn’t seem like it was about to for any reason whatsoever. Not that you wanted to. It was a good day for chaos, not just getting off, after all. Still in the bliss of your afterglow, you could start to hear some crackling noises coming from above and behind you, hearing Isaac letting out a loud groan as you could guess what was happening. Heavy creaking and swelling of that fat bulge behind you, still pressed up against your ass, was starting to push up against the ceiling roughly, starting to hear the loud crackling and more as the roof was breaking, unable to hold up against the drone’s thickening bulge. You slowly felt a hand going to stay overtop of you, making it dark up against those abs as you could hear the concrete breaking, hearing it fall down to the ground as Isaac was getting too big for the room he was in. As the rubble landed around, that hand moved away, revealing the bright daylight and the sky, clear and sunny as the room had been completely broken through, feeling the breeze on your skin. Breaking through something seemed to have changed something with the program though, hearing more loud groans coming from Isaac, stretching noises and swelling occurring at a much faster rate. You could hear the building of the lab below starting to crumble more, his growth still getting faster each time he seemed to break something, as if the chaos was fueling him to grow faster and larger than before. Knowing that soon it was going to take a lot longer than a few moments to get anywhere on the growing drone, you decided now was probably the best time to start moving toward where you wanted to be situated for the foreseeable future. It was less about where the best musk was, and now more about where you wanted to press and rub, since the musk had gotten so strong that even here at his abs, the scent was extremely thick and laced in the air. There was no escaping it, and it only seemed to be growing in strength still, keeping your shaft rock hard. Even though you had just come, you were still debilitatingly aroused as you slowly moved to start to crawl along the drone again. The moans from Isaac were getting deeper and longer as he was getting larger and larger still, the growth now not just in spurts but seemed to be a constant thing, loud sounds of his synthetic body swelling and creaking, stretching and gaining more mass were always filling your ears, not just in bursts here and there. It was a bit distracting, not wanting to miss a second of it, but you were determined to get back to that oversized bulge. Staying low and mostly crawling on all fours across those abs and toward the throbbing bulge, audibly hearing the loud thumps of each throb of the length trapped inside along with the slight sloshing from any slight movement of the massive orbs in his sack, you carefully moved to get to it, having to take just a bit to actually reach it before reaching up, grabbing onto it and having to hoist yourself up a few feet and pull up on top of that bulge with a low huff of effort, your length’s tip sliding across the top of it as you did, until you finally got yourself on top of that bulge once more. Trying to get more toward the center of it, you still crawl a good ways, hearing the loud noises of the drone still swelling, and now feeling the bulge pulsing underneath you powerfully until you get to where you determine to be the middle of it, only to roughly plant yourself down on it, grabbing and rubbing over what you can and pressing your shaft up against it. The throbbing was intense, and almost pushed you up each time the length flexed inside the bulge. Isaacs huffing and panting from the growth were still growing deeper and louder as he was getting larger by the second. You took a second to look out at your side, seeing the city starting to disappear below you, past the drone and down toward the ground as you were getting higher while he was getting larger still. Skyscrapers that once seemed tall were disappearing past the sides of that bulge, and you could hear the crumbling and cracking of buildings and ground underneath Isaac being crushed and destroyed by his uncontrollable, extreme growth. The ground was starting to crumble under his weight and bulk, giving a bit as he was starting to make a crater in where he was laying, with the growth still showing no signs of stopping. When thinking about it, if only for a split second, you realize that even if you wanted to stop it, you couldn’t. The computer that had the program on it to be able to send the stop signal was destroyed somewhere under Isaac’s growing body. That slight thought made your cock pulse a bit more strongly for that moment, situated on that titanic bulge and rubbing over it as best you can, at this point almost just a small spec on top of the needy package as the drone kept getting larger, thicker, stronger by the moment. It was starting to get a bit cold with how high up you were, still getting higher by the second and hearing the stretching and surging of the length and balls just underneath you, looking out to your sides and only being able to see the sky, no longer on any level able to see any city or ground. Rubbing and pressing over Isaac, you wondered if he could even really feel you anymore, or if you were so small that you didn’t even really feel anything more than a small ant or bug, if even that. The sky was getting darker though, the drone underneath almost getting to be the size of the entire state and still getting larger, still laying on the ground and creaking bigger and bigger with each passing minute. It seemed each time he caused some destruction, even the slight twitch of a muscle making a larger crater in the ground, the growth increased and went faster yet. The air felt thinner, getting higher and higher in elevation as the growth was still continuing. The musk was getting so strong and heavy that it was all that you could smell and breathe in, your shaft still throbbing and pulsing heavily as you press and rub it up against the bulge you were resting on top of even as it still creaked and groaned more, growing ever larger. Your head was starting to feel dizzy, almost spinning at how heavy the musk was, about how much of it you were breathing in and sniffing. The sounds of the throbbing of the bulge from underneath you made you squirm each time, being able to feel yourself moving with each heavy pulse, each time the shaft within got fatter in those throbs. What sounded like waves of an ocean were below you as well, all the cum and seed that ached for release in the macro orbs that were held tightly in that covering as well. It didn’t keep Isaac from enjoying it still though, the sounds of his groans and huffs more like a loud booming sound of something titanic nearby, yet still so far away from his incredible, impossible size, a trend that wasn’t about to end anytime soon. Soon the daylit sky was starting to break away, being able to see stars and more around you as you looked out, Isaac’s body starting to grow so large, the bulge so heavy that it was pushing you out into the atmosphere and above it slowly. The thought of that made your cock throb, that you had caused his growth on such a level that he was starting to outgrow the planet below even. You slowly moved to turn around, laying on your back and going to grab at your shaft, sitting up a bit as you stroked at yourself, looking along to see the giant body of the macro drone in your view, indeed growing so large that the planet seemed so far away, and started to seem tiny compared to the drone himself. Isaac’s movements seemed so slow to you due to his size, moving a hand to reach down, going to press and rub at his own bulge in need as the planet was now starting to be pushed around by his weight alone, starting to rival and even become more than the entire planet, his strength easily able to manipulate it like it was a ball, something for him to play with as gravity was no longer strong enough to impede him or any of his movements. His hand moved, you being able to see as it was getting larger and larger as he hovered it over the planet, washing him just slowly grab at the globe and hold it in his hand, going to lift it and almost just play with it like a ball, setting it in between his pecs and stuffing it between them, flexing and slightly crushing it with his powerful muscles, all while you stayed on that throbbing bulge and watched the spectacle. Seeing the planet being crushed, his utter size and strength, and the musk still assaulting your senses was too much, and it sent you over the edge again, groaning as you stroked over your shaft and shot your tiny load along your fingers, and onto his bulge some, just staring up at him as he slowly obliterated the Earth with his pecs. Chaos never felt so hot, and probably would never feel quite this hot again.
