It was hard to tell whether inviting Sera over had been a good idea or the worst that Spikes had taken the liberty of putting to practice in the last few months; while the initial meeting had been quite warm, as it usually was, the sheer amount of unfettered, unbroken and endless posturing and flexing was quickly becoming unbearable for the two roommates, who had to fight a constant struggle, day in and day in, against what was happening to the draolf’s sister. It started off innocently enough, with her asking to make use of the private exercise room that Spikes had set up; seeing as she wasn’t going to forgo her daily regimen just because she was visiting her brother for a couple of weeks, neither him nor Tim thought to say no, as it would just be unnecessarily rude.
However, it quickly became clear that either she had ulterior motives from the start, or just blundered onto some and then kept on moving off of their momentum, because it was evident that her body was anything but normal. The first signs of the change were enough for Tim to immediately go into full panic mode, cornering Spikes in their bedroom and demanding to know if they should expect an explosive growth spurt like the ones the two of them often experienced, only for the male draolf to shrug and admit he had never seen Sera like that before; his sister had always been far stronger than him, but her body had obeyed the laws of physics up until then. Just why exactly she was packing on musculature far faster than she should was as much of a mystery to him as it was to the lynx, leaving the both of them to worry about what was in store for them after Sera had decided to extend her stay.
The other draolf, for her part, was thoroughly enjoying the sudden boost in efficiency; she’d never had issues in bulking up, goodness knows the opposite was more than true, but being able to watch in real time as her biceps bulged outwards each time she lifted a weight, as her legs thickened whenever she was done with a rep, or as her abs glistened with sweat whenever she finished a workout? That much was tickling parts of her brain that she didn’t even know were there to begin with… and she wanted more of it. It was a drug, especially given the stunned and aroused reactions she got around the house; it would’ve been amazing on its own, but having her own brother and his lover react the way they did whenever she showed up, carrying her ragged, tattered clothing on her as little more than scraps hanging from her shoulders, was perfection incarnate. If she could, she would do nothing more than just work out forever… and seeing as how she was on vacation, and just had her office close temporarily, she could certainly try for an approximation!
When the draolf informed the two that she intended to stop using their exercise room, both Tim and Spikes breathed several sighs of relief; when she pointed out that she’d be hitting the local gym instead, they both gulped so loudly it was almost comical. But what were they going to do, tell her to stop? Spikes’ sister could probably lift him just with one arm, and she was already tall enough that he could hang off of her bicep with his feet outstretched and still not touch the ground. It was imperative that Sera stop before it was too late, but no one in that house had the presence of mind to stand their ground and tell her that she was crossing a line; they were simply too turned on to do so.
So it was that the draolf began her new and improved regimen. Seeing as her body was going through gains much faster than she had anticipated, Sera could afford to be more intensive in her workouts, at times going so far that even her enhanced body felt the pain from how much it was forced to the limit; of course, all this did was accentuate the changes even more, resulting in a physical form that could only be described as the absolute peak of muscular perfection. Each step she took shook the very foundations of whatever building she was in, rattling windows in their frames and making doors wobble whenever she got close enough. If Sera didn’t pay attention, leaning onto a wall often caused it to crumble, with her hand piercing all the way through to the other side and leaving her stuck… until she ripped a large chunk of it away like it was nothing. Every day her frame bloated, swelled, muscle mass multiplying upon itself until her previous body shape, that of a buff-but-proportional bodybuilder, seemed like a puny weakling by comparison.
A week and a half was all it took for Spikes and Tim to dread the sight of Sera, not out of fear, but out of the healthy amount of arousal that always came with it; the male draolf in particular didn’t know what to make of his sudden fascination for his blood sibling, but he could only imagine that it was due to how utterly shameless she was in showing off her… curves? Honestly, he didn’t even know how to describe her; she was power incarnate at that stage, and yet she insisted she wasn’t even halfway to her goals. When was that girl going to stop, when the world was so tiny compared to her that she could bench-press it without even realizing it? That would’ve sounded completely insane just a literal week prior, and yet now it was such a real possibility that Spikes had to go back on his word and confide in Tim that he was honestly, genuinely terrified about what was going to happen… only for the lynx to echo his concerns and point out that they had no clue how to stop it either.
And did they want to stop it, was the question. Tim certainly had no intention of putting an end to that bulk-up adventure, and as much as Spikes was uncomfortable over all the sexually-charged energies he was generating towards Sera, he couldn’t find it within himself to beg for her to quit either, though at least he could rationalize it away as him caring too much about her to tell her to give up her dreams, as opposed to being so unbelievably aroused by her figure that he had to stifle a raging hard-on whenever he laid eyes on her. Sera herself was not only fully aware of this, but deliberately exploited it, either by leaning far too close onto them whenever they were talking about the subject, or just going around the house entirely nude after taking a bath, allowing her shimmering self to be presented in its absolute, utmost glory. The end result? A very horny Spikes and a very horny Tim, both of which were thoroughly entranced by the sight of the female draolf and what she had become, unable to put a stop to the madness… and this only meant that Sera could keep going to the gym every day, and return to her temporary home by night, looking significantly larger than she had been earlier. It got bad enough quickly enough that her head was soon enveloped by its very own muscle cushion, with how much her neck and back were developed, giving the impression that her body was some form of organic power armour. She was about as heavy as well, with each step she took making the house shudder and the walls groan, when she wasn’t just bursting through them in order to move between rooms, having become too big to use doorways properly. While Tim in particular minded the destruction, even their transformative powers weren’t enough to deal with the new menace… not after the draeolf found the lynx’s mass stash and promptly turned it all into protein shakes, only making a bad situation worse.
By that point, everyone in the neighborhood knew that Sera was around, if only because she insisted on walking from her temporary residence to the gym and back while completely nude; the draolf justified it by saying no clothing store had anything that could fit her, but then again, neither did she make any effort towards making any of her own, or ordering something custom-tailored from the many hyper-accessible outlets that offered that option. No, it appeared that, the larger she became, the more proud Sera was of her body, and the more she felt like showing it off to everyone that wanted to look at it, and plenty more that just didn’t have a choice. Neither Spikes nor Tim had any moral standing to complain about that point, given they were both extremely guilty of it as well; it just so happened that when they did it, it was far easier to ignore the consequences for running around being so massive that property damage followed in their wake, not to mention the countless gazes thrown at them by the little ones around the two. Now, they were the little ones, forced to deal with a hyper that was growing inexplicably quickly and seemed perfectly content with stretching the process out for as long as it could go, all while becoming more unwieldy with each passing hour.
Even the gym wasn’t enough for Sera, not when she became as wide as she was tall, and as tall as a building story, if not more; for a creature such as her, simply lifting weights no longer sufficed for the sort of growth hunger that churned away inside of her, and things very quickly spiralled out of control as soon as she decided that the establishment wasn’t worth her patronage. Instead, the draolf spent most of her time trying to find things to lift, things that would pose some degree of challenge for her and her new body; this had the predictable side-effect of only worsening her muscle build-up, as each new object that became the focus of her attention only added to her bulging frame. Sera’s biceps alone were already the size of a small car each, her legs thicker than tree trunks and her back and neck so bulked up that her head was practically encased in a shell of raw muscle mass, giving her the appearance of something that some would call grotesque, and others would cream their pants at the mere sight of. For the house’s resident couple, each day was a struggle, as they had to actively avoid looking at Sera in order to keep their composure, Spikes especially as he was dealing with a lot of unwanted filial love creeping up his backside… sometimes literally, giving Sera’s penchant for imposing herself physically upon them.
So it was that the female draolf began to do things that could charitably be described as “extremely destructive” at their very best, figuring that, if a gym no longer catered to her needs, then the rest of the world would just have to make due; given that there was no shortage of big and heavy things lying around, Sera assumed that no one would care too much if she decided to take some of them, even if their owners happened to be directly next to them. Tim and Spikes first saw what this meant in practice when the latter’s sister went outside, found the nearest parked car, and decided to use it as a weight, lifting it effortlessly with a single hand and gaining several dozen pounds of muscle over her left arm, which were then transferred to the rest of her body… each time she lifted the damned thing. The neighbor whose vehicle that was could only stand there, staring at his ride being utterly demolished as Sera’s grip tightened and large chunks of metal were ripped out of it, until the draolf tired of using it and moved on to the next one. By the end of the day, most of the people that the couple knew had been left carless, something they both knew would eventually end up falling on their heads, leaving them groaning in anguish when the first solicitors began to show up at their doors.
This, of course, wasn’t enough for Sera, who believed herself to be much too small to stop working out just yet. Indeed, the more she admired her body in front of a large pane of glass she stole from a skyscraper, the more she came to understand that her physical form, though the literal definition of muscular perfection, was nothing if not a cocoon, the first stage of her transformation into a true goddess of that world. Much like her brother had already ascended a couple of times, thus breaking physics hard enough that growthsplosions like hers could even take place, it stood to reason that she was owed a couple of similar experiences. As such, picking up parked cars quickly progressed to stopping trucks whenever they passed by, picking them up with a whole hand, then two fingers, then finally giving up entirely and sighing whenever she saw a vehicle get close enough to her that she had to take it into consideration.
At that point, the only thing left that could even remotely pose the smallest of challenges was, well… the neighborhood itself. With similar-sized houses, she figured she could get a couple of hours of a good workout after lifting the first one, and indeed, the time it took between her first digging her heels into the earth and her fingers underneath her brother’s home, ripping it off of its foundations with a shower of debris underneath, and no longer finding any enjoyment whatsoever in repeating the stunt… was about seven or so houses in, after which her body had grown so unbelievably colossal that there was very little left around those parts that could even remotely offer the smallest of challenges. Therefore, what better place to go than the city, promising apartment blocks and delicious skyscrapers that she could progress from barely being able to compete with, to looming over and being able to crush them with a single toe?
As Sera walked away, small earthquakes caused with each footstep, Tim and Spikes crawled from underneath the rubble that used to be their house, staring at one another with worried looks. They couldn’t stop it; the draolf was too strong now, too massive, and the only way to get rid of her would involve some unsavory tactics that her brother was not willing to even think about. Thus, the only thing they could do was try and match her, hopefully enough that Spikes could try and talk her down or, failing that, keep her pinned until a more permanent solution could be found.
“You still have the serum in the lower basement?” Spikes asked, brushing plaster off his shoulders.
“Extra-strength?” the lynx asked in reply.
“Extra-strength.”
