Fuck it, Jack wants to keep pushing this, makin...

Jack wasn’t even thinking anymore. His girlfriend now surpassed all but his most extreme fantasies, so huge that it felt like her mass next to him was tugging on him like a black hole, like she was so big she had her own gravity.

And he was still holding the button, which he was starting to believe could not only make the impossible happen, but had no limits of any kind. What could he do with that power?

The thought of the concept of that much power turned him on even more and broke whatever restraint had been lurking at the back of his mind. He could think of nothing now except MORE.

What if Brit and Hannah were both somehow even MORE inconceivably responsive to working out, and Hannah was in a completely different league than Brit?

Jack felt his dick blow another huge load as the universe blinked and he found himself back at his compute again.

His phone buzzed. He slid the button into his pocket and picked his phone up off the desk.

Hannah had texted: "Hey babe!Brit decided to come back with me for a movie night? You in?"

"Sure. Sounds fun." he responded, his dick already hard from the memory of what he had already experienced the past several iterations of this evening.

"Great! I just grabbed The Avengers on Blu-Ray. Such a great movie” she replied.

“I'm going to shower first. You mind coming down here to keep Brit company until I get out?"Hannah followed up, with a laughing emoji.

“Sure” he texted back, wondering what she meant by “down here”. Their apartment was on the first floor anyway…or was it? No, it WAS on the first floor, but it hadn’t always been there. He had memories of it being the third floor, but now suddenly he simultaneously knew it was the ground floor. And he knew why.

He went out into the hall and opened the front door to the building. Brit was there, now wearing tiny strips of fabric that at one point had been a sports bra and shorts, but were now more like strings, stretched to their absolute limit. She was MASSIVE. Obviously much larger than Hannah had been last time, even without Hannah there to compare. He figured he must have been staring, because Brit broke the silence.

"Don't worry," she said with a chuckle "I showered at the gym."

He just gave a nervous chuckle back.

The eight-pack that he had been marveling at before was ow entirely uncountable. Just a (surprisingly narrow, given the rest of her) wall of cubes and ridges. Her legs, which before had muscle beyond that of even professional female bodybuilders were now beyond any tree trunks except redwoods. He doubted even one of her thighs could fit through his apartment door, hence why he had to come down. Her golden hair, which she normally let flow, was pulled up into a ponytail that had to travel upwards before disappearing through a gap between her traps that reached several inches above her head. Her shoulders were so colossal they made even her titanic hips look narrow. He still hadn't spoken, left slack jawed by her bulk, so Brit continued.

"I know I've said it before, but I'm glad Hannah asked me about the gym. It's funny that she assumed I got my body from working out when really it was all from a little cheerleading and some fad diets."

Her mention of Hannah’s name jolted Jack out of his stupor. Brit was so big he had forgotten he had still imagined her the smaller of the two. If Brit was this huge, what did Hannah look like now? And where was she?

"I've made some great progress these past few months," Brit said with a pause while demonstrably tensing her muscles and melting Jack's brain some more. "But your girl has some kind of weightlifting omnipotence."

This new body still only took a few months?

Jack’s phone buzzed with another message from Hannah: “You guys coming?”

Brit saw him check his phone and connected the dots. “Speaking of which, let’s go see your girl” she said as she turned and started walking around the corner of the building. Their apartment building was small and stood on a corner. Brit led him down the sidewalk next to the building, her shoulders taking up the entire width of it, her gargantuan (and all-but-bare) butt cheeks rising and falling, flexing and unflexing in the single sexiest thing Jack had ever seen. They came around the corner to the vacant lot behind their building.

Before him stood his girlfriend, with the same cute face, perhaps even cuter with bright green eyes and long, healthy black hair. Everything else was different. Her wet raven locks had been cut into a short bob to accommodate traps that now ended several FEET above her head. Framed by shoulders that defied comprehension, appearing to be nearly the width of their entire building! It seemed the button had finally altered her frame as it was blown up with too much muscle to accommodate as-was, even accounting for the fact that she looked to be at least 2 feet taller than Brit. Her towel was gone, even the “limitless” button giving up on covering her enormity and instead having her air dry after whatever kind of outdoor shower she had rigged up in what Jack was realizing was her new living space, her body being obviously too big for any apartment, not just theirs. The vast muscles of her naked legs stretched so far from her frame, Jack was pretty sure, even relaxed, he would be able to lie on top of her quads like a bed with plenty of room to spare. Even her calves looked too big for him to wrap his arms around!

On cue, Brit broke the silence again. "Yep. I was just talking about how you've been killing it at the gym."

"It really was a good day wasn't it," Hannah responded. "I absolutely love arm day."

With that, she raised her right into perfect bicep flex. Years of looking at them online had taught her how to do it just right - even when the bicep in question swelled so enormously that it peaked above not only above her head (and traps) entirely, but just cleared the bottom of the third floor window that had been theirs in another timeline.

"Damn, girl! And to think, less than three months ago you were as thin as a twig."

"Yep. I have to say I'm proud of myself. You'll have to work very hard if you want to keep up," Hannah joked with a wink.

"Let me say, I think I still have you, girl." Brit said in an obviously sarcastic manner, knowing how ludicrous it was to suggest such a thing, even with her own “too big for indoors” mass.

Brit walked around Jack and threw up a rear flex with her right arm next to Hannah's still flexed bicep. Jack came immediately upon realizing his girlfriend's bicep was so enormous, that he couldn’t tell if Brit’s entire body could match it in size.

"Not even close, girl! We'll see if you can catch up with those." With that, Hannah dropped her flex and smacked Brit square on her kitchen table sized glutes again, bringing them to Jack's attention with a boom that sounded like artillery. Brit's mammoth ass didn't even move the slightest bit from Hannah's smack. She was still a titan in her own right.

"Alright, let’s start the movie before loverboy passes out from coming.” Brit inserted the disc and turned on the projector that shone the movie onto the side of a neighboring building. There was no couch, just a massive piece of fabric for Hannah to sit on, as her bulk would obviously crush any attempt at furniture. She sat, legs splayed due to the sheer enormity of her thighs. Brit climbed up on her left thigh and Hannah patted the other with a shockingly dainty hand that emerged from a forearm with roughly the size and muscle definition of a fighting bull. Jack scrambled up and perched not just on her thigh, but with his legs arching over just ONE ridge of her unearthly quads like a horse. He leaned back into the only soft part of Hannah left - her massive right tit, which was easily larger than his entire body. It was a totally unique contrast - the thigh below him that felt harder than diamond, and the enormous beanbag softness of her breast wrapping partially around him from behind, cradling him like the world’s sexiest cloud.

He could feel her massively powerful heart beating through both her breast and the massive thigh between his legs. It was strong enough to move him slightly, enough for his dick to rub as he nutted again, his pants quickly becoming soaked. He looked up at Hannah, embarrassed, but her smile made it clear this was just what happened when he was around her- unavoidable and by now, routine.

She giggled, causing her thighs to tense only slightly, but enough to heave Jack up and down at least foot. She immediately noticed this and intentionally flexed her super-powerful thigh, spreading his legs wider and bouncing him at least 3 feet higher, causing him to shoot an even bigger load - and his dick didn't even soften, remaining rock hard just by being in contact with her, his girlfriend acting as a natural aphrodisiac.

Hannah stopped to give him a bit of recovery time, but even at rest he could feel her individual muscle fibers twitching and multiplying beneath him, pumping her already god-shaming muscles even more vast. He recollected his sanity enough to realize Brit was up to something atop Hannah’s other thigh. He turned and saw her riding it like a mechanical bull as Hannah flexed each individual cord of muscle, rubbing Brit’s pussy from every direction and sending her back & forth and up & down. Brit moaned deeply, her left hand gripping one of Hannah’s striations as the right groped her own yoga ball sized tit. She threw her head back in ecstasy, orgasming just as Jack lost consciousness.
When he came to…
