An App for That

[Proteus]

I thought I would try my hand at starting a continuous story that anyone can add to. My only major request is no underage sex. Also, the device itself only modifies the subject?s body, not their clothes or their mind (aside from maybe some emotional states?you might be able to make someone horny, but you can?t force them to fall in love with you). Each use also drains about 20% of the battery, so there are limits to how much you can do with it.

It was Sunday night, and Scott Thompson lay on his bed, playing with his new smartphone. He had just received it a few days before for his eighteenth birthday. While he retained the same wish he had every weekend?that he had somebody special to spend it with?he was thoroughly enjoying himself, fiddling with his new gadget.

He had downloaded and run dozens of apps in the past few days, and now he was testing out a third-party web browser. It had an ?incognito mode? that hid all activity from the history, and Scott knew just the site to test it out on. He frequented a certain male muscle growth forum?one thing he desired more than a boyfriend was muscle. Huge, hard, powerful muscle. He successfully logged into the site and navigated to the story section, holding his screen sideways so that it was shaped like a sharp, four inch computer screen. A thread caught his eye and he clicked.

Unfortunately, the only post was a spambot that had cleverly selected ?Man grows MUSCLES beyond dreams? as a title from a few randomized keywords.

Well, that?s a bust, thought Scott. He went to scroll the page to see if there was any way to report the post, and in the process, his finger strayed just a second too long on the spambot?s fraudulent link.

?DOWNLOADING?? read a dialogue box that popped up in the center of the screen.

?Shit,? Scott said under his breath, realizing that he had accidentally tapped on the link.

This was great. Just great. His new phone, a device so useful and cool that it vied with his laptop for his prized possession, was screwed. Some sort of malicious code was embedding itself deep within the operating system, and there was nothing he could do about it! He tapped the back button to no avail and futilely held the power button, but all that happened was the dots in the ellipses in the dialogue box blinked one by one. At last, Scott had an idea. He flipped over his phone, pried off the back cover, and removed the battery. The screen instantly went blank and Scott breathed a sigh of relief. Had he averted catastrophe?

Cautiously, he replaced the battery and turned his phone back on. After the boot animation whirred away, he was greeted by the app drawer. Thankfully, everything appeared to be running smoothly. He reopened the browser and checked the history and downloads?nothing. At least the incognito mode had worked. He swiped through the app drawer again out of habit when he noticed something.

A single icon, nestled amongst the others in the grid, highlighted with a yellowish-orange glow. MetaMaster, it was labeled. The icon was a stylized strand of DNA.

At first, Scott?s heart sank. The link had installed something, after all. He stared for a moment, then, against his better instincts, tapped the double helix.

The screen turned black and a gray circle spun, indicating that the app was loading. After about a minute, during which Scott was sure something terrible had happened to freeze the phone, the spinning circle turned yellowish-orange and dissipated into animated globules that were flung away by the simulated centrifugal force. Scott was faced with a simple menu composed of dark blues and grays. ?MetaMaster? was written in bright orange and yellow at the top. He had three options to choose from, each in white lettering.
?New Subject?
?Settings?
?Quit?

What the hell? he though, he might as well see what this program did. He tapped ?New Subject? and the button highlighted the same yellowish-orange color that the icon had glowed. The screen went blank again, then Scott?s bedspread came into focus. The app had turned on the camera and displayed a few buttons along with plus-shaped crosshairs in the center of the screen. After a moment, Scoot spotted the ?switch camera? symbol and pressed it; his bed was replaced by his own face. The crosshairs turned bright green and he hit the button that had some version of the ?take picture? symbol on it.

?Ah??? he gasped as his skin prickled and he got goose bumps. It felt like he was covered in static, like he had just rubbed his hair against a balloon.

The screen now displayed a plethora of text boxes with various numbers in them. A cursor blinked in one labeled ?height? that read ?70 in.? He recognized his own height of 5?10? and saw another label that read ?weight? followed by ?148 lb.? That was his weight as well. A quick glance at other readings confirmed that the app had correctly taken his measurements, including, embarrassingly enough, his penis at just under six inches.

?This is a little creepy,? he said aloud. His curiosity got the better of him, and he decided to play around a bit. He upped the weight to ?160 lb? and noticed that the ?body fat? section had a box with a picture of a padlock on it that was unchecked. After he entered his imagined weight, the body fat went from ?21.2%? to ?20%.? A number of other categories had the padlock checkbox, including an unchecked one that linked the height and weight measurements. Scott thought about it and guessed that these locked in the measurements or (in the case of height and weight) kept the same ratio. It was all a bit much to take in at once, so he did not mess around with any more settings.

He scrolled to the bottom of the list of measurements and found a button that said ?Execute.? Scott smiled, imagining himself with twelve more pounds of muscle and pressed the button.

Immediately the phone?s flash strobed. A jolt shot through his body, like he had been shocked by static. Then it ended, and everything felt normal again. The phone displayed the spinning gray circle, indicating it was in the process of doing something. And then, Scott felt it.

His body was changing. It was almost imperceptible at first, but then it accelerated. All of the sudden his muscles began to swell!

In terms of where this story's going, I'm thinking Scott experiments on himself that night, then goes to school the next day--and that's where the real fun begins. Any other ideas?

maybe a friend/rival/teacher at school downloads the app as well?

That could definitely provide an antagonist and some conflict.

Part 2

There was no pain, no pleasure, just the feeling of fatigue. It was as though he had just worked out strenuously. Other than that, Scott would not have noticed the growth if it was not for his tightening shirt.

Impossible! he thought. He looked over at the mirror on his closet door, and sure enough, he was growing. The growth lasted for five minutes, then subsided.

Scott lifted his tight T-shirt to see a set of ripped abs were his unremarkable stomach used to be. He flexed in the mirror, immediately getting hard. Then his mind jumped straight to all of the possibilities now that he knew what his phone was capable of doing. His head spun as realized that he could fulfill strong desires he had only dreamed of for years.

He turned his attention back to the phone and scoured the app for every detail—he had to know exactly what he was doing with something this powerful. He browsed the settings and found a timer set to five minutes. Scott was eager to pack on some pounds quickly so he changed the time to 30 seconds.

Next, he fiddled with his stats, fingers shaking. He actually had to enter some of the numbers twice because he hit the wrong keys in his excitement. He reset his body fat percentage to 7% and made his new height 6’6”. The most thrilling part, however, was the weight setting.
I need to be bigger than the biggest super-heavyweight bodybuilder, he thought greedily. 400 pounds should do it!

When he was all set, Scott locked his door and stood before the mirror. His reflection had already changed to that of a teenager that spent some time in the gym, but soon it would become unreal. Briefly, he thought to remove his clothes, but decided against it, smiling. He hit “Execute” and with a flash from the phone, the strenuous sensation returned.

All of the sudden, Scott’s clothes went from slightly-tighter fitting to constricting. His legs began to bulk up and fill out the legs of his jeans, his ass immediately firming up and filling the seat. Scott’s chest pressed out in front of him, making straining lines across the front of his shirt. His lats and his back thickened, pulling the rest of the shirt snuggly against his body. His sleeves were soon full of growing biceps and triceps and veins rose on his meaty forearms.

Scott looked like a well-developed teen bodybuilder when his clothes began to rip. A tear formed vertically on his chest as his pecs continued exploding outward with mass. His sleeves, which had ridden up to his spherical delts, tore at their seems as he struck a double bicep pose and the extra tight shirt rode up, exposing a large, blocky six-pack. Scott’s jeans were extremely uncomfortable at this point, bunching up and pressing painfully even at his calves which were partially showing as he grew taller. Grinning, he squatted down. Pop! went the seams on the side of his jeans, blowing open like a boiler with too much pressure in it.

Scott grabbed the growing hole in the center of his T-shirt and tore the rest of the garment away, tossing it to the side. With a little bit of effort supplied by his bulging arms, he ripped and peeled away pieces of his jeans until only his boxers remained. By now they looked like boxer briefs and were riding up his massive thighs and solid glutes. Scott flexed his legs, now wider than his waist used to be, and the boxers split open at the bottom. Hooking his thumbs under the elastic, he destroyed the tattered trunks and let them drop to the ground like rags. Now he was fully exposed, and his dick was harder than it had ever been before, pointing up to his sculpted abs. Scott had stopped growing by this point, but he was still taking in his new 250 pounds of flesh. He shrugged his shoulders and his traps went up to his ears, for crying out loud! He was bigger than every bodybuilder in the world now!

He immediately went for the most muscular pose, watching the striations separate different parts of his mammoth pecs, his nipples forced to point down by the abundance of the new meat. His upper arms were bloated and overstuffed, with a single, thick vein running down each one (in addition to several smaller ones), feeding his new muscles. Putting his hands behind his head, he crunched his abs and was blown away by the sheer size of them. His obliques and intercostals rose as bumps before his back widened his profile so much that when he relaxed his body, his arms were pushed out at a 45 degree angle. His stance had widened significantly as well.

Scott could come on the spot, but he held back. Though his cock was throbbing, pleading for release, he had bigger plans in mind for it.
With the same glee and anticipation as before, the pumped-up 18 year old entered new dimensions for his member. Nine inches… now that would be fantastic.

But you know what would be incredible…

When he executed the command this time, he felt pleasure tingling along his cock. His eyes widened (even more than they had before) as it stretched and broadened, like a long balloon being filled with water. It felt amazing as the girth increased, the head expanded, and his balls swelled proportionately. After the half minute had passed, his cock was a foot long and no longer pointing straight up all the time—it was weighed down significantly, rising the whole way only when Scott intentionally flexed it.

The muscular young man was ecstatic. He went to town on himself immediately, using both newly enlarged hands to wrap around the thick shaft. The sensation was more intense than coming had been with his old cock, each stoke sending waves of pleasure through him. His engorged cock soon expelled precum, lubricating itself. He was getting closer and closer to the edge, occasionally looking up to the mirror to watch his whole body flex and bulge in time. When he climaxed, he was overwhelmed by the feeling of so much more of him devoted to feeling pleasure. He shot cum on the mirror, not in short bursts, but in streams. Ropes of semen ran across the floor from the door. Scott heaved his mighty body, exhaling as he came down from the biggest high of his life.

He spent the next half hour exploring his new body, running his hands sensuously across every mountain and canyon formed by his hot muscles.
Scott was roused from his state of euphoria by a buzzing noise. His phone was alerting him to something. He turned on the screen and saw that the battery was almost dead. The magical app was quite the drain on the device. He would have to be careful so that he did not end up stuck as a giant while his phone charged, unable to change back when his parents were around. After plugging in the smartphone, he navigated to the stats part of the app and found the option to revert to previous states. He tapped the button a few times and his normal, 148 pound readings showed up. Once his phone was at 50%, he reluctantly returned to his comparatively shrimpy, out of shape body. The phone’s battery was now at 31%. Scott did the math in his head and determined that he could only transform five times on a single charge.

Before he went to sleep, he went over what he wanted to look like for school tomorrow. He figured that he could add about five pounds of muscle and lower his fat percentage a little and no one would really notice. People did not pay much attention to him at school, so he could probably get away with more, but he decided to play it safe. For the first day, at least.

Then Scott’s brain lit up as he realized something. It would be a waste to limit the app to changing only himself. High school offered the perfect targets for him to have some fun with…

I don't have any specific places in mind for the story to go, so even you don't plan on writing a part yourself, feel free to give suggestions.

[vga518]

I have a few suggestions:
1) Scott can give his friend a boost in confidence with a little change
2) Give a Jerk/ Jock his comeuppance (doesnt have to be permanent)
3) Help his favorite teacher get the respect he deserves by creating a smart yet sexy teach
4) He could do buck crazy and test the limits of the app.... At some point and not necessarily on himself.
5) Scott could create an "Incredible Hulk" and a "Caveman" DURING one of his classes.
Those are just some I'm sure I could come up with others.

I'd love to see a storyline of the kind bad guy/jock who bullied him for years steals his phone and becomes a muscle monster.
