Well, this is a Master PC Story...

What does one do when they're handed the keys to reality itself?

What does one do when a magical computer program just falls into your lap without explanation?

What does one do when they find out that they can change their life, as well as the lives of everyone on the planet, with a few simple keystrokes?

Well, David didn't really know, so he went out onto his balcony and lit up a cigarette to think about it.

As soon as he had sat down and turned it on a mere ten minutes ago, the boot-up was different from the hundreds of other times his computer was brought back to life.

The screen was black still black after hitting the power button, but then became filled with countless little twinkling dots of light. The lights seemed to be moving past the camera, picking up speed until the screen was showing almost nothing but a beautiful barrage of colorful static. Eventually, their speed slowed and came to a sudden stop. It was then that David realized that the twinkling lights weren't moving, it was his screen, or whatever sort of camera device that was displaying that insanely detailed view for him. Right in the center of the screen, showed his own planet, Earth.

David wondered to himself what he was looking at in that moment. His computer was off before, not idling, so there was no way that he'd left YouTube on and this was some really cool space documentary, and it definitely wasn't any game that he owned. There was no way that this was an actual video feed from space, right?

Right?

Before he could formulate another hypothesis, the screen moved once again.

The image feed descended, slowly accelerating and quickly decelerating until it was over the dark skies of his snow-covered city. More specifically, right over his apartment complex. Then, it went further, passing through the roof and soon the ceiling of his room.

Showing every detail of his room in real time, along with himself, David and his expression of terror turned to face the corner of the room that the feed should be coming from.

With wide eyes, a pounding heart, and a powerful erection throbbing between his slender thighs, David slowly turned back to the screen.

And just as expected, David saw the same message only told in fictional erotica stories on the internet, one that he was all too familiar with.

“Welcome to Master PC's Command Center…”
“The Master allows you to become a virtual god to the people around you.”
“You now possess the power to bend their reality to your specifications.”
“You are the Master's Representative.”

The words scrolled across the screen in glassy, translucent green letters in one of the oldest computer fonts David had ever seen, and as soon as they passed, numerous borders and tabs appeared around the feed on the screen, along with a large black rectangular box at the bottom that was labeled "Command Center".

"User identified." Said a few more translucent words that appeared in the center of the screen for a brief period. "Hello, David."

Without a hand on his pent-up cock, David came on the spot, drenching the carpet below the desk with a record amount of spunk.

And now, he was outside in the cold with only a pair of loose shorts on his body.

He hoped that the combination of freezing-cold air mixed with the refreshing drags of a cigarette would sober him up a bit.

After all, this was all an intense dream, David thought to himself as he began to lose sensation in his snow-covered feet.

There was absolutely no way that Master PC was real. He'd read the old "Selfcest" story in the past, along with many others that revolved around the fabled program, but the introduction to that one in particular was all-too-similar to his own, which obviously meant that he went to bed without jacking off and was now having an edging-induced fever dream, one involving parts from a scene in an erotic story that his **** mind was recreating in order to bring him to orgasm.

He didn't know why his mind couldn't have just conjured up a pair of tits floating in a void. That would've worked just as well, really. But no, he had to imagine something as amazing as a computer program that could do virtually anything to, well, anything.

David sighed.

Well, he wasn't waking up, and his numb feet began to hurt from the icy bite of snow, so David decided to just go back inside and roll with whatever his dream had in store for him.

David stopped in place when he reached the center of his living room.

He stood there, glanced down at his feet, blinked a few times, and then gave himself a hard slap to the face.

He felt that.

He wasn't waking up.

Which likely meant...

David scrambled, and in a flash he was bottomless back in front of his PC, his mind spinning with a hurricane of thoughts.

"It... This can't be real."

David went straight to the Command Center and typed in the following prompt as a definitive test:

[David Cross has a three-foot-long horsecock.]

He glanced down to the erection between his legs and swallowed hard, then hit the Enter key.

In a sudden explosion of growth, David watched his cock almost instantly transform into what he was imagining. His pale member became a deep dark black color, it became both three times as long and three times as thick, the head of his cock flared out and flattened, and a thick bulging ring appeared in the center of his new cock's shaft. Not only that, but his balls inflated to the size of softballs, each of them pushing his thighs outward as they twitched in the very tight sack holding them together.

It was safe to say that the sensations following his key-press were real enough. It was as if a powerful vibration shook through every inch of his groin, as if it had been struck by lightning, but without any pain following. His heart pounded and pounded within his chest until that's all he was able to hear. The dull tension of aching pleasure coming from his new horsecock was unreal, and he began squirming around in his gray gaming chair as his head became as light as a balloon while his massive meat desperately demanded to be touched.

In a daze, he reached forward to do just that, but before contact was made, David blacked out.
