A young & lonely pervert

Mark Harris felt like a loser. He had no job, no friends, and had dropped out of college after a semester. He just wasted his days away sitting at his computer and jacking off. As he sat, wallowing in his misery, he noticed a shortcut on his desktop that hadn't been there five minutes previously.

"Master PC? The fuck is that?"

Instead of trying to delete it, Mark double clicked on the shortcut and opened Master PC

A small pop-up appeared and asked for his name, which he compiled with. A few seconds later, a large interface appeared, with what appeared to be a 3D render of him and to the left of that a large menu of sliders. Mark glanced over the labels until one caught his eye.

"Penis length? Heh, imagine if..."

Mark trailed off as he moved the slider and felt an odd but pleasant sensation in his crotch. He quickly yanked down the shorts he had been wearing, and even through his underwear he could see that his cock had grown. Mark rushed downstairs to find his Dad's toolbox and took out the tape measure, and found that his new dick was 6.4 inches long. When he returned to his computer, he saw that the number display under the slider was also 6.4 inches. Many thoughts raced through Mark's head as he sat, staring at the screen

"What else can this thing do?"
