His cock was lying soft and heavy between his legs at ten inches.
Flaccid.
Henry was speechless, and more than a little flabbergasted. What exactly had just happened? He glanced at the yellow piece of plastic still gripped in his hand, something about it was very special, something that let him make his cock get bigger.
But how bigger exactly? Henry examined his package a little closer. The penis itself appeared to have the same proportions and properties, it still was circumcised and such, and the thickness had grown in proportion to the length. The same applied for the testicles, they too had grown and now look to be just a tad bigger than tennis balls.... rather oblong tennis balls, but that was irrelevant.
Henry did some quick calculations in his head, My cock was 3.75, give or take, inches soft before and now it's ten inches, Nevermind exactly how he knew the exact dimensions of his cock by heart, Henry's just weird like that, That makes for an increase of 6.25 inches. Since a cock that's 3.75 inches isn't going to grow the same amount as a cock that is 10 inches when it gets erect, that means the difference in size between my old cock and my new one will be greater than 6.25 inches when hard, meaning that it is likely that the card did not add a specific amount of cock, but rather increased its size by a certain factor or other. Hmm, now let's see. If it went from 3.75 to 10, that's an increase of around.... 166.66%. In layman's terms, that's equivalent of doubling its size and then adding on an additional 1/3 of the new size. I was 6 inches hard before, so twice that plus one third.... If my calculations are correct, and assuming that the ratio of its size hard to its size soft remained constant, that means that my new dick SHOULD be 16 inches erect.
Henry took a moment to let that sink in.
16 motherfucking inches.
Goosebumps traveled up his arms, and he looked down at the still-soft cock. Well, he reasoned to himself, I can't exactly let my hypothesis go to waste.
Then he reached down and grabbed his new cock, feeling the new weight, and began to stroke.
The cock responded with gusto, plumping up and beginning to engorge itself with blood. With only minimal effort, Henry got it to a state of semi-erectness. He stroked the vast surface area, and found that his hands were too small to completely wrap around the width. As the cock plumped up and expanded more, he stroked even faster, focusing in on the glans and the sensitive flesh right at its borders. With one hand still stroking the still-increasing length, he reached down with the other to cup his titanic balls, feeling their weight. He could practically feel the cum sloshing around inside them, except for the fact that that was nothing like how testicles operated, as they were not just sacks filled with liquid, but rather the location of sperm production, in fact most of the liquids that make up semen are not produced in the testicles at all, but instead in other glands. Nevertheless, feeling the massive size of his new balls turned Henry on even more.
The cock was getting firm, and was very near complete erection. It gave one final throb, and was finished. Henry was now standing in his bedroom, his hand stroking the biggest, fattest, hardest fuckpole on Earth, while his other hand was cupping the most voluminous, heaviest testicles. He giggled to himself, and grabbed his ruler off his desk. Placing it up against the side of his warm cockflesh, he cursed himself, Of course it'd be too short! Placing his thumb at the end of the ruler to mark its place, he move it up to measure the final couple of inches.
He giggled once more, feeling lightheaded with glee.
The cock measured exactly 16 inches.
The penis was now calling out for attention, throbbing and pulsing, begging to be stroked. Henry was tempted, sorely tempted, but there were still mysteries yet unsolved. How exactly did the card work? If he swiped it again would his cock grow ten inches once more, or by another 166.66%? What did the other cards do, if anything at all?
His dick didn't particularly care for this line of questioning, and in a last-ditch attempt to get attention it started to cry. Large, fat drops of precum welled up at the tip, then ran down the sides, dripping onto the carpet with a dull splat. "Oh, quiet you!" Henry chided, and then immediately felt foolish for talking to his penis. The cock did have a point though, why the hell was he pondering science-y questions when he had a fat, long cock that demanded his attention?
