Before anything else, Greg quickly changed his own stats to match Jason's. This was fanfic, right? As much as the thought embarrassed him, he knew that in his perfect world his dick would be just as pitiful as the college twink's.
But what else could he write? He frowned, closing his eyes and trying to imagine his perfect fantasy. This Jason kid didn't think big enough, he mused, just accurately reporting how big the human dick was and how tiny he was compared to it. If Greg was writing the rules, the average size wouldn't just be "7 to 10 inches." For a moment he considered making everyone in his fantasy as tiny as Jason, but immediately dismissed the thought. Half the fun came from the embarrassment and humiliation, being taken and used by bigger men...should everyone else be even bigger?
Finally, he hit on it. In his fantasy reality, he would get to share the fun.
He crossed out the entire line about average penis size — who cares about Jason's pervy diary entries, anyway — and wrote something new.
"Average penis sizes for 75% of men:
Erect: 10-15 inches
Flaccid: 7-9 inches
Penis sizes for the remaining 25% of men:
Erect: 1 inch
Flaccid: ½ inch"
He didn't bother with thickness — this was just his fantasy after all, not some high school lab report. Instead, he added a bit of prose. The Jason kid had been far too statistical with his fantasies. Greg wanted to spice things up, but he decided on a whim to stick with the science-textbook-dry descriptions.
He wrote:
"Small-dicked men are all both embarrassed and aroused by how small they are in comparison to other men, while large-dicked men instinctually want to humiliate or dominate small-dicked ones. Even straight men will feel comfortable using a small-dicked man sexually without thinking it's gay, and straight small-dicks will fight against their inherent submissiveness to large-dicks but ultimately give in."
He groaned softly at the fantasy, imagining how Larry would treat him and Jason in the world he'd made up. Fuck, maybe this Jason kid had the right idea. Writing down his ideal kinky world had gotten him rock hard.
Quickly, he stuffed the book into his bag, and strode off towards the nearest bus stop to catch a ride home. He needed to jack off, and soon. He was in such a hurry that he didn't notice as his new words flowed into the pages of the book, and, slowly, became true.
