A growth spurt!

As expected, the tingling sensation filled his groin for a moment. Once the feeling subsided, he pulled down his pants to see "Little Josh" is not as little anymore! It is not a huge improvement, but he is still relaxed anyway. What is it at full mast? Time to find out! For science.

Josh checked and double checked to ensure his blinds were closed, curtains were shut, and door was locked before browsing the internet on his fancy new smart phone. Finding some porn with big dicks, he watched with interest as his member grew to new heights! He was pretty average before, but now is a lot more! Or at least the old average. What is the new one now, anyway?

Our soon-to-be hero fondled himself for a few moments, impressed at his own size. As a newfound sense of pride washed over him, Josh pleasured himself to the porn, then cleaned up and unsecured the fort. Now what to do next??

This app is great! Although it does feel like holding a book of cheat codes. As every game knows, too many cheat codes, especially early in the game, makes everything too easy and not fun. This is more of a... head start. Ideas swirled like a hurricane in his mind, but enacting them all was not a smart idea. A select few ideas were good ones though, so it was back to the app!

"People are inherently attracted to larger genitals, but each person retains their own unique preferences and fetishes."

"The human body can handle large objects inserted into their sexual organs. Pleasure is still gained, but the tolerance is very high before receiving pain from size."

That should balance out the new penis scale. Wouldn't want to have a big dick without a pussy to handle it, right? Now to get rid of some annoyances:

"Diseases and infections are not transmitted sexually."

"It is more accepted to have a sexual affair with a partner of greater genital size. This level of acceptance is still determined by each individual's preferences."

"Typically, the smaller the genitals, the more submissive the human, and the larger the genitals, the more dominant the human. Females are typically more attracted to larger genitals. Each individual possesses their own unique preferences, and may contradict this."

One more interesting one for extra flavor to this new reality:

"While very rare, it is possible for a human to be born as a true hermaphrodite. These individuals have all the qualities of a female, but with the addition of fully functioning penis and testicles as well."

There! Some new rules to make the world a bit more... fun. And hopefully a little balanced. The meek have inherited the earth!
