Public Embarressment, Private Enhancement

(I thought this was a really cool premise that got unfairly abandoned, so take a chapter that hopefully helps revive it)

Barely Interesting Change! 30 Minutes!

It took a few minutes, and then surely enough, Miss Harper's Hello Kitty branded panties were revealed, too tight to hide her ass cheeks, or even hide all of her pubic hair, from the class as her skirt fell. When her skirt fell to around her ankles, one of the girls in the class burst out laughing at the sight, and soon, everyone else in class had joined in, humiliating the teacher. Josh knew then, beyond a shadow of a doubt, that the app worked.

As the teacher and the rest of the class were distracted by this moment of forced embarrassment, Josh took a look back at the app. He saw that the timer was at a measly 7 hours and 25 minutes, which was confusing until he checked the logs. While his dick size change had given him an hour, Josh had lost at least six hours to the change that made people not notice he was on his phone. Indeed, checking the app's history showed it had viewed the change around whether anyone noticed Josh's phone use as boring, and given out a massive time penalty.

Given the sheer power of the Reality Timer app, Josh decided he didn't want to find out what would happen if the app made a change automatically. With that in mind, he kept his head down until the end of class, not typing anything else until he left the classroom, and ran to the school restroom so as to check in the mirror. He was going to make three changes, all of which he hoped would give him more time, and help him understand the app better.

Josh Watkins' has a sexy body that's drool worthy for the women who see it

Josh saw his body be transformed, although not in the straightforward way he anticipated. While he gained some muscles, the main thing that happened was he got slimmer and taller. Looking more closely though, he realized his body was like a statue of an ideal man, with how his various muscles were located on his body. It was clear the app had interpreted his command in a specific way he hadn't anticipated, but unlike the genies in stories, didn't seem to be too malicious about it. Well, Josh looked a lot better than he did before, so he shrugged and checked how this had changed the timer.

Somewhat Interesting Change! One Hour!

Well, the precedent had been set with Josh's earlier physical transformation, so he went onto his next experiment.

Josh Watkins' cum is extremely tasty for women, in both flavor and texture

Josh got hard thinking about this change, imagining all the blowjobs he'd get in this new world. Checking the app, he got...

Somewhat Interesting Change! Two Hours!

Well, it was something. The combined changes got Josh Watkins up to ten hours, which felt fairly safe, but on the other hand, he could have a busy day ahead. Besides, he had learned he couldn't use boring changes to make the app safer for himself to use, and he wanted to know more about how the app worked. With that knowledge in mind, Josh Watkins typed out one final command that would test the bounds of the app

Female teachers always gain a kink for fucking male students

It would take until third period Math to find out for sure, but Josh Watkins couldn't wait to see how this change would play out. And for once the app agreed.

Interesting Change! Seven Hours!

Josh Watkins nodded, satisfied with the change as he went about his day. It was only later he found out the many unintended consequences of what he had just done...
