Alex was inspired by all this sexualized wrestling. After making some quick edits to ensure he could always access and use the book without either him or the book getting damaged, he decided to make it so that people would always consent to sex. Public sex, nudity, stripping, and masturbation were fine...and so was locker room trespassing. There would still be some initial awkwardness for prude people (to preserve the fun of despoiling them), but Alex could do whatever he wanted with his horniness...and so could other people.
Alex decided to let people solve their own problems with STDs, injury, and specific fetishes, by making it so that sexual actions could transform people according to their wills, the more sex the better the resulting miracles. Healing, supplies, and even superpowers could be made by (usually sexual and body-emission) magic. People could now think clearly and sexually pleasure themselves (and thus change) with non-physical 'extra mind'. This works even if they turned into something that shouldn't be able to (like if their bodies become inanimate, sexless, dumb, and/or so horny they can't think straight). Several edits later, it was so. The overall tendency of this was set to be more gay over time, until the fully female form was basically just a collection of anatomical, stylistic, and/or historical fetishes. Sure, some people would transform back into themselves or to a new baseline when they lost interest in whatever experience, but it'd spice up what was around to bang without comment.
The world altered subtly. Furries, mythical beings, kinky bodies, and transforming between many different shapes and sizes were now recognized parts of world history. Very little seemed to change in the locker room's structure, though Alex no longer felt the need to at least vaguely hide and a few of the older men from the crowd had filtered in for post-match discussion. Alex knew the victors were getting a lot more attention in a different section. Coach was now a light green orc with short tusks and surprisingly thick black body hair (rarer nowadays, but not unheard of), naked but for a blue baseball cap with white trim. The three wrestler boys had bigger butts, probably from all the being on bottom of now openly-sexualized wrestling. Coach looked at a clipboard to adjust meeting plans and grunted, masturbating with his free hand to the idea of the boys doing better.
Alex remembered that with the wrestling being a gay sport already, it now had much more intense hardcore sex leagues. He revised the rules about Danny, Carlo, and Billy out of pity, so that they'd no longer always lose and they'd eventually catch onto the whole gay sport thing...but as things were going, Coach would have a hard time about it. Rebuilding the boys' muscles through sex manually was entirely legal, but getting the best build for their weight class's view of muscle and permitted superpowers could take practice to get something they'd do best with.
Leaving the book in a properly secured locker, a naked Alex joined the trio in the showers. Shortly after, the coach arrived. Testing out his new changes to the world, Alex grabbed some cocks and hands and started a circlejerk without anyone so much as saying anything but some breathy moans. Willing all their dicks smaller and balls bigger for a few minutes, Alex was caught up in the increasing sensitivity of boners shrinking down and nuts sizing up. Cumming proved both easier and more prodigious, creating a mess washed away by the water. Alex pulled back and rubbed his junk to a bigger erect size, watching Coach do much the same.
The coach ordered "Loosen up your asses, men." to the wrestler boys, meriting the start of some self-fingering sessions and the curious glances of a few locker room visitors. "I'm going to fuck some more muscle into you."
Alex grinned evilly. This was working out great.
