It didn't take long for the unicorn girl to work out what had caused her transformation, but doing something about it was another story. Her hooves weren't really all that well suited for typing, her tail made sitting in a chair a little awkward, and quite frankly there were enough other little adjustments to make with all these changes that trying to dig out a chapter on a story site she'd written something like a year ago wasn't exactly her highest priority.
Eventually though, she found the time to dig through the archives and... there it was. Apparently all these changes were thanks to some guy called Lost getting bored and maybe a little horny one day. She sighed and looked at the new protrusion on her forehead that had been constantly distracting her and getting caught on door frames these last couple months.
Flora read over the latest entry a few times, pondering what to do. This guy didn't seem all that vindictive. He probably didn't believe this sort of thing really worked, and the fact that he hadn't turned her into some sort of crazed sex maniac or made this painful was... more than she'd expect form most of these posters. So no need to be vindictive, but she definitely had to do something to show this guy this wasn't anything to joke about.
Lost, meanwhile, was in the middle of taking a shower, when he noticed his elbow bumping into the wall. This was shortly followed by his shoulder smacking into the shower curtain rod, and the shower head dropping down, relative to his eyes.He was growing, quite suddenly and swiftly, not just gaining height, but gaining muscle. It was hard to tell, but he felt like a bodybuilder, and he seemed to be growing a wild flowing mane of dirty brown hair as well. Quite literally a mane, in fact. Along with a golden fuzz spreading quickly across his skin.
Stumbling out of the shower to look in the mirror, he saw further changes happening at quite a rapid face. His ears became rounder as they migrated towards the top of his head. His nose and mouth warped out to form a muzzle, as his eyes turned an almost golden brown. He almost tripped as his legs began to reshape to a digitigrade configuration, pushing his overall height up even further. There was an intense itching at the base of his spine as a tufted tail began to sprout and grow... and of course, his fingers grew much thicker, nails turning to rather sharp claws. "What the hell!?" he asked in a low growl as his face further reshaped itself, broadening his features and leaving the tip of his nose solid black. His teeth reconfigured themselves to the fangs of a carnivore, which was going to make anything with a "th" harder to say, he was sure, and a sudden craving for the rarest meat he could find struck him as he staggered out of the bathroom, still a little unsure how to walk, and large enough to have a hard time fitting through the door. He figured he was just over 8 feet tall now, and built like some kind of weightlifter.
While he thawed out a steak so he could hopefully think straight, he paced around, slowly getting used to how his new tail helped him balance, and reaching into his closet to confirm that none of his clothes had changed along with him. He didn't feel any particular shame walking around in the nude, but as he tried in vain to at least get a pair of shorts on, he couldn't help but notice he was now endowed with a pretty damn sizable pair of balls, and some sort of sheath which would still likely draw some attention, even if the rest of the world proved not to have an issue with massive nude lion men strutting around.
His immediate instinct was to head to CYOC and confirm that he really had been changed like this after adding to a story, but he had so much pent up energy all of the sudden. His home was feeling entirely too cramped as well, so throwing aside any sense of caution or modesty, he just headed out the door, and jogged three laps around the block before coming back to devour his bloody red steak and lie down for a bit before planning his next move.
Flora was just about done typing, nodding with some smug satisfaction that she'd gotten the seriousness of all this across, without sticking this Lost guy with hooves or quite so much of a sudden identity crisis. She signed her post as Wert to keep it with the rest of her entries on the site, and sat back to see if things would escalate from here. At least until the pressure on her tail grew too uncomfortable. She'd definitely have to make some changes, furniture wise.
