Leon pushed open the door and saw Jake messing with his laptop. "Hey, what's wrong? You look panicked." Jake quickly closed his laptop and greeted Leon. "Nah, man. I'm fine. Just watching Time Raiders end on a cliff hanger got me a little tense." He calmly reassured Leon. Jake was at least thankful that the alter reality options worked. Best not to have Leon freak out. Although the change Leon was getting might.
"Whatever. Listen, I got a date coming in an hour, and I figured you were heading out to eat. You mind if I get some alone time?" Jake was hesitant. He needed to confirm what Leon's change was going to be. Than Jake noticed something. Leon's head was protruding some sort of bump right in the center of his forehead. He also noticed his legs were getting thicker. Leon somehow didn't seem to notice. "... Hello? Jake?" Jake snapped back to Leon's face. "Sorry... Yeah, I'll head out in a bit. Just need to finish something on my laptop." Leon looked at him confused. "Didn't you just close... Nevermind. Just be out in an hour and I'll appreciate... Huh?"
Jake's fears were coming to realization that Leon was aware of the changes. Leon noticed his legs were getting thicker and longer. He even looked in the mirror and saw the bump emitting from his forehead. "What's happening? Is this another puberty sprout- Ung! What?" Jake and Leon noticed his legs were growing so much muscle it was starting to strain his jeans. Not long after, they burst into tatters, revealing muscular legs with white fur. "Jake... Don't... Don't look at me like that." Jake looked wide eyed at Leon's change. His legs were toned, muscular, and toped wit beautiful white fur. Jake then looked down to see his shoes and socks burst and his toes reshape. "Ugh... What now?" Leon struggling with the transformation as his tan feet slowly stated turning black and fusing his toes together. They formed into hard black hooves.
Leon felt intense pressure on his backside and collapsed to the floor. As Jake looked at his struggling roommate, he noticed a bump above his buttocks. He was growing a tail too it seemed. "Ah... Jake... I... I kinda like this... Ha... This feels good." This made Jake smile, swishing his own tail. He knew how it felt. His tail started growing long white hairs that were just as bright as the fur on his legs, growing about 4 feet. Leon's tail twitched happily. From what Jake understood, Leon was turning into some sort of horse. But what about the bump at the top of his head?
That anwser came soon enough as Leon's forehead exerted the same pressure he felt from his tail. A sharp object came pinching out from under his brown hair. A stiff, and sturdy horn grew to about 8 inches. Leon felt the horn and moaned. "My God this is weird. But it feel so good." Leon was enjoying himself too much, he didn't even notice hat his ears became pointed with white fur at the tip. Jake put most of the pieces together. Was he turning into a unicorn?
Leon started aching in his gut, as two more bumps grew from the base of his legs. Jake watched as the bumps rapidly extend with the same fur on his legs. The tips of the bumps formed into black cloven hooves just like his legs. The new growth started gaining the same muscle as his own legs, only making Jake and Leon realize he now had four legs. Now there was even more pressure in his back, as Leon's new legs started separating from his back legs. The legs spread far apart as Leon's second torso developed, and the same white fur spread all around. With one last change, Leon's black hair started to grow across his back and turned white in the process, creating a beautiful mane
It was now clear to Jake. Staring at Leon breathing heavily on the floor, he confirmed Leon was not only a unicorn, but a unicorn centaur.
