Himiko's New Act

It wasn't too farfetched for Shuichi to think that his new powers could do much more than he had done so far. If there was no limit, as he believed, then he could change clothes, personalities, Ultimate talents, genders, and so much more. And he was enthralled by all these possibilities, all these different ways to have his fun, without the chance for anyone to find out. He didn't particularly want to use this power on his friends, but they immediately adapt to it and don't mind. Besides, with Monokuma being behind them, the earrings would probably stop working the second they get off campus. So, Shuichi went out to look for someone else around Hope's Peak to change.

He soon found the next classmate, as Himiko was walking towards him in the hall, waving to Angie behind her. Perfect. Shuichi goes up to her. "Hey Himiko. Any chance I could talk for a bit?"

"Nyeh? Sure, I guess. What is it, Shuichi?"

"I'm just checking something; you're normally the Ultimate Slut, right?"

In front of his eyes, Himiko's uniform instantly changes. While the color of it stayed the same, black and red, it abandoned the mage shtick for something befitting an Ultimate Slut. No more headgear, instead replaced by a collar with condoms stuffed under it. A relatively normal school shirt turns into a tiny little crop top that looks to be struggling to fit properly with even Himiko, one of the smallest students in the school. Her skirt basically gets cut, 90% of the length evaporating into thin air, showing the complete lack of panties off. The last article of clothing that was changed was her shoes, turning into high heels you'd expect a model to wear, giving her an extra foot at least (not that it made her even average height). "I mean, yeah. That's what I've been since I got to this academy. Did you think I changed Ultimates or something?"

"No, sorry, it was a dumb question." Shuichi was kind of... disappointed. Her body didn't change, even when both of her assets could've used it. Then he got an idea. "I heard that you normally showcase your Ultimate talent by giving anal, due to you normally having a very large ass. Is that true?"

"Yeah, I guess. Why are you using 'normally' so much? It's not like my butt changes sizes or anything." Again, in the blink of an eye, Himiko changes, this time all the change centering around her ass, as you could've guessed. It bubbled out a very large amount, being impossible to miss even if Himiko did have a normal size skirt, but with her current microskirt, you'd need to be blind to not see it. It had to be even bigger than what Tsumugi got, rippling from even the slightest ove movements.

"Again sorry, I've been trying to expand my vocabulary." Now THAT was what he was talking about! He immediately went around behind her, pulling out his dick and sticking it in her ass, and beginning to pump. He slaps her ass hard, ripples bouncing away like it's a body of water.

"It's fine, nyeh. And hurry up back there, Tenko and I are supposed to meet up." She was really nonchalant about this, despite the pleasure and possibly pain that was stemming from this. Though, if she was the Ultimate Slut, she had probably been fucked a lot harder by a lot more people.

"Okay, got it." Shuichi sped up a large amount, railing Himiko's ass like he never railed anything before (which he hadn't, but still). It wasn't too long before he erupted, spewing his seed all inside her ass. Then, after he pulled out, she pulled out a tissue stored under her shirt and wiped up the mess, before nodding to Shuichi and walking off. Shuichi, now somewhat exhausted, went off to look for the next person.

Current effects:

Maki: Does not wear skirts. Flashes anyone she talks with.

Tsumugi: Has the body of Junko Enoshima. Has tits and ass double the size of Miu's.

Himiko: Is the Ultimate Slut. Has a very large ass and displays her talent by receiving anal.

Feel free to share recommendations for future characters, changes, or both. I'm already running out of good ideas and could use them. If you want proof I'm out of ideas, look at the time discrepancy between Tsumugi's Advanced "Cosplaying" and this chapter.
