Mukuro - Ultra Toilet Girl (Patreon)

Dialogue written by the commissioner!

Commission for TehSuki on DA! Thank you so much for commissioning!

For context: This TF takes place in an AU of sorts where Mukuro survives the events of DR1 and becomes Komaru's partner during the events of Ultra Despair Girls. Oh, and Komaru's hacking gun has TF properties now. The dialogue used is taken straight from one of the commissioner's RPs which they asked me to use, here's the uncut version (of what's relevant to the pictures, at least lol)!

After a long journey of working through Towa City, the duo of Mukuro and Komaru finally got to the final big battle against Big Bang Monokuma. Normally Komaru wouldn’t be so nervous, but this moment was so climactic that she felt the tension hitting her all. All the toilets out in the city were destroyed, leaving her not having been able to stop and go after she left the hideout. She had to go, and bad. She’d even take one of the duck toilets right now, but there was none to be seen.

“I-I’m… really scared Mukuro… I feel scared shitless about this final boss and well…I kinda need to go…”

“You’ve been complaining about that since after we left. You really can’t just go and hide in a corner somewhere and do it?”

“A-And what if someone sees me! There are so many people out now, they’d never want me to face Big Bang Monokuma if they saw me do something like that! I’ve been looking for so long and there’s nothing… S-So… Mukuro…”

“… No way.”

“Come on, please! I have to go really bad! I-If you let me do it, I’ll let you turn me into a bed later so you can get a good amount of sleep!”

“Komaru if you turn me into a toilet, you’re going to go in me and… ugh…”

The soldier looked at Komaru who had pleading eyes that showed her true need for the bathroom. It reminded her too damn much of Makoto as Mukuro felt herself starting to waver. She didn’t want to just give in and do something so gross, but she knew Komaru was really struggling as the normal girl couldn’t stand still. Letting out an annoyed sigh, Mukuro spoke up again and decided to make a call she didn’t want to.

“Fine. If you have to go THAT bad… Just do it.”

“A-Are you sure? I feel kinda bad now…”

“You’ll just be liable in this final battle if I don’t… Just be quick, please?”

“O-Ok! I’ll do my best!”

Komaru chuckled nervously as she took the hacking gun and raised it at Mukuro. She shot her with it and the soldier found the gun begin to take effect right away. Her mouth scrunched out widely out of her control and left her instantly beginning to realize what she agreed to and that this was going to be a true mistake. She felt her ass squat down and sag into a pair of bare metal piping that dug its way into the ground. Around her began to form a few walls to help give Komaru the privacy she needed. They were formed from Mukuro’s arms that flattened out and sunk into the ground partially. The rest of Mukuro continued her transformation with her head forming into the tank and her body turning into the other parts of it like the internal structures and piping. Her anus and pussy became two separate piping plugs within the toilet. The anus was set to take in the solids down the piping while the vagina would take on liquids. What wasn’t turned into this stuff was crunched and compressed away in the plumbing. Her mouth was all of the bowl, leaving her set to be quite grossed out. This wasn’t quite such a simple transformation like the rest, as her head being the tank left it to slosh slightly and take on some slight “toilet instincts” of wanting to take in waste, much to Mukuro’s chagrin. The bowl finished off its creation as her maw stretched and elongated the rest of the way. Her face ended up being plastered onto the lid of the toilet and was the last bit of transformation as Komaru let out a sigh of relief that she’d finally finished stretching out.

“Oh thank you Mukuro! I promise to make this up to you! I won’t forget this!”

“(Y-Yeah, just hurry up…)”

Komaru entered the bathroom stall and closed the door. She reached under her skirt and pulled down her panties to around her ankles before pulling up the lid of her toilet friend. She sat down on the seat and found it a lot warmer than she’d expected it to be. It was thanks to it being Mukuro. Despite having to go super badly moments ago, Komaru found herself being a little shy about dropping off her crap as she knew it’d be going down into her friend. It took a few moments before Komaru finally was able to let out a gassy sputter and dropped off a few logs of shit from her asshole. They fell down into the water below, leaving Mukuro to have a sudden taste in her mind as her face scrunched up. Normally she’d be disgusted but in her current toilet form, it had affected her mindset and made it not taste too bad. Her mind told her to take it all in as she was just a toilet, but the girl wanted it to all be over already. It lasted quite some time though as Komaru pumped a day’s worth of shit into her friend. It got so filled she had to flush right away when she was done. Komaru pressed on the flush lever and let her mess get pulled away down below the city. The lever was Mukuro’s nose, leaving the girl to feel a slight pinch for a moment before the gross contents left her mouth and left her at least feeling a tiny bit better it was gone. It went down Mukuro’s anus piping, leaving the girl to feel like she was shitting out something herself, though in reverse. Just as she was about to stand, Komaru felt the need to go pee hit her, so she decided to relieve that urge too. A long stream of piss streamed out into the toilet and messed with Mukuro’s mind. It was acidic and warm, the taste being gross, yet Mukuro’s messed up mind wanted it to fill her. After a minute of pissing, Komaru cleaned herself up and flushed once more. Komaru put the lid of the toilet down and looked at Mukuro, struggling to make eye contact with her as she felt a bit guilty from it all. The soldier just awkwardly blushed as she felt her lid pressed back down and she saw her friend’s face.

“Alrighty, I think I’m all saved before the fight… Let’s get you restored Mukuro!... Huh?”

“(W-What? What’s wrong?)”

“Well… I guess since you were so close to the building, it made you a part of the structure… So until I can disconnect you…y-you’re stuck like this…”

“(W-WHAT?! You’re joking!”)

“N-No… I don’t have any tools on me so… I’ll have to get a tool of some kind to help unscrew you… But the boss is right here…  We really don’t have time to mess around so… I guess I’ll have to go fight it myself and come save you later… I really wish you could come but we have no time… H-Hopefully you don’t mind Mukuro…”

“(Guah. Well nothing we can do. Just come back before it gets too late… and don’t leave me here! Last thing I need is to live life as a toilet.)”

“Alright! I’ll be back as soon as I can! And hey, keep watch for me, ok? Never know when you might see a hostage or an enemy coming to get me!”

With that, Komaru was off to the final boss as Mukuro was forced to sit around, now stuck as a toilet for the time being. She should be able to get back to normal soon, though being stuck in this weird state for a foreseeable amount of time was less than exciting for her. All she could do was sit there, an immovable object now with her mind slightly altered. She knew Komaru wanted her to keep an eye out for any extra hostages, but she partly didn’t want anyone to find her. The last thing she wanted was for one of them to rush into the bathroom and start using Mukuro before she could speak up. Or even any of the other adults for that matter if they needed to go while rallying against the Monokumas… At the very least, she should be back to normal within a few hours. Of course, even at the end of their quest, after all, they were going against the final boss sure, they still had plenty of a mess to clean up here and there. Mukuro was pretty sure she was going to have to transform plenty more to help Komaru get through all the various remaining Monokumas and other obstacles in their way. At the very least, she was happy to help assist the girl through it all. Once all of the hostages were eventually safe, they’d be able to leave the city and Mukuro would be able to spend some time relaxing with Makoto. For now, all she could do was sit and wait, praying she didn’t get used in her current state anymore…
