Chapter Text
Mukuro had it rough. A tough childhood. A complicated realtionship with her sister. A path that was filled with blood.
She didn't complain about that stuff. It was her life. And as difficult as her sister could be, she loved her. Deeply. Maybe more than she should.
So it felt worse that she had such a minor complaint. such a petty issue plaguing her, but...
She really wished she didn't have such a big, fat ass.
It was stupid. She shouldn't worry about such things. How many lives had she taken? How difficult was her sister's life with her obvious extreme mental illness? Junko and her had to do a lot of terrible things to get by...
But it still bugged her. Her big ass drew a lot of attention. It was sometimes difficult to find clothes that fit, especially since the rest of her frame was fairly athletic. Sometimes she'd knock things over or bump into stuff with her ass, which was just embarrassing. It even made stealth missions a bit more complicated sometimes.
It made it worse that Junko knew too. Knew how much it bothered her.
"Heya fat ass." Junko said, slapping said rump as she slid into her room. Junko was already dressed in her Hope's Peak uniform, which was honestly surprising. Usually, she didn't give a shit about dress codes. She looked damn good in it, though.
Mukuro blushed. Her ass even jiggled a bit, which didn't help her sense of intense embarrassment.
"Junko..." Mukuro said.
"Aw, come on, Mukoro-Chan. Don't be a fucking buzzkill. You've got a real badonkadonk girl. You should flaunt it. " Junko said, she lay across her bed.
"No, thank you." Mukuro said, blushing.
"Really? Not even for me?" Junko said, fluttering her eyelashes.
Mukuro felt a shiver of arousal. Fuck, she was down bad for her. Her own sister. It made her sick, but at the same time...the fact that it was forbidden only made it feel better. hotter.
Junko would get a kick out of it. With her whole despair fetish shit. It made Mukuro relate to it. Just a little bit.
They were both fucked up. That fact made Mukuro a bit warm.
Mukuro didn't respond with anything more than a scoff. She finished getting dressed I. her Hope's Peak uniform. The skirt clung to her rear end more than she would have liked, enough as it was. The outfits Junko kept trying to shove her in (and unfortunately sometimes succeeded) were even worse.
"Aw, you are no fun." Junko said, bouncing off of Mukuros bed.
"Your ass still looks mega cute in that though." Junko said slyly and slapped Mukuro's ass again. It jiggled,d and Mukoro sighed.
"I wish I had an ass that nice." Junko said.
"Please, you are the ultimate fashionista. Your ass is-" Mukuro said, her dumb mouth moving before she'd thought things through.
This is why Mukuro preferred to stay silent.
"My ass is?" Junko said with a Cheshire cat grin.
"I mean...it's model perfect, honestly. Way better shaped and the perfect size. not too big or small." Mukuro said, her gaze on the floor. If she didn't answer, Junko could extract even more damaging information from her silence.
Junko was scary.
"Aw, you are soooo cute when you are lezzing out!" Junko said and gave Mukuro a tight hug. Mukuro felt her arousal increase as Junko's arms wrapped around her and she pushed her considerable bust against Mukuro's more modest breasts.
"I-I'm not l-lezzing out. It's just the truth." Mukuro said. Her attraction towards Junko aside, those were her real feelings. Mukuro did envy Junko's backside.
"Yeah, sure. I know my ass is quite nice. Despair-inducingly nice. But sometimes...I'd kill for a derriere like yours." Junko said her hands snaking down to Mukuro's bottom and giving it a firm squeeze. Mukuro let a gasp.
Junko gave Mukuro a last kiss on the cheek and went skipping away. As she did so Junko's skirt kept flying up, giving Mukuro peaks of Junko's panty-clad rear.
Mukuro really did have it rough. Still, it wasn't all bad. She at least had a nice view.

Mukuro needed to take her mind off of weird things.
Like how nice her sister's ass looked in her skirt.
Or how her cleavage was mouth-watering.
She needed to think of normal things.
Like that cute boy in her class. Makoto Naegi.
He was sweet and kind. and way smarter than you'd expect from such a seemingly normie kinda guy.
Plus, he had a really cute butt. They were in the gym, and he was wearing shorts that really accentuated that feature.
"Hey yo perv." A familiar voice said as she slid close to her.
Junko Enoshima. Her despair-inducing, severely mentally ill sister.
"J-Junko-?"
"He does have a really cute tush, doesn't he?" She said, grinning uncanily broadly.
"Jun-Junko..."
"It's a shame he has a small dick." Junko said.
"What? That's awful to say, and how would you even.." Mukuro was blushing heavily.
"Small dick beta energy. Besides, take a look at the front of his shorts. Those things show everything." Junko said.
"-You are so gross." Mukuro said, looking away and blushing. Junko was the only one who could get under her skin like this.
"Oh come on. You were fantasizing about that Naegi Cock before I said a word." Junko said.
"No, I was not!" Mukuro said. But as per usual, Junko could see right through her.
"Oh come on. I always know when you have a crush. sometimes before you do!" She said her words sounded sweet, but they were poison.
"That's not true."
"Really? You didn't like that model I posed with? Or your blonde squadmate? Please. I know it all sis." She said, grinning her shark-like grin.
"It's a shame though." She said, putting her soft hand on Mukuro's plump ass. She put her mouth against Mukuro's ear.
"Makoto's tiny ass dick could never handle a booty like yours." She said, and her hand gave her ass a squeeze. Mukuro whimpered half in pleasure and half in shame.
"You two. Get your asss in gear!" The PE teacher called. Junko gave Mukuro a hard smack on her ass, and Mukuro again let out a little gasp as her booty jiggled in response. Then Junko ran off, and once again Mukuro caught just a glimpse of her panties.
She was such a tease. Mukuro wanted to corner her, kiss those perfect lips of hers, grab those big beautiful tits, and-
Mukuro shook her head and started to run.
The showers were the hardest part. Mukuro had to act composed around a bunch of naked women. Mukuro was bi but she far preferred the fairer sex. and the hopes peak girls were particularly fair.
The first thing she saw was Asahina take off her bra, exposing those big, bouncing boobs of hers, and Mukuro had to fight the urge to stare and drool.
Mukuro was just glad that Junko had to shower alone due to her inability to...control her desires in the shower. That made her feel bad. Junko couldn't control her mental issues, but in this one way at least, it helped Mukuro curb her lust for her sister.
Still she had to prevent herself from gawking at Kirigiri's well-shaped bare ass. So how much did it help?
Mukuro stripped down and got in the shower with the rest of the girls. As per usual, she was terrified that the other girls would sense she was aroused by them. So she stared straight ahead at the shower wall.
"Woah." Mukuro heard a voice near her say, and she knew it didn't bode well.
"Did anyone notice what a big booty Mukuro has? Like girl, you've got it going on! " Hina said.
"Wow, Hina, you are correct. She does have a splendid backside." Sakura said. Mukuro felt herself go stiff. She was the only person that could conceivably physically threaten Mukuro. If she wanted to take her ass for a ride, she might be able to.
Fuck that shouldn't make her so wet.
"That is unexpected. I knew she was packing something down there but it's more impressive naked by far." Celestia said.
"It was obvious. She was trying to conceal it, but I could tell." Kyoko said.
"That really is impressive, Kirigiri-Chan. Is that because you are a detective or...are you a psychic too." Sayaka asked.
This was all way too much attention for Mukuro. She felt an intense desire to flee.
Kyoko gave her a look.
"Girls, we should probably stop. Mukuro looks a bit...overwhelmed." Kyoko said
Hina looked confused.
"Why? it's just girls being girls!" Hina said.
"Yes...but she's the ultimate soldier. I don't think she's used to this much...attention from other girls." Kyoko said.
"N-no you are right. I was the only girl most places I served." Mukuro said.
"Oh...Poor thing. I couldn't imagine being around only guys!" Hina said. For some reason, Sakura blushed at this.
"O-of c-c-course sh-she wouldn't." Toko muttered.
"It's ok. You'll get used to it." Sayaka said.
Somehow, Mukuro highly doubted it. A bunch of attractive girls all naked around her? How the hell was she supposed to get used to that?! All these boobs and butts and curvy hips and long legs and vaginas and she just didn't know where to look! She knew she wanted to look everywhere...
"By the way, where is Junko? Why doesn't she ever shower with us?" Hina asked.
Kyoko scoffed, as if it was obvious.
"If us girls get a bit handsy in the showers...well, with her it would be on a whole different level." Kyoko said. Hina looked at her with a bit of surprise and...interest.
"Is that true, Mukuro?" Hina asked.
"...Yeah. I mean, is it that surprising? She's er...grabbed your er...chest before already..."
"Huh. That's true." Hina said.
Mukuro at last got through the shower and got dressed. She had barely gotten out of the girls' locker room, and suddenly Makoto was pushed in front of her.
"Ma-Makoto?" Mukuro stuttered.
"Go on, Shorty! Ask her!" Junko said.
Makoto was blushing heavily.
"I um...well, it's not anything too er serious. I just wanted to know if you'd like to hang out sometime." Makoto said. Now Mukuro felt a blush coming on.
"Um...sure. That sounds...nice." Mukuro said. The fuck. she was a soldier. This shouldn't be so hard.
"So uh...maybe Friday? After school?" Makoto said.
"Sure. sounds...good." Mukuro said.
Makoto nodded, said goodbye, and sheepishly walked away. Junko gave her a wide grin.
"See! I knew that boy couldn't resist your big fat ass!"
Mukuro didn't think that was true. But if it was...maybe having a big ass wasn't so bad?
Probably not. Makoto was probably just being nice.
And oddly, Junko was too.
