Chapter Text
Miu helped Kirumi clean up the plethora of minuscule shards scattered throughout the dining room. However, it was made much more difficult due to her incredibly sore behind. Miu sniffed a little as the aftermath of her crying tantrum earlier waned off. Her mind was running on autopilot, brainlessly following Kirumi and cleaning up her mess.
When the girls were finished, both returned to their respective bedrooms as if nothing happened. Miu’s energy was completely drained from the night, and dove into her bed without changing clothes. She wanted to work more on some inventions tonight, but she did not have the energy for it at all. Instead, she lay on her back, staring at the ceiling, trying to try and comprehend what had happened to her in the previous hours. So many drastic, unexpected changes happened so fast.
As Miu lay contemplating the previous night, she only got more and more angry. What gave Kirumi the right to treat her like that? Humiliate her in front of her fellow peers, who most likely will tell everyone else?
Miu laughed. Kirumi thought her disciplinary methods would help Miu learn how to behave? That she’d now be more well-behaved and docile? Fuck that noise! Miu’s laughter increased in volume, thinking of how Kirumi’s stunt had the opposite effect on her. All she wanted to do now was rebel against Kirumi even more than she did before! She’d be a total bitch to everyone, and wanted to see how far she could push Kirumi. Miu fell asleep happy and in anticipation of her new plan for tomorrow.
It’s a perfect plan. Flawless. Nothing could possibly go wrong.
—————————
Miu woke up and stretched, her ass still sore. But she didn’t care. She was going to show Kirumi how much she didn’t care, how much she wasn’t going to listen to her. She sauntered out of her bedroom and strutted around the dormitory hall. Kaede and Tenko glued their eyes onto Miu, who flashed them a devilish smirk. The pair of girls had to choke on their laughter to stop Miu from hearing it.
Miu walks out of the dorms and around the school with no destination in mind, just waiting until she comes across Kirumi. She paces around the school like a shark, unable to stop, and must stay in motion until her prey is acquired. In a random hallway she has no care for, Kirumi calls out Miu’s name, to which the strawberry blonde inventor immediately whips her head around to catch the tall maid.
Miu stalks her way over.
“How did you sleep last night, my dear?” Kirumi questioned, not even a change in her tone as if to imply a rowdy occurrence last night.
A smirk slowly creeped its way across Miu’s face, which then split itself into a toothy grin. “Like a fuckin’ baby.”
Kirumi’s pleasant face quickly morphed into one of disapproval. She raised her eyebrows, before lowering them again into a serious expression.
“Language please, sweetheart.” Kirumi muttered.
“Fuck you, bitch!” Miu yelled. “You think you’re gonna turn me into some good, obedient little girl with just a few slaps on the ass? Ha ha! It’s gonna take more than that to make me behave how you want, you pretentious cunt!” Miu laughed uproariously.
Kirumi sighed, then developed a more serious tone. Whatever she had to do to show Miu she wasn’t messing around. “I don’t like your behavior, young lady. I suggest you better drop it right now. This better be some kind of joke.”
Miu backed away a little bit, only beginning to get intimidated. “Yeah?! Well, the fuck you gonna do about it, huh? You’re not my fucking babysitter, bitch!” Miu spat.
Kirumi had enough. Clearly Miu was testing her. The maid gripped the inventor’s collar and pulled her closer.
“No, but if I remember correctly from last night, I’m your…’mommy’...”
Miu’s face flushed red. “Y-yeah..? Well, that’s just ‘cuz Kaede was watching…! And...I w-wanted to make her jealous…!” Miu stuttered, clearly desperate to string together a convincing lie.
“Mmm hmm…” Kirumi groaned, not believing Miu for a second. “Well, I did assume your behavior had changed, and you were such a good girl last night, I thought I’d treat you this morning. I was going to ask if you wanted to come to the dining hall with me this morning and we could make a special breakfast together, but you clearly don’t deserve it.”
Miu’s cocky face had dropped...maybe in some sort of attempt to make Kirumi empathize. But, inside her genius brain, Miu was elated at the opportunity to wreck more havoc for Kirumi on purpose. She tried her best to act as pathetic as possible and beg for Kirumi’s forgiveness.
“N-no..! Kirumi…! I didn’t mean it….I’m sorry! You’re right, I was just trying to play a joke on you….haha! I’m...fine, mom...I mean, Kirumi. That sounds really fun...could we get breakfast together? I’m sorry for being a brat…to you this morning. I promise I’ll be good! I’ll behave…! I just...I just like teasing you is all!”
This seemed good enough for Kirumi, who could see right through Miu’s painfully obvious fib. She cracked a pleased smile. “That’s wonderful, Miu. Why don’t you follow me down to the kitchen and you can see what you would like to make, hmm? Does that sound good?”
Miu nodded rapidly. “Let’s fuckin’ go…!”
Kirumi glared at her again.
Miu giggled. “Heh heh, sorry.”
When the pair arrived in the kitchen, Miu searched around the kitchen. “I dunno how to make anything...so you’re gonna have to tell me what there is to eat in here.”
“That’s quite, alright my dear.” Kirumi said. She made her way over to Miu, and subtly slid behind her. Her arms gently wrapped around Miu’s waist, giving little kisses on the inventor’s neck. Miu whimpered at the contact, and was desperate for Kirumi to touch her more.
“Mommy’s right here, just for you…” Kirumi moaned breathily in Miu’s ear.
Miu trembled, but was still hoping to put up more of a fight with Kirumi. “Y-yeah…? You want me so fuckin’ bad? And what’s with the ‘mommy’ shit? Cut it out!” At the deliverance of the last sentence, Miu sent a hard kick behind her, trying to get Kirumi off in any way she could. The big heeled boots of the invention drove right into Kirumi’s leg, pushing her away as she grunted in pain. She had expected Miu to act up, but not in this way. Now she was mad, and she was letting Miu know it.
Kirumi stood up straight and grabbed the inventor by her collar yet again. “I really thought you changed, Miu.” She spat. “Turns out, you're just as much of a little brat as you were before. You’re going to learn how to behave, missy. Whether you like it or not…!”
“Fuckin’ make me…” Miu growled. She picked up her foot and kicked Kirumi in the shins yet again. While the blow hurt, Kirumi stood as strong as she could, and tried to look unfazed in front of Miu.
“Do that one more time, and you’ll regret it, young lady…”
Kirumi could easily predict what was going to happen next. When she saw Miu bring up her foot, Kirumi hurled the inventor from her grip on the collar. Kirumi spun around with Miu, and shoved her against a counter. When she let go of the inventor, she stumbled into the counter and swung her arms on the countertop to prevent her from falling over. In this process, she knocked over a large vase of flour that was sitting at the counter’s edge. The heavy clay container fell to the ground with a loud thud, shattering. Fine white powder flaked across the kitchen floor like snow.
Kirumi placed her hands on her hips and looked at the fallen inventor below her. “Tsk tsk tsk…” she tutted. “Looks like you’ve made a mess. Well, what are you wanting for, missy? Clean it up.”
Miu jumped up from her fallen position on the floor and snapped at Kirumi. “The fuck you mean, clean it up?! You made me spill it! And besides, you’re a fucking maid? Isn’t that you’re fucking job?! The fuck! Don’t…!”
“Is that any way to speak to me, young lady?” Kirumi gnarled through gritted teeth. “I am appalled at how much of a misbehaving, spoiled brat you’ve become. I’ll give you one more chance, or else you’re going to regret it. Clean up that mess. Now.”
Miu let out a cocky guffaw, right before getting her mouth lubricated and spitting on Kirumi’s face. The maid’s expression remained stonelike, unchanging. Then, the final blow was given. One final kick in Kirumi’s shins. The maid bent over a little bit as she winced at the pain, but that was quickly dissolved once the rage filled her.
“Fine…” Kirumi growled. “Have it your way, slut.”
That last word scared Miu. The last time she heard Kirumi use language like that was, well...last chapter, and she remembered what had happened there. Miu suddenly realized she may have gone too far, but didn’t have time to think as Kirumi grabbed her wrist and dragged her out of the kitchen.
“No...no…! NO..!!!! Stop...Kirumi…! I didn’t mean it..! I’m sorry for being a bad girl.. .you know I want to behave…! Stop it Kirumi…! Stop...STOP!!!”
Miu’s fighting was pointless. The maid was going to continue to drag her, and showed no signs of weakness or any chance of loosening her grip. In desperation, Miu sank to the floor and tried to weigh Kirumi down, but the maid was more determined than ever to show the naughty little bitch how to have a little respect. Miu kicked and screamed as she was dragged down the school’s corridors; her wails echoing through the school walls. Some students poked their heads around to see what all the commotion was, and no one was really surprised. Kokichi, Kaede, and Tenko, of course, all had to laugh when they saw the whole ordeal. But their laughter fell on Miu’s deaf ears. Her eyes were so full of desperate tears that she could barely comprehend faces, or where she even was in the school. Her screams and cries of desperation and fear, begging Kirumi to let her go, are all that clouded her mind.
After what seemed like an eternity to both the girls involved in the ordeal, they had arrived back in the dormitories, specifically Kirumi’s room. She unlocked her door, threw Miu inside, then stormed in after her, slamming the door shut.
“My, that was quite the tantrum you threw back there, missy. Someone’s extra cranky today. Maybe you’re hungry…”
“FUCK….you…!!” Miu screamed in gaps since she was so out of breath.
Kirumi grabbed Miu’s shoulders, and guided the helpless inventor to the bed. She tossed Miu down, then climbed over her on the bed to straddle her legs around Miu’s hips. She bent down, arms planting on either side of Miu’s head.
“After that little stunt you pulled today, my my. We have a lot of work to do. I told you. You were going to regret it.”
—————
Kirumi dismounted Miu flat on her back, and flipped her over so her ass was exposed in the air again. She raised Miu’s skirt and gave another one, two, three swift smacks on Miu’s already desperately sore bum.
“Kirumi...stop it…! Ow…! It hurts…! Ow!!”
Four. Five.
“What did you say, dear? I’m afraid I don’t understand.” She said, clearly joking.
Six. Seven.
“M-m-mommy! Stop it, mommy! It hurts…! I don’t want anymore mommy..!”
“Well, then you shouldn’t have acted up.”
Miu kicked furiously as she screamed.
Eight. Nine.
“You’d better behave or else I’m adding more.”
“No, no, no! Mommy...please! I’m sorry…! Please stop, mommy! I’ll be a good girl…!”
Ten.
“Are you actually sorry? Or are you just saying that so I’ll stop?”
Miu hesitated and wailed. “I...I don’t...I’m actually sorry, mommy! No more!”
Kirumi stopped, hitching her hands under Miu’s armpits to position her up in a sitting position. Miu was limp like a ragdoll, small tears streaking down her face.
“I guess I have to be a little nice to you. Besides, your punishment is only getting started.”
“P-punishment..? What are you going to do to me?” Miu whined.
“Teach you how to grow into a proper young lady. Bad girls like you require special training. You should be thanking me for putting in all this work to make you a better person.”
All Miu could do was whimper as Kirumi commanded her to “Stay here. Stay still.” She sat on the bed, frozen in place, chest heaving.
Kirumi opened a drawer in her bureau. She pulled out a plain cardboard box. In order to torture Miu as much as possible, she opened the box as slowly as possible. A bit of soft padding gently caressed the large...toy...inside of the box. The padding rustled as Kirumi lifted the big implement out of the box, and Miu’s mouth gaped open. An 8 inch long black silicone dildo attached to a symphony of fabric straps rattled. Miu’s breath sharpened as she sat dutifully on the bed waiting for whatever Kirumi had in store for her. Kirumi sauntered over to her subject on the bed and smirked as she suggestively stroked the shaft.
“Mommy….w-what...what are you going to do...with that..? I-it looks too big…!” Miu stammered as she slid up the back of the bed, like she was trying to somehow escape Kirumi.
“Why are you suddenly so scared, my darling? You seemed very, very confident in yourself not a few hours ago. I suppose you’re nothing but a fragile little girl who breaks once she’s put back in her place. I just need to make sure you stay in that place.”
Miu cried harder, her breath exiting sharply and quickly throughout her teeth. “Mommy...plea-ea-eas!” She yelled. “I don’t want it! I promise I’ll be good from now on! Please stop…!” Miu screamed as she tried to scramble off of the bed. Miu had to grab her and hold her still. “If you don’t start listening to me this second, young lady…” she snapped through Miu’s thrashing.
After a short while, Miu got tired from throwing a tantrum and all that yelling. She flopped limply in Kirumi’s arms and panted.
Kirumi just knelt on the bed and waited patiently for Miu to calm down.
“Are you done yet?” She whispered.
Miu gave a tiny nod. “I’m sorry, mommy…”
Kirumi smiled at Miu’s realization she wasn’t going to get her way. “Good girl.” She said, petting Miu’s hair gently.
“Now, I want you to undress yourself for mommy. Right here on the bed. I hope you don’t need my help. You’re a big girl, and should be able to do it yourself.
“Mmhmm…” Miu whined. She slid her pink top over her head and threw it off to the side, then slid her skirt down down her legs, off of her feet. She was kneeling on the bed in front of Kirumi in her underwear. Before she could do more, Kirumi stopped her.
“Now, undress me.”
Miu nodded. She crawled over to the maid, trying to figure out how to take off her complicated, ornate outfit. She fingered with tied strings, buttons, and claps before she slid off the maid’s black top, white undershirt and big skirt. Kirumi remained in her underwear as she commanded Miu to take off the rest of her own clothes.
Miu unclipped her bra, threw it off the bed, and slid her panties in the same direction as her skirt. Kirumi chuckled, looking satisfied as the blonde’s figure.
“Okay, baby girl. You seem ready now.”
Kirumi stood up off the bed to put the strap on. It stood erect in front of her waist as Miu gulped.
“Get over here, you slut. Make yourself useful for once and get this cock all lubed up before it gets rammed inside you.”
Miu slowly crawled on hands and knees across the large bed to meet the corner at which Kirumi was standing. Kirumi steadied the shaft in her hands as Miu moved her face closer to the tip. She wrapped her lips around the end, which Kirumi took as a sign to start bucking her hips. She grabbed a mass of Miu’s hair to hold her in place while she humped at Miu and pulled her head closer to her waist. The sound of light gagging was heard from in between Kirumi’s legs. Miu tried to allow as much spit on the strap as possible, and it didn’t even matter to her at this point if she could breathe.
All she needed to do was make Kirumi happy.
Kirumi moaned as her “cock” went in and out of Miu’s throat. Of course she couldn’t actually feel anything, but she let out low, seductive groans to see how much of a whining, desperate horny mess she could make Miu before she fucked the brat right out of her.
After the maid was satisfied, she pulled Miu’s head away from the shaft. A trail of drool followed Miu’s mouth, and her eyes were red, puffy, and pooled with tears.
“Are you ready for more, my dear?” Kirumi said in a sultry voice as she gently pushed Miu down on her back onto the bed.
“N-no...I...I can’t….I can’t take anymore, mommy…”
Kirumi tutted. “My, I’m sure you can! Look at you, you’re practically drowning…” She emphasized that last word as she aggressively slid a gloved finger up the length of Miu’s entrance. Miu squirmed under her touch and whined.
“Mommy...please….”
“Please what, dear? Use your words for mommy.”
Miu wailed.
“The longer you keep stalling, the longer your punishment is going to be, dear. I suggest you tell me now.”
“I...want...I want you so bad….”
Kirumi smiled. She had finally broken her.
“Perfect, That’s just what I want to hear.” She climbed onto the bed with Miu and knelt by her side. She instructed Miu to get in a doggy-style position on her hands and knees. It took her some time...her muscles were weak and she had been in heat this entire time, so it was very difficult for her to breathe.
Once she was positioned across the bed like Kirumi had told her to, Kirumi moved to Miu’s rear end that stood up in the air. She gave it one last big spank, a noise that echoed throughout the bedroom.
“Are you ready, my dear?” Kirumi said in a comforting voice as she gently rubbed up and down Miu’s back.
Miu let out a feral growl before uttering out, “Please, mommy….fuck me up…”
“As you wish, my dear.”
Kirumi teased Miu for a few seconds, but then slowly slid the tip of the strap-on into Miu’s glistening folds. Miu let out a high-pitched whine that dropped down in pitch the further Kirumi went in. Miu’s walls tightened around the shaft of the cock and they left it soaked. Once she was a good few inches into Miu, the maid began thrusting it at a tortuously slow speed inside the inventor. Miu gasped and whined with every thrust.
“Harder, mommy...harder..” she mewled pathetically.
Kirumi cocked an eyebrow. “Really? This is meant to be punishment, and you’re telling me you enjoy this?! Figures...worthless little sluts like you are desperate for any attention they can get.”
She sped up.
“M-m-mommy…! I...ugh! Ahhhhhh!!” Kirumi gave a light spank.
“You’re so fucking pathetic that you need to bred by me to behave like a good girl?”
“F-fuck…! Mommy…! I’m…..ugh..!! AHhhhhhHHHHH!”
“Watch your mouth, young lady.”
“I want...mommy..! I need…! I need you, mommy! I need you, mommy!”
“I know, sweetheart, I know. You only acted like a naughty girl before because you’ve never had a proper mommy to take care of you. That’s why...I’m here…”
Kirumi humped wildly, hitting Miu from behind. Six inches of the strap-on dove in and out of Miu, the pain and pleasure making her grip at the sheets.
“You want it? You really want more? How bad do you want it?”
“S-so bad, mommy! I need it...so bad! I’ll be a good girl…! I’ll never misbehave for you ever again!!”
“There we go. That’s it.” Kirumi said quietly. She gripped Miu’s shoulders to pull her in closer, and Kirumi bowed her head down to Miu’s ears.
“Beg for mommy to fucking break you.”
And she did.
“M-m-mommy..! I need you and your cock so bad..! I...please…! More, mommy! More…! I’ll take it…! I can…!” Miu cut herself off due to breathy sobbing.
“What’s wrong, my dear? You’re going to cry? You’re supposed to be a big, big girl right? Big girls don’t cry, Miu!”
‘AHHHHHHHHhhh!!!” Miu let out a deafening scream, head bowing down and fingers practically ripping the sheets.
“Imma...Imma...I’m a big girl, mommy…! I’ll...I can take it, mommy! Give it to me, mommy…! I’ll be a big girl..! Imma big girl!”
“Well, you certainly are not acting like one! I’ll make sure you act like a big girl after I’m done with you.”
Kirumi was bent over Miu’s body, their thighs clapping against each other. Kirumi’s bangs that swept over her forehead were drooped down and bristled on Miu’s back. Kirumi was exerting a lot of effort as well, her beads of sweat dripping onto Miu’s sensitive skin.
Violent thrusting, panting, screams, and swear words filled the room for minutes on end. All track of time was lost for both the girls, but Miu especially felt like she was floating in space. She couldn’t feel anything other than raw lust and desire for Kirumi, and could only hear her own breathing and yelling.
“M-mommy..! Mommy…! I’m so close…! I’m almost...let me finish...mommy!”
“That’s it, baby girl. There we go. Cum for mommy...let it all out and cum for mommy.”
As Miu got closer and closer to climax, Kirumi stroked Miu’s back and shushed her.
“Shhhhh, shhhhh, shhhhh. It’s okay, mommy’s right here, sweetheart. Relax for mommy. Shhhh shhhh, you’re doing so good, my dear. Just let it all out.”
She continued to pet Miu’s back as Miu screamed, her voice getting more and more breathy.
Until it stopped.
Until her mouth gaped open into a silent scream. Every muscle in her body relaxed and went limp in front of Kirumi. The maid dramatically slowed her thrusting down, letting Miu crash down after the wave of her orgasm.
After a few minutes and both girls were able to catch their breath, Miu laid on her stomach on Miu’s bed.
Kirumi stood up off the bed to put her own clothes back on. She wiped sweat off of her face, and tossed Miu’s own clothes back onto the bed.
“You can relax until you’re good and ready.vGet dressed whenever you feel like it. I must head out now. Thank you for your lovely behavior. I hope it lasts.”
“Thank you, mommy….Wh-where are you going..? I want you…”
Kirumi smiled as she walked out the door. “I have to make tonight’s dinner.”
