Submission Quirk – Mummy!Domme!Reader x Little!Boy!Dabi

**This oneshot caters to MD/lb (Mummy Dom/Little Boy) role play kink as well as ageplay kink.

Sexual ageplay refers to ADULTS engaging in sexual activity where one or more adults are role-playing an age that is not concurrent with their actual biological age. Some people age play as older, and some age play as younger.

Ageplay should only ever be practiced between ADULTS of sound mind, where mutual consent is the centerpiece of the roleplay.

Ageplay should NEVER be engaged in between Minors OR between a minor and an adult. 

Ageplay is NOT pedophilia because there are no children involved. Ageplay is performed between adults ONLY who are role playing a behaviour typically associated with a certain age group.

In this oneshot, Dabi is displaying behavior associated with a younger age but his actual age is 24 and the reader will be noted as the same age (24) (for clarification purposes).

…………………………………………

“Dabi~,” you sung out when you heard the front door open then close, heralding the arrival of your boyfriend.

There was silence in reply to your call, so you jumped off the bed and skipped out and down the hallway to go and see where he was.

Usually Dabi would reply your call but today something was different.

He wasn’t even at the door when you got there.

“Dabi?” you called again, turning and walking into the lounge roomful see if that’s where he had gone.

As you stepped into the room you saw him. Dabi, was curled up on the lounge, hugging a pillow to his tummy and you looked at him in surprise.

“Hey? You ok?” you asked as you approached him.

His half lidded, turquoise eyes found yours and he just looked at you before grunting and looking away.

“This isn’t like you?” you said, crouching down beside him, “what happened? You were supposed to take on some people today…”

“Mm,” he grunted, scrunching himself smaller.

“We need to get you to the doctor,” you said worriedly, “something has happened to you.”

You took his hand and dragged him to his feet then put your shoes on and dragged him out the door with you.

10 minutes later you were at the quirk doctors office. Now, because you and Dabi were part of the villain underworld, you had your own doctor who was, well, not as straight laced as his hero counterparts were but would help any villain out who was in need of medical attention.

“Hi,” you greeted the receptionist at the building, “we need to see the doctor… something is wrong with my boyfriend.”

You looked back at him and noted that he had his free hand shoved into his pocket and was digging his toe into the floor as he sheepishly looked around.

“I see,” the receptionist said, “take a seat and the doctor will be with you shortly.

You nodded and squeezed Dabi’s hand then walked him over to a chair in the waiting room and sat down.

“What’s wrong with me… mummy?” he asked in a soft voice.

You nearly keeled off your chair.

“Mummy?!” you whispered harshly with surprise, “did you just call me, mummy?!”

He looked away, almost embarrassed by what he had just said and you stared at his side profile for the longest time, trying to figure out what on earth was going on.

This wasn’t Dabi. The Dabi you knew was in charge, dominant, always on his game, and loved for you to call him daddy or master… so what had happened? Why the sudden change??”

“Y/N and Dabi?” the doctor called as he walked out of the office.

You got up and pulled Dabi up too, then followed the doctor into his office.

………………………………..

“A submission quirk?!” you said with surprise when the doctor gave you the verdict, 20 minutes later, “what does that mean exactly?!”

“It means that he is now in a submissive state.” The doctor set his instruments down and looked at you.

“Umm… ok? So why is he acting… Umm…”

“Childish?” the doctor offered.

“Yeah… he called me ‘mummy’ in the waiting room?” you replied, still slightly stumped by this.

“This quirk has quite an interesting effect. You see, people all have a dominant side and a submissive side,” the doctor said, “your Dabi is most likely always in his dominant side…”

You nodded in agreement and let the man continue.

“… so this quirk has pulled his submissive side to the foreground instead. It’s switched his sides up. For someone who is always submissive, this quirk would flip them to their dominant side.”

“Ohhh,” you hummed, looking at Dabi, who looked away with an embarrassed look on his face. 

“This isn’t to say that this quirk has created an artificial submission. Dabi is in full control of himself- what he expresses to you under the influence of this quirk is his true desires as a submissive, so pay attention,” the doctor added.

“Ah… ok… umm… ok, but when will this quirk wear off?” you asked.

“That’s the other thing,” the doctor said, a little hesitantly due to a small amount of embarrassment, “this submission quirk is acting on his sexual desires… so it will only resolve once he has… released….”

“Released?—oh! Ok… I get it…” you said, scratching your cheek with embarrassment, “so let me get this straight… Dabi is acting out his inner fantasies as a submissive right now and all I have to do is get him to uh… yeah… and then he’ll be back to normal?” 

The doctor nodded. “There’s not really anything else I can say right now so I’ll let you go. But if it still persists after he has completed his release, then bring him back.”

“Ok,” you agreed, standing up and holding your hand out to Dabi, “let’s go, uh… my boy?”

Dabi’s eyes shot up and met yours, your words sparking something deep inside him and he took your hand and stood.

“Thanks Doc,” you mumbled to the doctor as you left with your very strange acting Dabi and headed back home.

………………………….

Once back inside, you led Dabi into the lounge room again and sat down on the lounge chair together, mentally trying to figure out how you would tackle this.

As you sat back, Dabi lay his head on your shoulder and placed his hand on your tummy, snuggling gently into you.

“This is really weird but I kinda like that he’s a bit clingy?” you thought as you paused before placing a hand on his head and ruffling his hair, “maybe I should ask him what he wants?” You turned your head a little and placed a delicate kiss to his forehead, “did you want something, little boy?” 

You felt his body react and he shifted his hand up your front, caressing under your breast.

“Uh!” You chided, “you need to ask before touching me.” You tapped his hand away and he withdrew it then tilted his head a little so that his mesmerizing turquoise eyes looked up into yours.

“I really want to touch your titties, mummy,” he said in a soft voice.

“What the ffffffuckk?!” your brain screamed, this was the exact opposite of what you were used to.

“Oh do you, little boy?” you hummed, finding that inner domme and pulling her forward, “well you need to do some things for me first.”

“What things?” he asked innocently, sitting up a little and twisting his finger into your shirt.

“Well? What would you like to do?” you asked, giving him the option to say what he wanted to do.

“Can I….” His voice trailed off as he looked down at your pants then pointed between your legs then to his mouth.

“Use your words,” you encouraged, “tell mummy what you want.”

“I want to put my mouth on there,” he said softly and your pussy pulsated.

“Well, you can do that. Help me take my clothes off,” you said, tugging on the top of your pants.

At being given permission to do as he wanted, he quickly got off the lounge and tugged your pants and panties down and off.

Still acting a little coy, he gently pulled your legs apart and kissed you on the inner thigh. 

“Is this ok, mummy?” he asked, tilting his head cutely to the side and you quickly covered your mouth to hide the smile.

“He’s acting so cute. I can’t deal with this. I mean, it’s different but I don’t hate it?” 

“Mmhmm,” you hummed, “good boy.”

He hesitated kissing a little further up your leg and you clicked your fingers and pointed to your clit.

“Here, boy,” you directed, encouraging him to kiss over your little bud.

You sucked a quick breath in as he pressed his lips to your clit repeatedly, kissing it tenderly and letting his tongue poke out just a little to wet your pleasure centre.

“Mmmm, such a good boy, licking me the way I like,” you purred, stroking your fingertips through his hair as he made eye contact with you and sucked down.

“Even as a sub he still has a killer stare,” you thought, maintaining strong eye contact in return.

“Do you like this, mummy?” he asked hesitantly, pulling back from between your legs.

“You’re doing a fantastic job, little one. Now lick my pussy,” you commanded, waiting for him to follow orders- which he did, dropping head head lower and swirling his tongue between your folds.

You gripped your thighs and pulled them apart then rested your head back against the lounge chair and let him work.

“Can I play with your titties now, mummy?” you heard him ask and you nodded while still resting your head back.

“Come and suck on mummy’s nipples while you put your thick one inside her pussy,” you said in an authoritative voice, finally dropping your head back down to look at him. 

With an eager nod of his head, he stood up and dropped his pants, his very thick shaft poking out immediately, pre-cum dripping from his excitedly swollen red tip.

“Come and put it in mummy,” you said, pulling your shirt and bra up to expose your breasts to him.

He stepped forward and crouched then hung over you, pushing his cock inside your throbbing pussy as he hunched over and connected his mouth to your right nipple.

“Ohhh,” you whined when he sheathed himself inside of you and started to thrust wildly.

“Mmmm, mummy, you feel so good,” he groaned, his hips bucking against you wildly.

“Slow down, little boy, you’re gonna cum too quick,” you chided, “nice and slow for mummy, ok?”

“Ok,” he replied, his speech and tone of voice really settling into the role that he had fallen into.

You let his tongue roam your skin, flicking over your stiff buds as he pleased himself in your pussy and you just let him have free rein for the time being as you were enjoying what he was doing. 

“Mmm,” he hummed, his calls getting more and more urgent as he switched back and forth from your left breast to right breast, his hips bucking that little bit harder.

“Ok, little one, harder… come on,” you said, “fuck me.”

Dabi complied, picking up the pace and thrusting deeper into you while he moaned out.

“Faster, little one, fuck me harder,” you commanded.

A deep groan escaped Dabi’s throat and his eyes rolled in his head as he pulled back from your breasts.

“Cum in me. Fuck me up,” you snarled sexually, panting harshly as you body rapidly ascended to the point of climax.

Dabi’s hips were still thrusting wildly as you came, crying out as he moaned loudly in response.

Suddenly his thrusting faltered and his legs trembled, signaling his release and you immediately grabbed him in a hug and pulled him down so you could hold him as he came.

“Is he going to go back to normal now?” you thought, waiting to see what he would do.

He stayed still for the longest time, panting as he lay on top of you, waiting to catch his breath.

“You ok?” you hesitated to ask him, trying to get a look at his face.

He wouldn’t look at you, flat refusing to make eye contact and then once he had caught his breath he pulled out of you then tucked himself away and turned to head for the front door.

“Hey!” you called out, quickly getting up with no pants on as you chased him to the door.

You quickly got in front of him and blocked his way, putting your hands up against the walls either side of the door frame.

“Dabi,” you said seriously, “where are you going?”

“Move.” His deep voice said threateningly.

“Oop. He’s back.”

“No. Tell me what’s up,” you demanded.

“I said, get out of my way,” he growled, grabbing your chin and tilting your head up as his burning gaze finally met yours. 

“Fuck me dead, there’s that dominant side.”

“No. We need to talk… I … I liked that…” you admitted, “you don’t need to be embarrassed…”

Dabi averted his eyes and let you go, pushing his hands into his pockets again. 

“I knew what I was doing…” he mumbled.

“I know,” you said quickly, “and it’s fine. I’m into it. Did… you wanna maybe do that again some time?” you hesitated. 

“I… if you want to then…”

You grinned. “It’s ok. We can work out the finer details later.” You gently reached forwards and put your arms around his middle. “It was kinda nice to see you as a sub.”

“I’m a dom at heart though,” he replied sternly.

“Oh definitely. You’ll always be my daddy.”

“Good girl,” he replied, reaching one hand to your head and patting your hair.
