Author's Note: A lot of you voted for R18, but I've also heard the request from two of my The Unrivaled King's Throne subscribers to keep the plot moving.
Because of this, I'm doing a double release! I'll post one R18 chapter, followed by a plot-focused chapter to officially begin the Sports Festival arc.
Huge thanks to everyone for voting!
Momo arrived home completely exhausted. Her social battery was drained after hours of forced smiles, polite conversation, and repetitive questions from distant relatives she barely remembered. But her heart was still racing.
What possessed me to do that? she thought, climbing the grand staircase toward the second floor of the mansion. What kind of proper lady sends that type of photo to a boy?
But even as she criticized herself, she felt it. A small tingling sensation traveled from her lower abdomen to her backside, making her stumble slightly on the steps.
Oh, God, she thought, grabbing the handrail. Not that too.
"What did you think of the party, dear?" her mother asked.
"Tedious but productive," Momo replied automatically, her voice perfectly modulated despite the chaos in her mind. "Uncle's associate seems satisfied with his retirement package. I consider the evening to have gone smoothly."
"Wonderful. Get some rest, daughter. You look tired."
"Thank you, mother. Good night."
"Good night, honey."
Momo climbed the remaining stairs toward her room, her heels clicking against the marble with every step. When she finally reached her door, she slipped inside and closed it behind her.
The moment she was alone, she let out a shaky sigh.
Her room was exactly as she had left it that morning: perfectly organized, elegantly decorated, everything in its proper place. The large ornamental full length mirror stood in the corner, its antique frame catching the light from her bedside lamp.
Momo kicked off her heels, feeling immediate relief when her feet touched the soft carpet. She sat on the edge of her bed, still wearing the black dress, and stared at her reflection in the mirror.
What an embarrassing moment, she thought, covering her face with both hands. I sent Hayashi san a photo of my breasts. And I...
She couldn't even finish the thought.
But the tingling sensation had not gone away. If anything, it had worsened. She felt uncomfortably warm, her skin sensitive under the tight fabric of the dress. Her breathing was slightly elevated.
This is ridiculous, she told herself firmly. I am a proper young woman. I should change into my nightgown, complete my nightly skin care routine, and go to sleep like a responsible person.
But even as she thought this, her hand moved toward her chest, her fingers tracing the necklace that hung between her breasts. The same necklace from the photo.
She shifted on the bed, trying to find a comfortable position. The fabric of her underwear rubbed against her in a way that took her breath away.
I need to calm down, she decided firmly. This is the accumulated stress from the party. I need to relax before I do something truly stupid.
She opened the browser on her phone and typed: "How to relieve muscle tension after formal events." The results were predictable: stretching exercises, hot baths, nightly yoga.
Then she saw something different: "Percussion therapy with massagers for sports recovery."
She clicked, scrolling through articles about professional athletes and heroes using high intensity massage devices for muscle recovery. The images showed gun shaped massagers with interchangeable heads, vibrating at variable speeds.
Interesting, Momo thought, examining the technical specifications. High torque motor, multiple speed settings, medical grade silicone head...
Her analytical mind was already breaking down the design. Her Quirk could easily create this. She positioned herself in front of the mirror. Her right hand began to glow with the familiar light of her Creation.
From her skin emerged the device exactly as she had visualized it: a matte black ergonomic handle, a quiet but powerful motor, and a soft silicone spherical head of the perfect size.
Excellent, she thought, turning it over in her hands. The weight is perfect, the balance ideal.
She reached behind herself, pressing the massager against her upper back while still fully dressed. When she pressed the power button, the device hummed to life.
Bzzzzzz...
"Ahh..." she sighed immediately.
The vibration was perfect, working her tight muscles with precision. She moved it across her shoulder blades, finding knots of tension accumulated from maintaining perfect posture for hours.
This was a brilliant idea, she thought, closing her eyes. Much better than staying awake thinking about...
But then, as she held the vibrating massager in her hand, looking at it in the mirror, a completely different thought crossed her mind.
The spherical head. The constant and intense vibration. The size. The soft texture of the silicone.
No, she thought immediately, feeling her face catch fire. Absolutely not. I created this for legitimate muscle tension, not for...
She couldn't even complete the thought.
But the tingling between her legs turned into a demanding pulse, as if her body had already made the decision regardless of what her mind found acceptable. Momo bit her lip, looking at her reflection. Her cheeks were flushed a deep pink. Her breathing had noticeably quickened. Her eyes looked darker than usual, her pupils dilated.
I am a future professional hero, she told herself firmly. I have a reputation to uphold. I should not be thinking...
But her body did not agree. The heat between her legs had become impossible to ignore. She had been in this heightened state of arousal for hours, from the moment she had pressed "send" on that first provocative photo.
She walked toward her bedroom door with slightly unsteady legs. Her hands trembled as she reached for the latch and secured it.
This is a terrible idea, she thought. But she turned the lock anyway.
The sound of the mechanism clicking into place seemed to echo in the silent room. Momo turned, leaning against the door and letting out a shaky sigh. She sat on the edge of her bed, the massager still in her right hand.
The full length mirror reflected her image clearly: her flushed face, her black hair starting to escape her elegant hairstyle, and the black dress hugging every curve of her body.
What am I doing? she wondered, staring at herself.
But even as she thought this, her free hand moved toward the hem of her dress, slowly lifting it. Inch by inch, exposing first her pale thighs, then further up, until she could see her underwear.
French black lace panties. Elegant, sophisticated, completely inappropriate for what she was considering. And completely soaked.
Momo bit her lip harder, looking at herself in the mirror. Her legs opened slightly, just enough to see how the delicate lace clung to her skin, darkened by the moisture. Her hand trembled as she reached down, her fingers hooking into the edge of the lace and pulling it aside.
Oh, God, she thought, unable to look away from her own reflection.
Her pubic hair was carefully groomed into a neat little triangle. Beneath it, her folds were completely visible in the mirror. Pale pink. Swollen. Glistening. She was genuinely wet. A clear fluid was already dripping from her entrance, forming a small thread that ran down her inner thigh.
Natural vaginal lubrication in response to sexual arousal, her mind cataloged automatically, even as her face burned with shame.
With trembling hands, she lowered the massager. The spherical silicone head touched her outer folds. The moment she pressed the power button, the vibration made her jump.
"Ah!" she gasped, almost dropping the device from the surprise.
Too intense, she thought frantically. That is too much...
But curiosity overcame fear. She tried again, this time prepared for the sensation, pressing more gently.
"Mmmh..." a soft moan escaped her lips.
The vibration against her hypersensitive skin was overwhelming. She moved the massager slowly, exploring her body and finding spots that made her breath hitch; areas that made her legs tremble involuntarily.
This is... this is incredible, she thought, completely unable to stop herself now.
Her free hand moved between her legs, her fingers carefully parting her folds to give the massager better access. Her clitoris was already swollen, protruding slightly from her intimate area. When the vibration touched it directly, Momo's back arched violently.
"Ahhh! Oh... oh, damn..." she moaned, much louder than she had intended.
Bzzzzzz... bzzzzzz... bzzzzzz...
The constant vibration against her clitoris was devastating. She continued, lost in the sensation. The triangle of pubic hair became disheveled as her fingers worked, spreading her moisture and giving the massager unobstructed access to every inch of sensitive skin. The sounds she was making were completely obscene. Nothing like the controlled, modulated, and professional voice she used at U.A. These were raw, unfiltered moans.
I should be quiet, she thought distractedly. The walls are thick, but not soundproof...
But she couldn't stop. Her body had taken control, seeking the relief she had been denying herself all night. Her eyes caught her reflection in the full length mirror. The image hit her with force: Momo Yaoyorozu, a girl of noble etiquette, student and class 1-A vice representative, with her legs spread wide, her dress hiked up to her waist, pleasuring herself with a device she had created specifically for this forbidden purpose.
I am vulgar, she thought. I am behaving like a...
But even that thought only intensified her arousal. Without fully processing what she was doing, Momo adjusted the angle of her phone. She spread her folds with two fingers using her free hand, exposing the bright pink interior, glistening from her excitement.
Click.
She took the photo before she could regret it. The sound of the camera shutter made her gasp. She had just taken an explicit photo of her own genitals. Photographic evidence of exactly how wet she was.
What on earth am I doing? she thought, mortified.
She set the phone aside, unable to continue her train of thought as the massager continued its relentless work between her legs. Momo could feel the pressure building in her lower abdomen; she felt her internal muscles beginning to contract.
She hooked her thumbs into the waistband of her black lace panties and pulled them down her legs. They slipped off easily, already drenched. She tossed them aside carelessly onto her rug, something she would never normally do.
The dress was next. She stood up on shaky legs, reaching behind to find the zipper. She lowered it slowly, feeling the fabric loosen around her body. But instead of taking it off completely, she stopped. A different idea crossed her mind.
She lowered the neckline of the dress, exposing only one breast. Pale, full, with a pink nipple that was already hard and erect.
"Oh..." she breathed, looking at herself in the mirror.
She had never truly examined her own breasts like this. The nipple looked different than usual: more swollen and a darker pink. She touched it experimentally with one finger, tracing a circle around the areola.
"Ahh..." the sensation sent an electric shock directly to her crotch.
A completely new experience, she thought, fascinated despite her shame.
She lowered the other side of the dress, exposing her second breast. Both hung free now, large and full, pushed up by the dress still bunched at her waist. Momo covered her face with one hand, mortified by her own reflection. Then, impulsively, she grabbed her phone again and took another photo. Her face was hidden, but her exposed breasts were clearly visible.
I am creating evidence, she thought. Photos that could ruin my future if anyone saw them...
But she couldn't stop. She brought one breast toward her mouth; her natural flexibility allowed her to reach the nipple easily with her lips. Her tongue touched it first, tasting the salty flavor of her own skin. Then she closed her lips around it and sucked.
"Mmmh..." she moaned against her own flesh.
Waves of pleasure traveled from her nipple directly to her crotch. She gently bit the sensitive bud, tasting the mixture of pain and pleasure. The small jolt made her gasp audibly. She did it again, harder this time, actually biting between her teeth.
"Ngh... yes..." she moaned.
This feels amazing, she thought, switching to the other breast.
She sucked and bit both nipples alternately; her large breasts made oral self pleasure surprisingly easy. The combination of the mouth stimulation and the massager still buzzing between her legs was overwhelming. She grabbed the massager again with renewed determination, pressing it firmly against her clitoris with one hand while pinching her nipple with the other.
Bzzzzzz... bzzzzzz... bzzzzzz...
The constant hum filled the room, mixing with her increasingly desperate moans. The combination of sensations was devastating. Momo felt her legs give way, forcing her to sit back down on the edge of the bed.
I need... I need...
She couldn't even formulate the thought coherently. Within minutes, she found herself completely naked. The designer dress was wrinkled somewhere on the floor. Her hair had come loose from the hairstyle, falling in messy black waves over her shoulders.
She lay back on the bed with her legs spread wide, looking at her reflection.
There isn't a trace left of the future professional hero, she thought, examining herself critically.
Her skin was covered in a light layer of sweat that glistened under the soft lighting. Her face was flushed a deep red that extended down to her chest. And between her legs, the sight was absolutely obscene. Her folds were no longer the pale pink from the start; they were now a deep red and swollen. Her inner lips protruded noticeably, glistening from the moisture dripping freely.
A small dark spot was already forming on her silk sheets where her arousal had dripped. Her nipples showed clear evidence of her mouth: the tips a dark red where she had bitten and sucked them, slightly swollen.
I look like... like a...
She couldn't complete the thought. This was what pure desire looked like. And it was beautiful in its absolute vulgarity.
Momo flipped onto her hands and knees, positioning herself so her backside was perfectly framed in the mirror. She looked over her shoulder at her own reflection. Her rear was perfect, round and firm from her training. The cheeks were slightly parted, revealing everything. She could see the moisture coating her inner thighs and her swollen folds. The fluid dripped visibly, forming thin strings.
And above, barely visible between the curves of her butt, was her rear entrance. Small, pink, tightly puckered.
Even in such a vulgar position, she thought, it looks... orderly.
She reached for her phone one more time, twisting to capture the perfect angle. The camera clicked, preserving the image of her exposed and dripping backside. Her internal walls contracted violently at the sound of the click. Then, impulsively, she grabbed the massager again.
I wonder...
She pressed the vibrating head against her rear entrance, pushing gently against the opening. When she activated the vibration, her entire body shuddered.
"OH! Ohhhh...!" she gasped, her voice breaking.
Bzzzzzz...
The sensation was completely new and shocking. The muscle contracted and relaxed involuntarily against the constant vibration, sending waves of pleasure she had never experienced. She couldn't formulate a single thought. She continued the external anal massage, while her other hand reached beneath her body to work her clitoris with desperate fingers.
Schlick... schlick... schlick...
The wet sounds of her fingers mixed with the hum of the massager. The double stimulation pushed her right over the precipice. Her first orgasm arrived without warning. Her entire body went rigid and her back arched violently.
"AHHH! YES! OH, YES!" she cried out, not caring who might hear.
Bzzzzzz... bzzzzzz... bzzzzzz...
The massager continued its vibration against her rear entrance. Momo's hips jerked uncontrollably, pushing back against the stimulation.
"AH! AH! AH!" every movement of her hips tore another cry from her.
But she didn't stop. She pushed on immediately, driving herself toward a second climax. Her fingers worked her clitoris frantically.
Schlick-schlick-schlick-schlick...
The wet sounds accelerated. The second orgasm built with terrifying speed, reaching the crest before the first had even subsided.
"SHIT! Oh, SHIT!" she moaned, using language she had never spoken aloud. "I'm going to... I'm going to...!"
Her internal walls tightened rhythmically. A fluid gushed from her entrance in a sudden spray, soaking the silk sheets.
Splash... splash...
"NGGHHH!" the guttural moan that escaped her throat didn't sound remotely human.
She collapsed forward on the bed, her breasts pressed against the mattress and her buttocks still raised. The massager fell from her trembling hand, rolling aside but still buzzing. Her breathing was harsh and ragged; her body trembled with the aftershocks.
And then, unexpectedly, a third orgasm rippled through her. Smaller, but intense enough to tear another cry from her lips.
"Ngh... ahh... ohh..." she moaned weakly, her voice hoarse.
More fluid dripped from her entrance, adding to the wet stain on her sheets. Finally, after what felt like an eternity, it ended. Momo lay there in the dim light, exhausted. Her body felt heavy and satiated. Her legs were still shaking.
She rolled onto her back, staring at the ceiling. She looked at the massager still buzzing softly, the soaked sheets, and her naked body.
To think all of this started with a single provocative photo, she thought as satiety finally dragged her toward sleep.

Author's Note:
What are your thoughts on this chapter? I'd love to hear from you in the comments. I almost wrote a version where Momo develops a Quirk evolution that makes her produce milk when aroused, leading to some nursing and milking scenes. I ended up scrapping the idea because I thought it might be too ridiculous for most readers.
Anyway, I hope you enjoyed the chapter as it is!
