Just Stay Still. I'm Really Having a Hard Time Holding Back.
My heart pounded.
Thump.
Thump thump.
It was racing wildly.
Thump thump thump.
Regrita’s heart was beating like it had gone completely insane.
―I didn’t wear anything on top because there wasn’t any, but… I did wear something down below, Princess.
Ever since she heard those words, this had been happening.
She had clearly suppressed it so well with magic. She had used a full twenty percent of her power just to keep her emotions in check….
Pop.
The transformation magic unraveled.
Two large, imposing horns sprouted from Regrita’s head—massive, elongated ones that were the very symbol of the demon king’s bloodline.
“Huh…?”
Melly looked startled.
She was probably wondering why Regrita’s transformation magic had suddenly come undone.
And of course, the reason was obvious.
‘This is seduction, right? It has to be seduction, doesn’t it? She’s been walking around with me this whole time without wearing underwear, so how could this not be seduction? I even showed it so obviously… and she deliberately didn’t wear any….’
That was exactly what Regrita was thinking.
Regrita took one step closer to Melly.
“…Just a moment, Princess.”
Melly stepped back.
Regrita followed with another step.
Eventually—
Thud.
Melly found herself backed against the wall.
Crack. Thud.
The magic suppressing her heartbeat began to dissolve, one strand at a time.
With every thread that came undone, Regrita’s reason drifted farther and farther into the distant cosmos.
“Haa… ha….”
Rough breaths escaped from Regrita’s lips.
“Princess. Princess! Snap out of it, Princess!!”
Cornered against the wall, Melly squeezed her eyes shut and flailed her arms wildly.
Does Teacher know? Regrita thought. The cuter you act, the harder it becomes for me to control myself.
This couldn’t happen. Teacher might hate her for it….
Even though her body understood that, it refused to stop moving toward her teacher.
Tap.
“H-huh? Princess?”
Before long, Regrita planted her palm against the wall beside Melly’s ear.
Melly was now perfectly trapped within Regrita’s embrace.
“P-Princess… please come back to your senses….”
“Huu… haa….”
If you don’t want me to lose control, then stop looking up at me so adorably.
She wanted to say it, but the emotions she had been desperately holding back had already burst free. All Regrita could manage now was ragged breathing.
“Princesssss….”
Realizing how serious the situation had become, Melly whimpered and tried to squirm out of Regrita’s arms.
But there was no way the frail Melly could possibly escape Regrita’s hold.
Instead, every time she struggled, different parts of her body brushed against Regrita.
Just before her reason completely snapped—
Regrita summoned every last ounce of superhuman willpower she possessed and uttered a single sentence.
“Hic?!”
She hadn’t meant to sound scary.
But her voice had dropped so low that Melly flinched in fear.
Still, Regrita could no longer endure it.
“Haaum.”
She tasted Melly right then and there.
* * *
“Just stay still. I’m really having a hard time holding back.”
“Hic?!”
Was it because I tried to force my way out?
The princess’s voice had dropped threateningly, like she was angry.
O-oh no. If things kept going like this, the future didn’t look good at all!
The princess’s breathing was ragged.
Both of her massive horns had fully emerged, and a faint blush colored her face.
Melly had never experienced anything like this before, but even she could tell there were only two possible futures from here.
One was to be toyed with in every way imaginable and turned completely into the princess’s plaything.
The other was… well, to be toyed with in every way imaginable until she became the princess’s plaything.
…What should she do?
In this situation, the only thing that could possibly be useful was her brain.
She was just putting her shrunken mind into overdrive when—
“Haaum.”
“Hyaat…!?”
The princess suddenly lowered her head and took Melly’s left ear into her mouth.
Nom nom.
Soft, warm flesh massaged her ear.
Hot breath tickled the inside of her ear canal.
The intense new sensation nearly drove her out of her mind, but—
―Just stay still. I’m really having a hard time holding back.
Realizing this was the princess squeezing out the very last shred of her sanity, Melly clenched her teeth and endured.
The princess’s nom nom attack didn’t stop until Melly’s ear was completely wet and slick.
“Pwah….”
It was only after about five minutes that the princess finally released her ear.
Melly had been worried whether an ear that had spent five whole minutes inside the princess’s mouth would still work properly, but thankfully, she could still hear just fine.
“Huu… haa….”
The princess pulled away the hand that had been pressed beside Melly’s head and took several steps back.
After catching her breath and wiping the saliva from the corner of her mouth, she spoke.
“…I’m sorry, Teacher. I’m truly… sorry.”
Shrrk.
The enormous horns slowly faded away again.
That meant the princess had regained her senses.
Melly was more relieved about that than she was about getting her ear back.
At least now she wouldn’t have to suffer anything worse.
“Ah…”
“Princess!”
After breathing heavily a few times, the princess suddenly staggered.
Melly quickly caught her around the waist just as she was about to fall backward.
Tap.
…It was frustrating that simply grabbing her wouldn’t have been enough—she had to hug her tightly just to keep her from collapsing.
But what could she do?
Her transformed body was far too weak and delicate.
The princess already seemed to be at least twenty centimeters taller than her. If she had tried to hold her up with just her hands, they both would have toppled over.
“Goodness… Princess, are you okay?”
Honestly, her own soaking wet ear was probably in the worst condition, but as the princess’s tutor, Melly’s first priority was checking on her student.
However—
“Suu… suu….”
The princess, who had been perfectly fine just moments ago, was now fast asleep in her arms as if she had fainted.
To an ordinary person, it might have looked like sudden narcolepsy.
But Melly was no ordinary person—she had specialized in the theory of magic synthesis.
From her painful experiences grinding away in the research lab, she could tell exactly what was happening to the princess right now.
“…Mana backlash?”
It seemed the princess had temporarily lost consciousness due to a mana rebound.
There were only two situations that caused mana to flow backward like this.
Either the person had squeezed out an excessive amount of mana, or some kind of restriction planted inside their body had collapsed.
In Melly’s opinion, the latter seemed far more likely.
A mage of the princess’s caliber wouldn’t suffer mana backlash just from overexerting herself.
It was probably because of some self-imposed restriction….
But what kind of restriction would cause her to collapse like this?
As she thought about it, a chill ran down her spine.
“No way…”
Surely the princess hadn’t cast some ridiculous spell to suppress her own heartbeat whenever she looked at her, right?
Melly had known from their very first meeting that the princess’s gaze toward her was anything but ordinary.
But if those feelings were so intense that the princess couldn’t endure them without doing something like this…?
By wrapping mana around one’s heart and pressing down hard, it was possible to regulate emotions to some degree.
Of course, that was only theoretically possible. It required a level of mana control that ordinary mages couldn’t even dream of.
It was such a dangerous spell that it could cause the heart to explode, so no one even attempted it.
Unfortunately, the princess was one of the few people in the world capable of actually performing that theoretical magic.
“Oh dear…”
Melly unconsciously clutched the back of her neck.
No matter how she looked at it, the reason the princess had fainted seemed to be the restriction she had placed on her own heart.
“What were you thinking? What on earth were you thinking?!”
Slap, slap.
She patted the princess’s cheek—though it was so light it was more like gentle tapping.
Anyway.
The reason Melly was laying hands on the princess, however faintly, was simple.
“What if you had died?!”
If things had gone even slightly wrong, this wouldn’t have been a simple faint—it could have been fatal.
That was how dangerous and difficult it was to cast magic directly on one’s own heart.
If the princess had died here, what would that make her tutor?
A cute shark who seduced the princess to death?
Ugh, no! Absolutely not!!
It was truly the worst possible scenario. Just thinking about it made her shudder.
“Mmm…”
“Are you awake, Princess?”
“……”
When the princess furrowed her brow, Melly thought she was waking up.
But she was just shifting uncomfortably in her sleep.
Ah, right.
Even unconscious, standing up must have been uncomfortable.
Melly immediately laid the princess down properly on her bed.
She briefly wondered if she should perform CPR, but the princess’s breathing was normal, so she stopped.
Phew… at least it wasn’t the worst outcome.
She had only fainted and didn’t seem to have any other complications.
“Haaa…”
After tucking the princess in with a blanket, Melly let out a tearful sigh.
What on earth had just happened in such a short time…?
She had simply been getting fashion advice from the princess.
Then suddenly the princess got interested in whether she was wearing underwear, backed her against the wall, and took her ear into her mouth.
And then she staggered and collapsed.
…She couldn’t figure out where any of this was her fault.
Was it because she hadn’t been wearing a bra beforehand?
She should have been wearing one! She should have!
Feeling unfairly upset, she poked the princess’s cheek.
Well, it wasn’t really a poke out of fear—it was more of a gentle prod.
She didn’t want the princess to wake up and cause more trouble.
“Ugh… seriously, Princess!”
She was angry and felt wronged, but getting mad at someone who was unconscious wouldn’t get her an apology.
Knowing that very well, Melly stopped wasting energy and headed to the bathroom.
Click.
Once inside, she stared at the shark-like figure reflected in the mirror.
“…It’s way too wet.”
Had this shark only gone swimming on one side?
Only one ear was completely soaked.
“Sigh… I can’t exactly ask her to dry it for me when she wakes up.”
She scrubbed her ear thoroughly, which was covered in the princess’s saliva.
Some soap bubbles got in her hair in the process, so she washed her hair too.
While she was at it, she decided to just take a full shower.
Somehow she ended up washing her entire body. Thanks to that, she felt much better.
When she came out of the bathroom, the large bed immediately caught her eye.
Since the only piece of furniture in the room was the bed, that was only natural.
She shook her head vigorously to dry her hair, then climbed onto the bed.
The princess was still sleeping soundly with an innocent, unknowing expression.
“…You look so pretty when you’re sleeping like this.”
She briefly considered developing a permanent sleep spell and casting it on her all the time, but she had no intention of turning their beloved Princess Regrita into a sleeping beauty, so she gave up on the idea.
Instead, she grabbed the princess’s lips with her index finger.
“Was it this naughty mouth that dared to eat Teacher’s ear? Hm?”
She gently tugged on the princess’s soft lips.
As she had said before, she was careful not to wake her.
After pulling on them a few more times, she flopped down beside the princess.
“Princess, I’m sleeping here tonight too, so you can’t do anything weird, okay?”
She wasn’t sure if a mere tutor was allowed to sleep beside a princess, but she had a perfectly reasonable justification.
“I’m the one who got sexually harassed out of nowhere, and I’m the one who took care of you afterward, so you should at least allow this much. Even you have to admit that, Princess.”
Besides, this was her room and her bed.
If she had to sleep on the floor just because the princess was lying on the bed, she was confident she could cry enough tears to flood the room.
“And seriously… just you wait until tomorrow morning, Princess. I’m really, really angry, so you’d better get on your knees, reflect on what you did, and prepare to be scolded…”
Blink. Blink.
Maybe it was because too many exhausting things had happened.
Her eyes kept trying to close.
“And it’s dangerous, so please don’t use weird magic on your heart anymore…. Do you understand?”
Her voice grew quieter and quieter.
“I have a duty to raise you into a splendid Demon King… so please don’t do anything dangerous… I’m begging you…”
Eventually her eyelids fell shut and her voice faded away.
She drifted off to dreamland while imagining fifty-three different ways to give the princess a good scolding tomorrow.
The truly unfair part was that even in her dreams, she still lost to the princess.
