Becoming Professor Moriarty’s Probability

"........"

As I quietly opened my eyes to the sound of birds chirping, a familiar face came into view.

"Did you sleep well, Adler?"

"... Professor."

Professor Moriarty was smiling gently, making eye contact with me.

Seeing her figure as soon as I opened my eyes, it seemed she had been there for quite some time.

"How long have you been sitting there...?"

"Since you fell asleep hugging me."

"Then, have you been watching over me all night without sleeping?"

"Why sleep? Watching over you is several times more restorative than that."

"......."

"By the way, if it's alright with you, I could do this for about a month."

Her eyes began to quietly shine as she spoke.

What is this, an unspoken warning that she'll stuff me and display me in the house?

… Even if that's true, could I resist?

A chill ran down my spine. If the professor really intended that, there was no stopping her unless I used the ultimate measure of a return right.

If I had succeeded in becoming the professor's assistant this time, it might have been different, but the bold attempt ended in a dismal failure, making the situation even more dire.

"Why such a gloomy expression, Adler?"

"........"

In truth, I had been played by the professor from the beginning, so there was never any hope.

At first, I thought the professor was helplessly succumbing to my momentum, but even that turned out to be an act.

Once the professor started being serious, my stamina was absolutely no match for hers.

- Throb, throbb...

Even now, my lower half, which she had taken ownership of, was throbbing madly.

"Professor, shall we part ways now?"

"Let's, it's getting light..."

So I whispered in a small voice, and she readily smiled and moved her body.

- Creak...

"Ah, just wait a moment."

As I felt the creaking sensation throughout my body and was backing away, suddenly the professor grabbed my hand.

- Swoosh...

Then, with a slightly shy expression, she rubbed her lower abdomen with my hand.

"Feel it for yourself."

- Slosh, blurp, rumble...

"And then tell me about it."

Unknowingly, my cheeks flushed as her soft voice reached my ears.

"How does it feel now that you can't run away anywhere?"

"......."

"You're mine now, Isaac Adler."

At her words, I sweated coldly with a pale face, while Professor Moriarty continued with a dark smile.

"Not that of the feeble detective with a frail body and mind, nor that of the officer who stole the marriage certificate like a thieving cat, nor that of the unknown phantom thief or the murderer filled with blood and slaughter... but entirely mine..."

"Is that so..."

"Heh, heh..."

Her sinister smile began to leak out.

Even though she usually smiles, it's rare for the Professor to laugh out loud, so she must be quite pleased now.

"Professor, there's something serious I want to discuss."

"......?"

"You know, about what happened last night."

Alright, then this must be the right time to strike a deal.

"Let's just say it was a mutual affair under an agreement with you, Professor."

"Hmm?"

"At first, I was the one who aggressively made a move, and then from the middle, you dominated me... Let's just settle it without either of us blushing."

Upon hearing this, the Professor began to tilt her head as if wondering why I would care about such a thing, but it was very important to me.

Game Over Alert!

Because if it were decided that I had been forcefully dominated by the Professor, it would be an immediate game over.

That would lead directly to the route of world destruction.

"You'll agree to this, won't you, Professor...?"

- Sway, sway...

Desperate to avoid that scenario at all costs, I began to plead with her, even swaying the tail that had popped out.

- Swoosh...

"Well, if that's what you really want..."

Observing me quietly, the Professor soon reached out, grabbed my tail, and quietly opened her mouth.

"Ah, thank you..."

- Nomp...

"... Eek!"

As she was about to express her gratitude, suddenly a thrilling sensation transmitted from her spine.

"Indeed, there was a reason you convulsed even when you fainted if I just touched here..."

- Brrrrrr...

"From now on, you listen well to me, Adler."

As she shivered, watching the stars that appeared before her eyes, the professor leaned forward and began to whisper in her ear with a languid voice.

"We'll keep it between us that it was consensual, but publicly, you were raped by me today."

"... Yes, yes?"

"I too am planning a bigger picture. So just as I play along with your plan, you must play along with mine."

With a dazed expression, the professor quietly caressed her cheek and lowered his voice even more.

"If anyone asks about today, just say that I forced myself on you... It's quite simple, isn't it?"

"But, but... what about your reputation, professor?"

"Adler, just say that, and that's all you need to do..."

It seemed that it would harm the professor more than benefit him.

"Do you understand...?"

However, intimidated by the professor's forcefulness, she quickly nodded and replied with a slightly awkward smile.

"Yes, yes... Publicly, I was forced by the professor today."

"Excellent."

Only then did the professor, holding a satisfied expression, release the tail that she had been holding.

"You go ahead. I need to stay a bit longer."

"... Aren't you coming with me?"

"I need to clean up and undo the spells I've cast in Cornwall."

"If that's the case... I suppose I have no choice..."

Following her words, her legs trembling, she quickly began to dress before anything could be changed.

"Oh, and one more thing."

Just at that moment, the professor's relaxed voice pierced his ear.

"From now on, you don't need to bother slipping post-coital contraceptives into my tea or secretly casting ovulation aversion spells on me."

Frozen in the middle of dressing, her actions halted as if the professor could see right into her mind.

"I have already cast a spell to preserve the state inside my belly. No matter what you do, this state will continue indefinitely."

- Slosh, gurgle...

"That means, I can progress the situation whenever I want."

The professor quietly shook her head from side to side as she looked at me.

"If you misbehave even slightly in the future, I will become pregnant immediately."

"........"

"Just be aware of that."

After dropping that bombshell, she waved her hand dismissively at me, who stood there with a blank expression.

"Off you go then."

However, my hands were trembling so much as I buttoned up that I didn't leave the room until about 5 minutes later.

- Squeak...

As Isaac Adler staggered out of the room with his trembling legs, the door closed behind him, leaving Jane Moriarty alone, and a moment of silence began permeating the room.

"... Phew."

In that silence, the professor, still feeling a sense of fullness, stroked her belly as she got up from her seat.

- Click...

Taking a deep breath, she approached the door, firmly locked it, and tightly closed her eyes as she removed the imagined padlock shape from her belly.

"... Hmph!"

And in the very next moment.

"Uh-uh, ughhhh..."

Overwhelmed by the intense sensation focusing on her lower abdomen, Jane Moriarty made a sound as if the wind was knocked out of her and collapsed onto the spot.

- Brrrrrrr...

"This, I didn't know it would be this severe..."

Even in that state, she trembled, wrapping herself up tightly, and muttered in a breathless voice.

"I-I didn't know..."

Finally attempting to regain control, the professor regretted having magically postponed the sensations transmitted to her body, but it was already too late.

"Ah-ah-ah-ah...♡"

- Brrrr, sizzle...

The trembling moans that began to resonate in the firmly closed room of the inn subsided when the sun was high in the sky.

"Uh..."

Meanwhile, at that moment, as Isaac Adler just stepped out of the inn,

"........"

Before he could even take a step, Adler froze solid as he discovered a figure surrounded by black smoke waiting for him.

"There, so this is..."

Soon, a creeping voice began to leak from his mouth.

- Thud, thud...

But Charlotte Holmes, silently watching him, soon quietly began to move forward.

- Swish...

"Uh."

As she reached right in front of Adler, she quietly extended her hand.

"... Ah?"

Adler, who had unwittingly closed his eyes tightly, slowly opened them, feeling the cold and damp sensation beginning in his hand.

"Quietly follow me."

Holding his hand, Charlotte Holmes quietly began to pull him forward.

"Yes..."

Hesitating for a moment due to an inexplicable ominous feeling, Adler soon realized that despite it being morning, the sky was darkened by Charlotte's black smoke and shrank back as he began to follow her.

"But why is your hand so cold and damp..."

"......"

"Ah, it's nothing."
