Becoming Professor Moriarty’s Probability

To reach Cornwall where the client was, we had risen early in the morning, quickly finished our breakfast, and boarded a carriage headed straight for our destination.

"Professor, I believe I advised moderation in your sugar intake."

"... Why bring this up again?"

"Tell me, why wouldn’t I bring this up when you only had milk tea for breakfast, that too stacked with so much sugar that it couldn’t even get dissolved into the liquid anymore?”

Incidentally, the professor avoided meeting my eyes throughout breakfast.

Her demeanour was so different that I felt confused about whether this was indeed the professor who used to emanate such an imposing aura.

"Adler."

"Yes, Professor."

"Aren’t... Aren’t you a bit too close?"

While I observed her from the side, she glanced at me and softly asked a question.

- Slurp...

"Eh?"

Instead of answering, I just licked her neck.

"What are you doing...?"

"You are definitely the professor. No one tastes as sweet as you.”

"Moderation, please…"

Hearing that, the professor quietly murmured, lowering her head.

I should have been this assertive from the start.

Seeing her face turn beet red from embarrassment, I was sure that the professor was weak to someone being so assertive towards her.

Yes, thinking back, hadn’t the professor just stood there dazedly when I mistook her for Lupin before?

Having not met a worthy opponent for so long, she clearly didn’t know how to handle someone who confronted her while asserting dominance.

"But Adler... How long will you keep licking me?"

"Stay still."

"It's ticklish..."

"Just stay still, Professor."

"........"

Perhaps she had always been tough on the outside but soft on the inside.

Either way, this was almost certainly my last opportunity.

I must take maximum advantage of this opportunity to subdue this overpowered final boss. It would make my future dealings much easier.

- Swoosh...

Taking a deep breath for a moment, I stood up and approached the professor.

"Professor~"

Then, with a sly smile, I sat right on her lap.

".......!?"

The professor's eyes widened and her body froze immediately.

- Giut, giut...

"... Pfft."

Watching her, as she began to habitually bob her head from side to side – something she hadn’t done after a long time – I couldn’t help but let out a chuckle.

"Yap."

Then, extending both hands, I grasped her cheeks, holding her head in place. Immediately, I felt the professor's warm body temperature course through my hands, it was pleasant.

"Would you like to wrap your arms around my back?"

"........"

"Or shall I do it?"

In that state, as I softly whispered, I saw her hesitantly reach her arms forward, so I added in a low voice,

"No, let’s just both do it."

".......!"

Thus, the professor and I began staring at each other’s eyes, entwined like a pair of snakes in love.

- Thump, thump...

Soon, I heard the sounds of hastening heartbeat in my ear.

"Ah."

Initially, I thought it was the professor's heartbeat, but upon listening more attentively, I realised it was mine.

... This.

Only then did I realise I had never taken such an assertive role in a relationship before.

Honestly, I've been pounced on a few times, but this was my first time pouncing on someone else.

"... Adler?"

Recalling this, sweat suddenly began trickling down my forehead.

"Why are you making such a face all of a sudden...?"

- Squish...

But before I could gather my wits, the professor's busty and malleably soft chest was pressed against mine.

"Seeing you like this, you're quite adorable."

"Sh-Shut up."

No, I can’t let her take the initiative.

"Don't make that cheeky face. Do you want me to punish you?"

"Ah, and how exactly will you punish me now?"

"........"

"Words alone don't quite capture it, huh?"

While thinking this, I swallowed hard and reached my hand out towards the professor who was shaking her head dismissively.

- Click...

".......?"

As I began to unbutton her clothes, she gave me a confused look.

"What are you doing now..."

"Shh."

Though my hands were trembling with nervousness, I managed to whisper in her ear with as much calm as I could muster.

"I'm going to undress you now."

"........."

"In a carriage that’s fully visible from the outside."

At my whisper, she gave me an alarmed look.

"But I don’t want to show my bare skin to anyone but you..."

"This is your punishment for trying to undermine me."

"Adler..."

"Don't worry. I'll leave your underwear on."

Grabbing her outstretched arm, I pressed it down and whispered in a low voice,

"Let's spend the day like this."

"........"

"It's alright. I'll cast a disguise spell on you so everyone will think you are wearing your usual attire.”

At these words, Professor Moriarty pouted her lips, displeased. Finally, with a completely flushed face, she bowed her head deeply, accepting her fate.

… It seems her mana is still unstable.

By the way, the magic I cast on the professor wasn't a transformation spell but a confusion spell.

I merely unfastened a few buttons of her blouse, but the professor believed that she was being completely undressed by me.

No matter how normal she may appear to others due to the spell, making the professor walk around in just her underwear seemed excessively harsh.

"And here is your collar."

"... A collar?"

"Throughout this case, wear this collar with my name engraved on it."

What I was currently placing around the professor's neck was not a collar, but a jewelled necklace.

Feeling like I hadn't given her any decent gifts, I had purchased this top-quality item with all the dubious sponsorship funds I had received from various places.

Of course, to the professor's eyes, it should look like a dog collar.

"I, I am not your pet..."

"... From now on, you are."

Once I decided to train her, I had to do it thoroughly. If I let my guard down even by the slightest margin and showed any weakness, it would be over for me.

"Hand."

- Whoosh...

The professor, blushing more than ever, quietly placed her hand on the back of my own.

"Good girl."

As I gently stroked her head, the professor's body started trembling again.

… Why does this keep happening?

Watching her, I started to feel a sense of guilt rise up within me.

"Lie down."

- Slide...

It seemed I would have to proceed with this intensive training until the carriage stopped.

Several hours later,

"Uh, um..."

"The air is really fresh here, Professor."

Professor Moriarty, having alighted from the carriage, began looking around with nervousness in her eyes.

"Does it really look normal to other people...?"

"Yes. If it weren't, everyone would be giving you strange looks by now."

"I see... uh?"

"... Even if I pull on the naked professor's collar like this, nobody cares."

Adler gently pulled on her necklace with a natural motion, already accustomed to dominating her during the brief time he had trained her throughout the carriage ride.

"... It's embarrassing."

"I suppose. Anyway, what do we do now?"

As he posed the question, the professor, who was fidgeting and blushing beside Adler, slowly opened her mouth,

"It seems our client is quite cautious. The brief only mentioned to come to this address and we would know what to do once we reached here.”

"... Isn't this too dangerous then? It could be a trap, and our identities might get exposed."

"I've already had my people scout the area. No dangers or suspicious individuals were spotted."

"......."

"That’s all I have to re-report."

After she finished speaking, she stared blankly at Adler, who began fumbling in his pocket with a smirk.

"Here you go."

"Th-Thank you."

Eventually, pulling out a sugar cube, he extended his hand towards her, and she, as trained in the carriage, cautiously started licking the cube in his hand like a good puppy.

"........"

Adler’s eyes narrowed as he looked at the future Queen of Crime— someone, who would be so notorious that no one would even dare to as much as look at her with anything but subservience.

"Help, help!!!"

"".......!?""

Suddenly, a panic-stricken scream began echoing from the quiet roadside where they were standing.

"They're all crazy... crazy!!"

Exchanging glances, Adler and Professor Moriarty slowly began moving towards the originator of those screams.

.

.

.

.

.

"Ah, um..."

Thus, the two found themselves walking towards the nearby mansion.

"This is..."

"........."

As soon as they entered the yard, they stopped in their tracks, staring blankly through the windows at what was taking place inside the house.

"Ah... Uh..."

- Creak, creak...♡

"Masters, please come to your senses..."

For some reason, everyone inside the house had bizarre expressions and were engaged in unspeakable acts.

"Come to your senses..."

"... Huh?"

Eventually, even the maid, who seemed to be the source of the screams and was struggling inside to stop the people, became dazed, and Adler watched her with an utterly perplexed look.

"I, I want to join in too."

"... This is not the Devil’s Foot I am aware of though?”

As he muttered to himself and stepped back, Professor Moriarty, who had been bowing her head behind him, suddenly flashed a bone-chilling smile and chimed in.

"Of course, it isn’t."

"Hmm?"

"... It's nothing, Adler."
