Becoming Professor Moriarty’s Probability

As the hotel room door opened without any trouble, a boy and a girl entered inside.

A thick silence lingered in the air of the room.

“… Ah, the ambience is rather vibrant.”

“Th-That’s right, isn’t it? Since it’s a love hotel…”

Charlotte, slightly flustered by the pink hues filling the room, turned her head with a cold gaze after hearing Adler’s composed remark.

“Mr Adler, you are accustomed to places like this, huh?”

“Uh, well…”

“Never mind.”

“Now I feel a bit more comfortable.”

“Um, Miss Holmes…”

“H-How about we take a shower first?”

Charlotte, who had been moving further inside with a satisfied expression, quietly turned her head upon hearing Adler’s timid question.

“Alright.”

“Ye-Yes… Then… Miss Holmes first…”

“No, let’s shower together.”

“… What?”

Uttering those words, she began pulling Adler by the hand. Their destination— the bathroom attached to the hotel room.

“Um, um…

“What’s the problem?”

As Adler, being dragged along by her, muttered in confusion, Charlotte posed a question with a puzzled look on her face.

“We’re going to have sex soon anyway, right?”

“And you’re worried about showering together?”

Adler could not muster any objection to her words.

“Follow me.”

“Yes…”

Given Charlotte had already taken half control over his body, opposing her was out of the question.

“Um, excuse me?”

Thus, Adler, his devil’s tail drooping sadly behind him, followed Charlotte.

“It doesn’t seem like we’re heading towards the bathroom…?”

He once again questioned Charlotte with a flustered voice as she was heading towards the bed on the opposite side of the bathroom.

“… I said we’d shower together, I never said we’d shower right now.”

“Wh-Why not…?”

Then, with a dark smile, Charlotte replied.

“If we’re going to get sweaty anyway, it’s better to have sex first and then shower, right?”

“… Bu-But.”

“Ah, don’t worry about my smell. I took a bath and sprayed perfume before meeting you.”

“S-So, you were planning to pounce on me from the start?”

Adler, looking slightly fearful, murmured in a low voice as he turned around.

“Since Miss Holmes has showered already, I’ll quickly go and shower alone…”

“That’s okay.”

“What?”

But then, Charlotte murmured behind him in a barely audible voice.

“… I don’t mind if you don’t shower.”

“That’s even more arousing.”

Adler’s thought processes slowly began to break down after hearing that.

As soon as Isaac Adler entered the bathroom, he quickly stripped off his clothes and leapt into the bathtub. Turning on the tap, he sat down with a blank look in his eyes, lost in thought. 𝐫

Is there really no way to escape?

- Jizik… Jizik…

I can’t even send a message… This is driving me mad, dammit.

Charlotte Holmes’s dark aura filled the hotel room, acting as a jammer, blocking any attempt to send a distress signal.

… Now that I think about it, I can’t even use mana, can I?

Moreover, due to being controlled by Charlotte, Adler was unable to use his mana properly.

“Ugh…”

- Splash…

Sweating coldly and struggling to keep his stiffening mind active, Adler, startled by the sound of water in front of him, opened his eyes with a puzzled expression.

And soon, his eyes widened in surprise.

“Why are you so startled? We agreed to shower together, didn’t we?”

“Ah, that…

“Since you’ve already entered the bath, I might as well join you.”

Charlotte, who had been wearing only panties, had already entered the bathtub before even finishing her words.

“… Eek.”

“And… your penis is as big as ever.”

“I was really surprised when I first saw it…”

Adler gasped, feeling her smooth, wet back and soft buttocks against his abdomen. When he heard her murmurs, he looked down at he with a puzzled look.

“H-Have you… seen mine before?”

“… Yes.”

“Wh-When?”

Charlotte calmly answered his question.

“When you were hospitalised last time, I took a little peek.”

“It’s really different from what I’ve seen in the books. Whether yours is particularly large, or the books are wrong, I’m not quite sure…”

“Uh, pardon?”

Adler, momentarily startled, hurriedly interrupted her.

“Is… Isn’t that a crime? A sexual offence, Miss Holmes?”

“Is it?”

“If the London’s hope behaves like this… You are supposed to be the symbol of justice guarding London…”

“I’m not sure how many times I have to say this but…”

Then she quietly stared into Adler’s eyes and spoke.

“You have no rights.”

“Therefore, even if I secretly took out your cock while no one was around, briefly scrutinised it and then lightly touched it with my tongue, and naturally held the hot organ in my mouth… it’s not a crime.”

Adler’s gaze became vacant. He was at a complete loss for words.

“… You didn’t actually do that, did you?”

“That was just a simple rehearsal.”

“Wait…”

“The real show starts now…”

With that, she covered his mouth with her hand, turned her body around, and bowed her head down.

“… Six months ago, no one could’ve imagined something like this, right?”

Charlotte, who was about to lick Adler’s penis, suddenly burst into a self-deprecating laugh and muttered.

“I, who despise men, to think I’d be licking a penis…”

- Twitch…

“Oh, do you like hearing such things?”

The next moment, as Adler’s erect rod twitched slightly, Charlotte looked up at him with a frigid smirk.

“Pervert.”

“I can’t help but think, isn’t Miss Holmes the pervert here… Ugh.”

As Adler’s face turned bright red and he mumbled, he halted his words and moaned the moment Charlotte’s tongue touched the tip of his penis.

- Lick, lick…

She gazed at him intently as she licked his glans with her tongue, then quietly kissed the opening at the top.

“… In the past, just brushing clothes with a man would make me uncomfortable all day.”

- Squirm…

“Now, kissing the tip of your penis is making my body heat up…”

She murmured overtly lewd remarks, closed her eyes, and slowly began swallowing Adler’s twitching member into her mouth.

“… Huk, hakhg.”

However, halfway through, tears welled up in her eyes suddenly, and she started gagging on his massive length.

“Ugh…”

Charlotte’s eyes slightly panicked, realising that his penis had grown twice as large as it had during her previous practice. This was a fact that she had not calculated at all.

“Gulp…”

“Um, hey…?”

“Mmm…”

But her hesitation was momentary. Squeezing her eyes shut again, she forcibly pushed his massive member down her throat.

Thus, Adler’s huge dick practically packed her whole throat, and Charlotte’s face dug into Adler’s lower abdomen.

- Gulp…

“Wait…!”

Her oesophagus began to spasm, and the vibration quickly pushed Adler to his limit, prompting him to urgently start pushing her away.

- Clench…

“…..!”

But just before his penis could be pulled out of her mouth, Charlotte stretched her arms forward and embraced Adler’s waist.

- Brrrr, brr…

“Ugh…”

It did not take long for Adler’s thick shaft to spill out ropes of cloudy semen directly into her mouth.

- Brrrrrr…

No one knew how much time passed just like that.

“Haah, haah…”

“Aaaaa…”

Charlotte, having just pulled Adler’s cock out of her mouth while breathing heavily, silently opened her mouth to show the cum she had gathered inside her mouth.

- Drip…

Then, she spread her hands and slowly began spitting the liquid out.

- Lick, lick…

As her palms filled with Adler’s semen, she quietly looked at it, closed her eyes, and began licking it up delicately like a cat enjoying milk.

- Twitch…

At that, Adler’s cock revived in an instant.

“… Still lively, huh?”

“Uh…”

“It’s quite different from what I’ve read in books.”

Tilting her head and murmuring, Charlotte climbed back on top of Adler’s cock just like before, pressing her back against his belly.

- Swoosh, swoosh…

She then slipped his cock inside her panties, held hands with Adler, and began slowly grinding her ass against his pelvis.

“Wa-Waait…”

“No.”

Adler, feeling the erotic pressure of Charlotte’s slippery back and buttocks, muttered with a trembling voice, but Charlotte’s firm voice cut through immediately.

“How long do you think I’ve waited for this moment?”

“Enough already…”

“Stop talking nonsense and just come.”

At that moment, Charlotte whispered into his ear, slightly tilting her head.

“It’s my first time; so we need some lubricant.”

- Squirt…!

Burying his head in the nape of her neck, Adler hugged her tightly and came once more.

- Gush, gurgle…!

Seizing the moment, Charlotte, licking her lips, pressed her butt against his pelvis as much as possible.

“Miss Holmes…”

Adler, having stained Charlotte’s white panties and ass with his semen, murmured with a whispery voice while still burying his head in her neck.

“I… I think I came too much at once…”

“What?”

“I-I’m feeling dizzy…”

Charlotte silently turned her head towards her after hearing his words.

“So… maybe we should rest for a bit…”

“… Ah, don’t worry. That’s normal.”

She rubbed her cheek against his, smiling bitterly, while Adler looked puzzled.

“Seems like the drug in the bath water is kicking in.”

“Pardon…?”

“It was hard to get. We must enjoy it thoroughly, right?”

As Charlotte continued calmly, Adler started sweating profusely.

“I’ve taken so many drugs that I think I’ve developed a tolerance. Except for a bit of heat inside me, I feel rather normal…”

“I asked you to be gentle…”

“If you keep saying such arousing things, I might end up slipping your penis inside me without realising it.”

“That’s… that’s real crime…”

“… I’ll say it one last time.”

Listening to the words Charlotte said with the corner of her lips curling up, Adler soon lost consciousness.

“You have no rights here.”

“… Beast.”

.

.

.

.

.

An unknown amount of time had elapsed…

“Ah, you’re awake?”

Feeling his body grow hot, Isaac Adler groggily opened his eyes to a surprising scene.

“I was just about to put it in, good timing, huh?”

Charlotte Holmes, who had somehow dragged him to the bed, was straddling him, her lips enveloping Adler’s member.

“Um…”

Adler tried to speak, but—

- Sssk…

Before he could form a sentence, Charlotte bit her lip slightly and thrust her hips down.

- Brrrr…

Unknowingly raising his arms to cover his eyes, Adler began trembling ever so slightly from the fiery sensation he felt in his lower body.

“Haah…”

Similarly, with eyes closed lightly, Charlotte’s pussy quivered from the feels.

“Amazing…”

Eyes now narrowed, she murmured with a wicked smile while looking down at the man beneath her with eyes overloaded with lust.

“… I think I came a little just by putting it in.”

The detective, who had just lost her virginity, intermittently released her juices as she felt Adler’s thick rod violently probe the sensitive spots inside her depth.
