Becoming Professor Moriarty's Probability

0% “Holmes.”

“........”

“Get up already.”

Charlotte, who had been lying dazed on the bed, snapped out of her stupor at the soft voice coming from beside her.

“Sister...?”

“I planned to wait until you woke up, but since you were taking so long, I had no choice but to wake you.”

Charlotte blinked, her gaze darting around the room in confusion.

“Uh...”

When she turned to see the familiar face next to her, her expression froze in a mix of bewilderment and disbelief.

“... Sister?”

“Hehe.”

It was none other than her sister, Mycrony Holmes, sitting naked on the bed, a mischievous smile playing on her lips.

“Ho-How are you here...? No, more importantly, why are you naked?”

“Oh my, is that really what matters right now?”

“... What?”

Charlotte, still trying to make sense of the situation, shot her sister a confused look. Sensing something off, she tried to lift herself up from the bed.

“What do you mea... ugh?”

However, as soon as she attempted to rise, a sudden moan escaped her lips, and she collapsed back onto the bed.

- Clink...

“Wh-What the hell...? What is this?”

Frowning in discomfort, Charlotte buried her face into the sheets. It was only then that she realised her body was bound by greyish-black chains, prompting her to ask with a startled expression.

“This is a sealing spell I specially crafted.”

“... What did you say?”

“It was designed to neutralise terrifying beings like you and the professor.”

Mycrony Holmes explained matter-of-factly, her tone calm and almost cheerful.

“The government even funded me with 1,000 mana stones for this, so escaping it will be nearly impossible for you two.”

“Shit...”

“Oh, and by the way, your boyfriend was being far too rough, so I had to put him to sleep for a bit.”

Glancing briefly at the professor, who was also chained and unconscious, Mycrony muttered before turning her gaze to Adler, sprawled limply behind her. A sinister curl formed at the edge of her lips.

“Being raped can be fun, but... I do prefer being the one doing the raping.”

“Wait, hold on...”

“Well then... ngh.”

Positioning herself atop Adler, who was still unconscious, she shyly straddled his lap as though sitting on a chair, facing Charlotte.

- Slurp...

“... Holy fuck, this is insane.”

Even unconscious, Adler’s cock remained rock hard, pressing against her slit. Mycrony shuddered involuntarily, her expression flickering between astonishment and arousal as she murmured to herself.

“I’ve only ever watched through scrying before, but... now that I’m up close, the thickness, the girth... it’s so much more incredible...”

“S-Stop it.”

“... Hmm?”

Meanwhile, as Charlotte watched that sight while breaking out in a cold sweat, she hurriedly opened her mouth as Mycrony began to move her body.

“Stop it...”

“Mmm... I’m not sure what you’re talking about?”

“Damn...”

“Wanna explain a bit more clearly?”

But despite her desperate gaze, Mycrony, with a slightly flushed face, grabbed Adler’s cock, hoisted it up, and brought the throbbing manhood to her pussy.

“Don’t put it in!!!”

After watching that sight with a pale expression, Charlotte finally couldn’t hold back and shouted.

“... But I want to.”

However, as if she was waiting for those words, Mycrony, with her mouth to her ear, mercilessly pushed the head of Adler’s cock into her pussy.

“Don’t! Don’t!! I said don’t, you fucking bitch!!!”

“Oh please. Calling your sis a fucking bitch is too much, don’t you think?”

“Just try sticking it in further!!! I’ll kill you!!! I’ll fucking kill you!!!”

At that sight, Charlotte, who was bound in chains, began twisting her body as if having a seizure.

“That’s exactly it...”

Unable to hold back any longer, Mycrony muttered in a trembling voice, and suddenly her eyes sparkled slightly.

“That’s the face I wanted to see... Heek.”

The next moment, her lower mouth completely swallowed Adler’s cock and shed red blood.

“”.........””

And then, heavy silence descended on the scene.

- Tremble tremble...

In that silence, Mycrony, who until just before had been leisurely teasing Charlotte, showed a stiff expression as her lower body trembled visibly.

“....? ....!?”

Soon, her face began to turn more and more pale.

What the hell... is this?

Although Mycrony had pursued all kinds of stimulation for over 20 years of her life, the sensation she just felt spreading through her whole body from her spine was on a different dimension from anything she had ever experienced before.

My head... My mind is going blank...

As a result, the leisurely momentum from before disappeared without a trace, and Mycrony was even breaking out in a cold sweat with Adler’s cock inside her pussy, her head hanging low.

I can’t... think of anything.....

“Mmm...”

“........!”

“Miss Mycrony...?”

She flinched in surprise at Adler’s dazed voice and breath reached her ears out of the blue.

“What... Why are you sitting on top of me...?”

“W-Wait. Don’t move...”

- Haaah.

“Chomp...♥︎”

After looking at Mycrony with half-closed eyes, Adler suddenly bit into the nape of her neck.

- Nibble nibble...

“Hic? Eek?”

Soon, as Adler began to nibble on her flesh, Mycrony started trembling with an utterly terrified expression.

- Swish...

Then, to top it off, Adler wrapped his arms around Mycrony’s waist, which was thin and slender, unlike her plump breasts.

“Wait, just a moment... I, I was wrong, so...”

“... Hey.”

Sensing an inexplicable chill from him, Mycrony began muttering as if pleading.

“Are you prepared?”

Adler, slightly lifting his head, whispered in her ear and gently lifted Mycrony with his hands.

“...Wait. Hold on!”

Mycrony, realizing what he was trying to do, raised her voice while flailing about.

- Squelch......!

“......!!!”

However, as Adler mercilessly grabbed her waist and pressed down, shoving his cock in as deep as possible, Mycrony’s eyes momentarily turned white and her whole body went limp. She was so shocked that she could not even voice anything.

“Oh, ooh...”

“What, did you cum just from that?”

Then, as her body began to spasm sporadically, Adler chuckled and caressed Mycrony’s lower abdomen.

“... But I can’t go easy on you.”

He flipped over Mycrony, who was shivering with her head lowered, into a plausible doggy-style position.

“........”

Unfortunately, Mycrony’s completely dishevelled face ended up buried between Charlotte’s legs who was watching the scene unfold with an utterly blank expression.

“Holmes, you seeing this, right?”

For Adler, who was half-intoxicated by the professor’s aphrodisiac, the situation was hardly something for him to consider.

“Your sister seems to like my cock more than you.”

“.......”

“Isn’t that right, Mycrony?”

As he grabbed Mycrony’s hair and lifted her head so Charlotte could see her expressions, he casually asked.

“... Yesh.”

Vividly feeling her brain melting from pleasure, Mycrony, drooling profusely, began muttering while looking at Charlotte, who was staring down at her with dead eyes.

“Sorry, Holmes...”

“.......”

“But your boyfriend’s cock... is seriously amazing...♥︎”

Mycrony, who at some point had even interlocked her fingers with his, continued to let out cries of intense pleasure.

“... So can your dearest sis borrow it for a bit?”

With those words, she buried her face in her sister’s pelvis and began convulsing again.

“I’ll cum soon.”

“Yes, yesh...”

“Get pregnant like this in front of your sister watching.”

“... Th-Thank you.”

She vividly felt a chill in her lower abdomen at Adler’s cold voice coming from behind.

- Twitch, twitch...

“........♥︎”

And so, holding her sister’s hand and enjoying her lifeless gaze, Mycrony received Adler’s seed.

.

“Uhh...”

My head felt foggy.

Just what on Earth happened when I had blanked out?

- Slurp, slurp...

“.......?”

Staring blankly at the pristine ceiling for a while, I somehow forced my heavy head to lift at the sound coming from below.

“... What the...”

And there, a dreamlike scene unfolded before my eyes.

- Munch, munch...

- Lick...

“What the hell.”

There was Charlotte and Mycrony, stark naked, each with one of my balls in their mouths, playing with them, while the professor was diligently licking my cock in between them.

“... Ah, Adler. You’re awake?”

What kind of situation was this?

“No, no. I hypnotised him earlier, so he should be in a sleep-like state all day.”

Seeing that my vision was quite blurry, could this be a dream?

“You didn’t have to go that far, sister.”

“But you see, when he loses himself under the influence of narcotics or alcohol, he goes wild. Considering all the things he’s done so far, he ought to obediently let us have our way with him.”

“... That’s true.”

Surely, it must be a dream.

There’s no way those three would be sitting together harmoniously, sharing my cock and licking it.

But why was I even here?

Why was my mind so foggy, as though shrouded in mist, making it impossible to think properly?

“... That aside, his cock’s gotten hard again.”

“Great. So, what position shall we try next?”

“Sister, just shut up and do as you’re told...”

But just as I began questioning these absurd facts, my consciousness grew hazy once again, and the scenery before me suddenly shifted.

“Ugh...?”

- Creak, creak...

In the new scene, I found myself in a doggy-style pose, Charlotte on all fours as I penetrated her while Mycrony was straddled on top of her as she leaned in to share a passionate kiss with me.

“Sis... you’re so heavy...”

“Slurp... Well, I do have a bigger chest, don’t I...”

Yes, this had to be a dream.

Considering the way the scenes kept changing in a flash, I was certain.

After all, I often had erotic dreams since I was young.

The kind of vivid dreams that made me have a hard-on when I woke up.

But, does just dreaming really leave your body feeling sore?

... Where’s the professor?

Feeling an inexplicable sense of dread, as though I was about to realise something I shouldn’t, I desperately tried to shift my thoughts. I began scanning around for the professor, who was absent from my field of vision.

“... Hmm, ah.”

And soon enough, I discovered her.

The professor, eyes softly shut, was meticulously licking my rear. She was giving me a rimjob.

This can’t be real.

For a moment, I really thought this was an absurd scenario, but I immediately accepted the situation.

This was a dream, after all. Anything absurd could happen.

Again... my head...

As I reached that conclusion, my head throbbed once more, and a hazy feeling began to wash over me again.

“Fuck... this was supposed to be my bed... Why am I going through this...”

“Hehe, but isn’t it nice to play with your sister after so long?”

“... Shut up.”

What came into my view next were the Holmes sisters, pressing their breasts together, enveloping my cock, and performing a double boobjob.

- Creak, creak...♥︎

Whether it was the unexpected synergy between Mycrony’s voluptuous chest and Charlotte’s petite breasts, my cock swelled rapidly in no time.

- Shudder...!!!

And soon after, my cock predictably spewed its seed, soiling their chests.

“Uhh...”

Watching this in a daze, I suddenly felt the sweet, creamy milk from the professor’s breast flow into my mouth as she pressed it against my lips, making me close my eyes in comfort once more.

“””Blehh...”””

When I opened them again, the three women were kneeling before me – or more accurately, before my cock – with their tongues extended.

“... Ah.”

The sight of my cock resting on the three distinct tongues, each offering a unique sensation, was more lascivious than anything I had ever witnessed.

... It’s definitely a dream.

But seeing the three women so harmoniously pressed against one another with their tongues touching was an impossibility, which only affirmed my belief that this was a dream.

If it’s a dream, then... well...

Finally at ease, I decided to indulge in this situation just a little.

- Tap, tap, tap...

The moment that decision was made, the Holmes sisters began gripping and stroking my shaft with their hands, while the professor took hold of my balls, kneading them gently.

- Slurp... Slurp...

Not long after, I spilt every drop of my essence onto their soft tongues.

... This is ridiculously erotic.

The next moment, the women, their eyes lit with desire, began savouring my semen from each other’s tongues, swirling their tongues together as they did so.

This... this is an erotic dream... right...?

Staring uneasily at the oddly realistic scene, I gradually succumbed to the fatigue washing over me and closed my eyes once more.

For some reason... it feels like my life force is slowly ebbing away...

Afterwards, fleeting images passed through my mind: the women lying side by side on the bed, their backs pressed against each other.

To scenes of them imitating dogs and cats with their bellies exposed, betting on who I’d choose first.

The scenes then shifted to them taking turns riding me in a cowgirl position while simultaneously licking my ears from both sides.

But by then, I could no longer do anything.

The ending is near.

“.........”

The system message that had appeared before me earlier— I dismissed it as nothing more than a by-product of this erotic dream, clinging desperately to my mental defiance.

“Adler, you’ve been conscious for a while now, haven’t you?”

“Open your eyes. I’d like to have you while you’re fully awake.”

“... If you don’t open them, I’ll just keep raping you until you die.”

Feeling that all-too-familiar, numbing sensation for what seemed like the umpteenth time, I stubbornly kept my eyes shut.

“”Adler?””

“Adler, my dear?”

I can’t hear you, can’t hear you, can’t, cant...

Muttering this mantra internally, I soon fell back into the deep darkness once more.
