Becoming Professor Moriarty’s Probability

"... Stay still, Adler."

"This... this is inappropriate, isn't it?"

Adler, his arms grabbed by the professor, leaked cold sweat from head to toe as he muttered in a shrinking voice.

"I-I thought I told you, Professor. You're the servant, and I'm the master..."

"Yes, I heard you clearly."

"But what is this now then..."

"You've overlooked something."

Then the professor answered him with a smile colder than arctic frost.

"My curse is that every crime committed by my hand becomes a perfect crime."

"So now, even if I disobey you and fuck you like a dog, no harm will come to me."

Understanding what she said, Adler opened his mouth and looked at her with a vacant gaze.

"Because rape is also a crime."

"........"

"Isn't that right, Adler?"

Finishing her remark, Professor Moriarty started gently rubbing her pussy against Adler's hard cock.

- Swish, swish...

"W-Wait a moment..."

In that eerie yet erotic ambience, Adler, pinned down by the professor, opened his mouth with a note of desperation in his voice.

"Thinking about it now... I like it."

"......?"

"D-Doing it with you… with the professor…”

As he spoke almost sobbingly, Professor Moriarty quietly tilted her head to the side.

"Does that mean you want to impregnate me?"

Then, the pointed question she posed made Adler stutter, his face turning pale.

"Well, that..."

"I thought so. No then."

Then, with a lopsided smirk, the professor began caressing Adler's chest where she had laid her head just moments before.

"... Then, you are indeed going to be raped by me."

"Hyuk..."

At that perfect logic, Adler involuntarily let out a frightened gasp.

- Squeeze...

"... Eh?"

Reaching down, Professor Moriarty tightened her grip ever so slightly as she held his testicles.

"P-Please, save me..."

"... Make it hard."

As she commanded with a cold smile, Adler, feeling a threat to his life, twisted his body and responded with resigned eyes.

"Yes..."

Thus, a pulsating rhythm was felt on the back of the professor’s hand, still holding onto his balls.

However, disappointingly, it wasn't the sort of vigorous movement that could satisfy the professor.

"Make it harder."

"Pro-Professor..."

"You should make it as hard as when you said you'd rape me like a horny mutt earlier. Isn't that right, Adler?"

As the professor began to caress his shivering balls with her hand, Adler's penis started to thrash wildly.

- Throb...

"... Huh?"

Just like that, his throbbing dick turned hard as a rock.

- Gulp...

"Uh..."

With her hand, she propped Adler’s hardened rod up, and then with her lower lips, Professor Moriarty tightly clamped down on his bulbous tip.

"A-Anyway, with such a shoddy pussy, only half of it enters even if you were to do it missionary style and it doesn’t allow much piston movements due to the tightness. Now if you were to insert it in that position, it would be too much, right?”

"........"

"So, just stop there. Then I'll forgive you..."

As Professor Moriarty momentarily delayed in that situation, Adler began his final desperate attempt at dissuading her.

- Splat...!

"......!!!"

However, contradicting his statement, Professor Moriarty thrust Adler's cock deep into her vagina in one go and began looking down at him with eyes filled with a sense of conquest.

"Ug-Uggghh..."

"Adler. Did you perhaps mistake my modest consideration meant to please you for my actual virility?"

Adler's face, now markedly different in demeanour, showed a confused look and a condescending sneer appeared on Moriarty's lips.

"Well, welll..."

"Just a moment, please..."

"Then, I must correct this misunderstanding."

And in the next moment,

- Splat, splat...!

"... Ugh!?"

Professor Moriarty began her merciless predation, in a femdom position where the woman rode the man wantonly.

"Pro, uhh, Profe-Professorrrrrrrr..."

Being firmly held by her two arms, Adler, unable to move, started being dominated by the professor, calling out to her in a voice mixed with moans.

"Adler, that expression..."

"Uh, ah, uhaaa..."

"You really turn me on so muchhh..."

Narrowing her eyes, she whispered into Adler's ear, continuing the violent pistoning motion.

"Ah, now that I think about it, there isn't a part of you that isn't arousing, is there?"

"Uh, ah..."

"From head to toe, you're optimised to exude sexual charm..."

"Ah..."

Already lost for words, Adler's ears were bombarded by her heated voice full of ecstasy.

"You see now, you shouldn't say anything even if you are being raped like this..."

"I-I think I'm going to cum...!"

"It's all because of your lewdness, so just quietly endure being raped...!"

The moment she finished her words,

- Buzz, brrrrrrrrrrrrrzzzz!!!

".....♡"

With her hips thrusting more vigorously than before, Adler's cock poured globs of sticky semen deep into Moriarty's womb.

"Are you... satisfied now?"

"......?"

Cradling her pelvis as if savouring his seed, Professor Moriarty finally freed his arms and silently observed Adler, who was now covering his eyes.

"You-You’ve gotten… the semen you wanted inside you…”

"Adler. What are you talking about?"

Then, with a calm expression, she caressed his cheek and whispered.

"Just one bout of insemination does not make the probability of conception one hundred percent."

"... Pardon?"

"It was written in the book. That's why I rented the entire inn for the day."

Adler, his breath rough, showed a terrified look, growing more frightened with each word the professor uttered.

"Wait, Professor... our conversation..."

"I will not compromise. Where in the world is there a rapist who negotiates with their victim?"

"Please, someone SAVE ME!"

Ignoring his plea, she clutched Adler's waist and legs tightly with her hands.

"W-What are you doing now..."

"Well, you see."

Suddenly, the professor lifted him up and moved away from the bed towards the wall.

"... I just conceived this position in my mind."

"Wait, you can't mean..."

As his back touched the cold wall, Adle’s whole body twisted and shuddered, dreading what might come next.

"It's what you might call a lifted wall press."

"........"

His ominous premonition had been revealed to be right.

"First, I plan to rape you with one of your legs on my shoulder, and later, lift you entirely to continue."

The Future Queen of Crime at the pinnacle of London displayed a genius talent even in sexual crimes.

- Swish, pop...

"Pr-Professor..."

After a considerable amount of time,

- Brrtttzzzz...

"Now, finally..."

Adler, whose legs had been forcefully wrapped around the Professor’s waist, came once more, for the umpteenth time, and buried his head in her sizeable chest.

"I can lift and pound you like this, but you're too weak to even lift me. So, just admit it now."

"Hah, haaaaah..."

"No matter what you do, you can't beat me."

Exhausted, Adler ignored Moriarty's words and breathed heavily against her chest.

"... Seeing you're silent, you must not want to admit it, huh?"

"W…. Wa… Wait… a moment."

"It's too late..."

"... Khuukgh?"¹

Watching Adler with a sinister gaze, the professor moved beside the bed, picked up Adler, and thrust him down.

- Swish...

"Pr-Professor."

The professor, grasping Adler's legs around her waist, pushed forward and mounted him; Adler, with a dazed expression, muttered.

"This is... a mating press position."

"... Mating? Press? Seems like such a position exists. I simply adopted the most advantageous posture to satisfy both rape and impregnation."

"Just, wait a moment. This is something a man does to a woman..."

"Adler, you still don't understand?"

The professor, still gazing down at him, whispered in a bone-chilling tone, filled with malice.

"You're being raped by me right now..."

"......."

"Like I was fucked like a dog by you a few hours ago, you have no right to resist now..."

Meanwhile, her buttocks slowly rose in the air.

"From your expression, you still don't understand."

"No, I do understand! I understand completely! So pleas...!!!"

"As your supervising professor, I shall guide you directly."

The next moment, her juicy butt forcefully slammed down on Adler, who was underneath her in a mating press position.

"Ugh..."

"Adler..."

As Adler, utterly exhausted, began losing his grip on reality, Moriarty leaned in close to his face.

"I love you..."

"... Ugh."

She then pushed her tongue into Adler's mouth and started violating his mouth too with a devouring kiss while mercilessly pounding away at him.

"Slurp, smack..."

"Ugh, ugh..."

Her merciless pounding, aimed at peak efficiency, continued until Adler completely blacked out.

- Brrrz, spew, splat...

"... That’s only the seventh shot.”

.

.

.

.

.

"... Uggrh."

An unknown amount of time later,

"Professor. It seems I had a terrifying nightmare..."

"........."

"It wasn't a dream."

As soon as Adler opened his eyes, the stiffness and malaise that began to pervade his whole body made him shiver and mutter, only to find himself still naked, clutched in the arms of Professor Moriarty, his cock still embedded inside her.

"So, now that I’m conscious, are you going to rape me again?"

"No, this should be enough for a demonstration."

"What?"

"And if I continue thrusting, semen will leak out, which would be a loss."

Following the professor's absurd statement, Adler quietly snickered.

"Okay. Then, I'll just go to the bathroom...?"

But soon, a bewildered look crossed Adler’s face.

"How long have you been at it?"

"Why do you ask?"

"I'm completely exhausted... My body won't move at all..."

Hearing this, Professor Moriarty smiled, not saying anything for some time.

"That's because I've cast a paralysis spell on you."

"What?"

"Well, if you pull out now, all the precious semen will spill out."

She pressed her swollen abdomen with her hands and muttered.

"So I'll keep the penis inside and sleep like this."

- Slosh...

Hearing this, Adler momentarily wore a dazed expression.

"But, Professor. I really need to use the bathroom..."

"... Ah, that's fine."

As he grimaced and muttered, Professor Moriarty stroked Adler's hair and whispered softly.

"Just do it inside me."

".... What the hell?"

Adler's eyes widened at these words.

"You might not know because you're still lacking in sexual knowledge, but that's not advisable..."

"Why not?"

"It's not hygienic..."

"Sorry, but poison has no effect on my body."

As Adler clenched his teeth and tried to pull back, the professor was having none of it.

"Anything harmful is purified as soon as it enters my body, so no worries."

"No, but still..."

"Why, do you think it's unbecoming of your respected professor?"

At that, Adler hastily shook his head.

"But I can accept anything if it’s from my beloved assistant."

"Ugh...!"

However, as the professor sneakily poked Adler's pelvis, his eyes widened and he began to convulse.

- Trickling...

Eventually, quietly blushing, Adler buried his head in the professor's chest, unable to believe what he had just done.

"Right..."

"........."

It was not until the next morning that Adler's manhood was withdrawn from the heated folds of Professor Moriarty.

- Glug... Gulp...

And behind a barrier-sealed door, an entity watched the entire scene expressionlessly.

"Haaahuuuhaaahuuuuuu..."

- Goooouuughhh... Goooooooooooo...²

"Adleerrrrrr..."

Ominous black smoke, fuelled by rage, hatred, powerlessness, a sense of loss, and an overwhelming desire for revenge, filled the skies of the rural county of Cornwall that day.

1. An onomatopoeic expression that represents a stifled or muffled sound, like a suppressed cough or a stifled sob. The latter seems to be the most likely here.2. Something like a sinister rumbling as one's magical aura rolls out or mana billows out of a character in general that illustrates the user's anger, threat, frustration, all negative emotions basically. It's often used in this novel and I thought it would be great to specify exactly what this sound entails.
