Becoming Professor Moriarty’s Probability

"... Hiihk."

As Adler's stiff rod penetrated the professor's tight folds, a heated moan escaped her quivering lips.

"Uh, ughhk..."

"Haah..."

Adler, taken aback by the unexpected tightness, abruptly paused his thrusting and collapsed onto her back.

"... Professor, your vagina is so tight, yet so supple at the same time."

His eyes narrowed as he whispered into her ear, causing Professor Moriarty's gaze to wave violently.

- Slap...!

".......!"

"Are you... crazy...?"

"Stay quiet. You talk too much for someone being fucked like a dog."

His insolent behaviour made Professor Moriarty murmur in her usual cold voice, though Adler was not the least bit shaken.

"Even though you’re looking at me with those scary eyes of yours, you're still getting rammed from behind by my penis, aren't you?"

"... Eek."

"I'm not scared at all."

He thrust the entirety of his hefty length roughly into her, effectively silencing her words midway.

- Squelch...

"Uh, ugh..."

As the tip of his bulbous glans touched her sensitive spot, Professor Moriarty momentarily lost strength in her legs, letting out a dazed moan and collapsing on the bed.

"Oh, how adorable..."

"Stop... teasing me..."

"But how can I, when the foolish professor is acting so cute?"

He gently stroked her smooth and supple butt with his hand, then slapped it again, taking care to be gentle.

- Slap...!

"........"

This time, the professor clenched her teeth and held back her moans, but she couldn't prevent Adler's red handprint from appearing on her smooth behind.

"... You beast, uh?"

- Swish...

Consequently, as she shivered and was about to speak, she quietly shut her mouth due to the ticklish sensation that started coursing through her abdomen.

"Professor's belly, it's so soft..."

Adler resumed his thrusting, grabbing and pressing her belly with his hand.

"Eek, hihk... eek..."

"Didn't know the professor could make such noises..."

"... Stop, enough already!"

As Adler persistently pressed her heated pelvis, Professor Moriarty's mind started going blank, and she even started murmuring urgently.

"Let's... take a little... break..."

"Break? What break?"

"... Heuk?"

Silently leaning his bare body against her waist, Adler pushed his shaft deep into her depths while whispering to her in a cold voice.

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

".........!"

"If this continues, you'll be getting yourself a creampie."

The cold voice of the male dominating her sent a chilling sensation throughout her body.

"And eventually, you'll become pregnant with my child."

At that moment, Adler whispered teasingly and slowly pulled back before thrusting in forcefully again.

- Psshhh... Drip...

Suddenly, the sound of leaking water echoed from below.

"... Ah."

Right after that, Adler looked momentarily puzzled at the professor, who had buried her face in the bed sheets with both hands covering her face, then lowered his gaze and smirked at the scene.

"Did you cum before me, Professor?"

- Bzzztt...

"A student ten years your junior says something lewd, and that's all it takes for you to come?"

Even at that moment, Professor Moriarty, instead of responding, merely trembled all over, albeit nigh-imperceptibly.

"Truly hopeless."

"......"

"Did the thought of carrying my child please you that much?"

As Adler asked with a sly smile, she quietly turned her head back and replied in a low voice,

"... Yes."

With that, a heavy silence enveloped the duo.

"It really turns me on..."

"Oh."

Normally, Adler would have snapped back to caution at her suddenly sincere tone.

However, his body, heated up by the pink fog, clouded his reason and judgment.

"Adler..."

"If you desire it so much, why don't you take a seat?"

At his command, Moriarty, with trembling legs, moved to sit on the bed.

"No, I meant sit on my legs."

"Oh..."

With a puzzled expression, she moved her body and soft butt onto Adler's legs and sat down as he instructed.

"Good. Now, embrace me in that position."

"Is this how it's supposed to be...?"

"Are you only going to use your arms? Wrap your legs around my waist as well."

Thus, under Adler's lead, they naturally assumed a face-to-face position.

"T-This..."

"What?"

"... It's too embarrassing."

As Moriarty, face flushed and her body touching Adler muttered in a shy tone, a sneer formed on his face.

"Didn’t you find it embarrassing to be pounded like a dog just earlier?"

"W-Well, th-that was different... we weren't making eye contact..."

"Enough, stick out your tongue."

At his words, Moriarty, looking down, sheepishly stuck out her tongue.

"... Mmmph."

"......!"

Adler, lightly nibbling on her tongue, then slightly lowered his posture and nipped at Moriarty's neck.

"Ow, that hurts..."

"... I intended for it to hurt."

Then, satisfied with the mark of his teeth on her neck, Adler began to kiss her lower and lower.

"Chup..."

"... Haaah."

As his tongue touched the tip of Moriarty's breast, her pelvis, pressed against Adler's, began to tremble.

"S-Stop sucking me already..."

".........."

"... Why are you so skilled at this."

In that state, Moriarty buried her head into Adler's neck with a shy expression. Yet, a slightly cold voice leaked out of her as she witnessed how skilled Adler’s sexual expertise was.

"Professor, your nipples have become so hard. They should be really sensitive right now.”

"Ah..."

At that voice, Isaac Adler briefly looked up, caressing her hard nipples with his hands, and whispered in a low voice.

"S-Stop...!"

Then, Adler bit down on the tips of her breasts again, gnawing them gently.

"... I told you to stop."

Initially, the Professor twisted her body in discomfort at the tingling unpleasantness that ran along her body with his teasings. Gradually, however, a strange emotion and sensation began bubbling inside her.

".....!?"

Eventually, she unconsciously patted Adler's back and started wearing a genuinely perplexed expression.

… That can't be.

Regardless of age or gender, if it were for her amusement, she had mercilessly killed without a second thought. However, the emotion she was feeling now was completely alien to her, triumphing any emotion she had ever felt.

I shouldn't be feeling such lowly emotions...

Because such were the prerogatives of inferior beings and species. A superior race like herself had no need for love or maternal instincts.

But this is...

Then what was this trembling emotion filling her body now?

"........."

Now, even breaking into a cold sweat, Professor Moriarty quietly sunk into deep thoughts.

What if she, according to plan, carried Adler’s child in her womb?

And what if she were to breastfeed the child who comes into the world?

"Ah...?"

Just imagining that, her chest throbbed violently, and the emotion enveloping her body intensified several times over.

… This can't be.

Surely the child she would conceive today was supposed to be nothing more than a tool to neutralize her curse by keeping Isaac Adler close.

Why then did she have such a ridiculously splendid thought that it wouldn’t be a waste at all to devote her everything to such a child?

"Phew..."

"........."

And why did she feel a similar yet subtly different feeling for Adler, who had just detached his mouth from her chest?

"... Ah?"

The genius, who knew everything since birth, began wearing a vacant expression as she stepped into the realm of the unknown for the first time in her life.

"What are you doing, Professor?"

"... A-Adler."

"Why aren’t you focusing."

Narrowing his eyes to look at her, Adler whispered in her ears in a cold, detached voice.

"Why aren’t you putting it inside?"

Feeling his rock-hard cock, which had been rubbing against her pussy, throbbing erratically, the Professor, embarrassed, buried her face into Adler's shoulder.

- Squelch...

"... Heugh."

Then, lifting her buttocks slightly, she pushed his rod, which still felt imposing despite the earlier sessions, into her vagina.

"Wiggle your hips. This time, the professor will do it by herself.”

"Yes..."

With that, she impaled his elongated cock inside her depths and started undulating her hips, tightly embracing Adler.

- Clench, tighten...

In the next moment, her vagina started gripping his pulsating cock even tighter than before for some reason.

"Ah~... Adler..."

"... Huh?"

Feeling each of her wriggling folds clinging to his prick, Adler's previously relaxed expression began to contort.

"I love you..."

- Squelch, squelch...♡

At that moment, Moriarty's whispered confession reached his ear.

- Squeak, squeak...

- Brrr, brrrt...

Because they were in the face-to-face position, their bodies touching each other, they began sharing the quivering their bodies made.

"Why... are you suddenly so good at this..."

"Because I love you… Adler..."

"... I think I'm going to cum soon."

The professor, who had been shaking her hips with eyes unfocused and drooling, suddenly widened her eyes at Adler's trembling voice.

"R-Right now...?"

"Yes, Professor. I'm going to cum inside you."

"Ah..."

"Are you ready to take it all...?"

Soon, Adler's reply returned, and the professor, unable to say anything, just quietly nodded.

"Mmph?"

"Professor..."

Adler, holding her cheeks and aligning them to his eye level, whispered as he felt her searing warmth.

"I want to kiss you while I fill your insides..."

"......"

“It’s okay, right?”

Once again, the professor, unable to utter a word, thrust her tongue into his mouth instead.

- Gush, gurgle...!

And at that moment, Adler's penis, trembling violently inside her pussy, started to forcefully spurt out thick ropes of white semen.

"....! .....!!"

Feeling the semen flood her cervix, Professor Moriarty, intertwining tongues with Adler, tightly closed her eyes.

- Gurgle, grr...

Thus, simultaneously, they shuddered and reached that sweet release.

"How long... are you going to keep coming…!?"

"... I don't know either."

Was it because of the pink smoke still filling the room? The afterglow of their climax didn't completely fade until several more minutes had passed.

"Ah... Haaah..."

An unknown time later,

"......."

Jane Moriarty, barely releasing the embrace, fell backwards and silently began stroking her noticeably swollen belly.

"So, inside here now..."

- Rumble...

"Is my child going to grow..."

Then, murmuring to herself, she wore a strange expression.

"... No."

"........?"

"I did cum inside you, but there will be no conception."

However, her barely discernible emotion shattered at the bombshell Adler threw at her with a smug smirk.

"Why…?"

"Because I've placed a contraceptive spell on myself."

"........."

"Did you really think I was going to impregnate you?"

Due to this, Professor Moriarty, who had been staring blankly at Adler, started throwing a malicious scowl toward him.

"Fool. Idiot. Worthless whore."

"......."

"Did you think I would simply pass on my genes?"

But Adler, already too far gone in the realm of delusion, was oblivious to the reality.

"I'll release the contraception at the very last moment."

"... Ah."

"That way, Professor, you'll follow my words..."

Muttering in frustration in front of the professor, Adler then bowed his head and muttered to himself.

... Of course, I will be returning to the real world, so there will be no need to undo the contraception.

At that very moment, he made a rather rational decision with the little sanity he had left.

"Who decided that?"

"... What?"

Coincidentally, it was then that Moriarty's sanity had finally snapped.

"A contraceptive spell, you say?"

"That's right..."

"That sort of thing can be undone with a flick of my finger."

As the professor suddenly leaned in with a menacing look, Adler, still not fully grasping the situation, started scratching his head and muttering.

"I'm sorry, but even if you undo the contraceptive spell now, it won't implant seeds in the already discharged semen."

"......."

"And from now on, I won't be doing anything with you, Professor?"

Then, Moriarty, wearing a cold smile, leaned in even closer to Adler.

"I was going to go about this nicely, but it seems you are really beyond saving."

"... That, is a bit presumptuous of you, don’t you think?"

"I have no choice then."

She whispered chillingly close to Adler's ear.

"Guess, I will just have to rape you.”

At that moment, Adler, staring dumbly at the professor, opened his mouth with a slightly trembling voice.

"I-I don't want that."

Hearing this, she quietly stood up, her smile smeared with immorality.

"Good, that will only make it more exciting for me."

"... Ah."

Meanwhile, at that time, a corridor had been completely turned into ruins due to the aftermath of someone's reckless usage of unrestrained mana,

- Creak, creak...

At the end of it, a figure, who was unable to open the door despite her efforts, was injecting her mana into the gap of the unyielding door, her eyes void of light as she captured the scenes inside.

- Creakkkk...

Regrettably, that figure was none other than Charlotte Holmes, who had just arrived at the scene seconds ago, all according to the professor’s plans.
