Becoming Professor Moriarty's Probability

0% - Slurp... Squelch...

A peculiar sound, as if something was being sucked, echoed through the hotel room.

“Is it delicious, Adler dear?”

“.......”

The reason was none other than Isaac Adler, his face flushed a deep crimson, suckling on the professor’s breast.

“If it’s delicious, just give me a nod.”

“........”

“See, I knew you’d enjoy it.”

As Adler shyly nodded while glancing at Moriarty, she let out a small chuckle, gently stroking his head.

“Wouldn’t you agree that this is better than some flat, unimpressive chest?”

“What...?”

“I’m genuinely curious about what that brat plans to do if she ever has a child. Will the poor baby starve because she can’t even feed the youngling?”

“.......”

She then casually tossed a provocation toward Charlotte, who sat at the edge of the bed, grinding her teeth and glaring daggers at her.

“Oh, if a wet nurse is ever needed, do let me know. I’d gladly lend one of my ample breasts to substitute for your pitifully inadequate...”

- Bang...!

“... Oh dear, what’s all this now?”

Before Moriarty could finish, Charlotte, eyes blazing with fury, lunged toward her. But the professor, lowering her voice, gestured at Adler, who was still utterly entranced, suckling at her breast.

“Do you want Adler to get hurt again?”

“Ugh...”

“Or, do you want Adler to pounce on you again?”

That silenced Charlotte, her mouth snapping shut as she had no retort.

Was it Adler’s imagination, or did he momentarily see the look of crushed self-esteem that had lingered on Charlotte’s face just days ago?

“... Phew.”

Noticing this, Adler hesitantly pulled away from Moriarty’s breast, glancing at Charlotte with a mixture of guilt and unease.

“No, no, Adler.”

“Ah.”

“Come here, just lie down on my lap for a moment.”

Before Adler could even react, Moriarty gently pushed him down onto her lap, a languid smile spreading across her face as she began stroking his hair once more.

“Now, isn’t this every man’s dream?”

“.......!”

Before he could respond, Moriarty pressed her breast back into his mouth, her hand wrapping firmly around his cock.

- Tap, tap, tap...

“Go on, indulge yourself as much as you like.”

As the sweet liquid began to seep into his mouth and the rhythmic motion of her hand started, Adler’s mind began to drift hopelessly into a haze.

“Good boy, that’s it...”

Of course, Moriarty herself was deeply aroused by this twisted situation.

“You’re like a baby...”

For a woman who had only just begun to grasp the concept of love by equating it to “maternal affection,” this obscene act, which played on and perverted that very maternal instinct, could only evoke an overwhelming sense of forbidden pleasure.

- Drip...

Transparent liquid began to trickle down from the professor’s damp slit, and Adler’s cock twitched intermittently, betraying his struggle for control.

“Finding it hard to hold back?”

“........”

“Then, just let it all out.”

At that precise moment, a soft, coaxing voice whispered into Adler’s ear.

“Hngh...!”

The fact that the voice belonged to none other than Professor Moriarty, a woman capable of killing without batting an eye, only served to heighten Adler’s overwhelming sense of forbidden ecstasy.

- Splurt, nibble...!

“Ahh... biting’s against the rules, you know.”

As she spoke, Adler, unable to contain himself, bit down lightly on the professor’s breast, his hips lifting as he released thick, white streams of his seed.

“Still, you’ve done well...”

Moriarty turned her head, intending to witness the sight of his cock pulsing, releasing his potent essence and staining her hand. Yet, mid-sentence, her words faltered.

- Slurp... ♥︎

“........”

Charlotte, who had somehow managed to wrap her soft lips around the tip of Adler’s cock, was now carefully collecting his semen into her mouth.

“You dare...!”

- Gulp...

The professor, momentarily frozen as she watched, extended her hand in haste. But it was already too late— Adler’s sticky, viscous semen had already slid down Charlotte’s throat, settling in her stomach to be digested.

“Tastes just like milk.”

“.......”

Charlotte’s casual remark was accompanied by a sly grin, her expression only serving to deepen the scowl on Moriarty’s face.

“Urk...!”

“Professor!”

The tension reached a boiling point when Moriarty suddenly lunged forward, her hand wrapping tightly around Charlotte’s neck. Adler, who had been lying dazed on the bed, quickly sat up, alarmed.

“You promised!”

“.......”

“You don’t want to repeat that day, do you? Right?”

His words instantly struck a chord. Moriarty’s hand trembled before she finally, reluctantly, let go of Charlotte’s throat.

“Haa...”

The professor sighed deeply, her expression betraying her frustration at not being able to snap Charlotte’s neck. She then turned away, calmly kneeling on the floor.

- Shuffle...

Lowering herself further, she leaned into a prone position, pressing her body submissively against the ground.

“Ah...”

The sight triggered a flashback in Adler’s mind— his first encounter with her. He stared blankly, mesmerised by the familiar scene.

“What are you waiting for?”

She pressed her hips back slightly against him, her whisper barely audible, yet full of invitation.

“... Hurry and put it in.”

As if bewitched by her words, Adler found his body tilting forward involuntarily.

- Slide...

“........?”

Yet, just as Adler shifted closer, a victorious smirk appeared on Moriarty’s lips— hidden from his view. In the small space beneath her poised figure, Charlotte suddenly slipped in, her unexpected move catching everyone off guard.

“What the...”

“Ah, ahh... it’s not over yet, is it?”

The professor, now unintentionally pinning Charlotte beneath her, grimaced at the sensation of their chests and stomachs pressed together, opening her mouth to protest. However, Charlotte spoke first.

“Ad-Adler hasn’t completely decided to go with you yet...”

“Hah?”

“S-So... he could still choose me...”

And then, there was silence.

“... Pfft.”

In the stillness, the professor let out a small scoff, looking down at the teary-eyed Charlotte as she whispered in a venomous tone.

“No male would feel lust for such a pitiful, underdeveloped body.”

“.........”

“Compared to this childish figure, it’s natural that he’d prefer my mature body, isn’t it?”

But just as Charlotte’s expression grew darker with each passing second...

- Squish...!

“”.........!””

Adler’s cock, without warning, slipped between their overlapping slits.

“... Ah, sorry.”

“”..........””

“You were... stacked so closely together.”

The strange sensation caused both women to instantly clam up, their eyes wide in shock. Adler’s voice, tinged with embarrassment, echoed moments later.

- Grind...

“Uh, um... but...”

His voice suddenly began to tremble slightly.

- Grind...

“... This actually feels quite nice.”

The next moment, Adler’s cock, which had withdrawn, slid once again between their tightly pressed folds.

“W-What...”

“G-Get away from me...”

The peculiar yet undeniably sensual sensation made both women flinch. As their eyes met, they exchanged disgusted glances, attempting to push each other away.

- Grab...!

“Hngh?”

But Adler suddenly grabbed the back of the professor’s neck, pressing her firmly against Charlotte’s body with all his strength.

“Stay still, you fucking bitches in heat.”

“... Adler?”

“Stop your damn whining and squirming...”

The professor, startled by his unexpected force, managed to stammer out a confused response, but Adler’s cold voice immediately cut into her ear.

“Just shut up and keep your cunts ready...”

“Uuhh?”

“Ah?!”

As Adler’s cock began to heat up and throb intensely between their pressed lower abdomens, both women involuntarily let out soft moans.

“Listen up. I’m giving you five seconds. If you don’t want to pass out from hyperventilation, start breathing now.”

“”.........?””

Adler’s icy words sent a shiver down their spines. Caught off guard, the two women instinctively clasped each other’s hands in panic.

“... I warned you, didn’t I?”

Watching them closely, Adler let a sly smirk curl at the corners of his lips before burying his face into the professor’s shoulder.

“Y-You... Just what in hell did you do to Adler?”

“I-I didn’t do anything...”

“Don’t lie to me! Speak up properly!”

In the short silence that followed, Charlotte, sensing that something was terribly wrong, whispered her urgent question to the professor.

“I-I... just...”

The professor, sweating profusely from a chill she had rarely felt in her life, finally avoided Charlotte’s gaze and quietly confessed.

“... I only played a tiny little trick with the breast milk.”

And then, silence descended on the scene.

“You... you...”

Charlotte was the first to break the silence, fully aware of what happened when Adler consumed alcohol or drugs. But before she could finish,

- Squelch...!

“You absolute idiottttttttt!”

Charlotte’s sharp, delicate scream echoed as Adler’s cock suddenly, and without warning, plunged deep inside her unprepared pussy. Her body twisted helplessly, caught completely off guard by the abrupt penetration of his thick meat stick.

“Ah...?”

Meanwhile, the professor, who had been watching Charlotte’s reaction with a slightly dazed expression, slowly turned her head with a subtle glare.

“... Adler, why...?”

“Why, you ask?”

Adler, fixing her with a cold stare, furrowed his brows as he answered.

“I made it very clear, didn’t I?”

“W-What exactly...?”

“That you had to convince me logically why I should choose you first.”

At those words, the professor flinched visibly.

“... Not by spiking your breast milk, Professor.”

Adler’s sharp remark drove the point home, leaving the professor momentarily breathless.

“Professor, I’m disappointed in you.”

“Ad-Adler...”

“Why don’t you just masturbate while watching Charlotte’s face for some time, huh?”

Still frowning, Adler grabbed the professor by the scruff of her neck, pulling her forward to force her to look directly at Charlotte’s flushed, contorted expression.

“B-But...!”

- Smack...!

“... Ahh!?”

Before she could even attempt an excuse, Adler’s hand came down on her ass hard enough to leave a bright red handprint.

“Shut up and masturbate already.”

“.......”

The professor, who had likely never been struck by anyone in her life, stood frozen, her head bowed in silent submission as her trembling buttocks betrayed her humiliation. Adler leaned closer, his voice a low, menacing whisper.

“Who knows? If you try hard enough, I just might fuck you too.”

The professor blinked at him for a moment before, with a defeated expression, she lowered her hand to her slick, dripping slit.

“...... Yes.”

It was at that moment that the bedroom tyrant was born.

An unknown passage of time later,

“Hello, everyone!”

Mycrony cheerfully announced her arrival, having finished her leisurely bath downstairs and fully prepared for the night. Swinging open the door to the VIP room with confidence, she stepped inside.

“What on earth are you all doing in here, setting up such top-tier barriers and... huh?”

However, as her eyes took in the scene before her, she froze, her expression blank and her mind unable to process what she was seeing. For the first time in her life, she was speechless by a scene that she could have never imagined.

“Hngh, ahh... uhh...”

“Haahh... ahhh...”

Charlotte and the professor were both sprawled face down on the bed, trembling as their hips were raised high, their thighs dripping with a mixture of thick, white cum and their own sticky juices.

- Slick, squelch...

“Hmm?”

Adler, casually plunging his fingers between their soaked, twitching slits, turned his head when he noticed Mycrony standing in the doorway.

“Miss Mycrony.”

- Splurt...!

- Drip, squirt...

At that very moment, yet another spurt of sticky liquid gushed out from the two women’s abused entrances, as if on cue, causing their bodies to violently spasm from the sensation.

“... Care to join us?”

Mycrony, who had been staring at the scene in a daze, felt a cold bead of sweat slide down her temple as she processed Adler’s invitation.

“... Once my little sister gets a grip on herself, sure.”

A smile brimming with deliciously sinful intent crept across her lips, betraying her growing intrigue at the debauched spectacle she had just walked into.
