Becoming Professor Moriarty's Probability

- Swish…

Lestrade leaned forward, hands on the wall, her chest flush against its cold surface. Despite the shiver she felt running through her from the cold, she obediently pushed her butt toward Adler as he instructed.

“… Is this satisfactory?”

Lestrade asked, her tone business-like.

“……”

“… Why aren’t you replying, Mr Adler?”

However, receiving no response from Adler, Lestrade slightly turned her head back with a murmur of dissatisfaction.

- Slap…!

“Don’t look back.”

At that moment, without hesitation, Adler slapped her cheek with his palm and whispered in a low, threatening voice.

“… Ah.”

Gritting her teeth briefly, Lestrade slowly turned her head back again.

Adler observed her rear, glowing faintly in the moonlight, for some time before bending down and leaning his head forward.

“Inspector, did you get excited after swallowing my semen?”

“… Of course not. I merely followed your orders for the sake of the peace of the British Empire.”

“Is that so…?”

Then, Adler, speaking in a calm voice, slid two fingers between the legs of the inspector.

- Squish…!

“Then… could you tell me what this is?”

Gently caressing the already dripping-wet moud of the inspector, he asked her in the same low voice.

“… I’m not sure.”

“Even now?”

“……..”

As Lestrade seemed confused and denied his allegations, Adler forcefully showed her the sticky vaginal fluid stretched between his fingers, shoving it just inches away from her face.

“It’s just a physiological reaction.”

“But considering that, Inspector, you’ve only sucked on my lips and cock so far…”

“… I beg you to not pry further.”

“I’ll let it slide if you lick this.”

Lestrade glanced back, frowning at the mischievous expression he was showing her, and then sighed deeply before opening her mouth.

- Lick…

“………”

And then, she obediently began licking Adler’s sticky fingers.

“I really didn’t think you’d do it.”

“… You ordered me to do it.”

“Since I feel a bit sorry, I’ll do something for you too.”

Adler keenly observed her blushing figure, whispering as he moved behind her, lowering his stance.

- Chuu…♥︎

“Huh!?”

Moments later, Lestrade almost collapsed from the sudden, dizzying sensation she felt from her behind, her legs weakening momentarily.

“What in the… name of the lord are you doing right now!?”

“Ah, not there. Hold on…”

Adler, who had just kissed her upper labia, smirked mischievously and muttered,

“… Should have gone lower.”

“Are you insane? Please don’t…”

- Chuuu…

“… Ahhh.”

Then, lowering his stance even further, Adler now kissed her lower labia with smoldering intensity.

- Lick…

“Ah, oouh…”

Soon, as his tongue gently enveloped her wet groin, her body shivered intensely as more and more fluids leaked out of her cunt.

- Swipe…

“……..!”

Quietly savouring her fluid with his tongue, Adler then buried his head fully in Lestrade’s butt, pushing his tongue further along her folds.

“Stop, it’s dirty, please don’t…!”

- Squelch…

“… I told you not to! Ah…”

Ignoring Lestrade’s distressed cries, Adler pushed his tongue inside her with even more vigor.

“Don’t, please…”

“……..”

Both of them were lost in the pleasure, unaware of the time that had passed.

“… So this is how you taste like, Inspector. How… delectable.”

- Twitch, twitch…

Finally pulling back his head, Adler wiped his mouth with his sleeve and muttered, while Lestrade, her legs crossed, began to twitch and stagger.

“Maintain your posture. I will not let you cum if you fall down on me.”

“….. Ugh.”

However, at Adler’s words, she once again summoned her extraordinary mental strength to straighten her posture.

“Now, since I’ve cleaned up those slutty lower lips of yours…”

“Choose your words more carefully.”

“… Shall we move to the main event now?”

“……!”

Her eyes soon widened.

“That means…”

“Prepare yourself.”

Behind her, Adler quietly whispered while positioning himself against her butt.

“… It might hurt a bit at first.”

- Swish…

As Adler’s penis, straddling her taut ass, began slowly descending along the gap of her thighs, caressing her, Lestrade was forced to clench her teeth to hide her moans.

- Tszzup…

“… Kyah~”

However, that was brief, as his glans touched her vulva, her eyes lidded in pleasure and she even released a cute, unconscious moan.

- Tszyup…

“What, what are you doing…! Why don’t you put it in…”

“Mmm… Wait a bit, dear. How do I put this in?”

Despite her eyes welling up with tears as she urged Adler, he merely murmured with mischievous glee, playing with her body.

“E-E-Enough with the teasing… Now…”

“Ah, I guess.”

“….. Hm.”

Lestrade leaked out a pained gasp, as Adler, who had only been rubbing his glans against her drenched vulva, suddenly slid his throbbing manhood inside her.

“How on earth did you manage to not tear it after all this time?”

“….What?”

“I’ve heard that women who engage in rough activities almost always have their hymen torn. Considering you are always engaged in strenuous activities as an active inspector, I thought I’d be understanding if I found it torn…”

Meanwhile, as Adler pushed the tip of his glans inside her and maintained it there for a moment, feeling the tightening sensation, he could not help but question the resistance he felt at the tip.

“I’m not sure about your reasoning… but that surely sounds like an excuse.”

“……….”

“… I should know myself as I have done a lot of exercises and even constantly train hard. So, I am fairly certain that just doing a bit of rough activity should not be enough to tear it.”

Then, her face slightly reddened, she answered in a calm voice.

“So, do you mind if I tear it for you?”

“………”

“It’s a once-in-a-lifetime moment, so I’m asking one more time.”

Next to her ear, Adler began to whisper in a tiny voice.

“… Are you sure you want to give your first time to a trashy man who plans to marry you, use you as his heart’s desires, and then divorce you in a few months?”

“…….”

“We can still stop right now. I haven’t put it in all the way yet. If I pull out now, it’ll be like nothing ever happened here.”

His words elicited the inspector to silently turn her head to gaze at him,

“So…”

“… I’ve only made one request to you.”

And then she answered in a businesslike, almost mechanical voice.

“Push it in, all the way to my womb, and ejaculate inside me.”

And then, a brief silence ensued between them.

“… Did the inspector really say that?”

In that silence, Adler’s low voice quietly resonated.

- Rip…

“… Uh.”

The next moment.

“Ugh…”

The inspector, biting her lower lip, bowed her head.

“… Is it okay for the strongest inspector of the British Empire to bleed so easily at the hands of a villain?”

“Shut… up.”

That was the moment when London’s beloved idol became Isaac Adler’s woman in both body and heart.

.

.

.

.

.

“… Uh?”

Feeling Adler’s manhood filling the deepest parts of her womanhood, the inspector bit her lips hard. Soon, however, her head jerked upwards as she felt an electric current of pleasure run through her body in the next moment.

“Ah, have you not put all of it in yet?”

“I’ve only put in half so far.”

“P-P-Pardon…?”

“Shall I continue then? You’re the one who asked for it all.”

“Wa-Wait… aah…”

Soon, the inspector began gasping for breath as she felt a pleasant vibration in her lower abdomen and she almost lost conscious then and there.

- Thump, thump…

“… Ugh.”

Meanwhile, Adler, who was rhythmically thursting inside her, also secretly gasped and slightly bowed his head.

It’s too… tight.

Her moist pussy, already tight due to her robust muscles and lack of any basic masturbation experience, was squeezing Adler’s penis with even more passion than the moment he had penetrated her.

I don’t want to finish first.

As the feeling of climax began to rise prematurely along his shaft, Adler frowned slightly and stretched his hand forward.

- Swish…

“Hmm?”

He then gathered the inspector’s hands, which were pressed hard against the wall, to the middle and lifted her body.

“W-Wait… ugh.”

Then, slipping his own legs between her spread legs, Adler started to press her roughly against the wall while holding her wrists.

“Stay still.”

“But…”

Now unable to move at all in the doggy-style position, she responded with a trembling voice to Adler’s growl, her head buried in his shoulder.

“My body is shaking on its own, what am I supposed to do…”

“Is that so? Then it can’t be helped I suppose.”

Then Adler, in that position, slightly pulled back his body and pressed his cheek against hers.

- Suck…

“Ah, aah…”

As her wriggling folds, enveloping Adler’s cock, moved downwards making a squishy sound, Lestrade, held from behind in the doggy position, started trembling, not knowing what to do.

“Gia.”

“…….!”

Just then, Adler’s sweet voice whispered in her ear.

“I love you.”

“Tha-That’s not fair…!”

Adler’s unexpected love confession, starting with the use of Lestrade’s first name, threw her completely off guard. Her face flushed bright red as he fumbled for words, but…

- Squelch…!

“Haah…”

As Adler’s penis thrust back into the sticky depths of her vagina, her eyes glazed over and she moaned out loud.

“I love you, Gia.”

- Squelch, squelch, squelch…

“I love you, love you, loveyou…”

Then, gripping her wrist even tighter, Adler began to thrust vigorously inside her depths.

“Iloveyouloveyouloveyouloveyouloveyou…”

“S-S-Stop…”

As he declared his love with each thrust, the inside of Lestrade tightened around his penis further and further.

“… By the way, Gia.”

In the midst of their moaning, Adler, giving a mischievous smirk, whispered something into Lestrade’s ear that made her heart skip a beat.

“People have been watching us from behind for a while now, did you not notice?”

“…….!”

“… Ah, right. I’ve been keeping you from looking back, haven’t I?”

As soon as she heard his mischievous whisper, the inspector’s eyes widened into saucers, and she jerked her hand in an attempt to cover her mouth.

- Aaahhh…

“Ah, noo…”

But Adler, with his eyes turned red as he activated his vampiric might, used all his strength to ensure that her hands could not budge even a bit. 𝗳𝚛𝗲𝕖𝚠𝚎𝚋𝗻𝗼𝕧𝗲𝐥.𝚌𝚘𝐦

“…..♥︎”

Confused, Lestrade, in a makeshift solution, leaned her head against Adler’s cheek and began to swallow her moans.

- Mffffmf…

And the next moment, a fountain-like spray of clear fluid spilled out of her snatch in a splitting arc.

“Ah, ahhhh… ahh…”

Her face flushed crimson and her body trembled as she did her utmost to smother all of her moans.

- Vrrrr…

“Uhhhhh…”

Soon, as Adler’s cum filled the deepest depths of her pussy and womb, she could not hold back her moans any longer.

- Brrttt…

Just like that, they were lost in the throes of pleasure, unable to compare the passage of time.

- Thud…

Overwhelmed by the odd yet arousing sensation enveloping her whole body, the inspector trembled and eventually collapsed on the spot.

“”……….””

Then, silence descended between them.

“… It was actually a joke.”

Amid the silence, Adler, still pressing her against the wall while holding her wrist, whispered in a mischievous voice.

“Haah…”

With her face still flushed, Lestrade glanced at him and quietly sighed.

“Animal.”

Hearing that, Adler smirked and stood up.

“It seems I have lived to see the day when it is not me who calls someone that, but the other way around.”

“… What?”

“Forget it. Now, get my penis hard again, inspector.”

Saying so, he, barely diminished in arousal despite the intercourse, thrust his penis towards her face, commanding her once more.

“How do I… what?”

“Inspector, why don’t you show me the most lewd act you can think of?”

“…… Understood.”

She glared at him for a moment, then sighed, knelt down, and sat modestly in front of Adler.

“Is this… how it should be done…?”

As she crawled forward, she took Adler’s balls into her mouth and, nibbling cautiously, posed the question.

“Not bad, but it’s lacking a bit.”

“………”

“… Ouch, ouch, ouch.”

However, as Adler looked down and responded, Lestrade quietly furrowed her brows and gritted her teeth.

- Swish, swoosh…

Finally resigning herself, she wrapped her hair around Adler’s dick and began rubbing it back and forth while swallowing his balls again.

- Wiggle…!

Abruptly, his dick stiffened and returned to its impressive form.

- Slap…!

“Shall we start from the beginning then?”

Adler, bringing his dick to slap the inspector’s cheek, gently stroked her head as he asked.

“… Until when?”

Lestrade, looking up at him, felt her bloated belly vibrate again and asked back.

“How about until the fog that covers us lifts?”

“… If that is what you command.”

And shortly after, their raunchy moans began echoing once more inside the deserted alley.

.

.

.

.

.

As more and more time elapsed, the dense darkness and fog that had enveloped the surroundings began to clear, and morning sunlight beamed down amidst the clouds of London.

“Now… I think we should put a stop to this act, don’t you think?”

“… My thoughts exactly. If we continue like this, we might both be arrested for public indecency.”

In the still-dark alley, Lestrade and Adler, utterly exhausted, miraculously agreed for once and took a step back from each other.

“…”

Soon after, the two began to look at each other with slightly awkward expressions.

“Well, then… I… I should get dressed.”

“… Y-Yes, me too.”

Though they had spent the night in animalistic intercourse with a sober mind, they now acted as if it were a drunken blunder, quickly turning away and getting dressed.

- Swish, swish…

- Rustle…

Once they were properly clothed, they finally looked like proper humans instead of animals in heat.

“Well, um…”

“… Yes?”

Just then Lestrade’s somewhat naive voice reached Adler’s ears.

“… With this, I should definitely get pregnant, right?”

Adler, quietly turning his head, began to swallow dryly.

“The semen, uh… keeps leaking out… Is this normal?”

Lestrade, still in her police uniform, was pulling down her trousers and peering into her underwear as she muttered in an absentminded voice.

“Just wait.”

“… Ye-Yes?”

Due to her remarks, Adler lost himself to his animalistic instincts then and there.

“If you’re that worried, I can give you some more.”

“Wha?”

He grabbed the undergarments Lestrade was peering into and, thrusted his cock forward and pistoned inside.

“I-It’s… daytime now!”

“… So it’s not okay during the day but it is at night?”

“No, that’s not what I—“

Before she could push Adler away in an effort to maintain her sanity,

- Buzz, bzzzz…

His throbbing cock began to ejaculate his genes into her panties.

“… This isn’t right.”

As her underwear became completely soaked with Adler’s semen, she began to mutter with a gloomy expression.

“If I don’t want to be late… I need to go to work right away.”

At those words, a shadow of depravity slowly crept into Adler’s eyes.

“Don’t change, just go to work like that. Getting pregnant isn’t guaranteed in one go, we need to maximize the chances.”

“… What?”

“And from now on, before you go to work, always insert my semen into your panties and your vagina. Keep it that way until you finish your shift.”

Lestrade frowned at this, prompting Adler to add in a low voice,

“… It’s an order.”

Quietly bowing her head and blushing, Lestrade replied,

“I really don’t like this…”

She quietly pulled up her damp underwear and muttered,

“If it’s an order, I have no choice.”

- Thump, thump, thump…

Her heart still throbbed as if it would burst.

“I have no choice but to comply.”

- Kyu…♥︎

Her lower abdomen intermittently trembled, hinting at her slight regret, as she kept her feelings hidden to the end.
