Becoming Professor Moriarty's Probability

“… Ugh.”

As Isaac Adler opened his eyes and became aware of the scene unfolding before him, Charlotte Holmes’ inner folds clung tightly along his member.

“Is it growing even bigger inside?”

- Squirm, squirm…

“Honestly, my vagina is starting to ache.”

Realising that his dick was poking deeply inside her, Charlotte murmured with a smirk.

“Miss Holmes…”

“…..?”

“Just, just a little… slowly…”

Hearing almost a whimpering voice coming from below, she tilted her head curiously and looked down.

“I, I feel like I’m about to reach my limit…”

“Even if you can’t be gentle… could you at least coordinate with me…?”

Isaac Adler, shielding his eyes with his arm, blushed and muttered.

“Why are you suddenly acting as if it’s unfamiliar?”

“… What?”

“You must have done this a lot, right?”

After looking down at him with a wavering gaze for a moment, Charlotte coldly replied and began grinding her hips on his thighs.

“Uh, ah… Bu-But… Eep…”

“Speak clearly.”

Feeling his mind go blank as her tight walls clenched unlike anything he had experienced before, Adler jerked his waist and stammered out.

“Being with someone I genuinely like is a first for me…..”

Of course, it was a cunning statement that intentionally omitted a certain professor whom Adler liked just as much as Charlotte.

“That’s why… I wanted to enjoy it gently, kissing and embracing each other lovingly as we rejoice in our union…”

- Thud, thud…

That was enough to send Charlotte, who was already close to losing her sanity, over the edge.

I want to get pregnant, I want to get pregnant, Iwanttogetpregnant…

“Ah, ah? Ahhh…”

As soon as he finished speaking, her walls tightened even more, causing Adler’s whole body to tremble.

Charlotte’s face flushed a deep crimson as she looked down at him.

- Brrr…

Her tight pussy heated and convulsed violently at the thought of receiving the fresh genes of the boy beneath her.

“Miss Holmes! I, I… I’m at my limit?”

“… I know.”

After some time had passed, as Adler’s panting voice was heard, Charlotte responded with a hoarse voice, still grinding her hips against him.

“Come inside me and get me pregnant.”

“Wait, just…! Ah…!?”

“It’s an order.”

Adler tried to twist his body to avoid unloading inside her, but Charlotte, using her legs to completely wrap around his waist, exerted her dominance over him with a gleaming look in her eyes.

- Brrrrrut!! Brrut…!!

“… Ah.”

The next moment, Adler’s thick rod released a torrent of cloudy semen and began filling Charlotte’s pussy to the brim.

“Harder. More, just a bit more…”

“Ah, ahh…”

Charlotte, feeling the intense pounding deep inside her, collapsed onto his body with a dizzying look in her eyes.

“Fill my womb completely…”

She whispered into Adler’s ear, asserting her control over him once again.

“… Are you just going to knock at the cervix? My womb is still pretty much empty.”

“No, where on earth did you learn about sex…”

“From the forbidden books in the library.”

“…. Ah.”

Realising the source of her obscene knowledge, Adler started muttering resignedly while turning his gaze away.

“So the girl detective I idolized has turned into a lustful beast…”

“Miss Holmes, I’m disappointed.”

Charlotte paused slightly at the coldness in his voice.

“I think I might have gone a bit too far…”

“… Still, I love you.”

However, Adler’s flushed muttering stopped her excuses, and her breathing quickened again.

“So, shall we rest a bit?”

“If we continue like this… I feel like my mind will go blank and collapse…”

- Squelch, squelch…

“… Huh? Hey!?”

Noticing her hesitation Adler suggested a break to recuperate. However, his expression turned to panic as he felt Charlotte’s hips begin moving back and forth again.

“Adler… AdlerAdlerAdler…!”

“Ca-Calm down! I just came…! I just caaaame!!”

“Adlererrrrr…”

“Ughh… Ugh.”

As Charlotte’s eyes rolled back into her head in pleasure, she desperately cried out Adler’s name and shoved her tongue into his mouth, wildly shaking her hips like a dog in heat.

- Plap, plap, plap…

“… Ugh, ugh.”

For a while, only the sounds of tongues entwining and flesh slapping against flesh echoed through the hotel room.

.

.

- Vrut, Vrrrrut…!!

How much time had passed?

“Uh, ugggh…”

“Phew…”

Charlotte and Adler, covered in each other’s fluids and sweat, finally collapsed simultaneously after cumming for the umpteenth time.

And then, there was silence.

“You’re not asleep, are you?”

“Hikk.”

As Charlotte, who had been lying on Adler’s body, whispered in a low voice, Adler, his eyes closed and legs trembling non-stop, suddenly opened his eyes in surprise.

“Ah, are you going to… rape me more?”

“Then really, let’s just rest a bit… Think about the person being raped, no… put yourself in the devil’s shoes…”

Adler murmured to Charlotte, shrinking back,

“… Shall I be gentle?”

“Yes?”

He, upon hearing Charlotte’s soft voice, opened his eyes wide.

“You told me, right…? That you wanted to be gentle with me and embrace me.”

“… I did.”

“Now, my mind has cooled down a bit, so I think I can do it.”

“Ah, um…”

However, Adler’s reaction was lukewarm, considering it was the girl who had just fucked him like a dog.

“If you don’t like it, I can’t help it. Just lie down and rest.”

“Haaah, let’s have gentle sex, shall we…?”

As Adler showed sudden interest in Charlotte’s remark, she, now with a satisfied expression, whispered in a low voice.

“Then I need to get you hard again, so I’ll start by licking your balls?”

“… Yes?”

And then, she quietly moved downwards and burrowed between Adler’s legs.

- Lick, lick…

As Charlotte earnestly started licking Adler’s balls with her tongue, his limp dick began twitching again, showing a sudden surge of liveliness.

- Chu, nibble…

“Uh…!”

“… Oh my.”

After a long period of ministering his balls with her mouth, Charlotte looked up shyly when Adler’s dick sprang back into action.

“See? It’s not rape, it’s pure love, right?”

- Swish, swish…

“Your penis is also earnestly agreeing, see?”

She whispered as she gently rubbed the tip of Adler’s penis with her palm, causing Adler, his cheeks red to the ears, to open his mouth.

“So, how do you plan to rape me gently?”

“Hmm…”

Charlotte then seemed to ponder for a moment.

“Aha.”

Suddenly, she gracefully lay on the bed and spread her arms, causing Adler to tilt his head in confusion.

“Maybe it’s because I learned about sex through erotic stories… I don’t know anything about gentle sex.”

“So, I’ll just stay still. Mr Adler, I’ll leave it up to you.”

To him, Charlotte whispered in a low voice.

“Try to eat me up gently.”

- Thump, thump…

As she finished speaking with a blushing face and shyly averted her gaze, Adler’s heartbeat began to accelerate.

“… Can I be a bit rough?”

Then, a slightly absurd question leaked from his mouth.

“You can even rape me.”

And Charlotte responded with a ridiculous answer of her own. Silence soon permeated the room for a moment.

“… What are you waiting for?”

Charlotte’s heated voice echoed in the room amid the silence, and Adler’s eyes started growing dizzy with lust.

.

.

.

.

.

- Plap, plap, plap…!

“Ah, ah, uh…”

The sound of flesh fiercely clashing and subdued moans, now several times shyer than before, began to echo in the hotel room.

“U

Charlotte, who was on all fours on the bed receiving Adler’s cock, now closed her eyes tightly and bit into a pillow, perhaps embarrassed or trying to suppress her sweet cries.

- Smack…!

“… Aaah!?”

Just like Charlotte had been earlier, Adler, swaying his hips like a beast, continued thrusting into her non-stop. When he smacked her buttocks with his palm, Charlotte, her eyes wide open, eventually let out a provocative moan.

- Smack, smack…

“Ah, it hurts…”

- Smack…!

Adler continued smacking her buttocks with his palm, increasing his thrusting speed, not paying heed to her words.

- Swish…

“Uh!?”

He soon reached forward and grabbed Charlotte’s breasts, causing her body to jerk up and shiver, a shocked look on her face.

“Uhh…”

Adler, while gently circling her nipples with his fingers and softly nibbling on her nape, started licking her skin passionately.

“… So skilled.”

Charlotte, forcefully suppressing her moans, pouted and shot back at him.

“It feels like… your breasts have gotten a bit bigger.”

“Is it just my imagination?”

Curious, Adler asked her a sudden question.

“M-Maybe because I touch them every day.”

“What?”

Charlotte, her cheeks flushing, murmured looking downwards.

“… Because I always think of you when I masturbate and grope them, they might have grown a bit.”

A vacant look settled on Adler’s eyes at her remark.

“Ah, if you like them small… I won’t touch them anymore when I masturbate.”

“… No, they’re perfect.”

“Ah!?”

As he watched her reaction, Adler caressed her breasts and whispered into her cheek.

“I love you, Miss Holmes.”

“… Talk to me informally.”

“I love you, Holmes.”

“Uh, call me by my first name…”

Still looking down, Charlotte moaned as she made her request.

“And, can you talk to me face-to-face…?”

“It’s weird to say this now… but, be a bit more gentle.”

- Swish…

“… Eeek.”

Adler, gazing intently at her, grabbed her arms and swiftly flipped her body over.

“I love you, Charlotte.”

And then, he thrust his cock deeper into her than ever before, looking into her eyes that were now dyed in his colours as he whispered.

“… Me too, Isaac.”

At that moment, Charlotte, wearing a shy, almost girlish expression she’d never shown before, quietly wrapped her legs around Adler’s waist.

- Whirr, vrrrrrrt…

Adler then plunged his tongue into her mouth as he came inside her, far longer than at any other time today.

- Vrrrt, vrrt, vrrrr…

And after more than a minute of cumming continuously, neither Adler nor Charlotte had any rational thought left in them.

“… Shall we go again?”

“I was thinking the same.”

.

.

.

.

.

Time went on undisturbed, and by the dawn of the next morning,

“Haa, haa…”

Just before the sun rose above the horizon,

- Bang…!

“Adler…”

A woman with grey hair, who had ascended the stairs in one breath, her complexion pale and breathing heavily, opened the firmly shut door and immediately called out Adler’s name.

She soon lost her words and began staring blankly at the scene unfolding before her eyes.

“I love you, I love you Charlotte…”

Under Adler, lying on the bed after what seemed like cumming for the umpteenth time was Charlotte,

- Drip…

And a cloudy white fluid containing his genes was flowing out of her pussy.

“This time, you ended up being late, right?”

In such a situation, Charlotte, with a wicked grin, whispered to the uninvited guest who had found them.

“Since I’ll be the one to get pregnant first.”

Colder than ever, a deadly silence began to settle in the room, filling it up with a murderous aura.
