Ah yes. Mona Lisa, the famous portrait painted by Leonardo da Vinci during Italian Renaissance period. It has nothing to do with some moaning-climbing librarian or the one that makes every R34 artist to draw her based on her outfit alone...

*Rustle**Rustle*

*Ka-chink*

A single Mora coin dropped into her palm.

So light.

And so dejected just from looking at it.

I guess I've to settled with those fungus in this end of month once again…

After another heavy sigh, the astrologist put the coin back into her pulse.

Mona Megistus, meaning 'The Great Astrologist Mona', was her name.

The distinctive appearance of her was the purple and black leotard with gold lining, along with it was a witch hat (which somehow had more fabric than the rest of her wardrobe).

It has been some time after the first meeting with the Traveler whom Mora viewed them was an off-worlder.

In order to complete the task given from her master, Mona has taken her own course of action by traveling to Mondstadt, to meet up with the teacher's rival's disciple.

Unfortunately, Mona could not foresee such a ridiculous fate when she met Klee.

After some miscommunication with the girl in red, Mona accidentally read a certain book that turned out to be her master's diary.

"I-I'm done for. The thing inside this was the dark history of her youth... she will kill me if I go back like this..."

Thanks to that incident, Mona has lived in Mondstadt as a refu…a resident! This effort was to avoid the wrath of her master, and hopefully able to outlive her.

After living in Mondstadt for a few months, Mona had adapted well to the life in the city. The people were friendlier than Liyue. Everything was affordable for one's average income.

To Mona, however, if only she could control her impulsive on buying certain astrology-related materials, regardless of its cost.

Needlessly to said, every purchase Mona made had affected greatly on her daily needs, especially coming to food and rent.

Today was another peaceful day like any other day before, that means, no commission.

After learning this from Katheryne, the receptionist of the Adventure Guild, the astrologist limped herself back home.

"Uh, what should I do? I have no money for this month's rent. Should I try to avoid him when I see him?"

"Oh hey Miss Mona!" A voice called out just before she reached out for the door.

"Gaah!" Mona yelped momentary before she turned around and greeted the man properly.

"Oh hello, Mr. Goth…"

Speak of the devil!

"I'm sorry! Please give me a few days and I will pay the rent!" She put both hands together, begging him.

The house she's staying was a place that she reluctantly rent from this man after she managed to break off the magical seal.

Even though with the Traveler's advice: 'Save a little here, scrimp a little there' Mona wasn't able to control her buying because her sense of pride.

"Is the commission's reward not enough for your daily need?"

"Oh no, Mr. Goth...uhm…"

Because I've just blew it on buying another crafted item…

"If you have trouble in finding a commission. Perhaps I could introduce you to a work to earn some money?"

"Oh…really? You mean it? That would be great-eh-hem! Y-Yes…what do you have in mind?" She controlled her excitement.

"Please follow me."

Happily, she followed him behind.

... ... ...

... ...

...

"You know, Miss Mona. I couldn't help but seeing your outfit. It reminds me the old days of Mondstadt."

"The old days of Mondstadt?"

"Even though many would say it's a dark age, but it's certainly a wild ride for a fool hardy like me."

"A fool hardy?"

"Prostitutes."

Mona could only blink her eyes a few times by such word.

"A lot of them, standing on these streets, in those alleys, blowing the kiss in the air, seducing the men. The lambs were filled with pink to blend in with the atmosphere."

"The hotel I own was actually used to be a brothel, owned by my great grandfather."

Mr. Goth looked over an alley.

"This alley right here, was the place where the boys, young and foolish, and horny spend their money to get those booties."

"I see…"

She looked down, examining her appearance once more. Her outfit, Flowing Fate, was a light outfit and it helped with her [Illusory Torrent] talent for exploration and combat (didn't help much when she hit the edge of the stairs though…).

Like Mr. Goth said, it showed the curviness of her body.

With awkwardness lingering in her mind, the two soon arrived to Mr. Goth house.

After entering through the living room, he led Mona to a certain room that had appeared to be a drawing room.

"I hope you don't mind, can you take off your clothes. please?"

"Eh?"

EEEEEHHHHHHHHHH?!

However, what Mona's scryglass showed that the man didn't have any vulgar thought.

So perhaps the reason he asked her to undress was for...painting?

She noticed there was a canvas.

Maybe he needs me as a model?

There was a bit of conflicting in her. However, Mona soon did what he told.

"I...I'm ready." It's embarrassing since this was a first time for her. Never before she had shown her naked body to someone else. But since it's for the work of art…she would make an exception.

"Oh good. Let's stick this onto you then." The old man turned around, with a certain thing in his hands, which shocked the naked astrologist.

"Wh-what is that?!"

"It is called the Devil's Root. It's a type of plant to boost the men's vitality for the fun at night."

"And the most twisted part about it that it wasn't grow on the soil like any other plants, but it feed on female body fluids."

"Female…body fluids…?"

"See for yourself." Without waiting for her response, or even her consent, Mr. Goth had put the root's end on Mona's very place.

"H-hey, wait...!"

To her horror, the thing twitched on its own, as if coming to alive and soon the little roots invaded inside Mona.

"Nooooo! Get it off me! This…wicked thing…!"

She grabbed it and yanked it.

"Gyaaa!"

W-what is this?! I just place my hand on it and I can feel the electricity shock my entire body.

The sudden shock made Mona's legs went numb and rendered her to drop on the floor.

"Are you alright? You shouldn't pull it out forcefully."

"Wh-what happened to me!?"

"It had assimilated to your clitoris. It surely made you feel like you have become a male."

Much to his explanation, Mona stared at the phallus-liked thing with horror.

"H-How do I get it out?"

"Make it grow." He answered.

"It will grow from consuming your fluids."

"My fluids…what kind…"

All of sudden, her crotch felt ached and...

Uh…it's leaking! My crotch is…wet! My heart is beating faster. And my body is…hot!

"Once it fully grown. It will detach from you on it own."

"H-How long do I have let it stick onto me?!"

"Three days."

"Three days!?"

"But I heard there's a faster way to make it grow in just one day."

"T-tell me!" She almost begged him.

"Semen."

"Eh?"

"It was a cruel idea from the old aristocrats back in the day, place those devil roots onto the poor girls, and then play their bodies. Some even said that it was replacement when they couldn't find any beautiful young boys."

"Then…this is your plan all along…?" Mona feared that her scryglass had wrong about him.

"Oh no, an old age as myself couldn't handle a young woman like you. I would surely die out of heart attack. Ohoho!" His nonchalant speaking left her speechless.

"But I can introduce you to my son if you like."

"…"

… … …

… …

…

"I can't believe how…how…shameless he was…"

The flustered Mona muttered once she had exited from Mr. Goth, with her chastity intact…along with one additional thing attached on her lower body.

"He even gave me a bag of seeds of it."

'If you can grow them more, I'll pay for them handsomely.'

Her first thought was to throw them all into the trash bin, but after a thought…this was indeed an easy money, although it would take too long to earn it.

She needed to get more information about this Devil's Root.

First thing first, however, how should she deal about the…bulge?

…

…

"Oh hello, Miss Mona." Flora, the young florist, greeted Mona. She then spotted something was different about her.

"Why do you have a scarf by the waist?"

"Oh you know…I heard it's a trend. Just want to try it out myself. Hahaha…"

"Anyway, I would like ask you something…"

…

…

No good…another dead end.

Even after going out of the city to meet Chloris, Flora's older sister, in hope to learn more about this Devil's Root, yield no result.

They had no knowledge about such wicked plants. Either it's a contraband, or it's their young age.

Do I really have to let it stick on my body for three days straight?

No doubt it would...hinder her a lot.

Semen…a man's semen?

Do I really have to...?

The thought of her asking someone: 'Please, give me semen!' It made her face turned red.

"Ohmigosh. I must be crazy..."

Maybe I should ask Albedo. Hopefully he can come up with a solution…

While in thought, Mona heard…a moan.

"…where is that coming from?"

Using the [Illusory Torrent], she sunk into the ground and moved toward the noise.

Is that…Miss Lisa?

Is she…doing what I think she's doing?!

To Mona, Hilichurls were primitive monsters. She could handle them easily with the commission she had before.

But seeing someone who was fully capable in dealing them, had submitted to them like that.

It was beyond. She didn't think her spyglass would show up something like this either.

A human and a monster...together? Are my eyes deceiving me?

While many questions was running through the head, Mona didn't do anything than just watch.

"Haa…haa…"

It feels so hot…not just this Devil's Root but also my…

Oh no…this thing…is responding…it's consuming my body fluids!

Mona quickly removed herself from the scene and retreated to a certain bush.

The swollen part beneath her leotard was getting more and more uncomfortable, as if it's demanding to be free from this...restraint.

"Should…should I take it out?"

"Take what out, dear?"

"GYAAAHHH!" Her heart was almost jumped out of her chest.

When Mona turned around, she was only shocked to see the same person who had committed such...immoral deed was now standing before her.

"H-How did you?"

"Oh my, I didn't mean to scare you like that, cutie."

"Scare me…? W-what about you!? Why are you doing such…such thing?!"

"Never mind about me. What's that thing behind your clothes, Mona?"

The astrologist reflexively tried to hide it, but the librarian already saw the protruding part on Mona's lower body.

"Is that…? Oh my. Oh my! Is that the Devil's Root?"

"You…you know about it?"

"I've read about it a bit. I thought it was some wild imagination though, not a real thing. Until now."

Without asking for permission, Lisa's gloved hand reached out and touched the swollen part of Mona's blue leotard.

"No stop!"

Her hand didn't stop. After feeling the glans of the male-like sexual organ, she moved down further, feeling Mona's original sex part.

"Don't tease me there!"

"Oh my! A cock and a pussy. Two packages in one. You are quite lucky, Mona."

"Ah…hah…"

My heart's pounding like crazy. This is too much!

"It's bad to keep it under your clothes like that. Here, let me help you."

Mona's outfit's crotch area was cut open. Revealing her pussy lips along with the plant that attached onto them.

"Oh my~! It looks so cute!" Her eyes were glistering.

At this point, Mona was scared by Lisa's spirit. She had never seen someone would be this excited.

Once more, Lisa skillfully grabbed Mona's…phallus and stroking it.

"No…wait!"

"Don't be scared."

Up and down. Up and down.

Lisa's hand started stroking Mona's phallus in a steady rhythm. Not too fast. Not too slow.

The stimulation brought an odd pleasant sensation throughout her body.

By the seven, why does it feel so good? She is too good!

No! This isn't Lisa's fault. It has to be the Devil's Root's fault!

Regardless, Mona couldn't deny this feeling as it was...building up, to the point she couldn't hold it in!

Something is coming out!

"Cumming…! I'm cumming!"

The astrologist's hips jerked upward, as her entire body was trembling.

"Oh my, you came? But I didn't see any spunk coming from you."

Still holding the phallic rod in her hand, Lisa examined closely at Mona's lower body, especially at the joint between her sex and the Devil's Root.

A finger touched onto Mona's wet vagina, sending electric to her head.

"Ahh! Stop! Please…I just came…"

"Oh, I see! This thing is your own clitoris. It makes you feel like a man, but since you don't have testicle, you can't produce semen on your own."

"That…is too much information."

"Hmm…what to do…? Oh, I know!" Lisa came up with a solution.

She then made a whistle.

Soon, a certain group, consisted of four primitive humanoid monsters, was summoned to their location.

Mona froze, figuring out Lisa's intention.

"Hilichurls...You want me to do it with a Hilichurl?!"

"Well, it would be quite a lot of trouble if you ask someone in the city, right? Everyone knows your face well, Mona. Especially that outfit."

"Again with the outfit—ahh!"

Without a warning, Lisa had put her mouth closer to Mona's vagina and invade it with her tongue.

"Your tongue…I can feel your tongue!"

"Is it good?"

"Y-yes, it is! But please, I just came…wa-hah!" Her feet lifted off from the ground as they're twisted inward.

"I guess this is good enough."

"For what…No...you can't possibly mean! No! Not like this!"

Ignoring the girl's distress, the witch motioned one of them to come closer.

"Come on cutie, let's give this girl some thick milk of yours."

As if it's a natural thing to do, the humanoid revealed its sex member to the female, who only wide-eyed before the happening.

The Hilichurl gradually filled the entrance.

It's in!

Blood trickled from where they're joined.

It's in! It's inside me!

It's touching my womb.

The filthy thing of a Hilichurl is touching my womb!

It's supposed to be hurt…

Why I am feeling so good?

"How does it feel, Mona?" Lisa smiled, looking at the copulation between the human and monster.

"I don't know! It's so hot down there!"

"Why...it's supposed to be low tier monster...How does it move so good?!"

"Most of them are not smart, but they've got strong bodies."

"[Hey Gary. Want to go for her ass?]" The Hilichurl asked his buddy.

"[Ehh, should I? This human got a dick, man, isn't it a guy?]"

"[It's a female.]"

"[A female with a dick!]"

"[And I'm doing her pussy here!]"

"[How about you, Greg?]" The other asked.

"[I've got wife and kids, dude. I ain't no cheater. I'm going home.]" The named Hilichurl packed his stuffs and walked away.

"You can release it whenever you want." Lisa told the humanoid as he was pistoning toward Mona.

Where…? Inside?

Through my ripped hymen?

It's getting larger and harder!

Is it going to release?

It'll reach the womb!

"No! Stop! Make it stop—!"

Her pleading came too late as the lukewarm fluid burst forth within her body.

"GYYAHHHHH!"

The excess overflown, spilling out around.

"Oh look at that, your little penis is growing. It's like filling the water into the bottle."

Mona looked down, checking the fact.

Not only her vagina was numb, but the thing had felt heavier and kept throbbing hard.

"It's not a good manner if you don't clean the dick that has just put inside you. Come on."

Lisa guided Mona's head closer to the wet black cock.

I didn't think I would give my first kiss to this filthy thing…

"It's tasty, right?"

"This is...distasteful..."

"I think you've come to appreciate the taste of a Hilichurl."

"[Do it man.]" The same Hilichurl asked his buddy.

"[But she's got a dick…]"

"[So what? If there's a hole, there's a way.]"

"[Okay fine! Not because I'm that desperate!]"

"[Yeah. Yeah.]"

"Huh? What are you...kyaa!?"

Mona's lower body was put in the most shameful position, where her bottom was in full display.

A chill run through her back as she saw the second Hilichurl about to commit the deed.

"No! Not my ass! Wait…gukk!""

Her defenseless butt was soon penetrated.

Mona clenched her teeth, enduring the sharp pain.

"Keep breathing dear. Otherwise you will get faint."

"No…this is too much...!" Tears soon started dropping from her eyes.

"A girl as cute as you ought to enjoy anal."

"Where is that coming from?!" She almost wanted to lunge at her if she wasn't...being occupied.

Without a warning, one of her leg was lifted up, exposing her entrance as the second shaft made its entering.

"Ah no wai—!"

The scream was louder than the previous one.

"My belly! It's being crushed on both sides!"

The way they filled me up…I never thought it's possible.

Without pulling out, they yanked one of her legs in the air.

"Fufufu, what a sight."

The semen that spurted inside her vagina was slowly consumed by the Devil's Root.

The size of it grown overtime. And in a ridiculous pace.

Lisa and Hilichurls were astonished to see Mona's thing had extended about a foot long.

"Oh my. Oh my~!" The size didn't intimidate her. It was the opposite.

The purple witch took the glans with her mouth happily and licked it all over.

The air filled with wet, nasty sound.

Lisa's mouth is so warm…

I can't believe this. But I want to cum. I want to cum inside her mouth!

I need to let it ejaculate or else I'm going to go crazy…!

"Don't cum just yet, Mona."

Her voluptuous breasts soon sandwiched Mona's rod.

"Ahhhh! It's cumming. My cock is…!"

"WAAHHH!"

The semen spurted all over.

"Now for the finishing touch."

In one motion, Lisa put herself on top of Mona. The Devil's Root was still throbbing with energy.

"No Lisa! Wait, I just came…! Ahhh!"

The librarian paid no heed as she crouched down, accepting the phallus inside her.

The assault continued on. The joint between the two females were leaking out their own love juices.

To give more stimulation, Lisa kissed Mona and groped her breasts.

"Mmn…! Hgm!"

"Nooo! I'm cumming!"

With the fluids that remained inside the Root, Lisa squeezed them all out.

"Even though I just came, I'm cumming again!"

"Kuh!"

Mona shivered, her hips trembling as she climaxed. Her head started to feel light.

"You came hard, Mona. I don't think any man in the city would be able to compete with you."

"But you need some milk after that."

"Come on boys. Keep thrusting your dirty cocks inside her."

"Gah gah!"

The feeling of being penetrated. And then the feeling of penetrating.

It was something that Mona couldn't describe, even if she had foreseen it.

"Be honest with yourself."

"You want them to go rougher on you."

With those words like a chanted spell, Mona began to beg them to do her harder and deeper.

"Please give me your semen. As much as you can!"

Lisa and the three hilichurls swarmed over the astrologist.

While each male was filling up Mona's three certain holes: The pussy, the ass, and the mouth.

As for Lisa, she was serving Mona's second sex organ diligently.

The feeling of having a dick is so good! To be able to ejaculate like that…

Over and over. Again and again. The girl who became a man today had ejaculated another cum shot.

If this keeps up, I will go silly!

In her own trance, another peak of climax was reached.

"Aahhahhh! Cumming! I'm CUMMMMINNNNGG!"

Shudders run through Mona's entire body as she climaxed.

"Mhpm!"

"Oh my, it came out."

"Eh?" Mona didn't catch that.

"Your dick came out, dear." She repeated, looking down at the root.

"Eh…eehhh?!"

True to her words, the crotch area was lighter...but there's still a problem with the fluids that was gushed in her vagina.

"It must have its filled."

"Oh well. I guess that's that. I think everyone had their fun."

"Thank you, Mona. It was very good."

Lisa crouched down near to the tired Mona and said this.

"I hope you can keep this a secret between us."

The Hilichurls and Lisa then started packing up their belongings.

"Wh-where are you going?" Mona asked, seeing Lisa was about to walk in the same way with the humanoid monsters.

"I'm going back to their camp. Since I have promised to the boys."

"You are going to…stay with them?"

"Of course. It's my day off." Lisa flatly gave the answer. "Take care of yourself, cutie."

Even though Mona should be glad that it's over, but…what is this…kept aching inside her?

"W-wait!"

She called out, gaining the attention of the departing group.

"Can…can I come with you?"

"I need to...grow some more of these..."

Mona opened up the bag that Mr. Goth has given to her. There're eight more of them.

With a sense of curiousity and anticipation, Lisa placed one onto herself.

"Oh my! This is…something." The Purple Witch was fascinated that she had a male member grown on her body.

"Jean would be so delight if she sees this. Oh, speaking of her…"

The Hilichurls looked at each other.

"[This is getting out of hand. Now there are two of them.]"

... ... ...

... ...

...

I can't believe that Lisa would just leave me out in the wild like that…

It was the game that Lisa has in mind, by exposing the Acting Grand Master to the nature, without a single piece of cloth on her body.

There was supposed to be a time limit.

However, after a long hours of wait, Jean had no choice but made her way back to the city. It was very fortunate to her that she didn't get spot.

By the time she had made it through the back gate, it was late at night.

In the darkness, she stumbled upon a certain cloak figure.

She landed on the ground with her bare butt. Just before Jean could run away, the figure was somebody she did not expect to see in this city.

"An Abyss Mage?!"

The named enemy started chanting his elemental attack.

Oh no! I have no weapon or anything to defend myself!

When she reflexive put up her arms, bracing for the incoming attack.

A painful cry was made.

It was not coming from Jean.

When she opened her eyes, she saw a black figure had attacked the Abyss Mage with a claymore.

There was an urban legend circulating in Mondstadt about a vigilant known as The Darknight Hero, however, no matter how you would look at it. That person was…

"Diluc…" Jean spoke the name.

The long redhead turned around.

To her anticipation, the person's expression was as shock as Jean was.

"J-Jean?" She, yes, she spoke the name.

Before the Acting Grand Master's eyes was the gorgeous looking red-haired female clad in black attire. Her name was Diluc.

I did not want to do this. But Diluc, you have ruined my 50/50. You shall suffer the wrath of my Rule 34! And Rule 63.

NGL, the gender-bended Diluc is hot AF!
