49. The Sin of Lust

* * *

Lust Awakens.

“That’s strange.”

Choi Si-woo, who had recently become a cute young woman, felt something was off about her body.

At first, after becoming a woman, there were no major issues. She had desired this change, and aside from feeling despair over the loss of something she had long been accustomed to, she was fine. It wasn’t much of a problem, though it did feel a bit strange.

Lately, however, her body felt a bit odd.

She wakes up feeling lethargic.

And occasionally, her lower back feels a bit sore.

“…Why does my breath smell like cigarettes?”

A strong cigarette odor lingered in her mouth, even though she didn’t smoke. She wondered about the pack of cigarettes on her drawer and called out to the Divine Sword.

[Of course, Master. It seems it happened while training with Eunha.]

“Ah.”

Eunha wouldn’t mind if she smoked; in fact, it might be necessary if she enjoyed it. After all, in this modern era, smoking wouldn’t ruin her lungs like in the past. The Divine Sword sighed at Si-woo’s reaction.

He couldn’t tell her the truth-that he had learned to smoke to be more like her, to gain her attention and build a connection with her. Si-woo found the Divine Sword’s reaction annoying and glanced at his true form.

“Why is your true form purple?”

[Ah, well…]

The Divine Sword couldn’t respond. He couldn’t admit that her transformation into a monster was his fault, or that half of his authority now belonged to her. It was embarrassing to admit, but he also couldn’t tell her that using her body would turn her into a monster.

“Hmm, what should I say… I feel strange, and it’s also kind of intense.”

Si-woo now had a strange, unique physique-neither fully human, monster, nor Divine Sword. Thus, the Divine Sword, now a “Magic Sword,” could easily accept this.

Standing in front of the mirror, Si-woo frowned at the deep purple, womb-shaped tattoo on her lower abdomen.

This was also the Divine Sword’s doing.

“But isn’t this tattoo a bit too erotic? I’ve seen similar ones in adult content.”

[It’s fine. It makes you stronger, so don’t worry.]

Si-woo sighed, and as she moved, her abdomen brushed against the corner of the dresser.

“Hiet!?♥”

She involuntarily let out a feminine moan. And there was this strange, pulsating sensation in her lower abdomen. It was tingling and made her inner walls quiver. Si-woo was confused. At first, she didn’t recognize the sensation, but having the knowledge of male sexual experiences, she realized it was female pleasure.

Now, the Magic Sword, having become one with her, quietly suppressed its consciousness, knowing her pleasure was its doing.

“What… What is this?”

Her lower abdomen tingled just from being touched. She found herself grinding her clitoris against the corner of the table, her movements instinctive and practiced.

“What is this… Haa. This feels… Huh. Ah.”

The sexual pleasure was incomparable to anything she experienced as a man. It was more desperate and passionate than any battle. A pure white sensation engulfed her mind, making her feel as though she was born to be female.

But that couldn’t be right. She couldn’t stop rubbing her clitoris against the table.

“This feeling… It’s too good.”

She couldn’t resist, even though she knew she shouldn’t. Her dolphin pants were soaked with juices, dripping steadily. Each rub brought her to a light climax, making her tremble.

She never imagined something so simple could feel this good. Perhaps women’s bodies were just strange.

After reaching climax, she felt something in her womb, as if something large had penetrated it. But she hadn’t experienced that before. It wasn’t her, but the memory lingered.

“Why… Why am I doing this… Haa, I don’t want to stop.”

Si-woo concluded that something was wrong with her abdomen. It was unlikely that a space meant for bearing children could cause such pleasure. Maybe hitting her stomach would help?

She foolishly punched her lower abdomen.

And the impact directly struck the womb that had been developed by Yoo Eun-ha, the first to claim it.

“Ik! Hyeok! Aaang!♥”

It was dangerous. Truly dangerous. The feeling was strange and perilously intoxicating. She must never do this again. Yet, she continued punching her abdomen, eventually flipping onto her back and squirting uncontrollably.

“Haa… Haa. I’m so wet. This is bad.”

She had few women’s clothes. Thinking this, Si-woo removed her pants and, unknowingly, began touching her breasts and clitoris in front of the mirror. This was Choi Si-a’s habit. Having her womb developed by Yoo Eun-ha, Si-woo enjoyed her body, lost in masturbation.

“Huh?”

Looking in the mirror, something was odd.

As a woman, the first thing she tried was seeing herself naked and masturbating. She knew her vagina well.

But what was this?

Until recently, her vagina was shy and tight, but now it opened easily, as if marked by something. Her hole, once narrow, now easily accommodated three fingers. It seemed branded, as if something had claimed it.

“Now it seems slightly open even when I’m not doing anything.”

She wondered if she should ask the Divine Sword. But it wasn’t just that. There was a feeling she couldn’t explain, as if someone had entered her while she slept.

“Ah. Ugh.”

Thinking about it made her womb quiver again. Her body, consumed by lust, craved stimulation and pleasure.

This could interfere with her future tasks.

Then, a voice spoke in her mind.

[You have Yoo Eun-ha. Take it easy.]

[You’re stronger than before. So enjoy yourself.]

It sounded like the Divine Sword’s voice.

Well, she had enjoyed her life as a man, but being a woman felt even better. Must she live as a nympho?

[You’re more sensitive as a woman, right? Surrender to your instincts as a female. It’s better for both of us.]

As a woman, masturbation did feel better. It was a fact she couldn’t deny. But she couldn’t live as a nympho.

At least, not unless she had a master who loved and accepted her.

“Why am I having such crazy thoughts?”

Si-woo shook her head, wiped herself, and put on new clothes.

Perhaps her libido was heightened as her period approached. Women’s desires often intensified then.

But it seemed extreme. She might need to prepare for her period soon and relieve this overwhelming lust.

“But I can’t go to Eunha or sleep with a man.”

As a woman, sex with men was impossible. She couldn’t let her body rule her. So, she decided to buy adult toys.

Some female cadets couldn’t date and, stressed by their environment, carried dildos. She had seen this before, even among Han Su-ji before her regression.

She recalled a shop in the academy’s back alley and went there, wearing a wig.

Upon entering, a strange, sweet scent filled the air, and explicit sex toys lined the shelves.

“Oh, look at this cute young lady.”

“Hello.”

She bowed to the shop owner, who seemed to run the adult store, and looked around. She found the women’s section on the right.

There were dildos of various types, G-spot vibrators, jelqing devices, and anal plugs. The latter seemed too extreme.

Gulp

Seeing the penis-shaped objects made her want to insert them immediately. Something inside her felt empty and yearned to be filled.

But honestly, she craved more than just a dildo-something to stimulate her clitoris or strike her womb.

“I’ll buy a few things.”

As a man, she had never bought an onahole, but as a woman in this state, she couldn’t resist. Her instincts urged her to buy and try everything.

“Hmm, miss. Should I buy all of these? It seems like your first time. Why not take it slow?”

The owner recommended a small pink vibrator.

Embarrassed by the recommendation, Si-woo looked down, and the owner, finding her cute, showed her more items.

“No, it’s not that. Um…”

“Hm? Don’t be shy. Tell me? This is just between us. This is incense. It’s similar to aphrodisiacs but a bit different. If you light it in your room and masturbate, the climax is incredible. Smell it.”

Si-woo, feeling lightheaded from the incense, barely maintained her composure.

If she gave in now, she’d become a nympho, lost in lust.

Should she say she wanted to try everything? Or hold back?

Money was no object. The items here could be bought with what she earned from selling dungeon drops.

But she worried about becoming addicted to masturbation. Her mind had become fixated on her womb’s sensations.

Then,

Kya!

Two burly bald men burst into the shop.

“What’s going on? What is this? Huh?”

“Oh, so two bitches are running this shop.”

Si-woo, mistaken as a store clerk, dropped the dildo in her hand and panicked.

“Who are you? Why are you causing trouble in someone else’s store?”

“Trouble? Fuck you. Hand over all the money!”

They even tried to rob an adult store.

“Hm, you’re pretty. I’d love to fuck you.”

She should fight back, but the incense had clouded her mind with lust. Disoriented, her hair was grabbed by the thugs, and she couldn’t resist.

When she finally looked up, the situation had escalated.

“Look at this bitch!”

Pak!

Si-woo, struggling in the thug’s grip, felt a surge of magic in her womb. With all her might, she delivered a magic-infused punch to his gut.

Her womb, experiencing intense stimulation, trembled and spread pleasure throughout her body. Starting from her abdomen, the sensation ran up her spine to her brain, imprinting an overwhelming pleasure that made her fully aware of her identity as a woman.

Pshut-Pshuuut!

Si-woo, held by the thug, trembled her waist rhythmically, squirting before freezing in place.

“Ah, this is it. This is what I wanted.”

She had felt something missing when she did it herself, but this was different. Letting go completely and being punched in the womb with a magic-infused fist-this was what she needed. Si-woo finally felt a satisfying climax, her mind exploding with relief.

This liberation was her mental acceptance of being a woman with a womb. Of course, her womb was developed for something other than childbirth, which was a big problem, but she didn’t care now.

But it was short-lived.

After savoring the pleasure for a while, her hair was yanked by the thug, causing her pain.

“Hey, you cunt. Are you crying?”

“Hah! Did you piss yourself from fear?”

“P-please, take the money and let her go!”

“That’s up to you. Bring all the cash!”

The thugs, misunderstanding the situation, continued to grab Si-woo’s hair. The store owner, unable to help, went inside to fetch more money.

Meanwhile, Si-woo, angered by the interruption of her climax, vented her frustration.

“Ah, damn it.”

“Huh?”

“I was really enjoying myself, but these bastards ruined it.”

Si-woo, who would never normally speak this way, was mocked by the thugs.

“Is this bitch crazy?”

“She must be out of her mind!”

Swish!

The thugs, attacking her recklessly, were decapitated on the spot. Si-woo felt no excitement, merely eliminating those who interrupted her pleasure.

“Huh? What happened here? What about the thugs?”

After the situation ended, Si-woo dragged the thugs’ bodies outside, unable to explain the scene to the returning store owner. She had no choice but to act like a typical academy student.

“I’m a student from Hanseong Academy. They were too vicious, so I just killed them.”

She could have captured them but chose to kill out of sheer frustration.

Si-woo, once lenient with villains, now decapitated them easily for interrupting her climax.

“They started it, after all.”

“I see. I’ll contact the Association and have this handled immediately. Please don’t worry.”

The store owner, unaware of Si-woo’s true strength, thanked her and gifted her all the adult products she had picked, believing she had saved her life.

The real problem began afterward.

Si-woo, developed by Yoo Eun-ha and consumed by lust, became addicted to masturbation.

“Haa… Haa. The biggest one feels just right.”

Si-woo erotically licked a massive black dildo, which she had inserted into herself, as juices dripped out. Lost in lust, she spent her days emitting pheromones as a woman, becoming a vessel for the Sin of Lust.

“Hiet!? Ah. Aaang!♥♥”

Choi Si-woo, now a woman and weaker to lust and temptation than before her regression, couldn’t resist the encroaching Sin of Lust.

Her body, beyond responding properly to penetration, was consumed by the Sin, which infiltrated and corrupted her.

[The Sin of Lust has awakened.]
