Sothing within had been changing for quite so ti—I had known that much.
I had thought about wanting to beco a woman. But it was just a fleeting wish, sothing I never imagined would actually co true.
After becoming a woman, many things changed. n no longer looked at as a revered wielder of the Divine Sword. Instead, they scanned my face and body like predators, their gazes dripping with lust as sinister smiles crept across their faces. Won, on the other hand, stared at with eyes filled with envy.
Before I realized it, I had started to gain confidence in my appearance. I dismissed the n with a contemptuous sneer, as if to say, You dare think you’re worthy of ? And I mocked the won’s jealous stares, taking pleasure in their resentnt.
Still, I reminded myself not to forget who I truly was. To hold on to my identity.
And yet, in the end, I failed to control this depraved body of mine, giving in to pleasure. The "Sin of Lust," a temptation that should never have touched , took root and gave birth to an entirely new persona.
That persona was a version of wholly corrupted by lust—a female driven to utter ruin.
I lost myself to that persona, spiraling out of control. Even the Divine Sword, long dimd and deprived of its sacred power after Eun-ha’s intervention, could no longer be wielded.
As a result, when the Divine Sword relinquished control of my body, Lust began its rampage.
The only fortunate thing, as Eun-ha had pointed out, was that this body, though awakened by Lust, had yet to experience any extre sexual pleasure or use its full powers, leaving it comparatively weak. Lust seed to be aware of this limitation, and, to make matters worse, it had the audacity to entertain ambitions of conquering even Eun-ha herself.
It all ca to a head when, unprepared as it was, Lust foolishly provoked Eun-ha, declaring its intent to sleep with another man just to rile her up. The result? A thorough beating.
While Lust may have been weak at that mont, it was still a sin, and sins themselves were powerful enough to hold their own against S-rank hunters. Yet Eun-ha didn’t just defeat Lust—she beat it into the ground like a dog.
Thanks to her relentless pumling, I sohow managed to regain my senses.
But Eun-ha’s intentions went beyond simply putting Lust in its place.
Eun-ha had a plan—to rge with Lust, fully integrating the two of us into one. She intended to turn into the very embodint of the Sin of Lust.
At this point, with even the Divine Sovereign having fallen to corruption, I wondered if there was any purpose left for . Still, I couldn’t give up. I clung desperately to the idea of preserving my sense of self, my identity.
But never in my wildest nightmares did I imagine that Eun-ha would take it a step further and begin "developing" my body.
And yet, there was a part of that… felt it.
Every ti she struck my lower abdon, a strange, maddening sensation spread inside , making tremble. It wasn’t just pain—it was an itch, an unbearable, electric thrill that seeped into my core, staining my mind with thoughts no better than those of a bitch in heat.
No, this wasn’t even the ordinary mind of a woman. This was sothing lower, sothing degraded—an existence completely consud by Lust. A filthy, depraved being who could feel pleasure even while being struck.
I couldn’t accept this. I told myself that over and over again, trying to reject the grotesque reality. And yet, my body betrayed , shuddering with joy even as the blows rained down on .
But there was sothing missing.
The satisfaction wasn’t complete. I felt blocked, as though sothing deep within refused to let go. This resistance—this recoil—ca from my refusal to embrace Lust as my identity, to give in to the sin entirely.
If I accept this, there’s no way I can save the world.
That thought burned in my mind, keeping clinging to whatever scraps of humanity I had left. But Eun-ha’s words, each one cutting deeper than the last, began to chip away at my resolve. I could feel myself breaking, piece by piece.
"That's enough. You've done well. Now, it's ti for you to find your own pleasure."
Find my own pleasure? No. That can't happen. I fought tooth and nail to reverse that ruined world. It's my responsibility.
And yet, sothing inside scread, urging to listen to Eun-ha's words, as if my own mind had turned against .
—Just accept it already.
—You're a woman now, anyway.
—Sure, getting nailed by a cock might sound extre, but if it's Eun-ha, I don't mind at all♥
—I’m you, too. Stop tornting yourself.
—You think only you can save the world? Only the Divine Sword can do it? You’re wrong. Leave it to Eun-ha.
Lust whispered, coaxing , begging to give in.
My resolve was weakening. With every mont, I could feel my womb—a part of I couldn’t deny any longer—proving my femininity. Every ti Eun-ha’s touch made tremble with sensation, it beca clearer. My body had already surrendered to her, acknowledging her as its master.
I couldn’t hold out anymore.
Honestly, I’d tried so hard. Before my regression, I thought I could protect the world while cherishing the won I loved. But in this life, I gave up everything—love, desire, my personal happiness—to focus solely on saving the world.
But now? If it’s co to this, maybe I should just leave everything to Eun-ha.
With the power of the evil dragon she wields, perhaps it’s possible. Maybe she can accomplish what I couldn’t.
"Is it really okay…?"
The words slipped out before I could stop myself.
“That’s exactly it. Now, you beco a bitch who follows soone more reliable. A slave to them. Be honest—you’re already a bitch. Don’t feel ashad of having been a man before. Just embrace it. There are plenty of won like you, so it’s not strange at all.”
Each ti I heard Eun-ha’s voice, my lower abdon quivered uncontrollably.
My womb throbbed, betraying with its every beat. A woman’s body was ant to be molded to fit a man’s, yet here I was, being reshaped to fit Eun-ha instead.
Even sothing as intimate as scissoring sent waves of overwhelming pleasure through .
"Hnn—!"
“What’s this? Why are you trembling all of a sudden?” Eun-ha teased, her voice dripping with amusent.
"I-Is this really okay?"
The words slipped from my lips, unbidden.
"Exactly. Now you’re going to beco a proper bitch, soone who follows soone more dependable. A slave, obedient and true. Be honest—you’re already a bitch. Don’t feel ashad of once being a man. Embrace it. There’s nothing strange about it; there are plenty of won like you."
With every word Eun-ha spoke, my lower abdon trembled uncontrollably.
My womb pulsed, beating with a rhythm I couldn’t deny. A woman’s body, designed to complent a man’s, was now remolded by Eun-ha, reshaped for her alone. Even the intimate sensation of scissoring—sothing I would have never imagined—was intoxicatingly pleasurable.
“Hnn—hah?”
“Oh? What’s this? You’re trembling all of a sudden?” Eun-ha teased with a sly smile.
I couldn’t respond. My body was shaking too violently, and the trembling in my lower abdon was impossibly good. My legs quivered, struggling to hold upright as waves of trembling pleasure surged through . Slowly, ever so slowly, I felt the build of sothing incredible, skin-tingling, as I approached a peak I could barely comprehend.
“My… my womb is trembling. Hnn… Nghh… Ahh…”
"That’s it. Let go of your reason. It’s ti to relax and beco mine. No longer the protagonist, but a heroine—a bitch wagging her tail at my side."
I couldn’t hold out any longer. It was impossible now.
When she spoke of making hers, my heart trembled, my womb pulsed harder, and I knew I couldn’t resist.
That was it. I didn’t need to carry this heavy burden alone anymore. I didn’t have to be Choi Si-woo, the Divine Sword wielder, or a hero. I could just be Lust, her woman, living for her and surrendering to the pleasure she granted. Giving her my body and soul, just as a woman gives everything to the man she loves.
But to , Eun-ha wasn’t just a woman. She was the strong, dominant male who had conquered the woman that Choi Si-woo had beco, body and soul.
I couldn’t resist anymore.
Eun-ha told not to be a wielder of the Divine Sword or a hero but to live as her woman, to beco Lust.
If that’s what my master commands, I’ll obey.
I decided to accept it all.
I am no longer the Divine Sword wielder.
I am the Sin of Lust, Choi Si-woo.
At that mont, Lust, which had been waiting inside , began to entwine itself with completely, filling every part of my being.
"If you say it like that, I can’t hold back anymore♥," I whispered breathlessly.
—See? You should’ve done this from the start. It feels good for both of us.
The man I once was—Choi Si-woo—was shattered into pieces, dissolved completely under the weight of the sin. In his place, a new Choi Si-woo erged. A woman. A vessel for Lust, finally accepted and complete.
In that mont, the pleasure I had held back for so long crashed into like a tidal wave, pulling into its depths.
Letting go of reason, the world looked entirely different.
Thump-thump. Thump-thump.
Dark, imnse energy surged out from within , covering my body like a tide. I could feel every cell in my body being rewritten, reshaped. Even the slightest brush of wind against my skin sent shivers of climax through , making my womb tremble.
“Haa… Haa… Haa…”
Pleasure I could have never felt as a man. Not even during those private monts of self-discovery. No, this was on an entirely different level, beyond anything I’d experienced before.
Was this what it felt like to beco a monster? Or perhaps it was because I had accepted Lust completely. I could feel my human heart being replaced by sothing else—a core, throbbing with power.
As Eun-ha desired, I was falling further and further into corruption.
To give up my humanity, to offer my body and soul to the woman I adored—was this what it felt like? My mind went blank, the world around turning white as my perception shifted entirely.
With a sudden, explosive sensation in my lower abdon, sothing burst forth, spilling out.
“Hah… Heheh… Hehehe…”
Why had I resisted this for so long?
This electrifying sensation coursing through my entire body, this climax—it was overwhelming.
Accepting my monstrous transformation opened the door to an entirely new world.
Becoming a monster was deeply tied to emotion and pleasure, which explained why female hunters and villains were more prone to these changes than n. If this was what it felt like, perhaps it was natural.
Monsters are drawn to those stronger than themselves. They submit and seek affection from them. So even consu humans they love, desperate to fill that void.
Now that I had beco Lust, I understood.
This boiling, overwhelming power surged within , and alongside it, the certainty of my submission to Eun-ha.
The transford knew one truth: Eun-ha wasn’t just my master—she was soone I had to love and yearn for with every fiber of my being.
Before I knew it, I was kneeling before her, bowing naturally, as if it were my rightful place.
“The Sin of Lust offers her body and soul to her Queen♥.”
***
Suddenly, I saw sothing terrifying.
The dark energy that had spilled onto the floor began to writhe like persistent tentacles, clinging tightly to Choi Si-woo’s body. One by one, they latched onto her, encasing her as if forming a suit. Then, it crept up her face, transforming her in a horrifying way.
Her mouth stretched all the way to her ears, lined with fangs so sharp they were almost alluring. Si-woo’s face, now covered in that viscous dark energy, bore a massive red eye, vertically slit, glaring nacingly from her forehead.
"But damn, that’s fucking hot."
That latex-like suit perfectly accentuated Choi Si-woo’s distinctly feminine figure, and I barely managed to suppress the urge to reach out and touch it.
After so ti, the dark energy, now resembling latex, was completely absorbed into Si-woo’s body, and her face returned to its original form.
It seed like this wasn’t just a manifestation of Sin of Lust but a new ability she had acquired.
Most likely, this power was focused on physical enhancent. Judging by her transformation, if Si-woo were ever pushed to the brink in a fight against a stronger opponent, this monstrous second phase would erge.
Her violet eyes, now gleaming with a seductive heart-shaped shimr, sparked a dangerous desire, an almost irresistible urge to lick them.
“The Sin of Lust dedicates both body and soul to Her Majesty♥!”
“So Lust is the dominant personality?”
After all, the rampaging Lust from earlier was simply a fusion of Choi Si-woo and the Sin of Lust itself. This was probably her true form all along.
Choi Si-woo, now fully embracing the pleasure of being female, had completely rged with Lust. Whatever remnants of her forr male identity had been completely consud, leaving her as a fully corrupted, monstrous heroine.
"A lewd voice like that suits you. That said, I don’t want anything but either playful banter or proper respect from a heroine."
"Okay."
Damn, should I just devour her for real?
"How about a sticky, dirty round of sex?"
"Okay♥"
The sticky dark energy dripped back onto the floor, pooling together to form a black, ominous space.
Outdoor, sticky, and overwhelmingly intense monster sex? Just the thought made my body tremble with excitent, as though my very core was shaking in anticipation.
"Does this dark energy spill out whenever you get aroused?"
"This transformation… it's all because of you, Eun-ha. You need to take responsibility for ."
Her face, twisted with lust like soone consud by desire, suddenly shifted to mimic the helpless plea of a woman irresponsibly impregnated. That was it—I couldn’t hold back anymore.
I gently caressed Choi Si-woo’s cheek.
"Of course. If I don’t claim a woman like you, who will?"
More than anything, I had claid one of the Seven Deadly Sins for myself.
Now that Lust was mine, it would serve as an even greater power in battles against the other Sins to co. Who the final boss would be was still a mystery, but one thing was certain: Choi Si-woo, the wielder of the Divine Sword, would grow stronger with the power of sin coursing through her.
Squish, squish.
When I touched her, exploring her most intimate place, it was clear she had succumbed entirely to Lust. After several peaks of ecstasy, her body was openly, helplessly dripping.
To think the wielder of the Divine Sword had fallen to this state. She was no longer the sacred warrior—she had beco nothing more than a depraved woman consud by desire.
Well, it was Lust, after all. This outco was inevitable.
"Your juices are flowing so freely. To think latex play would be possible with you… You’re the ultimate female. I like you. But seriously, are you okay with this? If the Association finds out, it’ll be trouble for you."
"As long as Eun-ha likes , that’s all that matters♥"
Who would ever believe this was the sa Choi Si-woo?
"You cheeky little thing. Cover your body with that dark energy."
Suddenly, the thought of latex play from earlier beca irresistible.
"Like this?"
"Don’t cover your face—I want to lick those eyes."
"You’re okay with it covering down there, though?"
Even her most intimate areas were completely enveloped by the dark energy, inside and out.
What kind of perfection is this? Choi Si-woo, you little minx, you’re really pushing all my buttons now.
"Haah... haah. My body’s just built this way."
"And yet your erogenous zones are still intact? I like that a lot."
I slid my fingers deep inside her, my tongue eagerly wrapping around her clitoris, rolling it within my mouth.
Her clit was just the right size. Considering it had transford along with her, I half-expected it to be larger, but it was manageable, fitting snugly in my mouth and providing a satisfying sensation as I teased it with my tongue.
"Haah… Haaahng… Haang… Hmmng."
"White fluids, huh? I half-expected even that to be black. That would’ve been sothing."
Honestly, I was a little curious. After all, I’m not exactly picky when it cos to taste.
"As if! Though, if I tried hard enough… Hiiiih?!"
Splurt! Splurt!
Her fluids sprayed all over my face, completely soaking in this lewd woman’s essence.
"I’m your queen, and yet you think it’s okay to squirt all over my face like that? Such a lewd little thing, aren’t you? Looks like I’ll have to punish you with so proper grinding."
Spreading Choi Si-woo’s legs wide, I matched her position, opening mine as well until our bodies pressed together. I reached for the dildo I had used earlier—before she fully succumbed to Lust. Without hesitation, I pressed it against my own wetness, then aligned it with her dripping entrance, slowly sliding it inside both of us while rubbing our clits together.
"Hikkuht!?"
"My dildo, crafted from my scales, is sothing else, isn’t it? With dark energy spilling out like that, it’s practically an aphrodisiac for monsters like you."
Squish, squish.
With the dildo inserted between us, we continued grinding our clits together, pressing deeply into the most sensitive spots inside each other. The obscene wet sounds of our mingling fluids echoed as we moved, sticky and lewd, amplifying the heat between us.
Shifting closer, I pressed our chests together, rubbing our nipples against one another. It was an advanced position, a perfect ld of our bodies—our two sexes and breasts fully intertwined.
This was a unique position only I could pull off.
"Haah… Haaahng… Hnnngh… I-I'm about to cum—! Ngh, mmmph!"
Without holding back, I kissed her passionately, our tongues intertwining in a deeply sensual embrace. The kiss grew hotter, more intense, fueled by Choi Si-woo's overwhelming arousal. Her body trembled under mine, her hips shaking as the waves of pleasure coursed through her.
Splurt! Splurt!
As Si-woo climaxed, her release triggered mine as well, and we reached our peaks together.
"Haaaah… Haaahng… Haaah♥"
"Hnnngh… Hngh… Hhhngh♥"
With our bodies still pressed together, soaked in each other's fluids, Si-woo and I clung to each other for a while, finishing our mont with a lingering kiss. We stayed close, savoring the afterglow.
"You really let a lot out, huh?"
As I looked at her, a third eye appeared on Si-woo’s forehead.
Was it sothing triggered by the peak of pleasure? Or was it so kind of other ability? Whatever it was, my insatiable dragon instincts found even that unbearably arousing, my core trembling with excitent. I had planned to take Seo Ji-yeon first, but this was far more satisfying than I had expected.
"So, what are you going to do now? Lust can’t grow stronger without sex, right?"
"My power works a little differently."
"How so?"
Could it be that her Lust wasn’t the usual kind?
"I can create monsters under my control. And when those monsters have sex, their actions feed into my strength."
"Is that an additional ability because you’re the original Divine Sword wielder?"
"Seems like it."
The abilities of the Sins—no, perhaps her power arose to counteract the threat of being NTR’d, as if it was ant to shield her position.
"How adorable. You were born for the sole purpose of eting and grinding against . But really, are you okay with this? You’re supposed to protect not just the world, but humanity too. How does it feel, turning them into your subordinates?"
"The thought that I, who once wielded the Divine Sword to protect people, now corrupt them… It’s so thrilling I can hardly stand it♥."
The protagonist of the original story had now fully embraced her corruption, reveling in the act of leading others into depravity.
Why is it so satisfying to watch soone fall, especially Choi Si-woo? The idea that I managed to corrupt the protagonist makes sothing deep inside stir with excitent.
"I like the sound of that. So, where are you going to recruit people from?"
"The Academy, of course. I’m going to turn all the female students into monsters."
Ah, there it is again—another rush of arousal.
"Should we grind a little more?"
"Okay♥."
We ended up grinding against each other several more tis after that.
Choi Si-woo, now fully embodying Lust, could afford to feel a little proud of herself. After all, she had climaxed seven tis in total. On top of that, the lingering sensation of her orgasms left her womb trembling for quite so ti.
"So, should Choi Si-woo handle things during the day, and you take over at night?"
"If that’s what you want, I’ll do it."
Hearing her willingness to follow my words, I leaned in and kissed her lips.
Truthfully, if the Celestial’s personality could rge entirely with Si-woo, that would be the ideal outco. But for now, the Celestial’s will still dominated—it was stronger by nature.
At the very least, their power levels needed to be on par for integration to be possible. While Lust and the remnants of male Si-woo might be battling internally, the Celestial existed as a completely separate entity.
One thing was clear: Choi Si-woo needed to grow stronger.
As for …
"Kkyuit."
"Wait, why are you here? This place is far from Songdo."
I guess it’s ti to prepare for so snake stew.
