Heroine Hunts Heroines

Something within me had been changing for quite some time—I had known that much.
I had thought about wanting to become a woman. But it was just a fleeting wish, something I never imagined would actually come true.
After becoming a woman, many things changed. Men no longer looked at me 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. Women, on the other hand, stared at me with eyes filled with envy.

Before I realized it, I had started to gain confidence in my appearance. I dismissed the men with a contemptuous sneer, as if to say, You dare think you’re worthy of me? And I mocked the women’s jealous stares, taking pleasure in their resentment.
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 me, took root and gave birth to an entirely new persona.

That persona was a version of me 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 dimmed 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 extreme sexual pleasure or use its full powers, leaving it comparatively weak. Lust seemed 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 came 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 moment, 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 pummeling, I somehow managed to regain my senses.
But Eun-ha’s intentions went beyond simply putting Lust in its place.
Eun-ha had a plan—to merge me with Lust, fully integrating the two of us into one. She intended to turn me into the very embodiment 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 me. 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 me that… felt it.

Every time she struck my lower abdomen, a strange, maddening sensation spread inside me, making me 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 something lower, something degraded—an existence completely consumed 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 me, shuddering with joy even as the blows rained down on me.
But there was something missing.

The satisfaction wasn’t complete. I felt blocked, as though something deep within me refused to let go. This resistance—this recoil—came 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 me 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 time 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, something inside me screamed, urging me to listen to Eun-ha's words, as if my own mind had turned against me.

—Just accept it already.
—You're a woman now, anyway.
—Sure, getting nailed by a cock might sound extreme, but if it's Eun-ha, I don't mind at all♥
—I’m you, too. Stop tormenting 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 me, begging me to give in.
My resolve was weakening. With every moment, I could feel my womb—a part of me I couldn’t deny any longer—proving my femininity. Every time Eun-ha’s touch made me tremble with sensation, it became 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 women 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 come 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 become a bitch who follows someone more reliable. A slave to them. Be honest—you’re already a bitch. Don’t feel ashamed of having been a man before. Just embrace it. There are plenty of women like you, so it’s not strange at all.”
Each time I heard Eun-ha’s voice, my lower abdomen quivered uncontrollably.
My womb throbbed, betraying me with its every beat. A woman’s body was meant to be molded to fit a man’s, yet here I was, being reshaped to fit Eun-ha instead.

Even something as intimate as scissoring sent waves of overwhelming pleasure through me.
"Hnn—!"
“What’s this? Why are you trembling all of a sudden?” Eun-ha teased, her voice dripping with amusement.

"I-Is this really okay?"
The words slipped from my lips, unbidden.
"Exactly. Now you’re going to become a proper bitch, someone who follows someone more dependable. A slave, obedient and true. Be honest—you’re already a bitch. Don’t feel ashamed of once being a man. Embrace it. There’s nothing strange about it; there are plenty of women like you."

With every word Eun-ha spoke, my lower abdomen trembled uncontrollably.
My womb pulsed, beating with a rhythm I couldn’t deny. A woman’s body, designed to complement a man’s, was now remolded by Eun-ha, reshaped for her alone. Even the intimate sensation of scissoring—something 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 abdomen was impossibly good. My legs quivered, struggling to hold me upright as waves of trembling pleasure surged through me. Slowly, ever so slowly, I felt the build of something 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 time to relax and become 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 me 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 me, Eun-ha wasn’t just a woman. She was the strong, dominant male who had conquered the woman that Choi Si-woo had become, body and soul.
I couldn’t resist anymore.

Eun-ha told me not to be a wielder of the Divine Sword or a hero but to live as her woman, to become 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 moment, Lust, which had been waiting inside me, began to entwine itself with me 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 emerged. A woman. A vessel for Lust, finally accepted and complete.
In that moment, the pleasure I had held back for so long crashed into me like a tidal wave, pulling me into its depths.

Letting go of reason, the world looked entirely different.
Thump-thump. Thump-thump.
Dark, immense energy surged out from within me, 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 me, making my womb tremble.

“Haa… Haa… Haa…”
Pleasure I could have never felt as a man. Not even during those private moments of self-discovery. No, this was on an entirely different level, beyond anything I’d experienced before.
Was this what it felt like to become a monster? Or perhaps it was because I had accepted Lust completely. I could feel my human heart being replaced by something 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 me turning white as my perception shifted entirely.
With a sudden, explosive sensation in my lower abdomen, something 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 men. 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. Some even consume humans they love, desperate to fill that void.

Now that I had become Lust, I understood.
This boiling, overwhelming power surged within me, and alongside it, the certainty of my submission to Eun-ha.
The transformed me knew one truth: Eun-ha wasn’t just my master—she was someone 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 something 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 menacingly 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 some time, the dark energy, now resembling latex, was completely absorbed into Si-woo’s body, and her face returned to its original form.
It seemed 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 enhancement. 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 emerge.
Her violet eyes, now gleaming with a seductive heart-shaped shimmer, 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 merged with Lust. Whatever remnants of her former male identity had been completely consumed, 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 excitement, 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 me."
Her face, twisted with lust like someone consumed 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 claimed 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 come. 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 become nothing more than a depraved woman consumed by desire.
Well, it was Lust, after all. This outcome 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 me, that’s all that matters♥"

Who would ever believe this was the same Choi Si-woo?
"You cheeky little thing. Cover your body with that dark energy."
Suddenly, the thought of latex play from earlier became 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 transformed 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 something."
Honestly, I was a little curious. After all, I’m not exactly picky when it comes to taste.

"As if! Though, if I tried hard enough… Hiiiih?!"
Splurt! Splurt!
Her fluids sprayed all over my face, completely soaking me 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 some 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 something 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 meld 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 moment 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 something triggered by the peak of pleasure? Or was it some kind of other ability? Whatever it was, my insatiable dragon instincts found even that unbearably arousing, my core trembling with excitement. 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 meant to shield her position.

"How adorable. You were born for the sole purpose of meeting me and grinding against me. 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 someone fall, especially Choi Si-woo? The idea that I managed to corrupt the protagonist makes something deep inside me stir with excitement.
"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 times after that.
Choi Si-woo, now fully embodying Lust, could afford to feel a little proud of herself. After all, she had climaxed seven times in total. On top of that, the lingering sensation of her orgasms left her womb trembling for quite some time.

"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 merge entirely with Si-woo, that would be the ideal outcome. 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 me…

"Kkyuit."
"Wait, why are you here? This place is far from Songdo."
I guess it’s time to prepare for some snake stew.
