The Red Dragon's Fatal Weakness
The venerable weakness of the Red Dragon was utterly crushed as Narin gripped her throat tightly. The sturdy dragon's neck wouldn't even show a fingerprint, let alone claw marks, yet Narin squeezed with all her might. Blue veins bulged in her grip, and it almost seemed like she could hear the grinding of bones.
"Die. Just die already...!"
"..."
"Hngh, hngaaah!"
Thrusting her cock deep into the Red Dragon's pussy while choking her neck. But the Red Dragon stared at Narin without so much as a twitch, like she was carved from stone. There was no pity, no boredom in her eyes. Perhaps just sympathy, or a simple of course.
Those eyes tormented Narin even more.
"So average."
"Y-You bitch!"
"Ah, boring."
Dragons were exceptional. And being exceptional, they adapted quickly. The first time she'd felt Narin, it had been ecstatic, but now? Just meh. She'd adapted. The Red Dragon's pussy had grown accustomed to Narin's cock.
What does she plan to do?
The Red Dragon focused less on Narin ravaging her and more on the two Dragon Slayers watching from behind. Monsters who could butcher her on a whim if they wanted. Why were they just standing there? Her mind spun in confusion.
Humans get bored so fast, huh.
Thud, thud, thud. She felt something entering her depths, but that was it. No pleasure, no pain. Even if she wanted to feel it, her adapted body wouldn't allow it.
Is perfection lonely by nature?
Boredom brought random thoughts.
...She's about to cum soon.
She felt Narin's cock swelling inside her—precisely, in her pussy. Semen gushed out in torrents, pounding against her tightly sealed cervix. Even though hammering it wouldn't open the womb, Narin stupidly kept begging at the gate like an idiot.
Narin pulled her cock out of the pussy and glared down at the Red Dragon with tear-filled eyes. The Red Dragon couldn't fathom why she was looking like that.
"Why are you staring at me like that?"
"...What?"
"The weak are culled, the strong survive. That's the law of nature. I'm sorry your friend died, but aren't you overreacting?"
She meant it sincerely. To the Red Dragon—and probably to other dragons too—the human before her was furious beyond reason. Just a friend, just family. Mere bonds like that. No reason to bare fangs at an overwhelmingly superior being just because they died.
Why do they think dragons don't kill Dragon Slayers?
Because rampaging for revenge could get you killed too—like Stony, then Windy charging out recklessly.
"You're still alive."
The Dragon Slayers behind showed no sign of moving. So she spat out her true feelings. She calculated that this much wouldn't kill her.
"A reasonable argument, in its own way."
"Well, from a dragon's perspective."
Behind Narin, the two Dragon Slayers whispered.
From the Red Dragon's viewpoint, Narin's rage was incomprehensible. Getting angry at someone stronger? Absurd to a dragon.
Dragons were strong. Incredibly so. That's why they bowed quickly to anyone superior.
Because refusing meant total annihilation.
Foolish dragons who couldn't acknowledge superiors were all slain. Natural selection, essentially.
"Well, that's what separates humans from monsters, I suppose."
Elysia nodded at Serena's words. No matter how strong or revered dragons were, they were still monsters. They could acquire knowledge and wisdom, but never truly understand. The drive to rebel against an enemy, even at the cost of one's life—to kill that foe—they could never grasp it.
"Oh."
"Found the weak spot."
Ignoring the Red Dragon's words, Narin awkwardly shifted her hips. Her cock brushed against the entrance to the Red Dragon's rear pussy, then pulled away.
"Ghk♥"

The Red Dragon's sweet moan—for the first time. Even she seemed flustered, question marks popping above her head as her eyes darted around.
"Feisty ones always have a weak rear pussy."
"Is the Red Dragon the feisty type?"
"Dunno. But dragons are usually cocky."
"Guess that tracks."
Elysia shrugged.
"No idea where the saying started. Just... that's how it is."
"Really."
"Yeah. And it worked, so good enough?"
"Sometimes it backfires big time."
"It's fine. Totally fine."
Elysia chuckled lightly, watching Narin.
"Revenge successful."
"Successful... yeah, it is."
"Hii, hiiiooook♥ N-No, stooopaaah!!"
Narin's cock ravaged the rear pussy. A completely different reaction from the front. The walls writhed like living barriers, squeezing the cock, and the semen it produced battered those walls, granting the Red Dragon pleasure and climax.
After that, it was pure violation. Grabbing horns and tail, slamming deep into her guts. The sealed cervix gaped wide, awaiting semen, while her brain melted into mush, leaking from ears and nose.
Her mind turned to chaos; thoughts fragmented. Choppy, fixated only on pleasure.
"Hngh, hiiik. Hoooook♥"
Slap, slap—the sound of spanking her ass. The tough dragon hide showed no marks, but the impact shook her brain again.
A real-time drop in intelligence. Instinct screamed danger, but escape was impossible.
"Heh, heguuk♥ Gyaaaahk♥ G-Guuk♥"
Moans shortened. As Narin's semen filled her guts and pussy, they dwindled, her voice hoarse. Her body shuddered, awaiting death.
"D-Deaath no♥ R-Revenge kill hate...♥"
Instinct warned: this way, she'd die. Not by Dragon Slayer, not by natural return to earth—but climaxing from rear pussy till death. The most euphoric, brain-melting end. Also the most degrading.
"Hii, hiirooooook♥"
Thud, thud, thud. Thud. Thud. Thud.
"Stop."
"...?"
"She's already dead."
Time passed. Elysia hugged Narin's body and said it. Narin pulled out of the rear pussy and looked at her.

"What a ridiculous sight."
Her body trembled. Post-mortem rigidity? Or not fully dead? Unclear.
"Ah."
With a poof—like black ash rising into the air—the dragon's body crumbled and vanished.
"...Kinda anticlimactic."
"Revenge's like that."
"Still, feels good."
Elysia stroked Narin's head.
"Yeah, that's what matters."
Revenge isn't for the dead—it's for the living. Another choice for those who survive loss. A rest only they can grant themselves.
"Even if it's bittersweet or empty, better than doing nothing. That's why we do it."
Elysia deeply empathized.
"Let's go. Head back."
Narin looked up at Elysia with hollow eyes.
"...Yeah."
No question of where.
In front of the snow woman's hot spring inn, Necoma stood with her comrades at the exit.
"Leaving already?"
"Yeah! Time to go, nyang."
Necoma nodded vigorously at Eli, who came to see them off.
Staying longer would've been super dangerous, nyang.
"Memories fuzzy, but it was fun, nyang!"
What exactly happened in the inn? Foggy. But one thing clear: their injury-riddled bodies were fully healed.
"What! Good's good, right?"
Necoma grinned at her comrades.
"Uuuung?"
"What's up, boss?"
"Ung? Why, whaa...♥ B-Bossaaang♥"
"Huh, something's... off."
Necoma stared at her comrades. Same as always, yet something felt wrong. The knight's belly was hugely swollen. Gained weight? Thick white stuff oozed from between her legs.
The mage's belly was normal. But her cock hung limp like overused, covered in saliva or sweat-like fluids.
And both covered in bite marks, lip prints, handprints everywhere.
Fought or something, nyang?
"Nah! Nothing, nyang. But knight, you gained weight, nyang?"
"Ung? No, I didn't?!"
"Then fine, nyang!"
Eli giggled at Necoma and her bickering comrades.
"Safe travels."
"Yeah! See ya, nyang!"
"Knight, you too."
"Ah... Y-Yes, Mistress!"
The knight blushed facing Eli.

Hard to say, but the knight's gaze at Eli seemed especially sticky. Eyes for a lover? No, more like...
Eh... probably nothing, nyang!!
Yeah. Imagination. Mistress-slave between saintess and knight? Impossible.
