Unaware Someone Was Watching Them
Beastlike passion continued unabated, oblivious to the eyes watching them.
'W-was it always this intense?'
Han Do-yoon nearly pissed himself at the sight of Lumine's exquisite, overwhelming power massacring the monsters in a single stroke. Just moments ago, she'd been nothing but an adorable half-dragon he wanted to stuff full of eggs. Now, she terrified him. The fear gnawed at him—the fact that he'd surrendered his body to someone strong enough to grab his throat and snap it like a twig. Their brief connection only amplified the unease of low trust.
It was different from when Isana, Evelyn, or Estelle had raped him. With those three, there was certainty, a deep emotional bond. But Lumine... no. She was a complete stranger, someone he'd known for barely any time. There was no reason for her to beg him desperately or cling to him obsessively. That's why he was scared.
...Yet his cock grew even harder.
"Hngaaaah♡ B-bigger, make it even b-bigger♡ Ah, haaht, hngaaaah♡ N-nooo! My babies are gonna get crushed...♡♡♡"
Even as she said that, her thighs stayed locked like heavy machinery staked to the ground. Han Do-yoon tormented her clit with his free hand. Flicking his thumb over the spot hidden in her blue pubic hair made her hips buck even more erratically.
"D-don't, don't do thaaat♡ Hngaaaah♡ I-I'm gonna cum agaaain♡"
-Squelch, squelch, spurt...
As he teased her clit, her hips jerked wildly amid screams of heuk, heukit, hnguuuuh. The moment her steadfast thighs slackened just a bit, Han Do-yoon seized the recoil and swiftly flipped their positions.
"H-huh?"
Lumine blinked in confusion at the sudden reversal. Before she knew it, Han Do-yoon was on top, plunging his long spear deep and grinding in circles.
"N-noo...♡ Nooo! N-not like thiiiis! Hng, hngaaaah, hrnght♡"
"This is how humans fuck! It's not just about pounding in spawning position!"
"H-how dare...♡ A lowly, inferior...♡ human like you...♡ mounting a dragon... Hng, hngaaht, ughk! Eek, eeeek♡ N-nooo!"
"Acting all mature, but you're a racist, huh?"
"S-sorryyy, I thought humans were pathetic♡ Too weak to be of any use...♡ Heuk, ah, nooo...♡ Now I wanna fuck a human♡ I wanna bear human babies, hngaaaah♡ Thrust deeper♡♡♡"
Like a fly caught in a web, Lumine's wings folded around Han Do-yoon, trapping him. Her tail slithered slickly over his asshole, thighs, and lower belly in a caressing embrace. Her arms wrapped around his shoulders, nails digging into his back as if to never let go. Her pale, chewy thighs pressed their groins even tighter, calves clamping like scorpion pincers to pull him in.
"Hng, hnght, u-uh, heuk, haaht... Love me, love me more...♡"
...The third wave of climax built.
Surge! Throb! Reading the twitching pillar inside her, Lumine flashed her eyes. It was only her second time taking his load, but instinct told her. This male was about to spew sticky seed into her womb again, stamping his claim.
"Hngaaaaah, cum in me♡ Fill me with that gooey stuff♡ Defile my womb with your inferior human cum♡ I'll raise 'em better than sis♡ I'll squeeze ya better toooo♡♡♡!"
-Slam! Slam! Slam!
-Splorch! Splorch! Squelch, squelch, squiiiish!!!
Their bodies slammed together. Sweat-slick skin clung stickily, refusing to part. Their stiff nipples rubbed faces, pubic hairs tangled into white threads. Her labia gripped the invading glans chewy-tight, sucking greedily as if to devour his balls whole. Han Do-yoon panted moans into her ear; she bit his back in unbearable pleasure.
-Surge! Spuuuurt! Splurt, spluuurt! Spluuuuurp!
"H-hngaaaah...♡ U-ugh, uuuwuh, hng, hng, hnghehehe...♡"
The fulfillment of her womb stuffed full. Gooey, solid heat filling her lower belly without gaps, defiling her, branding her hot. ...Han Do-yoon kept grinding his cock-tip against her womb even after finishing, as if commanding her to bear children. Savoring it all, Lumine finally passed out in satisfaction.
-Thud. Wings slumped, tail went limp. But her pussy still clenched his cock to the end, holding firm even as she toppled.
Han Do-yoon caught his breath, shook her gently, and barely pulled out.
Drip, slurp-slurp, driiiip, kweeeen! Their love's product erupted from the red hole. The tiny pussy entrance, like a forgotten balloon hole, gaped endlessly—puffing, fish-mouth-like—spewing its contents.
-Splurt, spluuurt.
"Heut♡ Haaht... Hweeee♡ Me too, just like sis... full♡"

He gently cleaned the settled Lumine and dressed her.
'My cum keeps leaking from her pussy...' It flowed endlessly; he nearly raped her sleeping form. He applied ointment to her sore-looking slit and steeled his resolve.
'This was... a mistake.'
Lumine had inhaled the poison gas, out of her mind. She couldn't make rational judgments. He should've stayed sane and made the responsible, manly choice—but he hadn't.
'Pretend it never happened. So she won't feel ashamed.'
As he finished cleanup and resumed hunting approaching monsters, Lumine woke.
"Huh? Wh-when did I get here... when did I fall asleep?"
She acted like she remembered nothing.
'Does she really not remember?'
Maybe poison-induced amnesia.
'Good, better if she doesn't. If she knew she turned into a cumdump on drugs, she might kill herself.'
Han Do-yoon played it off like nothing happened.
"You flew up suddenly and faceplanted in front of me? I told you—if you need to come back, fire a signal flare, I'd open the path."
"Ahh... Thought flying would be fine... Sorry... Nothing happened to you?"
"...One unexpected beast showed up, but no big deal."
"Good... Ugh, head still hurts. Need more rest."
They'd set up base camp near the altar. Lumine blushed and ducked into the tent.
'Uuu...♡'
Of course, she remembered everything.
'Wh-what now...? How do I face sis... uuuu♡'
She'd thought it a dream. Wanted it to be. But upon waking—
The illusion of his cock still stuffed between her legs. Her broken pussy wouldn't close, cold air rushing in, cum leaking with every step. The stinging thigh flesh proved it real.
'N-no...♡ D-did I do something so slutty... uu... S-sis... sorry.'
Spreading her legs in the tent, driiiip—hidden cum trailed down her thighs. Her white skin flushed red like it'd been spanked, labia majora marked with ointment traces...
'He... applied medicine while I slept? Eh, eheheht♡ N-no, can't think like that.'
Like her mid-sex confession, maybe he'd cum once more while she slept? Imagining that, Lumine tried soothing her twitching labia.
Returning from female to woman would take serious work.
'Th-this never happened. J-just... a midsummer night's mistake. Impossible. Even drugged, I can't steal sis's mate.'
...But could she really not steal him?
She shook her head furiously, scolding her lust-driven self to regain reason. But every time...
She craved it. The feel of it bursting from her panties like a gift box, slapping her belly. The gooey liquid splattering her womb. The love whispers in her ear.
Cold sweat mixed with endless leaks from between her legs. Finally, Lumine bit her skirt hem.
'Ah, ah... no, uung... hnguk... hnguuuk♡ N-no... can't...♡ Ugh, uu, uhrnguuuup! Uup! Puh!'
Before she knew it, her body crouched cat-in-heat style, ass high.

Time passed; party members trickled back one by one. Offering the souls collected in lamps to the altar tipped the scales level at last.
The altar's secret door opens.
-Rumble! A massive quake revealed hidden stairs beneath the altar.
Enter, and the floor boss appears—combat begins... He wanted to dive right in, but one issue.
"...Something happen to Karia?"
"Seen Karia? Why hasn't she come back...?"
By Han Do-yoon's calculations, Karia's soul lamp would fully tip the scales, unlocking the 20th floor's hidden element as planned. But she wasn't back.
'Why isn't she here?'
Karia Redheart was strong. Sure, she'd faltered recently, but her power was unbroken, potential limitless. She was the woman who'd pierced the atmosphere in pure flight, shattered falling 'stars,' altered satellite orbits. Karia suffering on 20F? Impossible.
...She was dumb enough to get lost, though.
"I'll go look quick. Rest up—you all must be beat from hunting."
"Whew... Was dying out there. The potions you gave made fatigue crash suddenly..."
"They're pulling tomorrow's energy... Be back."
He checked the Last Wish handgun and headed out.
'Karia...'
Finding the fire-element master wasn't hard. He pulled thermal-goggle monocle—equivalent to a heat cam—and scanned.
Cold night; she'd be the hottest spot.
'Found her.'
As expected, quick find. Motionless in one spot. Resting? Stuck? Unclear.
He approached cautiously, scoping surroundings. Monsters could pop anywhere.
'What the hell is she doing?'
Mana scope pierced brush; finally, she came into view. Leaning on a tree, ass thrust out, half-red-dragon masturbating atop herself. Opposite her sister's—red fur, pink shell-like pussy. Unconsciously, Han Do-yoon centered the crosshair on it.
'What... right here, now?'

Ridiculous, but he wasn't one to judge.
"Hng, hnguup... Uup, why, why... just me, m-me too...♡"
-Chomp-chomp-chomp-chomp!
Karia ravaged her precious parts with noisy violence. Not his first time seeing her masturbate. Second.
'Again...'
Head dyed black or not, ugly or whatever—no one could resist a flushed, panting bitch like Karia. He'd feigned nonchalance, mocked her masturbation addiction, bullied her... But honestly, since first sight, he'd wanted to tie her like a milk cow, drown that red pussy in white cum like last time.
But he held back. For her sake. She needed sanity.
'Now...'
Thankfully, her head was still red. Not broken yet.
'Not worrying level... so maybe okay?'
Just hours ago, he'd fucked her little sister. Still, his groin stiffened.
...Honestly, guilt made him want to ravage her too. Unintentionally shared love with her sister.
'Almost forgot—I regressed... for you.'
Han Do-yoon unbuckled his belt, approaching.
"Y-you... K-krgh, stay back... That stinky thing... get looost... Hng, hnghnguung♡!"
Karia sensed the approaching mate, wary. But her plunging fingers didn't stop. Scornful face, hips shaking ass like a vase.
"G-get looost♡ C-can't you see... I-I'm, b-buusy?"
"I'll help."
"Shut up♡ D-don't need thaaat♡ shiiit... Hngaaaah♡!"
'No, I do! Please do me too, use me as cumdump♡♡♡!'
Against her heart, Karia spat harshly.
"Try raping me again... Won't let you off! This time for real♡"
Words aside, pussy juice squirted pssh-pssh from red bush. Her scorching red-dragon heat choked him up close, but Han Do-yoon stripped his top, pressing glans to her slit. She'd spread the hole with index and middle, begging entry.
"D-don't♡ Hate it♡ You go away♡ You hate me now♡ No need to force it outta worry... P-prettier than me...!"
-Sluuuuurp!
Welcoming labia kissed his glans with hot breath. Before thrusting into the red dragon's depths, Han Do-yoon cleared the weird misunderstanding.
"I like you. Gave up a lot to come here for you."
"Eh...?"
Scorching heat intensified. Eyes wide, Karia's ready-for-baby hole waited eons, begging. Han Do-yoon plunged deep what she'd craved and pleaded for so long.
"Hng, hht, hng♡... Hngaaaah♡♡... Heuk, heukgit! Gigiggit♡ Heuk!"
His cock felt like it'd cook in the heat. Han Do-yoon mounted from behind, grabbing her tits with both hands.
"Sorry, Karia... Wanted this with you long ago♡"
"L-lieees♡!"
'Uung♡ Kiss-kiss... more♡ Cum quick♡ Say you love me tooooo♡♡♡!'
Karia felt betrayal turn to joy, happiness—thrusting back her ass.
-Sluuuuuuurp!
