Keep It a Secret from Sis♡
Han Do-yoon was flustered by Lumine Blueheart's actions...
The smoke from the trap he'd set had no effect of inducing sexual arousal. It sharpened instincts with brief thoughts, heightening senses to focus on simple reactions. Against a monster, it would make them scatter at rustling leaves or branches, attacking sounds on impulse. After yesterday's rain, they'd lash out at the muddy ground or swipe futilely at fireflies and mayflies.
So Lumine Blueheart's bold, vulgar behavior could only mean one thing.
'She sees me... as a mating partner...?'
It was shocking that the demure, chaste Lumine had looked at him that way—and as a man, it thrilled him. The proper response would be to give in to that instinct, but the situation didn't allow it. If anything, they were in the thick of war right now. Love might bloom on the battlefield, but their lives were at stake. There was no time to answer her advances.
"W-wait... hold on. This isn't the time."
"Take responsibility♡ You did this to me♡"
Between her legs, her pussy was swollen with excitement, fully ready to take a cock. Her underwear was soaked translucent, love juices gushing out to trickle down her pale thighs.
Han Do-yoon swallowed hard at the sight, nostrils flaring... The crude, lewd scent of a female in heat wafted toward him.
"N-no... What did I even do...? And this isn't the moment anyway."
"Hurry... like yesterday, torment my pussy... Hiiik♡♡♡!"
Lumine gathered her breasts from below, thrusting out her erect nipples. Her upper body smothered his face as she swung her tits left and right in a playful punch... She smelled like she was ready to make babies, a sweet milky scent kids would love.
"Me? I didn't do anything yesterday."
"Huuut♡ You're so mean... Yesterday, you showed me... the joy of being a female!"
To Han Do-yoon, who couldn't remember yesterday's events, this was baffling.
"There must be some misunderstanding... You're poisoned right now. Snap out of it, Lumine!"
Her body stiffened at his emotionally charged shout. She blushed, then slipped off her shoulder straps to bare her creamy breasts.
"Ah... ugh..."
He blanked out for a second, letting out a groan. He tried to look away, but his eyes stuck to her pink areolas.
'Don't look... Estelle had her reasons for the eyepatch, but Lumine has nothing to do with it... Sluuuurp.'
Drool dribbled from his mouth. Sensing he'd half-fallen already, Lumine tossed her glove at his face like a knight challenging a duel—then provocatively stripped off her drenched panties.
"I might ovulate today♡"
"D-don't..."
"Don't you want to taste my most female part♡ I know how males look at me."
"W-we're in the middle of a trial, mid-battle!"
"This is my battle♡"
Lumine stubbornly grabbed his hand. He couldn't resist her touch. Before he knew it, his palm rested on her soft breast. He felt her heart pounding wildly.
"Haaah♡ Uh, uhuut♡"
He'd barely touched her, but she bucked her hips, squirting like a blue dragon even into empty air.
Han Do-yoon twitched his fingers, fighting the urge to grope roughly like a claw machine. He wanted to chew those stiff nipples, mark her pale skin with his teeth.
"D-don't... I have K-Karia. I can't take responsibility for you."
"Sis...? Don't worry... That idiot doesn't know we're doing this."
"Isn't that too harsh on your sister?"
"...Sis is the harsh one. Keeping something this good all to herself...♡"
Lumine's gaze dropped below his navel... His erection strained visibly against his pants from her relentless teasing. Feeling her eyes, he tried to back away—but sandbags blocked him solidly.
"What... are you looking at?"
"You know♡"
A smile full of novel mischief curved her lips. Her tail flicked, nudging his belt buckle. He startled and blocked it; her other hand seized both his arms.
"Stay still♡"
"We can't. You and I... thinking of your sister and me, this is wrong. No blood ties, but we're practically family..."
"Who cares about family trees in a world like this? And..."
—Shluck!
His pants yanked down, revealing his throbbing red cock, eager for what came next.
"...You were gonna shove this in my pussy first!"
It sprang up, slapping her lower belly as she reared back. Straddling it like a pillar, hot sticky fluids poured like leaking engine oil, drenching his shaft.
'This is... bad.'
His pent-up urges threatened to explode. Sensing his wolfish glare, Lumine bit her lip. Her eyes gleamed with feral lust.
'F-finally!'
Han Do-yoon shook off her grip, seized her shoulders, and slammed her forward onto the sandbags.
'Eh...? F-from behind?'
The mating Lumine knew was like wild dogs. She had no clue about human sex. Instinctively, she lifted her heels and ass—the female posture to accept seed, keeping it from spilling, drawing it to her womb. Her expectant pussy clenched and squirted.
But even in lust, Han Do-yoon stayed clear-headed.
'Not now.'
He didn't know her dream from last night or her hidden feelings, but this wasn't the time to ram his engorged cock into her gaping pussy and pump it full of thick cum. Nearly sky-blue pubic hair. He parted her soaked folds with his palm and shluck! plunged his middle finger to the hilt.
"Hii, hiiiiiik♡♡♡!"
A place untouched by man; he felt her thin hymen. Half-dragons' hymens broke and reformed during egg-laying cycles—until they took a mate. Once claimed, it never healed. Meaning... Lumine was a virgin.
Plenty loose from arousal, he stretched the small hymen opening, probing the bumpy ridges... Finding the dense pleasure spot was easy. Her reaction exploded the instant he touched it—from panting like a dog to thrashing wildly.

"Huuet, et, hu, heeeeeek♡!"
Her hips shook to escape pleasure. Yet her labia smack, smuuuck, sucking his finger lovingly like candy. Her walls clenched in protest, but her ass pressed closer.
"Cover your ears for a sec."
Gripping Last Wish in his left, he kept finger-fucking her pussy with his right and pulled the trigger.
Bang! Baaang! Bang!
Naturally, it turned into him pinning her from behind—but each recoil jolted her ass hard.
"Heuk! Heuk!"
—Spluuurt...
True to a blue dragon, she squirted impressively.
"Karia, as a red dragon, evaporated the moisture with heat... but you're the opposite, huh?"
Too lost in ecstasy to reply. Han Do-yoon finished off the approaching monsters and turned to her. He'd heard splashing; a puddle had formed under her legs. He withdrew from her G-spot. His fingers were red and swollen like post-sauna.
—Sniff. He inhaled and tasted. He knew pussy wasn't always great in taste or smell, but it was addictive.
'Even after trying so many... nothing hooks you like this.'
Immediate threats cleared. The mana scope before Floor 20 had paid off. Mid-range shooting made buying time possible.
'Might as well satisfy her quick while I can.'
Kneeling low, his view filled with her glistening lower half. Kneading her doughy thighs, her hole smack, smack, begged for love.
'Gotta keep her dazed for a bit.'
"Huuuh...?"
Lumine lifted her head when he pulled away, confused. But then something hot and squishy teased her crotch—she arched rigid again.
—Lick!
"Wha, wha... hiiiiiik!"
Her calves tensed, glutes forming a perfect apple ass. Han Do-yoon buried his face in her exposed pussy like biting a halved apple.
"Why, why eat th-there... Ahk, huuk, haaaahut!"
His nose pressed her pale anus. Tongue sliced her sealed outer lips, pierced the faucet-like inner ones, prodding where molten honey flowed.
He gripped her writhing ass, yanking it wide to expose every crevice.
'Ahk... why there... S-sissss!'
Lumine resented Karia fiercely. Keeping this bliss to herself... Before experiencing it, she'd mocked Karia Redheart. A proud dragon-blood, pinnacle of life, raped by a pathetic rain-soaked human? Exposing her sacred egg-laying spot, writhing in spawn display, toyed like a child's plaything?
'If I'd known it felt like thiiiis... I should've shared hiiiim♡♡♡!!!'
Now she got it—why Karia grinned after rape, stayed by this man, strutted like a horny hen leaking pheromones.
'Nooooo♡ I'm turning human toooo...♡'
"Heuk! Heukgruut! Huuuuuung♡♡♡!"
Finally peeling his tongue from her octopus-suction labia, Han Do-yoon stood and laid his cock between her ass cheeks.
Straddling the shaft in her crack.
'W-wait... n-now? Now? It's time? M-me too...♡'
He wielded his dick like a rolling pin. A poke at her pussy, and fluids squirted like a punctured balloon. He smeared the overflow along his length, grinding crotch to crotch.
Tension, excitement, anticipation—every hole on her body winked open. Hng, huuut, hurry, pleeease...
But his next move dashed her hopes.
"Damn... more monsters incoming!"
He pinned her down in a rush, aiming.
—Bang!
Each shot and recoil tortured Lumine underneath. Her hole teased penetration but never quite.
"Eh... heuk, p-please... s-stop...♡"
—Bang! Bang! Bang! Bang!
"Sorry! Just a bit longer!"
—Bang! Baaang! Baaaang!
Her nipples scraped sandbags, glans grazed and retreated from her pussy. That alone webbed their groins with sticky threads, like they'd mated.
—Schlick, schlick, splurt, schluuuurp!
"N-no more... I c-can't hold... baaack♡♡♡"
"Sorry, didn't hear. What?"
Lumine shoved him off and bolted up. She mounted him at last.
"Sorry... borrowing it a sec... Keep it secret from sis♡"
Dragons knew squats well. In spawn-ready pose, she stole her sister's cock into her egg-laying hole.
—Shluuuuck!
"Hngruuuut♡"
Hot fluids milked him like a vice.
