Personality Theft Parasite (19)
I had sex with Yustia day and night.
One of the perks of this world was that, unlike reality, you wouldn't get tired no matter how many hours you shook your hips—as long as your stamina stat was high enough, of course.
"Hehe♥ My pussy... it's creampied full of Darling's cum...♥ I'm definitely getting pregnant from this...♥"
Yustia murmured with an ecstatic smile.
"You're already pregnant."
"This one's fake. You know that now. It's not a real baby."
"Then why keep it?"
"Well... because... it was thanks to these kids that you and I could be together. And more than that... my body belongs to you, Darling... I can't just remove them without permission, right?"
Yustia glanced at me, seeking approval.
She was catlike sometimes, but moments like this made her the perfect obedient puppy.
"You're making that horny face again. You're the reason I'm hard."
I slid into Yustia's pussy.
Caught off guard by my sudden thrust, she widened her eyes in surprise and started moaning wildly.
"Ah♥ I just came♥ My pussy's so sensitive right now♥ Without warning♥ Too much♥"
"Not my problem. Just squeeze properly."
"Yesss♥ Darling...♥"
As soon as she spoke, her loose grip tightened fiercely, like it had never slackened.
Even as she rolled her eyes back, stuck out her tongue, lost half her mind, and moaned lewdly, she obeyed perfectly.
I liked her like this.
"Cumming inside?"
"Mmm♥ Fill your cum receptacle♥"
Yustia wrapped her legs around me tight, right where I wanted.
"Haaaaang♥"
I came deep inside her.
Yustia smiled in satisfaction, then cupped my face with both hands.
"I love you... Darling..."
After cumming in her pussy, I fell asleep cradled in her arms.
How long had I slept?
When I opened my eyes, the first thing in my sight was a pair of massive, overflowing breasts. Faint milk stains clung to them from what she'd leaked.
"Sleep well? Darling."
Yustia gently stroked my head as she asked.
"Yeah."
"It's about time to go back. This world's basically done."
Her voice turned serious.
And she was right—my mission here was long finished. This world had reached its bad ending, and Yustia had become part of the app.
Corrupted... or whatever you wanted to call it.
Either way, I couldn't stay here anymore.
"What about you?"
"You know. I'm part of the app now. Just like the other girls you've collected. Succumea's power can't preserve entire creations perfectly, so I'll exist as data fragments."
"You okay with that?"
I was the one who'd wrecked this world.
I knew that, but I still wondered.
Around then, the scenery around us began to crumble.
Unlike my lingering reluctance to leave just yet, it seemed Succumea had no interest in maintaining this pointless world any longer.
"...I've clung to this fleeting world for so long."
Yustia gazed into the distance as she spoke, her voice laced with raw sincerity.
"But only recently did I realize what I truly wanted wasn't the place—it was the person. After losing Mael, I obsessed over this city because traces of the one I couldn't protect lingered here."
Then she turned to me with a wistful smile, infinitely tender and distant.
"Now, at last, I can stay by the side of the one I love... forever."
By then, the collapse had reached our room. The ceiling crumbled, walls fell, furniture shattered one by one.
As everything dissolved into an empty white void, Yustia pressed her lips to my forehead and whispered,
"I'll never lose you again. Never. From now on, I'll protect you."
And then it all vanished into nothingness.
Ching.
The moment I returned to reality, paused time resumed, accompanied by the sharp clang of metal on metal.
I opened my tightly shut eyes to see two swords locked in a struggle of strength.
One from a knight in silver armor.
The other extended from a scantily clad woman in nothing but string lingerie and a collar.
"...What trick is this?"
A bewildered voice echoed from inside the helmet.
I knew it well—Yustia's voice.
"As you can see. I changed my mind."
The relaxed reply came from another Yustia—the peerless beauty with an ominous tattoo on her lower abdomen.
"You're not me. Think I'd fall for some cheap illusion?"
The silver knight parried the sword and stepped back, declaring firmly.
But even I could tell it was a lie. Otherwise, there'd be no hesitation.
"How naive. Lies that obvious just make you pitiful. You already know—your connection to the ark is severed. You have nowhere to return to. You never did. You're just my clone, made by the ark to serve its purposes."
"Shut up!"
The silver knight roared in fury and charged, swinging her blade.
Yustia deflected the brutal strike as if swatting a child's stick and smirked triumphantly.
"Aw, jealous? Makes sense. I have everything you lack—a firm faith, a clear purpose, and even love."
The silver knight was the one crumbling under the pressure.
Their duel looked like two equal swordmasters exchanging blows at a glance, but it was one-sided dominance.
"I'm not as filthy as you...!"
The silver knight raised her sword high, unleashing a radiant slash—the same attack that had one-shot Karl before.
Maybe without the ark's support, it was weaker this time.
"Pathetic."
Yustia extended a hand toward the incoming silver flash, enveloping the front in a dark barrier.
The sword strike vanished harmlessly against the unbreakable shield, not even scratching it.
"What...?!"
Seizing the brief opening, Yustia closed in and thrust her sword straight through the knight's armor, piercing the heart precisely.
"Guh...!"
"No more wandering."
Yustia whispered softly to the silver knight—to herself.
"Farewell, nameless knight."
The silver-armored figure gradually disintegrated into dust, scattering without a trace.
Yustia stared blankly at the sky, then turned to me slumped on the ground. She approached, planted her sword in the earth, and knelt on one knee.
"This sword, this body, this heart—all yours. Your humble servant Yustia vows eternal loyalty as your weapon and retainer. Owner of the app."
"Uh... sure."
I replied awkwardly. The vibe shift made her hard to deal with.
Maybe the resummoning affected her?
But then she grinned slyly.
"What, scared? Darling. You're not as bold here."
Nah, she was fine.
After things settled, Yustia and I headed home.
Ea and the others had been badly hurt protecting me, so I unsummoned them for now. According to Yustia, they'd heal on their own with time—no need to worry.
"So this is Darling's home in your world."
Yustia scanned the living room and nodded.
"Cozy and nice."
Then she slipped off her bikini straps, baring herself completely. She lifted one leg high in a perfect vertical split and feigned innocence.
"Ah~ Wonder if there's a sturdy cock around to pound this horny pussy cool?"
"There's radish in the fridge—use that."
She puffed her cheeks in protest.
"I want dick. Dick. Darling, you're so oblivious."
She demanded it outright, no shame.
Was her personality tweak too extreme?
"Tired. Going to bed."
I'd forgotten after so long in that world— it was the middle of the night here.
"Can I sleep with you?"
"Do what you want."
"Can I cuddle?"
"...Whatever."
She was getting annoying.
"Yay~ Thanks. Love you, Darling."
I peeled her off, washed up in the bathroom, stripped, and hit the bed. She scooted right up, yanked the blanket, and slipped in.
"Night."
I drew the line quick before she asked for more and closed my eyes.
"Night, Darling. Love you♥"
She whispered sweetly in my ear.
How many times had she said it now?
But honestly... it wasn't bad.
