16. Shall We Go Outside Like This?
Seong Yuna crept closer, as if she knew exactly what state I was in, grinning wickedly down at me.
"Seoyun unnie, you in heat?"
"Eh…? N-no, that's…."
I wanted to deny it, but then Yuna's hand gently pressed and stroked my lower belly.
Kkuuk♡
"Haht?♡ Eut, w-what are you…."
The pressure on my womb drew an involuntary moan from my lips. Just that touch on my heated lower belly sent stimulation straight to my core, pleasure slowly spreading through my entire body.
"Mm… ready for sex?"
Through my hazy mind, I caught Yuna's mischievous smile as she watched me.
…Ready for sex?
"…Huh?"
"Your body got all hot the moment we entered the gate today, right?"
"How did you…."
"Actually, that was my doing."
"…What?"
So, this burning heat in my body right now… it was because of the smoke Yuna made inside the C-grade gate?
"Yeah. I heard women need to be in heat for sex, so I wanted to experiment."
"Then why test it on me…."
I mean, she could've just experimented on her own….
"Because Seoyun unnie keeps turning me on?"
"I didn't do anything…?"
All I'd done was answer Yuna's questions. I'd never flashed my breasts or tempted her with my ass or pussy. Really, I hadn't.
Yuna's response was brutally simple.
"Just looking at you makes my dick hard. It's a first for me, so I wanna fuck unnie."
As if my opinion didn't matter at all, Yuna climbed onto the sofa. My body was already aroused, and seeing her excited expression like mine made my resolve waver.
No… how many times is this now….
"Unnie, you're super pretty, you know?"
"…."
Was that all women were in this world? Just holes for futanari cocks?
I trusted her….
Yuna had seemed like such a pure little sister; I'd let my guard down.
Am I getting fucked again…?
No one had told me to trust anyone, but betrayal stung in my heart anyway.
Sararak, ssureuk.
Meanwhile, Yuna steadily stripped off her clothes one by one, as if savoring my gaze. With each piece of fabric falling away from her skin, her perfectly proportioned, beautiful figure emerged. Finally, her pants and underwear dropped together, her massive cock flopping out heavily.
Thud.
The thick shaft, dripping a bit of precum, was laid across my belly.
"You don't like me, unnie?"
Sararak.
Yuna naturally started undressing me as she asked.
"N-no… that's not it…."
"This is my first time too, so that hurts my feelings."
She put on a slightly sad expression as she said it. It was so convincing I felt guilty for no reason.
"Um…."
"…So you like me?"
"Y-yeah… I do…."
She seemed like such a sweet, innocent little sister; I'd just been caught off guard by the suddenness.
Did genius mages ever act without reason?
"Then it's okay if I do it?"
"Ah…."
I fell for it immediately. The shift from sad to bright wasn't her first time pulling that trick.
…This girl's not so innocent after all.
The thought that Yuna might be a bit sly lasted only a moment. This wasn't the time.
I was in danger of getting eaten.
"Then I'll take that as permission…."
I stayed still, and Yuna pulled back, flipping onto her stomach and shoving her head between my legs. I felt her hot breath, her gaze piercing my pussy, but even pushing with all my strength did nothing. Before I knew it, her lips kissed my dripping slit.
Chup…♡ Chu-reup…♡
"Haaak…?!♡ Haht…!♡"
Her tongue lapped at my clenched folds with a wet chu-reup, making my body twitch. The soft pressure of her tongue felt so good, and when the tip teasingly flicked my clit—
Pfush…♡
"…♡"
Love juices squirted from me in bursts. Yuna pressed her lips to my pussy, drinking it all down. It must've been sweaty, must've smelled weird, but she didn't care, tormenting me while enjoying my reactions.
"This tastes better than I thought?"
"D-don't say that…♡"
The lewd sounds from my pussy and her teasing words only heated me up more. Yuna moved her free hands to push me over the edge. One pressed firmly on my lower belly—kkuuk, kkuuk♡—stimulating my womb, while the other plunged straight into my pussy. Her index and middle fingers gently scraped the entrance before slipping softly into the tight seam of my mound.
At the same time, her tongue slid up from my slick inner walls to tap my clit, and the fingers inside teased my G-spot relentlessly.
Chu-reup…♡ Chup…♡ Jji-geureok…♡ Jji-geureok…♡
She rubbed and licked my swollen, burning clit with her lips, pressed my womb while kneading my G-spot. Her relentless assault on my weak spots left my mind in a fog.
Pfushuuut…♡ Pfushuuut…♡
"Hewik…?!♡ Haht, eut…♡ S-stop, that…♡ I-I'm getting weird…♡"
"It's fine. We gotta cum at least five times before sex, right?"
Where'd she learn that…♡
"……♡"
With my womb and pussy under total siege, my brain went dumb and blank. Yuna showed no sign of stopping between my legs—clearly aiming to knock me out with orgasms. My body floated weightlessly, every inch hypersensitive and tingling. I barely noticed her hand leave my lower belly as she groped near my womb. Just her tongue on my G-spot and clit had me shuddering into climax after climax.

Pfushuuut…♡ Pfushuuut…♡
"Heeuk…♡ Heuk…♡"
Only after wringing every last drop of juice from me did Yuna finally rise, the hot presence between my thighs vanishing. I had no idea how many times I'd cum. My mind was hazy, my sweat-slicked body hypersensitive, my pussy clenching and twitching nonstop.
I sighed in relief, thinking it was over at last—but then—
Thud.
A scorching-hot cock, oozing precum, slapped down on my lower belly.
"Seoyun unnie, tired already?"
"Haeung…♡ Y-Yuna…♡"
She wiped the juices from her mouth, licked her fingers clean of my fluids, and flashed a seductive smile. Her eyes devoured me, her excitement shaking her body—and mine didn't cool either.
She gripped her unwieldy shaft, slapped it twice, and aligned it with my pussy. The slutty kissing sound of glans against folds told me it was coming.
Tak.
Yuna seized my hips with both hands, ensuring no escape, and stared intently.
"Can I put my dick in?"
"Hau…♡"
Instead of words, I cautiously rocked my hips, rubbing my pussy against her tip—the same things futanari had done to me. Yuna smiled happily.
"Then, I'm putting it in?"
Tzugeureok…♡
I tensed, clenching my lower belly against the massive cock's pressure at my entrance. Her thick glans rubbed my freshly licked folds, probing for the hole, then plunged in, scraping every inch of my tight walls.
Puuk♡
"Hfut!♡"
Slowly, savoring each fold, her cock dragged dizzying pleasure through me. My pussy softly embraced the invading girth. When her tip kissed my womb's entrance—chup♡—the pressure hit hard, and I came without thinking.
Jjibop♡ Jjibop♡ Jjibop♡ Jjibop♡ Pfush…♡
"Eut, it squeezes so tight…? Pussy feels this good…?"
"Haaang…♡ D-dick…♡ Too big…♡"
"You love my dick, so I love it too…♡ Eut, but I'm gonna cum already…."
Yuna tested a gentle thrust, frowned slightly, then slammed fully home.
"Heeuk?!♡"
Her huge cock crushed my womb, my body mistaking it for ecstasy as I came again. Thick semen erupted in heavy spurts.
Byurururung…♡ Byururung…♡ Pfushuuut…♡ Pfushuuut…♡
"Eut, cumming inside feels so good…."
"Haeut…♡"
I came so easily from a single thrust, so I got it—but her climax triggered mine. Even after one load, her cock stayed rock-hard inside me.
"Yuna, that was a quick-draw dick…?"
I wanted to tease a little. It was her first time, so she popped immediately—but give it time, and she'd turn the tables.
"Came the second you put it in…? So cute, Yuna♡"
"…."
As I teased her flushed, embarrassed face, her expression cooled. Her chilly smile made me tense.
"…Kinda pissing me off?"
Yuna lifted my limp body, keeping her cock buried as she turned me into doggy position, steadying me on my feet. Pfush♡ Pfush♡ The stabbing sensations as I spun triggered another orgasm, and suddenly I stood before the door.
"I found something I wanna try while researching sex lately? Can I?"
"W-what…? Ah, no way…?"
Anxiety flashed through my mind as I realized what she meant.
"Shall we go outside like this? Bet it'll be thrilling."
"……!"
Before I could speak—
Kkiiik.
Yuna twisted the doorknob, grinning wickedly.
