Chapter 1
"It's an injection, a dick injection♡ What the hell happened?"
I was definitely clearing the gate all by myself. It was a high-level gate, pretty dangerous stuff, but my arrogance got the better of me, and I went in solo. I made it right up to the final boss monster, the dragon, on the verge of killing it. The moment I was about to unleash my frost at the dragon, teetering on the edge of death...
'Mana...'
My mana had run dry. Whoosh───!
The last thing I saw was a blinding white breath filling my vision...
"...Ah."
I died, didn't I?
When I came to and opened my eyes, a pristine white hospital room greeted me.
'Not the afterlife... I think?'
Blink. Blink.
I blankly blinked my eyes, then reached up in shock to touch my face. Smooth skin met my fingers.
"Am I... alive...?"
I was sure I'd died, but here I was, perfectly fine. It was unbelievable.
'I can feel my mana, too...'
If anything, it felt even fresher than before. As I scanned the room in this bizarre haze, I froze at the sight of my body.
Or rather, I stopped without realizing it.
"...A woman?"
This wasn't the body I was used to seeing. There was a new curve right below, and my arms were slender, fragile enough to snap at a touch. No way this was a man's upper body.
Confirming that, I realized my voice—and the soft touch on my face—didn't feel like mine either.
'What the hell is going on...?'
Whoosh.
Unable to process it, I shoved the blanket aside and got out of bed, heading straight for the mirror nearby.
"...Ah?"
My eyes met those of a stunning woman I'd never seen before. Long black hair with a faint blue tint, deep black eyes. Even that alone made her a knockout beauty, but glancing down revealed enormous breasts straining against the hospital gown, cleavage peeking out. My jaw dropped on sight. Exaggeration aside, they were face-sized.
Smooth. Blink. Blink.
As I moved, the woman in the mirror mirrored me perfectly, blinking in sync. Dazed, I placed a hand on those breasts.

"This is... me...?"
A woman with violently huge tits was really me? It was impossible to believe, but every detail screamed it was true. Surviving was a miracle in itself, but in a woman's body? It sounded like bullshit anyone would dismiss, yet here it was, happening to me.
"Haa..."
Still reeling, I crawled back into bed and sighed.
"Why are the boobs so damn big... Ha, what do I do now...?"
The A-rank hunter I was? Gone. Now there was just this pitiful woman with a yin body. What was I supposed to do in a form like this?
'...Whatever. I'll just become a hunter again.'
In the end, hunting was all I knew. With the ambient mana feeling even richer than before, growth might come even easier.
'More importantly, how much time has passed?'
As I glanced around for a clock, someone arrived at the door.
Knock knock.
A pretty nurse slipped into the room.
"May I come in...? Oh? You're awake, miss! Feeling okay~?"
Her voice was soft and sweet, paired with a radiant smile that could soothe any soul. No goddess could compare.
'Whoa, she's gorgeous...'
Cherry blossom pink hair, blue eyes brimming with affection. Her nurse uniform was so short it threatened to reveal her panties. Was that slight bulge below just my imagination? Staring alone felt like falling under her spell.
'Come to think of it, do I call her "sis" now...?'
I'll figure that out later.
"You're Han Seoyun, right?"
"Ah... Yeah..."
I answered awkwardly, still gawking at her.
'...Han Seoyun.'
My old name, just the last syllable swapped. That was me from now on.
"They found you collapsed on the street. The area was frozen solid, so it looks like you passed out from awakening aftershocks."
"Yeah, yeah."
She explained more, but I just nodded mechanically. Honestly, nothing registered. I'd barely talked to women before, let alone one this stunning.
"Good news is the tests show no issues, but you should rest up~"
"..."
I nodded again, and she knelt one knee on the bed, leaning her upper body toward me.
"Miss?"
"...!"
She reached out, wrapping an arm around my neck and whispering in my ear. I flinched hard. Our soft breasts rubbed together at such close range, sending a weird tingle through me.
"You okay?"
"Y-Yeah... Haha... Must be from just waking up..."
She was way too close. Where was I supposed to look?
'Isn't this too close...?'
Even thinking of her as another woman, the skinship felt too intimate. Panicking in place, she placed her other hand on my forehead.
"Your face is so red, but no fever? Nothing wrong with your body?"
"N-No! I'm fine!"
Nothing was wrong. It shouldn't be. It was just...
"Hmm, miss, your shoulders must be stiff from lying around so long, right?"
"N-No, they're fine."
It was all her teasing behavior making me blush. She was just worried, but why was I embarrassed?
Smooth.
Her hand slid from my forehead, wrapping around me.
"Or instead of a shoulder massage, I could do somewhere else. Like..."
Her hand trailed down from my shoulder, slipping toward my hospital gown. The moment it aimed for my breast so casually...
I shoved her away and bolted upright.
"W-Wait! I gotta use the bathroom real quick!"
Any longer, and who knows what she'd do. I couldn't just sit there.
"Take your time~"
She just waved with a smile.
I fled the room, catching my breath outside. 'Wh-Wh-What almost happened...?' Did the nurse go nuts for a second? No way you'd grope a patient like that.
Glancing around, something felt off.
'No men... anywhere?'
Wondering if it was just this floor, I wandered more. Not a single guy in sight. Like they didn't exist.
Maybe my death and this were all a dream. But no, I was definitely alive. Reality, not a dream.
'Some memories are coming back...'
Faint recollections of this body surfaced, but something key was missing. I couldn't recall.
"Hmm..."
What was the point of pondering? I'd just search on my phone.
Creak.
Returning empty-handed, the nurse was still waiting.
"Oh, back already?"
"Yeah..."
A bit rattled, but her bright smile strangely soothed me. Still, with no pain, I couldn't stay forever.
"Nurse, I want to discharge. What's the procedure?"
"Didn't we agree on a massage?"
"Huh? I don't remember saying..."
"Heehee, just kidding."
"..."
Felt pretty serious. If I'd played along, she'd have gone straight for the weird massage.
As I fidgeted, she grabbed both my hands and led me to the bed. Her skin was softer than expected.
"Then before you go, one last injection."
"I'm good..."
"Come on, one shot and you'll taste heaven for real~?"
Heaven from an injection? Total nonsense, but her coaxing was too tempting to refuse.
"...Okay."
"Then pants off, please~?"
"Ah... Sure."
Right, injections go in the butt. Resigned, I started sliding my pants down to lie prone.
But then, a rustle of clothing from beside me. Curious, I turned my head.
'She said injection, so...'
Not prep sounds. I peeked—and froze at the sight of the nurse stripping off her panties.
"Wh-Why are you undressing... Eh?"
Was I seeing things?
'Wh-What the hell, a woman with that...?'
Words failed in my panic.
'Am I hallucinating...?'
A dick where no woman should have one. Blinking didn't make it vanish; that massive thing bulged under her uniform.
Long and thick enough to need two hands. A cock, plain as day.
"Oh, first time seeing a dick?"
She approached the bed casually, like it was nothing. I wanted to back away, but the wall blocked me.
"Wh-Why do you have th-that...?"
My mind was a whirlwind. Why did a woman have a cock?
'That slight bulge... it was the dick?'
Women aren't supposed to have those!
She just smiled leisurely at my stare.
"Why? 'Cause I'm a futanari, duh."
Futanari. If I remembered right, women with both sets of genitals. But real people like that...?
'...She's one. No way.'
Wasn't this the same world? Another one? That explained the richer mana?
Pieces fell into place.
"You said... injection..."
I tried to escape the situation.
"Yup. It's an injection. A dick injection♡"
"Ah..."
Her matter-of-fact tone shattered me.
'Why is it so freaking huge...!'
Even soft, it was intimidating. Now swelling, thickening, standing rigid.
"Ah, looking at you is making me hard♡"
Her slow, predatory movements drained my strength. I knew I should run, resist—but instinct waited for her next move. A tremble started from my fingertips, spreading.
Smooth.
"It might hurt a bit since it's my first time too, but..."
She gazed at me adoringly, licking her lips. Hands planted by my head, she loomed lethally. If not for that cock dominating my vision, I'd have melted.

"I'll make you feel good♡"
"Hic."
But to me, she looked like a predator about to devour me whole.
