The Female-Fallen Hero's Uterine Orgasm Training
And so, Nina set off as the Demon King's spy.
"Kekeke. Now, while we wait for the prey to take the bait, let's take our sweet time enjoying ourselves."
There's still a chance. That smug bastard is acting all leisurely, but he's still right in the middle of Normal Town, deep in the rear of our human kingdom. If the surrounding army units just sense that something is wrong and rush over...!
"...Is what you're thinking, right?"
"!"
H-How did he know?
"You'd better ditch those pathetic hopes. Hehehe. Do you really think I came here instead of staying in the impregnable fortress of the Demon King's Castle without anticipating that?"
Azure skin. Pitch-black sclera. Ram-like horns coiling from his head. No matter how you looked at him, he was a demon. And among them, the strongest of all—the Demon King. A defeated loser like me couldn't possibly resist him.
"It was tantalizing, wasn't it? Just watching us fuck all this time?"
"...What nonsense. I never felt that way."
"Be honest. You were envious, weren't you? After I claimed I'd use you for breeding, I barely even touched you, yet I ravished her right before your eyes. You were jealous, weren't you?"
"Ridiculous."
"Don't pout. This is all the necessary groundwork to shatter that mental fortress of yours and guarantee your conception."
It's fine. Stay calm. As long as my heart doesn't break, I won't get pregnant. And as long as I don't get pregnant, if Saintess Martha or Grand Mage Yuria saves me someday, I can find a way to turn back into a man!
"The sight of you, knocked up and utterly broken... Kuhehe! Just thinking about it makes me giddy!"
As the Demon King chuckled darkly, the robed skull standing beside him spoke in a gloomy, raspy voice. "Your Highness. If you wish to crush her mental barrier, perhaps administering drugs or entrusting her cranial modification to me might be..."
"Shut your mouth!"
Crack!
With a flick of the Demon King's hand, the skeleton shattered to pieces in an instant. But he was a lich. Unless the phylactery containing his life force was destroyed, he was an ageless, immortal entity. The shattered skull fragments gathered back together, restoring his form in seconds. Knowing this full well when he struck, the Demon King merely clicked his tongue.
"This masterpiece was barely forged through my true essence's Feminization Curse, and you want me to ruin her with mere drugs or body modification? The very female who will serve as the breeding vessel for my son?"
"Forgive me, Your Highness. My foresight was lacking."
"Indeed, Sandro. Do not wag your presumptuous tongue regarding my female's affairs. Your share, Grand Mage Yuria, will be handed over to you without fail, so have no fear."
"Yes, Your Highness."
"What?! Yu-Yuria?!"
"Heh, yes. Sandro here has quite an interest in that little Yuria bitch, your former female candidate."
"Quite so. I intend to pop her cranium open personally, massaging and modifying her brains to my liking. You may look forward to it, Erika."
"Y-You bastard! I'll never forgive that!"
Bound in tight ropes while still dressed in my half-torn wedding gown, there was nothing I could do.
"Sandro, notify me the moment that Red Mane Lioness arrives. Until then, I shall enjoy some quality time with my female."
"Understood, Your Highness. Have a delightful time."
I was thrown down onto the luxurious bed inside the finest quarters—presumably the lord's private chamber.
Thud!
"Ugh...!"
Damn it, my head was spinning! As I collapsed helplessly onto the sheets, his massive frame loomed over me, crawling atop my body.

He whispered directly into my ear. "Curious how it felt, aren't you? How that silver-haired thief was ravished just now?"
Slyly, his massive paw cupped my ample tit, kneading the yielding flesh. Ugh, disgusting! I feel like vomiting!
"I'm not... curious at all...!"
"Kekeke. I'll teach you from now on. Since you're my female, shouldn't you experience every bit of the conditioning the other females endure? Only then can you manage the lesser sluts beneath you."
"Let go! Get off me!"
I thrashed and writhed frantically.
"Damn you...! You're the Demon King, yet you're so terrified of a single woman that you have to tie her up to rape her?! Cowardly piece of shit! You have no guts!"
"I'll untie you soon enough. Right around the time you voluntarily wrap your arms around my neck and shower me with kisses."
Remembering how Nina had actually ended up doing just that... goosebumps broke out all over my skin at the terror that it might really happen to me!
"Now then, shall we review what we learned earlier? First, you locate the womb and press down on the lower abdomen like this."
Squish.
"Agh! S-Stop pressing!"
I hadn't been able to use the bathroom in so long that I was barely holding my bladder! Yet this grinning bastard was deliberately putting pressure right on my bladder! Did he really think I'd suffer the humiliation of wetting myself on this fancy bed?! I'll hold it in no matter what!
"An external portio massage is always a delight. It's so amusing watching even haughty elf females lose their composure and wail in shameless delight. And when I vibrate my fingers like this..."
Vzzzzt—!
"Nnn-gh...!"
M-My lower abdomen trembled uncontrollably! His fingers vibrating against my belly felt as though they were forcefully stimulating ovulation right through the flesh! I'm a man...! Yet the organ known as 'ovaries,' which should never have existed inside me, flared with spine-chilling vividness!
"Fuhuhu. I knew you would make lovely sounds. Ah, truly the ideal female I crafted by gathering all my desires. Now, let us turn you into an even finer instrument."
"Shut... the fuck up...!"
What Matters is an Unbreakable Heart
All debuffs have been cleansed!
Fighting spirit surges!
Immunity granted against all curses and mental interference!
"Hahaha! Still so stiff, are we? Good, very good! Even without truth magic, you'll soon be spilling everything on your own, babbling about just how good it feels!"
Vzzzzt—!
"Mmph, ahn...!"
Beyond my lower belly, my uterus was buzzing and ringing! Ah... it felt like the vibrations were echoing straight up into my brain...! A uterus? My uterus?! Damn it, I'm a guy...! I can't yield to this...!
Shit, even as I twisted my body to escape, the sensations crashed in! It was an organ that should never have existed! Yet it felt so terrifyingly natural, as if it had been inside me from the very beginning! No, I have to distract myself! I can't feel this! Ngh, think of something else, anything else...!
Drip.
"What's this? Wet already?"
"?!"
I couldn't help it! Seeing Nina, the sisterly figure I'd looked up to and fantasized about, getting fucked so obscenely right before my eyes... how could my transformed body not get wet?!
"My, my~ A plump little cunt clamping tight, aging and marinating in my seed. Truly irresistible."
Pressing both thumbs evenly into my lower abdomen, he buried his nose directly between my parted thighs.
Inhaaale... exhhaaaale~!
"A deliciously ripe scent... You ought to be stuffed full after drinking down all my seed, yet here you are already drooling cunt juice again. Such a filthy, lewd little body."
"Shut your... filthy mouth...!"
"What a foul tongue. Your thighs are trembling so violently, yet you still put up a front? Relax your mind."
Slurp.
"Ahhn?! D-Don't lick! It's disgusting!"
"Not at all. Yours isn't filthy in the slightest. The scent of your pussy is divine. Just my type."
Gasp, haah. Gasp, haaah!
"Such a youthful slit, soaked through with seed and fermented to perfection. I'd love to impale you right this second, but I'll indulge you a bit first."
Continuing the uterine massage with his thumbs, he peeled back my outer labia with his tongue.
Lick, lick, lick.
"That's it. Peel back your folds and show it to me. Show me that clit of yours."
"Ngh, stop it... stop it...!"
I squeezed my legs together with every ounce of strength I had, but it was utterly useless. Just by wedging his head between them, he forced them apart, his long, serpentine tongue thoroughly unearthing the tightly shut folds of my womanhood. Where a proud cock once stood, only a pitifully vulnerable, tender female sex remained. Petal by petal, my inner flesh bloomed outward, fluttering helplessly like a flower exposed to the elements.
"Ah, the adorable little pearl tucked inside this pretty pink cunt. It's already standing rock hard."
Slurp.
"Ah...!"
Sluuuck.
"Waaah?!"
My hips bucked wildly!
"Just one lick and you're flopping like a freshly caught fish? How precious~ Why is it that you can't even endure a third of what that married woman endured? Ah, is it because you already tasted my cock once? Kuhuhe. I don't blame you for missing it!"
"No, that's... what are you... h-haah, ahn, ngh...!"
Slurp, lick, suck.
This bastard was playing my body like an instrument, knowing every single weak spot as if he could see right through me...! Plundering the swollen bead buried inside my plump folds, prying the shell apart to mine the pearl within!
"Now, here comes a finger. Just one."
Squish.
"Aaaagh...!"
How was a single finger so absurdly thick?!
Stir, churn.
"Dried up a bit inside, I see. Still, with my leftover cum, it's plenty slick. Relax your muscles, girl. Something vastly larger will be stretching you soon enough, so you need to be loosened up properly."
Damn it, stirring inside me and mocking me as he pleased! Filthy demon bastard!
"Right here."
Poke.
"Aaahn?!"
Did he just press beneath my navel?!
"Ah?!"
My back arched off the mattress!
"Fuhuhu. Here it is. Such a delightful reaction. You really are a joy to feast on."
Slurp, lick, sluuuuck!
"...Ngh, ...kh, ...aaah!"
I gritted my teeth, trying desperately to endure, but his finger rubbed relentlessly against the swollen G-spot inside my canal, his tongue flicked over my clitoris, and his other hand vibrated over my womb... Ah, I can't hold out...! Did Nina really endure an entire hour of this?! My entire body trembled! From pure terror, from the involuntary chemical tidal wave of hormones! My body began moving entirely on its own!
Jolt, twitch!
"I know you're excited, but hold still, bitch. With tits this massive, your heart ought to be broader. Endure a little more, won't you?"
Tremble, quiver...!
Led by the symphony of his finger and tongue, my entire body rattled with spasms.
"Mmm."
Chuu.
His tongue! Don't put your tongue inside! I squeezed my pussy shut with all my might, desperately clamping my thighs to lock the gates against his invasion.
"Kekeke. Let's see how long you can hold out, darling."
Damn it, I couldn't let it inside! I had a terrifying premonition that if that tongue entered me, everything would shatter!
Schluuuck!
Slither.
"Nnn-gh!"
It... got in...! God damn it all! Pointing his tongue like a spear, he plunged it straight into my canal, slick with his own lingering semen...! He began churning and probing deep inside!
"Ah! Aagh!"
This bastard was stirring my pussy with his tongue...? Knowing his own seed was still in there, wasn't he disgusted?! Ugh, as he keeps kneading my lower belly, my rear clenches on its own! Clamping down on my slit! Should I tighten up to expel his tongue? Or is it already too late, and I should relax? What do I do?!
Slurp, suckle.
Damn it, his nose kept nuzzling against my clit as he greedily inhaled the scent of my cunt...! Every time he exhaled, hot breath tickled the sensitive bud! And why the hell had he been caressing my... my ass this whole time?! Disgusting! Filthy pervert!
Lick, slurp, lap.
Under the relentless assault of his sharp, stabbing tongue, my inner walls had no choice but to weep rivers of nectar. In the first place, a woman's anatomy was simply too structurally vulnerable to fend off something as slippery and rigid as a man's tongue!
Gulp-sluuuuurrrrp!
"D-Don't drink it! Not my cunt! Don't drink my juiceeeeee!!!!"
Like a starving beast slurping down broth, he drained my honey in a single, voracious gulp... Aaahhh?!
"Ahhh!"
Twitch, spasm, shudder!
"Pwah! As expected of a freshly aged, pristine cunt! Truly worth the taste. I wanted to devour you while you've only been taken once. Hehehe!"
"Ngh, ah...!"
Twitch, jolt!
"What's the matter? Can't hear me?"
Wh-What was this? Fireworks seemed to detonate violently inside my skull... All the strength bled out of my limbs... I couldn't muster an ounce of power... My flesh burned white-hot... Was this a woman's climax...? An orgasm...?
"Did you cum already? Fuhuhu. You held it in all this time while watching that married woman go over the edge over and over, didn't you? Fantasizing and holding back, only to experience it for real—quite vivid, isn't it?"
"~~~!"
Shudder, twitch, throb!
"Ready already? What a lewd little slit. But being this wet on the surface doesn't mean you're drenched deep inside yet. Though forcing my way into a tight, dry passage has its own unique charm."
No. I have to come to my senses, quickly! Why are women so weak? When I was a man, post-nut clarity would snap my mind back immediately, but this female body is utterly fragile! Once I reached the peak of climax, I couldn't climb back down...!
"How should I treat you? Should I impale you first to soak the inner depths?"
Licking every inch of my body with his eyes, the monster swallowed his saliva. Ah, Jamila...! You shouldn't come, but please... come and save me...!
"Let me share an amusing fact with you."
Kekeke.
"The Feminization Curse placed upon your body possesses another special function. And that is..."
He swallowed audibly.
"The more orgasms you experience, the higher your chance of conception becomes."
"!!!"
"Right now, you seem to be holding on with that mental skill of yours, but if you keep cumming over and over, just how long do you think it will last?"
He licked his lips. A gaze that found me truly mouthwatering.
"Before that female warrior arrives, I shall make you cum to your absolute heart's content."
His mouth snapped forward, sinking his teeth hungrily into my breast.
