A Female's Duty Is to Take My Cum
When I opened my eyes, warm morning sunlight greeted me.
Time for my usual morning run, I suppose.
I sat up to shake off the sleep, as I did every single morning. But I soon realized that was no longer possible.
“Haa… That’s right. I’ve become a woman.”
The soft bounce of breasts, the narrow waist, and the long silver hair.
The moment those things entered my field of vision, a deep sigh escaped me. The humiliation I had suffered at her hands the night before resurfaced, and my sigh grew even heavier.
“Is it truly possible to turn a man into a woman?”
No matter how many times I thought about it, it still seemed impossible.
It wasn’t simply that my thirty-year-old son had vanished and my chest had grown larger. My entire body shape and appearance had completely changed.
“This is no time to be lost in thought.”
I was alone in the room. I didn’t know where she was, but the instant she stepped inside, I had to come up with a way to kill her on the spot.
Of course, escape was an option, but no matter what, I would kill the woman who had heaped countless humiliations upon me and then leave this place.
Yet no bladed weapon that this body could easily wield was anywhere in sight. That was when I noticed another door—separate from the one leading outside—firmly shut.
“Ugh… Walking is still difficult.”
With unsteady steps, I slowly opened the door. Inside was an incredibly luxurious bathroom, every surface covered in gold.
Figuring a bathroom would at least have some kind of blade, I looked around—only to freeze when I caught my reflection in the mirror.
“This… is me? How did Argentius Vale, commander of the First Knight Order… become such a frail woman?”
The muscles I had forged over fifteen years were nowhere to be found.
My once-thick wrists, hardened from swinging a sword, were now so slender that one hand could wrap around them completely, thin enough to snap if gripped too hard. My legs were the same.
“Wait… My breasts… Were they always like this?”
I stared at the mirror, sighing repeatedly, and doubted my own eyes.
Just yesterday, both nipples had stood pert and proud. Now they were hidden, tucked inward within the areolas.
“Kgh… I should kill that insane bitch right this instant—”
The sight of my strangely shaped breasts only fueled my hatred for her further. That was when it happened.
Glurk—!!
“Hahuu…♡”
My womb suddenly twitched, and something thick and sticky began to trickle down my inner walls. It soon flowed all the way to my inner thighs. It was the semen she had pumped into me so vigorously the night before.

“How… is it still inside me?”
Once it started pouring out, the cum refused to stop, completely coating my thighs in a thick, milky white.
No matter how viscous it was, it shouldn’t have remained inside me until the next morning.
“Did you sleep well, Aria?”
A woman’s voice came from behind me. I spun around in a panic. There she stood, wearing nothing but a bathrobe like yesterday, arms crossed.
“Smooth out that face. You’re ruining your pretty features.”
“Shut your mouth. When I think about what you did to me yesterday…”
“The only time your face is allowed to twist like that is when you’re taking my cock. I won’t permit it any other time.”
Her flaccid penis swayed heavily against her thigh with a lewd smack. The grotesque motion made me look away, but she had already closed the distance. Her fingers gently seized my chin, forcing me to meet her gaze.
“You looked so fuckable while you were sleeping soundly that I couldn’t hold back.”
“What did you just say?”
“So I filled your agabang with a few more loads of jot-mul while you were out. Even in your sleep you were moaning and squirting like a whore.”
“You… crazy bitch…!”
I clenched my right fist and swung. She watched calmly, then caught my wrist with surprising gentleness. With a smooth twist, she spun me around and caught me by the waist.
“You will never defeat me, Aria.”
“I will kill you without fail.”
“Mhm. I’ll be looking forward to it.”
The hand that had gripped my chin slid down my neck and settled on my breast.
“Huu…♡”
“I’m not sure you could kill me when just a light touch to your tits makes you moan like that.”
She traced slow circles around my areola, then slipped her fingertip into the hidden cleft where my nipple lay buried.
“How can your breasts be this lewd? I never intended to give you inverted nipples, you know.”
“Let… go…♡”
“Actually, I like it. It means I can tell at a glance when my little female is in heat just by looking at her chest.”
She pressed both sides of my areola, forcing the hidden nipple to pop outward, then immediately pushed it back inside again.
“Haaahng♥”
That alone sent a shiver racing up my spine and drew a shameful moan from my lips. I despised this body that grew so wet between the legs from such trivial stimulation.
“Let’s eat breakfast.”
She took my hand and led me out of the bathroom. Before me was an extravagantly luxurious breakfast spread.
The glass of fine wine glowed with a color I had never seen in my life. The steak beside it possessed an aroma and presentation that put the simple slabs of meat I used to enjoy to shame.
“Eat up, Aria.”
All of this was food I was allowed to consume.
Part of me insisted I must reject everything she offered, but my body—confronted with dishes it had never tasted—proved far too honest.
“Gulp…”
“Looks like your mouth is watering. You haven’t eaten since last night, so feel free to eat as much as you want. Tell me if it’s not enough.”
She even pulled out the chair for me beforehand and helped me sit.
My eyes fell on the fork and knife in front of me. Right now, I could drive them deep into her throat.
Growl—!!
The moment I seized the utensils with murderous intent, a loud rumble from my stomach instantly shattered my resolve.
“Pfft! You must have been really hungry, Aria.”
“Th-this is… I mean…”
“It’s fine. It’s only natural. There’s no need to be embarrassed.”
I stared at her gentle, smiling face for a moment before looking back down at the steak.
Another rush of saliva filled my mouth, and the fork and knife moved on their own.
“I’ll… eat well. Mmph…!”
The polite phrase slipped out unconsciously. I immediately clapped a hand over my mouth.
If I say that, it sounds like I’m meekly accepting her hospitality.
She smiled warmly at my reaction.
“How polite, Aria. I’d love it if you were just as well-mannered when you take my cock.”
“Th-that will never happen.”
I glared at her with a slight frown, then placed a neatly cut piece of steak into my mouth.
“Mmm?! I-it’s delicious…”
The moment it touched my tongue, it melted away like butter. The perfectly balanced sauce and rich, living juices harmonized in my mouth so perfectly that my eyes nearly bulged out of my head.
“If you stay by my side, you can enjoy meals like this whenever you want. Doesn’t that tempt you?”
“Don’t think you can win me over with mere food.”
“If that’s how you feel, why don’t you wipe the sauce from the corner of your mouth first?”
At her words, I hurriedly dabbed my lips with the napkin beside me. Nothing came away.
“You lied.”
“You rotten bitch…”
She chuckled and lifted her wine glass, offering it toward me.
“A toast to your bright new life as a female.”
“I have no reason to clink glasses for something like that.”
I drank the wine without touching her glass. The moment it flowed over my tongue, my eyes widened again.
“It’s sweet…”
It was without a doubt the deepest, richest flavor I had ever tasted in wine.
It couldn’t even be compared to the vintages I had drunk at noble banquets.
“A commander of the First Knight Order must have enjoyed such luxuries before, no?”
“Unlike the other commanders, I was born a commoner. That’s why, aside from my own subordinates, none of them ever truly accepted me.”
“How pitiful. Don’t worry. If you stay by my side, you’ll enjoy wealth and honor that no noble or royal could ever match.”
“Nobles are one thing, but even royals?”
“I happen to know the filthy secrets of the royal families of most nations quite intimately.”
She waved the sauce-stained knife in front of my eyes before using it to slice more steak.
Since I didn’t know the inner workings of the Rosenberg family, her confident statement raised many questions.
I answered her occasional questions curtly or not at all, and the breakfast eventually came to an end.
“Did you make this yourself?”
“No, I have someone who prepares it for me.”
“Does that person know about your disgusting hobbies?”
“Yes, they do. They’re a failure, after all.”
A failure?
“Exactly how did you turn me into a woman?”
Killing her was my top priority, but gathering information was equally important. I needed to pry every detail from her and find something I could use as a weakness.
“Trade secret.”
“Then were you born a hermaphrodite?”
“Did you think it just popped out one day? Of course not. I’ve had it since birth.”
She stood up and casually dropped her cock onto the table with a heavy thud. The appetite that had been stirred by the delicious steak and wine died instantly.
“Aria, say ‘cock’ for me.”
“How dare you ask me to utter such a vulgar word.”
“Looks like I really have to teach you everything from scratch. Normally I’d just leave it to the failure because it’s such a hassle, but…”
She suddenly leaned in close, her face inches from mine.
“I want to watch with my own eyes as the former knight commander slowly turns into my perfect little female.”
“Kgh…! Shut up!”
I clenched my fist and swung, but she dodged like an eel.
Then she placed a single pill in the palm of my hand.
“Swallow it.”
“Why should I trust anything you give me?”
“You don’t have to if you don’t want to. Not if you want to carry my child, that is.”
I could hardly believe my ears.
No… what she said was only natural.
With that much semen poured into my womb, pregnancy was inevitable.
To bear the child of the woman who had forced such humiliation upon me… I wanted to avoid that at all costs.
“Tch…”
With no choice, I swallowed the pill along with some water. At that moment, the woman drew closer and grabbed my wrist.
“When you truly become my female, that will be the day you carry my child.”
“I’ll rip that filthy mouth of yours off right now—”
Just as I was about to unleash the torrent of rage and disgust boiling inside me, she yanked my wrist and dragged me toward the bed. She climbed onto it while I was forced to sit on the floor.
“Are you trying to make my cock angry first thing in the morning?”
“What are you talking about?”
“Your pussy is completely exposed.”
I looked down. Because I had been sitting cross-legged as usual, my privates were fully visible.
“Eek…!”
I hurriedly covered myself with the hem of my nightgown and pressed my thighs together.
“That little squeak was very feminine, you know.”
I looked up at her with a scowl, only to be met with the sight of her spread legs, her balls and cock shamelessly on display.
“From now on, we’re going to have a special lesson just for you, Aria.”
“A lesson?”
“I told you. I have to teach you everything from one to ten.”
She smiled as she slowly stroked her cock from the glans down the shaft to the base, over and over.

“I’ll start by teaching you how to get my cock hard.”
“Y-you expect me to do something like that?”
“Of course. You’re my female now. You can’t just assume my cock will always be rock hard for you.”
I bit my lip hard and tried to stand up.
Snap—!!
At that moment, she flicked her fingers lightly. The sound echoed through the room, and strength drained from my legs as my lower belly began to throb violently.
“Huuu…♡”
“A female’s duty is to be ready to receive her master’s jot-mul even when he isn’t prepared.”
“Just what… did you do to this body…♡”
Instead of answering, she simply smiled and gently stroked my hair.
“Do a good job and I’ll reward you. Fail, and a very painful punishment will be waiting.”
