The Archmage, Kim Seo-yul
"Mmm, good. Not bad at all. Your prostate is steadily taking on the role of a mana hole. Keep this up and we'll have it down in no time. Heh, not bad, right? See? You can do it when you try."
"Haah, haah... Y-Yes. Thank you, Master. Nngh, ah..."
It had been so long since Master had praised me. Because the fruits of my training were finally showing, I should have felt overjoyed and proud, but I quietly averted my gaze, evading her eyes.
The reason, of course... was my behavior over the past few days.
Every night, cutting into my sleep, I had masturbated anally. Terrified that Master might overhear my vulgar, lewd whimpers, I had bitten down hard on a towel stuffed into my mouth. Gradually tweaking the way I did it, I grew increasingly accustomed to the pleasure. At first, I held the dildo and thrust it in myself to bring my rear to heat. And the moment that aroused, inner anal flesh swallowed and pushed the toy back out of its own accord, I hugged my knees tightly to my chest and reveled in blissful orgasms.
The effects of the anal masturbation were astonishing. With every passing day, I could genuinely feel my prostate establishing itself as a mana hole. A training method tailored specifically for a femboy—awakening the prostate to serve as a reservoir of mana.
Yet, could this truly be called training?
"Ugh, haah! Aahh, ngh. H-Hiii♡ Haa, aahhnn♡"
Lying on the bed with a dildo buried in my rear and a towel clenched between my teeth, trembling all over as I surrendered to violent orgasms—how could anyone call this training?
Dry orgasms that raised goosebumps across my entire body and felt as though they would melt my brain. And, subtly distinct from that, an intense pleasure that made bestial moans spill out unbidden, sending ripples through my whole body until I could barely breathe.
When I looked it up later, I found out this sensation—distinct from a dry orgasm—was known as the defecation reflex. The act of inserting something into the anus to stimulate the rectal wall and force that reflex, wringing pleasure from the body. And the things people put inside naturally boiled down to two choices: dildos or cocks.
"Nngh, c-cock... A-Anal sex..."
To have sex using an anus. Until now, even with Master's fingers entering me and the dildo staying inside, the idea of having sex with an anus had never crossed my mind. Why use a place like that when you have regular genitals? S-Sure, anal masturbation felt amazing, but this wasn't normal. I was only doing it out of necessity, for the sake of my training.
"Ngh, aahh..."
Bzzzz...
The dildo vibrating within my rear and grating against my prostate coaxed an embarrassing moan past my lips. I had only just managed to get used to the lowest setting, yet Master had immediately bumped the intensity up a notch. As a result, my legs shook uncontrollably, and my lower abdomen throbbed with continuous, aching pulses.
"Haah, n-no. Today I really need to practice my swordsmanship. I lack Master's talent. If I want to keep up with her even a little, I have to put in blood, sweat, and tears. Hah, n-no more anal play, today I really must train..."
Squelch, squelch. Slurp, squick.
Schlick, schloop! Plop, squelch!
"Ngh, haah! Eep, hyiiik♡ Hck, hah, aah. Ooh, ngh! Haa, it's so good... My butt feels so good♡ Ahh, I'm cumming... I can't stop cumming♡"
"Going out?"
"That's right. Let's go outside for a change of pace; it's been a while. You've done nothing but train at home lately, and since you've shown results, consider this a reward from your master."
Aside from tackling gates, I had stayed cooped up at home training for weeks, so a sudden outing caught me by surprise. Summer had come to an end, sweeping away the oppressive heat, so a walk outside would certainly be refreshing.
"Well then, how about we wash up before heading out?"
Whoosh—
"What are you waiting for? Hurry up and wash."
"Y-Yes."
Saying she was going to shower, Master grabbed my hand and dragged me into the bathroom without asking. Before I could utter a word of protest, my clothes were stripped away, my chastity cage and dildo unlocked and removed, and I was pushed beneath the showerhead. Utterly devoid of shame, Master stood casually before me under the warm spray, lathering soap across her entire body.
Two large, gorgeous breasts and a slender waist. Wide, seductive hips tapering down into shapely thighs and an ample rear. And dangling flaccid between her legs, yet still radiating an imposing, violent presence due to its sheer size—a massive cock...
I stole glances at Master's body as I began washing myself. Every time my soapy hands touched my lower belly, my penis, and my rear, a strange sensation washed over me. The devices that had resided inside my urethra and anus for nearly a month had been removed, granting me a brief taste of freedom. I thought I would be ecstatic, but now that both contraptions were gone, an unexpected emptiness flooded in.
Ngh, why am I like this? Is it because I wore them for so long? The feeling of my urethra and rear being empty feels so bizarre. Hngh, ahh...
Bathed in that strange, hollow liberation, I finished showering and was about to get dressed when—
"Ah, hold on. Put this on."
Master, who had finished washing and left the bathroom ahead of me, held out a bundle of clothes. What I received was women's clothing. A white, short-sleeved crop top that completely bared the midriff, paired with tiny black hot pants that left almost the entirety of my thighs exposed.
"Uh... pardon?"
"If you wear this, I'll let you go without the chastity cage and the dildo for the whole day. We can go outside and have fun without you having to worry about them."
Master flashed a bright, toothy grin.
"Y-You want me to crossdress and walk around outside all day?"
"Mmm, don't think of it as crossdressing—just think of it as wearing pretty clothes. Well? Sounds great, doesn't it?"
"...N-No. I'm fine. I'd rather wear my chastity cage and dildo with my usual clothes."
"What?"
The radiant smile revealing Master's white teeth vanished in an instant, replaced by an expression of bone-chilling coldness.
"Are you refusing to listen to me?"
"N-No, it's not that. Clothes like that are just a bit... I-I'm so—"
"Enough. Put this on quietly. Otherwise, you'll wear this outfit while keeping the chastity cage and dildo in, cranked to maximum output the entire day. Pick one."
"N-Nngh, that's not fair!"
It was pure tyranny. Yet, as always, I lacked the power to resist.
"Okay..."
"Fufufu~ Good, let's go♡"
My first outing in a long time. And to make matters worse, I was crossdressing, linking arms and clasping hands with Master like a couple. At first, my heart was in my throat.
'Ugh, what is that? Must be insane.'
'A freak walking around in broad daylight crossdressed? Keep that disgusting kink locked in your own room!'
I was terrified someone would see through my disguise and hurl insults like that. Yet, somehow, nothing happened. To onlookers, we merely looked like two women with a noticeable height difference strolling arm in arm. I even ran into a woman when we went into the ladies' restroom, and absolutely nothing occurred!
"Fufu, see? What did I tell you? I told you it'd be fine. Ha-on, with just a little styling, you're a born woman. A cute little girl I just want to wrap my arms around and never let go."
"Ngh, p-please stop. Let's get out of here quickly. Someone's really going to notice at this rate."
Master had even made the insane suggestion that as long as I kept my panties on, nobody at a women's bathhouse would realize either, so we should go there next. I had to bodily shove her out of the ladies' room.
Haah, haah, this is exhausting. Getting some fresh air and eating delicious food after being cooped up is wonderful, but the constant dread of being found out is driving me out of my mind! Uwaah!
We finished lunch, and as I tried to calm my racing heart while walking through the park, a voice called out:
"Huh? Horse-Cock? And next to you... Ha-on? That is Ha-on, right?"
"Oh, for fuck's sake. What rotten luck, running into this bitch on the street. Did you stalk us here, you wretched cunt?"
"My, my. Look whose mouth is as foul as the monstrous thing dangling between her legs. What kind of master talks like that in front of her disciple? You horny horse-cock."
"You fucking bitch, you want to go?!"
"Ah, p-please stop, Master! You too, Noona! Why do the two of you have to fight the second you see each other?!"
"Didn't you see, Ha-on? You heard what this bitch just called me!"
"Haa, truly devoid of grace. Ha-on, don't stick around with a horse-cock gorilla like that; come over here. Hang out with Noona."
A red-haired woman smiled leisurely while looking down her nose at Master, baiting her with provocation. A former member of the party that had once saved the world, the bearer of the title Archmage, and the Tower Master of the Silver Magic Tower. Though they had been comrades, she was now Master's bitter nemesis, with whom Master clashed every single time they crossed paths—Kim Seo-yul.
"Shoo, shoo! Get lost. Scram! Come on, Ha-on, let's go!"
Looking thoroughly repulsed, Master backed away from Seo-yul Noona and yanked me along.
"Ah, g-goodbye, Noona."
Attempting to maintain some semblance of manners, I hurriedly offered a bow and tried to take my leave, but—
"Where do you think you're going? Pfft, running into each other like this is fate. Let's hang out together."
Seo-yul Noona dashed forward and snatched my other arm from Master's opposite side.
"Y-You fucking whore, I swear to—!"
After bickering back and forth for a while, the three of us ended up walking together into a café. In a café filled with soft music, we were supposed to be savoring the rich, aromatic scent of coffee and enjoying sweet cake. Or so it should have been... but wedged between Master and Seo-yul Noona, walking on eggshells, I couldn't care less about the smell of coffee.
"Hmph. Wandering around a park in broad daylight. Must be nice having nothing to do."
"My subordinates are competent, you see. All I have to do is sign off on documents and offer advice now and then."
Having effortlessly deflected Master's jab, Seo-yul Noona turned her eyes toward me.
"Have you still not fixed that habit of doing whatever your dick pleases? Why put women's clothes on our handsome, dashing Ha-on? I don't even need to ask; you threatened poor Ha-on into wearing them when he didn't want to, didn't you? Right, Ha-on?"
"Huh? Ah, w-well, you see, that's..."
She hit the nail right on the head, but with Master glaring daggers at me as if ready to murder me on the spot, there was no way I could speak the truth.
SLAM!
Master slammed her hands onto the table and abruptly stood up.
"Fuck, this is annoying. I'm so pissed off I need to wash my face. Move!"
Pushing past me, Master stormed off toward the restroom.
"Phew. You certainly have your hands full with her."
"Ha... haha, not really."
Just the two of us remained at the table. Swirling her coffee with a straw before taking a long sip, Seo-yul Noona flashed a mischievous grin and spoke to me.
"By the way, how are they?"
"Pardon? What are?"
"Those things. The chastity cage and dildo you've been wearing."
My heart plummeted straight into my stomach.
"Ah... H-How do you know about that?"
"Pffft♡ How else? Because I made them. Who else could carve such intricate magic circles into such a tiny space? So, how were they? Are the effects good? Did it hurt when you first put it in? Ah... are you wearing them right now, by any chance?"
Licking her lips, Seo-yul Noona scrutinized me with intense fascination. For some reason, that predatory gaze felt eerily similar to Master's.
