Sexual Processing, I Shall Begin
Finally, Hyemi noona stepped out of the bathroom and let out a startled gasp as she took in the scene. The hallway drenched in sticky jade-colored mucus, me standing there, and Yunsol wearing the mask. I waved her over as she froze awkwardly in the bathroom doorway and shifted the limp Yunsol into her arms.
“What happened to her? How did Yunsol end up putting on the mask? She’s turning into an ‘Ideal Saintess’ too.”
“...Like you, noona? This is bad, especially at school… For now, I’ll clean up this mess before anyone shows up. Noona, just look after Yunsol until she wakes. I’ll handle the cleaning.”
I left Hyemi noona as she knelt in the hallway and laid Yunsol across her lap, then grabbed a mop from the cleaning supply closet by the bathroom entrance and started wiping up the pools of mucus. No matter how hard I pushed, the stuff refused to come clean. I was grunting with effort when a small voice rose behind me.
“Huh…? Yunsol… ah…?”
It was Hyemi noona’s voice, laced with uncharacteristic panic. Even I was caught off guard. That fast? It hadn’t even been a full minute since Yunsol put on the mask. This morning Hyemi noona’s change had been instantaneous, but I never expected it to be this quick…
“Wait, already? Yunsol—”
“......”
I should have noticed the shift in Hyemi noona’s tone. I spun around, voice bright with relief, but the words died in my throat. Yunsol, who had been lying across Hyemi noona’s knees, was slowly sitting up as she peeled the mask from her face. She picked up her glasses from the floor and settled them on her now coldly sharpened eyes.
“...Yunsol, is that really you?”
“──Yes, it is.”
Hyemi noona was even using honorifics with the completely transformed junior, her voice full of bewilderment at the adorable underclassman’s new demeanor. Yunsol answered in a crisp, precise tone, adjusting her glasses as she looked down at her senior. The change left me speechless too.
Her black hair, which had reached her shoulder blades, now cascaded all the way to her hips in glossy waves, streaked here and there with strands of pure white. A single horn jutted from the left side of her forehead—unlike Hyemi noona’s pair—catching in her long hair. Her eyes had turned into black sclerae glowing with an even deeper jade hue. The once gentle, timid Yunsol who always hunched her shoulders now stood tall and confident. The mouth that used to curve into a polite smile for everyone was now frozen in a chilly line.
“...Fascinating. My mind feels remarkably clear.”
“...Woojoo, her speech pattern got all stiff too…”
“Quiet for a second, noona.”
She even seemed taller. Yunsol, who had been in the upper 150s in height, now looked a few centimeters taller. It wasn’t just better posture—her frame had genuinely grown by about five centimeters. The only things that hadn’t changed much were her breasts and hips. Those had already been excessively large… But the soft fat on her thighs and belly had vanished so completely it was visible at a glance.
In short, she had become a cool, elegant beauty with the perfect balance of voluptuous curves and ideal proportions. A body radiating such scorching heat that it was impossible to contain the cold yet overflowing sensuality. One hundred and eighty degrees from the Yunsol I knew.
“Master— No… Did my owner desire this body and personality from me…?”
“...Woojoo, what the hell else have you been watching besides succubus stuff?”
“I honestly don’t remember either…”
But the real reason both noona and I were breaking into cold sweat was the atmosphere. The puppy-like Yunsol who used to laugh off teasing with a silly “hehe” had completely vanished. Instead—
“...To be honest, I’m displeased.”
“She just said she’s displeased…!”
“Why is that my fault…? And why are you suddenly speaking so formally…?”
Her aura had grown so icy it overwhelmed even Hyemi noona. Was this really the Saintess I had once held as my ideal? What the hell had middle-school me been fantasizing about?
I instinctively looked away from Yunsol, who was staring straight into my eyes with a dry, emotionless gaze. It felt like standing in front of that terrifyingly strict homeroom teacher from my middle-school days. I set the mop down.
...Wait. Come to think of it, Yunsol’s new hairstyle and aura were exactly like that teacher’s…
“Ah, I remember now.”
“I’m glad you remember, my owner.”
“W-what? What is it?”
Yunsol let out a small sigh as she approached. Her breasts swayed heavily with each step.
“In middle school, there was a female teacher who tormented the students mercilessly. She was young and beautiful, but her personality was vicious and cunning.”
“.......”
“When one of my friends received unfair punishment for something trivial and complained about it, my owner and his friends came up with a rather petty revenge plan.”
Yunsol walked toward me, calmly explaining the “ideal” that had reshaped her—just as Hyemi noona had done earlier.
“The second volume of the succubus-concept AV my owner kept hidden was titled ‘The True Identity of the Coercive Beautiful Secretary Is a Succubus.’ The actress in it looked exactly like my owner’s homeroom teacher. Appearance, personality, even that domineering tone. It seems the ideal my owner longed for has seeped into me.”
“...Oh, I was the first volume.”
“Will both of you please be quiet…”
My face burned scarlet from the unfinished public execution. I stumbled backward until my back hit cold concrete. There was nowhere left to retreat. Yunsol didn’t stop. She kept advancing until her breasts pressed firmly against my stomach. She tilted her head up to look at my face.
That scent again. The one that melted reason and left only raw male instinct. My cock, already hardening inside my pants, brushed against her. She glanced down, gave a short scoff, and spoke.
“...My owner wished to see that arrogant woman’s composure and solid pride crumble. He wanted her impaled on his cock, sobbing in a female voice and submitting completely. To think the kind Woojoo-oppa had such a past…”
“...That was just a silly mistake from puberty… um…”
“It’s fine. I felt a little contempt, but I’m grateful to you. Because I became a Saintess, because you continued to cherish those filthy desires for domination, I obtained what I wanted. Your ideal reacted to my self-loathing—the belief that ‘I hate being ignored and used because of my timid personality.’ Thanks to that, revealing myself no longer feels frightening.”
A faint blush colored her cheeks as her jade tongue flicked out, dropping a thick strand of saliva into her cleavage. I felt her hand glide over my pants, stroking my fully erect cock.
“Haa…! Y-Yunsol…!”
“My, you seem to be struggling. This is the effect of the alluring scent we Saintesses emit. It can’t be helped. Since this body was created to satisfy your vulgar desires, I’ll assist you this once…”
“Huh? If Yunsol doesn’t want to do it, I can take over.”
“...I’ve always wanted to say this, but, unnie, learn to read the room.”
“Eep…”
Hyemi noona froze solid at Yunsol’s icy glare. Ignoring her, Yunsol looked back at me, summoned her tail, and used its sharpened tip to slice my pants open. My belt snapped in two, and my pants and underwear slid down at once. My rigid cock was now exposed in the middle of the school hallway…
“...It certainly is a useful tool. Since you turned me into this body, you should at least help relieve the stress I’ve accumulated until now. Who knows? Having inherited the appearance of that secretary from the AV you watched, I wonder if you can truly turn me into a sobbing, whimpering female…”
“Haa, haa…!”
The alluring scent the Saintesses emitted was incredibly dangerous. My mind refused to work properly. Even though I had already cum ten times that morning, my cock was leaking precum at the sight of her seductive body.
Yunsol lifted her skirt, slipped off her panties, turned around, and bent at the waist, sliding my cock between her ass cheeks.
“W-wait, Yunsol! This is the hallway—if someone walks by…!”
“That would certainly be troublesome. However, that is not my concern.”
Squelch─♡
“Huk…!”
Her pussy looked completely dry from the outside, yet the moment my cock parted her fleshy walls, hot love juices dripped to the floor. The mucous membrane swirled around my entire length, stimulating every inch. Unlike Hyemi noona’s pussy, which had squeezed and milked me with tight spasms, Yunsol’s was soft and enveloping, like a warm embrace. The pleasure melted my lower body and threatened to turn my brain into mush.
“Haaat…! Kgh…!”
“I’ve only just inserted it and you’re already making pathetic noises? Put in more effort. At this rate you’ll never make me cry, my owner.”
Even though my glans was grinding against her cervix, Yunsol’s expression didn’t change in the slightest as she looked up at me with those cold eyes. Just how drastic could a personality shift get? What the hell had the mask done this time…?
“That’s enough. I will move on my own, so please simply enjoy my service, Master. An expressionless succubus secretary handling her owner’s sexual needs—isn’t that exactly your ideal?”
Schlick!Plap!Squelch!
Obscene, wet sounds echoed down the hallway. They were loud enough for anyone nearby to hear. I had to stop her. I had to grab Yunsol’s waist before someone came this way…
“Khrrk…!!”
My body wouldn’t listen. The pleasure felt like dozens, hundreds of soft silk threads wrapping around my cock, locking every muscle in place. The sweet scent piercing my nose erased my reason like alcohol. Yunsol’s gaze as she looked down at me, the anxiety of possibly being caught—everything tightened around my chest.
In the end—
“I’m… cumming…! Ukh…!!”
Spurt, spurt. Thick semen surged through my urethra and flooded Yunsol’s insides. She paused at the heat invading her lower belly, breathing perfectly steady as she stared into my eyes.
“...Is that all?”
Her arrogant, haughty tone was an obvious provocation. She kept my cock clenched inside her and wiggled her hips teasingly. Though her face remained blank, her eyes held a glint of expectation as she stared at me. I grabbed her ass and yanked her back down.
My cock, which had slipped out slightly, plunged back in with a vulgar wet sound, splitting open the hole that had known no man until recently.
“...Huu, huu…”
“...Yes, use me however you wish. This secretary pussy exists only for Master…♡”
