Anal Development Plan
The vehicle prepared by headquarters for agents with business in the nearby city hummed quietly. I stared out the window at the brilliantly shining sky, replaying the words of the Yumekawa agent in my head.
Why? Why did that woman named Harumu keep bothering me so much? I knew my own personality best—the one that had zero interest in others and felt awkward about new relationships. Out of all the companion agents I’d met during missions, the only one I’d ever had a personal conversation with was Kwon Noa. Even then, it was only because she’d forcibly dragged the annoyed me into talking…
Anyway, the face and eyes of ‘Yumekawa Harumu’ refused to leave my mind. Was I feeling threatened by her? Or was it pity?
Ever since the meeting with the Yumekawa agent and the branch director, my mind had been restless.
“Oh, it’s Sister Luna. In civilian clothes… Her nun habit is cute, but casual wear looks good on her too…”
“What? Really? Now that you mention it, I think I heard she was going out today.”
“She’s so cute… So pretty… The reincarnation of the Holy Mother… I want her as my girlfriend… Mmph?!”
“Shut up. Isabelle’s riding in the back.”
The bus grew noisy with small sounds. Following the male agents’ voices, I looked out the window.
There stood Luna, no longer wearing her usual black veil and enveloping nun habit. Instead, she was dressed in neat yet casual outing clothes, holding a leather case in one hand and smiling sweetly as she greeted the agents lined up.
“….! ──!”
She must have noticed my gaze from the back of the bus. Luna turned around, broke into a wide smile, and mouthed words while waving enthusiastically.
When I smiled faintly and waved back at her lively greeting, she waved even more vigorously.
But at that rate…
Thud─!
The case, shaken by her vigorous movements, slammed into a roadside tree beside her with a dull sound. The impact must have undone the latch, because Luna’s belongings spilled out in a chaotic heap.
What on earth did she pack…?
I let out a sigh as I watched her face turn pale with panic, frantically gathering her things with her small hands.
“Wow, Sister Luna dropped all her stuff… Looks like she’s going on a picnic or something.”
“More importantly, look at those guys who were in line swarming her like a pack of dogs to help. Pathetic bastards trying to score points without even knowing who’s on this bus.”
Just as the man said, carefully lowering his voice while watching me.
The men who had been staring at Luna the moment she appeared at the end of the line—more precisely, at her chest and hips. Even the ones who had sneakily glanced at her cleavage while picking up her spilled belongings. I memorized every single one of their faces.
No one is allowed to look at my family with those eyes. That right belongs solely to my Master.
I couldn’t let them lay their gazes on bodies that would one day serve Him together.
I opened the window and called out to Luna, who was hurriedly trying to lock her bag again.
“What did you bring so much of? Luna, get on quickly.”
“Ah, haha… This is still a secret. I’ll tell you later!”
“Alright, then…”
I smirked and secretly shifted my gaze toward the men. As if nothing had happened, they stood in a perfectly straight line again, deliberately avoiding my eyes. A few of them were even breaking out in cold sweat as they yielded their spots to Luna.
Luna, who had been awkwardly refusing their offers, ended up accepting concession after concession. Thanks to that, she went from the very end of the line straight to the seat beside me.
“…Isabelle, you didn’t say anything harsh to those people again, did you? They’re reliable and good colleagues. We should always show them respect.”
“I’m not so sure about the ‘reliable and good’ part.”
I looked at Luna, who was resting her chin on her hand and scolding me with a faint smile. If those bastards had dared to feast their eyes on her body, then yielding their spots was the least they could do. Luna, who was oblivious to lustful gazes, probably had no idea she’d just been ogled with impure intentions.
I decided that the faces I’d memorized would be kneaded like pizza dough during the next regular sparring session…
We will now depart. Any leakage of classified information to the outside will result in appropriate disciplinary action…
The familiar announcement played alongside the rumbling engine. The scenery outside began to move little by little.
Inside the bus that had finally departed, the trembling of one agent mixed with the heavy silence of those blankly staring out the windows.
The first stop we would soon reach was the public cemetery—a place for agents who had lost lovers, family, or comrades.
It was also the destination of Luna Kang and Isabelle Kang.
“Hello, Daddy~ Your daughters came to visit!”
With my hands in my pockets, Luna placed the bouquet of flowers she’d bought at the cemetery entrance on her father’s tombstone. I followed her as she clasped her hands together in prayer, closing my eyes and quietly offering my thanks.
Thank you for saving me. Thanks to you, I was able to meet my current Master.
I poured more sincerity into the greeting than ever before. When I opened my eyes, I saw her beautiful profile still deep in prayer.
A gentle, porcelain face like sunlight. That face, which seemed carved from the word “peace,” carried a faint trace of loneliness and sorrow.
She was the bloodline of my benefactor—different from me. I hated seeing the sad expression on the face of the daughter he had cherished so much.
So right here, I swear to you, Father.
I will definitely make Luna happy.
I will rescue her from the god who keeps betraying her faith and lead her to the supreme happiness a woman can feel.
Beneath my Master. Together with me. Forever.
Living a life of serving Him for all eternity…♡
“Huu… Ngh…♡”
“Huh? I-Isabelle…? Are you crying…?”
“Ah, no… The cold wind just startled me for a second…”
I had unconsciously slipped my hand down my pants. Startled by Luna’s voice after she finished praying, I quickly hid my hand behind my back and gave an unusually flustered reply.
Luna…
“Mmm, it is a bit chilly even though it’s summer, isn’t it? Maybe because we’re in the shade…”
She hadn’t noticed. Thank goodness it was Luna beside me…
“Anyway, Daddy, Isabelle and I are doing really well, so don’t worry. We’ll come again next time, okay? Oh, right. Isabelle has another mission coming up, so please watch over her!”
Luna forced cheer into her sad eyes as she grabbed my hand and brightly shouted, “Let’s go!”
Pulled along by her hand, I left the cemetery and walked quietly along the long promenade.
I was wondering what story to bring up and when, when Luna spoke first.
“…Isabelle, you haven’t had lunch yet, right?”
“We left right after the meeting… So no, not yet.”
“Then, ta-da!”
Luna trotted over to a bench in the middle of the promenade and opened the leather bag she was carrying. Inside were a picnic blanket that had rolled around and gotten dirty, along with lunchboxes covered in scratches.
I had already seen them when her luggage spilled at the bus stop earlier. Should I pretend I hadn’t…?
In the sudden situation, I scratched my cheek and approached, opening one of the lunchboxes.
Slightly crushed sandwiches and fruits that had gotten mixed together. I shifted my gaze from the lunchbox that looked like a battlefield back to Luna.
“…It wasn’t like this originally. Really. I swear.”
“I haven’t said anything yet.”
I sat down beside Luna, who was waving her arms in embarrassment, and looked at the lakeside spread out before us.
The path I used to run often while receiving training from my adoptive father, and the sparkling lake. So this was all that remained of the memories here.
As I stood on this hometown land that no longer held even a trace of affection, lost in thought, Luna carefully handed me a sandwich.
“It’s been so long since we had a picnic like this together, hasn’t it? Was the last time last year…?”
“About 378 days ago?”
“You even remember the exact number…?”
I smiled silently and took a bite of the sandwich she handed me. By then, the sun was already setting.
The number of people walking the promenade had decreased, and the streetlamp beside the bench flickered before pouring out its light.
“It’s already this late… Should we head back? You should go rest too, Isabelle…”
“No, let’s sit a little longer. There’s something I’m waiting for.”
“…Waiting? For what…”
It was almost time for the last bus heading back to headquarters, but I didn’t stand up. The warning sign I had seen when entering the cemetery earlier. According to what was written on it, it would happen soon.
Rustle─
“…Ah, mmm… Oooh…♡”
A sweet voice and rough breathing came from somewhere. The grass surrounding us rustled, and darkness fell over the park’s daily life.
The warning sign I had just seen had a short phrase written on it: “Indecent acts in the park are prohibited.”
Because it was close to the public cemetery, few people visited this place at night. But for perverts who enjoyed the thrill of being overheard in their obscene acts, this place must have been a holy site.
I never would have thought this promenade was such a place.
“…This sound, no way…”
“………”
As expected, Luna’s face turned bright red with great embarrassment. She quietly lowered her head and pressed her lips tightly together like a child who had done something wrong.
…As I thought, she isn’t running away.
The possession from last night seemed to have had some effect. If it had been the original Luna, she would have dragged me away by the hand or shouted, “Th-this kind of thing in a park is impure!” But now…
“…Aah, ngh…! Haaang…”
“…Ugh…”
Every time the moans grew more intense, she lowered her head further and tightly gripped the hands resting on her knees.
The same voice she had let out last night. What kind of pleasure was she feeling to cry out in such a voice?
I glanced at Luna, who couldn’t get up from her seat because of that curiosity, and smiled faintly.
“…Isabelle, that…”
“……”
“Isabelle…? Huh? Isabelle, what’s wrong all of a sudden? Isa─ Eek?! Ah…”
When my flickering vision refocused, I saw Isabelle—my own body—leaning against the bench, asleep.
Today’s possession had gone much more smoothly than yesterday. And I could move Luna’s body even more easily.
Using Luna’s hand, which moved exactly like my own, I clenched and unclenched a fist before standing up. Then I approached my sleeping body and pulled a small object from the inner pocket of the clothes I was wearing.
A small anal plug. Black, with a blunt tip and appropriate curves.
It was something I had originally bought out of curiosity to use on myself, but I never imagined I would use it like this.
“…No one’s around.”
When I looked around, only the gray darkness covering the park was visible. Centered on this bench, aside from the moaning sounds echoing nearby, there were no signs of people.
After one final check of the surroundings, I reached out toward my sleeping body and touched the soft lips.
“…Huu…”
I slipped my finger between the lips, prying the mouth open. A sticky, wet tongue wrapped around Luna’s finger.
Seeing it through someone else’s eyes was quite… No, why was I getting aroused by my own body?
I snapped out of it and pushed the small plug into my opened mouth.
“Mmm, chu… Ngh… Bwe…”
After swirling the anal plug around inside Isabelle’s—my—mouth and pulling it out, the plug was now coated in a sticky saliva lotion unlike normal human saliva, radiating heat.
“…I couldn’t prepare any lotion, Luna. I’m sorry, but please make do with my saliva.”
Luna’s anus was still undeveloped. I had prepared a beginner-friendly one out of consideration for her, but since there was a chance I could injure this body if I wasn’t careful, I moved with caution.
Just in case, I moved behind the shadow of the bench and placed my hand on the zipper of the pants…
‘N-no…! Doing something like this outside…!!’
As expected, Luna’s soul resisted. But—
It’ll feel good. Even better than yesterday.
‘Better than… yesterday? Ah…♡ But, the Lord…’
The Lord? What did He ever say to you? Nothing, right? And even if you commit a sin, doesn’t He forgive you?
So let’s do it today too. Then tomorrow morning you can pray and repent♡
‘……Yes, that’s right… You’re correct… The Lord forgives all sins… So… just today, just one more day… Even being defiled by carnal desire… He will surely forgive it…♡’
Ziiiip─
My hand moved smoothly. The pants’ zipper came down.
Luna could no longer resist the whispers of ‘filth’ that had mixed into part of her soul. Because that filth was now a part of her too.
The moment I had infiltrated her, Luna’s corruption had already been decided.
Because the ‘curiosity’ I had taught her had given birth to another soul inside her—one that craved that curiosity and pleasure.
All I had to do while possessing her was give that still-weak ‘curiosity’ the right to speak. After that, Luna’s soul, gradually devoured by curiosity, would corrupt itself.
“…Ngh… O-outside… showing such a filthy sight…♡”
I pulled my pants down only to my knees and slightly lowered my panties, exposing only my anus. The cold air touching my buttocks and hole felt completely different from indoors.
Goosebumps prickled all over. The tension of possibly being seen by someone sent a shiver down my spine.
“Haa… Haa…♡”
I breathed roughly, understanding the feelings of the man and woman entwined in the grass.
Instead of the beginner plug, I licked my index finger and brought it to my anus. I tickled the entrance teasingly, and the moment I felt it loosen slightly…!
Schlup─!
“Aah…”
The foreign sensation invading my ass again felt far too strange. The sense of immorality—having something enter a place that wasn’t meant for a cock, developing it like a pussy—blew away all reason.
I wriggled the finger buried in my anus, slowly exploring deeper inside. Just a little more, just a little wider…
Squelch…
“Ngh, haa…!♡”
My finger, wet with sticky intestinal fluid, felt cool as it touched the outside air. The anus had opened to the width of the index finger that had been inside it. At this point, it should definitely go in…♡
I brought the plug, glistening wet and shiny with Isabelle’s—my—saliva, toward my ass.
I pressed the blunt tip against the slightly opened anus and applied a bit of force. An incredible pressure bore down on me.
Even though it was for beginners, it seemed a little too much for Luna’s completely untouched body… In that case, something softer first…
“…Aha, that’s right. You were here…”
“….Suu…”
My sleeping body. An empty shell whose soul had left it. But if I exerted my influence the way Master had done…
“Ugh, ah…”
With faint breathing and moans, the body of Isabelle rose like a zombie, staggering. It looked at me with empty eyes.
I licked my lips with my tongue, following the raised corners of my mouth, then leaned against the bench and pushed my ass toward Isabelle.
Grabbing both cheeks with my hands, I spread the soft, plump flesh wide apart─
“I’m sorry, Isabelle. Please lick it…♡ I can’t hold back anymore…”
I painted another layer of filth onto Luna’s soul as I gave the command to my own body.
“…Aah… Nnghweee…”
Isabelle approached the spread ass and thudded down onto her knees. Then came the hot breath against my anus, followed by my own body extending the Saintess’s snake-like tongue.
The soft, squishy tip of that tongue pressed against Luna’s anus and slowly—very slowly—pushed inside.
“Schluuuup… Nnghup… Haa…”
“Nghooock?! Ah, hick…!”
Mucous membrane brushing against mucous membrane inside my ass. The soft tongue reached deep inside in one go.
Wait, what is this… My vision flashed, huh? Something’s wrong, it’s too sensitive… I’m going to— wait a se─
“Hoooock?! Ah, heaa…? Ah, gah…?!”
I lost control over my own body. The words to stop wouldn’t come out. The bumpy, wriggling tongue like a snake was moving inside my ass─
“Ah.”
Splatter─
Yellow liquid began to fall onto the grass. Incontinence.
My mind went completely white from how good it felt. This kind of thing… This was my first time…
‘…I learned one more thing…♡’
