The Disciple's Secret Obsession
Iris... Master...
024.
I returned to my room and locked the door behind me.
Only after the click of the lock sealed me completely from the outside world did the breath I'd been holding finally burst free. I shrugged off my outer robe without care and reached straight for the deepest corner of my wardrobe.
From a secret crevice that only I knew about, I pulled out Master's underwear—the one I'd hidden there.
"Ah..."
His rich, masculine scent still clung to it, completely intact.
"Hngh—"
The moment that thick, wild male aroma pierced my brain, a twisting heat bloomed low in my belly.
I closed my eyes and stuffed the fabric into my mouth, sucking on it greedily.
"Mmph... mmmh..."
Master's lingering taste filled my entire mouth. I climbed onto the bed, spread my legs, and slipped a hand beneath my panties. Then I began to rub myself carefully.
"Haa... ngh... haa..."

It wasn't enough.
To quench the thirst burning inside me, I reached for the sword Master had once bestowed upon me—my other self, an extension of my very being.
I pressed the hard, cold hilt of the blade against my underwear. The icy metal against my scorching panties sent shivers racing across my skin.
I pushed it harder, grinding myself against it.
"Hngh... ahh!"
The stimulation bleeding through the thin fabric turned my mind white. I pictured the fierce rhythm of Master's hips and the massive size I'd secretly spied on through the window earlier. My hand moved the hilt even more roughly, driving myself toward the edge.
"Haah... mmm! ...Nngh!"
The underwear in my mouth felt like Master claiming me. The sword hilt in my hand became his enormous cock, thrusting deep inside me. The illusion was so vivid it stole my breath.
Master... Master's scent... Master... Please, use me...
In my head, the violent scene I'd witnessed through the window played on an endless loop.
What if it had been me beneath him? What if Master had pinned me down roughly, covering my mouth with his hand?
"Haaah... ah... haa! Hngh... ahh...!"
I bucked my hips, pressing the hilt even deeper. My vision flickered white. The cloth in my mouth was already soaked and ruined with my saliva.
"Master, Master...! Ah, aaaaaah!"
The climax finally crashed over me, sending electric jolts through every limb.
Panting harshly, I clutched the sword Master had given me tightly to my chest and stared blankly at the empty ceiling.
I wasn't sure I'd be able to look him in the eye tomorrow.

The next morning.
I washed away every trace of the previous night with cold water and stood before the door to Master's second-floor bedroom, once again the picture of a neat, disciplined disciple.
"Master, it's morning."
I knocked, but there was no answer. I carefully turned the handle, only to find it firmly locked. Master never locked his door.
Curious, I spread my mana sense through the room. Faint but unmistakable, I detected two presences tangled together inside.
I pressed my ear against the door, but it was eerily silent. Not even the sound of breathing leaked through. The room had been perfectly soundproofed—clearly using magic or an artifact to erase every noise within.
Don't tell me... they're at it since morning...?
As Master's disciple, I should have quietly turned away. But the knowledge that every sound had been completely blocked only made my lower belly throb with heat.
Checking on Master's condition is also part of a disciple's duty.
Muttering that ridiculous excuse to myself, I returned to my own room.
Just like the night before, I erased my presence completely, slipped out onto my balcony, and stealthily crossed over to Master's once again.
Lucky me.
The tiny gap I'd left in the curtains yesterday was still there. Holding my breath, I pressed my eye to the narrow opening.
I couldn't hear anything from inside, but the first thing I saw was Master's broad back as he lay on his side facing the window.
And then the woman's legs.
That alone was enough to understand the situation.
Every time Master's hips moved back and forth, the woman's legs stretched straight before curling again. Her toes curled tightly in unmistakable pleasure, the sight utterly obscene.
The bed rocked with a steady rhythm. Thanks to the magic, no sound reached me, but the visual alone made it crystal clear they were in the middle of sex.
Before long, Master's back muscles tensed and his movements stopped.
A moment later, he rolled over. The woman beneath him crawled between his legs and began lovingly cleaning his cock with her mouth—the very cock that had just been ravaging her.
The devoted, utterly lewd sight held me completely captive. I couldn't look away.
When the two of them finally rose from the bed, I hurriedly retreated to my own room.
Even after draining Master's seed all night, she still wags her tail at him first thing in the morning.
My teeth ground together.
Seducing my Master like that—this vulgar, lewd woman. I cursed Marina viciously in my mind, yet my own body burned far hotter than it had the night before.
That country bumpkin widow had closed the distance I hadn't been able to bridge for so long in a single breath. The overwhelming sense of defeat mixed with my maddening craving for Master paralyzed my reason.
"Haa... haa... Master..."
I roughly yanked open the buttons of my neatly pressed uniform pants. Then I sat on the edge of the bed and pressed my already soaking lower half firmly against the sharp corner of the mattress.
"Hngh... ahh... haaang... Master!"
I ground myself against the hard edge, rolling my hips obscenely. When I closed my eyes, the image of Master's broad back and the pale legs writhing beneath him burned behind my eyelids like an afterimage.
I'm so much more lewd than that slut... Hnngh!
Moans soaked in jealousy and pleasure filled the empty room. The morning of the disciple who had always pretended to be proper and disciplined was crumbling apart in blind lust for her Master.

After finishing breakfast, I headed to the first training ground with Marina Nuna, where the younger children were training.
Iris followed quietly behind us.
"Iris, it's fine inside the garden. Go rest or take some personal time."
"I will remain one step behind."
When Iris stubbornly stepped back, I didn't bother arguing further and simply led the way.
"Huh? It's the director!"
"The director's here!"
The little ones swinging wooden swords and covered in dirt spotted me and came running in a swarm. In an instant they were clinging to my waist, cheering. I patted their heads one by one.
The kids really love you. You must be good to them?
Is there any hero who hates children?
Not really, but you just give off that kind of vibe.
"Have you all been well? No one feeling sick?"
"Yes! Director, where did you go this time?"
"Tell us the story about the four-horned demon you left off on last time!"
"Give us piggyback rides!"
"Director, I trained really hard! Watch me!"
To escape the endless barrage of questions from the children surrounding me, I grabbed Marina Nuna's hand and pulled her forward.
Only then did the children's round, curious eyes turn toward her.
"Director, who's this pretty big sister?"
"This is someone who will be living with us in the garden from now on. Um... she's my girlfriend. Everyone, say hello."
Calling her my wife or the lady of the house would probably burden the children, and we weren't married yet, so I chose the simplest word that matched their level.
"Hello, big sister!"
"Hello!"
At the children's loud greeting, Nuna knelt down, crouching to meet their eyes.
"Hi. Nice to meet you. I'm Marina."
At that moment, a small girl toddled over and threw herself into Nuna's arms.
"...You smell nice."
"Hm?"
"It's warm... You smell like... our mom..."
The girl's mumbled words brought a brief silence over the training ground. Soon the other children who had been hesitating rushed forward with sparkling eyes.
"It's true! It really smells just like my mom!"
"Mom's scent!"
In the blink of an eye, Nuna was surrounded by over a dozen children, completely immobilized. She looked up at me in confusion.
But when she remembered that most of the children gathered in the Garden of Salvation were orphans who had lost their parents to demons or monsters, the panic in her eyes softened into gentle warmth.
"There, there. Be careful not to get hurt. Come slowly."
Nuna gently patted the children rubbing their heads against her, hugging each one tightly as they approached, sharing her warmth.
If that auntie becomes their mom, does that make you their dad?
I was ignoring Lia's silly joke when one of the mischievous boys suddenly lifted the hem of Nuna's skirt.
"Ah!"
Startled, Nuna quickly pressed both hands down to smooth her skirt.
But in that brief instant, another child caught a glimpse of her lower body beneath the fluttering fabric and pointed, shouting loudly.
"Huh? Big sister must have hurt her knee! There's a really big bruise!"
That cry sparked an unexpected debate among the little ones.
"No, dummy! That's a bruise from cleaning really hard!"
"Yeah! The maid sisters who clean our rooms said they get bruises on their knees too!"
"But some sisters don't have bruises? And isn't this big sister the director's girlfriend? Why would she be cleaning?"
It was an argument born of pure innocence. The children simply associated the bruise with the hard labor of a maid. The truth, however, was entirely different.
That bruise was a very indecent, obscene mark left from our frantic coupling in the rattling carriage, from kneeling devotedly on the cold terrace floor last night, and again on the bed this morning—all to serve me.
Tsk tsk. How much did you two go at it in the carriage that the bruise still hasn't faded?
At Lia's blunt jab, I cleared my throat loudly and glanced at Nuna.
She, who had been flustered by the children's innocent reasoning, looked up at me with slightly reddened ears.
Our eyes met sharply in the air. Without needing to speak a word, the memories of last night resurfaced. In the middle of the bright, sunlit training ground, a sticky, lewd current flowed between only the two of us.
Oh no, I'm getting hard again...
The moment my cock began reacting to Nuna's gaze—
Huh? Hey, your top disciple is glaring at the auntie.
At Lia's sudden remark, I reflexively turned to look at Iris standing behind me.
"....."
But Iris stood perfectly straight as always, quietly watching the children with her usual expressionless face.
Are you sure you didn't see wrong? She looks the same as usual.
...No. It was definitely a look mixed with jealousy.
