ASMR Audit: The Department Head's Leaky Thrill
[She's peeing! My slave bitch's filthy cunt is gushing piss! ♡♡]
"Nngh! Ahhn! ♡ Right there! It feels so good!"
Autopilot mode. The smooth ride was a joke. The car was thick with steamy heat. Luna leaned back against the seat, her legs splayed wide in embarrassment. Her skirt had been hiked up to her waist ages ago. My fingers slipped in and out between the bands of her freshly changed adult diaper.
"Master's fingers are so warm."
Squelch, squelch♡. The sticky sounds echoed through the car. The inside of the diaper was already soaked through.
"Stop peeing already. You just put on a new one and it's drenched."
"I can't help it. Master's touching me, so it keeps leaking out."
"You told me to touch you, Professor."
"Even sooo... Ngh?! ♡"
Luna hung off my shoulder with hazy eyes. Her pussy clenched around my fingers like it was spasming.
"We're almost home. Time to pull out."
"No. Keep them in until we park. In the elevator too—no, can't you just leave them in forever?"
"CCTV would catch it all. Want to make the news?"
"Don't care. Headline would be... mm, 'The Department Head's Fall'... Hehe, sounds so hot. ♡"
No response to that. I forcibly pulled my hand out and wiped it with a wet wipe. Luna smacked her lips regretfully, fiddling with her damp diaper.
A few days later. Department Head's Office.
"Put this in your ear."
What Luna handed me was a small earpiece-shaped magic artifact. A tiny gem was embedded in the center.
"What's this? An earphone?"
"'Voice Transmission Artifact.'"
"Why?"
"Today's the Education Ministry inspection."
Oh, right. The quarterly magic education ministry audit. The notoriously strict inspectors checked the school's budget and facilities. As department head, Luna had to escort them personally—it was a big deal.
"So?"
"The inspectors are old fogeys. Gotta give them boring explanations all day."
"What does that have to do with this?"
Luna grinned. She lifted her skirt just a peek. She was wearing the 'ultra-absorbent' diaper we'd bought at the mart yesterday. It crinkled loudly with every step.
"I'll get bored. So listen to my sounds, Master."
"What sounds?"
"My pissing sounds."
"......"
"This thing's super sensitive. You'll hear everything from my urethra opening to the diaper soaking up—full ASMR."
"You're insane?!"
"Don't wear it, and I'll strip and piss right in front of the inspectors?"
Threats were daily routine. I sighed deeply and popped the earpiece into my left ear.
Tzzzt-.
Luna's voice whispered right in my ear, vivid as if she were breathing on me.
"Loud and clear."
"Good. Your slave Luna's doing ASMR for you today—enjoy it♡."
Knock knock.
"Department Head, the inspectors have arrived."
The assistant's voice. Luna's expression flipped instantly. The lewd bitch's smile vanished, replaced by the icy dignity of a 500-year-old 0-grade Archmage.
"Tell them to come in."
She winked at me. Her lips mouthed, 'Listen well.'.
"Pleased to meet you, Adelheit Department Head."
"Welcome, Inspector Han Mi-kyung. You must be tired from the trip."
The inspector was a stern middle-aged female mage. She peered over her glasses, scanning the lab.
"I hear the magic department's research results this year are impressive. Especially in mana flow control using small magic stones."
"You're too kind. Allow me to show you around."

Luna led the way. Click-clack, click-clack. Her heels echoed down the hall. I followed with the briefcase as her assistant—picture-perfect on the surface. Haughty department head and her diligent aide.
But my left ear was in a whole other world.
The diaper's rubbing assaulted my eardrums with every step. Too damn good—the fabric brushing, thighs slapping together, all raw and unfiltered.
"This is the Third Magic Engineering Lab."
Luna gestured gracefully.
"We're researching 'household spirits' ready for commercialization."
"Ho, intriguing. Is the budget execution transparent?"
"Of course."
Luna's explanations flowed flawlessly. But I could see it—the subtle quiver in her butt as she clasped her hands behind her back.
While the inspector reviewed documents, Luna wiggled her hips—a signal just for me.
'Hold it. We just started.' I warned with my eyes.
But Luna blatantly clenched and released her urethra over and over.
"......Hup!"
A trickle leaked through the earpiece. Just a taste—a teasing dribble.
"Department Head? Something wrong?"
"N-no. My throat's just dry."
Luna brushed it off with a calm smile. But her inner thoughts broadcast live in my ear.
This woman was thriving on the thrill. The solemn audit had turned into her playground.
The crisis hit at the outdoor training grounds. The inspector scrutinized a large barrier stone in the corner.
"Barrier sustainment is down 3% from last year. Slacking on maintenance?"
"Within measurement error margins. I'll demonstrate personally."
Luna stepped up to the stone, raising one hand. Mana swirled around her as she focused.
Problem: Using mana raises abdominal pressure.
'You're demonstrating! Hold for one minute!'
Her legs shook visibly. With the inspector and other professors watching—no room for error. One slip, and the century's greatest mage becomes a bedwetter.
"Department Head? Let's begin."
The inspector's prompt. Luna bit her lip.
"......Haat!"
With a kiai, light burst from her fingertips. The barrier stone hummed to life.
At the same moment—
My left ear went numb from the roar of liquid.
"Impressive output!"
The inspector marveled—at the light from Luna's hand. But to me, it meant something else.

Luna poured mana—and piss—in manic ecstasy. Her skirt noticeably bulged. Sssshhh-. The diaper's absorbent layer slurping it up. Warmth trickling down her thighs. Every bit pure ASMR ravaging my eardrums, just like she said.
"Excellent! As expected of the federation's first 0-grade Archmage!"
The inspector clapped. Demo over. Luna lowered her staff.
Wobble. She staggered, off-balance.
"Department Head!"
I rushed to support her. Her body burned like fire. The butt under my hand was soggy as a waterlogged sponge.
Yup. She pissed.
"Are you alright?"
The inspector approached worriedly.
"M-mana... consumption... was... bigger than... nngh♡ expected."
Luna panted, clutching my clothes. Her eyes glazed over. Total exhaustion to anyone watching.
But I knew. This was post-orgasm sage mode, not mana drain.
"She needs a break. Assistant, help her."
"Yes, ma'am."
I half-carried Luna toward the main building. Behind us, the inspector tsked admiringly.
"Such passion, not sparing her body even as department head. Admirable."
Admirable my ass. She went limp from pissing her diaper.
Empty lecture hall. I sat Luna on a desk.
"Are you crazy? Pissing it all out there?"
"Haa... haa... Don't know... Felt too good..."
Luna murmured blankly at the ceiling.
"When that old hag clapped... my hole was gushing piss..."
Technically, you're the hag-professor here.
"You thought something dirty, didn't you?"
"N-no!"
"Hmmm-♡?"
She snorted softly, pulling my hand to her skirt.
"Feel it. About to burst, right?"
I knew without touching. The diaper was swollen to its limit, heavy with piss.
"Change me, Master."
"Here? Go to the bathroom."
"Can't walk. Too heavy. And it sloshes—might spill."
Luna spread her legs in an M. Hiking her skirt revealed the bloated diaper. Leaks had already soaked her thighs. One step, and it'd drip everywhere.
"Hurry. Next inspection area's soon."
"Haa......"
I locked the door. Drew the curtains. Pulled a fresh diaper and wipes from my bag.
Riiip-.Plop.
Undoing the tapes dropped the sodden mass. Pungent piss stench mixed with sweet female musk hit hard.
"Haaah... So refreshing..."
Luna shivered in relief. I handled cleanup like a pro. Wiped the stink away.
"Haaah... ♡♡"
Tapped gently to avoid hurting sensitive spots—wrist snap to dab moisture. Powdered up, fitted the new one.
"Si-hun."
"Yeah."
"Praise me."
"For what? What'd you do right?"
Luna hugged my neck. Soft breasts pressed my face.
"Didn't get caught. Nailed it."
"At the cost of ten years off my life."
"Hehe. Love you."
Mwah. Light kiss on my lips.
She plucked the artifact earpiece from my ear.
"Won't need this anymore."
"Why? Gonna switch to other sounds?"
"Nah. Bladder’s empty now."
Luna whispered seductively in my ear.
"Tonight, different sounds."
"......?"
"Not pissing. Moaning while getting fucked. Wanna hear?"
She guided my hand to her breast. Heart pounding.
"Finish the audit smooth, and I'll really let you."
No joke this time. Her eyes dripped with sticky lust.
"So do your best? Master♡."
She hopped off the desk briskly. I stood frozen, holding the warm, heavy 'used' diaper.
'She's serious...?'
Graduation be damned. I was on the brink of becoming a true grad student—balls-deep.
