Branded Ecstasy and the Scanner's Trap
[Master Exclusive]
"Wh-what... Hurry up and move..."
"How many centimeters deep have I gone in right now?"
"Huh? H-how am I supposed to..."
"You're a 0-grade Archmage, aren't you? Measure it. With your hand—where you're pressing down, right there."
I slowly pulled out, then let just the tip touch her entrance again. Teasing her.
"If you're wrong, class ends here for today?"
"N-no! Don't pull out!"
Luna freaked out and wrapped her legs around my waist, clamping tight.
"Then guess right."
"W-wait a sec! Don't move—let me feel it!"
Luna rolled her wine-red eyes, focusing hard. The great archmage mobilizing her numb uterus and vaginal muscles, still stinging from the slaps, to gauge the size and depth.
"Hmm... The glans... it's right up against where you punched me with your fist earlier..."
Her inner walls rippled and writhed like waves, probing like a living creature—measuring length, circumference.
"17... no, 18.5 cm!"
"Wrong. Incorrect."
"Liar! It was right there!"
"You got excited when you were slapping teacher's belly, so it got bigger."
I grinned mischievously, pressing down on her lower abdomen with my fist while slamming my hips forward hard.
Squish! Slap!

"Aaagh! Guh! 19! No, 20! I don't know! It's just so full! Completely stuffed!♡♡♡"
"You're lacking in studies. No teacher qualifications."
"I don't care! I quit being a teacher! Just make me your meat toilet! Use me as a meat toilet every day, punching my belly!"
Luna gnawed at my shoulder, howling. A face defeated by pleasure. Her belly flushed red from fist marks, the 'Meat Toilet' tattoo on her ass glistening with sweat.
"Cum in me... student... inject some disciplinary semen into teacher's bruised womb..."
"As you wish."
I gripped her reddened lower belly with both hands. Pressing to force open her womb's entrance, I ramped up for the final sprint. To the deepest unknown depths she'd given up measuring. Pouring everything I had into her.
Spurt-spurt-spuuuurt-!
"Kiiiiieeeeek-!!!!♡♡♡"
She screeched grotesquely, clawing at the blackboard. Her womb gulped down my seed greedily, convulsing.
"Haa... haa..."
A good while later, we collapsed tangled on the living room floor. Luna, draped only in her gown, eyes rolled back, tongue lolling out. Her bruised lower belly heaved with ragged breaths.
"Pass...?" she mumbled.
"Did I... pass, disciple...?"
"...Conditional pass."
I chuckled, sitting up. Murky fluids leaked from between Luna's legs, soaking the floor.
"Review thoroughly until the next exam. Or else."
I jabbed her reddened belly with my foot.
"Oguk?!?!♡♡"
With a lewd squelch, fluids squirted from between her legs.
"I'll fill you till your belly's really bloated next time."
"Yessh... Master...♡♡"
Luna crawled across the floor, kissing the top of my foot. The [Meat Toilet] tattoo looked especially vivid.
"Auuu... My back..."
Fresh from the shower, Luna slithered onto the sofa. Wearing just one of my baggy t-shirts—the so-called 'boyfriend shirt' look. Every time she moved, the hem swished, flashing the pale tattoo on her ass.
"You gonna dry your hair? You'll catch a cold."
"Too bothersome. Master dry it for me."
Luna plopped down between my legs, leaning back against me, draping her wet silver hair over my knees. Full spoiled-brat mode.
"Haa... You really take a lot of work."
I grumbled but had already grabbed a towel. Gently patting the moisture, Luna closed her eyes with a contented grrr.
"Feels good..."
"What does?"
"Everything. Warm, languid, belly full."
Luna stroked her lower abdomen lightly. The spot I'd punched red and bruised earlier. But she rubbed the bruise lovingly, like a pregnant woman cradling her baby.
"Master filled me up so much. It's heavy.♡"
"Don't say stuff like that. Sounds perverted."
"Why? Scholars speak in 'facts,' right?"
I switched on the hairdryer. Whiiiir—. Warm air tousled her silver strands. Thanks to magic maintenance, her hair was silky as satin. Just touching it lifted my mood.
"Si-hun."
"Yeah."
"I want ice cream."
"Cold stuff'll upset your stomach. Your belly's already bruised."
"My insides are hot. Need to cool them."
Her retorts flowed effortlessly. I roughly dried her hair and headed to the fridge. Strawberry flavor. Popped the lid and brought it over; Luna gaped her mouth like a baby bird.
"Ahh—."
"No hands?"
"Not even strength to wiggle my fingers. Used it all clinging to the blackboard earlier."
What excuses. I scooped ice cream onto a spoon and fed her.
"Cold and sweet...♡"
Luna puffed her cheeks adorably, munching. Pink cream smeared her lips.
"Eat without getting it everywhere."
"Wipe it."
"Here's tissue."
"No. With your tongue."
Luna thrust her face toward me. Eyes full of mischief, dripping with affection.
"Hurry. It's melting."
"Haa..."
I leaned in helplessly, licking the sweet cream from her lips. Luna giggled, wrapping her arms around my neck. Smack. A light kiss. The beastly passion gone; now she was just a girl in love.
"Tasty?"
"Very."
"Me too?"
"Mine was a bit fishy, though."
"Hey!!"
Luna playfully thumped my chest. We tumbled on the sofa, laughing.
"But Si-hun."
"Yeah."
"My throat's dry. Guess I screamed too much."
Luna fiddled with her neck. Her voice was definitely hoarse.
"Told you not to scream like that. Had me worried someone'd call the cops."
"But... getting fucked while my belly's punched... first time."
She burrowed deeper into my arms.
"It hurt so much but felt so good my brain went white. Am I really a crazy bitch?"
"Took you long enough."
"Yeah. Crazy bitch just for Si-hun."
Luna took my hand, rubbing it on her cheek. Warm. A 500-year-old archmage. The cold Frost Witch. But in my arms now was just a lonely little woman craving love.
"Hey, Master."
"What."
"Where next for the brand?"
"......"
Moment ruined in three seconds.
"Boobs? Inner thigh? Big '[Master Exclusive]' there."
"Please."
"Or forehead? Real slave style."
"Just sleep!"
I shoved the rest of the ice cream in her mouth. Luna went "Mmf mmf!" but smiled blissfully, eyes crinkling. Sunset glowed outside. Peaceful enough. Good.
"Not erasing it."
Morning squabble in the dressing room. Luna bared her ass to the full-length mirror, twisting this way and that. The vivid tattoo on one cheek: [Meat Toilet]. Rushed in excitement, the letters were crooked.
"Professor. Please. You know there's a full staff security scan at the main building today."
"I know."
Luna nonchalantly flexed her glutes. The burn scar twitched.
"That nutjob professor from Oxford Magic Academy terrorizing with artifacts."
"Yeah. Our school's in uproar too. Scanning professors for weird stuff—if they find it, what then?"
"That's why leave it. This brand."
Luna traced the stroke of the 'Meat' character with her finger. A perverted smile savoring the sting.
"Makes my womb quiver every time I see it in the mirror. Proof Master burned my flesh.♡"
"Not the time for romance. Use healing magic at least."
"No! Precious! When it scabs, I'll peel and keep it!"
No reasoning. I sighed, adjusting my clothes.
"Do what you want. But if caught, I know nothing."
"Don't worry. Who am I? 0-grade Archmage. Illusion magic covers it perfectly."
Luna smirked confidently, dressing. Her usual prim women's suit. Perfect department head look. But I knew: nothing under the skirt. 'Wounds hurt if they rub' excuse, but really just pervy.
Main building lobby. Usually quiet, now chaos. Massive security gate at central entrance for terror prevention.
Murmurs. Professors and staff grumbled in line.
"Me, a professor here, and they wanna body-search?"
"Please cooperate. President's orders."
Guards sweated, managing the crowd. By the gate, arms crossed, smug: Professor Ludel.
"Oh? Department Head Adelheit? Surprisingly early?"
Ludel approached with a sly smile. Dress emphasizing her chest today. ...Still a shorty though.
"Professor Ludel? Why are you here?"
"I developed this new security gate. Well, the 'Magic Resonance Scanner' precisely."
Ludel patted the gate. Silver frame etched with complex magic circles.
"Performance is amazing. Doesn't just catch simple artifacts."
"?"
"We mages use our own 'bodies' as artifacts sometimes? So it detects 'traces' too."
Ludel narrowed her eyes.
"Magic alterations within the last 24 hours. Visualizes the residual mana form too."
She thrust out her chest (padded) and laughed vapidly.
"Ho ho ho!"
Luna's face stiffened. Magic alteration traces. Visualized. If she passes... the 'Meat Toilet' brand blasts on the screen huge. Illusion won't work—detected as another trace, stripped away.
"What's wrong? You look pale?"
Ludel eyed Luna. Dwarf intuition kicking in.
"Hiding something on your body?"
"Of course not. Just tired."
Luna forced calm. But her hand on my arm trembled like a leaf.
[Master.]
'I'm listening.'
[What do we do? Illusion magic won't work!]
'Aren't you a way better mage than the professor? Can't fool it?'
[Can't! That midget shitbag dwarf's artifact-making skills are insane. If I go through...]
Gulp. Dry swallow.
[Everyone'll see what's written on my body...]
