Slave Bitch (Luna)
3 a.m. Screeech. The door creaked open. My eyes snapped wide in the haze of sleep. I definitely locked it...
"Hehe.♡"
A white silhouette appeared in the darkness. Luna, who'd picked the lock with magic. Her body's curves were blatantly on display. She was naked. She crawled quietly onto the bed.
"Sleep well, my master."
"……."
I pretended to be asleep. Waking up would just exhaust me. She curled up beside me and lay down. The elf's smooth skin touched mine. She used my arm as a pillow and quietly closed her eyes. Sniff, sniff. Her relaxed breathing was soothing.
Is she lonely?
500 years of solitude. How lonely must that have been? A faint pang of sympathy hit me. Very faint. I subtly reached out and patted her shoulder. Luna smiled sleepily and burrowed into my arms.
"I love you."
For sleep-talk, it was a pretty clear confession.
==========
Lick.♡ It was wet. My cheek glistened with saliva.

Slurp... ♡
"Mm."
I opened my eyes. My vision was all white. Luna. She loomed over me, diligently licking my cheek like a puppy waking its owner.
"……What the hell are you doing."
"Morning face wash."
"That's gross."
I shoved her face away. Luna stuck out her tongue and grinned mischievously.
"Master's scent is so good. I held back all night wanting to lick you."
"Keep holding back. Forever."
I sat up. My whole body ached. Having an elf cling to me all night, legs draped over mine, felt like sleep paralysis. Out of habit, I glanced in the mirror. I ended up screaming.
"What the fuck is this!!"
On my nape. A vivid mark right where my collarbone met my neck. A bright red bruise. Anyone could tell it was a hickey. And a seriously intense one, sucked hard.
"Oh, that?"
Luna rolled around on the bed, saying it casually.
"I QR-coded it."
"What?"
"Marked it as mine. Reserved."
"Are you insane? This won't come off!"
I tried flipping up my shirt collar to hide it, but no dice. It was too big and too clear.
"Cover it with magic. Now."
"No way."
"Professor."
"No no no! What if the other bitches eye you up? Gotta spread the word you're taken."
Luna pouted her lips.
"And if I don't mark you... I'm anxious. What if master runs away?"
Her eyes were like a junkie's in withdrawal. Arguing more would just hurt me. This woman wasn't a rational being.
"Haa... Just give me a bandage then."
"Don't have any?"
"Painkiller patch or something."
"I never get hurt."
"Hey, master. How about this?"
===================
"I'll cover it with makeup."
Luna rummaged through her vanity drawer. Fancy cosmetics I didn't recognize spilled out.
"Stay still."
She straddled my thighs, slipping her crotch between them. Face-to-face. Her bare skin rubbed against my thigh. Too stimulating for morning.
"Can't you get down and do it?"
"No. Can't get the angle."
Luna grabbed my nape and leaned in. The puff tapped over the bruise.
"Hold still. Can't do it right."
"Hurry up."
Her touch was surprisingly delicate. The red bruise gradually blended into my skin tone and vanished. Whew. Her breath tickled my nape. Itchy.
"Done?"
"No. Finishing touch."
Mwah.
Luna pressed her lips to the spot again. Long and sticky.
"Haa......"
"It's coating. Coating. Saliva seals it."
I checked the mirror in horror. Thankfully, the bruise was gone clean. Just glistening with her spit on top.
"See? Perfect. I'm good at makeup."
"Fine, now get off. We're gonna be late."
I forcibly lifted her and set her on the floor. Her ass felt cool and soft under my fingertips. Luna smacked her lips regretfully.
"Tch. Wanted to rub a bit more."
"……."
My thigh was slick with her juices. This woman was in heat from morning.
=========================
On the way to school. Luna's car, passenger seat. She hummed happily, stroking my thigh nonstop.
"You know this is sexual harassment, right?"
"What? A slave being cute with her master—how's that harassment?"
"Haa... Just focus on driving."
Luna ignored me and kept chattering.
"What for lunch today, master?"
"Cafeteria food."
"Tastes like shit. Let's go out for steak. I know a good place. I'll cut it for you. Or chew it in my mouth and feed you?"
"Please."
I felt like puking.
===============
"Drop me at the back road."
"Why? Let's park at the front gate, link arms, and go in."
"You wanna get us socially crucified? Professor living with student?"
Luna pouted at my glare.
"Boring. Scaredy-cat. Impotent. Old fart. Forty."
"You're the one with no sense."
We compromised and headed behind the humanities building. I bolted from the car.
"Thanks. See you later."
"Wait."
Luna rolled down the window.
"What?"
"Kiss."
"Are you nuts? Everyone'll see."
"Won't? I'll honk. Hoooonk."
She mimed putting her hand on the horn. She'd totally do it.
"Haa."
I checked around. Clear. I quickly shoved my head in and pecked her cheek. Mwah.
"Happy?"
"Other cheek too."
"Just go already!"
I ran to the lecture hall without looking back. Her giggling echoed behind me.
====================
Morning lecture. Luckily not Luna's class. General elective: Understanding Mages. The huge hall was packed. I hunkered in the corner, hat pulled low. Drained. Morning elf service had shredded my mental health.
Gotta nap.
As I slumped on the desk— bzzz. Phone vibrated in my pocket. Text. Sender: [Slave Bitch (Luna)]. Wanted to change the name, but she'd self-destruct if I did.

Insane. I ignored and flipped the phone. Bzzz. Bzzz. Kept vibrating.
Threat level: god-tier. Psycho prof holding her own shame hostage.
Save me, please.
I clutched my head. Then the kids next to me whispered.
"Yo, saw the school forum?"
"What? Demon lord summoned in applied magic lab again?"
"Nah, Professor Luna."
My heart dropped. I perked my ears, pretending to sleep.
"Who'd she beat up?"
"Power trip?"
"Murder?"
"Human experiments?"
Every guess was grim. Total psycho.
"Nah. This morning, dropped off some guy from her car."
"Boyfriend?"
"Dunno. But they say he kissed her goodbye when he got out."
Fucked. Someone saw. Thought back road was safe.
"Damn. Who's the lunatic dating that witch?"
"Sugar baby, probs. Guy's nuts too. Money can't be that good."
Spot on. I'm nuts too, matching her. I pulled my hat lower.
Then— the door burst open.
"Excuse me."
Cold voice. Room froze. Luna. Click, click. The prof at the podium bowed in terror.
"Oh, Dean! What brings you here?"
"Quick announcement."
Luna's gaze swept the room. Hawk eyes. Spotted me in the corner. Smirk. Lip curled faintly.

"Is Han Si-hun here?"
All eyes stabbed me. Wanted to die.
"……Yes."
"Come with me. Scholarship interview."
Bullshit. Just bored and wants company. But couldn't refuse. Who knows what she'd do.
Grabbed my bag, stood. Sympathy mixed with pity from classmates. Out in the hall, Luna linked arms.
"Missed you, master."
"Coming to the classroom? Really?!"
"You ghosted my texts."
She mashed my arm into her tits.
"Time for punishment?♡"
She dragged me to the emergency stairs. CCTV blind spot.
"What punishment now."
"Inspection."
Luna yanked my collar. Checked the makeup'd nape.
"Hm. Still covered good."
"You called me out for this?"
"Nah. To reapply."
"Huh?"
Slurp.
Luna sucked my nape without warning. Makeup flavor be damned. Even more obsessively.
"Nngh......!"
Fangs scraped skin. Tingling pain mixed with illicit pleasure up my spine. Her tongue snaked over my skin.
"Haaa...♡"
Finally released. No mirror needed—darker now. Maybe actual bruise.
"Safe now."
Luna sniffed the flesh scent on her lips, blissed out. Eyes half-rolled back.
"Master. Gonna change diaper in lab."
"……."
"Come fill it. Or I'll piss here?"
Total madwoman. And the madder part?
...Not so bad?
My hickey-hot nape throbbed. The pain weirdly arousing. I sighed, took her hand.
"Let's go. I'll fill you."
Can I even graduate?
