How to Be Loved by an Erosion Witch (9)

"Hngh… Ahh… Teacher… I… I feel weird…."

Jin Se-hee's body was burning up like a fireball. She writhed helplessly in my arms, rubbing and twisting against me. The damp sensation seeped through her loose sleep pants, accompanied by the sweet, hazy scent of her body wafting over me.

I brought my lips close to her ear.

"Nothing weird about it. It's all part of the treatment."

"Tre… atment…?"

"Yeah. Counseling isn't just talk. Releasing built-up stress with your body is a key step too."

I slid my hand down, slipping it inside the elastic waistband of her baggy sleep pants. My palm filled with soft, yielding flesh.

Schlick—

"Eek?! Ah! Ah! It's cold…!"

She jolted in surprise, her hips bucking up. But she didn't resist. If anything, she parted her legs slightly, as if making room for my touch.

No panties. Just bare skin. The flesh of her ass against my palm was unbelievably soft and springy. Hard to believe this was an ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠unmaintained body.

'As expected of a magical girl. Cheat-level figure.'

I slid my fingers lower, finding her flooded secret place.

Squelch… Glorp…

"Haaaang! Ah! Ah! Ah! Teacher! Nngh! Not there… not thereee…!"

"Why not? You're soaking wet."

"It's embarrassing… Ah! It's dirtyyy… Nngoooh!♡"

Despite her words, her entrance twitched, trying to swallow my fingers. Love juices streamed down, slicking her inner thighs.

I flicked the swollen clit with my fingertip.

Glorp! Twang…

"Kyaaah?! Ah! Ah! Ah! Nngh! It stings! Nngoooh! My head… my head's going weird!♡"

Jin Se-hee's head snapped back. Her unfocused eyes wandered the air, drool trickling from her open mouth.

The numbers were skyrocketing. 96%. It was right there.

The higher it climbed, the calmer my own excitement became.

It was coming.

Dark red geometric patterns etched across her pale skin like tattoos. Mana circuit backlash.

The legendary precursor to a magical girl falling into witchhood—the "erosion" phenomenon. My mouth went dry. I started acting flustered to match.

"Ugh… Urgh… Teacher… I'm… so hot… my body's… burning up…!"

"Ma'am, you have to hold on. A seizure like this, why so suddenly…!"

"I… I can't… hold it…!"

Black sparks flew from her body. The room's fluorescent lights flickered, then burst with a pop.

Darkness fell. Only the faint purple poison qi emanating from her body provided dim light.

"Kehuk…!"

A grotesque death rattle escaped Jin Se-hee's lips. Her eyes spun, then rolled back white.

Thud.

Her convulsing body went limp like a puppet with cut strings. Comatose state. The pre-witch transformation coma.

"I… I did it."

My legs nearly gave out. But no time to rest. This was my only shot.

With trembling hands, I picked up the choker from the floor. From my pocket, I pulled out the vial Viper had given me.

Clink.

The lid popped open easily. I dripped a drop of the clear liquid onto the choker's buckle.

Sizzle.

White smoke rose as the leather subtly contracted, activating. All that was left was to collar her.

"Sorry, ma'am. Or… Ms. Jin Se-hee."

I propped up her limp upper body. Her head lolled back powerlessly. No consciousness, but her body radiated intense heat.

I wrapped the choker around her neck.

Click.

The buckle's sound echoed loudly. At that moment, a red magic circle flared on the surface, sinking into her skin.

Success.

I hurriedly backed away. Now, just wait for her to wake.

Vrrr—!

Jin Se-hee's body slowly lifted from the floor. Like zero gravity, she floated into the air.

Her worn hoodie and sleep pants swirled in black particles, burning away to ash.

In their place, inky darkness draped her like a dress. The black mana circuits glowing on her skin sculpted her new form.

A magical girl transformation scene. The polar opposite of the flashy, hopeful spectacles on TV.

Grotesque, sinister, yet irresistibly alluring—a ritual of corruption.

Rumble…

The cramped basement room vibrated with her unleashed mana.

And finally.

The black particles cleared, the murky air settled. The overwhelming mana waves filling the room gradually subsided.

"Haa… Haa…."

The being before me. The frumpy middle-aged woman in the dingy padding just minutes ago was gone.

In her place stood a witch.

"……."

A dress woven from pitch-black darkness. A flowing purple gown hugged her voluptuous curves.

Most shocking was her appearance.

Her taut, wrinkle-free skin had youthened further, like her prime in her early twenties. No—even more seductive and dangerous.

And around her pale neck gleamed the black leather choker I'd fastened, adorned with a heart-shaped gem.

'Success…?'

The choker's red gem pulsed softly. It meant she wasn't out of control—and her witch powers were suppressed.

I approached cautiously.

"A-are you okay, ma'am?"

Her gaze fixed on me at my words.

"Ah…."

Her lips parted.

I tensed for a moment, but witchified Jin Se-hee showed no resentment or contempt. Instead.

Her face bloomed with the brightest, most spine-chillingly tender smile in the world.

"Found you."

Swish.

She glided toward me across the floor.

Her long arms pulled me into a tight embrace.

"Mmph…?!"

A suffocating hug. Her ample breasts smothered my face. Her witch's scent—cool yet electrifyingly lewd—stabbed my nose.

"My baby…."

"Pardon?"

I doubted my ears. What did she just say?

"My good baby… there you are?"

She stroked my head. Like a mother finding her lost child, or a girl reclaiming her most precious doll.

"Ma'am…?"

"Shh… good boy, such a good boy."

She ignored me, just trapping me in her arms, rubbing her cheek against mine, refusing to let go.

'What the hell is this?'

Maternal instinct?

Her corruption desire had shifted from ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠"game addiction" to "Jeong Ji-un."

To her, game characters were things she poured love into, raised, controlled.

'And she neglected her real daughter. It all mixed up, seeing me as her baby?'

I had no idea. But one thing was clear. Her eyes, her desire—fixed solely on me.

"Um, ma'am. Could you let go…."

"Ma'am?"

She pulled back slightly, looking down at me. Her languid, half-lidded eyes curved seductively.

"Call me Mommy."

"……."

"Come on. Say it. Mommy?"

Her finger tapped my lips. Thanks to the choker, her strength was human-level.

'I could resist if I wanted. But….'

Gulp.

Her far lewder form now had my mouth moving on ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠its own.

"Mo… Mommy?"

"That's right, good boy. My baby did so well."

Mwah.

She planted a deep kiss on my forehead. The cold lips sent chills down my spine.

"Hungry? My baby's whining 'cause he's hungry?"

"Y-yeah…."

"Hehe, then time for milkies?"

She sat me on her lap.

"Here, drink up."

Slipping down. She pulled down the off-shoulder dress's bust. Unrealistically massive tits bounced free.

"……!"

Her skin, now rosier and creamier. On the translucent flesh where veins faintly showed, flushed nipples protruded. Far bigger and riper than her magical girl days.

I squeezed my eyes shut and took the pink nub in my mouth.

Nom.

Warm, squishy fullness filled my mouth. The bumpy texture of the nipple on my tongue.

"Hngaaah…♡"

Her immediate reaction burst out.

"Good… so good… my baby…."

Instinctively, I swirled my tongue around the nipple, sucking with my cheeks.

Slurp…

That was the moment.

Whoosh—!

"……?!"

What flowed into my mouth wasn't milk, obviously. More like… an energy mass.

Mana? No. This is….

'Poison qi?'

"Mmph, mmf?!"

I reflexively tried to pull away. But Jin Se-hee pressed my nape harder.

"Where… ah! You going… haaah! Finish it all, my baby…?"

Gulp.

I swallowed. No, I had to. Once tainted with poison qi, it had to be dealt with.

The hot lump slid down my throat. The moment it hit my stomach, scorching flames erupted inside.

'Urgh, witches are made of poison qi all over?'

At least I could store some now. A normal person would've been obliterated.

"Puaah…!"

The nipple slipped free, a sticky thread of saliva stretching long.

"Oh my?"

Jin Se-hee blinked wide, looking down at me. Her face was pure innocent curiosity.

"All done already? Mommy's still got plenty of milk…."

She cupped her massive breasts, lifting them. They jiggled heavily, tempting me.

"Gotta drink more. Gotta grow big and strong, right?"

Her hands reached for my head again. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠Terror. Any more and I'd cross the River Jordan for real.

I racked my brain desperately.

Just saying no might upset her. Needed to redirect her attention.

"M-Mommy…."

I squeezed out the most pitiful, pathetic voice.

"Yes? What's wrong, baby?"

"It h-hurts…."

I scrunched my brows and whimpered. Worry flooded her face instantly.

"Hurts? Where? Tummy ache? Did you get a bellyache?"

"N-no… not there…."

I slid my hand lower. Pointed to my crotch, where my pants strained, bulging to burst.

"Here… it hurts so much…."

Not a lie.

My rock-hard cock throbbed, threatening to rip through the fabric.

Jin Se-hee's eyes followed my finger downward.

"Oh my…."

Her eyes widened. The obvious tent in my jeans. Unmistakable physiological reaction.

"Oh dear… my baby's pee-pee swelled up 'cause he needs to go potty? Mommy's sorry. I was so focused on feeding you, I didn't notice my baby's pee-pee hurting…."

Her hand approached my waist. Cool, soft fingers touched my belt buckle.

Clink… Click-clack.

"Let Mommy see."

No hesitation as she unzipped. She tugged down my pants and drawers.

Shh… My repressed member sprang free. Veins bulging on the red, massive shaft at full erection. Hotter than usual from the poison qi.

"Oh goodness…."

She stared, entranced. Gone was the "swollen from needing to pee" act.

Her pupils narrowed vertically, gleaming with a witch's greedy hunger.

"My baby… so sturdy… Mommy's never seen one this healthy…."

She reached out, lightly touching the glans.

"This is what hurts, right? All swollen and puffy… must've been tough. Mommy'll make it better."
