The Plaster Crumbles

The springs beneath the sofa creak. Beads of sweat glisten across Minji's body as she sits obediently on my lap, and her now fully exposed nipples tremble with a pitiful intensity.

I roll them between my fingers like a joystick, then give one firm tug...

"......"

Squish. Twitch. Twitch. Fluid leaks from her already darkened jeans, dripping onto the sofa. Minji's body—with her legs spread obscenely before stiffening—shudders through another climax. But she has no mouth to moan with. No nose to breathe through. No eyes to see. The thing orgasming on top of me is nothing more and nothing less than a high-performance sex doll.

"It's definitely fun. And hot as hell. Never heard of a woman who could cum from her nipples alone."

Was she always this sensitive? In the nearly twenty minutes I've spent kneading and toying with them, Minji's body has already hit climax three times. I marvel at a form that long ago outgrew the word sensitive and keep massaging her breasts. Every time my fingers graze the edge of her areola without quite touching the nipple, her shoulders give a tiny shiver. When I press down and twist one like I'm digging into her small chest, her entire body jerks hard. It feels like I've slipped back into childhood, playing with some bizarre, multifunctional toy.

"I'll take my time developing this part later. For now, let's see how the lower half is doing."

Reluctantly I release the breasts that molded so perfectly to my palms, grip Minji's waist, and force her to stand. I give her jean-covered ass a sharp slap, but of course she doesn't react. She doesn't even glance back as she slowly lowers the zipper.

Once her pants are down around her knees, Minji's pure-white ass and even whiter panties come into view.

"Bend over."

"........"

Without a single word of reply, Minji smoothly bends at the waist. The motion reveals what her ass had hidden—her soaked, dripping secret place. I carefully peel aside the fabric clinging to her pussy, sticky with her juices, exposing the mucous membrane that glistens with moisture and the hairs matted with slick. A faint, fishy scent tickles my nose. I reach out and spread her open with both hands.

"...As expected, I still can't really tell just by looking."

Compared to the emerald, jade-like membranes of Hyemi-noona and Yunsol that writhed as if alive, the sight of a normal human woman's up close felt strangely different. So Minji really isn't a Saintess...

Squelch— I slide my middle finger straight inside her. Moist. Appropriately tight. Wasn't she supposed to be a freshman? A year below Yunsol... Could the pussy of someone who was still a student last year really be this loose?

I pull my finger free, stand from the sofa, and adjust my stance. This time I push both middle and ring fingers into her. The vulgar, wet sound of her pussy swallowing them echoes, yet she takes even that without strain. Honestly it feels like three fingers would slide in just as easily...

"....."

Silent, I unzip my pants, pull out my heat-swollen cock, and rest it against Minji's bent-over ass. I line up with her entrance—no foreplay needed—and push inside.

Squelch— An adequately wet hole. No extreme tightness, no standout stimulation. I thrust a couple times, but the unsatisfying feeling makes me pull out again. The sex I remembered was definitely better than this... Have I grown too used to the bodies of the Saintesses?

If I count the times I've slept with Hyemi-noona and Yunsol, it's still only a handful. Even so, their pussies are on a completely different level from normal women. They can move their own vaginal walls, create bumps or tentacles to please a man. Comparing a Saintess to a human woman was meaningless from the start. Of course Minji's hole falls short of the two Saintesses.

But even taking that into account, the fact that this hole is pathetic doesn't change. I genuinely can't understand how that senior Taejun could have fucked this rag while he had Hyemi-noona. Her body's a bit better than average, sure, but that's it. In the end the only thing worth playing with is her nipples...

I move my hand to the jutting nipples that first caught my eye and deliberately pinch them hard.

".............."

Flinch—!

"Whoa..."

Minji's fingers, braced weakly against the table, go rigid and tremble. The muscles in her ass and thighs keep twitching. Juice trickles from her pussy. This really is entertaining... But wait. When I'm pinching her nipples, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I notice how stiff her stomach and legs have become. What if I let go instead?

"............"

Drip, drip, drip... With the strength leaving her legs and belly, the tension in her muscles gone, Minji pisses beneath the sofa. I stare quietly at the droplets falling into the puddle on the floor, lost in thought. This could be useful...

I turn and shove the blanket and bag on the sofa into the corner. After stripping her pants off completely, I sit comfortably on the couch, slap her ass once more, and command her.

"Climb on me. And put it in yourself."

"............."

Minji turns and walks toward me, paying no mind to her reddened ass. She kicks off her soaked jeans, lifts her long legs, and straddles me. Her slender fingers grasp my cock, align it perfectly with her pussy, and—

Squish.

She lowers her hips on her own, taking me inside.

Good. Then now...

Carefully I raise both hands, pinch the plump, protruding ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠nipples, and yank them hard. Her body begins to shake violently. Just as I expected, her stomach and leg muscles lock up. The pussy that I couldn't honestly call good suddenly squeezes far more pleasantly. The stimulation is still lacking, but it's fine.

"Hands behind your head. Move on your own. Don't stop until I cum."

"............"

Obeying, Minji laces both hands behind her head and starts slamming her ass down in that obscene posture. The remaining stimulation is more than covered by the immoral thrill of owning a doll that moves exactly as I wish.

Even though her nipples are being pinched hard enough to look painful from the outside, Minji's body never stops moving. Her insides convulse; it seems she cums lightly with every thrust of her hips. The harder she moves, the more violently her body shakes. Her nipples are stretched taut without me even needing to pull, and the fresh stimulation sends her into another climax.

Trapped in the reins of pleasure, Minji slams her ass against me with increasing ferocity, serving me.

Definitely... This is definitely...

It feels like something is ringing inside my head again... It definitely feels good, but something's off... What the hell am I even doing? I came to the east to rest for a while...

My blurred vision sharpens again.

"...Ugh?!"

What fills my now-clear sight is the face of a pure white plaster statue. More precisely, a face in the middle of becoming something. A crack splits where the mouth should be, revealing a bright red tongue glistening with saliva. Curves appear on the flat surface, forming a nose. Eyebrows and eyes follow the bridge. Lifeless black pupils gaze down at me. Clean hair sprouts from the scalp, flowing down to her shoulders in moments. The skin that had been nothing but white plaster regains color and softness. The unknown shell that had swallowed Minji's head has transformed into Minji's own face.

The woman before me is the same Lee Minji I met in the lounge today—the one who had been begging forgiveness from Hyemi-noona. The ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠slyness hidden behind her cute, rabbit-like appearance, the opportunistic cat-like glint in her eyes... none of it remains.

"...What the hell is this..."

What is happening? Why am I having sex with this woman?

The question dies before it can fully leave my lips.

"Chuuup....."

"Ugh?!"

Minji stares down at me with eyes that somehow convey no gaze at all. She silently grabs both my hands, extends her tongue, and steals my mouth. Her tongue moves inside with steady, practiced strokes. I can't push her away. I don't know what's happening, but she's too strong...

Slap. Slap! The sound of flesh colliding grows louder, faster. Her pussy clamps down far harder than before I regained my senses. The mucous membrane inside has grown unbearably hot and sticky.

"...Kgh...!!"

"..............."

I cum helplessly inside the Dummy Doll that Minji has become. Once my ejaculation ends, she lifts her hips. My limp cock slips free, and the semen that never reached her womb drips onto the floor.

"...Damn it..."

I knew immediately that the mask had done something to me again. The sensation of brakes failing inside my skull, the helplessness of being unable to control myself—I cursed under my breath...

"...Master..."

"......What?"

Minji's short, expressionless voice instantly seized my attention.
