The Doll's Trigger
“Hmm, I think I get it now.”
While she was screaming in terror and trying to crawl away from me, I shoved my fingers into Seo-rin’s ass. Her eyes went blank, and she simply stared into empty space like a broken doll. Watching that, I finally understood what Chae-yun had done.
To confirm, I repeated the motion several times. When I pulled my fingers out, a thick, sticky strand of fluid stretched between them. At the same moment, light returned to Seo-rin’s eyes.
“...Hngh?! W-what just...! Hyah?!♡”
The moment I pushed my fingers back into the crack in her consciousness, she instantly reverted to that lifeless doll state. I was certain now. Chae-yun had inserted that massive plug, and either removing it or being alone with me had satisfied some condition that activated a new suggestion.
A suggestion that turned her into a doll the moment something foreign entered her ass. I wasn’t one to talk, but it was pretty damn twisted.
“...Still, we can’t stay like this forever.”
I glanced between my own situation and hers. She lay frozen in the exact position she had been thrashing in, while I sat with my fingers buried in her ass. Pulling them out would probably make her loud again. Should I just carry her to the bed like this? My back was already starting to ache from the awkward posture, and I couldn’t exactly lift her with my right hand stuck inside her.
While I was debating, my eyes landed on something nearby. I reached over and grabbed it—the huge plug that had been sealing her ass earlier. This would work perfectly.
I yanked my fingers out and shoved the plug back in before she could regain her senses. I felt stupid for ever worrying whether it would fit. Her stretched hole swallowed the massive thing with obscene ease.
“Uhot?!♡”
She let out a single moan as a flicker of awareness returned, then immediately became a doll again. I swallowed a laugh at the ridiculous sight and was about to lift her when—
“...Plug reinsertion confirmed...♡ Per the Mistress’s orders, I will now explain my current state to Master♡”
The moment I touched her to pick her up, Seo-rin’s eyes remained dead, but her face lit up with a bright, lewd smile. She bowed deeply and greeted me.
I was stunned again. Chae-yun had prepared quite a lot.
“Greetings, Master♡ The Mistress has permitted me to harbor emotions toward you, so I may speak freely♡ Thanks to Master’s merciful hands-on training, I have become this... hngh...♡ Ahng♡ A little...!♡ A perverted body that climaxes just from having its ass pounded♡”
Still speaking in that cheerful, obscene tone, Seo-rin grabbed the plug herself and began fucking her own ass with it, pistoning it in and out while displaying both absolute loyalty and utter depravity.
“The Mistress praised me, saying, ‘As expected of the first toy I ever made,’ and gave me an opportunity♡”
“...Opportunity? What opportunity?”
Without realizing it, I had sat down on the bed to enjoy her perverted performance. I asked the question.
“The chance to become Master’s personal anal onahole♡ Ahh... How merciful...♡”
Her voice trembled with emotion as she uttered words that would have made the old Seo-rin faint on the spot. I pressed her again.
“...What do you mean by that?”
“If the plug is removed again, I will foolishly revert to my original self who cannot comprehend Master’s mercy♡ Then a new suggestion will be added: instead of simply becoming a doll when something enters my ass, the pleasure accumulated while dollified will explode all at once upon returning to normal♡ If my original self succumbs to that pleasure, this personality that absolutely obeys Master will overwrite her♡”
“...Interesting.”
I was genuinely impressed by the event Chae-yun had prepared. This looked like the most fun we’d had yet. Seo-rin noticed my hungry expression and spoke in an excited voice.
“This information will also be engraved into my original self’s memories♡ I hope Master will enjoy watching my pathetic attempts to resist even though I know that once Master’s cock enters my anal pussy, my corruption is guaranteed♡ Well then...♡ Hngh?!♡”
With those final words, she pulled the plug out herself and collapsed to the floor, twitching. Light had returned to her eyes.
“...Ahe♡ Hnghaa♡ W-what...♡ This memory?!♡”
Unable to move properly, she braced herself with one hand on the floor and the other on her head, slowly pushing herself up. For a moment she stared at the ground, seemingly sorting through her thoughts.
“...Ah, ah...?!”
Finally, she raised her head and met my eyes.
————————————
‘If you succumb to the pleasure Master gives you, you will disappear, and you will live a life where serving Master is your only joy.’
“...Ah, ah...?!”
When I opened my eyes, I saw an unfamiliar room. I was naked on the floor, and a man was sitting on the bed, looking down at me with an unpleasant expression. Startled, I shrank back, and incomprehensible words began swirling in my head.
Master? Corruption? Slave? My mind couldn’t process what any of it meant. But for some reason, I felt an overwhelming terror that those words weren’t lies—that if I tried to run, I would truly disappear.
Disappear? I would disappear? And become... a slave who exists only for that man?
Trembling violently, I forced myself to look at him.
“I-I don’t want this...”
My mouth moved on its own.
“I don’t want this!!”
And then my body moved. I had to run. I had to get away. I started sprinting toward the door that looked like the exit, desperate to escape the man. Even though I was completely naked, getting out of this room mattered more than whatever shame awaited me outside.
I didn’t want to die here. Not by that man’s hands!
I reached for the doorknob. Just a little more...!
“If you scream like that, people will get the wrong idea.”
The man snatched my hand off the knob and yanked me around. His face finally came into view. I recognized it from somewhere.
“...Huh?! You’re definitely...!!”
Where? Where had I seen him? My mind raced. It didn’t take long to place the face.
Same university, same department, same year. The guy who always skipped lectures, wandered around, and stared out the window.
“I-Im Chan-woo, right?!”
“...You remember me?”
He smiled, amused. That smile felt entirely different to me now. Still, if he was someone I knew, maybe I could reason with him.
“Ch-Chan-woo. I’m really confused too, suddenly ending up like this... Think about it. We’re both young freshmen. We’re only twenty. Throwing your life away over a moment of impulse would be such a waste, right? So, so just calm down for a second...”
“A moment of impulse? What are you talking about?”
Chan-woo smiled playfully and pressed his grotesquely erect cock against my stomach.
“Hik...! Th-that’s... I don’t want to see you live a miserable life either. I-if you let me go right now, I’ll forget everything that happened today. So, Chan-woo, you...”
I tried everything I could to persuade him. The strength in the hand gripping my arm made resistance feel pointless, so I spoke as gently as possible.
“...You’re so noisy.”
“...What?”
“Could you be quiet for a bit?”
He grabbed both my hands, turned me around, and pressed his cock against my ass.
“W-wait! Chan-woo, you can still go back. Just calm down and let me go first...!”
“Shut up.”
He pressed the hardened length against my ass, against my anus.
“Wait, that hole isn’t—!! Oot?!♡♡”
It went into my ass. Wait, my ass? I’m a ‘doll,’ so I shouldn’t even have one of those. Something feels off... but whatever. I’m a ‘doll,’ so I don’t need to think about complicated things.
“....”
“Oh, you really did turn into a doll.”
The man who looked like the owner was pounding into my ass with everything he had while holding my arms. Ah, I see. This man is my Master.
“...Fucking amazing.”
“...Chup.”
The man who seemed to be my Master shoved a long rod deep into my ass and then stuck his fingers into my mouth. Salty.
...I want to move my tongue, but I can’t. I’m a ‘doll.’
Master touched every part of my body, using the rod inside my ass as support while groping both of my breasts. The arms he had been holding went limp and hung toward the floor.
By the way, what is Master doing right now?
...What? My body suddenly started trembling violently.
“Ugh?! It’s squeezing like crazy inside... So you can cum even in this state.”
“...Hng... Ugh....”
Cum? What does that mean? Anyway, my crotch feels kind of wet. I can hear water splashing on the floor. What is Master doing?
“...Let’s stop here for now. Then...”
The rod Master had shoved inside me slowly slid out. What was that—
“...Eh?”
W-what? Just now, I was with Master... No, Chan-woo was definitely... Huh? What... There’s this strange sense of discomfort. Was I really in this position earlier? I felt confused for a moment as I stared blankly at the wall, hands braced against it.
Then a strange, unfamiliar sensation began throbbing deep inside my navel, making my whole body tremble. I lowered my head.
“...Ah, aaah, ah?”
My legs started shaking. The tremor traveled up through my waist, stomach, and chest...
“Kyaaang?!♡♡ Ugh!!♡ Kahaah!!♡♡”
It reached my head. What, what is this♡ My mind is sparkling and flashing♡♡ Electricity, electricity♡ I can’t breathe under the violent waves crashing over me.
“...Ah, ha♡ Ang...♡”
When I came to, I was lying on the floor. I couldn’t even remember when I had fallen.
“Whoa... I didn’t think it would be this intense.”
A man’s voice. Who is it? Master? Ah, no. What am I saying?! Chan-woo. He was looking down at me, impressed.
“Alright, let’s do it on the bed instead of by the door, Seo-rin.”
Chan-woo picked up my limp body and carried me back into the room. I barely managed to part my powerless lips.
“P-please... stop...♡”
