The Trap Closes
"You tricked me into being in ovulation all day long. I didn't mishear you, right? That's what you said? So Jiyeon planned everything from the very beginning? You knew I'd need money. You knew I'd look for that clinical trial part-time job. You knew all of it?"
"Why the hell would you do this to me…"
"Because I wanted to break you."
"What kind of bullshit is that… You could've just beaten me up like before…"
"But you never submitted, even then."
Right after sex, I thought for a second that Jiyeon had changed. No, I guess I just wanted her to change. Was I doomed to never escape this delinquent girl for the rest of my life, ever since school? Where did everything go so wrong? I have to fix this somehow, even now. If things keep going like this, won't my life itself be in danger? And right now, with a woman's body, that includes sexually. I have no idea what else Jiyeon might do to me. She's already pinned me down once. And if I stay like this, I feel like I'll really end up corrupted as a woman. So, to somehow return to a man's body… I had to check. At the place where I first received the clinical trial injection.
"Jiyeon… Let's go back to the clinical trial building right now…"
"Why? Hm?"
"What do you mean why…? Obviously to turn back into a man…"
"Hey, that's not happening. You wanna die?"
"Then am I really going to die…? It's obvious you're just going to shove your cock into my pussy over and over from now on…"
Jiyeon looked at me and let out an annoyed sigh.
"Haa… Fine. I'll let you turn back into a man. Happy?"
"Really…?"
Jiyeon grabbed my wrist tightly.
"Let's go right now. If that's what you want, I'll send you back to being a man."
Still gripping my wrist, she dragged me out of the pharmacy. Is she really going to turn me back into a man? Something feels off. The way she's suddenly angry and hauling me along… no matter how I look at it, it seems like she's planning something again.
Before I knew it, we arrived in front of the building where we'd received the clinical trial. Jiyeon walked inside without hesitation. I had no chance to resist and could only follow behind her.
Once inside, the woman at the counter looked at us in surprise.
"Oh? Aren't you the people who did the clinical trial yesterday?"
"Yes, that's right."
Something felt strange. My body had changed from male to female, yet the receptionist recognized me immediately. What was going on?
"We came because something's wrong with my body. Is it possible to get an examination?"
"Yes, of course. Please follow me this way."
Before I could even ask anything, things moved quickly. We took the elevator up to the fourth floor again and arrived in front of the same examination room. Only I was brought inside; Jiyeon and the receptionist stayed outside talking. Why were they speaking separately? Could the whole setup to inject me have been planned with the receptionist from the start? My head started throbbing from overthinking.
I didn't know anymore. Even if I asked, Jiyeon wouldn't answer honestly anyway. All I could do was trust what she'd said—that she'd help me return to being a man.
After waiting a long time, the receptionist disappeared somewhere and Jiyeon approached me.
"I'll turn you back into a man, just like you wanted. Got it?"
"Yeah…"
"I heard from the nurse earlier. One shot and you'll go back to normal."
"Okay… And, just in case…"
"Hm? What?"
"You're really going to turn me back into a man, right…?"
Jiyeon fell silent for a moment, then smiled meaningfully.
"Of course. You trust me, right, Yurin?"
"No… After everything you've done, how could I…"
"Then what are you going to do? Live as a woman forever?"
"Don't be ridiculous…"
"Even if you refuse here, what can you actually do? You won't even get the chance to change your body back."
"Ugh…"
Jiyeon was right. Even if I screamed that my body had changed, who would believe me? They'd probably just call me a crazy bitch instead of helping. I felt cornered, with nowhere to go forward or back. Against my will, I'd been driven here.
Just then, the receptionist returned, carrying two syringes and a tray with two vials of medicine. She was now wearing a nurse's uniform, complete with mask and gloves. Two syringes? My question was answered immediately by Jiyeon's words.
"I'll get my injection first."
"Of course. Please sit here and roll up your sleeve."
So Jiyeon was getting an injection too? Why?
"Wait a second…"
"Hm? What is it?"
Both the receptionist and Jiyeon turned to look at me.
"I'm the only one getting the injection, right…?"
"Of course I have to get one too. That's the only way I'll return to normal as well."
The receptionist gave us an awkward look. More precisely, she looked at me. So because I was getting the shot to turn back into a man, she was going to return to normal too. After turning me into a woman and wanting to fuck me with her cock? Whatever. I was going back to normal anyway. Even my relationship with Jiyeon would go back to how it was. Being extorted by delinquent Jiyeon was better than this. Getting beaten up during school days was better than this.
"I'll wait then…"
"Let's just get this over with, okay?"
"Fine…"
I watched as Jiyeon received the injection in her arm. The medicine slowly entered her body. Once it was all in, Jiyeon suddenly started trembling. Her face flushed as she looked at me. What was this feeling? It was like her gaze was licking every inch of my body. Ugh. I didn't know why, but that wasn't important right now. It was finally my turn to get the injection.
Jiyeon stood up and I carefully took her place. I could feel her eyes on me from the side, but I decided to ignore it. That wasn't important now. Was I finally going back to being a man? Goodbye to this female body. At last.
"Please roll up your sleeve."
At the receptionist's words, I rolled up my sleeve and held out my arm. She tore open the syringe packaging, took it out, and carefully drew up the medicine. Looking closely, I noticed the color was different from what Jiyeon had received. The medicine slowly filled the syringe. Then the needle touched the skin of my forearm.
In that moment, the receptionist said something meaningful.
"You'll react right after the injection, so don't be too surprised. I'll help you then."
What? I didn't even have time to ask. The needle pierced straight into my arm. I watched the medicine slowly leave the syringe and spread through my veins from my forearm outward.
"Ugh…"
My heart suddenly pounded violently. My breathing quickened and I clutched my chest. This feeling… I'd felt it somewhere before. Don't tell me—
My whole body trembled. Pleasure shot up my spine to my brain, turning my mind white. My vision flashed, a moan escaped on its own, and I reached climax instantly.

"Uhaaang… haa, ugh… haat…!"
Strength drained from my body. My head fell back and I surrendered to the afterglow. I felt wetness below. Something was wrong, but there was no time to think. My lower abdomen throbbed and I climaxed again.
"What the hell is thiiis…! Uaaah… haaa, ugh… huuugh…!"
"Haaa, uungh… why is my lower belly… throbbing like thiiis… ugh, haaaat…!"
"Uhuuuh… haaak, aa… aaaang…! It's getting weeeird…!"
Orgasms kept coming without pause. Before the afterglow could even fade, another climax hit. My mind flashed like lightning, my vision flickering. Love juices sprayed from my pussy like a fountain, soaking my pants and running down my thighs. No, what was this? What the hell? What kind of injection was this to make my body like this? Why was I suddenly climaxing as a woman?
Just then, Jiyeon, who had been watching, suddenly rushed toward me. Hearing her footsteps, I barely managed to turn my head. Jiyeon was drooling, her face completely consumed by lust. The receptionist saw this and stood up to block her.
"Please calm down, patient…!"
As if telling her not to come closer. Jiyeon was clearly targeting me. Jiyeon charged forward and shoved the receptionist aside.
"Get out of the way."
"Kyaaah!"
The receptionist collapsed unconscious. Then Jiyeon immediately pounced on me.
"Uuuuh… uuuuuh…!"
The chair tipped backward and I was pinned to the floor.
"Khuuuuh… uhuuugh…!"

Jiyeon loomed over me. Her eyes weren't those of a predator anymore—they were completely drenched in desire. Different from when she'd attacked me at home. Like she was going to claim every part of my body as hers.
"Heehee… Nothing can stop me now. Yurin, I can finally get you pregnant with my cock."
"Wh… what did you saaay…?"
"The shot you just got? It turns your womb into a constant ovulation state for twenty-four hours."
"L… lies…!"
"Oh, and the one I got makes me stay in permanent estrus."
"Huuh…?"
"So right now, just looking at you makes my cock feel like it's about to explode. Look, Yurin."
"Hiii… hiiit…!"
It was exactly as she said. The front of her pants was bulging like it was about to burst. Her cock was swelling much larger than before.
"Don't believe me, Yurin? Then let's check what happens when my cum gets inside your womb."
"Noooo…!"
Jiyeon grabbed both my wrists and pinned them above my head, bringing her face close to mine. No matter how much I struggled, the continuous orgasms left me with no strength to resist.
