Hospital Hideout and the Onahole Morning
Patients stared at me oddly but turned back to the TV, apparently deciding I was just another nurse.
I approached the corner bed where Eunbi was supposed to be.
Peeking through the curtain, I found her already changed into a hospital gown and lying on the bed. The pale blue fabric with its subtle check pattern was soft cotton, and "Seohan University Hospital" was embroidered over the chest. She looked so natural playing patient that it was hard to believe she'd been in nothing but underwear just moments ago.
"What took you so long?" Eunbi asked, shooting me a sideways glance.
"I'm being chased..." I panted.
"What?"
"No time to explain. Just hide me."
Eunbi instantly grasped the situation and flipped the blanket up.
"Get in. Quick."
There was no time to hesitate. I climbed onto the bed and lay down beside her. The blanket settled over both of us.
Two people on a narrow single bed meant our bodies were pressed tightly together. I could feel the warmth of Eunbi's body against my side, and the clean scent of laundry from her gown brushed my nose.
"Who's chasing you?" she whispered.
"My preceptor... Nurse Han Jiyeon."
"Ah, the one who's been bullying Eunyoung?"
"Yeah..."
We held our breath and listened. Footsteps echoed in the hallway, then faded. My heart was still pounding, and being this close to Eunbi made my face burn.
Her body was pressed against my side. Even when I'd been squeezed against Eunyoung in the cabinet earlier, my heart had felt ready to burst, but lying with Eunbi felt different. Her figure was far more voluptuous, soft and plush, and the gentle brush of her shoulder and arm against mine kept drawing my attention. Whether it was the bed or the sheer volume of her body, my heart raced wildly.
We stayed huddled under the blanket for a while. I strained my ears toward the hallway, but no one came looking. It seemed Han Jiyeon was searching elsewhere.
"We should get out now," Eunbi whispered. "If that suspicious nurse already spotted you, we can't stay here. Come on."
I threw off the blanket and climbed out of bed. Eunbi rose in her patient gown, and I handed her the clothes I'd been carrying.
"These are the ones I borrowed from Eunyoung. She asked me to get her some clothes."
"Oh? I already have the gown, so I don't need them."
Eunbi waved the offer away. She looked surprisingly comfortable in the patient outfit and showed no sign of complaint.
"Then I'll wear them."
I quickly unfolded the clothes. The thought of finally taking off this ridiculous nurse uniform and putting on a normal shirt and jeans was a relief.
"Whoa, whoa, not happening," Eunbi said, snatching the clothes from my hands.
"Why?!" The sound that came out was almost a shriek.
"Please, just let me wear them! How am I supposed to walk out of the hospital dressed like this?"
"Well..." Eunbi gave me a meaningful smile. That smile always meant she was plotting something.
"If you grant me one little wish, I'll let you change."
"W-what kind of wish...?"
An uneasy feeling wrapped around me. Nothing this woman asked for was ever ordinary. She wasn't about to make me cross-dress again, was she?
"I'll tell you later," Eunbi said, waving her hand. "It's nothing too dramatic, so you don't have to look so terrified."
Not too dramatic? I already knew from experience how terrifying her idea of a "reasonable request" could be. But walking out of the hospital in this nurse outfit was even worse.
"...Fine. I'll change first."
I finally surrendered.
"So we have a deal?" Eunbi held out her pinky.
It was ridiculous, but I hooked my finger around hers anyway.
I closed the curtain and started changing. I unzipped the back of the nurse uniform and peeled it off. Cool air hit my bare skin. Still wearing the bra, stockings, and panties, I put on Eunyoung's clothes.
The light blue shirt buttoned up, but the chest area was tight. Eunyoung was only 155 cm and slim, so the clothes were small all over. The jeans were worse. The thighs felt like they might split, and the fabric stretched painfully over my hips. It took forever to get the zipper up, and once the button was fastened, breathing became difficult.
Ironically, the tight women's clothes were far better than the nurse uniform. At least my thighs weren't exposed and my back wasn't open.
"All dressed?" Eunbi called from outside the curtain.
"Yeah..."
I stepped out. Eunbi looked me up and down and smirked.
"This look is pretty damn hot in its own way."
"...Whatever. Let's just get out of here."
I stuffed the discarded nurse uniform and accessories into the bag and left the room with Eunbi. She was still in the patient gown while I wore the tight women's clothes. We walked side by side down the hallway. The stares were still there, but nothing compared to when I'd been in the nurse outfit.
We took the elevator to the first floor, crossed the lobby, and stepped out the main doors. Night air brushed cool against my face. I had finally escaped that hellish hospital.
We walked along the street lined with streetlights. It was past eleven, so the area was quiet except for the occasional taxi headlights cutting through the dark. Eunbi wore nothing over her gown, looking like a patient who had just escaped the hospital.
"So what happened that made you so late and got you chased by a nurse?" Eunbi asked. We hadn't had time to talk properly in the room earlier.
I told her everything except the part where I kissed Eunyoung. I explained my suspicion that the head nurse was stealing medicine and sent her all the photos I'd taken: the bag of drugs, the inside of the cabinet, even the name tag that read "Park Miyoung." Over twenty shots in total.
Eunbi scrolled through the photos one by one, then smiled that meaningful smile again. The corners of her lips lifted and her eyes curved like crescent moons—the expression she wore whenever she had a plan.
"This is perfect."
"What is?"
"With this, we should be able to solve Eunyoung's problem."
She sounded confident. She didn't explain exactly what she intended to do, but that look told me she already had a clear picture in her mind.
We parted at the subway station entrance. Eunbi waved and headed in the opposite direction while I boarded the train in my tight women's clothes. Thankfully it was late, so there were almost no passengers and I didn't have to worry about stares.
By the time I got home, it was nearly midnight. I opened the door to a dark apartment. The living room lights were off, and no light leaked from my sister's room.
"Jiheon?"
I called softly, but there was no answer. She really wasn't home. She must have been studying late at the reading room. Being a retaker, this was probably the final sprint period for her.
I let out a sigh of relief and went to my room. The last thing I needed was for my sister to see me in these tight women's clothes.
I collapsed onto the bed and stared at the ceiling, replaying the day. Cross-dressing and sneaking into the hospital, getting pegged by Eunbi again, hiding in the cabinet and kissing Eunyoung, discovering evidence of the head nurse's theft, being chased by the preceptor, hiding under the blanket with Eunbi...
What a chaotic day.
After showering, I hid the women's clothes in the closet. The outfit Eunbi had forced me to buy, Eunyoung's nurse uniform, her casual clothes, the bra and panties—all crammed into the corner and covered with an oversized T-shirt. Once everything was hidden, my eyelids grew heavy. Fatigue hit all at once, and I fell asleep immediately.
---
I woke from a shallow sleep to something pleasant happening below my waist.
What is this feeling...? I'd never put my cock inside a woman's pussy before, but this sensation was unmistakably like one. Was someone riding me while I slept?
If so, the only woman in this house was Jiheon...
Startled, I snapped awake. Even if it was my sister, I really hoped she would hold back on something like this. When I opened my eyes, I saw my little sister in her underwear straddling my thighs, vigorously rubbing my cock with a pink onahole.
"Ah, you're awake, Oppa? Good morning. Though you could still sleep a little longer."
Without permission, she sat on my thighs in nothing but panties and greeted me sweetly while furiously working the onahole up and down my shaft.
Was it even morning? The blackout curtains made it impossible to tell the time.
"W-what are you doing...?"
"Hehe, this is called an 'onahole.' It's a male masturbation toy made of silicone to imitate a woman's genitals."
"I know what it is... but why are you using it on me?"
"On the way home yesterday I happened to spot a 24-hour adult store. It looked like fate. I remembered how you always jerk off with your hand, so I bought this to give you a new experience."
Using an onahole for the first time felt just as intense as being pegged by Eunbi. Waking up to my cock being rubbed by one without any mental preparation was overwhelming.
I tried to push my sister off and stop her before she saw me in such an embarrassing state, but...
I was completely naked, lying on my back with both wrists bound to the bed frame above my head with cable ties in a "hands-up" position. I couldn't do anything except wiggle my fingers.
"Nngh, what the hell?! Untie me right now!"
"If you keep struggling like that, I'll tie your legs too. Just stay still~"
Jiheon used the snap of her wrist to move the onahole even faster. The bumpy, ridged interior wrapped tightly around my cock, creating a completely different sensation from using my hand. The unfamiliar stimulation made my hips twitch and tremble. I couldn't last even ten seconds.
"Uwah! Ahh... stop! I'm gonna cum! Please, stop...!"
"Oh my, you're about to cum already? I guess you really like the expensive onahole I bought. Hehe. Then go ahead and cum. Pretend this onahole is Jiheon's pussy and shoot everything inside."
"Hngh! Haa, haah, aaaaah..."
Spurt, spurt...
With my pathetic moans, thick ropes of semen erupted with surprising force. Even while I was cumming, Jiheon kept shaking the onahole. After nearly ten seconds of trembling, I let out a deep sigh as the orgasm finally ended.
The shame of having just cum inside an onahole while naked and tied up in front of my sister hit me hard. I wanted to die from embarrassment.
Jiheon pulled the onahole off my cock. The ridges scraped over my oversensitive glans on the way out, making me shudder. A mixture of lube and my own milky fluid dripped from the entrance, trailing down onto my stomach.
My sister brought the dripping onahole to her mouth and licked up the liquid with obvious enjoyment.
"Mmm... Oppa's cum... it's thick and delicious..."
I'd tasted the fake semen Eunbi had made at the hospital by accident, but the real thing had a fishy, astringent taste that made "delicious" impossible to say. Just watching my sister drink the real thing made me feel nauseous.
"Jiheon, if you're satisfied now, can you untie me...? If you let me go right now, I'll pretend this never happened. Hurry."
"Hmm..."
Jiheon finished licking the onahole clean, climbed off me, and walked over to the closet. She pulled out all the women's clothes I'd hidden and spread them out in front of my eyes.
"Oppa, what are these women's clothes? They smell like other women mixed with your scent... If you cheated, just admit it honestly. Even if I'm going to be your future wife, I can't forgive lies."
"That's..."
The fact that I even had to explain this to my sister was absurd. We weren't dating, let alone getting married. We were just brother and sister. Nothing more, nothing less.
But with me naked and tied up like this, it was probably best not to provoke her.
