Physical Examination
“……”
“What's wrong? Oh, don't tell me you're the type who likes being stripped?”
“N-no, of course not…!”
Her sly words paired with that cold expression. At this point, it was definitely Yoon Yerin, but somehow that made it even harder to take off my clothes. Especially since being told to strip in a situation like this ultimately meant…
…She wants to make me do that kind of stuff.
Of course, the Yerin I knew wouldn't do that, but with a gun pointed at me, the possibility was high.
Please, just stop already…
And then, that scene from yesterday flashed in my mind. …That woman had been through something horrific. Her hole had been relentlessly fingered until finally… I shook my head sharply.
Thinking about it now wouldn't help anything. So, with trembling hands, I grabbed the hem of my shirt. And before a bullet could pierce me, I started undressing.
The first part of my skin to be exposed was my abdomen. I'd been barely holding on with just this one T-shirt, so as soon as it lifted, a chill hit me.
Thud.
The T-shirt fell limply to the floor, and my breasts were fully revealed.
“W-why aren't you wearing anything underneath?”
Yerin seemed a bit flustered at the sight of my bare chest.
“I couldn't do laundry…”
“Then… you're not wearing anything down there either?”
…Nod.
Truth is, I just didn't want to wear women's underwear…
But saying that would make me look suspicious, so I decided to brush it off vaguely.
“…Move your hands. I can't see your breasts.”
“…Okay.”

In the meantime, I'd subtly been covering my chest, and she caught me. So now, they were even more fully exposed.
“…Keep undressing.”
Her command to continue made my body tremble even more, but I couldn't stop.
I feel like dying of embarrassment…
An overwhelming wave of shame surged through me.
…But she doesn't seem like she's planning anything weird.
Then why make me strip? Midway through undressing, curiosity got the better of me. I decided to carefully ask the reason without upsetting her.
“……”
Yerin didn't answer at first. Then suddenly, she crossed her legs and leaned forward.
“S-see? The gallery post was a lie…”
“That's not it. I need to check for bite marks.”
“Bite marks…?”
Instantly, my face flushed as hot as when I'd sent that selfie yesterday. So, she wasn't stripping me because she was interested in my body…
She's checking if I'm infected anywhere…
Thinking about it, it was obvious. From Yerin's perspective, letting an outsider in meant she had to be cautious. I might have hidden an infection, so this was a completely standard procedure.
“Oh, r-right.”
Seeing the relief on my face, Yerin smirked.
“What? Did I look like a pervert who wanted to see you naked?”
“Ah, no, it's not that…”
She'd hit the nail on the head, leaving me speechless.
“Well, whatever. We're going to be living together from now on, so better to be sure, right?”
Living together.
That phrase filled me with anticipation. It might be jinxing it, but if there were no bites, it meant I could stay here right away. My mood improved a bit from moments ago.
So next, I started pulling down my black tracksuit pants.
…Thud.
Twitch.
But this time, something was different from before. It wasn't a problem on my end. It was precisely Yerin's reaction the moment my pants came off that seemed suspicious.
What's with her?
More specifically, she kept fidgeting her legs. Or suddenly placing a cushion on her thigh.
It wasn't that strange, but it felt oddly off.
“…I'm all undressed now.”
Anyway, the long, drawn-out undressing was finally over. My honest feeling now that I was completely naked? Still embarrassed, of course. Especially how my body shivered every time the air brushed against it.
…Squeeze.
I'd only crossed my legs a little, but an even tougher demand came.
“Come closer.”
After a brief hesitation, I took a step forward.
“……”
“Closer.”
“……”
“More.”
“……”
Yank.
“Eek!”
Suddenly pulled forward, Yerin's face came into view right at my stomach level. Her breath was touching my skin.
“…Let me listen to your breasts.”
“L-listen to my breasts?”
“The undersides and such aren't visible. I can't touch them myself, you know?”
“Ah.”
As instructed, I carefully cupped the undersides of my breasts with my hands. A soft, squishy sensation transmitted to my fingertips.
“…Now raise your arms high.”
Next, she wanted to check the sides of my breasts and armpits.
“…But if you're checking, wouldn't it be better to stand up and look? It's hard to see properly from sitting.”
Yerin seemed to ponder my words for a moment.
“…Yeah, that makes sense.”
She quickly agreed, then leaned forward while still seated. Without a word, she placed her hand on my thigh.
“Eep, y-you didn't say you were going to touch…”
“To check properly, I have to touch. Just bear with it a little.”
Stroke.
Brush.
…Tap.
“Eep…!?”
As her hand stroked my thigh, I almost yelped without realizing. Simple reason.
“W-wait, hng…”
Just like it looked now, the back of Yerin's hand brushing there as she touched my thigh.
B-but…
The first time was probably an accident, but n-now it felt intentional… Plus, was there any reason to inspect my inner thighs so thoroughly?
As suspicions grew with each successive touch, she spoke up.
“…You must be tired from standing. Once the check is done, I'll feed you, so hang in there a bit longer.”
The word “food” instantly gave me strength, even amid these thoughts.
Yeah, this is just a necessary procedure, right?
And I'd get to eat if I endured just a little more. S-so, really, just a bit longer.
“Then…”
But the next spot to check was the problem.
“Turn around.”
“Okay…”
“In that position, bend over and lift just your butt.”
“O-okay… w-wait, lift my b-butt…?”
What did she just say? For a moment, I thought I'd misheard. And understandably so—being naked-examined by a junior I knew wasn't enough; now this…
Bend over and lift my butt up.
I'm not some pet. Exposing everything like that was impossible.
“…Can't do it?”
But I'd forgotten something about Yerin. She was incredibly good at reading expressions. Meaning she knew exactly what I was thinking right now, and furthermore, what it would take to get compliance.
“Listen to me carefully from now on.”
Sure enough, Yerin grabbed my trembling hand and continued.
“There's enough food here to last a lifetime, hot water you could use endlessly without worry, electricity and everything else in abundance—no need to fret about any of it.”
“……”
“But what's it like outside?”
…Outside? Horrific zombies overflowing, even more horrific humans… No hot water or electricity, not even food—reduced to eating dirt.
“Right. That's what I saw too. But like I said, inside here, none of that's a concern. There are even game consoles, so you won't get bored.”
“……”
“…So, you still planning to just sit there?”
“B-but…”
“Fine. I don't force anything anyway.”
“Huh, then…”
“Just go back out the way you came in.”
“Eh…?”
Her words made my heart sink like it had at the entrance. No, maybe even worse. Back then, there was still hope, but this meant it was over.
Maybe that's why my body trembled uncontrollably compared to before, on the verge of tears.
“I-I'll do it. I'll do it, so…”
…Stroke.
In the end, I turned my back to Yerin. And not content with that, I lifted my quivering butt toward her.
“…It'll be over quick.”
Obviously, facing away, I had no idea what she was doing. Whether she was inspecting closely or even planning to touch here—I couldn't tell. It felt like her breath was close, and the longer the silence stretched, the more my waist shook.
“All done.”
Finally, after what felt like an eternity, those words came, and my legs gave out.
“Um, so then…”
“Shower first before eating.”
Hearing that, tears streamed down my face. The whole ordeal replayed in my head, bringing overwhelming relief.
“Ah, the shower's that way. Clothes are hung up next to it—wash up comfortably and come out.”
“S-sob, th-thank you…”
Even somewhat calmed, words still wouldn't come easily. Crying in front of a junior I knew was embarrassing, but I didn't care.
“…I'll wait for you with food until you're done washing.”
I could eat. That was enough. At Yerin's words that she'd wait, I quickly said I'd prepare something right away.
“Looking forward to it.”
“…Um, but I've been wondering since earlier.”
Stroke.
“I-isn't that position uncomfortable?”
It was literally a posture like getting smacked by your mom. Pointing at her legs, Yerin looked a bit flustered.
“I-It's fine, so hurry and wash up. I'm starving from all this waiting.”
“Ah, yes.”
She freaks out even when I worry.
…Still, I'm really going to live here now.
I honestly hadn't thought I'd make it this far. Thinking about it brought tears again.
“Ah, you still haven't gone? I said I'm hungry.”
“Oh, s-sorry. I'll wash up quick and…”
Right then, I spotted something odd. Yerin's urgent demeanor drew my eyes to the sofa, where something bulging on her thigh caught my attention.
What the heck is that…?
