Once inside the house, the first thing I did was strip off my clothes and rush into the bathroom.
I wiped the fluid that had dripped between my legs again and again.
After scrubbing until my skin turned red, I cooled my heated head under cold water.
…Lately, it seems like something is off about me.
Initially, I didn't think much when I felt something from having my chest touched.
I thought maybe it wasn't strange to feel something when touched by pretty girls.
So, when they suggested doing a test, I could accept it somehow.
Because I was sure I wasn't a pervert.
Though the process of passing the test might be hard, I stayed true to myself.
But to find myself thinking I want someone to notice I'm wearing racy underwear…
This is clearly wrong.
Is it my mind that's gone awry, or my body?
"Sigh…."
Even when I think about it, no answers come.
Or rather, I know the answer, but I'm close to denying it.
But I can't admit it.
The moment I admit it, I'll lose the right to be by their side….
I turned off the shower and looked in the mirror.
…A ridiculous sight of a drenched mouse was staring back at me.
Pull yourself together.
There's no point being by Eunjeong and Hanna's side in this state.
Don't get discouraged, just gather your strength and confidently pass the test.
As I left the bathroom and was about to get dressed, I discovered the thong.
I need to get used to this quickly too.
Resolving to stay focused, I put the thong back on.
Since there were no eyes on me, it didn't feel as provocative as it did outside.
The sensation of the string buried in the crevice, the small beads brushing or pressing against and stimulating me?
…Is it odd that these kinds of stimuli feel like nothing?
Just like when I used to try masturbating at home and didn't feel much, I seem to have a surprising tolerance for things done without external stimuli.
What in the world is up with my body….
Still, I can't avoid practice, so I'll keep wearing it.
With the thong on underneath, I put on black dolphin shorts and a white T-shirt.
"Ugh…"
Stretching and glancing at the clock, I saw it was past dinner time.
…Maybe I should stop by the convenience store.
While checking out the shelves at the convenience store near my house, I got a call from Eunjeong.
"Oh, Eunjeong. What's up?"
"Seon-ah. I'm near your house... and I was hoping I could stay over if it's okay."
"Huh? Didn't you say you had plans?"
"I did, but it got canceled because a few people didn't show up."
"Then come to my place and..."
But why does her voice sound so vivid?
I turned my head to the right, and sure enough.
Eunjeong was standing there with a phone in her hand, smiling brightly.
Cha Eunjeong hugged me.
I barely had a moment to feel her soft body when Eunjeong's hand suddenly started slipping inside my pants.
"E-Eunjeong?"
"Hmm... You're wearing the panties I gave you? I thought you'd change into something else when you got home, but I'm surprised."
"No, it's just... I'm trying to get used to it..."
"Hmm... For trying to get used to it, it's a bit too wet, isn't it?"
Eunjeong was looking at me while playing with her index and middle fingers, sticky with fluids, as if she was a police officer catching a suspect at the scene.
I really wore it to get used to it...
But when I see Eunjeong's expression, which seems to say, You secretly enjoy this too, don't you? I can't help but wonder if I really didn't have such feelings.
The desire to wear such provocative panties out in public once more, to draw others' gazes, and to relive that thrilling, suggestive feeling—did that desire really not exist?
Considering how I ended up wearing this thong outside, it would be more reasonable to just order delivery instead of going out to buy lunch.
So why did I go out anyway?
Doubting myself causes even my confidence in my own thoughts to waver.
"It's okay, Seon-ah. I'm your friend, right?"
"Uh, yeah..."
"So, even if you're curious about these things and decided to wear them out again, I won't say anything."
"..."
Eunjeong tightly clasped both my hands.
The warmth I could feel from Eunjeong's hands.
"Be honest. You wore the thong out because you wanted to experience that sexy feeling again, right?"
"Well…."
"Answer."
"…Yeah."
Listening to Eunjeong's gentle voice, my mind gradually calmed.
Yeah, Eunjeong, who tries so hard to understand, embrace, and watch over me, couldn't be wrong.
If anyone's wrong, it would be me.
"It's okay. It can happen... Surprisingly, many women have this kind of interest. So there's no need to hide it too much."
"…Thank you, Eunjeong."
I felt like I might cry a little.
Is it possible for someone to be this kind?
Hanna too, all my friends around me are such good people.
"Right, this is perfect timing. I can help you!"
"Huh?"
Eunjeong wrapped her left arm around my waist and slid her hand down from my abdomen to grab the string of my panties.
...What?
"There's CCTV over there, so whatever happens, you can't react, okay?"
"Wait, what are you doing... Ah!"
Eunjeong suddenly pulled the front of the thong upwards, causing the beads to rub against my aroused clitoris.
For a moment, sparks flew before my eyes, and I almost collapsed, but I managed to hold my ground thanks to Eunjeong firmly gripping my waist.
I tightly covered my mouth with one hand and glanced around.
Fortunately, we were the only customers, and the staff seemed absorbed in their phone, paying no attention to us.
"Mmngh... Uhh..."
The beads moved up and down with Eunjeong's touch.
As my excitement grew, my clitoris swelled, and I felt the beads tapping against it more intensely.
My strength started to give out, and I began to wobble, so Eunjeong pulled me closer to lean against her body.
"Feels good, doesn't it?"
"N-no... Ngh… Just so-so…"
Even though Eunjeong seemed to approve of my outing... that's another matter. If I show too much of a reaction here, it might ruin the 'test.'
I have to play it off as if I wore this out of mere curiosity...
"Hnnng... Uhngh, hnnngh, huh!"
As soon as I finished speaking, Eunjeong's hand pulling on the thong quickened.
What was initially a slow, intermittent tugging became a relentless swish-swish-swish, making me worry that my clit might swell.
"How about now? Is it still just so-so?"
At Eunjeong's question, I couldn't open my mouth, fearing a moan might escape, so I just shook my head vigorously.
I absolutely, absolutely can't admit it.
I shouldn't admit it, yet my mind started to feel hazy, and my clit felt as if it were scorching hot.
If this keeps going, we'll get caught….
Somehow, I managed to lift my head from its downward slump and glanced over at the counter.
The staff member was engrossed in their phone...
But if she were to look up now, she would see me leaning against Eunjeong as if nestled in her arms, covering my mouth with a flushed face, trembling.
Anyone would find that scene suspicious, and if the staff were to approach, asking if the customer is okay...
In that place, there I was, climaxing in an unsightly manner with my thong being tugged by a friend, causing fluids to drip uncontrollably….
The moment I imagined being caught in this state by the staff, a chilling sensation ran through my entire body.
Standing on tiptoe with my legs pressed together, I couldn't help but climax.
I felt the fluids not just soaking my dolphin shorts but trickling down my thighs, yet with both hands clamped over my mouth, I couldn't do anything about it.
Weakened by the afterglow of climax, I completely missed the presence of someone approaching from behind.
"Ma'am? Are you okay?"
"Ah…."
My mind went blank.
What should I do now? How do I explain this? What if they call the police?
While resentment towards Eunjeong, who pushed me to this point, bubbled up, I suddenly became curious about how the staff was looking at me now.
Were they looking with genuine concern for a customer, with suspicion, or with... contempt?
"My friend seems to be feeling unwell due to her period right now. I'm sorry for causing you concern."
"Oh, okay…"
Eunjeong came up with a plausible lie to send the staff away in my stead when I fell silent.
…I don't remember much after that.
I just remember leaning on Eunjeong as we walked, and before I knew it, I found myself lying on my bed.
And Eunjeong was sitting beside me.
Looking at her smiling, I felt a slight sense of annoyance.
"Why are you looking at me like that? Did I do something wrong?"
"…"
…Could Eunjeong have known and acted that way?
She was just trying to help me.
Of course, there was probably an intention to test me as well…
But she surely didn't intend for me to lose control so disgracefully.
Still, when the staff caught us, it was terrifying.
…Truly.
I turned towards Eunjeong and wrapped my arms tightly around her waist.
