Having Bared Herself to Her Husband's Friend, She Was Asked the Unthinkable
Without a single thread of clothing on him, her friend Ju Seonghyeon walked into the shower room.
Lee Yena was so startled by his entrance that she couldn't even scream. Unable to meet her friend's eyes, she turned her gaze away.

She curled in on herself as much as she could, covering her breasts and pussy with her hands.
But that only lasted a moment.
R-right… Seonghyeon is… the gym master, isn't he?
It wasn't unthinkable for Ju Seonghyeon, the master of the dojang, to walk into the shower room — or even to end up showering alongside her.
We already saw everything of each other during the roleplay last time…
The moment that thought settled in, she let the tension drain from the arms she'd wrapped around her body.
Not that she could bring herself to look at Ju Seonghyeon outright, or turn her body toward him.
I-it still is a little… embarrassing…
Before he was the gym master, Ju Seonghyeon was her friend — and a man. Even if she'd already shown him everything once, that didn't mean she could bare it all without a shred of shame every single time. She would have been embarrassed even if it had been another woman.
So Lee Yena stood under the hot water and angled her body slightly away from him.
"Weird how in summer you still break a sweat right away even with the AC on, right?"
"Y-yeah… I-I guess so…"
Ju Seonghyeon came and stood casually beside her. The shower room wasn't that spacious to begin with, so he hardly had a choice.
Which meant that for Yena, standing there awkwardly—
—Smack!
"Kyaah…!"
"What are you being so shy about, Yena?"
His hand came out of nowhere. Just like during their sparring practice earlier, Ju Seonghyeon's large, thick palm cracked against her ass.
This time it was bare skin, not over pants, so the sting bit sharp. And at the same time, something else flickered through her too…
Anyway.
At his sudden swat, Lee Yena glared up at him with tiny tears welling in her eyes — carefully keeping her gaze fixed on his face, refusing to let it drop any lower.
"Seonghyeon, you…"
"Sorry, did that hurt? From the way you were reacting earlier, it looked like you kind of liked getting your ass smacked by me."
"W-who would like something like that? There's no way…"
Her voice shrank a little at the end, but Lee Yena firmly denied her friend's words.
She could never say it out loud.
The truth was, every time she failed the spray-can drill during class and Ju Seonghyeon spanked her as punishment — that brief sting, the simple fact of someone smacking her ass — had given her a strange little thrill. Every time he hit her, her pussy had started to itch.
And just now, when he'd spanked her bare ass and the pain had bitten harder than before…
She'd felt a little spark of electricity.
G-getting off on your friend spanking your ass is… that's what perverts do… that's a total pervert thing… I-I'm not that kind of person.
It was a humiliating truth Lee Yena would take to her grave.
So she buried that unspeakable fact deep in her chest and flipped the question back on him instead.
"M-more importantly, what do you mean, why am I embarrassed… Aren't you embarrassed? You're… completely on display in front of me…"
Showing each other their bodies in the dojang's locker room or shower might not be strange for a gym master and his student — but even if it wasn't strange, embarrassment was still embarrassment.
"What are you talking about. Of course I…"
"Of course…?"
—He shrank in on himself a little.
"…am embarrassed. Could you not stare quite so hard?"
"…Huh?"
Apparently he felt the same way, because he exaggeratedly curled up and covered himself. The sight of it made Lee Yena laugh.
"Pfft… What the heck~ You're just the same."
"How could I not be?"
"Right? So I'm not the weird one…"
"Still, we're going to be seeing and showing each other a lot from now on. I was just trying to act natural so you wouldn't feel self-conscious…"
"Ah… O-oh, so that's what it was… I had no idea… I'm sorry."
But his next words made Lee Yena reflect on her own behavior.
Feeling embarrassed is only natural… but Seonghyeon was pretending to be fine for my sake… God, I'm such a jerk…
She couldn't even manage to return the consideration of a friend — she'd failed to notice his thoughtfulness and made him say something like that. She felt pathetic.
Yeah… like Seonghyeon said, as I keep training with him, he'll… touch my ass sometimes… and there will definitely be more days like this when we shower together… I can't keep making him uncomfortable by acting embarrassed every single time.
Lee Yena made up her mind.
Even if she couldn't actively help her friend, she at least wouldn't be someone who made things harder for him.
"Hahh…"
She took a small breath before speaking.
And then, to Ju Seonghyeon — who still looked a little awkward after their exchange, that friend who looked like a bear on the outside but always carried consideration and a kind heart for others — she found her courage.
"Hey, Seonghyeon."
"…What?"
"I'm sorry. Like you said, I should just get used to it, but I keep getting embarrassed and making things weird for you…"
"That's… not it. You're allowed to be embarrassed. Gym master or not, I'm still a guy. Don't worry about it. I'll be more careful."
"Mm-mm, no. Why should you be careful?"
As they talked, Lee Yena felt her heart grow lighter. Even now, her friend's determination to look out for her only made her shame and hesitation feel smaller still.
—She turned.
Lee Yena pivoted toward Ju Seonghyeon. As she did, she even clasped her hands behind her back — so that her body would be fully, openly visible to him.
She could feel her face burning red with the embarrassment that still lingered, but it wasn't enough to make her curl up and cover herself again.
And so.
Among every man who was not her husband, only to Ju Seonghyeon — gym master and friend — she offered without hiding them: her fair, round breasts; the soft folds of her pussy, parted ever so slightly; her entire beautiful naked body.
"Listen, Seonghyeon. From now on, let's agree not to get embarrassed about this kind of thing with each other. I know it's pretty pathetic for me to say that after I was the one who started acting weird first, but…"
"Yena…"
"I'll try harder from now on. You're giving it your all as the gym master — I don't want to be the only one getting all shy and making a mess of things."
"…Yeah. Let's do that."
And Ju Seonghyeon answered her proposal. Just as she had, he turned so they were facing each other.
Then she saw it — her friend's body, which she had never truly looked at in detail, never even thought to look at. That solid physique she'd glimpsed a little during the roleplay last time, strangely lingering only as a hazy memory, came into clear view.
Lee Yena burst out laughing.
"…Heh… huhuhu…"
"What? Why are you laughing like that. Is my body that funny?"
"No… it's just somehow hilarious… huhuhu."
Standing in the shower like this, showing each other their bodies — it was embarrassing and awkward, and yet the whole situation struck her as absurdly funny.
So as she laughed, as she resolved not to look away from his body or hide her own any longer—
—It stiffened.
"…Ah."
Ju Seonghyeon's cock entered her field of vision.
It looked rock-hard even at a glance — and though she knew she shouldn't make the comparison, it was far larger than her husband Yun Jaemin's. Her friend's thick cock stood pointed toward the ceiling.
—A tight clench deep in her belly.
In that instant, the sensations from the roleplay — the ones that had been fading like a dream — made her lower abdomen throb. The memory of that massive thing driving into her pussy, churning all the way to her deepest point.
Of course it had only been acting, only a performance and not real sex… but that day's events came flooding back, vivid and soft and wet…
—She swallowed hard.
Lee Yena gulped without meaning to and asked her friend in a trembling voice.
"S-Seonghyeon… that… why… why did it get so big…?"
"This? Well… uh… hear me out without getting the wrong idea, okay?"
"Y-yeah…"
"Guys are just… physiologically wired that way. When we see a woman's naked body… you get the general idea, right?"
"Ah, aaah~ Right… yeah… so that's…"
"And if it's a woman as pretty as you… well, let's just say standing at attention is pretty much a given."
"Eh?!"
"What?"
"P-pretty… me…?"
"Come on, Yena. Setting aside the fact that you're Jaemin's wife and my friend — objectively speaking, you're gorgeous. If you try to deny that, you know that's just straight-up delusional, right?"
"…Huhuhu, is that so?"
"Why are you acting like this is news. Anyway, obviously I'm not going to get any weird ideas about you — but between all those factors put together, this is what happens. So just ignore it."
"Huhu, okay."
Because their connection ran through her husband Yun Jaemin in the middle — and because he'd become her friend too — Ju Seonghyeon had never used such a flustering word as "pretty" before. It caught her off guard.
But once she listened, all of it made sense.
It was a man's physiological response. There was nothing to be done about it. As a married woman, she wasn't ignorant about that part of men.
Though Jaemin lately has been… mm, no. He's just tired, that's all.
Even when she slipped into something a little sexy, he always told her she looked pretty — but he never actually had sex with her. Her husband flickered briefly through her mind.
Lee Yena quickly shook the thought away.
It wasn't that she'd stopped being an attractive woman to him. He was just busy with work and exhausted, that was all.
I'm glad I could talk it through with Seonghyeon like this.
More than anything, she was grateful she and her friend Ju Seonghyeon could speak honestly without misunderstanding each other. Even if facing one another like this still felt unfamiliar and made her hesitate for now, she was sure this would bring them even closer.
Feeling a warm glow settle in her chest, Lee Yena started to turn back to her shower. Even if they'd agreed to stop hiding their bodies, there was no reason to keep staring — and she'd come into the shower room to wash in the first place.
But then, suddenly—
"…Hold on, Yena. Sorry, but can I take a look at something?"
"Huh?"
Ju Seonghyeon called to her. His face was serious, without a trace of teasing.
Wondering what on earth had gotten into him, Lee Yena obediently turned toward him — uncovered, just like before, breasts and pussy fully exposed.
And then—
—Thud.
"S-Seonghyeon?"
"Shh. Just a second… something's bothering me."
"Mm… o-okay…"
Ju Seonghyeon dropped to one knee and began staring intently at her pussy.
Even so.
Having a man stare straight at her private parts like this — she couldn't help but shrink in a little. But his expression was so utterly serious that she did her best to hold her pose.
"……."
Ju Seonghyeon simply looked, saying nothing.
At her pussy.
Under her friend's gaze, Lee Yena felt her body growing hotter and hotter.
Seonghyeon is… looking at me down there like that… nn…
—A tight clench.
No… why am I… getting wet…
The shower water was running down her body, so he probably wouldn't notice — but she still worried he might somehow realize her pussy was soaked.
And then, without warning—
—His finger dragged through.
"Hyaaaan…!! Hn…!"
—Her body jerked.
Ju Seonghyeon's index finger traced the cleft of her mound. In less than a second, the jolt of pleasure that shot from her pussy through her entire body made her tremble — and at the shameful moan that burst out on reflex, she clapped a hand over her mouth faster than she ever had in her life.
From that position, she looked down at the friend who had touched her pussy without a word.
"……."
—He rubbed his index finger against his thumb, studying the slick of her juices coating them.
O-oh no… he caught that I was wet…
Shame and embarrassment surged up all over again, but she still didn't blame Ju Seonghyeon. Looking at that deadly serious face, all playfulness stripped away to nearly zero, she couldn't help thinking he must have had a reason.
She was just mortified that her pussy had gotten wet under her friend's gaze — and that he'd found out. Of course, he had no way of knowing it was his gaze that had done it.
And so.
While Lee Yena barely managed to breathe, enduring the humiliation and shame, Ju Seonghyeon spent roughly a full minute studying the wetness on his fingers before rising to his feet.
"Yena."
"Nn… y-yeah… S-Seonghyeon… what is it…?"
"Before we start the massage later, there's something I want to talk to you about a little seriously…"
"A serious… talk…?"
"It's nothing that heavy — how do I put it… something came up that has me a bit worried, as a friend. Anyway, want to hurry up and finish showering? We've been in here too long."
"S-should we…? Yeah… shower, we should shower…"
"Oh, right — once you're done, you can put clothes on up top, but down below, just come out in panties, okay?"
"Just panties?!"
"Not the ones you usually wear — I've got some I bought for members. I'll head out first and leave a pair in the changing area."
"O-okay… I'll put those on…"
"I'll lock the dojang door so nobody else can come in, so don't worry."
"Yeah…"
Lee Yena's head was spinning.
He'd casually stroked her pussy with his finger without a word, stared at the juices coating it, then suddenly said he had something serious to discuss — and after the shower she was supposed to come out wearing only panties down below…
It was all incredibly dizzying.
What could it be…? Is there something wrong with my pussy… with the… wetness? He said it wasn't anything serious… something that has him worried as a friend…?
She didn't suspect Ju Seonghyeon. She didn't question his inexplicable behavior. She simply turned his words over in her mind — the words of a friend who seemed genuinely concerned for her.
…I should wash up and get out there. I'm curious.
And with that, she hurried to finish her shower.
After washing herself clean for the massage, she pulled on the white cotton panties Ju Seonghyeon had set out and stepped into the dojang.
Following his lead, Lee Yena sat down on the slightly low massage table — and then he asked:
"Yena, have you by any chance… built up a lot?"
"…Huh? Built up what?"
"You know… sexual frustration."
"……!!"
From her proud, trustworthy friend, she received the single most shocking question she had ever heard in her life.
