Positive Reactions
Can you stop calling me a slut...
Despite her usual strong image, she looked fragile and pathetic right now.
"Why are you like this when you have such a beautiful body?"
Tae-seok's hand kneaded her breasts even harder.
"Being pretty isn't everything... You know how I've been living lately... Haaah~"
Her words cut off as he suddenly drove into her with force.
At the loud moan that slipped out involuntarily, she clapped a hand over her mouth.
"But... can we really not do it inside? Hngg~ I... I want to scream as loud as I want..."
Eun-su pleaded in a low voice, still glancing around nervously.
She was on edge, terrified that someone might hear or that a passerby might look up from the street.
That very anxiety made her heart race even faster.
"You can scream. I don't mind."
"You're crazy... Haang..."
Tae-seok thrust into her wildly from behind.
The slow rhythm from earlier had vanished.
Now it was rough, fast, and violent.
Slap.
Slap.
The sound of flesh colliding carried through the quiet dawn air, spreading farther than it should.
"It feels amazing for me too... but my heart is pounding so hard I'm losing my mind."
Eun-su gripped the railing even tighter.
"Did your breasts get bigger?"
Tae-seok asked as his fingers gave her nipple a light pinch.
It was so stiff the hardness showed even through her crop top.
"I switched to a D cup... but it's already filling that completely."
Tae-seok let out a short laugh at her answer.
"Definitely satisfying to play with."
His hand enveloped her breast completely.
The way it filled his palm—soft, yet springy with perfect elasticity. It was clearly larger than before.
"Later, give me that bastard's channel name."
"Why?"
"I ought to know who the guy is that's been fucking my woman like that."
The moment the words left Tae-seok's mouth, Eun-su's heart slammed against her ribs.
It wasn't mere physical stimulation.
Even though he spoke so casually, she felt strangely bound by his claim.
"Your woman? Earlier you said we weren't anything."
"That's just how I phrased it."
Hearing him call her "my woman" made Eun-su's pulse race even harder than before. It was an entirely different thrill from the pleasure she felt when their bodies connected.
After her orgasm tightened around him, Tae-seok carefully withdrew from inside her.
"Now... let's go back to the room."
Relief finally washed over her face at his words.
"Thank you. Once we're inside... I'll make it really good for you."
Not long after Do-hyun uploaded his YouTube video, strange momentum began to build.
At first, it followed the usual pattern.
Views climbed slowly. A handful of comments trickled in.
It looked like another ordinary workout video, nothing special.
But roughly an hour after upload, the graph shifted noticeably.
The view-count curve suddenly steepened.
Do-hyun initially dismissed it as a fluke. Traffic sometimes spiked at certain times of day.
The real problem came next.
Audience retention.
Instead of dropping in the middle as it usually did, the graph was climbing again in specific sections.
"...Huh?"
Do-hyun narrowed his eyes and clicked on the segment.
Three minutes and forty-two seconds.
It was the moment Eun-su settled into a squat and lowered herself.
The loose crop top rode up, revealing her abs, and the graph spiked hard.
The play of light across her stomach with every breath, the elegant line of her waist, the sharp angle of her toned pelvis— even he had to admit her figure stood out.
He immediately opened the comment section.
As time passed, the comments grew bolder.
Do-hyun acted immediately.
He updated the video description.
→ “Kim Eun-su Trainer Instagram Inquiries: (link)”
→ Club location added.
He also changed the thumbnail from a generic workout pose to the shot that best showcased Eun-su’s abs.
The view count didn’t simply rise—it exploded.
Ten thousand.
Twenty thousand.
Before the night was over, both comment count and likes had surpassed the average of his previous videos.
The next morning, the phone at Eun-su’s fitness club wouldn’t stop ringing.
It started with one or two calls.
Then ten.
Soon it was completely overwhelming.
"Is this the place where Trainer Kim Eun-su works?"
"I saw the video and wanted to get in touch..."
"Can I sign up for PT right away?"
Only then did Eun-su realize what was happening.
So Do-hyun’s video went up.
At that moment, Do-hyun himself showed up at the club, breathing a little hard.
"Noona."
He didn’t waste words.
He simply shoved his phone in front of her face.
"This… it looks like it actually blew up."
The screen showed real-time view counts climbing, an endless flood of comments, and nonstop notification alerts.
Eun-su stared at the screen in silence.
Then she murmured very quietly.
"...It was this much?"
"The reaction is completely insane. Noona, the view count already passed my channel average. In just three days..."
"Yeah… that’s good."
"Good? This is way beyond good. It’s completely exploded."
He couldn’t hide his grin as he continued.
"You’ve been getting tons of calls at the club too, right? I put every link up there."
"Yeah… it’s about three or four times more than usual. I had no idea what was going on."
"Noona… let’s upload videos together regularly. Only an idiot would let this kind of popularity go to waste."
It was an ordinary morning at Eun-jung’s house with the two sisters.
After starting the day with morning sex with Eun-jung, the three of them sat together for breakfast and coffee.
Tae-seok naturally kept his arm around Eun-su’s shoulders, casually groping her body as if it were the most normal thing in the world, while Eun-jung sat across from them.
She watched them with the relaxed composure that came from having already been given several orgasms by Tae-seok, slowly sipping her coffee.
Eun-su, too, seemed to accept the situation as natural even in front of her older sister.
Eun-su spoke first.
Her voice was slightly breathless from the way Tae-seok was fondling her breasts, yet the topic was serious.
"I’m thinking about starting a YouTube channel."
Eun-jung set her coffee cup down and looked up.
Her expression barely changed—nothing more than a mild “Oh? That sounds fun” from someone with no particular interest in the field.
"Really? Fitness-related?"
"Yeah… Do-hyun said he’d help a bit."
Eun-jung nodded and returned her gaze to her coffee cup.
Tae-seok looked at Eun-su’s face.
While he continued to slide one strap of her tank top down, exposing half her breast and kneading it openly, he asked, "A YouTube channel? What kind of content?"
Eun-su’s breathing grew heavier from his persistent touch, yet she organized her thoughts and continued.
Her plan wasn’t very different from other fitness YouTubers.
Filming herself working out at the club she ran, home training routines people could do at home, diet management, sharing exercise programs. Occasionally mixing in daily vlogs to communicate with viewers.
It was typical, but also the most stable approach.
"Well… just normal stuff. Showing myself exercising, sharing bits of my daily life. The things people are curious about… that sort of thing."
Eun-su finished and waited for Tae-seok’s reaction.
"Isn’t that too standard? Though I suppose a lot of people would be satisfied just staring at your face and body..."
Eun-su’s brows furrowed slightly.
But Tae-seok ignored her reaction and kept speaking.
"What I’m thinking… how about content that turns ordinary, plain women beautiful?"
Eun-su tilted her head.
"Ordinary women? How?"
Tae-seok squeezed her breast firmly as he answered.
"Show them doing moderate training, then bring them to me. I’ll make them beautiful. You know what I can do."
Eun-su’s eyes widened.
She understood his meaning instantly.
She knew exactly what “make them beautiful” implied when it came from Tae-seok.
"That’s… what..."
"If you don’t like it, forget I said anything."
Tae-seok was indifferent, as if he had simply thrown out an idea and she could do as she pleased.
Eun-su fell silent for a moment.
It was certainly a concept with strong appeal—something no other YouTuber was doing, a completely unique angle.
But the method didn’t sit well with her.
The thought of having to introduce other women to Tae-seok made her bite her lip.
Watching her, Tae-seok added one more thing.
"By the way, noona."
"What?"
"If that scumbag Do-hyun is going to help you… does that mean you’re giving him your body again?"
The way he asked while roughly gripping her full breast was completely blatant.
Eun-su’s face flushed red.
"That’s… just..."
"Just? You’re going to make the same kind of deal again? Sleep with him once for filming help, sleep with him again for editing… is that it?"
Eun-su couldn’t deny it.
She had already expected that if she asked Do-hyun for help, that kind of transaction would naturally follow.
"Well… if that’s the choice you’re making, I won’t criticize you. Using your body to avoid spending big money is fine. You can’t ignore the know-how of an already successful YouTuber."
"Do you really not care at all if I do stuff with other guys?"
"Why? Do you want me to interfere with every little thing?"
"I don’t know… It still feels awful."
Eun-su couldn’t continue.
As Tae-seok was about to step out of Eun-jung’s front door, he heard strained grunting from the staircase.
His gaze shifted in that direction.
A woman carrying a rather large box was struggling to climb the stairs.
It was Kim Su-yeon, the new tenant who had just moved in.
