Chapter 18: Sex Points (SP) Are Generated.
“Trainer…”
The look in Heo Da-young’s eyes as she watched me had changed.
“M-Ms. Heo Da-young?”
“It’s all built up, isn’t it?”
“Pardon?”
“Fatigue. It’s built up in you too, Trainer.”
“Now, hold on a second, ma’am.”
“It’s only natural that sex relieves fatigue. Don’t you agree?”
Heo Da-young approached me, swaying her body provocatively to seduce me.
“You’re just brimming with exhaustion, aren’t you? Look at how hard your arm muscles are…”
She traced her fingertips down my arm.
Thanks to the workout I’d done before she arrived, my pumped muscles were indeed rock hard. Even though they were barely there to begin with, to Da-young—who was already under the gym’s hypnosis—they likely looked more well-defined than any other man’s.
“Ugh.”
The touch of a woman was unfamiliar. It was far too stimulating for me.
Naturally, blood rushed downward, and that surge caused my lower half to stiffen.
“It looks like this part of you is tired too, seeing as it’s gotten so hard.”
She leaned in and whispered into my ear. Every time she spoke, her warm breath tickled me. Her voice, thick with moisture, had a strange, resonant quality to it.
“W-wait a minute. Ms. Da-young…”
I reached out to push her away. But of all things…
“Ah, you’re quite the naughty one.”
My hand, intended to push her back, landed squarely on her breast. I squeezed it instinctively at the soft sensation.
“Haaah!”
Wow, it’s really soft.
Is this what a breast feels like? It was a level of softness on a completely different dimension from squeezing a butt.
“Gasp.”
I inhaled sharply without realizing it.
Gulp.
“Your fingers are moving so lewdly over my breast, Trainer.”
Da-young covered my hand, which was still gripping her chest.
“Do you know something?”
“I-I’m not sure.”
“Every time you touch me like this, my heart beats like this.”
Thump, thump.
The sound of her racing heart traveled through my hand.
“If just touching like this relieves fatigue… I wonder how much more would be relieved if we actually had sex?”
Da-young smiled. The seductive smile of a woman in her late twenties was not something twenty-four-year-old Jae-ho could withstand.
“Well, you see…”
Strength left my hands. I had to pull away. I knew I had to.
But the strength just wouldn’t come. No, it wasn’t that I lacked strength. Da-young’s grip was so powerful that I couldn’t overcome it. Where was she getting this kind of strength?
“Did you know? They say a person pouncing on someone for sex can exert seven times their usual strength.”
“Ma’am, you shouldn’t do this.”
Then, Da-young pushed me. I couldn’t resist the force and was shoved backward. After pinning me down and climbing on top of me, she licked her lips.
“Let’s relieve each other’s fatigue, Trainer.”
She began to strip me. All I was wearing was spandex gym wear. As the clothes came off, my body was revealed.
“Oh my, your skin is so fair.”
I was past the point of being able to persuade her with words.
‘If that’s the case, then I might as well…’
I had to go with the flow. I grabbed Da-young’s waist as she sat atop me. I kneaded her waist and hips as if giving a massage.
“Haaah… So you’re finally in the mood.”
Da-young trembled at my touch.
“We have to relieve that fatigue, after all.”
Ultimately, to increase the number of members and raise the gym’s level, I needed regular clients. That meant I had to maximize their satisfaction.
‘I’ll give the member the service she wants.’
Since I couldn’t avoid it, I might as well enjoy it.
“I didn’t think you were interested in this sort of thing, Trainer, but I guess I was wrong.”
Da-young laughed, and I followed suit. I smiled as I removed her clothes. I saw her bare breasts that had been hidden beneath her top. They were large yet perky, and their perfect shape stimulated my lust.
‘She wasn’t wearing a bra?’
“Are you surprised? I didn’t put one on because I wanted to get to my workout quickly.”
“Is that so?”
“Do you prefer it if I wear one?”
“No! I-I like it like this!”

I liked it far too much. To think such beautiful breasts existed.
“Then let’s loosen up that body that’s gone stiff from fatigue.”
I pulled off Da-young’s pants. She, in turn, stripped off mine. We stood there, exposing our most private parts to one another. My face flushed with embarrassment. Da-young’s face was flushed too, though likely for a different reason.
“Would you like to take a position?”
At my words, she climbed on top of me.
“Like this?”
Straddling my stomach so we were eye-to-eye, a blushing Da-young reached behind her and gripped my cock. The view was obscured by her body, but I could feel how delicately she was handling it.
“Y-you’re very good at that.”
“I’m always sincere about everything I do.”
“I see.”
“You should massage me too, Trainer. My breasts feel a bit sore.”
If they were sore, I had to soothe them. I reached for her breasts. Once again, I felt that squishy, soft texture.
“Haaah…”
I felt the blood rush to my face. My breathing grew ragged. Combined with the meticulous movements of Da-young’s fingers on the tip of my cock, my entire body began to shake. All my nerves were so focused on my crotch that I could barely even feel that I was touching her breasts.
“You really were exhausted, Trainer… to be this hard. My nipples are getting just as hard too…”
She definitely didn’t have this kind of image when we first met. Was this a hidden instinct?
Da-young, who had been teasing my member with her fingers, gave me a faint smile and a wink. Then, she lifted her hips. Keeping my cock steady with her hand, she lowered herself down.
Da-young’s dripping wet pussy enveloped my cock. The tight squeeze of her soft yet firm walls awakened my already sensitive member. The pleasure starting from below jolted every sense in my body.
Pop! Pop! Bang!
“Hngh!”
The moment I entered her, pleasure exploded in my head like fireworks. My pupils dilated, and my mouth hung agape. I took a deep breath. For a moment, my consciousness drifted as if I had stepped into another world and back.
At the same time…
“W-wait…”
Semen surged up from below. I wanted to hold it back somehow. I wanted to enjoy this sensation longer. I felt foolish for having been so passive and trying to avoid this. I desperately wanted to hold back the ejaculation.
However…
“Ugh!”
My cock twitched. Semen poured out. I had ejaculated the moment I inserted it.
I was mortified. More than the act of ejaculating itself, I was embarrassed that I couldn’t even last the moment of penetration.
“Oh? Trainer, was this your first time?”
Da-young seemed taken aback as well.
“I’m sorry.”
Overcome with shame, I covered my face. It was then that Da-young pulled my hands away. She was looking at me with gentle eyes.
“It’s okay. Everyone has a first time. If ejaculating is the problem, we can just make it stand up again.”
Then, she kissed me.
“Was that your first kiss too?”
“Yes.”
“Then make it stand up again.”
Da-young giggled.

“Haah, haah…”
The bodies of the man and woman intertwined. Jae-ho swung his hips while holding Da-young’s legs wide apart. Seated on the Butterfly Machine, Da-young let out a thrilling moan every time Jae-ho’s hips thrust forward.
Before they knew it, they were both completely immersed in the sex. Though his movements were the clumsy thrusts of a virgin, even that seemed cute to Da-young.
‘This feels so good.’
How could it feel this good? His hip movements were clearly unrefined. Yet, every time he swung his hips and thrust his cock deep inside, her head spun. Intense pleasure stimulated her waist. It was an excitement she had never felt when being with other men.
Even self-proclaimed ‘sex masters’ hadn’t been able to give her an orgasm like this. And yet, she was feeling this level of climax from Jae-ho, who had just graduated from virginity?
Was this what they called sexual compatibility?
But wait, why was she having sex with this man? She had clearly come here to exercise and relieve fatigue. Why?
‘Why else? It’s only natural to have sex to relieve fatigue.’
Especially sex with a trainer. She had been so stressed and tired lately; this was a relief. Every time Jae-ho thrust his hips, she felt her accumulated fatigue melting away.
‘Yes, this is it. Fatigue is relieved so well this way.’
She thought it was strange for a second. Was it because she was so tired? She felt like she needed to have sex even more vigorously. Moans escaped her lips involuntarily.
“Haang! A-aren’t you a bit too good at this?”
“Am I?”
“Yes, it feels so good—haaah!”
Da-young’s body shuddered. The squirting fluid that poured from her lower half drenched Jae-ho’s body.
“You’re quite skilled.”
Da-young looked up at Jae-ho as he moved his hips above her. She wanted to sleep with this man more. Every time his cock raked through her insides, she felt her body grow lighter alongside the pleasure.
It felt amazing. Beyond simple pleasure, she felt refreshed. She was feeling a desire for Jae-ho that she hadn’t even felt for the popular Assistant Manager Jung at her office. He even started to look adorable to her.
Da-young reached out.
“Hold me.”
“Understood.”
Jae-ho pulled her into his arms, feeling her skin against his. Every time he inhaled, the scent of Da-young’s sweat filled his nose.
“You like it when I do this, right?”
She had reacted well when he pulled her waist close and thrust suddenly. She had trembled and let out a violent moan.
‘She was even flailing her feet.’
I snapped my hips forward.
“Haaahng! Trainer!”
Da-young, who must have reached orgasm several times by now, clung to Jae-ho’s body, shaking uncontrollably. The sensation of her breasts against me was vivid.
Slap! Slap! Slap!
The sound of flesh hitting flesh echoed through the living room.
“Hraaaaaah!”
The moans of Da-young, held in Jae-ho’s arms, grew louder and louder. And then…
For the first time, she realized that a person could actually faint from pleasure alone.
*
We continued to explore each other’s bodies until the early morning. There was no time limit on sex meant to relieve fatigue.
As the sun rose and it became time for her to head to work, Heo Da-young changed her clothes.
“Well then, I’ll be going now.”
Having changed back into her office look, Da-young spoke in the same calm voice she had used when she first arrived. Had the gym’s hypnosis worn off? Her polite greeting was as formal as could be.
Of course, the way her eyes briefly flickered toward my crotch was probably just my imagination.
After she left…
“Whew…”
I wiped away my sweat and let out a long sigh. It had been a whirlwind of a day. I never imagined I’d lose my virginity like this.
Just as I was about to tidy up the living room and head to bed…

The Sex Shop?
I was suddenly wide awake.
