"Then, I'll head back. See you in a bit, Oppa."

"Okay, go quietly so you don't get caught."

"Okay!"

It's early morning, and Yeonji quietly returns to her room without being caught by her mother-in-law.

'Well… she's already caught me, though…'

Yesterday, my mother-in-law kept pretending to be asleep, but she already knew that Yeonji had come to my room.

She made various excuses to keep Yeonji and me from meeting often, but it doesn't seem like she genuinely intends to stop us.

"Hoo… Should I sleep a little more…"

It's still 6 AM, a bit early to start the day.

Besides, now that I'm unemployed, I have even more time, so there's no need to start the day early.

"No… I might as well go for a jog since I'm already up."

If I get too lazy, my body might break down later.

Since I'm already up, I decided to change into my workout clothes and go outside for a run around the mansion.

"Huh? Ms. Yeonhee?"

"…Good morning, Juhyun-nim."

As I was stretching outside, someone appeared behind me. When I turned to look, it was Ms. Yeonhee in workout attire.

She seemed a bit surprised to see me, her eyes widening slightly, but she quickly returned to her usual expression,

her face turning expressionless as always.

"What brings you here at this hour?"

"Ah… I woke up early and thought I'd go for a jog… What about you, Ms. Yeonhee?"

"Yes… I make it a routine to jog every day."

"Really? That's amazing."

"Thank you… Then."

After a brief greeting, Ms. Yeonhee started running to begin her jog.

'Hmm… I should follow her and learn the jogging route.'

I kept a certain distance so as not to disturb her and followed behind.

'Just running around the house is making me quite breathless…'

It was just a lap around the mansion, but it was quite tiring, making me breathless.

It's not that my stamina is low, but rather that the house is that big.

Living in a place like this is amazing, and it still doesn't feel real.

As I was jogging while lost in thought, the distance between me and Ms. Yeonhee started to close.

'Am I too close?… But this is quite…'

Maintaining a distance of about 10 meters, I was drawn to Ms. Yeonhee's back as I jogged.

She was running in tight leggings and a loose tank top.

Naturally, her firm buttocks caught my eye.

'She's not at all inferior to my mother-in-law or Yeonji…'

It's a bit shameful, but as a male, I couldn't help but be captivated by her swaying buttocks.

'And those breasts are just unfair!'

What's worse, her large breasts, visible from behind, were bouncing with every step she took.

Whether she wasn't wearing a bra or not, her large breasts were bouncing greatly.

Even compared to Yeonji and my mother-in-law, they were only slightly smaller, and their size was evident even from behind.

I continued jogging, following closely behind Ms. Yeonhee, and finished by running several laps around the mansion.

"Haa… haa… haa… You run well."

"Hahaha… You too, Ms. Yeonhee…"

I sat down on the steps in front of the entrance, exhausted, leaning forward.

Honestly, I had enough stamina to run a few more laps, but I couldn't get up because of the current situation.

'I can't get rid of this erection!'

Thanks to Ms. Yeonhee's alluring figure, I had unknowingly gotten an erection while running.

It was quite large, and since I was wearing thin clothes for jogging, it would be obvious if I stood up. So, I just sat there,

pretending to be exhausted.

"Are you alright?"

*Jiggle*

"Y-yes, I'm fine… hahaha…"

She's blunt, but her personality is kind, so she came over to check on me, but every time she did, my dick just got harder.

'I need to hold it down with my hand…'

"I'll go get some water, so please wait a moment."

"Ah… yes, thank you."

Ms. Yeonhee, thinking I was truly exhausted, went inside to get water.

In the meantime, I started singing the national anthem in my head to calm down, and it slowly started to work.

'If I sing it three more times…'

"Here's some water."

"Ah… thank you."

"Gulp… gulp… gulp…"

I was just starting to calm down, but Ms. Yeonhee came back faster than I expected.

And then, she was drinking cool water right in front of me.

'The, the way it's flowing… gulp…'

I couldn't even think about drinking water, my eyes glued to the scene in front of me.

The water Ms. Yeonhee was drinking flowed down her neck, soaking her thin tank top.

As the water droplets fell, the clothes that were slightly see-through from sweat became even more transparent.

"Gul…p"

Slowly, Ms. Yeonhee's nipples became visible.

As her light pink nipples, similar to Yeonji's, became visible, I swallowed hard and stared.

"Hoo… What… Ah."

"…Ah! Th, that's…"

Ms. Yeonhee, noticing my gaze, lowered her head, and her eyes fell upon her chest, where her nipples were visible.

"…I'll go inside now."

"M-Ms. Yeonhee, that's…!!"

I tried to make an excuse, but Ms. Yeonhee went inside without looking back.

'Damn it… she's probably going to think I'm a pervert…'

I was staring so intently that there was no way to make an excuse, so she would definitely think I'm a pervert.

Still, she's like an older sister to Yeonji, so she's like a sister-in-law to me.

If I get labeled as a pervert by such a person, and if she tells Yeonji or my mother-in-law, it could be a problem.

'I need to clear up the misunderstanding later…'

There's no point in going after her now, so I decided to resolve it later.

My erection had subsided, so I went back inside, feeling like I had woken up early for nothing.

...….

'I was too careless…'

Yeonhee, who had returned home, had a noticeably flushed face, unlike her usual self.

She usually has a blunt expression and a chic aura, but now she was flustered and didn't know what to do, experiencing something

for the first time.

She had gone out for her daily jog and encountered Juhyun, but she didn't pay much attention to it.

She jogged as usual, but because it was such a familiar routine, she didn't pay much attention to her attire.

She jogged in her usual light clothing, and her chest, wet with sweat and water, became see-through, and Juhyun had seen it.

'That kind of gaze… it's the first time I've received it…'

She was already used to receiving lustful gazes from men.

Thanks to her natural beauty and figure, it was natural for her to be popular.

She was so used to the dirty gazes of men who tried to take advantage of her that she didn't even care anymore.

However, the gaze Juhyun showed today was a little different.

"It was primal… that kind of gaze is a first…"

Of course, it was because she had been careless, but Juhyun had sent her a surprisingly honest male gaze.

It was so honest that it almost felt pure.

'And… it was huge…'

Normally, Yeonhee wouldn't hesitate to get angry, but she couldn't get angry because it was her own fault.

And because of Juhyun's erection.

"I thought his pants were going to rip… are men usually that big?"

She was popular, but she had no interest in dating or marriage, so she had never dated anyone.

Naturally, her interest in men had gradually faded, and she only had basic knowledge of sexual matters, not detailed knowledge.

But then, she saw a man's erection for the first time.

Seeing Juhyun's erection while looking at her made her even more flustered, and she quickly left the scene without even having

time to get angry.

'It's not… that unpleasant, maybe…'

*Thump thump thump*

She didn't know what she was feeling, but she felt her heart beating fast at Juhyun's pure gaze (?) and the sight of a man's

erection for the first time.

To clear her head, she quickly went to take a shower.

.....

"Then, I'll be off, Mom, Oppa."

"Okay."

"Have a good day, Yeonji."

After having breakfast together, Yeonji went to school first.

As my mother-in-law and I saw her off, Yeonji smiled brightly, looking happy.

"Then, I'll take the young lady and then go to the company to take care of some work."

"Okay, have a good day, Yeonhee."

"Yes, Madam."

"Uh… um, have a good day."

"…Yes, Juhyun-nim."

It felt a little awkward when I said goodbye, but Ms. Yeonhee didn't seem to mind, answering calmly as usual.

'Is that a relief?…'

I was worried that she might tell Yeonji or my mother-in-law everything, but I was relieved that Ms. Yeonhee seemed to have moved

on from it more coolly than I expected.

"Then, shall we have some tea inside… Master♥?"

"U-um… yes, Mother-in-law."

As soon as the two of them left, my mother-in-law, as if she had entered slave mode, walked with me, clinging to my arm with a

lewd smile.

'It feels completely normal now.'

"Come to think of it, last night…"

"Last night, I was asleep the whole time, so I don't know what happened♥."

"…Really?"

"Yes♥."

My mother-in-law pretended not to know about the intercourse from last night and smiled playfully.

There was no need to bring up the topic any further, so I stopped talking and headed to my mother-in-law's room.

"Come to think of it, I saw you jogging this morning… Should I buy you a treadmill or some exercise equipment?"

"Huh? No, just running is enough."

If I said yes, she would definitely create a home gym that would put any gym to shame.

'Even if I bought something like that, I probably wouldn't use it often and it would just be left to gather dust…'

I had built up my stamina and body through my delivery job and simple exercises, but I didn't enjoy exercising, so it was

unnecessary.

"Hmm… Really? But you must have been a little disappointed this morning."

"Huh? Disappointed? What do you mean?"

My mother-in-law, suddenly wearing a playful and lewd smile, sat next to me.

"Well, you had an erection like that, but you didn't get to cum even once… while looking at our Yeonhee♥."
