Chapter 55—A Week-Long Ban!

"Oppa, you're back!!"

"Welcome back from hospital~ Are you hurt anywhere?"

"Nope!"

A day had passed since they returned home, and Yeonji and Yeonhee were also back.

Thankfully, there were no issues with Yeonji's health, but the doctor had scolded her for having hardcore sex, saying it could harm her body. Yeonji seemed quite embarrassed about it.

'I should keep the fact that I slept with my mother-in-law a secret…'

After our outdoor sex walk, we naturally showered together and slept in my room. I didn't notice anything unusual until I woke up.

'I need to be more careful…'

Yeonji and Yeonhee weren't home yesterday, but I had been too careless, showering and sleeping in the same room as my mother-in-law.

If Yeonji had seen us, I might have come up with an excuse, but if Yeonhee had, it could have caused serious trouble right away.

"But… the doctor said no sex for a week…"

"Huh?… Oh.."

Yeonji's voice was barely audible, but the disappointment in it was unmistakable.

'She's just starting to awaken to these sex desires, and now she has to wait… No wonder she's so disheartened.'

"Waaaaah…"

I felt disappointed too, but considering Yeonji's health, it was a necessary decision. However, she was so upset about not being able to be with me for a week that she even teared up.

"Did this son-in-law make Yeonji cry?"

Stare…

"N-no… It's… it's not that…"

My mother-in-law smiled slightly, clearly teasing, but when Yeonji actually started crying, Yeonhee shot me a sharp look.

"Hehe… I'm just kidding. Yeonji, there's no need to cry like that. You should get ready for school."

"Huh? But I just got home?"

"This girl… You're perfectly fine, and the first thing you think about after coming home is having sex with this son-in-law? You seem fine to me!!" 

"M-Mom!"

Yeonji's face flushed at the word "sex" and she yelled at her mother.

'Yeonhee seems weak to this kind of talk.'

Yeonhee, who had been standing quietly beside us, was even more flushed than Yeonji but tried to keep her composure despite her embarrassment.

"Alright! If you're healthy and not having sex, go to school!"

"Okay, okay, just stop saying 'sex, sex'… Waaaaah…"

Flustered, Yeonji ran upstairs to get ready for university.

"Hehehe, she's so cute♥"

My mother-in-law smiled, clearly pleased with her daughter's embarrassed reaction.

'When mother-in-law acts like this, she seems like a sadist… Could it be…'

Unlike the masochistic female appearance she shows when we're alone, my mother-in-law seemed a bit S-like.

'But Yeonji was like that during her first time, so is it really that embarrassing to be embarrassed by the word "sex"?'

Yeonji's embarrassment trigger was a bit unpredictable, but since I enjoyed seeing her flustered, I chose to stay quiet.

"Then, please take care of her, Yeonhee."

"Yes, Madam."

My mother-in-law looked slightly disappointed at being called "Madam" but she seemed accustomed to it, merely watching Yeonhee leave.

"Haa… that child used to follow me around calling me 'Mom' when she was little…"

"Yeonhee? … I can't picture that at all."

"Oh my, when Yeonhee was little, she was even more of a crybaby than Yeonji… at least until she found out we weren't blood-related…"

My mother-in-law smiled fondly at the memory, though there was a hint of regret in her expression over how things had changed.

"Yeonhee will… call you 'Mom' again someday."

"I hope so… just like you, Master♥"

"T—that's…"

I blushed slightly, embarrassed by the sudden remark.

"Hehe… You must be tired from staying up late last night, so get some rest. After lunch, I'll tell you more about what I mentioned before."

"Ah, yes. Thank you, Mother-in-law."

I had spent about two hours mixing bodies with my mother-in-law after returning home from our outdoor exposure walk, so I was a bit tired.

Being considerate of my mother-in-law, I saw Yeonji off to school before heading to my room, planning to take a nap.

.........

[POV Change]

"Mom is really too much…"

"Madam didn't mean any harm."

"I know, but still… How can she say 'sex.. sex' so openly...?"

Yeonji was talking to Yeonhee in the car on the way to school.

She was still blushing as she talked about what happened at home, seemingly embarrassed.

"Madam probably didn't think you were a perverted daughter who only thinks about sex."

"...…"

"Miss?"

As expected of Yeonji, who wasn't good at lying, she couldn't deny Yeonhee's accurate statement and just avoided her gaze.

"Could it be that you really…"

"N-no!! Anyway, I'm going to school. See you later, Yeonhee!"

As soon as she arrived at school, Yeonji hurried out of the car and rushed to her lecture, almost as if she were fleeing.

"Hi, Sujeong."

"You're here?… But why are you sweating so much?"

"U-uh… It's nothing, hehe…"

Sitting beside her best friend, Sujeong, Yeonji focused on the lecture, trying to act natural.

......…

During lunchtime, they ate at a fancy restaurant near the school that Sujeong had reserved. Yeonji hesitated before bringing up a delicate topic.

"Um… Sujeong."

"Yeah? What is it?"

Sujeong was eating pasta with an air of elegance, making Yeonji feel a little envious, as it reminded her of the image of the kind of woman she aspired to be.

"Um… You've had se—sex… right?"

"Pffft?!"

"Are you okay?"

"Cough! Cough! I-I'm fine!"

Sujeong, caught off guard by the sudden question, choked and coughed, her face flushing red. It was hard to tell if the redness was from the question or from the coughing.

'S-suddenly talking about sex… I haven't even done it once yet…'

She felt envious that Yeonji had become a woman before her by actually having sex recently.

But she never expected Yeonji to ask such a question, so Sujeong was flustered, but she soon put on a relaxed expression and answered.

"O-of course… It was a little while ago, though…"

"Really?… I wanted to ask you something because of doing it with oppa…"

Yeonji was equally embarrassed, her face turning red as she spoke. However, she seemed to be troubled by something, so she hesitated for a moment before continuing.

"What would it be like… if you couldn't have sex for a week?"

"A week? You can just hold it in."

"W-what if it's hard to hold it in?"

"It's just a week… Are you worried about not being able to have sex with your oppa for a week?"

".....Yeah."

Sujeong was stunned to see Yeonji nod her head in agreement, even though she hesitated a little.

'Y-Yeonji was this kind of girl?!'

The Yeonji that Sujeong knew was a pure girl who would blush just from watching porn and couldn't even look at it properly, let alone talk about anything sexual.

'She's worried about not being able to have sex for just a week?! What did that oppa do to Yeonji?!'

Sujeong thought that the reason she had changed into such a sexual woman was because of that oppa, and she was shocked inside, but she pretended to be calm and continued to speak.

"You… can't hold it in for a week?"

"N-no, I can hold it in… but it might be hard for oppa to hold it in too… and I also want to do it… Oppa comes first, though…"

Yeonji stammered as she spoke, making excuses about her oppa, but it was clear she was indirectly saying that it was difficult for her to wait for a week.

'I wouldn't know since I haven't done it…'

Sujeong had lied to Yeonji, pretending she had experience with sex, but in reality, she had no actual experience.

"But why can't you wait for a week? Is your mom stopping you? Or is oppa somewhere else?"

"No, it's not that…"

Sujeong asked, attempting to change the topic.

Yeonji's face flushed bright red. She looked around nervously before whispering the reason in Sujeong's ear.

"Whaaaaat!?! So you were too intense…!"

"Shhh!!"

Sujeong was so shocked that she nearly shouted, but thankfully, Yeonji covered her mouth just in time, preventing anyone else from hearing.

"L-let's go somewhere quiet first."

"Okay…"

Due to Sujeong's near outburst, they had become the center of attention. So, they decided to change locations and headed to a café they often visited to continue their conversation.

"S-so you're saying you were too intense and it put a strain on your body?!"

"Yeah… that's right."

"No, how did you do it…??"

She couldn't understand how a normal couple could have sex so intensely that they were told not to have sex for a week.

'C-could it be that his dick is really as big as an arm?!'

She had thought Yeonji was exaggerating a little last time, but considering Yeonji's situation and condition, she could tell it wasn't a lie.

"H-how did you do it to get like that?"

"Th—that's a secret~"

There were many things too embarrassing for Yeonji to discuss, even with her best friend, so she chose not to tell Sujeong.

However, the more Yeonji withheld, the more curious Sujeong became.

"Anyway, if the doctor told you to rest, you should rest, okay?"

"Yeah… but…"

Sujeong was quite shocked to see Yeonji subtly revealing that she wanted to have sex despite what the doctor said.

"W-well, the auntie would know best about that kind of thing, so why don't you ask her? Of course, I can tell you too, but it seems very different from my case…"

"Really? Okay, thanks for the advice, Sujeong."

"No… It's nothing…"

In the end, Sujeong couldn't come up with a solution, so she simply passed the responsibility back to Yeonji's aunt.

'How intense did they have sex to be to hurt their body… I'm jealous…'

Sujeong was envious that Yeonji's boyfriend was getting closer and closer to her ideal type, but she didn't say it out loud since he was her friend's boyfriend.

She just felt her panties getting a little wet as she listened to Yeonji's story, feeling envious inside…
