Chapter 151 – Swimming Pool Plan

“Oh, that’s right. You said you can buy swimsuits before going to the pool? With this card, the three of us can go out together and buy them.”

I handed her card to her mother, who held her arms wide open.

“Oh no~ We can buy enough with our money. We still have a lot of left over from what we received in cash~”

Her mother seemed happy. The way she smiled brightly and spoke without any worries made me feel like I was looking at my older sister. In the end, Mom backed out without taking her card.

“Tell me later if you need it”

“Hehe~ Thank you, son~”

It’s late in the morning, not yet lunchtime. I was leisurely spending time at home using the air conditioner.

“Mom. Su-a is probably studying, right?”

Su-ah’s door was always closed, so you couldn’t tell just by looking at her whether she was studying or sleeping.

“I made breakfast, but I guess I ate it after working out… Hmm… I guess I’ll be studying now? I’ll be busy because the mock exam is less than a month away.”

Her mother would convey the message to Su-ah to go buy her clothes. It’s been a while since I’ve been doing anything at home, so I felt somewhat bored.

‘Still, it will be quiet while I’m there’

“Mom, wait a minute”

I motioned for her mother to come closer to me from the table.

“Huh?”

Mom leans her upper body towards me and puts her face close to me. Her white short-sleeved tee supporting her mother’s massive breasts and her apron wrapped once more around it.

Sarak-

I pulled the straps of her apron around her mother’s neck and undid them. Mom smiled, and she quietly watched what I was doing.

“It left a mark on her neck”

She’s not on a leash now, but yesterday’s leash play left marks from the dog collar on her mother’s pale neck. Yesterday’s events come back to mind, and the situation that conquered her mother comes to mind again.

“You played a novel game yesterday, hehe~”

Mom must have known exactly where I was looking. She rubbed her neck and made an embarrassed noise.

With her apron undone, the mother was left with only a white short-sleeved t-shirt that showed through her underwear, as if she were wearing see-through clothes.

“I can see everything”

“That’s why I was wearing an apron…”

I reach into her mother’s short sleeves and pull the shoulder straps of her gray bra down her arms.

“Oh my…”

One of the mother’s breasts cannot overcome the weight and goes down slightly.

“Stay like that to see how Su-ah reacts during lunch.”

I was curious about how Su-ah would react if exposed to a situation where her mother’s breasts were defenselessly released.

“It’s a fun game, isn’t it?”

With a slightly disappointed expression on her face that this was the end, she lifted her upper body and returned to her original position.

“Naturally, I’m wearing an apron now, but take it off in front of Su-ah.”

“Yes~”

Mom picked up her apron that had fallen on the table and tied it around her neck again.

“Hehe… I wish I could even recognize the mark on my neck.”

Her mother looked at me with a slightly sad face and muttered to herself.

“I need to take a shower”

I stretched and tried to get up.

“Junwoo. Is Sujeong awake yet?”

When her mood is over, her mother returns to her mother mode again and asks about her older sister’s mood.

“Yeah, I was really upset. I guess I’m skipping my part-time job, right?”

“But I’m at the age where I can take care of my own business, so it’ll be okay. Leave it alone.”

My dick instantly reacts to my mother’s words telling me to leave it alone.
My mother, who listened to my commands, immediately reacted to the sight of her speaking as the mother of her siblings.

“Should I wake up my sister?”

I take it a step further and ask her mom what to do.

“Just leave it~ Sujeong must have been very tired yesterday~”

As expected, in response to her mother telling her to leave it alone, her cock fully erects. The thought of repaying the favor by making her obey her mother’s commands made her fully erect.

“Yeah, I understand~”

Her cock was sore, but she couldn’t overcome her fatigue and headed back to the room.

Squeak-

When I came back into my room, my sister was awake, sitting on the bed with messy hair.

“Huhmm…”

“Aren’t you hungry?”

“Huh? I’m not hungry…”

Maybe it’s because she’s sleepy, but even when I tell her to speak informally, she continues to use polite language like yesterday.

“You’re going to buy swimsuits before going to the pool. That’s for the three of you, Mom and Su-a.”

“Ugh… Master, aren’t you going?”

My sister asked, running her hands through her hair that was falling in front of her. When she heard that I wasn’t going, her eyes widened, and she seemed to wake up.

“Ah, just buy something like that between mother and daughter. It’s also fun to see what you bought later.”

My sister thought for a moment and nodded her head slowly.

—

Shoot aaa-

We washed separately in our respective rooms without saying anything. Yesterday’s lewd content remained only on the action camera, and we returned to our daily lives as if nothing had happened.

I came out of the shower, imagining the strange situations I would show my neat sister again someday.

Tak-tak-

I walked around the room, leaving my cock erect.

My mother came to the room one more time, and she had left, so the blanket was gone and there were bread and milk on the desk.

“It’s so fast”

I don’t know if she was this good at taking care of the house even after she abandoned me and went to a new home, but she was much better at taking care of the house than when she first came to my house.

Click- Click-

While I was organizing the video from the action cam on my computer, it was already lunchtime. The sound of a crunching sound and something busy moving could be heard all the way to my room.

And the older sister’s voice, as if she were talking to her mother, can be heard clearly through the room.

“Is this too sexy? But it’s a bit weird to cover it all up, haha~”

She was the coolest sister, to the point where I doubted whether she was the older sister who competed with her mother below me.

Squeak-

“What are you talking about?”

I opened the door, went out, and joined my sister and mother.

“Junwoo. How about this? I heard that it’s easier to shop if you choose in advance, so I’m looking at it…”

Beneath her smiling older sister’s face, there was a mark on her neck similar to her mother’s. My sister’s neck had more vivid red bruises than her mother’s.

It was so clear that anyone could immediately tell that it was a trace of a strangled neck.

“Junwoo?”

This time, I couldn’t get used to my sister calling my name.

“Huh? Uh. That’s okay.”

I glanced at the picture of the bikini in front of me and roughly answered that it was okay.

Talk-

“Then what about this?”

My sister keeps asking me questions while flipping through the photos next to me.

“Wouldn’t it be better if we bought it and showed it to ourselves, Sujeong?”

My mom stopped my sister by just turning her head while she was cooking.

“Umm~ But if you know your tastes, wouldn’t you be able to choose something a little prettier? Actually, who is this swimsuit for?”

My sister looks at me with a sly look and speaks to her mother.

Now my sister didn’t feel awkward or embarrassed. There was a clear distinction between yesterday’s lewd slave No. 2 and the older sister.

“No. It would be more fun to pick each other fairly and hear who looks better.”

It seemed like she was scolding her older sister, but the meaning was planted that she wanted to be evaluated by her master as a senior slave. My mother strongly stopped my sister.

“Suya~!! Come out and eat~”

Her mom continued what she was doing. Suna sat down and pursed her lips.

Squeak-

Su-ah came out, and we sat down in front of the steaming table.

Su-ah and I sat side by side, my mother sat in front of her, and my older sister sat next to her mother.

Su-ah quietly left her room and sat down in her seat, as she always did. She didn’t exercise today. She was wearing skimpy beige pajamas.

“I guess you didn’t go to the gym today?”

“Yes, I’m tired”

Su-ah was cold, but answered.

“Now, should I try it too?”

Mom took off her apron and sat down in her seat. As expected, she was wearing a transparent bra with one strap undone.

If Su-ah saw her mother, she would be the first thing she would see.

Gulp-

Without realizing it, I was concentrating on this situation.

“Hmm~hmm~”

Her mother hums to her, and she looks happily at the meal she prepared.

However, Su-ah was quickly eating her meal, looking at her side dishes and rice in a dull manner. Fortunately, her older sister was by her side, so she couldn’t discover her mother’s flaws.

Her mother’s shoulder straps went down her arms and her breasts were positioned asymmetrically, so it was easy for her to see even when looking elsewhere, but it wasn’t easy for Su-ah.

“Soo-ah. About the mock exam…”

At that moment, it was her mother who opened her mouth first. She is a mother who faithfully carries out her duties even if I don’t tell her.

“Huh? Why?”

Only then did Su-ah raise her head and look at her mother. When I heard the word “Mock test,” My ears perked up, and I responded immediately.

‘As expected, Mom. She knows Su-ah very well’

“It’s too far to go to Gangwon-do, so I’m planning to get a room the night before and sleep… How about it?”

My mom blurts out the plan that my mom and I shared.

Su-ah thought for a moment, then realized what she was saying and nodded her head slowly.

“Room? It’s fine for me. It was a bit burdensome to have to go early and take the test.”

Su-ah spoke clearly even though she was muttering.

“Junwoo said he would have a hard time taking Sua’s exam, so he put her in a hotel~!”

And then Mom goes on to reveal that I proceeded.
