Chapter 194 – Incestuousness (If Side Story) Episode 19 – Sieun Unnie’s Slightly Strange Underwear Gift
Si-eun held her sister’s hand tightly and arrived at her underwear store.
A pretty female employee comes running in a month and responds with a bright smile.
“Welcome, customer. Are you looking for something?”
“Ah, yes… Hey, I’m trying to buy a new underwear because it’s getting a little smaller…”
“Then, let me help you measure your size first. Would you like to follow me this way?”
At first, she thought that she should just buy underwear, so she asked to go to an underwear store, but
When I came here, I must say it was a feeling of pressure, because there are mannequins wearing women’s underwear all over the place.
As much as I am a woman, there is no need to be ashamed… It was not easy to hold her face proudly.
“What are you doing, I have to follow you.”
It would be nice if her older sister would step in here,
She just looked at me with a smile that was half mischievous and half serious.
Are you trying to make fun of me, or are you trying to train me to talk to others like this?
“Ha…”
I let out a small sigh and started following the staff inside.
In the back of the store, there was a partition-like space that could be covered with a curtain.
An employee was waiting there holding a tape measure.
“Come in here, please take off your top and underwear.”
“Yes…”
“Can I come in too?”
“Yes? Oh, yes. You can come in with me.”
Pushed by her older sister, I, who entered the partition,
The situation ended up being surrounded by a female employee holding a tape measure in front of her, and her older sister who was smiling brightly next to her.
… Unni, she wouldn’t have had to come along.
After hesitating for a while while holding the collar, in the end, in front of the staff and Si-eun’s sister looking at each other at the same time… He slowly began to take off his shirt.
For some reason, Si-eun, who feels the heat of her sister’s eyes,
While swallowing saliva through her throat, trying to ignore the eyes of her older sister, the staff member watching over her,
Grasp the hem of the T-shirt and roll it up.
Below that, the beautifully split belly button and vivid 11-character abs are shown first,
The collar that kept going up caught on my big chest for a while, then came back to its original state,
The breasts wrapped in a beige bra sway slightly up and down, revealing themselves in the air.
Do you think she’s showing her underwear like this, with only a thin curtain in between the outside where people are walking around?
Strangely, my heart started beating fast… I feel like the gap between my legs is a little bit sad.
“Huh…”
Secretly rubbing her thighs, he took off the T-shirt pulled up to his chin and lifted it over his head.
Leaving it to her older sister for a while,
This time, with her hands behind her back, she unhooked her bra.
Then, the large raw breasts that were trapped in the brassiere were released freely,
She jumped up and appeared proudly in front of everyone’s eyes.
Perhaps because of the weird feeling from before, I was embarrassed about my slightly hardened nipples… ,
Holding out her breasts, resisting the desire to cover them with her hands even now,
Si-eun and her staff sister are just looking at my breasts with a very blank expression.
Are you not sizing up?
“Hey…? That size is a bit…”
“Ah, yes, yes! I’ll do it. Hey, wait a minute.”
Only then did she come to her senses, and the sister-in-law stretched her tape measure with both hands,
She passed her tape measure behind her on her back as she pressed her own breast lightly against my chest and gave me a rubbing hug.
She measures the length by wrapping the tape measure just below her breasts.
After that, briefly check the length of the girth with your eyes, and pull it up a little higher,
This time she held her breasts slowly with a tape measure.
“Yes…♡”
As her body was gently touched by her staff sister’s hand, the nipples that had become even harder,
It touches the cold, hard tape measure and gets rubbed.
In a situation where I was exposing my breasts in an unfamiliar environment, I, who was subtly getting hotter,
Feeling a slight pleasure from that alone… My body flinched softly.
I hope that the measurement will be completed soon before more strange sounds leak out, but I hope in my heart,
Maybe it’s because my breasts are so big, or because the staff sister kept rubbing her tape measure while whimpering… ,
The nipples keep getting harder under the tape measure.
By the time my head is getting softer and softer at the strange sensation that rises from the tip,
Piercing through my foggy mind, I heard Shi-eun’s sharp voice.
“That, haven’t you measured yet?”
“Yes? Ah, this is, that… Because the customer’s chest is so big…”
“If you’re having a hard time, just call another employee. I don’t intend to say anything about this.”
“No, I’m done measuring now…! Yes, the 75G cup came out…”
Shi-eun thinks that her older sister’s voice sounds a bit angry,
Is it simply my illusion?
“Seon-ah, wait here. I’ll go with the staff and find something for you to wear. Is your waist the same as before?”
“Ah, yes. I think my back is fine.”
So, after her sister Shi-eun left the cubicle with her sister-in-law,
I was left alone behind the curtain, staring blankly down at my chest.
Rather, a 75G cup… It’s really really big.
In the meantime, with only the impression that my heart is very big and heavy,
I’ve been wearing the bras in ‘Lee Seon-ah’s room without thinking…
Hearing the specific size of a G cup directly from the mouth of one of her staff members, the feeling that touched her head was different.
In the first place, I don’t usually think that I would see a G-cup size in real life.
But it was right under my sight.
“Wait a minute… If I’m a G cup, Yeeun’s mother’s breasts, which are slightly bigger than mine, are… H cups?”
Shi-eun unnie is a bit shorter than me, so she’ll probably be an E cup.
Sua, the smallest in our family, is about a C cup?
At this point, a very unrealistic feeling springs up.
Blinking my eyes gently, I looked down at the once again huge breasts,
I grabbed it lightly with both hands.
Very heavy, elastic, large breasts that cannot be held in one hand.
While idly enjoying the feeling of touching someone else’s chest, not my own,
I put my hand down in a hurry at the sound of shoes coming from outside.
Immediately after that, the curtains opened with a squeak from the side.
“…What were you doing?”
“Oh, no, I didn’t do anything…”
Returning with her wrapped black underwear in one hand, Shi-eun’s older sister looks at me and makes a strange expression.
… That’s right, while I went to get my underwear for a while, it would look strange if I was standing alone with a blushing face.
I was flustered for a while, then Shi Eun snatched the underwear from her sister’s hand and turned her words around.
“Rather than that, what did you bring?”
“Try to open it yourself.”
“Uh… Shouldn’t I just open this?”
“It’s okay. I already bought it.”
… Didn’t even try it on, but already bought it?
Umm… After all, this is the heart of the person who gives money.
Thinking so, she tore open the transparent packaging, took out her underwear, and unfolded it.
“…What’s this?”
“No big deal. Just plain underwear.”
“Plain… Underwear?”
“Yes. Isn’t the design pretty?”
Si-eun, who is making her proud expression, stares blankly at her older sister,
She turned her gaze back to the underwear in her hand.
In the center of the black brassiere that should have covered her breasts, there is a long, diamond-shaped gap.
The pants with a small area also had a long gap in the same shape at the place of the pussy.
Besides, the other fabric parts are also subtly see-through…
It was a design that no one could say that it was ‘ordinary underwear’.
“Why, what’s wrong?”
“Ah… No. The underwear is very pretty.”
Except for one person, me, who has ‘amnesia’ and doesn’t know anything.
I couldn’t even complain, just staring at it,
“Hurry up and try it on. I have to go see a movie later.”
“Yeah, I will.”
At her sister’s urging, Shi-eun even took off her panties, which she was wearing for the time being.
… Could it be that my sister is playing a prank on me?
Thinking like that, it’s not even a try-on, it’s underwear that I’ve already paid for.
Glancing at her older sister, she looked at her serious eyes, devoid of any playfulness of hers,
She was staring at my naked body.
I can’t help it…
I can’t stand like this all the time, and for now, let’s wear this as my sister wants.
I let out a small sigh and tucked each leg into the panties smaller than the palm of my hand.
And when I snuck-up her laces…
The thin string at the waist draws a steep V shape between the legs, tightly wrapped around the lower body,
Through the gap in the middle of the panties that barely covered the mound of her pussy, as expected, the cracks in her pussy were exposed.
At least, on the hip side, there was no fabric and only one string barely penetrated.
It was connected to the string around her waist, drawing an obscene Y shape.
I looked at Si-eun’s older sister again with a look that made me wonder if this was right.
Pushed by her silent urging, this time she took her bra in her hand.
Once I put my arms in her shoulder straps, and put my breasts on the cups of my bra,
While holding the string behind her with a hook… So that the bra and breasts fit properly,
In front of her older sister’s burdensome gaze, Shieun herself pushed up her breasts and adjusted her position by touching them.
“Uh, how are you?”
“…So pretty.”
From above, pink nipples and areolas,
From below, the cracks in her slightly wet pussy,
Exposed nakedly through a long diamond-shaped slit,
She succeeded in wearing a black lace lingerie set convincingly.
Seeing me twisting my body shyly in embarrassment, Shi-eun unnie looked blankly at me,
Little by little, he came forward and gently hugged my waist.
“Because my sister gave me such a pretty present… Can I get a kiss?”
Si-eun, who whispered in her voice that felt her great heat, looked at her older sister,
I nodded quietly.
“I’m sorry—♡”
Right after that, with hands violently grabbing my breasts,
Sieun began rubbing her sister’s soft lips.
