Chapter 299 (Seon-ju, Se-young)

The swell of Se-young’s breasts felt soft and supple beneath his fingertips.
"Don't you think this dress is a bit too thin? You're not even wearing a bra right now, are you?"
Si-woo spoke as he lifted the fabric of the dress covering her chest, as if checking the skin beneath.
Under the thin fabric lifted by Si-woo’s hand, the soft flesh of her breasts below the collarbone and her pale pink nipples stood out prominently.
Continuing downward, her smooth stomach, the orange striped panties covering her groin, and her plump, snowy-white thighs were revealed, as if tinted by the shadows of the light blue dress.
Right in the middle of the street on the way to Aunt Seon-ju’s house, Si-woo was pulling Se-young’s clothes forward and peering inside.
Currently, Si-woo and Se-young were treating each other under the guise of being ordinary, close siblings.
Even between the closest of siblings, this was something that would generally never be permitted.
Even if they had seen each other’s stark naked bodies at home...
Or even if there had been sexual contact while one was sleeping...
Furthermore, this was a sudden, wretched act of lewdness being carried out by Si-woo on a quiet residential street where they could encounter any number of strangers at any moment.
Si-woo expected Se-young to act at least a little shy, to shrink back, or to use her arms to press down and hide the clothes he was lifting over her chest.
However, despite Si-woo’s sudden actions, Se-young kept her back straight and walked naturally as if nothing were happening.
"Yeah~ I'm only wearing panties underneath~ I thought it was still a bit early for a bra! What do you think, Oppa? Does it look really weird?"
In response to Si-woo’s question, Se-young answered with a nonchalant attitude, as if it were nothing at all.
She questioned her brother—who was lifting her clothes at will and peering at her bare skin—as if asking for his impressions and opinion of her body.
"Ah... no... it’s not weird! It’s pretty... I think you can wait until your breasts get a bit bigger before you start wearing a bra."
Si-woo answered while looking down at Se-young’s pudding-like bare breasts with a strange sensation.
Does this mean that even while she's conscious, it's now permitted to look at Se-young’s skin whenever I want?
The two siblings were sharing a conversation as if it were a daily routine, using the developing breasts of the younger sister as the subject.
This kind of suggestive conversation, held while staring directly at Se-young’s breasts, made Si-woo’s heart beat so fast it felt like it might explode.
"Is that so~? I hope mine get as big as Se-hee Unnie’s or Mom’s soon, too~ Hehe~"
Se-young spoke as if she were accepting Si-woo’s lewd advances without a second thought, as if it were a familiar topic they discussed all the time.
"I think Se-young’s nipple color is much prettier than Seon-mi’s or Se-hee’s."
Si-woo spoke while observing Se-young’s pink nipples, comparing them to their mother and Se-hee Noona.
Furthermore, Si-woo was casually calling his mother by her name, Seon-mi, as if she were his subordinate, just as he did with Se-hee Noona.
Last night, Si-woo had explained to Se-young that he only called their mother by her name at night because he was humoring her spoiled behavior.
However, since he had decided there was no longer any need to worry about the titles of the family members who had become slaves—even in front of Se-young—Si-woo had subtly tested the waters by calling his mother by her name.
"Hehe~ Really~?"
Se-young asked back, seemingly delighted by Si-woo’s compliment.
Se-young showed no sign of wonder or awkwardness at the fact that Si-woo was calling their mother by her name even though it wasn't nighttime.
While constantly exchanging words of risky intensity and sexual actions that could collapse the ambiguous relationship between them at any moment...
Si-woo’s excitement reached a fever pitch at the contradictory thoughts and sensations of trying to maintain the balance of daily life.
Si-woo let go of the fabric of Se-young’s dress that he had been holding up with his index finger.
"Yeah~ Really! And your size will probably increase soon anyway! Look at Se-hee; hers started growing once she moved up to the Intermediate Academy! Remember?"
Si-woo spoke as he lightly supported the underside of Se-young’s breast with his palm.
Se-young’s soft, squishy breast settled into Si-woo’s palm.
"Is that so?"
Se-young puffed out her chest slightly, leaning forward while simultaneously bowing her head to stare down at her own breast that Si-woo was holding.
Si-woo took courage from Se-young’s calm reaction.
Applying pressure with his hand, Si-woo began to knead and squeeze Se-young’s breast.
Even at Si-woo’s provocative actions, which had long since crossed the line, Se-young made no move to shake off Si-woo’s hand or avoid him.
She simply stood there with a beaming smile, as if she were completely unaware of the molestation or sexual stimulation her brother was inflicting on her...
Si-woo’s penis was already swollen to the point of bursting.
A powerful impulse surged within him to strip Se-young of all her clothes right then and there and rape her in the middle of the residential street.
Would Se-young accept even that kind of behavior from Si-woo with the face of an innocent younger sister?
* * *
"Oppa! By the way, what happened to the perfume I gave you?"
Se-young watched her brother, who had been kneading her breasts, and asked in a bold tone.
In that moment when his reason was becoming paralyzed, Si-woo faltered for a second, seemingly flustered by Se-young’s sudden question.
"Per... perfume? Ah... that... well... I took it out in my pocket the day before yesterday... and, uh... I... I accidentally tripped and..."
Si-woo was trying to make an excuse to Se-young about breaking the perfume.
"You broke it? Ugh~ You should have been more careful!"
Se-young interrupted her brother, speaking in a scolding tone.
"Sorry..."
Si-woo immediately apologized to Se-young.
The hand that had been gripping Se-young’s soft breast had been withdrawn behind his back before he knew it.
"Did you get hurt when the glass bottle broke?"
Se-young spoke while looking at Si-woo with concern.
"Yeah! I don't think I got hurt!"
Despite having various wounds on his face from the traces of a fight, Si-woo spoke boastfully as if he hadn't been injured at all.
Se-young looked at Si-woo’s face for a moment with a pitying expression.
"Then... you might not be able to recognize me later..."
Se-young stared at Si-woo’s face with an unreadable expression before whispering quietly to herself.
"What?"
Si-woo reacted instinctively, questioning her cryptic words.
"Do you remember the scent of the perfume?"
Se-young continued to ask Si-woo questions that lacked context.
"Huh? Uh... the scent... I remember it..."
Caught off guard, Si-woo answered Se-young’s question with an uncertain tone.
"Then that’s fine~ Hehe~"
Se-young’s tone shifted from scolding back to her usual bright and kind manner.
"I'm looking forward to the aquarium today~!"
Se-young said that and then unlinked her arm from Si-woo’s.
As if urging Si-woo to hurry, she stepped three or four paces ahead and walked with her back to him.
The everyday words he had spoken along with the molestation while moving Se-young to Se-hee Noona’s room last night flashed through Si-woo’s mind.
While holding Se-young’s buttocks as they faced each other, Si-woo had been rubbing his penis against the crevice of her nearly naked body.
In that position, Si-woo had been rambling on to the sleeping Se-young about the broken perfume and the aquarium.
At the thought of "no way," Si-woo’s head felt a bit dazed.
Se-young, wearing her light blue dress, walked vibrantly ahead of him.
Watching Se-young’s seductive backside, Si-woo’s penis throbbed with a full, tingling erection.

Before they knew it, they had arrived in front of Aunt Seon-ju’s house.
Aunt Seon-ju’s house was a detached home with a large yard.
The planted trees, the structures, and the shape of the building gave off a strange atmosphere, as if it had come out of a European fairy tale.
Arriving a few steps ahead, Se-young pressed the doorbell for a long time as if she were used to it.
"Oh~! Se-young and Si-woo are here already? Just a second~! Su-a is doing something right now~"
Not long after, Aunt Seon-ju greeted her niece and nephew with a bright voice through the intercom.
Clack!
And soon, the iron gate of the entrance opened.
"I guess Su-a isn't ready yet~ Let's go in and wait~ Si-woo Oppa!"
Se-young looked back at Si-woo with a slight smile and entered through the open door.
Si-woo followed Se-young into Aunt Seon-ju’s house.
Aunt Seon-ju’s yard was filled with the full energy of spring.
Green grass and flowering trees were planted densely throughout the spacious yard.
Se-young and Si-woo walked lightly and refreshingly along the stone path of polygonal blocks that led from the gate to the front door.
In one corner of the yard, a large dog tied to a chain was watching Si-woo with its neck held stiffly as if on guard.
It was a Great Dane that Aunt Seon-ju had been raising for quite a long time.
It had a massive build, with its head reaching about the height of Se-young’s chest.
If measured from its hind legs to its head, it was likely large enough to easily surpass the height of an adult woman.
Was its name Ben?
It was the owner of the large iron cage Se-young had sent a photo of this morning.
