Chapter 41 (Se-hee)
"Noona, what time are we going to the department store today?"
Si-woo was asking Se-hee Noona while masturbating with her panties as she took a shower.
"Hmm~ I’m planning to head out around eleven, so get ready~"
Se-hee Noona’s voice drifted from the other side of the frosted glass sliding door of the bathroom.
Normally, when Mom was home, it was strictly taboo for Si-woo to even enter the changing room while Se-hee Noona or Se-young were showering.
The strict family rules that had been implicitly observed for so long were now crumbling away into insignificance.
The natural flow of conversation with Se-hee Noona served as a massive stimulant for Si-woo.
Si-woo took the blue striped panties Se-hee Noona had discarded and smeared her pussy fluid evenly over his hard, throbbing penis.
The slippery feel of Se-hee Noona’s pussy fluid combined with the soft texture of the fabric.
Si-woo wrapped his massive penis in Se-hee Noona’s damp, soaked panties, rubbing them up and down to create friction.
A pleasure as sweet and mysterious as honey seemed to spread from his cock throughout his entire body.
"Are we eating lunch out?"
Si-woo intentionally kept the conversation going while masturbating, just to hear Se-hee Noona’s voice more.
"Yeah, Noona will buy~"
Before entering the shower, Se-hee Noona couldn't have missed the traces Si-woo had left behind—the heavy loads he’d spilled over her clothes in the laundry basket and the thick male scent that filled the changing room.
It should have been awkward to carry on a conversation through a glass door with a younger brother who had just finished masturbating, but Se-hee Noona continued the chat as if nothing were out of the ordinary.
Se-hee Noona also knew that her naked, flesh-toned body was visible to Si-woo as a silhouette through the sliding glass door.
The thrill of their unspoken communion in this deviant behavior seemed to be gradually dulling their rational thoughts about reality.
* * *
"Si-woo, you haven't been to the aquarium in the department store yet, have you?"
"No, never. Have you been there, Noona?"
"I’ve gone a few times after my academy classes~"
"By yourself?"
"No~ with friends. The atmosphere there is really nice, you know?"
"Really?"
"Yeah. I think we can have lunch, watch a movie, stop by the aquarium, and then head home. We have plenty of time, so we can look around and do some shopping too~"
Se-hee Noona briefly explained the schedule for the day.
* * *
Continuing to masturbate as they talked, Si-woo watched Se-hee Noona’s seductive movements through the frosted glass—bending at the waist or crouching down—and imagined her swimming naked inside an aquarium tank.
"Se-hee Noona~ how’s that thing you were going to do with Shin-bi Noona going?"
Si-woo brought up the conversation he remembered from when Shin-bi Noona had visited, where the two of them had talked as if excluding him.
"What? Which thing?"
"The talk you guys had when Shin-bi Noona came over and we ate ramen. Was it about a diet?"
Si-woo already knew what they had been talking about because he’d heard it from Shin-bi Noona, but he feigned ignorance to test Se-hee Noona.
"Huh? Oh... yeah, that~"
Se-hee Noona answered vaguely, as if trying to gloss over it.
It seemed she understood what he was referring to.
Unlike before, when she had treated him coldly, Se-hee Noona’s attitude toward Si-woo had become much gentler.
* * *
Si-woo momentarily imagined a scene of having sex with Se-hee Noona to "help" her with her diet.
He imagined pulling Se-hee Noona’s wet body straight out of the aquarium water, stretching her out face-down, and then mounting her from behind, thrusting his cock into her pussy as if raping her.
Then, he would start pounding into her mercilessly, pinning her down without rest.
A sex of coercive and violent humiliation.
Just imagining the moans Se-hee Noona would let out while pressed under his body sent a jolt of pleasure vibrating through him, and a sudden urge to ejaculate rushed over him.
"Looking at you now, Noona, I don't think you need to lose weight~ You look great as you are."
Si-woo spoke with his eyes fixed on the silhouette of Se-hee Noona’s body through the frosted glass.
As he spoke, he increased the speed of his hand on his cock.
The sound of flesh hitting flesh at his groin began to echo faintly.
Slap!
Slap...!
Slap...!
After a brief silence, Se-hee Noona spoke.
"If I let my guard down, I’ll gain it all back in an instant~ Mom makes sure we eat so regularly at our house."
"Is that so?"
"I’m telling you, because of Mom, I can't even dream of a diet where I skip meals."
Si-woo smiled slightly at Se-hee Noona’s cute excuse.
He remembered the dessert cafe in front of Se-hee Noona’s academy they had visited before.
—The lewd Se-hee Noona, who even succumbs to temptation while making such earnest excuses.—
"So, did you decide to do that diet with Shin-bi Noona?"
"I haven't decided yet~"
"Does that thing even work?"
"I don't know...? From what I hear from friends who are doing it, it doesn't seem too bad..."
"I guess a lot of your friends are doing it?"
"Y-yeah... but why are you so interested in my diet anyway?"
Se-hee Noona spoke to Si-woo with a hint of discomfort at his interest in the diet.
"No, I just wanted to help you if it’s something I can do~"
"Ha—do you even know what it is?"
Se-hee Noona let out a hollow laugh and asked him.
"Whatever it is, it’s something I’d be doing with you, Noona."
As he said that, Si-woo increased the speed of his hand gripping and shaking his penis even more.
Slap!
Slap!
Slap!
The sound of flesh hitting flesh, just barely audible to Se-hee Noona, echoed through the changing room with increasing momentum.
Si-woo was masturbating secretly, feeling the thrill of potentially being caught, but at the same time, he secretly hoped Se-hee Noona would notice.
He felt a vague expectation and certainty that even if she caught him, she wouldn't get angry today.
Noona fell silent again for a moment.
"I haven't decided whether to do it or not yet~ I need to talk to Shin-bi more... and besides, it’s not something I can do with you anyway, Si-woo."
Se-hee Noona spoke as if drawing a line.
"Why?"
"There’s just a reason!!"
Through this conversation, Si-woo was now certain that the diet Se-hee Noona and Shin-bi Noona were planning was indeed the one he knew about.
Even though he had written the word "SEX" on Shin-bi Noona’s palm and received confirmation that it was the correct answer—along with a reward for getting it right—a part of his mind had remained skeptical, wondering if it could really be true.
Perhaps a part of him had hoped it wasn't true.
Shin-bi Noona was exactly the kind of person who would play that kind of prank on him.
"I don't think it would matter to me?"
Si-woo spoke again, testing her.
"Ha—Si-woo, I’m asking if you even know what it is?"
Se-hee Noona let out another hollow laugh, sounding incredulous.
"Either way, it’s something I’d be doing with you, Se-hee Noona. I think I’d be fine with anything."
Si-woo was speaking to her with sex clearly on his mind.
* * *
Seeing Se-hee Noona’s panties soaked with pussy fluid, Si-woo knew she was reacting to him sexually.
He had been recognized as a male by Se-hee Noona.
In such a situation, it was unacceptable for Se-hee Noona to have sex with any man other than himself.
As if showing off to her, Si-woo gripped his cock with force and stroked it violently.
Squelch, slap! Slap!! Slap!!! Slap!!
The changing room was filled once again with the sound of the shower from the bathroom and the sound of Si-woo’s masturbation.
Se-hee Noona must have been sensing something, as she was now silent and motionless.
Standing naked under the spray of the shower, listening to her younger brother masturbate.
A long silence followed.
Soon, the urge to ejaculate surged through Si-woo.
Among Se-hee Noona’s clothes on the bedside table, the green shell-shaped bra he had seen earlier caught his eye.
Si-woo quickly grabbed the green bra and pressed it against the head of his penis.
Then, looking toward Se-hee Noona, he performed the final, climactic piston thrusts to reach ejaculation.
Slap slap slap slap slap~!!
"Uuugh... mmm, haaa~"
Si-woo let out a moan as he began to ejaculate.
He vented his semen in a cool, powerful spray, filling the inside of the shell-shaped green bra Se-hee Noona had been wearing.
A refreshing second ejaculation, free of guilt, shame, or emptiness.
Seeing as Se-hee Noona had left the bra on the table instead of in the laundry basket, she must have intended to put it back on after her shower.
How would she react when she saw that Si-woo had ejaculated into the bra she had briefly set aside to wear again?
Si-woo carefully placed Se-hee Noona’s bra into the laundry basket.
Then, as if nothing had happened, he silently slipped out into the living room.
Si-woo was about to start another day just like that.
