Chapter 240
Slap! Slap! Slap! Slap! Slap!
The light, rhythmic sound of Si-woo masturbating echoed softly within the changing room.
According to Se-hee Noona, the frosted glass door allowed those inside the shower to clearly see the movements of anyone outside, but Si-woo didn't care about that anymore.
In fact, he was now masturbating while imagining Mom and Se-young watching him through that very glass.
For a while, Si-woo continued his careful stroking, admiring the blurred silhouettes of the two naked women visible through the door.
Watching the hazy outlines of Mom and Se-young’s bodies and the soft glow of their skin while he pleasured himself made him feel dizzy with excitement.
The two female forms inside the shower moved naturally, as if they hadn't yet realized Si-woo was in the changing room.
He felt a mix of relief, a hint of disappointment, and a strange sense of yearning.
As if to soothe those complex emotions, Si-woo took out his smartphone to record himself masturbating with Mom’s bra.
Click! Click! Click!
With Se-young’s underwear and Mom’s panties laid out on the side table—and the red dog collar as a backdrop—Si-woo captured images of himself stroking his penis.
After taking the photos, he draped Mom’s bra over the base of his throbbing shaft.
Then, he reached out and picked up Se-young’s bra from the table.
Holding both Mom’s and Se-young’s bras together, he wrapped them around his cock and began to pump his hand up and down.
Slap! Slap! Slap! Thwack! Thwack!
There was the smooth, straight pink fabric of Se-young’s bra, which offered little resistance, and the textured, white lace of Mom’s lingerie bra.
The two different textures rubbed and chafed against the thick skin of Si-woo’s cock simultaneously.
The pre-cum leaking from the tip of his penis soaked into both Mom’s and Se-young’s bras at once.
Si-woo thought about how Se-young might find it incredibly strange when she finished her shower and saw her bra drenched in pre-cum.
But he realized he didn't care what Se-young thought anymore.
Every time the friction occurred between the soaked fabric and his massive genitals, a surge of transgressive pleasure and excitement filled his chest.
Enduring the looming urge to ejaculate, he took another photo of his cock being rubbed by his hand.
Click! Click! Click!
This time, he changed the angle, using the frosted glass door with Mom’s and Se-young’s silhouettes as the background.
Si-woo suppressed the sudden impulse to burst into the shower room where they stood naked.
He barely managed to stop his hand just before reaching the climax.
He intended to release all of this pent-up excitement and the frustration of holding back onto Mom tonight.
He placed Mom’s and Se-young’s bras, now heavily stained with his pre-cum, back onto the side table.
Immediately, he sent the photos he had just taken to Mom’s smartphone.
In the tense silence, the notification sound from Mom’s phone seemed to ring out much louder than usual.
Once Mom finished her shower and came out to the changing room, she would check the video, the text, and the photos Si-woo had sent as part of his "mission."
Having finished all his preparations exactly as he intended, Si-woo left the changing room.
* * *
Si-woo walked into the living room and approached the sofa where Se-hee Noona was sitting.
Se-hee Noona was watching TV, dressed exactly as Si-woo had left her earlier.
She was wearing the black mesh T-shirt over her snakeskin pattern underwear.
Si-woo sat down right next to her.
He wrapped his arm around her and pulled her into his embrace as if nothing were wrong, flipping through the TV channels with the remote.
Then, he naturally slid his hand under Se-hee Noona’s mesh T-shirt.
Pushed up by his arm, the mesh fabric was pulled high up her side.
As he pushed her bra up slightly, one of Se-hee Noona’s large, luscious breasts was revealed beneath the mesh.
With the hand already draped around her, Si-woo leisurely began to knead the exposed breast.
As he massaged her large breast, he used his index finger to flick her erect pink nipple up and down.
"Hngh..."
A faint moan escaped Se-hee Noona, whose mouth was still filled with his semen.
Si-woo spent a moment simply gripping and squeezing her breast, toyed with it as he pleased.
"That... it's the drawer key, right? For Se-jin Noona’s room..."
After fondling her breast for a long time, Si-woo asked her the question in a casual, passing tone.
It was about the small brass key he had received the morning after the threesome with Aunt Seon-ju.
After seeing the photo of a pregnant Se-jin Noona on Se-hee Noona’s smartphone, he had a vague suspicion that the key originated from Se-jin Noona.
And not long after arriving home, he had realized where that key was likely meant to be used.
Se-hee Noona, who had been staring fixedly at the TV screen, flinched and looked back at Si-woo as if a shameful memory she had tried to bury had been brought back to the surface.
She carefully watched his reaction before nodding her head up and down.
It seemed the key Si-woo had been given was indeed sent by Se-jin Noona.
"Did you check it?"
Si-woo asked, pinching and twiddling her nipple between his thumb and forefinger.
Se-hee Noona’s body trembled as if reacting to the stimulation of her nipple.
Soon, as if shaking off her shame, she shook her head from side to side in denial.
"Do you know what's inside?"
Si-woo continued to verify his questions about the key one by one, scraping his fingernail against her nipple as if mocking her.
Se-hee Noona shook her head again.
"So Se-jin Noona sent it for me to check? And you just handed it over to me like that?"
Si-woo scolded her, recalling the arrogant attitude Se-hee Noona had shown when she gave him the key.
That morning, she had punched Si-woo in the stomach, shoved the key into his pocket without a word, and disappeared into the academy.
"Hngh... Hnnngh... Mmm..."
Se-hee Noona also seemed to remember that morning; she let out a series of moans that sounded like excuses, looking flustered in front of her younger brother to whom she had declared her submission.
"Shut up! Suck this until Mom comes out! You fucking bitch!"
Still sitting on the sofa, Si-woo thrust his bulging penis forward and commanded her.
"Hngh..."
The sound of excited, trembling breaths escaped Se-hee Noona’s nose.
Following Si-woo’s command, she leaned over from her seated position toward her brother and took his large member into her mouth.
Careful not to let the semen already in her mouth spill out, she took Si-woo’s cock in deep.
He felt the hot, slick sensation of the inside of her mouth.
A thrill of pleasure wrapped around him as Se-hee Noona’s lips and tongue swirled around his glans.
Her tongue swept over his glans as if reapplying the semen onto it.
Si-woo placed his hand on Se-hee Noona’s head, controlling the up-and-down motion of her head.
While receiving the oral sex, Si-woo thought about the key the pregnant Se-jin Noona had sent through Se-hee.
The drawer locked by that key likely contained the family secrets he wanted to know.
Everything from Mom’s past to the special contract documents he had been searching for...
Documents that would confirm Mom and her daughters were destined to be Si-woo’s property from the very beginning.
As the rightful heir, Si-woo wanted to check the inheritance clauses written within those documents.
He imagined Mom signing a Slave Contract according to the proper format.
He pictured Se-hee Noona, Se-young, and even Se-jin Noona signing the contracts while being penetrated.
As his thoughts reached that point, Si-woo’s heart began to pound wildly.
"Tonight, after I put Se-young to sleep in the master bedroom, I’m moving you to your room, Se-hee Noona~"
Si-woo spoke to her as if delivering an ultimatum while she continued to suck him.
As he spoke, the way he addressed her shifted from "Se-hee" back to "Se-hee Noona."
Se-hee Noona used her teeth to nip at the sensitive skin of his glans.
"Ah!"
A sharp, stinging pleasure accompanied by a hint of pain was etched into the grooves of his glans.
