Chapter 283 (Mom, Se-young)

Si-woo’s heart was pounding wildly as he stepped into the master bedroom.
His massive cock throbbed in sync with the heavy rhythm of his heart.
The towel he had wrapped around his waist had already come undone; it hung precariously off his hips, draped over his penis like a hood without him even needing to touch it.
There was no way Se-young could have missed it—the sight of Si-woo’s imposing, majestic erection.
While his penis had brushed against Se-young’s body many times before under the guise of accidents, this was the first time he had intentionally shown her such a blatant erection since that morning she had come into his room to wake him up.
Just the thought that Se-young must have seen his fully erect cock beneath the towel moments ago made his member twitch with renewed vigor, feeling as though it might burst.
And this was despite having just ejaculated twice—once into Se-young’s panties and once into his mother’s body...
Si-woo looked down at his enormous penis and took deep breaths, trying to calm his racing heart.
With every breath, he inhaled the scent of lewd bodily fluids.
The pungent, carnal aroma lingering in every corner of the master bedroom brought back the vivid, frenzied memories of the previous night.
Because of that, his erection showed no signs of subsiding, no matter how much he tried to steady his breathing.
* * *
Leaving his erection as it was, Si-woo opened the drawer of the bedside table.
Hidden in the far corner of the drawer was a box of ten large-sized condoms, already opened.
Si-woo reached in and rummaged through the corner where his mother must have carefully hidden them, pulling the box out.
He took a single foil-wrapped condom from the box and clutched it in the same hand holding his smartphone.
Next, he walked straight to his mother’s wardrobe and began searching for clothes for her to change into.
From the wardrobe, he pulled out an oversized purple t-shirt that his mother often enjoyed wearing.
It was a large shirt that reached down to mid-thigh.
It was just barely long and wide enough to hide the humiliating phrases Si-woo had written all over his mother’s body.
It seemed Si-woo had no intention of letting her wear any bottoms.
He imagined his mother going about her day in front of the family wearing nothing but that single t-shirt, her lower half completely exposed underneath.
Si-woo brushed the towel off his penis and let it drop to the floor.
The dark red mass of flesh was now fully exposed.
He wrapped his mother’s purple t-shirt around his penis and rubbed it as if masturbating.
The soft texture of the fabric felt like a provocative caress against the skin of his cock.
Si-woo’s pre-cum stained the shirt where it touched his glans, leaving damp spots on the fabric.
Holding his mother’s purple t-shirt wrapped around his penis, Si-woo paused for a moment, lost in thought.
A wicked prank suddenly crossed his mind.
He set his smartphone and the purple t-shirt down on his mother’s bed for a moment.
Then, he tore open the condom wrapper.
He rolled the condom onto his fully engorged penis.
Now fully prepared for safe insertion right there in the master bedroom, Si-woo picked his phone and the oversized t-shirt back up.
His plan was to head straight to the changing room with his mother’s clothes.
Since he would naturally have to pass through the living room, which was open to the kitchen, Se-young would inevitably see him.
The only thing he had to hide his condom-clad penis was the purple t-shirt he was bringing to his mother.
And once he gave her the shirt, even that cover would be gone.
Si-woo draped the purple t-shirt loosely around his waist to cover his erection and stepped out of the master bedroom.
His breath came in short, ragged gasps as he thought about flaunting his erection to Se-young from beneath the shirt.
* * *
Stepping out of the master bedroom, Si-woo’s heart hammered against his ribs as he stole a glance toward Se-young.
She seemed to be finishing up the breakfast preparations in the kitchen.
Si-woo walked across the living room, pretending everything was normal while using the t-shirt to hide his condom-clad penis.
He headed toward the changing room in silence, without turning his head.
The sound of side dishes being arranged echoed from the kitchen.
He wasn't entirely sure if Se-young was watching him as he walked toward the changing room.
Pretending it was an accident, Si-woo let the t-shirt covering his penis slip down slightly.
The tip of his condom-covered penis peeked out for a fleeting second, exposed just enough to be seen before he covered it again.
The sounds from the kitchen stopped abruptly, as if falling into a sudden void of silence in sync with his movement, before starting up again.
A shiver ran down Si-woo’s spine.
Se-young was watching his erect form from behind.
For the first time, Si-woo had let her see the tip of his penis with a condom on it.
A dizzying sense of achievement washed over him, mingled with embarrassment.
It felt as if every hair on his body was standing on end.
His pace quickened, and he practically hurried into the changing room as if fleeing from Se-young’s gaze.
* * *
Si-woo stepped into the changing room, hiding himself from Se-young’s sight.
His breathing was heavy with the excitement filling his chest, and a faint tremor ran through his entire body.
His penis, standing tall as if it might burst, was a testament to his state of arousal.
Through the glass door of the shower room, he could see the flesh-colored silhouette of his mother kneeling and carefully washing her hair with the showerhead.
After calming himself slightly at the sight of her, Si-woo placed the purple t-shirt on the small side table.
Then, he gathered his mother’s clothes scattered on the floor and threw them all into the washing machine.
Even the bra Mom was wearing...
"Mom! I brought you some fresh clothes. They're on the table. Just wear this today! Got it?"
Si-woo issued the command toward his mother in the shower.
He saw her silhouette flinch and stop moving at the sound of his voice.
"Y-yes... okay... Th-thank you..."
His mother answered her son in a trembling voice.
"Then I'm going upstairs to wake up Se-hee Noona now."
Si-woo spoke as if reporting to his mother about the sex he was about to have with Se-hee.
"......Okay."
After a brief hesitation, his mother gave a short reply.
Then, she resumed washing her hair.
As per Si-woo’s command, his mother would spend the entire day wearing nothing but that oversized purple t-shirt.
Seeing his mother submit so obediently to his will helped Si-woo’s heart settle a little.
Si-woo was now completely naked.
The only thing covering any part of his body was the single condom stretched tight over his penis.
His fully erect cock was encased in nothing but that thin, transparent layer of latex.
Si-woo intended to head to the second floor without even trying to hide his erection.
* * *
Si-woo pulled the curtain of the changing room entrance aside and stepped out into the living room.
He stood there, completely naked, with his penis standing bolt upright.
He faced the stairs to the second floor, pointedly not looking toward the kitchen.
Now that he was actually out in the living room, intending to show his naked body to his younger sister so openly, an uncontrollable surge of shame and embarrassment rose within him.
Was Se-young watching her brother standing in the living room in such an aroused state?
Did she know that the rubber film covering his penis was a device used to prevent pregnancy?
Seeing his erect penis and the condom on it, would Se-young imagine the sexual acts her brother was about to perform with their mother or Se-hee Noona?
Every time those thoughts crossed his mind, a wave of pleasure throbbed through him, making his chest vibrate.
Si-woo walked slowly toward the stairs leading to the second floor.
He felt as if Se-young’s subtle gaze was piercing his back like an electric current as he walked away from the changing room.
Pretending not to notice the eyes fixed on him from behind, he walked slowly, then suddenly, as if possessed, he gripped his penis with one hand.
He stopped for a moment and lightly shook his massive, condom-covered cock up and down.
Slap! Slap! Slap! Slap!
The sound of flesh hitting flesh echoed softly in the space between the changing room and the stairs.
After a very brief moment of stroking himself, he let go and resumed walking toward the stairs.
Unlike before, there was no sudden break in the sounds coming from the kitchen.
He couldn't be certain if Se-young was actually watching his naked body and his brief masturbation from the kitchen.
However, the new thrill and stimulation Si-woo had discovered made his face flush hot and stinging.
His hands trembled, and a cold sweat seemed to break out on his back.
Finally, Si-woo reached the stairs to the second floor.
He began to climb them, one step at a time.
With every step he took, his stiffly erect member bounced in the air like a spring.
By the time he reached the second floor, Si-woo’s heart was pounding so hard it felt like it might explode.
