As dinner was wrapping up, Jinwoo caught his sister's eye and didn't know where to look, so he just kept his head down and shoveled food into his mouth. That's when his mom chimed in.
"Mom's gonna shower first, so Jinwoo, you handle the dishes and clean up, got it?"
Embarrassed and ashamed from being caught by his sister, Jinwoo, still avoiding eye contact, just pushed his rice and sides around his plate as he mumbled a response.
"Got it."
Mom then instructed Sohee and Minji as well.
"You girls just help move the dishes."
"Okay, got it."
Their responses echoed.
"Minji, you sleeping in Mom's room again tonight?"
Getting up from her seat, Mom asked Minji in a tone that felt like she was doing a headcount on a group trip.
"Yeah, with Mom..."
Minji trailed off shyly, seeming embarrassed to answer in front of her brother and sister.
"Alright."
Mom calmly replied and headed downstairs to shower.
"Bro, should I help you with the dishes?"
Minji, who had quickly stood up to move the dishes, asked eagerly.
"No, it's almost done. I can handle it myself."
Jinwoo had to decline Minji's sweet offer since he was still dealing with an unresolved erection.
After moving the dishes from the table to the sink, Sohee and Minji headed back to their rooms.
Jinwoo had felt a burning shame when he was caught ogling his mom's ass just moments earlier by his sister. However, his erection didn't subside. Far from it, the shame seemed to act like a stimulant, igniting an even greater arousal in him.
* * *
Jinwoo had just finished the dishes and was heading back to his room.
From inside the downstairs bathroom, he could hear the shower running.
The thought of his mom in there, naked and drenching her body, made Jinwoo's cock swell up like it was about to burst.
There was a changing area outside the bathroom, doubling as a laundry room, screened off by a curtain to block the view from the living room and kitchen. But, if you really wanted to, you could peek through at just the right angle.
Through the gaps in the curtain, Jinwoo spotted clothes in the laundry basket. Among them, a striking piece of purple fabric caught his eye.
It was mom's underwear, just taken off.
That purple panty had been cradling mom's pussy just moments ago.
Jinwoo quietly slid the curtain aside and stepped into the changing area in front of the laundry basket.
The sound of water from the shower was louder now.
Through the frosted glass door, he could barely make out the silhouette of his mom's flesh.
Next to the basket on a small table lay a pair of panties and a light purple silk pajama set mom would change into.
Jinwoo looked around the bathroom and the living room once more before taking a deep breath.
Then, he grabbed the panties mom had taken off, cautiously making no noise with his footsteps, and returned to his room, gasping for breath.
He locked the door and sat on the bed.
He freed his throbbing erection, which had seemed ready to burst through his pants.
Placing his cock against the part of the panty that would have touched his mom's intimate mound, he wrapped it around.
The soft touch of the freshly removed panties transmitted directly onto his entire shaft.
In that moment, his mom once again became Jinwoo's slave.
Imagining his naked mom crouching on the changing room floor, he visualized pushing her from behind, forcing her to arch up.
His cock ruthlessly penetrated her pussy, which was thrust back and pressed against the floor.
He wrapped his arms around her waist and rode her relentlessly, shaking her without pause.
It was as if he was trying to start a fire, his large cock ceaselessly rubbing inside her pussy from tip to base.
The moans leaking from mom were no longer dignified or authoritative.
After raping her like that for a while, he let go of her waist and started slapping her ass.
Slap!!! Slap!!! Slap!!!
"Ah!!!"
Mom's moans mixed with screams leaked out.
Unable to hold back any longer, Jinwoo exploded into the panties.
Then came the post-masturbation emptiness.
Wiping off the semen-stained panties with a tissue, Jinwoo felt an irreversible sense of regret.
He balled up the semen-stained tissue and tossed it deep into the trash can, which was nearly full.
Checking the trash can lid to make sure it was closed tight to contain the smell, he put on his pants.
He stuffed the cum-soaked panties into his pocket.
Then, he just lay sprawled on the bed, overwhelmed with self-loathing.
Recalling the contemptuous look in his sister Sohee's eyes during dinner made him feel even worse.
Jinwoo clutched his head in torment.
* * *
Jinwoo crashed hard after jerking off and dozed off for a bit.
When he woke up, it was nearly 10 PM.
It was the hour when usually everyone in Jinwoo's family would be asleep...
Fumbling with the panties in his pocket, he confirmed this wasn't just a dream.
The thought of returning his mom's panties to the laundry basket spurred him to get up.
He needed a shower too. Grabbing a fresh pair of boxers, he cautiously opened his door and peeked outside.
The coast was clear, so he tiptoed down to the laundry room on the first floor.
The clothes previously in the basket were now in the washing machine.
He buried his mom's panties among the other laundry in the machine.
Stripping off his clothes, Jinwoo tossed them into the washer and headed for a shower in the bathroom.
Showering, he replayed the day's events in his mind:
Daeho spanking Aunty Gyuri's ass at his place,
Masturbating for the first time thinking of his mom when he got home, Getting busted by his sister Sohee while eyeing mom's ass in the kitchen, And sneaking mom's panties out for another round of jerking off...
He felt completely drained, as if he had poured out all his energy.
Yet, there was a strange sense of fulfillment, like he had tamed all his raging urges.
After the shower, he dried off with a towel.
Thinking everyone was asleep, he walked out of the changing room in just his boxers.
That's when he saw his mom coming out of the master bedroom, carrying Minji.
"Jinwoo, are you just out of the shower? It's late, try to do it earlier next time," his mom noticed him and commented.
"Uh... mom... yeah, I just finished showering," Jinwoo replied awkwardly.
He was embarrassed not only because he was only in his underwear but also because there was a stark contrast between the mother he had imagined earlier and the one he was facing now.
"Didn't I tell you before not to wander around the house in just your underwear?"
"Sorry, I thought everyone was asleep."
"Minji and Sohee are here too, you know. You're not a kid anymore, Jinwoo. You're in second grade at the junior school," she reminded him.
"Yeah, I got it. I'll be careful, mom."
As Jinwoo grew up, the house rule had changed; roaming around in underwear became frowned upon.
Until he had started at the junior school, it was common to see family members lounging around in their underwear. Neither Sohee nor Minji had any qualms about it, and the same went for both parents.
Reflecting on it, Jinwoo remembered his oldest sister, Yejin, wandering around in her underwear until she was almost in her second year of senior school.
He even had memories of Yejin, post-shower, braless with her breasts exposed, nonchalantly walking around the house; even in front of dad.
Jinwoo hadn't questioned the different standards between parents and children or among siblings much as he grew up.
"But you're moving Minji to her room?" Jinwoo asked, seeing his mom holding Minji.
"Yeah, could you open her room door for me?" his mom requested.
Jinwoo quickly went ahead, opened Minji's room door, and turned on the light.
Watching his mom tuck Minji into bed, Jinwoo asked, "Aren't you going to sleep together tonight?"
His mom sighed a little and said, "Sleeping together is only sometimes, you know? It's uncomfortable for me if someone is beside me. Plus, Minji insists on sleeping with the lights on in the master bedroom. It keeps me from sleeping deeply all night. Minji needs to start sleeping alone now! Oh right, you went to Gyuri's today, didn't you?"
Caught off guard by her sudden recall, Jinwoo responded awkwardly, "Uh... uh... yeah..."
"Weren't you supposed to borrow an eye mask from Gyuri? I thought you'd have mentioned it if you were going."
"A eye mask?"
"Yeah, since Minji sleeps with the light on, it might be necessary for a while. Gyuri has a lot of those things," she explained.
Jinwoo's heart raced as he remembered the BDSM tools Daeho had mentioned Gyuri owned.
"Gyuri is coming over this weekend anyway, but since I need it now, could you stop by her place after school tomorrow and pick it up? I'll talk to Gyuri in the morning."
"Yeah, sure. I'll go over after school tomorrow," Jinwoo replied, a bit excited by the unexpected plan involving Aunty Gyuri.
"Phew, Minji is getting so big, it's getting hard to carry her," his mom said as she settled Minji in.
"That's kids for you—they grow up so fast," Jinwoo responded, echoing his mom somewhat mechanically.
"Ha-ha, if someone heard you, they'd think you were Minji's dad. You're only about 3 years older than her, right?"
His mom teased him playfully using formal language, finding Jinwoo's mature tone amusing.
Even though it was just teasing, hearing his mom suddenly use formal speech made Jinwoo feel a strange emotion.
Plus, being called Minji's dad—wasn't that indirectly calling him her husband?
A peculiar thrill surged through him, distinctly different from the excitement he had felt during his earlier masturbation.
"But still, you're Minji's brother, so keep looking out for her, okay?" his mom said, gently stroking Minji's head as she slept.
It seemed she was increasingly worried about Minji's excessive attachment to her.
"Don't worry, mom! I'll take good care of Minji," Jinwoo reassured her, wanting to ease his mom's concerns.
"Then, in that spirit, why don't you start moving Minji to her room at night?" his mom suggested.
"Huh?"
"You're up late anyway, right? By this time, Minji is usually asleep. Come and turn off the lights in the master bedroom. Let's do it that way. It's not hard, and it'd be a big help to me," she explained, the playful tone blending into a genuine request.
It wasn't a difficult favor to ask.
In fact, it seemed almost lucky to Jinwoo; getting to see his mom's sleeping figure every night.
"Yeah, sure, mom," Jinwoo quickly agreed, pleased with the arrangement.
That's how Jinwoo ended up visiting the master bedroom nightly to move Minji.
