"Ah, really, what is it?" Si-woo became frustrated and spoke in a whiny tone.
"You don't need to know!! If you're done with your ramen, go do the dishes!!!" Se-hee's irritated command left Si-woo with no choice but to go do the dishes.
Se-hee and Shin-bi sat on the living room sofa, watching TV and chatting. Si-woo perked up his ears, trying to eavesdrop on their conversation, but no mention of 'that' came up. While doing the dishes, Si-woo thought to himself.
'There's something going on. It was definitely about dieting, but why would my sister get angry if I knew? Is it some kind of exercise that's embarrassing to tell your own brother? Ah, it's even more intriguing when even Shin-bi keeps it a secret.'
As the dishes were nearly done, Se-hee, who had been chatting with Shin-bi in the living room, got up to go to the bathroom. Shortly after Se-hee left, Shin-bi approached Si-woo in the kitchen.
"Need help with the dishes?" Shin-bi's voice was serious, without any playfulness.
"It's almost done; it's okay. But wasn't what you were talking about during the ramen about dieting?" Si-woo quickly asked, hoping she might answer while Se-hee was away.
"Yeah, that's right," Shin-bi answered straightforwardly.
"But why would Se-hee get mad if you tell me about the diet?"
"There's such a thing, hehe," Shin-bi didn't give a clear answer.
"Ah, really, even you, Shin-bi?"
"Sorry, but if I tell you, Se-hee really might get mad." Shin-bi kept the secret till the end.
"You're too much; what's the big deal? You were just teasing me earlier, and now you're excluding me, just the two of you. We've known each other for so long! Can't you just tell a close brother a little?" Si-woo appealed to Shin-bi one last time, expressing his disappointment.
Shin-bi looked troubled. "Don't be too upset." After a moment of thought, she spoke. "I can't tell you because Se-hee would really get mad, but I'll give you a hint instead."
As she said this, Shin-bi began writing numbers with her finger on Si-woo's back as he did the dishes.
'0'
'1'
'3'
'5'
After writing the numbers, Shin-bi swept her hand over Si-woo's back as if to erase them.
"0, 1, 3, 5?"
Confused, Si-woo turned his head slightly to confirm with her.
"Shh!"
Shin-bi gestured for silence, making a quieting sound with her mouth.
Si-woo nodded, understanding. He didn't say another word, pondering the answer in silence until Shin-bi left.
Shin-bi left, and afterward, Se-hee went to take a shower, saying she'd go first. Si-woo sat on the living room sofa, pondering the answer Shin-bi had given him. "0135" didn't ring any bells, but Shin-bi had mentioned that if she told him the answer, Se-hee would get mad. He was certain the number had something to do with dieting.
Just then, the front door opened, and Mom and Se-young walked in together.
"Oppa, we're home!"
Se-young called out excitedly as she stepped inside.
"Si-woo, everything okay today?"
His mother greeted him warmly. It was already past 8 PM.
"Yeah, nothing much happened. You two are home late tonight."
Si-woo thought back to the day's events—spanking Gyu-ri for the first time, catching his sister smoking and acting rebellious, and discovering the tattoo on her inner thigh. None of these were things he could mention.
"Is Se-hee in the shower?"
"Yeah."
"Did you eat?"
"I had ramen with Noona."
"I told Se-hee to make sure you had a proper meal. There was rice and side dishes in the fridge. Why did she only make ramen?"
His mother grumbled.
"No, it was nice to have ramen for a change."
"Still, you should eat real meals when you can."
Seon-mi's tone carried its usual strictness about proper meals.
"So, where did you and Se-young go today?"
Si-woo asked, curious. It wasn't like Seon-mi to take just one of them out for so long.
"Se-young and I had a date today."
"A date? What's that about?"
"Mom and I are in love, aren't we, Mom?"
Se-young wrapped her arms around Mom's waist, grinning.
"Sure, let's get married and have lots of kids."
"We can't have kids because we're both girls. But we'll take care of you and Se-hee unnie."
"Young stepmom, huh? Weird."
Si-woo teased. Se-young laughed, clearly enjoying the playful exchange.
"Did you two eat out?"
"Yeah, we did."
"Dinner's a must on a date!"
"Did you visit Gyu-ri's place?" Mom ran her fingers through Se-young's hair before turning to Si-woo.
"Yeah, I did. I'll grab the eye mask from my room."
Si-woo had already received a thank-you text from Gyu-ri earlier, so he wasn't worried about his mother getting on his case. He went to his room, grabbed the shopping bag containing the lavender silk eye mask Gyu-ri had given him, and brought it to the master bedroom. Handing over the bag, he noted how innocent the gift seemed despite its potential for other uses, a thought he quickly pushed aside.
***
As Si-woo approached the master bedroom, he overheard his mother and Se-young talking.
"Mom, I want to do it now."
"No, your brother will be down soon."
"It'll only take a minute, Mom. Please?"
"Remember, we promised the teacher we'd stick to the schedule? And we just got home and haven't showered yet. Let's do it after we clean up, okay?"
"Okay." Se-young reluctantly agreed.
Si-woo decided it was best to act as if he hadn't heard anything. Clearing his throat, he stepped into the room and found Se-young clinging to their mom, her face buried in her chest. He handed his mother the eye mask.
"Mom, here's the mask Aunt Gyu-ri sent."
"Thanks, Si-woo. Oh, and you didn't forget about last night's request, right?"
Si-woo recalled Seon-mi asking him to ensure Se-young went to her own room after falling asleep in the master bedroom. He saw it as a fortunate opportunity and had been looking forward to it.
"I remember. I'll handle everything, so you can sleep comfortably."
"Thanks, Si-woo. You're a big help."
***
Si-woo left the master bedroom and headed to his room, but on the way, he ran into Se-hee, fresh from her shower and wearing the same pink hot pants she'd had on the morning before.
"Did Mom tell you?"
"Tell me what?"
"About Se-young."
"What about her?"
"Never mind." Se-hee shrugged as if something had just occurred to her, then turned and walked upstairs. Her toned legs and calves were on full display, the pink shorts clinging to her hips.
"What the hell is going on?"
Si-woo stood there, his frustration mounting. The secrecy surrounding Se-young and Shin-bi's cryptic task was beginning to wear on him.
***
Returning to his room, Si-woo vowed to uncover his sister's secret at all costs. He jotted down the strange numbers Shin-bi had whispered earlier—"0135"—and stared at them, his mind spinning.
"Eternal love? Or a local code?" Adding, subtracting, multiplying, dividing—he tried everything, but nothing made sense. Frustration gnawed at him. Pride didn't matter now; he needed answers to shake off the unease consuming him.
Desperate, he messaged Cheol-jin with little expectation.
"Any idea what 0135 means?"
A reply came almost immediately.
"What the hell are you talking about?"
Si-woo explained everything—meeting his sister's friends outside the house, the cryptic conversation over ramen, and how Shin-bi had written the numbers on his back.
"So Shin-bi noona really wrote that on your back?"
"Yes!"
Cheol-jin seemed to grasp the situation.
"Hold on."
Ten seconds later, Si-woo's phone rang. Cheol-jin's excited voice erupted through the speaker.
"Dude, what the fuck, is this for real?!"
"What? Why are you freaking out?"
"If you know, you won't sleep tonight."
"Just tell me already!"
Cheol-jin took a breath and started explaining.
"First, convert the numbers to digital form."
"Okay."
"Now, flip them all upside down."
"The 3 becomes an E."
"Right, so 0135 flipped is 5E10."
"Then 5 turns into S, making it SE10."
"And 10 is X in Roman numerals."
"Put it all together. What do you see?"
"Holy shit!" Si-woo stared at the numbers, speechless.
"S E X."
"Is this real?"
"Yeah, I should be asking you. Did Shin-bi noona really write that on your back?"
"Yes, she did."
"Then can I jerk off thinking about Shin-bi noona and your sister tonight?"
"Dude, are you insane? No! And why would you even ask me for permission?"
The back-and-forth dragged on before Si-woo finally hung up, his thoughts swirling. This was the first time he'd seen Se-hee and Shin-bi act so recklessly. Until now, they had just been his flirtatious sister and her pretty best friend. But from now on, he knew he wouldn't be able to see them the same way.
"It's a world made of sex anyway. What's a bit more indulgence going to change?"
As 10 o'clock approached, it was time for Si-woo to go downstairs and move Se-young to her room.
His enormous erection, which had been throbbing with excitement over his sister, finally calmed down after a long effort. But soon, Si-woo realized all that effort was pointless.
Si-woo carefully entered the brightly lit master bedroom on the first floor. His task was simple: move Se-young to her room, as he had discussed with his mother. Although he had ulterior motives when he agreed to help, they weren't sexual in nature. Si-woo intended to carry out his mother's request sincerely.
He had no idea what was happening. Nor could he foresee what would happen next. He simply walked in on it.
The bright LED light filled the room, illuminating everything. His mother lay on her side, wearing an eye mask to block the brightness. Her round, white breasts were partially exposed through her light purple silk gown. Her soft, voluptuous breasts were fully exposed, showing their natural, lush beauty. At the tip of each breast, the nipples stood out, with one of Se-young's small lips gently wrapped around one of them.
It was a scene Si-woo had never imagined. It was hard to believe, even as it unfolded before his eyes. He stood there for a while, mesmerized, before snapping back to reality.
He cautiously called out to his mother, "Mom? Are you asleep?"
There was no response from her.
Si-woo slowly detached Se-young's lips from his mother's breast. Even in her sleep, Se-young instinctively sought her mom's nipple, her lips moving slightly. His mother's nipple and the surrounding skin were slick with Se-young's saliva, glistening in the light. Si-woo's erection hardened again instantly, feeling like it would explode. His head spun.
"Mom?"
He called again softly, but waking her would be trouble for him. If she saw his erect cock, what could he possibly say? Despite the risk, he needed to confirm she was sleeping.
Si-woo had come down to move Se-young as his mother had asked. Before him lay his mother, with Se-young sucking her breast, the nipple shiny with saliva. Yet, he felt compelled to ensure his mother was asleep. After a moment of hesitation, he reached out and touched her breast.
Her nipple, wet from Se-young's saliva, was firm. Si-woo's finger lightly pressed and twisted the nipple before letting it spring back. The taut, inviting nipple bounced, and his mother's body twitched in response. Si-woo's heart nearly stopped. He dropped to the floor, hiding. His heart pounded like it would burst from his chest, overwhelming excitement coursing through him.
Was she awake? Or was it just a reflex to the touch? He couldn't tell with her eyes covered. After a while, he cautiously stood up, relieved to see she still seemed asleep. He couldn't comprehend what he had just done—flicking his mother's nipple, wet with Se-young's saliva. It was an instinctive, bizarre act he had neither seen nor heard of before.
He had come here with pure intentions, to help his mother by moving Se-young to her room. Suppressing the urge to flick his mother's nipple again, Si-woo regained his composure. He needed to finish what he had come here to do before anything else happened.
Gently, he lifted Se-young, making sure not to wake her. He positioned her arms over his shoulders and supported her butt and back with his arms, holding her close, their bodies pressed together, allowing him to feel every part of her against him. He gently caressed her back and then squeezed her ass, feeling the warmth and texture of her flesh. Pressing her ass firmly against his crotch, he felt a delightful jolt of pleasure from his throbbing cock.
Worried that his mother might wake up anytime soon, Si-woo quickly carried Se-young out of the master bedroom. Se-young, already in the fifth grade, felt different now, with her breasts, ass, and thighs starting to fill out.
A wave of guilt washed over him, spreading like an electric current through his body. He walked as slowly as possible, savoring each moment until they reached Se-young's room. He laid her on the bed, her warmth and the sensation of her skin still lingering on his body. Se-young was a fast sleeper, her breathing soft and steady. Her face reminded him so much of her mother, and he couldn't help but wonder if her body would develop just as beautifully.
Si-woo's hand moved to Se-young's chest, feeling the softness of her budding breasts through her clothing. He imagined them growing to be as large and tempting as her mother's. Her silky hair fell just below her shoulders, and her pale skin and light pink lips were mesmerizing. He remembered those lips nursing from her mother's breasts, now slightly parted as she slept.
Si-woo felt an overwhelming urge he couldn't resist. He brought his lips to hers, feeling their softness and warmth. Almost unconsciously, he licked her lips and fondled her chest, tasting the sweetness of her mouth. A soft moan escaped Se-young's lips, and Si-woo froze, realizing what he was doing. He had groped Se-young's breasts and stolen a kiss from her while she slept.
Fearing what he might do next, Si-woo quickly retreated to the bathroom, his cock painfully hard. He couldn't bear to look back at Se-young, overwhelmed by the guilt of what he had done to her and her mother. But even as the guilt consumed him, he felt it fuel his lust.
His mind burned with images of his mother's breasts and Se-young's lips. He rummaged through the laundry, searching desperately for Se-hee's black panties. Finally, he found her panties, damp with sweat, clinging to her buttocks. The sour, fishy smell of Se-hee's sweat hit his nose.
Trembling with excitement, Si-woo wanted to release his pent-up lust quickly. Se-hee's panties seemed perfect for his filthy desires. He wrapped his huge cock in her panties and began stroking himself furiously.
In his mind, Se-hee was bent over, her curvy ass presented to him, begging for mercy as he thrust into her with his huge dick, her juices dripping down her thighs. He came hard, flooding the panties with his cum, shaking with the intensity of his release.
Si-woo shuddered with guilt after his climax, realizing the depths of his depravity. But even this guilt was being consumed by his burning lust. He was on fire, thinking about his mother's breasts and Se-young's lips.
That morning…
Seon-mi told her son, Si-woo, who was getting ready to leave for school.
"I called Gyu-ri. She said she'll be home in the afternoon, so you can swing by and pick up the sleeping mask after your class."
"Got it! I just need to grab the mask. I'm going!"
Si-woo nodded as he headed out the door.
"Yes. Take care~!"
With her children off to school, Seon-mi finally found herself alone. The chaotic morning routine had come to an end, leaving the house eerily quiet. To fill the emptiness, Seon-mi busied herself with household chores. She headed to the laundry room and started a load of washing. Moving to the kitchen, she cleaned the table and did the dishes.
Afterward, she began cleaning the house, moving through the living room, kitchen, laundry room, and master bedroom, finally tackling the stairs and hallway. She left her children's rooms untouched, respecting their privacy; the only thing she did was empty their trash bins. This was part of her educational philosophy—to respect her children's personal space.
Once the cleaning was done, she retrieved the laundry from the washer and hung it out to dry. Only then did she allow herself a brief moment of rest. Seon-mi had been a stay-at-home mom for nearly 20 years, diligently repeating these tasks almost daily.
Afterward, she headed to the bathroom to wash away the sweat from her labor. The bathroom had a small dressing area shared with the laundry room. As she undressed, she glanced at her lavender panties hanging on the drying rack.
Seon-mi had recently noticed that Si-woo had started masturbating.
The scent of semen emanating from his trash bin and his less-than-thorough cleanup hinted at it. It seemed even his sister, Se-hee, had picked up on it. Her suggestive morning clothes and teasing with sexual jokes, though meant in a sibling context, seemed to provoke the same reaction.
Seon-mi was aware that her son's cock responded to her; she became increasingly conscious of her attire at home. She always tried to dress modestly around the house, opting for simple, unassuming clothing. Despite her efforts, she knew that the panties she had taken off last night had disappeared, and Si-woo had used them for masturbation. The smell of male cum on her underwear confirmed her suspicion.
While Si-woo was unaware, Seon-mi made sure to change the trash bag in his room daily, noting that the amount of tissues today was much more than usual, and the smell was particularly strong. She thought it was natural to feel aroused when exposed to accidental stimuli, even if it involved family members. However, intentionally seeking sexual excitement from a family member was a different matter, one that made her anxious and irritable.
Entering the bathroom, she stood under the shower and let the water drench her body. She applied body cleanser to a shower towel, creating a lather before rubbing it over her skin. She moved her hand from her breasts to her belly and sides, finally reaching her crotch. She positioned her middle finger between her pussy lips and rubbed up and down before finding her hole and sliding her finger inside. With her thumb, she circled her clit, stimulating herself with practiced ease.
This private time of release was precious to Seon-mi, a sweet reward after a diligent morning's work. She had always had a strong sex drive; even when her husband was alive, she often enjoyed these secret moments of pleasure alone. Even when her husband had an affair, even when she discovered the other woman was their oldest daughter, and even when her husband died without resolving anything, Seon-mi continued her compulsive masturbation to maintain her image as a perfect mother.
For her, these moments of release became her way of finding balance in life. This secret pleasure was not just an escape but a necessary ritual, akin to religious meditation. It helped her release tension and maintain her role as a devoted mother.
Reaching her climax, Seon-mi let herself collapse onto the shower floor, savoring the lingering pleasure. She made sure to leave no trace behind.
***
It was early afternoon when Seon-ju, Seon-mi's younger sister, dropped by after lunch. Seon-ju, who was only a few years younger than Seon-mi, was a single mother with a daughter named Soo-ah, who was the same age as Se-young. Seon-ju knew about her late brother-in-law's affair and that the other woman was Se-jin. She was one of the few, alongside Gyu-ri, who shared Seon-mi's secret.
Seon-ju often visited Seon-mi's home, as they had always been close and lived nearby. Since her brother-in-law's death, Seon-ju had been particularly attentive to her sister, aware of the circumstances involving him and Se-jin.
As they chatted over tea, the conversation shifted to Se-hee's clothing choices.
"It's normal for family to feel comfortable at home. A little skin isn't a big deal. Se-hee's handling it just fine."
Seon-ju smirked, defending her niece.
"She's just messing with Si-woo!"
Seon-mi shot back, the memory of his flustered reaction earlier making her laugh.
"If you keep being so uptight, that boy's just gonna get even more worked up over the smallest things. Didn't you say he started jerking off with your panties? Might as well help him out the way Se-hee does."
Seon-ju teased, watching her sister get flustered.
"Hey, Si-woo is my son! Are you going to take responsibility if something happens again?"
Seon-mi snapped back. The seriousness in her tone made Seon-ju stop teasing immediately.
They both understood the weight of what she had said, the "again" a painful reminder of what had happened with Se-jin. For a moment, they were both silent, the air heavy with unspoken thoughts.
Finally, Seon-ju broke the silence, looking at her sister with concern.
"Se-jin still hasn't been coming home? Still ignoring your calls?"
"Yeah… She took a break from university and started working part-time. I only hear about her through Si-woo…"
Sadness flickered in Seon-mi's eyes, betraying her attempt to appear composed.
"You should go see her. Talk it out. You can't keep letting this drag on."
"It's awkward, okay? Let's not get into it."
She shifted uncomfortably, brushing off the suggestion.
Seon-ju shared many secrets with her sister, but she could never fully grasp Seon-mi's feelings. Seon-mi had forgiven Se-jin in her heart countless times; no matter what Se-jin had done, she was still her daughter. Yet forgiveness wasn't what Se-jin wanted—she sought acknowledgment of her relationship with her father, a recognition Seon-mi couldn't bring herself to give.
They spoke for another half hour before Seon-ju decided it was time to leave.
"Alright, I'll see you this weekend with Gyu-ri-unnie. Bye!"
She gave a playful wink and headed out the door.
***
Seon-mi had scheduled a psychiatric appointment for Se-young today. Recently, Se-young had trouble falling asleep alone, which worried Seon-mi, though she also felt pressured by the constant interruptions to her private moments. Se-young had started insisting on touching her mother's breasts and nursing, which Seon-mi reluctantly obliged a few times. The physical arousal it caused was unpleasant, and Seon-mi tried various ways to calm Se-young, but her clinginess only grew worse.
Seon-mi sent Se-hee a text, informing her about the appointment and reminding her to have dinner with Si-woo. She didn't mention that the outing was for a psychological consultation. She took a taxi to pick up Se-young from school, arriving just as classes ended. Se-young had been told about the appointment the day before and waited quietly at the gate.
On the way to the hospital, Se-young was unusually silent, clearly anxious. Once at the hospital, they checked in and went straight to the consultation room. The examination and counseling took a while, with Seon-mi present throughout. The doctor diagnosed Se-young with anxiety disorder, explaining that she exhibited signs of regression. He advised setting aside specific times for her to act like a baby, including nursing if necessary, rather than scolding her.
Se-young seemed quietly pleased with the advice, though she didn't say much. Seon-mi wasn't opposed to nursing Se-young, but she struggled with the arousal it caused. As they left the hospital, the sky had already darkened. They took another taxi to a cozy restaurant, one of Se-young's favorite spots.
As they settled into their seats, Se-young eagerly ordered her preferred dish: a chicken breast and egg rice bowl. Throughout the meal, Se-young clung to her mother, occasionally burying her face in Seon-mi's soft, ample chest. She behaved like a delighted child, savoring every moment of being indulged. Seon-mi, finding her daughter's innocence utterly adorable, decided to let Se-young have her way.
Chapter 12
After Seon-mi and Se-young arrive home.
"Alright, we promised to set a time with the doctor, remember? We just got home and haven't showered yet, so let's do that first, okay?"
Seon-mi soothe the whining Se-young.
Seon-mi received a sleeping mask from Si-woo before she went to her room. Then, she grabbed her panties and a light purple silk nightgown and headed to the bathroom.
In the dressing room next to the bathroom, Seon-mi placed her panties and nightgown on a small table.
She emptied the laundry basket into the washing machine, adding the rest of her clothes and underwear.
As she showered, she couldn't shake the awkward feeling that came with nursing her fifth-grade daughter, Se-young. Even though she wasn't producing milk, it would look strange to anyone watching. She had reluctantly complied with Se-young's persistent pleas before, but this was the first time they had set a specific time for it.
After finishing her shower, Seon-mi told Se-young to go wash up. She put on a blindfold and lay down on the bed, finding it less awkward not to see her own face. A few moments later, Se-young returned from her shower and nestled into Seon-mi's arms. Seon-mi lay on her side, cradling Se-young's head with her left arm and holding her close.
Se-young untied the front of her mother's nightgown, exposing her large breasts. She took a nipple into her mouth and sucked gently. Seon-mi felt a tingling sensation from the warm, slick feeling of Se-young's mouth. The blindfold seemed to heighten her senses, making everything more intense.
Se-young grabbed her mother's other breast, pressing it against her face.
"Slow down, Se-young. There's no milk, but do you really like Mommy's boobs that much?"
Seon-mi tried to hide her embarrassment with small talk.
"Hehe, Mommy's boobs are so pretty. I feel good. I want to do this forever."
Se-young mutter innocently, sucking harder.
"Se-young, if you suck like that, you'll wear out Mommy's nipples,"
Seon-mi sighed, trying to cover up her increasingly ragged breathing.
"Does it hurt?"
Se-young asked, slightly releasing the nipple, a string of saliva connecting her mouth to the nipple.
"No, it doesn't hurt. But sucking that hard is tiring for Mommy. Just be gentle, okay?"
Seon-mi soothe, stroking Se-young's hair.
"Okay, I'll be gentle."
Se-young carefully resumed sucking, and the slow, deliberate motion of her mouth on Seon-mi's sensitive nipples sent stronger sensations through her. Her face contorted beneath the blindfold.
Seon-mi didn't mind the sensation of Se-young sucking her breasts. The problem was dealing with the feelings without interpreting them sexually. Her body tensed with the effort.
In less than ten minutes, her body felt exhausted from the nursing session.
'I need to wrap this up before Si-woo comes down…'
She began to drift off, lulled by the tender sensation. Just before Si-woo walked in, she woke up to the sound of footsteps approaching the master bedroom.
Her eyes opened, but she saw nothing through the blindfold. Se-young's face and lips were still attached to her breast. The bedroom light was probably on, exposing her bare breasts.
Si-woo entered and stopped, staring. Even though she couldn't see him, she felt his gaze on her chest. Her heart raced.
Considering that Si-woo had masturbated with her underwear, it wouldn't be surprising if he got an erection from seeing her exposed breasts. In fact, she was certain he was aroused.
"Mom? Are you asleep?"
Si-woo's cautious voice broke the silence.
She didn't want to get up and face him with her breasts exposed. She could explain everything later. Telling him about Se-young's diagnosis and treatment would make him understand.
It wasn't a problem if he saw her breasts. She just wanted to get out of this situation.
While she was thinking, Si-woo gently pulled Se-young away from her. Se-young's mouth dragged across her stiff nipple, sending a shiver down her spine.
Seon-mi almost let out a moan but managed to suppress it. Her wet nipple was exposed to the cool air, and the fresh sensation made it stand erect again. Si-woo's gaze felt even more intense.
"Mom?"
Once again, Si-woo called out to Seon-mi in a low voice.
Just hearing Si-woo's voice made Seon-mi's body heat up. She forced herself to suppress the trembling.
If she remained silent, Si-woo would soon leave the room with Se-young, and everything would be over.
"It'll all be over then,"
she thought, trying to endure.
Suddenly, a jolt of sensation spread from her nipples to the back of her neck. Si-woo's fingers had touched her sensitive, erect nipples, rubbing them before flicking them with a snap.
Seon-mi was startled and her body involuntarily jerked. A powerful vibration seemed to travel from her nipples, up her spine, and throughout her body. The sudden act of her son made her dizzy.
Her mind was filled with thoughts of how to handle what was happening. Si-woo, unable to control his desire, would soon force himself on her. She'd have to stifle her moans so as not to wake her daughter sleeping nearby. The image of her accepting Si-woo without resistance filled her mind.
The impending humiliation, helplessness, and shame from her son overwhelmed her, making her vision blur. But then, nothing happened.
After a moment, Si-woo left the room, carrying Se-young. Relief washed over her, followed by a strange sense of emptiness.
She was startled by the realization that she might have been expecting it—expecting her son's advances.
Even after the door closed, her mind was still in turmoil.
The memory of her son's gaze on her erect nipples and his fingers touching them was seared into her brain. She couldn't help but wonder what might have happened if she hadn't been blindfolded.
'Was I hoping my own son would rape me?'
She didn't know.
'Why am I so wet down there? Am I really that pervert?'
She shook her head, trying to calm herself. After a while, she sat up and removed the blindfold.
She was relieved to see that Si-woo had indeed carried Se-young to her bedroom.
A while later, she heard the sound of Si-woo taking a shower. Seon-mi lay on her side, her chest exposed, unable to move. The thought of Si-woo returning to continue his advances filled her with a strange excitement.
Without being touched,
Seon-mi felt herself getting even wetter without being touched. She was so wet that she had dampened the bed beneath her. Moisture trickled down her thighs and ass as her body trembled. Her breasts were exposed, and she couldn't move. Or perhaps she didn't want to move.
It was a new, unfamiliar arousal. The cold air around her felt like hands caressing her breasts. The realization that she was waiting for Si-woo, coupled with the sense of being abandoned, left her feeling bound and unable to move.
The sound of the shower stopped, and time passed. It was only then that she felt like she could move again, as if waking from a trance. Seon-mi hugged her chest, trembling. She knew she couldn't just sleep it off.
Feeling a mix of dread and curiosity, she took off her blindfold and quietly went to the laundry room. The faint smell of semen lingered. She opened the washer and saw Se-hee's panties, stained and wet, on top of the laundry pile.
For a moment, she stood there, stunned. Did Si-woo not realize she was the only one who did the laundry? The panties, clearly stained with semen, were left in plain sight. And they weren't hers.
A peculiar shame washed over her. Seon-mi picked up Se-hee's panties and sniffed them. The combined scents of Se-hee's sweat and Si-woo's potent musk filled her nose.
Her body trembled again.
She brought the panties back to her room, put her blindfold back on, and lay down. She left the light on and the door slightly open, wanting to maintain the strange excitement.
The strong smell of Si-woo's semen and Se-hee's lingering scent filled the room. Holding the panties in one hand, she inhaled deeply, indulging in a new nighttime pleasure, separate from the day.
She rubbed her clit with her fingers. What would Si-woo think if he saw his mother like this? Or Se-hee or Se-young?
Imagining such scenarios made her pussy twitch with contractions. Anyone passing by the open door could see her, the room illuminated by the light.
Blindfolded, sniffing Si-woo's semen-stained panties, Seon-mi reached her climax, unaware of any onlookers.
