It was dawn the next day.
"Jinwoo, wake up, Jinwoo~~!!!"
Sohee frantically shook Jinwoo to wake him up.
"Huh? What's up? What's going on, noona?"
Jinwoo, groggily waking up, speaks while looking at Sohee, who isn't acting like her usual self.
"I feel like someone's been following and watching me!!"
Noona said to Jinwoo with a face full of fear.
"Come on, what are you talking about? You woke up and started rambling. You didn't have a nightmare, did you?"
Initially, Jinwoo thought that Sohee was making a fuss over him due to the shock of getting scolded by their mom the day before.
"No, I'm serious!!"
Thump!
"Hurry up and get up!!"
Thump!
Noona said while hitting Jinwoo's chest as he lay in bed.
"Ow, noona, that hurts."
Jinwoo grabbed Noona's wrist to stop her and got up.
"I've had a weird feeling since yesterday!! I think someone took a picture of me!"
"What?"
Seeing noona's serious demeanor, Jinwoo starts listening intently.
"I usually don't mind when strangers take pictures... but yesterday, I think that person followed me all the way home!"
"He followed you home?"
"Just now, when I went out for a jog, some sketchy dude saw me and I started freaking out, hiding in an alley~!"
Jinwoo began to worry upon hearing noona's words.
If someone really did follow her home, the situation was getting serious.
"Did you see his face?"
"No, he was wearing sunglasses and a mask, so I couldn't see."
"Hmm..."
After pondering for a moment, Jinwoo spoke.
"Should we call the police?"
"How can you report something like this?!!"
Noona, clearly frustrated, snapped at Jinwoo.
"So, what do we do then?"
Jinwoo, clueless, scratched his head and looked at Sohee.
Sohee looked back at him with blurry eyes as if he was pathetic.
"I'm gonna be cut off from my allowance for two weeks because of you!!"
-Jinwoo's half allowance-
"Uh..."
"Think about paying me back!!!"
"What?"
Jinwoo felt that something was going wrong.
"Be my bodyguard for two weeks!!"
And so, Jinwoo ended up following Sohee on her morning jogs and to and from school under her coercion.
* * *
Leaving the house and running along the riverside jogging path, Noona wore a black slim-fit hooded jacket and skin-tight leggings.
Watching the professional sight of noona's back as she cut through the morning air, Jinwoo could understand and somewhat empathize with the suspicious character following his sister, from a purely male perspective.
He also realized that as long as she could keep running, there was no way Sohee would get caught by someone and suffer any harm.
In front of the park
Gasping for breath, Jinwoo was barely keeping up with Sohee. Unable to go on, he stopped, knelt down, and bent over to catch his breath when he felt an uneasy gaze from somewhere down the residential street leading to their house.
A familiar discomfort
* * *
After jogging, Sohee went to the bathroom on the first floor to shower.
Jinwoo, checking for any remnants of yesterday, quietly entered the changing room in front of the bathroom where noona went to wash.
The floor was clean, and the washing machine had already been run once.
A proud thrill filled his chest.
As he was about to leave the changing room, he noticed Sohee's underwear in the basket.
Sweaty triangle sports panties
Jinwoo absentmindedly picked up Sohee's sports panties and slipped them into his pocket.
He opened the changing room curtain and came out.
Mom and Minji were starting to prepare breakfast in the kitchen.
And mom's eyes met his.
"Oh? Jinwoo, you're up early today too? Is Sohee using the shower now?"
Mom greeted him with a smile, as usual.
She must have seen Minji's panties stained with Jinwoo's semen...
She had wiped it off and put it in the washing machine...
And had kneaded and rubbed her breasts and ass...
And had gotten the same feeling in her ass as when Sohee was being hit...
And had Jinwoo suck on the same breasts that Minji had been sucking on...
She was pretending not to know and greeting Jinwoo as usual.
Their lascivious and secretive secrets were shared with an implicit and deceptive attitude.
And those sharing the secrets were none other than mother and son.
Jinwoo felt a thrilling sense of superiority.
* * *
At breakfast, Sohee's clothes were ordinary.
There seemed to be a slight awkwardness between mom and Sohee after the big scolding Sohee received from mom the night before. However, as they exchanged normal conversation, the awkwardness gradually faded.
"Did you take Jinwoo jogging this morning?"
Mom asked Sohee.
"Yeah, I woke him up and we went together."
Sohee cautiously replied to her mom.
"That's good to hear. How nice is that? Sohee, you should teach Jinwoo some exercise routines. Jinwoo, you should also take this chance to work out with your sister!"
Mom seemed to be in a particularly talkative mood, possibly trying to ease the remaining tension.
Then she naturally continued the conversation.
"Is the place where you got hit yesterday okay? I hope it doesn't scar too much."
Mom gently placed her hand on Sohee's shoulder, speaking in a friendly tone.
"Yeah, it's fine. Just a little bruised."
Sohee smiled slightly, reassuring her mom.
"That's good. I was a bit too heated yesterday. Sohee, you were quite upset, weren't you?"
Mom's hand was soothingly stroking Sohee's back, just as she had to console her the day before.
"No, it's okay. Everything got sorted out in the end since you understood how I felt."
Sohee felt the comforting touch of her mom's hand and spoke amiably.
"That's why, after thinking about it, I think it was too harsh not to give Sohee her allowance for two weeks... I'm going to start giving it again."
Mom spoke softly to Sohee about reinstating her allowance.
Then
"!!!~Mom, thank you~~ I'll really listen to you from now on!"
Sohee exclaimed joyfully and hugged her mom.
Mom hugged Sohee back, smiling contentedly.
Jinwoo felt a slight embarrassment from his mom as she hugged Sohee, and their eyes met briefly.
* * *
Throughout breakfast, Jinwoo was aroused.
He was on the edge, a moment away from exploding with excitement.
He scooted his chair closer to the table to cover himself, but he felt like it wouldn't matter even if he was seen.
Relieved by the thought that his demand (?) from last night - which didn't seem like just a request - had been acknowledged by his mom, Jinwoo felt good.
And seeing mom's eyes avoid his - which didn't feel like a misconception - he sensed a sultry charm.
Sohee and Minji had finished eating and went back to their rooms.
Jinwoo pretended to eat slowly because of his arousal, while mom started cleaning up the dishes.
Mom's back was turned towards the sink, wearing an oversized purple T-shirt and the gray pleated skirt he had seen before. Her shapely ass enticingly visible to Jinwoo.
The tantalizing ass under the pleated skirt swayed slightly in tune with mom's movements as she did the dishes.
Jinwoo, with a throbbing heart, stood up and approached mom.
Then, as if accidentally, he brushed his hand against her ass.
Instantly, he felt mom's ass twitch and tense up, then relax.
The firm elasticity was conveyed directly through Jinwoo's hand.
He glanced sideways and saw mom bowing her head, her face flushing as if embarrassed, but her hands continued washing without pause.
Mom said nothing to Jinwoo.
In that moment, Jinwoo found her incredibly lovely.
His body trembled.
An urge to thrust his erect member into her right there surged powerfully from deep within.
However, remembering that Sohee and Minji were still in the house, he barely managed to suppress the urge.
* * *
Jinwoo headed back to his room, turning towards the staircase.
As he started to ascend, Sohee, who had changed into her school uniform, was coming down from the second floor.
Her blouse under the school jacket tightly wrapped around her bursting breasts, perfectly visible from the diagonal direction in front.
Jinwoo himself had an impressive erection, too late to cover with his hand.
Sohee sighed shortly and then lightly flicked Jinwoo's head with her finger.
Thwack!
Then she quietly said to him,
"I'll wait outside, so hurry up and handle it~!!"
Embarrassed, Jinwoo headed up to his room.
