Sohee came out of the fitting room having changed her clothes.
She was rocking the pink dress that exposed more than half her chest.
The dress clung to Sohee's body, tracing all those killer curves perfectly.
Maybe it was the skimpy outfit, but she had ditched her bra.
You could kinda see the outlines of her cute nipples right through the dress, smack dab in the middle of her lush, full breasts.
Sohee, looking a bit shy, walked up to Jinwoo, mom, and Minji.
* * *
Jinwoo was popping a boner naturally, watching the sensual figure drawn by the pink dress on his sister Sohee.
Right before leaving the house, he regretted not masturbating with the panties Sohee had offered to lend him.
Jinwoo quickly shoved his hand into the pocket of his long cardigan to cover up.
To Jinwoo, it didn't matter anymore if his mom and sister saw him hard.
After all, both mom and Sohee knew about Jinwoo's condition; he kind of wanted to freely show them his erection and see their reactions.
But in front of young Minji, it was a bit tricky.
-Differently from showing himself petting mom's head-
Jinwoo had rubbed his cock against Minji at night while moving her in her sleep, also showing his erection when pretending he was asleep, but that was when either she was unconscious or he was pretending to be.
Being sober and showing an erection in response to Sohee's body was a whole different level.
Seeing Jinwoo hastily cover up, Sohee blushed slightly and approached mom.
"Is this too sexy?"
Originally not planning to pick the first dress, Sohee, feeling the dress was too sexy even for her, cautiously asked mom.
"It does seem a bit... what do you think, Jinwoo?"
Mom glanced at the front of Jinwoo, covered by the cardigan, and said.
"I think it looks great? It really suits noona."
While receiving looks from mom, Sohee, and Minji, Jinwoo replied.
Especially Minji's intense gaze on Jinwoo's thing felt strong.
Nowadays, even elementary school kids start sex education early.
Despite Minji's sexual autonomy and development, the education was enough for her to understand Jinwoo's condition from the erection he was showing in response to Sohee's body.
Jinwoo felt like all his hair was standing up under Minji's gaze.
"You okay, Jinwoo?"
Mom's question seemed loaded with multiple meanings.
"Yeah, I'm fine. I wish mom would wear clothes like this at home..."
Jinwoo responded as if making a request to mom.
"Ah, geez!! How can a old lady wear something like this?"
Mom sighed as if embarrassed in front of Sohee and Minji.
"People would think you're a noona, not a mom, if you walk around with Sohee, right?"
Jinwoo exaggeratedly complimented to lift mom's spirits.
"Really!! Jinwoo, stop teasing mom already!"
Mom grimaced, clearly embarrassed by Jinwoo's compliments, and then raised her voice as if to pour out all her resentment about Jinwoo's harassment and teasing at once.
"Okay~ I got it~ mom~"
Jinwoo playfully responded.
"Well, Jinwoo is okay with it... It does look a bit sexy to mom... but it seems like it would be okay if covered with something... Anyway!! I can't say no when the kids are making such a fuss~"
Mom rambled in an embarrassed tone, suddenly changing her attitude, as if she had no choice but to buy it because Sohee really wanted it.
That's how mom ended up buying the dress Jinwoo wanted for his noona.
* * *
Sohee, having received a paper shopping bag with a luxury brand logo from the store clerk, felt pleased.
She had changed back into her original clothes, but Jinwoo's erection hadn't subsided.
"Here, Jinwoo, you carry this."
Sohee handed over the shopping bag to cover up Jinwoo's front, a mix of gratitude and awkwardness for Jinwoo.
Holding the shopping bag with one hand, which just moments ago had been wrapped around his sister's sexy outfit, Jinwoo felt his thing get even harder.
Suddenly, Minji grabbed Jinwoo's free hand.
Startled, Jinwoo pulled the shopping bag closer to his groin with his other hand.
"Brother!! Stop bothering mom now, hehe~!!"
As if playing the role of a mediator between mom and Jinwoo, Minji held one hand of each in hers and stood in the middle, pleading like she was trying to reconcile them.
-It seemed to Minji that Jinwoo was bothering mom-
Minji, standing close enough to touch, surely knew about Jinwoo's erection just as mom and Sohee did.
The three of them, aware of each other's awareness, either pretended not to notice or tried to cover Jinwoo's erection.
Jinwoo, looking once at mom and then at Sohee, firmly held Minji's hand, enjoying this bizarre situation.
* * *
Jinwoo walked around the huge department store shopping while still erect, but it subsided when he sat down in the café lounge and had a drink to relax.
Mom, saying she would buy underwear for Minji, left Sohee and Jinwoo at the café and headed with Minji to a junior women's underwear store.
Given Jinwoo's state and the fact that it was a women's lingerie store, even if for juniors, it might be awkward, so it seemed a decision was made to go separately, leaving Sohee and Jinwoo behind.
"What happened between you and mom?"
Sohee, sipping her strawberry iced latte, asked Jinwoo.
"Why are you asking? Nothing special."
Jinwoo, recalling last night's events, felt guilty and lied to his sister.
"It seems a bit weird lately."
"Weird? What do you mean?"
"Like when Aunty Gyuri came over today, and when we were buying my clothes earlier... You haven't possibly..."
Sohee looked at Jinwoo intently, pausing deliberately.
"Possibly what?"
Jinwoo, anxious whether his relationship with mom was discovered, waited for his sister's words.
Jinwoo had decided to play dumb no matter what she said.
"Never mind...nothing..."
It seemed Sohee thought she wouldn't get a straight answer from Jinwoo, so she trailed off vaguely.
"Anyway, I really didn't expect mom to buy me these clothes, hehe."
Sohee, opening the shopping bag, pulled out the clothes and giggled like a child, delighted.
"Right? That's great, Sohee."
Seeing her like this, Jinwoo felt a warm feeling too.
Sohee held the clothes out, pondering for a moment before she spoke.
"Jinwoo, did you know there's a cinema and an amusement park here?"
"Yeah, I think I've heard about it."
"Keep your day free tomorrow, okay?"
Sohee asked somewhat shyly.
"Tomorrow?"
"Yeah, I have to come back here tomorrow to return the clothes Aunt bought me."
Listening to Sohee, it seemed she planned to return a see-through mesh t-shirt that their aunt had bought, which had already been a subject of dispute with mom.
She had already gotten permission from their aunt to return it after getting scolded that day, and had been making a poor show of it to secretly gather some allowance money without mom knowing. But then mom offered to give back the allowance, so she had postponed the return...
That's what she had decided to return tomorrow.
Sohee casually mentioned using the refund money to show Jinwoo around the department store.
Thus, Jinwoo and Sohee made a date for the next day with the goal of returning the item.
* * *
After spending some more time at the café, Jinwoo's mom and Minji returned.
It was time to eat, so Jinwoo's family headed to the food court in the basement.
On the way to the food court, they passed a pet store.
Inside the cage, puppies were squirming about, and Minji, spotting them from a distance, dashed over to start watching.
"They're so cute~ Hehe, it would be nice if we had a puppy at home too," she murmured dreamily while watching the puppies.
Mom looked at Minji with a troubled expression.
The family decided to go inside the store just to look around.
The large store had everything related to dogs: food, treats, grooming supplies, and even clothes and accessories for puppies.
Jinwoo's attention was caught by one particular display.
It was a display of dog collars.
The medium-sized collars hanging there reminded Jinwoo of adult toys.
Jinwoo thought that using such items on a person, bought from a real pet store and not an adult shop, would no longer be just playful but would actually treat them like a real animal.
Among those items, one particularly caught Jinwoo's eye.
A red leather collar with a bell.
Jinwoo imagined his mom wearing that red leather dog collar with a bell.
Just the thought seemed to send a surge of lustful pleasure through Jinwoo, nearly paralyzing his reason.
