Jinwoo was chilling on the living room couch, watching TV.
Movie channel
On the TV screen, there was this regular Sunday morning show that introduced the latest movies.
Jinwoo had just turned it on, thinking about finding something decent to watch with his sister.
Stuff like monster movies with special effects or warm family flicks, and the latest cinema versions of famous animations were getting showcased one by one.
Neither Jinwoo nor his sister Sohee were really into movies, so as long as it was some popular flick to kill time, they didn't much care what they picked.
So, to put it exactly, Jinwoo was basically killing time in the living room, picking out a movie while waiting for his sister Sohee to come out of the changing room.
* * *
Sohee came out of the shower after a while.
She was wearing light green shorts that looked like a skirt she had seen earlier, and a thin, beige cotton T-shirt.
When Jinwoo glanced at Sohee coming out of the changing room, her face was slightly flushed.
Sohee had an expression that made it hard to tell if she was angry or not.
Jinwoo sneakily looked at Sohee, then pretended to focus back on the TV screen.
Sohee, apparently annoyed by Jinwoo, who seemed oblivious to the mess he had just made with her bra, marched up to him and smacked him on the head.
Thud!!
"Ouch!!"
As if expecting the hit, like following a scripted play, Jinwoo grabbed his head and let out a loud scream.
-In truth, it wasn't that painful, just a bit loud-
"You cherish that, you dummy~~!!"
Sohee said disapprovingly, looking at Jinwoo who looked as if surprised to be hit on the head.
It would be only natural considering Jinwoo had dirtied her bra with semen, but since Sohee had just showered, she wasn't wearing a bra.
Her huge breasts were tightly encased in a white T-shirt, stretching it to the point of bursting, with small, shy protrusions adorably sticking out on both sides.
Sohee was blushing, rolling her eyes around, unable to meet Jinwoo's gaze directly.

But on reflection, it seemed like Sohee was annoyed about something off-target.
It would have been more reasonable for her to be angry about Jinwoo having dirtied the underwear she was going to put on again after her shower.
-It wasn't just about tampering with her cherished underwear-
Maybe it was a disguised way of showing her protest against Jinwoo's new perverted acts.
It was as if Sohee was trying to share the secretive thrill of their sexual play, just like when Jinwoo had oddly confirmed whether she had been back from her early morning jog right before he went off to masturbate for the first time that day.
Although Sohee lightly hitting Jinwoo's head was clearly an expression of her discomfort and embarrassment, upon deeper thought, it wasn't really a rejection or refusal of Jinwoo's actions.
It seemed reasonable to interpret that Sohee was hinting she wouldn't really mind his behavior of soiling new underwear, as long as it wasn't her cherished ones.
Caught by Sohee's quirky remark and the dizzying visual of nipples protruding in front of her ample breasts, Jinwoo was once again excited, feeling his heart pound breathlessly.
* * *
"You can pick the movie when we get there, so stop watching TV and get ready to go out!"
Sohee said this to Jinwoo, who had been watching the movie channel, then turned around and went upstairs to her room.
The silhouette of Sohee's backside, overlaid with the flesh-colored silhouette he had seen through the bathroom glass door earlier, seemed to make her body appear even more seductive.
Jinwoo got up from the sofa and went into the changing room.
The dirty clothes and Sohee's bra that had been in the laundry basket were all in the washing machine now.
It must have been Sohee who moved them after checking post-shower.
Jinwoo felt an inexplicable sense of satisfaction and pride knowing that Sohee had personally moved the clothes and underwear he had just dirtied into the washing machine.
* * *
Jinwoo went up to his room to change and get ready to go out.
He put on a white long-sleeve shirt and over it a navy long-sleeve round-neck sweater. His pants were stretchy gray cotton trousers.
Just in case, he tucked a card that his mom had left behind into his pocket.
When he came downstairs, Sohee was already ready to go out and standing in the living room.
She was tightly wrapped in a pink dress with a deep neckline that they had bought at the department store yesterday.
She wore a deep pink cardigan over it, which was open at the front, following the curves at the edges of her chest.
-The cardigan didn't seem very effective at covering up-
Sohee's tan skin harmonized well with the colors of the cardigan and dress.
She was wearing beige sheer stockings that seemed to be pantyhose, as they went up inside the dress.
Jinwoo momentarily lost himself in admiring Sohee's elegant dress and demeanor.
"How do I look? Does this dress suit me?"
Noticing Jinwoo staring blankly at her, Sohee playfully twisted her body from side to side, proudly showing off the dress she had bought the day before.
"Yeah, Sohee, you look really beautiful."
Having ejaculated twice before, Jinwoo still felt a mix of excitement and thrill seeing Sohee, and was barely managing to control his arousal.
Looking closely, Sohee's nipples were not as visible through the dress as they had been yesterday.
"But you wore a bra today?"
Jinwoo asked casually, feeling a bit disappointed.
"Uh.. yeah, yesterday I just tried it on for a bit so I took it off to avoid showing the straps, but usually, I wear it like this!"
Sohee kindly explained, pinching the thin transparent straps of her bra between her thumb and index finger.
The conversation about Sohee's underwear, which would have been difficult under normal circumstances, seemed to have become a natural topic between Jinwoo and Sohee after Jinwoo's earlier masturbation session seen through the frosted glass door.
* * *
"Wait a sec, Sohee! Before we go out, let's take a few more pictures of you!"
Jinwoo called out to Sohee as she was about to leave the house, all set to go.
"Pictures? I'll be wearing this often, why?"
"Because you look so good right now~ It'd be a waste not to capture it! Plus, I need a photo for my smartphone background tomorrow..."
"Smartphone background? You took one earlier, didn't you?"
"That was just for today! I need to take one for tomorrow too!"
Jinwoo seemed a bit pushy as he spoke to his sister.
"Ah, really..."
Sohee gave a hollow laugh but didn't seem to mind her brother's request too much. After thinking for a moment, she struck a model-like pose in front of Jinwoo.
Click!
Click!!
Click!!!
Jinwoo started taking photos of his sister with his smartphone.
After a while, Sohee leaned forward slightly, pushing her cleavage together in a provocative pose.
The purple bra and some skin below the sternum were visible between her dress and her cleavage.
Jinwoo zoomed in on Sohee's chest area and secretly took a few photos without her noticing.
"How is it? Did they come out well?"
After taking enough photos, Jinwoo thought he'd just hide the chest pictures, but Sohee suddenly came over and took his smartphone.
"Just a sec, Sohee..."
Jinwoo was flustered and couldn't actively stop his sister as she took his phone.
Sohee flipped through the photos on Jinwoo's smartphone and, finding the zoomed-in chest photos, chuckled as if she had expected it.
She picked a full-body photo of herself in the pose showing her cleavage and showed it to Jinwoo.
"Make this one your background for tomorrow, got it?"
Then she handed the smartphone back to Jinwoo and went to the entrance to put on her shoes.
Sohee's mocking reaction was a bit embarrassing and awkward for Jinwoo, treating him like a child in the palm of her hand.
However, Jinwoo also felt a strange touch of emotion because Sohee was earnestly responding to his pathetic perverted antics.
Jinwoo put on his shoes and followed Sohee out the door.
