Chapter 51
As soon as Si-woo and Se-hee Noona stepped off the Ferris wheel, they headed straight for a nearby restroom.
"You remember what I said, right? Stuff the stockings deep into the bin so they can't be seen!!"
Se-hee Noona, who had been walking with Si-woo’s arm wrapped around her shoulders, spoke to him as they arrived in front of the restrooms.
Fortunately, the restroom they found seemed quiet enough to use without waiting in line.
Se-hee Noona was shivering slightly, rubbing her arms as if she felt the chill.
It was only natural. The weather was still deceptively cold, yet she’d had to tie her cardigan around her waist due to her "personal circumstances." Furthermore, both her upper and lower pieces of underwear had been removed under the pretext of helping Si-woo masturbate.
The only thing Se-hee Noona was wearing now was a form-fitting pink dress that accentuated her curves while leaving a significant amount of skin exposed.
Her outfit, which excessively revealed her slender thighs and supple breasts, was more than enough to draw the undivided attention of the many people visiting the department store.
Moreover, with her nipples poking prominently through the fabric of her dress with no way to hide them, even Se-hee Noona—who usually secretly enjoyed the gaze of others—seemed a bit uncomfortable now.
Even though they had wiped her down roughly with the pantyhose, there was no way he could let her put back on underwear that had been practically soaked in his semen.
Si-woo looked at Se-hee Noona and felt a wave of pity, compassion, and love.
—Especially the part about her walking around with no bra and no panties just for him.
"It’ll take a while to wipe everything down and get organized, so you should wait inside the ladies' room, okay?"
Si-woo placed his hands on Se-hee Noona’s exposed arms and rubbed them up and down a few times to generate heat, then gave her head a couple of gentle pats before hurrying into the men's room.
He grabbed several paper towels, dampened them with water, and entered an empty stall.
Opening the shopping bag, he first pulled out the pantyhose.
A lewd scent, a mix of semen and pussy fluid, wafted up and tickled the tip of Si-woo’s nose.
Si-woo reflected on the events that had just occurred—things no one would believe even if he told them.
Si-woo and Se-hee Noona had clearly been aroused by each other, and Si-woo had masturbated for the first time right in front of her eyes.
—And in a place that was practically outdoors, inside a Ferris wheel at a department store rooftop amusement park, no less.
To help Si-woo ejaculate, Se-hee Noona had intentionally poured lewd words and moans into his ear like a whisper. Thanks to that, Si-woo had been able to squeeze and fondle her breasts and buttocks, eventually even showing her the moment he ejaculated while holding her close.
—Though there was a bit of bickering involved.
Se-hee Noona’s friends—who might have been the ones to suggest the "Sex Diet" she and Shin-bi Noona were planning—had even said things that seemed to urge Si-woo to have sex with them, and she had even asked if Si-woo was interested in Shin-bi Noona.
Furthermore, the two of them had spoken quite freely about the sexual contact between Si-woo and Mom on the subway yesterday.
Perhaps Se-hee Noona was the type of person who had no boundaries when it came to these kinds of lewd fantasies.
Her lewd dialogue, which seemed to operate on the premise that sexual relations between family members or orgies with friends were acceptable, was certainly far removed from conventional common sense.
It was impossible to know what kind of possibilities Se-hee Noona herself was leaving open regarding a sexual relationship with Si-woo.
What would happen if he told Se-hee Noona about the sex he and Mom had already had?
Si-woo felt his heart tighten again, swept away by an inexplicable ecstasy that felt drenched in sadistic excitement.
—Even more so than when he had Se-young bite his penis while she was sleeping and sent a photo of it to Mom.
Si-woo couldn't tell for sure right now whether the object of that sadism was Mom or Se-hee Noona.
—Or perhaps it was himself.
As the only male in the household, Se-hee Noona often showed a sense of rivalry toward Mom, as if they were female competitors for his attention.
Although Se-hee Noona had laughed it off as a joke during lunch, she seemed quite bothered by the fact that Si-woo had gone out of his way to buy a gift for Se-young during their date.
Her huffy, annoyed reaction inside the Ferris wheel—when she pushed aside Se-young’s pajamas and used her own bra to clean up after Si-woo ejaculated—could be seen as an extension of that irritation.
—Even while her body rejoiced at being the object of her younger brother's lust.
The presence of the opposite sex within a family seemed to stimulate innate desires and instincts, fueling competition between members of the same sex.
Therefore, Se-hee Noona’s reaction to Si-woo’s actions couldn't be defined simply as romantic jealousy.
However, it was undoubtedly an instinctive biological response—a desire to be recognized by Si-woo through the lens of sexual attraction.

After using the wet paper towels to wipe down Se-hee Noona’s panties and bra, which were soaked with pussy fluid and semen, Si-woo hesitated for a moment. Then, he pulled out his smartphone and sent the photo he had taken of Se-hee Noona with her legs crossed inside the Ferris wheel to Mom.
If Mom compared the prominent nipples in this photo to the one taken this morning, she would surely realize that Se-hee Noona’s bra had been removed.
The number '1' next to the photo disappeared, and a reply from Mom came almost immediately.
'??'
Two question marks from Mom—it was unclear if she had noticed the chest area or not.
'I just took this inside the Ferris wheel.'
Si-woo wrote back to Mom, feeling as if he were showing off a girlfriend.
Mom took some time before replying, as if she were examining the photo of Se-hee Noona.
'She’s pretty~ But isn't Se-hee cold like that?'
Whether she was changing the subject or simply hadn't noticed, Mom only commented on Se-hee Noona’s outfit.
'I think she is a bit cold. She seemed to be shivering. It's still chilly out, after all.'
Si-woo tried his best to convey the situation to Mom exactly as it was.
'Then she should put her cardigan on. Why is it tied around her waist? Didn't you make her dress like that earlier, Si-woo?'
Mom sent a message, sounding worried about Se-hee Noona.
'There’s a bit of a stain on her dress... It got wet because she spilled a lot of water, so she tied it around her waist to hide it.'
Si-woo was subtly hinting at the truth while being as vague as possible about the physical affection and foreplay.
Si-woo felt a sense of superiority and a thrill in having this kind of conversation with Mom, who didn't know the exact progress of the sexual relationship between the siblings.
'Oh dear~ Then you should buy her something to change into! Se-hee’s going to catch a cold!!'
Mom was continuing the conversation with her son in the only way a mother could.
'Can I? Then can you lend me some more money?'
Si-woo made his demand, seizing the opportunity.
'Why borrow it? It’s for Se-hee, so I’ll just pay for it~'
Perhaps it was a resistance to alleviate her guilt, just like with Se-young, but Mom was sending a formal message as if trying to protect her daughter from her son.
'It’s because I’m the one who made her like that... I want to give it to Se-hee as a gift myself, okay?'
As if driving the final nail in, Si-woo wrote the message without using the title "Noona," just as he had done this morning.
Mom would surely know what that implied.
Even if Mom stopped replying, Si-woo didn't worry anymore.
He knew very well that Mom would eventually accept and comply with almost any sexual demand he made.
'I think Mom is still bigger than Se-hee.'
Following up on their previous conversation about how he’d know who was bigger as soon as he touched them, Si-woo prodded Mom, who had gone silent.
'What is?'
Mom replied instantly, as if she had been staring at the screen the whole time.
'Your breasts.'
Si-woo was indirectly informing Mom that he had touched Se-hee Noona’s breasts, watching to see how she would react.
He wanted Mom to give him some kind of reaction, whatever it might be.
Mom didn't reply for a long while.
Then, she suddenly sent a long message.
'Of course Mom is bigger! Se-hee is still an Advanced Academy student~ Why are you comparing things that are obvious just by looking? You really are a funny kid, Si-woo. You better pay back every cent I lent you later! I’m charging interest, son or not~'
Mom had snapped at Si-woo’s words, which stoked her competition as a woman against Se-hee Noona, showing a cute reaction that seemed to momentarily forget her maternal role.
