EP.36 Eldest Sister – 1 

It had been a week since I spent two straight days having sex with Chaehee noona. 

During that time, I’d had secret trysts with Mom or Chaehee noona without the other sisters knowing, and just last night I’d spent a steamy time with Mom in my room until dawn. 

Because of that, I couldn’t help but wake up pretty late again today. 

“Come to think of it... today, both Mom and Chaea noona said they’d be busy with work, right?” 

Naturally, that meant the only ones left at home were me, Chaehee noona, and Chaerin noona. 

Chaerin noona had a bit of an innocent side, so it would be easy enough to secretly have sex with Chaehee noona without her noticing. 

‘If it comes to it, we could always go out to a motel.’ 

As I was indulging in such lustful thoughts as soon as I woke up, someone came in through the open door. 

“Ah... looks like you finally woke up.” 

“What’s up, Chaerin noona?” 

The person who entered was Chaerin noona. 

Her hair had a brownish tint and flowed down to her back, giving off a very feminine vibe. 

On top of that, her figure was in no way inferior to the other sisters or Mom. 

The white tank top with string straps showed off a chest full of maternal charm. 

“I thought you’d be up by now, so I came to check. Aren’t you hungry?” 

Chaerin noona was a beauty who seemed both innocent and gentle. 

Her voice, as always, was filled with gentle consideration, and just hearing it made me feel a little better. 

She gave the impression of someone who would accept whatever you did. Of course, that didn’t mean she’d just go along with siblings having sex as if it were nothing. 

“I made breakfast, so come down and eat.” 

“What about Chaehee noona?” 

“Chaehee said she was going out to hang out with a friend in the city. Why? Did you have something to do with her?” 

“No... I was just curious.” 

That meant, in other words, the only one home right now was Chaerin noona. 

It was a little disappointing that I couldn’t sneak off to have sex with Chaehee noona, but before I knew it, my lust was shifting toward Chaerin noona. 

Having already embraced Chaehee noona and Mom, my instincts now wanted Chaerin noona too. 

‘The important thing is how to go about it.’ 

In a way, Chaerin noona was the easiest target. She was the most innocent and gentle of the sisters. 

When she said she was going to major in early childhood education, the whole family immediately understood. 

‘Maybe I’ll try subtly making physical contact.’ 

Winning over Chaerin noona might be surprisingly simple. 

I was sure she wouldn’t get angry even if I suddenly got touchy-feely. 

Thinking that made my desire grow even stronger. 

The act of corrupting an innocent, gentle sister with pleasure-just imagining it made my lust surge. 

“Noona, did you eat yet?” 

“I was waiting to eat with you, so I haven’t eaten yet.” 

“Really? Then let’s go down together.” 

As soon as I jumped out of bed, I approached her. 

Up to this point, it was no different from usual, but as I left the room, I put my arm around her body from the side. 

“...?” 

As expected... noona just looked a little puzzled. Since we’d always lived as siblings, she had no suspicion at all. 

For me, this was the perfect opportunity. 

“It feels like I haven’t been this close to you in a while, noona.” 

“Heh... are you feeling clingy today?” 

Her reaction was like that of an older sister looking at her cute little brother. She smiled gently and didn’t show any wariness about the physical contact. 

“Well... ever since I was a kid, whenever Chaehee noona teased me, I’d often cling to you, right?” 

“That’s true. You were cute back then.” 

“Are you saying I’m not cute now?” 

“I mean you’ve grown up a bit. But seeing you still like clinging to your noona, you’re still a kid at heart.” 

Despite the sudden skinship, noona actually seemed happy. 

‘Maybe I can go even further?’ 

I slowly moved the hand around her waist upward. Her defenseless body was like a delicious prey. 

While moving cautiously, we reached the stairs to the first floor, and as we went down, I managed to rest my hand on her chest. 

“Hnn...” 

My hand touched her chest. The thin tank top was no obstacle at all. 

If she’d been walking around in just her underwear like Chaehee noona, there wouldn’t have been any problem. 

But a tank top without a bra underneath offered almost zero protection. 

“By the way, what did you cook, noona?” 

“Just simple curry...” 

I spoke nonchalantly as I subtly moved my hand, making it seem like it was just an accidental touch, not intentional groping. 

Maybe she felt a bit weird about it, but she didn’t do anything, acting like it was nothing. 

‘If things go well, I might be able to seduce the eldest sister today...’ 

Desire and anticipation mixed, making me feel excited, and my mind was already full of fantasies about embracing Chaerin noona. 

“Hnn...! Haa...” 

Daehyun was subtly teasing Chaerin’s nipples. 

Each time he brushed her nipples as if by accident, Chaerin felt a strange new emotion and pleasure for the first time. 

‘Every time Daehyun’s hand brushes me while we walk... it feels weird...’ 

Her previously steady breathing had become rough. 

At first, she didn’t think much of it, but now, every time her nipples were stimulated, she felt better and better. 

‘He’s just my little brother next to me... so why is my heart pounding like this...’ 

She thought it was just a coincidence that her nipples were being touched, but her heart was beating faster and faster. 

The more she felt instinctive pleasure as a female, the more she became aware of the male by her side. 

Especially, she was unconsciously fixated on the fact that the one stimulating her nipples was a male. 

“Noona, are you feeling sick? Your face looks a bit red.” 

“N-no...! It’s just a little hot...!” 

Even after coming down to the first floor, Daehyun’s teasing continued. But Chaerin couldn’t say anything about it. 

Her nipples had become erect from the constant stimulation. 

‘Every time his hand touches me... I feel it...’ 

If she said anything, he might realize her nipples were hard. 

That thought kept her from speaking up. 

Daehyun already knew, but acted nonchalant, so Chaerin thought he didn’t notice. 

That made it even harder for her to say anything. 

“Haa... haa...!” 

She’d never even properly masturbated before, but now, a lewd desire had taken root in her heart. 

She wanted Daehyun to keep stimulating her nipples like this. 

‘J-just a little more... hnn...!’ 

Without realizing it, her steps slowed as she focused on Daehyun’s hand teasing her nipples. 

But eventually they reached the dining table, and Daehyun let her go surprisingly easily. 

“I’ll wait here, noona.” 

“Okay... I’ll heat it up right away...” 

When Daehyun let go, Chaerin felt disappointed. She missed the pleasant stimulation. 

She tried to suppress her feelings as she moved to heat up the curry, but it was obvious she wanted more. 

‘He let go, but... my nipples are still hard...’ 

Chaerin’s nipples were poking through the white tank top. 

Even when she dressed lightly, they’d sometimes show, but never like this. 

More than anything, Daehyun was the only man in the house at the time, and she’d always thought of him as her cute little brother. 

But now it was different. 

Her nipples were much harder than usual, and she could feel it herself. 

Unconsciously, she was starting to see Daehyun as a man. 

‘For some reason... Daehyun seems more manly now...’ 

She glanced at Daehyun, and a jumble of emotions confused her mind. 

Her body, especially her lower abdomen, felt a faint heat, like it wanted something. 

“Noona.” 

“Huh...?!” 

Chaerin didn’t know why she answered in such a startled voice, but she felt one thing for sure. 

Daehyun’s voice when he called her had changed somehow. 

Chaerin had no experience with men, but she could sense it instinctively. 

The moment she heard Daehyun call her name, she felt a strange happiness well up. 

“Should I give you a massage after we eat?” 

“A massage...?” 

“You don’t look like you’re feeling well, and it’s been a while since we spent time together. I thought it’d be nice.” 

There was no thought of refusing in Chaerin’s mind. 

Her head thought it was just a normal suggestion from her brother, 

but her instincts felt like she was being pleasantly tempted. 

“O-okay...” 

For the first time, Chaerin felt excited by a man, and a strange sensation in her lower belly.
