EP.52 The Eldest Sister’s Change – 6 

“Uuungh...” 

When Chaerin opened her eyes, 

the first thing she saw was her own room, already bright with daylight. 

‘I’m sure last night...’ 

As she recalled what happened with Daehyun the night before, 

she felt her face flush hot. 

But there was no negative emotion at all. 

Rather, it felt as if something that had been stuck inside her was pleasantly resolved. 

‘Being touched by Daehyun... and then...’ 

It was no longer possible to rationalize it as just a normal massage. 

Her most intimate place had been thoroughly teased, and even her brother’s cock had been inside her. 

She’d known it before, but had tried to ignore it. 

And last night felt even better than the previous time, 

so the memory of pleasure was deeply engraved in her body and mind. 

‘It... it felt good...’ 

Chaerin smiled happily without realizing it. 

Before, she’d just been swept away by pleasure, not knowing what to do, 

but last night, she felt like she was truly enjoying it together with her brother. 

Especially when her brother kissed her most private place, 

her heart felt like it would burst with joy. 

‘And I didn’t refuse when he asked to hold me...’ 

At that moment, there was only one thought in her mind. 

She wanted her brother’s thing. 

She couldn’t suppress that impulsive longing. 

In the end, she’d worried she might be rejected as she asked, 

but she got what she wanted. 

‘I want to feel it again...’ 

Maybe she could go back to how things were as if nothing happened, 

but it was impossible to forget the feelings and pleasure she’d experienced last night. 

Chaerin instinctively knew she’d end up seeking Daehyun again, just like last night. 

“Hnnng...” 

Even though she’d only just woken up, 

remembering what happened last night made her feel like the afterglow still lingered in her body. 

And before she knew it, the panties she was wearing were already soaked. 

Daehyun must have at least dressed her in underwear and laid her on the bed, 

but inside Chaerin’s pussy, his semen still remained. 

‘My panties are wet... it feels weird...’ 

Chaerin’s panties were gray, 

and were stained dark with the semen and her own juices that had leaked out. 

‘The smell... I weirdly want to keep smelling it...’ 

Her wet panties spread a decadent scent around her. 

Every time the faint but lewd smell tickled her nose, 

Chaerin felt the memories of last night come alive again. 

Instinctively, she slipped her hand into her panties 

and felt her own soaked pussy flesh. 

“Hnnng... haat...!” 

The more she touched herself inside her panties, 

the more her ragged breathing echoed through the room. 

She looked like a girl masturbating for the first time, knowing nothing, 

but having already tasted her brother’s big cock, she wanted even greater stimulation. 

‘Daehyun’s... was so big... it felt so full when it was inside...’ 

The pleasure when her brother’s cock had penetrated her deeply- 

just remembering it made Chaerin’s face go slack with bliss. 

“Haaat... huu...! Uuungh...!” 

She hadn’t meant to masturbate, 

but before she knew it, she was touching her pussy with her fingers and letting out faint moans. 

After several minutes of self-pleasure, 

she suddenly remembered what her brother had whispered in her ear the night before. 

‘Noona, come to my room tomorrow if you want to do it.’ 

Her brother’s words, telling her to come to his room whenever she wanted. 

She didn’t even need to think about what that meant. 

They’d already had sex, 

so it obviously meant she could take his cock again, just like the night before. 

“Haa... ugh...!” 

Chaerin barely managed to stop masturbating, 

but that didn’t cool her aroused body. 

If anything, an excited anticipation was rising in her chest. 

‘If I go to Daehyun’s room now...’ 

As if possessed, Chaerin got out of bed. 

Her reflection in the mirror showed her wearing only a bra and panties, 

and even the panties were so wet anyone could tell at a glance. 

‘I should at least change my panties...’ 

She grabbed her panties and slowly pulled them down. 

Inside, they were even more soaked than she’d expected. 

Her pussy flesh, moist and vividly pink, looked like she was in heat. 

Gravity had made the semen and juices run down between her legs, 

and she knew that even if she changed panties, they’d just get wet again soon. 

‘He came so much inside me... it’s running down... but it feels weirdly good...’ 

It was an obscene, filthy sight, 

but her face in the mirror looked like it was overflowing with happiness. 

Her mind was already filled with the thought of wanting to be penetrated by her brother’s cock again. 

Taking her brother’s cock and being filled with his semen- 

for Chaerin, it was simply an act that brought her happiness. 

‘The smell... seems even stronger now...’ 

Instinctively, Chaerin looked at the panties in her hand. 

Stained with both her brother’s and her own juices, they felt like proof of their lovemaking. 

She brought the panties to her nose, 

and the thick scent of male and female mixed together filled her mind. 

“Hnnng... haat...” 

Before she knew it, more juices were leaking from her pussy, 

and little puddles were forming on the floor. 

But Chaerin didn’t even think of cleaning up the floor. 

Her mind was filled only with the thought that she needed to go to Daehyun’s room. 

‘There’s no point in changing, I’ll just get wet again anyway.’ 

Her choice was to put the already-soaked panties back on. 

She thought it was fine since Daehyun had already seen everything, 

but she was still wary of her other siblings or her mother. 

In the end, she put the panties she’d been holding back on, 

and the damp, strangely pleasant sensation pressed against her pussy. 

“Ugh... t-this feels... almost like...” 

It looked as if she’d taken them off just to smell them, then put them back on. 

She was alone in her room, 

but if anyone else had been there, they’d have called her lewd and she would have had nothing to say. 

But what Chaerin felt was a guilty thrill and a tingling excitement. 

“Hnnng...! Haat... haa...” 

Wearing panties soaked with her brother’s semen, pressed against her pussy- 

the more she thought about it, the more her juices kept flowing. 

Her legs were already heading for the door, 

and when she stepped out into the second-floor hallway, the air felt pleasantly cool on her skin. 

The lust boiling inside her, wanting to mix bodies with her brother. 

The quiet house, as if telling her she was alone with Daehyun. 

The thrill of walking around in just her underwear, unlike usual. 

All of it seemed to be pushing her toward Daehyun’s room. 

Especially the wet panties clinging to her pussy told her just how much she wanted her brother. 

‘I want Daehyun to hold me again...’ 

Finally, Chaerin arrived at Daehyun’s door, 

carefully opened it, and stepped inside. 

Creak- 

There was barely any sign of life in the room. 

But when Chaerin looked at the bed, she saw Daehyun lying there asleep. 

It was already well after sunrise, 

but Daehyun didn’t even notice someone had entered his room. 

Of course, it was only natural. 

He’d spent all day yesterday having sex with their mother, Chaeyeon, 

and then continued for a long time through the night with his eldest sister, Chaerin. 

But something caught Chaerin’s eye. 

“Ugh...” 

It was obvious to anyone that his cock was hard, 

the bulge in his pants clearly showing his arousal. 

Seeing her brother’s erection as he slept, 

Chaerin felt lust and affection swirl together inside her. 

His erect form looked adorable to her, 

and she wanted to take care of him as a sister. 

‘Yesterday, Daehyun did everything for me...’ 

Just a moment ago, Chaerin had come thinking about being taken by her brother, 

but now she wanted to make him happy with her body. 

Sss- 

With a loving gaze, Chaerin approached the bed, 

then quietly climbed up onto it. 

“Daehyun... are you asleep...?” 

She asked softly, 

but all she got in return was the sound of deep, peaceful breathing. 

After confirming Daehyun was asleep, 

Chaerin carefully pulled down his pants and underwear. 

His erect cock sprang up proudly. 

“Ah...♥” 

Finally, her brother’s cock, standing tall toward the ceiling, was revealed. 

Chaerin gazed at it with eyes full of anticipation and affection. 

But Daehyun was still asleep, 

and Chaerin felt a strange, thrilling excitement, as if she were playing a forbidden game.
