EP.86 The Secret Only My Sister Doesn’t Know – 5 

“Mmm...” 

When Chaehee woke up, she realized she was lying on the bed. 

The intense sex with Daehyun the night before hadn’t ended with just one round; 

until late into the night, she’d been pinned down, squeezing her pussy around him. 

“Ugh... did I really sleep this late...?” 

Strong sunlight poured in through the window. 

Even without checking the time, she knew it was well past morning. 

Chaehee was still groggy with sleep and recalled what had happened the night before. 

‘Getting fucked like that... felt really good...’ 

The pleasure of a strong cock pushing in from behind. 

Just remembering it made her body react on its own. 

It felt like the lingering heat was driving away her drowsiness, wrapping around her body. 

Just thinking of her brother’s cock made her pussy twitch and clench. 

“Haa... huu...! There’s still... inside...” 

She’d taken her brother’s cum multiple times the night before, 

and her pussy was still filled with semen. 

It was proof of just how hard Daehyun had fucked her last night. 

‘It’s so wet... the feeling...’ 

Before leaving the room, Daehyun had dressed her in underwear, 

but her panties were soaked with his cum. 

The panties held back some of the leaking semen, 

but there was so much that they couldn’t contain it all. 

Because of that, the bed was soaked and reeked of sex. 

“Ugh...” 

When she lifted the blanket Daehyun had covered her with, 

she saw a huge stain of his cum and her own juices. 

The bed was as wet as if she’d wet herself, 

and she couldn’t deny that she’d moaned and begged her brother for more. 

“Ugh... I told him to take it easy...” 

She’d asked him to stop partway through, 

but Daehyun wasn’t the type to listen to that. 

So the bed was still damp even now. 

But she didn’t feel bad about it. 

If anything, she felt a strange happiness that Daehyun had wanted her body that much. 

‘I even made that weird promise...’ 

The promise to have sex in secret from the rest of the family. 

It was a much riskier thing than usual. 

But Chaehee couldn’t refuse. 

Every time her brother’s cock invaded her belly like it was conquering her, 

she was filled with the desire to accept it. 

‘He probably didn’t just mean doing it in secret in the room...’ 

They’d even made a bet about it, 

so it wouldn’t be like locking the door and sneaking around as before. 

She knew from experience that she’d be taken in an even riskier situation. 

“Ugh...! Haa...” 

Just imagining being fucked by Daehyun while the other family members were around 

made her pussy walls tremble. 

It had all started with her own lewd teasing, 

but now Daehyun was the one in control. 

Chaehee deliberately tried not to think about it, 

but her body instinctively felt pleasure in submitting to Daehyun. 

“Ugh...! F-first, I need to wash up...” 

Even now, semen was oozing slowly from her pussy. 

With other family members in the house, she had to clean up first. 

She couldn’t just walk around reeking of being fucked by her brother. 

Sss- 

She covered the traces from last night with the blanket, 

grabbed a clean pair of underwear, and headed for the bathroom on the first floor. 

‘It feels... a little different from usual...’ 

Normally, walking around the house in just underwear was nothing, 

but walking around in panties soaked with cum was different. 

Especially with her pussy full of semen that could run down her thighs at any moment. 

“Ugh... huu... haa...” 

That lewd tension made her heart race in a strange way. 

She might get caught by the other family members. 

The more she thought about it, the more aroused she became. 

‘It’s because of what we talked about yesterday... I can’t stop thinking about it...’ 

She was so conscious of it because of the promise she’d made with Daehyun. 

If not for that, she would have just worried about not getting caught. 

Once the thought took hold, it grew and grew, 

until it was impossible to stop. 

Tap- 

“Are you up, Chaehee?” 

“Ah...!” 

As soon as she reached the first floor, 

Chaehee was startled by Chaeyeon’s voice. 

“Yeah...! I-I’m up...!” 

She tried to answer as calmly as possible, 

but her voice was tinged with embarrassment. 

“Don’t sleep in so late.” 

“Huu... s-sorry...” 

Chaehee answered and quickly hurried to the bathroom. 

But inside, she felt a thrill at almost being caught. 

That tingling excitement seemed to poke at her pussy, 

and every step she took, cum leaked from her panties. 

The mixture of semen and her own juices ran down her thighs, 

but until she was out of her mom’s sight, she couldn’t even close her legs. 

“Huu... haa... huu...!” 

By the time she reached the bathroom, 

her breathing was rough from her aroused body. 

‘My body’s... so hot...’ 

On instinct, Chaehee slipped her hand into her panties. 

As expected, the inside was sticky with Daehyun’s cum, 

and when she gently rubbed her slick pussy, a sweet moan escaped. 

“Haa...!” 

For a moment, she wanted to masturbate right there, 

but she barely managed to resist and went into the bathroom. 

‘Maybe I’ll feel better after I wash...’ 

When she pulled down her panties, 

cum stretched in a long string like a plug being removed. 

“Ugh...!” 

It dripped down between her legs and onto the bathroom floor, 

and she could see just how much she’d taken inside. 

‘S-so much...♥’ 

Her brother had filled her up with cum, 

and that happiness made her pussy burn even hotter. 

She turned on the shower and sprayed herself, 

but the heat inside her wouldn’t go away. 

Ssshhh- 

“Ugh...! Haa... I need to get it out from inside...” 

Her slender fingers reached for her pussy, 

slipping inside and slowly rubbing her walls. 

“Hngh...!! Haa... huu...!” 

Each time she rubbed her cum-filled walls, 

her pussy twitched and more cum leaked out. 

Anyone watching would have thought she was masturbating. 

“Haa... it keeps coming out...! Hngh...!!” 

The more she scraped out the cum, 

the more her pussy clenched around her fingers and she let out sensual moans. 

Thankfully, the sound of the shower masked her moans, 

and she kept fingering herself until only her own juices were left. 

“Haa... huu... n-now... again...” 

Lost in pleasure, a thought rose in her mind: 

that she could take her brother’s cum again. 

It was a fleeting, irrational thought, 

but her desire to be filled again was real. 

Especially as her pussy clenched around her fingers, 

she longed for her brother’s thicker cock. 

‘Now that I’m clean... I’ll go back to my room...’ 

After a quick shower, she turned off the water, dried herself, and put on new underwear. 

‘Ugh... it’ll probably get wet again soon...’ 

This time, it wasn’t cum soaking her panties, 

but her own juices, slowly leaking out. 

“Back to my room first...” 

Creeeak- 

As she opened the bathroom door and stepped out, 

she ran into someone right in front of her. 

“Did you just finish washing, sis?” 

Waiting for her outside the bathroom was Daehyun. 

Suddenly seeing him there, Chaehee felt flustered, 

but at the same time, a strange anticipation bubbled up inside her. 

“Yeah...” 

“Then you have to keep your promise from yesterday.” 

“Ugh... are you really going to do it...?” 

“Of course. You’re not saying you can’t keep your promise now, are you, sis?” 

“Ugh...!” 

Refusing was impossible. 

Her body was already looking forward to being taken by her brother. 

On top of that, she was still feeling the thrill of risky excitement from earlier. 

Sex in secret from her sister and mom. 

Just imagining the pleasure of it made her mouth move on its own. 

“D-do whatever you want...♥” 

She tried to sound curt, 

but what came out was a loving voice. 

Watching her, Daehyun smiled to himself. 

‘Sis has no idea.’ 

Chaehee was soaked in the thrill of being taken in secret by her brother, 

completely unaware she was walking into a trap. 

“Chaerin noona’s watching TV on the sofa, so let’s go there.” 

Daehyun patted her butt as if to tell her to go first, 

and Chaehee had no choice but to follow, her body burning with desire.
