EP.71 Discovery – 1 

‘Ah, I’m tired.’ 

When I got home from the hotel, that was the only thought in my head. 

If we’d come home together in the morning, it might have looked suspicious, 

so Mom went in first and I waited a while before coming back. 

As soon as I stepped inside, a wave of exhaustion hit me, 

but I didn’t regret it after such a satisfying night. 

‘No doubt Mom’s collapsed in her room... I’ll just sleep a bit more in mine.’ 

But just as I was taking off my shoes to enter the house, 

I sensed someone in the living room. 

My tired body didn’t think much of it. 

‘It’s probably just big sis.’ 

I never even considered that anyone might have found out about my secret night with Mom. 

If anything, since we’d come home at different times, 

I thought we’d avoided suspicion. 

“Daehyun. Can you come here for a second?” 

“Now? I’m a bit tired, can we talk later?” 

My sister’s voice was a little different than usual. 

It was gentle, but there was something intentional about it. 

“If you’re tired, you can just lie on my lap and listen.” 

Something about the atmosphere was off. 

I was too tired to say I wanted to go upstairs. 

There was a faint sense of foreboding, 

but her usual gentle tone led me to the sofa. 

“What’s up?” 

“Since you said you’re tired, lie down first.” 

As soon as I sat next to her, she wrapped her arm around me, 

and I naturally lay my head on her lap. 

‘Why did she call me?’ 

Maybe it was the fatigue, but my mind wasn’t working right. 

But her hand stroking my head was so gentle it chased away my worries. 

“Why did you call me, sis?” 

“You went out yesterday, didn’t you... When did you leave?” 

Suddenly, the drowsiness from her gentle touch vanished. 

My mind spun, wondering if I should get up, 

but I knew that would only make her more suspicious... ‘She’s come into my room before, so maybe she checked while I was gone?’ 

For now, I had to play it cool. 

I wasn’t sure she’d caught me yet. 

“Well... I just went out for a bit. Nearby.” 

“Hmmm... really? You know you can be honest with me...” 

Suddenly her touch felt subtly different. 

It was still gentle, but there was a hint of something sensual. 

But her soothing touch was so pleasant I didn’t want to move. 

“You went out with Mom yesterday, didn’t you?” 

“Uh...” 

A question I hadn’t expected at all. 

I flinched before I could help it. 

‘Did she catch me?’ 

Even as my mind whirled, her hand kept stroking my head gently, 

so I couldn’t bring myself to say anything. 

While I hesitated, Chaerin spoke first. 

“I heard everything... the sounds from Mom’s room last night...” 

Well. That’s it. 

At this point, I was definitely caught. 

And since we hadn’t even cleaned up the evidence, 

there was no point in denying it. 

But even so, I couldn’t bring myself to speak easily. 

“You really don’t have to worry so much.” 

She gently stroked my head, 

as if to say she’d accept anything. 

Looking up from her lap, I saw a motherly smile on her face. 

“It’s okay?” 

“I was a little surprised... but you’ve done this with me too, right?” 

Her hand, which had been stroking my head, slowly moved lower, 

creating a subtly sensual mood. 

Her touch was so sensual I could feel blood rushing to my cock. 

“That’s... true.” 

“I actually think it’s for the best. You must have been stressed, sneaking around until now.” 

Before I knew it, her hand was on my crotch, 

slowly rubbing my cock through my pants. 

“So you don’t have to hide anything from me...♥” 

Her voice was sweet, almost seductive. 

Just hearing it, filled with both affection and desire, made my cock harden. 

The way she stroked me soothed my tired body 

and made me feel like she was cheering me on. 

‘Big sis might be just as dangerously lewd as Mom...’ 

It was an unexpected discovery. 

That she could accept me having sex with Mom. 

The more she gently stroked my cock, the more my tension faded. 

Desire slowly filled the empty space, 

and I found myself wanting to just enjoy her touch. 

“If that’s how you feel, I won’t hide it anymore.” 

“Then can I ask one more thing?” 

“Anything.” 

“Did you do it with Chaehee too?” 

Her question was sharp. 

It was only natural to wonder if I’d touched other family members after being with her and Mom. 

But this time, I didn’t flinch. 

It felt like she’d accept even her brother sleeping with their mother, 

and she proved it by continuing to fondle my cock. 

“Actually... I did it with Chaehee noona too.” 

“Thank you for being honest...♥” 

Even after I admitted to sleeping with other family members, 

her face was filled with joy. 

She seemed genuinely happy that I’d told her everything. 

“Then should we just tell Mom everything?” 

Her hand moved up a bit, 

and she slipped it inside my pants. 

“All of it?” 

Her hand slid quickly into my underwear. 

But she didn’t stop there, massaging my cock as if giving a massage. 

“That way we wouldn’t have to sneak around anymore, and could enjoy it more.” 

She wasn’t wrong. 

It was just surprising to hear that from a sister who’d been so innocent just a few days ago. 

It was easy to see why. 

Her hand massaging my cock was filled with both motherly affection and sexual desire, 

and her breathing was growing heavier, as if telling me what she wanted. 

“Then if I tell Mom, will you help me a bit?” 

“I’ll help with anything you want...♥” 

Hearing her loving answer, 

my mind was filled with thoughts of how to confess my relationship with her to Mom. 

Mom was already like a tamed pet or slave, 

and I was sure she’d accept anything, though in a slightly different way than my sister. 

Once I’d come to that simple conclusion, 

the next thing on my mind was the bulge in my pants. 

“I’ll tell Mom later how I’ll do it. But before that...” 

Thanks to her enthusiastic fondling, my cock was already fully erect. 

No matter how tired I was, there was no way I could sleep like this. 

“I don’t think I can sleep like this with you stroking my cock... Can you help me out a little?” 

“It’s because of you, sis...” 

Her touch grew even more sensual, 

as if asking me to pour all my desire into her. 

She stroked me lovingly, and my cock throbbed at her affectionate caress. 

“I’ll take responsibility...♥” 

Her smile was both teasing and seductive, 

and looking up at her, I felt my desire surge. 

She pulled my pants down just like when I was a kid, 

and when she pulled off my underwear, my huge, erect cock sprang free. 

“Hehe... it’s gotten so big...” 

She sounded delighted as she looked at my hard cock. 

Looking up at her, I noticed something else that caught my eye. 

Her breasts, full of gentle affection. 

Just looking up at them made me swallow unconsciously. 

Especially lying on her lap and looking up, it felt even more intense than usual. 

“Sis.” 

I already knew what I wanted to ask for. 

My mind was full of the urge to suck her breasts. 

But before I could even ask, she seemed to sense it, giving me a kind but slightly lewd smile. 

“Ah...! Do you want to suck my breasts while I stroke your cock...?” 

She looked down at my cock and my face, 

her anticipation and excitement obvious. 

It was almost as if she was the one asking, not me. 

“Please, sis.” 

She wore an ecstatic expression as if she was feeling pure joy, 

and tossed off her bra. 

With her bra gone, her nipples showed through her top, making my urge to suck them even stronger. 

Even though Mom was upstairs, exhausted from sex all night, 

that only seemed to make me even more aroused.
