Side Story 5) Siblings’ Tale 17

“Mmm… Dajun-ah. Do you want to shower too?”

It was a close call. The moment my sister came out of the bathroom, I hastily hid inside the wardrobe.

Even though I’d lost myself in the heat of the moment earlier, it seemed I’d retained at least some rationality. As soon as we heard the water turn off, Oppa and I quickly straightened our disheveled clothes and acted as if nothing had happened.

The place I hid was a wardrobe just big enough for one person. Whether it was fortunate or not, my sister had taken a bathrobe with her beforehand, and she spent a long time drying herself in the bathroom, which gave us enough time.

She came out, drying her hair with a hairdryer, and asked Oppa. He responded casually as usual before heading into the bathroom to shower. Thankfully, it seemed we hadn’t been caught.

“……”

Still, how long was I supposed to stay here? From what I could tell, I’d have to stay until the two of them wore themselves out from going at it…

I wanted to masturbate. I wanted to touch myself while smelling the condom I’d stuffed in my pocket. But in my hurry to hide, I’d taken off my uniform, leaving it at my feet. I couldn’t bend over to get the condom because of my chest.

Still, I could reach down and rub my pussy if I wanted.

‘No, no.’

If I masturbated, I’d definitely get caught. It’s not like I’m dry-if anything, I’m so wet it’s practically overflowing. And the sensitivity? Just a little touch would make me moan, and the squelching sounds would definitely be heard.

Of course, that didn’t stop me.

Just a little. Really, just a little… I mean it.

At least I had some material to work with, thanks to the facial I’d gotten earlier. If I closed my eyes and took a deep breath, I could faintly smell Oppa’s cum. Maybe I should’ve just kept it in my mouth. But even if I had, I would’ve probably drooled it out when he fucked me.

“…Huh?”

Just then, my sister, rolling around on the bed, touched something and made a strange face. Peeking through the wardrobe gap, I saw she was touching a slightly damp spot.

‘……!’

The bed was wet!

But I wasn’t too worried. Since I’d been riding Oppa earlier, there wasn’t an obvious wet patch, and I’d also left a water bottle nearby just in case.

Sure enough, my sister looked around, spotted the water bottle on the desk, and relaxed.

‘Phew…’

After carefully rubbing my pussy for about five minutes…

Oppa stepped out, wrapped in a towel.

“Dajun-ah, you’re out already?”

My sister’s giggly expression was pretty cute. Though not as cute as mine, of course.

“Yeah, didn’t take long, right?”

Oppa replied while running a hand through his wet hair. What followed was a disgustingly sweet couple moment. When he sat down and turned on the hairdryer, my sister pressed her chest against him and dried his hair for him. Even though hers was smaller than mine.

Objectively speaking, hers was still big, but there was no denying it was smaller than mine. Watching them, I carefully slid a finger inside.

“……”

No sound, right? Even if there was, the hairdryer would’ve drowned it out. Anyway, Oppa’s short hair dried quickly, and soon the two of them were on the bed. First, he climbed on top of her for a deep kiss-so intense it made my face burn just watching.

‘Wait, Oppa knows I’m here, and yet…’

Of course, this was the right move to avoid getting caught. But that didn’t stop me from feeling petty.

Oppa kissed my sister while groping her all over, then went straight for her trembling breasts. Given what we’d done earlier, she didn’t seem to need much foreplay. Maybe she was just as sensitive as me.

After playing with her chest, Oppa pulled back and slowly moved his hand downward. My sister twitched like something out of a cartoon.

I mean, I can blame genetics, but why is she like that?

Does that mean Oppa’s just that good?

…Maybe I’m actually normal, and Oppa’s just so skilled he makes me like this.

Of course, that couldn’t be it. Right now, my juices were dripping down my thighs.

Not just dripping-pouring. I shouldn’t be leaking this much just from fingering myself while hiding in a closet.

And I’m only using one finger, lightly teasing myself.

“Mmm…♡”

My sister moaned in pleasure, surrendering herself to Oppa. Even from my perspective, she looked like she was feeling amazing. At the same time, Oppa’s hand moved lower, and lewd squelching sounds filled the air. It seemed like he was about to go straight for penetration, as he quickly adjusted his position.

“I’m doing it.”

“Yes…♡”

Compared to when he did it with me, this was a much gentler, more loving kind of sex. No, what we did was more like mating-this was actual sex. The way they moved together looked so affectionate. Even though the sounds from my sister’s pussy were just as obscene as mine, from a third-person perspective, their lovemaking had a completely different vibe.

At least the lewd noises meant I could masturbate freely. Even when I slipped in a second finger and moved faster, the sounds of their sex drowned out mine. Even if they heard, they’d probably think it was their own.

“Ah, condom.”

After moving slowly for a while, he stopped to put on a condom. Meanwhile, when we did it, he just creampied me and made me take the morning-after pill.

…Maybe next time he creampies me, I won’t take the pill.

“Hngg…♡”

Once the condom was on, they started fucking again. The sounds from her pussy were unbelievably obscene, but the moans from above were more restrained. Anyone could tell Oppa was holding back.

“…Can you go a little harder?”

Unable to hold back, Oppa finally asked, and my sister nodded. Of course he wouldn’t be satisfied with tame sex after wrecking my pussy like that.

“Hngg♡ Ahh♡ D-Dajun-ah…♡ I-I can’t…♡”

Immediately, the sound of skin slapping filled the room as Oppa’s hips moved faster. Overwhelmed, my sister let out proper moans and came hard.

But they didn’t get to do it much longer. After cumming once, he put on another condom, and my sister spoke up.

“C-Can you go a little softer… ngh♡”

“Uh… okay.”

Oppa looked slightly dissatisfied but agreed and slowed down.

“……”

Seems like what we did earlier had more of an effect than I thought. Normally, gentle sex would’ve been enough for him. But now, after the intense stimulation I gave him, he didn’t seem satisfied at all.

“Ahh♡ Hah♡ Hngg…♡”

-Squelch squelch squelch squelch

Watching their tame lovemaking, I started warming up my pussy. It was just masturbation, but I held back from cumming.

Seeing him like this, Oppa clearly wasn’t satisfied. So what if I offered him my well-prepared onahole pussy right after they finished?

‘He’d wreck me so hard…♡’

And so, after one of the rare times Oppa had sex with his girlfriend…

They didn’t even do it that much. Just some kissing and whispering “I love you.” At first, seeing that hurt, but now I didn’t care. It was obvious Oppa wasn’t satisfied.

Sorry, sis, but Oppa can’t be satisfied without my pussy. What’ll happen if this keeps up?

‘…Is this NTL?’

Huh. In manga, it’s usually the guy stealing the girl.

But I guess that’s just manga logic.

A little later, my sister started dozing off. Oppa still had a loving expression, but his rock-hard cock clearly wasn’t satisfied. Watching him, I kept my pussy ready until he signaled for me to come out.

“Hey, since noona’s asleep now… Were you masturbating in there?”

Oppa, who was about to send me away, widened his eyes when he saw my state. Of course, his dick got even harder.

Plus, after being in the wardrobe for so long, the moment the door opened, the scent of a horny girl filled the air. I carefully reached out and stroked Oppa’s cock.

“You didn’t get enough, did you?”

“…N-No, I did.”

Anyone could see he wasn’t satisfied. I carefully climbed onto the bed, positioning myself next to his girlfriend, and stuck out my ass. Oppa looked like he wanted to say something, but with her right there, he couldn’t speak up.

Of course, that wasn’t the only reason. Right now, my pussy was dripping with arousal, perfectly ready to be eaten. I glanced at my sister beside me and swayed my hips seductively. Strings of my juices dripped down, but she was fast asleep, not even stirring.

“So, Oppa.”

I asked in the lewdest voice I could muster.

“Wanna try some secret onahole affair sex… behind your girlfriend’s back?”
