Sister Caught Sucking in Secret
I fell asleep without realizing it.
But the pleasant sensation I felt beneath me slowly pulled me back to consciousness.
'What is this? Is it Mom?'
I came home and fell asleep.
Mom had slipped into my room and was sucking my dick?
It felt a little awkward for that to be the case...
'Whatever, it doesn't matter.'
It's been days since Mom last sucked it.
So it makes sense that she might feel a little awkward.
Instead, I decided to enjoy the flavor of Mom's mouth that I'd missed for so long.
Clutch.
"Uwoh?!♥"
When I pressed my head down, the cock sank deeper.
She made a pained sound, but to Mom, this was nothing at all.
"Suck it properly. Or you'll get spanked on your ass until it's red."
"Ngh... ngeh♥"
'Why does her voice sound different? Must be my imagination...'
My mind was still a bit hazy.
So I didn't think much of it and pressed down even harder.
"Uwoh♥ ungh♥ hah♥ uwoh♥"
It was awkward, yet Mom's mouth clung wetly to my cock.
She was clearly desperate, acting like a bitch in heat who couldn't wait to suck the dick harder.
'Let's just cum already.'
I decided to finish it once and then wake up.
"Since you're hungry, suck it properly with your mouth."
"Uwoh♥ uuwoh♥ jjooooop♥♥"
Mom answered by sucking my cock even harder.
An intense orgasm was rising.
I pressed Mom's head down deeper.
Vurrrurrurrr!
"Uuwuuuuwuwoh?!♥♥"
Thick semen spurted out in a sticky mess.
Even if the manager had received a blowjob, the load was still there.
So the climax on Mom's mouth that I'd been missing for so long...
'Wait... something feels completely different from usual.'
If it were Mom, she would have gulped down the semen without pause and licked the cock with her tongue.
But now, even just swallowing the semen seemed like too much for her.
No matter how many days, how could it be this awkward?
A cold sweat ran down my spine.
My mind suddenly cleared as I forced myself awake, and I looked down.
"Uwoh♥.... ubwoh♥"
"Min-jung?"
"Jjooooooop♥♥"
Min-jung was still sucking my cock, drinking down the semen.
---
"T-this is... this was a mistake..."
"Guulkk♥... jjoop♥"
"Kwuk!! Step back for a second!!"
Once I realized it was Min-jung sucking my dick, my head went completely white.
I tried to push her away to make her let go, but she wouldn't move.
She kept sucking, licking the head with her tongue while my cock stayed in her mouth.
"Jjoop♥ haa... thank you for eating it... hng♥"
Finally, Min-jung pulled her mouth off and looked at me with a lewd smile.
"Oppa was trying to sneak a blowjob while I slept, but I got caught♥"
"W-what are you doing right now?"
"What do you mean♥? I sucked Oppa’s dick. And I ate so much of that thick stuff♥ bee♥"
She opened her mouth to show the semen still left inside.
"Guulkk♥"
Then she looked at me after she finished.
"Oppa looked like you were struggling, so I wanted to help."
"That's not allowed! Let's just pretend today never happened..."
"Not allowed."
I tried to brush it off as if nothing happened, but Min-jung firmly said it wasn't and grabbed my cock.
Thud thud thud thud thud
"This is Oppa’s fault♥ I was tempting you so much and you never once gave in♥"
"We’re siblings!"
"I know, but Oppa doesn't have the right to say something like that."
"What?"
Min-jung's meaningful words froze me in place.
When I was about to think "no way", she said,
"You were secretly doing this with Mom♥"
"H-how..."
"At first, if you wanted to do it without me knowing, you should have been obvious. You should have had Mom suck your cock in a place where no one could see and had sex♥"
Min-jung already knew everything.
It was quite shocking, but I had to stop what she was trying to do right now.
It didn't make sense for Min-jung and me to be in this kind of relationship.
'Move already... what is this?'
I tried to push her away and get her out of the room.
But my body wouldn't move.
My strength was completely gone; I couldn't put any strength into it.
"Actually, Oppa is enjoying this too, right? You're just sitting there quietly♥"
Thud thud thud thud thud
"Ugh! N-no."
Min-jung, who was stroking my cock, smiled as if she was right.
"Or should I stop it now♥"
"My body won't move! So stop!"
"That's an impossible excuse~ Actually, Oppa is enjoying it too, right? When my little sister strokes me with her hand, my dick gets rock hard♥"
"Kwuk!!"
Even when I told the truth, Min-jung wouldn't believe it.
She just thought I was staying still because I liked it.
"This is the first time I've ever sucked Oppa’s dick, and it felt so good♥ Tasting it for the first time, thinking it's Oppa’s, makes my pussy wet♥"
"It's not too late. So just stop now..."
"It's too late, Oppa♥ There's no rule that says I can't use Mom as my sex slave."
"What?"
"I already knew about Mom and Dad's relationship and the transfer deed."
"T-that's..."
"I accidentally found out too. But I thought Mom was just putting her laptop and files in the storeroom, so..."
Thud thud thud thud thud
"Mom really gave the transfer deed to Oppa♥"
"How did you know?"
"I sneaked into Mom's room when the atmosphere was weird and looked at it. Oppa signed it too♥"
Min-jung was often alone at home.
She said she had already seen the transfer deed after sneaking into Mom's room.
"She didn't just like to enjoy it as parents, she knew Mom is a real sow, and Oppa is Mom's owner♥"
Min-jung knew everything.
That was why she was acting so boldly right now.
"I became like Mom, and it seems our tastes and tendencies are the same too~"
"Min-jung..."
"Did you know how much I masturbated while fantasizing about Oppa raping me?♥"
"..."
My sister's shocking words left me speechless.
"I wanted to get married to Oppa since I was little♥ When I first discovered hentai, I was looking for really hard stuff from the beginning♥"
She spoke honestly about her own hidden and lewd nature.
And it was obvious who she took after.
"How much I wanted to be ra*ed by Oppa♥ I wanted to be a meat toilet or a cumdump instead of being a little sister♥"
"We're siblings, first calm down."
"No♥ It's already too late. I know why I became a model? I worked so hard on my body so that Oppa would want to devour it♥"
Min-jung had excellent looks and a perfect body, but none of it was completely natural.
She worked out and took care of herself diligently.
It was genius-level effort.
"Being a model means I can earn a lot of money, so even if Oppa becomes unemployed later, I can take responsibility♥"
"No, that's..."
"Actually, being unemployed is better♥ Then I can be devoured every time I'm at home♥"
A sexual tendency that had crossed the line into madness.
It was natural to think she was very similar to Mom at the same time.
Mom became her son's sex slave because she couldn't hold back her desires.
And her little sister, who had the same tendencies and desires, was sucking her own brother's cock.
Thud thud thud thud thud
"Oppa was pretending not to be, but you got excited by my body♥"
"No."
"Really? Even now your dick is standing rock hard♥"
"..."
I wanted to deny it, but it was difficult.
My cock was already rock hard.
Even in my sleep, I started crossing the line while Min-jung sucked my semen from my cock.
"I know you twitch every time my chest touches you even when you sleep♥"
It was Min-jung who had deliberately pressed her chest against me.
I had thought it was just a joke and let it go, but now I realized it was intentional.
"Because of Oppa, I'm so excited too."
Itch.
"Hng♥"
Min-jung put her hand between her legs and pulled it out.
Her fingers were wet and covered in lewd fluid.
"It's okay♥ It's just that I'm becoming Oppa's sex slave just like Mom♥"
"We're siblings..."
"Having sex with Mom is way better! And we don't even share blood♥"
No matter what, we had grown up as siblings since we were little.
It was difficult to change that relationship now.
I had always seen her as just my little sister until now.
"Min-jung. You are my little sister. Little sister!"
"I know♥ But from now on, I'm Oppa's sex processing meat toilet little sister♥"
She had already made up her mind.
Even in the middle of this, my body still wouldn't move.
"Oppa, if you had no such feelings for your little sister, you wouldn't have held back from cumming, right?"
"Ah, no... ugh!!"
"Oppa, if you don't cum with my hand, I'll give up, but otherwise♥"
Thud thud thud thud thud
Min-jung's hand was speeding up.
She was stroking my cock up and down, giving it stimulation.
An excitement level so intense it was hard to endure came rushing in.
A strong pleasure so intense it was impossible to hold back came rushing in.
"Oppa’s dick is twitching♥ Is it because little sister is stroking it with her pussy?♥"
Thud thud thud thud
Min-jung smiled leisurely as if she already knew I was about to cum.
"Even if I just use Mom, it might get boring♥ I'll become Oppa’s second sex slave♥ gulp♥ jjoop♥ uwoh♥"
"Kruuuuk!!"
She casually lifted my t-shirt up and sucked my nipple.
Even though it was happening to me with my little sister, I could no longer think of it as something I could stop.
"It's okay♥ Oppa is going to cum a lot with your pussy♥"
"Min-jung!! Uuwuuugh!!"
Vurrrurrurrr!
Finally, the semen spurted out.
Even though it had already cum once, the semen that spurted powerfully rose high and then fell.
"Haaaa♥ It's an enormous amount♥ You stuffed all of this into my mouth♥ gulp♥ jjoop♥"
Min-jung licked the semen off her hands and made a lewd smile.
"Then Oppa has admitted it. You got excited seeing your little sister♥"
"That's..."
I wanted to deny it, but I couldn't.
Because what Min-jung said was true...
"It's okay, Oppa. It's just that we're getting closer than before♥"
Smiling as if she had been waiting, she took off her clothes.
Plop... gush...
Min-jung quickly took off all her clothes and stood naked.
She said while climbing on top of me.
"Then Oppa... take my virginity♥"
