Chapter 103: Doppelganger Younger Brother (6)
Squish—
“H-huuuh…♡”
As he rubbed his cock against my drenched hole, it slid inside as naturally as if it were lubricated by the friction itself. To think a fake younger brother was raping me with a cock modeled exactly after my real brother’s. My waist trembled uncontrollably, and strength surged into my limbs.
‘But wait, does this even count as incest?’
Even if the shape was identical, he was a different person. Technically, shouldn't this just be judged as using a dildo modeled after my brother’s equipment?
But my trivial worries were short-lived as I gasped at the pleasure that far exceeded my expectations.
“Heugh…!”
I curled my toes and gripped the bedsheets with my fingers. Just from having a cock inside me, my pathetic pussy began to spray jets of fluid like a weakling.
“Are you a baby, Sis? Pissing right in front of your brother… aren't you ashamed?”
“T-this isn't piss…! It’s not pee, it’s… the fluid that comes out when a woman feels good….”
“Aha, so it felt that good? We just started, yet you’re already feeling it this much?”
“That’s not what I meant… Heeeuh…♡”
What did I mean, "not what I meant"? The truth was that it felt good. A little too good, in fact.
“Try spraying again. Just like before, give me a big squirt. Come on, do it.”
“T-that’s not something I can just do on command… Ha-ahng?!”
“What do you know, you can do it just fine. Stop playing coy.”
“I’m not being coy… Wait?! Don’t mess with my clit…!”
“Wow, water squirts out every time I press it. Are you a water purifier or something, Sis?”
“Ah, ha-ahng♡ I’m not… I shouldn’t like this…♡”
To put it bluntly, if I hadn't been suppressing my moans to maintain some shred of dignity as an older sister, I’d probably be wailing and panting like a total mess by now. That was how incredible the power of my brother’s cock was.
‘I knew it, bigger isn't always better…!’
Even though his was on the larger side for a normal person, I’d been stretched by owners of truly monstrous cocks before, so I thought my brother’s size would be nothing special. I was dead wrong.
My pussy was strangely weak against this fake brother’s cock. Of course, I only just realized this. I already knew my pussy had a "losing matchup" against almost any cock, but today was on a whole different level.
As if coated in glue, my pussy clung tightly every time his cock entered, and when it pulled out, it wrapped around it as if begging him not to leave. Seeing it plead for him not to pull out even while my cervix was being hammered, it was truly the pussy of a battered wife.
“I don’t usually say things like this… but Sis, I think our chemistry is way too good.”
“Ha-eut♡ D-don’t say things like that…! Sexual compatibility between siblings, ha-ahng…♡”
I played coy and averted my eyes, but internally, I flinched. It was because I was thinking the exact same thing as the fake brother.
‘Maybe it’s because we’re blood-related, but it fits so perfectly…♡’
It felt like a Tetris block clicking into place inside my pussy. Every single vaginal fold tangled around his cock, urging on the mating process. Even the shape of the fake brother’s glans felt custom-made just for my pussy.
Until now, I had felt pleasure from the pain of expansion while accepting cocks that were too large for me, but the quality of this pleasure was entirely different.
Siblings are bound by heavenly decree. The fact that I had the best sexual compatibility with the one person I should never, ever share a bed with evoked an indescribable sense of depravity.
“Mi… Min-jae… Ha-eeung♡ This is dangerous… You have to, heut… wear a condom….”
“What are you even saying with that melting voice?”
“If a b-baby happens… what will we tell our parents… Hau-ut…! Pregnancy is dangerous…♡”
Flustered by how excessively well we fit together, I started rambling nonsense I didn't even mean. The fake brother burst into laughter.
“Don’t you remember the title of that porn you were watching? You said it was ‘Guaranteed Pregnancy Rape.’ I’m just giving you what you wanted, aren't I?”
“Pregnancy… Guarante-ed…?”
“Yeah. I’m going to give you a baby as a gift, using your brother’s semen in your womb. You’ll give birth for me, right?”
“N-no… If that happens, you’ll be the dad and the uncle at the same time… Our mom will become the mother-in-law…♡ That’s, that’s just… Heut…♡”
He wasn't even my real brother, and he hadn't even ambushed me while I was sleeping, so why was he trying so hard to stick to the "Guaranteed Pregnancy Rape" theme? I let out a constant stream of moans, my body twitching incessantly.
“But Sis, are you sure you don't want to be creampied?”
“Of course not… Hu-ut…! There’s no sister in the world who wants to bear her brother’s child…!”
“Then why are you locking me in place so I can’t leave?”
“……Eh?”
Only then did I snap back to reality and check what my limbs were doing.
I had been so engrossed in the penetration by the fake brother’s cock that I hadn't even realized what kind of expression I was making or what position I was in.
“H-how……?”
I was hugging the fake brother’s neck with both arms and wrapping my legs around his waist, pinning him down. I was making sure he couldn't escape my embrace.
It was the position commonly known as the ‘Daisuki Hold.’ I was no different from a bitch desperate to be held by her master.
“And you’re saying you don't want to be creampied while doing this?”
“D-don’t look at me like that……♡”
Only then did the fake brother’s face slowly come into focus. Until now, I had only felt the female pleasure provided by the cock, but I was moving one step further.
Facing the eyes, nose, and mouth that perfectly imitated Do Min-jae, a wave of shame washed over me. Along with it came a sense of depravity from committing an act that should never be allowed.
The guilt toward my real brother, who surely thought of me as family and not a woman, stimulated my erogenous zones.
“I’m sorry for being such a lewd sister…! I was… heut♡ a perverted sister who’s crazy for her brother’s cock…!”
“You’re a failure as a sister, aren't you? Hmm? Are you starting to understand what I meant by being a girlfriend made by our parents?”
“At, a-hat…! No, I’m your sister…!! Do Min-jeong and Do Min-jae are siblings…♡”
“No. From now on, Do Min-jeong is Do Min-jae’s girlfriend. A cute, slutty girlfriend who offers up her pussy whenever he asks. An obedient, devoted girlfriend who does whatever her boyfriend wants.”
“No…! That’s not a girlfriend♡ That’s just a convenient sex slave-ahng♡”
Without realizing it, I forgot my shame and started acting spoiled toward my brother. Unable to look him in the face, I closed my eyes and shook my head, but the fake brother grabbed my cheeks with both hands and held me still.
Curious about what was happening, I squinted my eyes and saw his lips approaching.
“No, you’re a girlfriend. An onahole girlfriend who’s always craving her boyfriend’s loving semen.”
As the fake brother’s lips overlapped with mine, many things happened at once. Hot, thick semen surged into my womb, and like an oil well bursting in the desert, I squirted again.
By the time I realized I was being creampied, the fake brother’s tongue was already ravaging the inside of my mouth. Without even a moment to catch my breath, I was toyed with by his tongue above and his cock below.
Even after filling my womb with semen, his cock didn't wither, continuing to torment my pussy which had grown weak from just climaxing. His tongue plundered the heart of a girl who had kissed far fewer times than she’d had sex.
Even as I was being disciplined from both ends, I couldn't push the fake brother away.
Slurp, schlopp… Squish, squelch—!
“Hau… Eungh-aat♡ I came…! I already came, so please stop now……!!”
“Anyway, to think your mental state is still intact after all this, you really are a human onahole.”
“E-ehe…? You said I was your girlfriend, when did I get demoted back to an onahole…?”
“You’re way more of a pervert than I thought. To think you’re a masochist bitch who even enjoys being raped by her brother….”
The fake brother had an expression like a man in the middle of post-nut clarity. Since he actually had just ejaculated, it wasn't entirely wrong.
However, my female switch was still flipped on. Whether it was my mental state or whatever, I didn't even care about the fake brother’s true identity right now.
The man right there, in front of me. The man who looked like my brother. I just wanted to have my pussy tormented while being treated like an onahole instead of a sister. That was the only thing I could think about.
“I’ll have to change direction. I should just train you to follow my orders unconditionally. Even if it takes a little time…….”
“D-direction…? Are you going to do it from behind this time…?”
“Behind? Ah, that’s a good idea.”
As soon as I got the go-ahead, I turned around and stuck my ass up in the air. Whether he poked into my pussy, which was dripping with semen, or went straight for my anal, I didn't care. I just craved the cock.
“Wait a second.”
When had he even checked? The fake brother took out the slime I had kept in a bottle on my desk, tossed it onto my pussy, and went out to the living room.
Seeing that he knew slimes were used for cleaning female bodies showed he was skilled at handling monsters, but I didn't have enough brain capacity left to follow that train of thought.
“Here, I brought it.”
The fake brother set down the trunk he had brought to our house in front of the bed. When he unzipped it and revealed the contents, my jaw dropped. Inside were nothing but items used for sexual purposes.
“This should be good.”
After scanning the contents for a while, the fake brother picked something up. It looked a bit like tanghulu, or like a bead necklace that had been unstrung and laid out in a line.
I wanted to pretend I didn't know what it was, but cruelly, I knew the name of that adult toy.
“T-that’s…….”
“These are called anal beads. I’m going to put them in your ass now.”
“Why……?”
I covered my lewdly twitching anal with both hands. I was afraid that if I showed the hole clearly, he’d realize I was actually looking forward to the anal beads going in.
“Because I have to go somewhere and come back. I want you to think of me while feeling the anal beads stuck in your ass.”
“W-where are you going……?”
“I’ll be back soon. So you shouldn't leave the house either, Sis. We might miss each other.”
Going somewhere? That was nonsense. I already knew his true intentions.
For whatever reason, the fake brother wanted to completely break me. Unless I was an idiot, I had to realize that this was the start of neglect play for the sake of total training.
‘Is he aiming for that kind of development?’
A woman who feels relieved to be free from a man’s clutches, only to find herself horrified a few days later as she masturbates, desperately longing for the man who treated her so roughly.
I’m actually quite fond of that trope, but the thought of being neglected with such a wicked item inside me made my head spin. I was already longing for his cock right now; how much longer would I have to wait?
“That’s mean… Just stay with me… Please?”
“It’ll be a problem if you’re already missing me. You’re not going to call another man over because you can’t stand it, are you?”
“…….”
“You look like a total slut-bitch, so I wouldn't put it past you. I’ll need some countermeasures.”
The fake brother pulled out a pen and started writing something on the anal beads. One character per bead. On the anal beads consisting of seven beads in total, he wrote large letters.
“Um, what did you write?”
“Does the envelope need to know what’s in the letter?”
My cheeks turned bright red. If the writing on the anal beads was a letter, then my body, which would hold those beads, was nothing more than the envelope containing it—that’s what the fake brother was saying.
A sense of shame rose up at the insult to my personhood. Not missing the opportunity, the fake brother applied plenty of lubricant to my anal and began inserting the anal beads one by one.
“Huu-eut…….”
“Wow, does this feel good too?”
“Anything Min-jae gives me… ha-ahng…♡ I love it….”
Casting aside my pride, I let myself be completely plundered, leaving my body in the fake brother’s hands. Even as I exposed the shameful parts a woman should never show and was treated like a toy, I expressed my gratitude.
“Third one.”
“Ah-eung……♡”
However, due to the foreign sensation of something entering my ass, it felt like a very long time. The sensation of something round, not a cock, entering, settling, and staying there was not easy to get used to.
“There, all in.”
“Eut… h-eung, it feels weird….”
“Well, of course it does. That long thing is all inside your belly now. Can you see that?”
I could barely see it when I angled my ass toward the mirror. Something small was peeking out from between my butt cheeks. It was the loop of the anal beads, designed for a finger to hook into and pull.
“Wait. If I pull it like this……”
“Oho-o-ok♡♡?!”
“Be careful, because that’s the kind of sound you’ll make. I wrote on them, so I doubt anyone will dare touch you.”
So what on earth did he write on the anal beads? I wanted to ask, but I couldn't open my mouth.
It was because a master-slave relationship had already been established. Originally, since I was the older sister, I should have been more confident, but I couldn't.
‘I’ve been… conquered…….’
Having been plowed by his cock, I felt it in my bones that a female could never act superior to the male who owned that cock.
“I didn't forbid masturbation, so you can enjoy yourself with your pussy.”
The fake brother pointed to the adult toys scattered in the trunk and patted my pussy with his large hand—the pussy that now had a slime inside it, expertly sucking up the semen and cleaning it out.
“You have to be a good girl and do your ‘pussy wait’ until Master comes back, okay?”
“Ha-eut……♡”
And so, the fake brother left, and I fell into a frenzy of masturbation.
Penetrative masturbation, clit stimulation, using my breasts and nipples… but in the end, none of it could beat the sturdy body and large cock of a real man.
Even so, I couldn't stop. Even though I didn't know how long this would last.

Meanwhile, exactly six hours after the doppelganger left Floss’s house.
“Phew, that was fun.”
The real younger brother, ‘Do Min-jae,’ finished his trip and landed in Korea.
The next destination for this living variable was already decided.
“What was Sis’s address again?”
The moment he planned a surprise housewarming visit for Do Min-jeong, the timer was set.
……Only three hours left until the forced termination of the doppelganger’s neglect play.
