Chapter 102: Doppelganger Younger Brother (5)
Chapter 102: Doppelganger Younger Brother (5)
By the time the wait reached the three-hour mark, I couldn't help but think that something had gone seriously, fundamentally wrong.

‘Just when the hell is he coming?’
There’s a limit to neglect play. This was crossing the line. He’d let the rice simmer for so long it was practically ruined. The door I’d left slightly ajar, an open invitation for him to enter at any time, now just looked pathetic.
Part of me wanted to fling that door wide open and go check on the situation, but doing that would make my intentions way too obvious. It would be incredibly suspicious to suddenly pop out after pretending to be asleep just a moment ago.
‘What is he planning?’
There was only one fact I could confirm right now. That fake younger brother was the type to tease and condition a woman until her heart was practically charred with anticipation, driving her absolutely insane.
If I’d known it would be like this, I would’ve taken a cold shower to force my libido down and just gone to sleep. But since I’d maintained this state of arousal for three whole hours, the sunk cost was simply too high.
If you compared the intensity of my lust to a fire, back in the bathroom, it had been a massive blaze capable of melting even Arctic glaciers. However, I hadn't maintained that level of power. If I had, I would’ve exhausted myself and collapsed.
Eventually, I’d turned down the heat. I kept it as a lingering ember, just enough to feel a faint warmth and hear the occasional crackle. Thanks to that, I wasn't hit too hard, but…
‘The fact that I’m waiting anxiously is still the same!’
Once you’ve lit the fire of lust, you can’t just put it out easily. Arousal doesn't just vanish because you’re sitting still. Even using various toys by myself barely resolves it, so the idea of just lying down and sleeping was completely unrealistic.
I felt depressed. Disappointed. Annoyed.
I pouted and sat down in front of the computer. I held the mouse in one hand and a dildo in the other.
With the hand on the mouse, I began digging through folders to find fap material that could satisfy my arousal, while the dildo rubbed against my pussy over my panties, heightening my sensitivity.
“Hngh…!”
I must have been turned on for a long time, because the moment that thick, hard object touched me, my pussy honestly began spitting out juice. If it was this good with just a dildo, I couldn't even imagine what it would be like when the real thing went in.
“Hu-ung?!”
While scrolling through the folders, a familiar title caught my eye, making me jump and tremble. My pussy sprayed even more fluid than before.
Ignoring my nipples, which were standing so sharp they were visible through my thin camisole, I read the title of the video.
‘This… it’s incest erotica….’
When on earth did I save this? I felt like I remembered seeing it, but then again, I didn't. My memory was fuzzy. However, it was a work that suited this current situation perfectly.
Click.
As if possessed, I clicked the video to play it. Before I knew it, I had stripped off my panties and was frantically ramming the dildo into my pussy.
‘What is this… masturbating to incest porn while waiting for the brother who’s coming to eat me… I’m such a pathetic bitch…♡’
My thoughts were crude, but my body was honest. Soon, I had my earphones in and was so immersed in the video that I didn't even hear the sound of footsteps approaching from outside.
…I had already forgotten that I’d left the door slightly open.

Ironically, the Doppelganger staying in the guest room was having similar thoughts to Magical Girl Floss.
‘What is it…? Something’s weird…?’
A bizarre sensation. The Doppelganger’s animalistic intuition, honed through years of being a villain, was warning him. Something was wrong.
‘It’s too easy…!’
In fact, before starting the operation, he’d thought the difficulty would be quite high. After all, his opponent was no ordinary hero.
He expected everything to go smoothly once he actually ambushed Floss in the form of her younger brother. The problem was everything leading up to that.
There might be topics of conversation that only Floss and her real brother knew about, things the Doppelganger wouldn't know. If he couldn't answer naturally, he’d inevitably be suspected.
It was an unavoidable limitation of using the Doppelganger ability. Even though he’d trained to be a smooth talker for such situations, it was merely a supplementary measure.
Still, if he did get caught, there were secondary plans. It wasn't like her brother was the only man around Floss; he could find plenty of other candidates to carry out the rape operation.
Family members like her dad, uncle, or grandfather. Or colleagues and fellow heroes like the Operator or the Association Chairman. Being raped by any of them would cause mental trauma no less severe than being raped by her brother.
But there was a more serious problem.
‘I heard that Magical Girls have incredible sensory abilities.’
If the Doppelganger’s ability itself was detected just by being looked at, it was game over. His mimicry ability replicated a target’s form with 99.99 percent accuracy, but if a Magical Girl’s senses were sharp enough to catch that 0.01 percent difference…
‘Then I’m just fucked.’
And right now, the Doppelganger was feeling that sense of alarm. The danger-detection sensor ringing in his instincts ordered him to withdraw from this place immediately.
However, things had gone so well that it felt like a waste to leave. The Doppelganger was human, after all, and simply chickening out and giving up this opportunity felt like a loss.
After nearly three hours of agonizing over it, the Doppelganger decided to withdraw and stepped out of the guest room. He figured he didn't have to finish the mission today, so he’d take his time.
“Sis, a friend called, so I think I’m gonna head out…”
Just as he was about to make up an excuse and escape, the Doppelganger heard it. A woman’s moan drifting through the slightly open crack in the door.
Even as he thought the pitch-black crack in the door looked like a Venus flytrap, the Doppelganger moved toward it as if possessed. The moans, the squelching of a pussy, and the sound of splashing fluids played a triple concerto.
Creeeeak…
The moment he pushed the slightly ajar door wide open, a smile spread across the Doppelganger’s face. He finally realized why this woman had been so easy.
Several highlights entered his vision at once. The incest porn playing on the monitor. Floss in her civilian state, face flushed red with earphones plugged in. The dildo ramming into her weak pussy.
‘A sister masturbating to incest porn while her brother is in the next room… this is just…’
The Doppelganger knew a few words to describe a woman like this.
‘She was just a total airhead bro-con bitch.’
Detecting a Doppelganger? A Magical Girl’s senses? It was all absolute bullshit. Nothing but groundless worries.
This woman was simply venting the lust she’d built up from her hectic hero life through a forbidden fetish for her younger brother.
The Doppelganger hid his blooming smile, his lips twitching as he approached Floss.
“Hey, Sis?”
“Ooh… ha, haah…! I’m going again… ngh, ahhhn♡”
Even when called from behind, Floss didn't snap out of it, too focused on her masturbation. It was only after the Doppelganger pulled out her earphones and tapped her shoulder that she realized the situation.
“……Huh?”
“Are you busy?”
“Eh? I-I mean… why are you… here….”
“I was going to head out because something came up, but I thought I should tell you before I left. The door was open, anyway.”
“Ah, eek… I, I didn't lock the door…?”
Floss looked back and forth between the Doppelganger and the wide-open door with half-lidded eyes before her mouth fell open in shock.
“H-Hiiiiieeeee?!”
Only then did Floss hit Alt-Tab to hide the incest porn displayed in full screen on the monitor. She pulled her top down to barely cover her pussy and sat on the dildo to hide it with her butt.
But she knew it was all in vain. She knew it was already far too late. Even knowing that, the realization that she’d been caught doing something ‘forbidden’ made her panic and try to hide it after the fact.
The computer chair seat she couldn't hide had already turned a dark shade from her pussy juice. There was no room for excuses. The Doppelganger stared at her, curious to see how this lewd ‘sister’ would try to talk her way out of it.
“……Um, Min-jae.”
“Yeah, Sis.”
“I’ll buy you chicken, so c-could you pretend you didn't see anything……?”
That was the solution she came up with after all that thinking? The Doppelganger couldn't hold back his laughter anymore.
“Pfft, hahahahaha!”
How could such a cute creature exist in this world? He burst into laughter, wiping away a tear that escaped because he laughed so hard. Then he spoke, his tone a command disguised as a request.
“First, why don't you get up?”
“Huh…?”
“I’ll think about pretending I didn't see anything. I need to use the computer for a bit.”
Floss didn't even try to make a useless point like there being a computer in the guest room as well. She knew exactly what the Doppelganger wanted.
“Wow, it’s soaking wet.”
The Doppelganger let out an exclamation as soon as he sat on the chair seat, which was drenched in Floss’s pussy juice. Floss stood right next to the chair like a criminal, fidgeting restlessly.
“Now let’s see. What was our sister watching…?”
“W-Wait! You said you’d pretend you didn't see!”
“When did I say that? More importantly, let’s read the title.”
“Anything but that… please….”
“You have to ask politely.”
“P-Please don't read it…….”
Floss even went so far as to drop to her knees right there. A hero sister kneeling on the floor where a dildo was rolling around, hands gathered neatly, looking up at her younger brother sitting in the chair.
‘Even though I’m not her real brother, the sense of immorality is insane…….’
The Doppelganger was impressed, but as always, he had to do what needed to be done. Without a shred of mercy, he began reading the title of the porn Floss had been watching.
“You don't look very polite.”
“W-Wait! You really can't!”
When he first walked in, he’d already figured out it was the incest genre from the subtitles on the monitor, but the title was even more spectacular.
“My Wife Born of My Parents… While My Sister Sleeps… Guaranteed Pregnancy Intense Rape…?”
“N-No! It’s really not like that! The title is just an error!”
“Hmm, I see. So a sister is a wife born of one’s parents. Then to you, I must be a husband born of your parents? Want to try calling me ‘honey’?”
“Uuuuu…….”
“Or should I sneak into your bed while you’re sleeping and do this… what was it… Guaranteed Pregnancy Intense… R-Rape? Do you become a wife once I do that? I guess a married couple needs a baby.”
Floss didn't give any answer to the Doppelganger’s provocation. She just hung her head, her face beet-red, and whimpered.
She didn't make any ridiculous excuses like her tastes being separate from reality, or that she clicked it by mistake, or that a friend sent it to her. To the Doppelganger, it looked like she had given up resisting.
‘Of course she has.’
If the man in front of her were someone other than her brother, it could be interpreted that way—that she’d given up and decided to let it happen. But because the Doppelganger had transformed into her brother, the story was different.
‘Even at this point, she feels safe. She believes that because he’s her brother, he won't go any further. She trusts that he won't cross the line.’
Of course, the Doppelganger wasn't her real brother, and such a line didn't even exist for him. He stood up to shatter Floss’s arrogant complacency.
“So you like this kind of stuff, Sis.”
“W-What are you trying to do…… Kyah!”
The Doppelganger scooped up Floss’s light body. Then he threw her straight onto the bed. It was a queen-sized bed, excessively large for someone living alone.
“What do you think? I’m going to do what you like, Sis.”
“Y-You… hah…♡”
“Actually, should I call you my wife born of my parents instead of Sis?”
The Doppelganger lay down next to Floss, who had been tossed onto the bed, and firmly squeezed her butt. Floss only flinched slightly; she didn't resist violently.
At that moment, one word came to the Doppelganger’s mind.
‘Success.’
The success of the operation was right before his eyes.
*
At the same time, Magical Girl Floss was secretly celebrating with a similar thought.
If the Doppelganger was celebrating the success of his operation, the difference was that Floss was celebrating the success of her long wait.
‘YES!!!! Holding out pays off!!!!’
Three hours of waiting wasn't in vain.
Floss gulped as she felt the giant cock moving between her legs.
