Chapter 101: Doppelganger Younger Brother (4)
Chapter 101: Doppelganger Younger Brother (4)
Rationally, I knew. I knew there was no way he could smell anything. To begin with, compared to a bathroom filled with the scent of body wash, the smell of my own fluids would be nothing more than a drop in the bucket.
But the truth didn't matter. What the fake younger brother was aiming for was to rattle my mental state. It was a clear attempt to make me waver and naturally draw me into the flow he was directing.
'Well, I guess this much is...?'
I didn't want to surrender too easily, but since this wasn't that extreme, I decided to play along a little. If I flinched while acting slightly embarrassed, it would probably be a satisfying enough reaction for him.
"I told you, it's hard to wash you if you keep your legs pressed together like that. Your thighs are so plump, Sis."
"...I'll have you know I take good care of my figure."
Even without putting in much effort, my powers as a Magical Girl tended to keep my body shape consistent. When I spoke poutily, the fake younger brother lightly pinched my thigh and tried to pry my legs apart.
"I'm just washing you... right? It's nothing weird. We're just taking a bath."
"Of course. It's not like you're the only one getting washed! You're going to do the same for me afterward, so why be like this?"
"Wait, me too?"
The fake younger brother tilted his head as if he were stating the obvious. Come to think of it, the next scheduled step after he finished washing me was for me to wash him.
"Now, now, here I go~"
"Hyuut?! Y-you should give me a warning before you go in!"
Whether he was annoyed by my hesitating and dragging things out, the fake younger brother simply put his hands together, thrust them between my thighs, and forced the gap wide open. I was swept away by that forceful strength before I knew it.
"Ha-aaang...!"
In the end, I couldn't stop his hands. Those wicked hands rubbed the insides of my thighs, lathering them with bubbles and kneading them as if tickling me, while also ravaging my knees and calves.
"Hng... but, u-uuhm..."
"What's wrong, Sis? Is there something you're unsatisfied with?"
"Huh? O-oh, no! It's nothing like that, just..."
I could never say it. I could never say that I was burning with impatience because he was only touching my legs and not my pussy. The moment those words left my mouth, I would become a crazy perverted sister begging her brother to touch her pussy.
However, it was true that the sexual desire inside me was swelling. And it was happening right now, very rapidly. Especially whenever the man's fingers brushed against the inside of my thighs, it was hard to hold back my moans.
'He won't... fuck me right here, will he?'
From the looks of it, this fake younger brother was the type to take his time when hunting prey. Seeing as he wasn't touching or poking my pussy right away, it seemed like he was laying the groundwork for female domination through proper training.
"You're relieved now, right? I told you I wouldn't touch anywhere strange."
"Y-yeah. Thanks. Or, is 'thanks' even the right thing to say...?"
"Pwahaha! Since when did you get so cute, Sis? Did you find someone you like?"
"What are you talking about! Where would I find someone I like?"
"Well, they say women change when they fall for someone."
The fake younger brother was just making up excuses shamelessly, knowing nothing about the old me. But his face and voice, which were chillingly similar, made it seem as if my real brother were the one saying those things to me.
The shame was doubled because I imagined it wasn't some stranger, but the brother I knew, Do Min-jae, saying that. I was already hesitating because I felt like I was becoming too much of a female lately, and he chose the perfect timing to strike deep.
'I want my pussy to be stroked... ♡'
I didn't even hope for fingering or cunnilingus. I just wanted him to pat or rub my wet pussy with that large palm of his to provide enough stimulation.
It was like a situation where someone shows food to a dog and commands it to 'Wait' so it can't swallow it immediately. Similarly, it seemed he had no intention of touching me easily, as if he were trying to train me with 'Wait' discipline.
'A woman begging to have her pussy touched.'
There was nothing more unsightly than that. Especially if the person was her brother. Driven by necessity, I braved the shame and thought of a way to get my pussy stroked regardless of the fake younger brother's will.
'I can just sit down, right?'
The fake younger brother's hand was still between my legs. And his palm was facing upward. If I pretended to slip and sat down here, I might be able to get my pussy stroked without getting caught.
Of course, matching the position wouldn't be easy, but it was a gamble worth taking. Since there wasn't any particular risk, I didn't hesitate and executed it immediately.
"You're done washing, right? Then I'm going to sit down now."
"Huh? Oh, wait a second..."
"What do you mean 'wait a second'? My legs hurt... Hiyaaaa-at?!"
Having accumulated plenty of experience in defeat play, I was now capable of putting on a top-tier performance. I let out a coquettish shriek, pretending to lose my footing and slip while trying to sit.
As planned, I landed my buttocks softly on the bath stool. Of course, the fake younger brother's hand was between my buttocks and the stool. To be precise, I had sat on his palm with my pussy.
"Ha-aaang♡"
Unlike a moment ago, a voice completely devoid of pretense burst out. Aside from my pussy slamming down perfectly onto his palm like a stamp, it was the aftermath of the fake younger brother's extended fingers brushing against my clitoris.
"Hey, why did you sit down so fast?!"
"Hng... hyuut...! Hyii-it...♡"
"Don't just sit there, hurry up and lift your butt! Let me get my hand out!"
Rarely, the fake younger brother also poured out words in a flustered tone. It seemed he couldn't distinguish whether it was acting or intentional. Since I intended to disguise it as an accident, I had to regretfully let go of the pleasure that had briefly visited me.
"S-sorry... I'm just impatient...♡"
"Phew, I thought my hand was going to get crushed."
The fake younger brother also acted the part of a casual sibling, grumbling about being crushed by his sister's unnecessarily large royal ass, but a strange heat lingered on his face.
Well, even from the perspective of the one doing the training, it wouldn't be easy to hold back with a delicious-looking pussy right in front of him. He was trying to look at the forest instead of the trees, but when a tree pushes right into your face, it's hard to see the forest no matter how wide your vision is.
"Now it's your turn to wash me, Sis."
"I know that even if you don't tell me. Wait, where was the shower ball...?"
"What shower ball? I squeezed soap onto my hands to wash you, so you should do the same for me!"
Even though my true heart wanted him to point out that exact part at the right timing, I raised my voice to refute the fake younger brother's sophistry.
"Where's the logic in that! A shower ball is much easier for making lather!"
"Sigh, is being 'easy' what's important right now? You have to look at the affection and sincerity between family members! Things like that!"
"Is washing with your hands 'sincerity'? What on earth does that even..."
"Or what, if you hate using your hands, would it be better if I just applied soap all over my body and you washed me with your body?"
I couldn't answer that question and just stammered. Washing someone by applying slippery liquid all over your body—that was essentially no different from a Japanese soapland, wasn't it?
Of course, if it were defeat play, acting like a whore would have its own appeal, but for now, the concept was strictly siblings. No matter how you looked at it, acting like a soapland girl washing someone with her whole body didn't fit.
"Fine. I'll do it with my hands! I'll do it, okay!"
"Good choice."
In the end, I decided to wash him with my hands, and just as the fake younger brother had done, I squeezed a generous amount of body wash onto my palms. I wiped down the fake younger brother's torso with it and worked hard on his lower body as well.
Touching a man's firm body was certainly arousing, but from beginning to end, my nerves were focused on the object hanging between the fake younger brother's crotch. Even while I was wiping everything from his shoulders to his stomach, waist, and limbs, I could only think about his cock.
"Sis, aren't you going to wash here?"
"Huh?"
However, even though I kept staring at it, I didn't touch it. Was this an expression of revenge for the fact that the fake younger brother hadn't directly touched my pussy? Or was I simply embarrassed to touch my brother's cock?
"Y-you didn't wash there either. So we're even..."
"That's because you were embarrassed, so I avoided it. I don't mind, though?"
"...Huh?"
"I told you. I don't really care if you touch my cock, Sis. Why are you being like this between family?"
How could he be so shameless as to impersonate family in front of someone he was meeting for the first time? I knew he wasn't real family, but I couldn't completely ignore his appearance.
"W-washing that place between family is a bit..."
"Didn't Mom do it when we were little? You're going to have to be a mother someday too, Sis. Think of it as practice."
He really had a silver tongue. For a moment, I found myself imagining it, as if possessed by the fake younger brother's words. Myself, as a mother, washing the body of my young son.
"Why are you so shy when you're a Hero? Are you really a Hero?"
"That and this are different..."
"If you're really that embarrassed, just close your eyes. I'll lead you."
I hesitated for a moment, but eventually, I closed my eyes and reached out my hand. Rather than touching it of my own will, I thought it would be more arousing to be led by the fake younger brother while touching his cock.
"Here, this way."
The fake younger brother's hand, which was larger than mine and had calluses here and there, grasped my hand. To be precise, he held my wrist and pulled it toward his cock, letting me flick the glans.
"Hng..."
"What's going to happen if you just flick it like that? If you want to wash it, you have to grab it tight and rub it hard."
"Won't that h-hurt...?"
"As if you wouldn't be able to control your strength. Besides, mine is firm, so it's fine."
The fake younger brother only guided the direction; the actual grabbing and kneading was my job. While my face turned beet red, I complied with his request and massaged the large, long rod.
But something was strange. I had already applied plenty of lather and used enough water, but he wouldn't let me take my hand off his cock. Furthermore, I could feel that the fake younger brother was quite aroused.
"Um... are we still going?"
"Yeah, it still feels dirty."
Since I couldn't see with my eyes, my other senses felt even stronger. My hearing perfectly captured the fake younger brother's excited breathing and moans, and my sense of touch infinitely enjoyed the hot, hard cock.
I felt sorry for my senses of taste and smell. Right now, I wanted to lower my head, sniff the scent of the cock, and take it into my mouth to suck on it, satisfying my temporary urges.
'That's too much of a sudden acceleration... let's hold back...!'
For the sake of natural play, I suppressed my overflowing sexual desire and only massaged it with my hand. At this point, it wouldn't be strange to call this handjob-like stroking an actual handjob.
"Ngh, hng... good, just a little more like that..."
"L-like this?"
"Hide your nails, and shake it up and down or stroke it long... ngh...!"
"I'll wash down here too...! Because it seems like it would get dirty easily...!"
"E-even my balls? Ugh...! This is the best...!"
Gradually, I also became absorbed in the handjob. Should I say I started doing it with all my heart? Touching a cock that looked exactly like my brother's while my vision was blocked was a special experience.
'Feeling like a sister who's taking care of her brother's sexual needs... ♡'
My breathing grew ragged. It wasn't just the fake younger brother; I was the same. Having noticed each other's excitement, the deep lust propagated back and forth, swelling rapidly.
There is always a limit to how much something can swell. The fake younger brother's cock, which was as erect as it could be, finally fired its celebratory cannon. It squeezed out the white liquid meant to impregnate a female.
Byut! Byurut! Byubyubyubyut!

Some of it stuck to my hand and hair, and the rest splashed onto my body. Almost none of it fell to the floor.
"H-hguuk?!"
Feeling the hot, sticky semen on my body, I fantasized. What would my brother's semen taste like? What kind of scent would it have? Since we're genetically similar, would it feel different somehow?
As I froze up, suppressing the urge to lick the semen off my hand right then and there, the fake younger brother spoke to me in a much more refreshed voice.
"Sis, we're all done washing now."
"I-is that so? But by any chance, what just fell on my body was..."
"Oh, that's nothing. You can just wipe it off. Do you want to keep your eyes closed?"
The fake younger brother grabbed the showerhead and sprayed a stream of water toward the parts of my body where the semen had landed. When I opened my eyes, there were no visible traces left, but I could still feel a strange stickiness and scent.
"Then I'll head out first, so take your time coming out."
I could have scrubbed myself clean with soap after he left, but I didn't. I enjoyed the stickiness of the semen. I savored the traces of the bukkake the fake younger brother had left on my body.
"Haah... ♡"
Just breathing caused lewd breaths to pour out. In my heart, I wanted to masturbate several times just like this. Recalling the fake younger brother's body and cock, and his flirting comments.
However, knowing that masturbating while already in heat was no different from pouring water into a bottomless pit or drinking seawater when thirsty, I endured it.
'He'll definitely come find me tonight anyway. It won't be long. I'm not the only one in heat.'
The panties I had just changed into became damp as soon as I returned to my room. I couldn't suppress my sexual desire at the thought that the fake younger brother might knock on my door and enter at any moment.
He said he would sleep in the guest room, but that was 100 percent a smokescreen. He will definitely come into my room. He might ask before entering, or he might sneak in after I've gone to bed.
'Then should I pretend to sleep quickly? What should I do?'
In times like this, testing it out is the best. For one hour, I intentionally made noise as if I weren't sleeping, and for the next hour, I turned off the lights and lay down without making a sound, pretending to be asleep.
However, there was no sign of my door opening.
'...Not yet?'
Another hour passed after that, making the total waiting time three hours.
'When the hell are you coming?!'
Magical Girl Floss, facing the greatest crisis of her life.
In heat for three hours, but the fake younger brother won't attack.
