It's Become Completely Natural
It had become completely natural now. The two of us siblings entered the bathroom together as if it were the most ordinary thing in the world.
“....... Just shower quietly.”
While I stripped off my clothes, my sister was still watching me, gauging my reaction.
“Who said anything?”
“You’re not saying anything, but....... that thing of yours is.”
I lowered my head, following her gaze.
“Ah, it’s always like that. Don’t mind it. Hey, buddy, behave. You’re scaring your pretty sister. Come on, relax now.”
“Fuck. How could anyone not mind? Having their little brother get hard right next to them?”
“What does it matter? We get hard when we shower together anyway. Hurry up and take your clothes off. We’re busy today.”
“Hey!”
While she stood there hesitating, I yanked her bottoms down in one swift motion. Her pants and panties came off together.
“Huh? Why are you putting them back on?”
She punched me with her fist and quickly pulled her bottoms back up.
“I-I do have to take them off. But you did it so suddenly that I got startled!”
“Unbelievable. I take them off for you and you still complain.”
“Fuck. Who asked you to take them off?”
“Anyway, take them off quickly. So we can wash up and get out of here.”
You’re the one stalling. Look, I’m already naked.
“Ha....... shit.”
“What? Regretting coming in with me?”
“Fucking hell.”
“Hey now. I helped my sister who can’t even undress herself properly, and instead of thanking me—”
Seeing her keep fiddling with her clothes was so frustrating that I grabbed her bottoms again.
“Stop using your hands. Let’s get this done and go. Yeah?”
When I reached for her waistband again, she slapped my palm, but I still pulled her pants and panties down.
“Our pretty pussy. How have you been? Oh. Why are you already wet? Did you want to show me so badly?”
Kissing between her legs was just a bonus. I pressed my lips right against the perfectly parted slit.
“Fuck. Stop!”
“Ah, ah. Wait a second. I just gave it a hello kiss. I didn’t even use my tongue.”
In return, she grabbed a fistful of my hair. If I ever went bald, I’d have to cut hers off and make a wig.
“Here. Arms up, Yunseo.”
I reached out to finish removing her top.
“....... Hey. Now that I think about it, you could have taken it off from the top first.”
“It’s my choice. You should have undressed yourself if you minded so much.”
“....... You perverted bastard.”
“The perverted bastard would be the kid if we have a baby. I’m just a pervert. Pervert.”
“Are you going to keep talking shit? Did you rent out my pussy or something, fucker?”
“It’s not a rental. Since you’re mine, it’s owner-occupied if anything.”
I pulled her into a tight embrace.
“Stop trying to gloss it over with your shitty tricks. I swear I’ll beat the crap out of you like a dog the second I get the chance.”
“Why beat a cute dog? Stop with the bad words and let’s just shower.”
I turned on the shower. The water wasn’t warm yet, so I quickly rinsed my feet first.
“You keep getting on my nerves, so of course I’m getting more irritated. Ah, shit.”
“Yeah, yeah, I got it. So, should I wash your breasts first? Or your pussy?”
“I want to wash that filthy mouth of yours first. With bleach. Or pesticide. Cyanide works too.”
“All three of those aren’t meant for people. Two of them can’t even be used for cleaning.”
“You’re not a person. You’re a beast.”
“Even animals would get you arrested if you used that on them.”
“Oh, right. Since you’re worse than a beast—a piece of trash—it’s fine then.”
“Stop yapping and just wash already.”
“Ack! It’s cold!”
I turned the showerhead toward her. She tried to grab my hair again, so I quickly caught both her arms. I couldn’t let her keep snapping at me, so I pushed her back against the wall.
“Why? Were you going to brush it off with another kiss?”
“....... I was planning to, but judging by the look on your face, I don’t think you’d let it slide.”
“Go ahead and try it. I’ll bite your tongue clean off.”
“Sis. I was wrong too, so can’t we make up? We need to hurry and get out.”
“You were the only one who did anything wrong. Why are you including me?”
“Okay. I was wrong. So let’s wash up quickly.”
“Using excuses again.”
“Won’t my kind sister forgive me? Please?”
Steam was finally rising. The water falling on my feet had warmed up nicely, so I poured it over her head. Then I squeezed out some shampoo and worked it into a rich lather. I massaged her scalp firmly with my fingertips.
“....... You know, I’m the one who writes erotica, but the way you spout filthy sexual harassment is way worse.”
“It’s not sexual harassment. It’s simply expressing my love.”
“Saying you’ll get your sister pregnant is expressing love? You crazy bastard.”
“When a man and a woman love each other, they show each other their pussy and cock. They let them meet, too. Just like we’re doing right now.”
“Fuck. When have our cock and pussy ever met?”
“Right now.”
I grabbed my cock and pressed it against her. Even though it was just a light touch on the outside, her reaction was intense.
“Uwaaak! Hey! It hurts!”
She bit me instantly. Hard enough that her teeth sank into my flesh.
“Fuck. Are you actually insane? Do you want to die that badly?”
“I was just greeting it, asking how it’s been. Wow, it’s bleeding. I should make you bleed the same way.”
She immediately understood what I meant. She snatched the showerhead from its holder and swung it at me like a whip.
“You crazy bastard! There are things you can and cannot say to your own sister!”
“I-I’m sorry. I admit this one for real.”
“It’s not just this one you should admit. Fuck. At this point you’re comprehensively beyond saving. Just die already. Go kill yourself!”
It whistled terrifyingly through the air. No joke—if it actually hit me, I’d be dead.
“I’ll head out first! Wash up and come out soon!”
In the end, I fled while still dripping wet. I told her to come out a little later. Once she’d calmed down at least enough not to kill her brother.
I grabbed one of the towels stacked in the living room and went into my room. I dried off quickly and changed clothes. Just in case I needed to bolt out of the house.
‘Has Yunseo come out yet?’
I poked my head out and, right on cue, she stepped out of the bathroom.
“.......”
“D-did you finish washing?”
The look on her face as she stared at me was ominous. Maybe I should have just let her hit me until her anger subsided earlier. No. I probably would have ended up in the hospital.
“Minjun.”
“Yes, Sis.”
“I really... my feelings toward you keep swinging back and forth.”
“Huh? Why? I only ever think about you with single-minded devotion.”
“....... Whether I should kill you or not. I was seriously considering it just now.”
“But since there’s nothing in your hands, it looks like reason won in the end? Your love for your brother. Good job. Well done, Sis.”
“That’s not it.”
“No....... Hey? Huh? That can’t be right. My kind sister wouldn’t do that.”
“I was thinking about how to torment you as painfully as possible.”
“Uhhhh. Sis. Just thinking, okay? Just thinking. I really won’t act up anymore.”
I quickly ran back to the living room, grabbed a towel, and began drying her hair as carefully as I could.
“Should I flick your balls every time you act up from now on? Or pull out a clump of your pubic hair? Stabbing it with a needle would work too.”
“Do you have plans to send your brother to the grave? Those torture methods are brutal.”
“It’s not torture, it’s the whip of love. The whip of love meant to turn my idiot brother into a proper person.”
“If my old-fashioned way of expressing affection has offended you....... I sincerely apologize. But still, fuck. There’s a limit, you know. A limit.”
“Minjun.”
Her voice was ice-cold. I shut my mouth immediately.
“....... Yes.”
“Could you say the same things you said to me in front of Mom and Dad?”
“....... No.”
Things like our pussy and cock meeting. Making my sister bleed too. Making a baby.
“Then how the fuck is that normal affection?”
“If it made you uncomfortable, I truly....... am sorry.......”
“Let’s do better. Okay?”
“Yes. But some of the things you said aren’t appropriate in front of our parents either. If you tell them you’re going to flick your brother’s balls, they’ll disown us immediately. Siblings becoming strangers and all that.”
“....... Are you going to keep talking?”
“No.”
After drying most of the moisture from her hair, I wrapped my arms around her.
“The hair dryer’s in your room, right?”
“Yeah.”
“Then let’s go there.”
“I can walk on my own.”
“Come on. I’ll serve you comfortably today.”
I found the hair dryer, plugged it in, and turned it on cool. I ruffled her hair as I dried it.
“Your customer has such lovely hair.”
“.......”
“This level of compliment is okay, right? Surely this doesn’t bother you? Or tell me what level is acceptable.”
“Think about how Mom and Dad would feel if they heard you. Do I really have to teach you this? How old are you?”
“But if I said I love you in front of our parents....... they’d probably faint, right?”
“....... Then use your own judgment. Say things that seem like they’d be fine.”
“Saying you’re pretty is okay?”
“....... Yeah.”
“What about lovely? Cute?”
“I don’t know.”
“If you don’t know, who would?”
I gave her a quick peck on the cheek.
“What about this?”
She glanced at me. I couldn’t tell if she was angry or not.
This time I kissed her lips. She glared at me again.
‘Then what am I supposed to do?’
I went back to drying her hair. With how thick it was, it would take a while.
“Kissing isn’t allowed either.”
It was embarrassing to say, but we had sucked each other’s genitals before.
“....... If you’re going to do it, do it properly. Don’t treat it like a joke.”
“After I finish drying your hair.”
“Exclude all that fucking sexual harassment. One flick to the balls for every syllable.”
“That would leave bruises.”
“Then just don’t do it. If you don’t, you won’t get hit.”
“It’s become a habit, so.......”
“It’ll be fixed after a few hits, won’t it?”
“A few hits and a man would die. Are you going to flick a corpse’s balls?”
The conversation between siblings was truly heartwarming. I didn’t know what family they belonged to, but one thing was crystal clear. The pair who stopped drying hair just to kiss each other were far from normal. And despite claiming they were busy and had somewhere to go, they ended up collapsing onto the bed together once again.
