Brushing Her Teeth
I finished class as usual and was on my way home when I spotted a takoyaki truck parked out front. I pulled out my phone and texted my sister.
[Sis]
[Want some takoyaki if I grab some?]
Her reply came almost instantly, like lightning.
[ㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱ]
[ㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱ]
[ㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱㄱ]
What the hell is wrong with her again…? I let out a small chuckle and typed back.
[You really want it that bad?]
This time she sent a sobbing emoji along with her reply.
[I worked out today]
[I'm starving T_T]
[Okay]
[Yesss haha]
I slipped my phone back into my pocket with a grin and walked over to the truck.
“Two orders of takoyaki, please.”
A short while later, I was carrying a black plastic bag filled with the steaming snacks as I headed to my sister’s place.
Just like last time, she was sprawled flat on the bed like she’d become one with it. At least today she seemed to be in better shape—she’d actually taken her panties off properly.
The moment she caught the smell of the takoyaki, her eyes lit up and she sprang upright.
“Oh yeah!!! Welcome back, big bro!!”
“What the—weren’t you half-dead a second ago? Why are you suddenly so energetic? You really wanted this that much?”
“Hehe, yup! Gimme, gimme, gimme…”
I teased her by holding the bag just out of reach. She drooled shamelessly and kept swiping at it with her hands.
Then, apparently reaching her limit, her face suddenly twisted into a ferocious scowl and she snapped.
“Ughhh, stop messing around and hand it over already! I feel like I’m gonna die of hunger!”
“Pfft, alright, alright. Here.”
The second I set the bag down, she pounced on it like a starving wild dog, yanking out a piece with a toothpick and shoving it into her mouth.
“Hoo… hoooh… it’s, it’s so hot… w-water…”
“Aish, that’s why I told you to eat slowly. What are you even doing…”
I clicked my tongue in exasperation and grabbed a cold bottle of water from the fridge. She pressed her lips to the two-liter jug and gulped it down greedily.
“Khaaa! Haa… my tongue… it’s completely burned black… look at this, Namhyuk.”
She stuck out her long tongue, still steaming, and showed it to me.
The sight of her pink tongue instantly brought back the memory of our kiss the other day. My face flushed and I quickly turned away, pretending to be annoyed.
“Ugh, why are you showing me something so gross… Just finish eating.”
“Hehe, you should eat too, Namhyuk. If you don’t, I’ll eat it all myself.”
I sat across from her with a smile and we ate the takoyaki together. After burning herself once, she started poking holes in each piece, blowing on it carefully to cool it down before eating.
…She’s eating even better than usual today. It’s nice to watch. I feel like I’m feeding a hungry hamster. It makes me feel good.
When we were about halfway through, she spoke while still chewing vigorously.
“Namhyuk, the club president asked me to go to Gangnam with her tomorrow evening.”
“Huh? Gangnam? For dinner?”
“Nope. We’re going to a massage shop! She was originally going with a friend, but she said she’d take me too. Hehe… She’s seriously so nice.”
…That president person. She only met my sister a few days ago, yet they’re already so close. It’s amazing that someone can get along with a weirdo like her so well…
Then again, outside the house my sister just looks like a bit of a loner. She manages to act relatively normal in public.
If I hadn’t met her at home first, I never would’ve guessed she lived like this.
As I stared at her in silence, she narrowed her eyes and grumbled.
“…Hey? Why are you looking at me like that? It’s like you’re suspicious that someone as pathetic as me could make a friend so quickly…”
“Hmm, you caught me…? Yeah, I guess it was pretty obvious.”
She puffed her cheeks in frustration, glared at me, then popped the rest of the takoyaki in her hand into her mouth. She flopped backward onto the bed and lay spread-eagle while still chewing.
“…Hmph. If I actually tried, I could make friends whenever I wanted. I just haven’t felt like it until now. Anyway.”
“Yeah, yeah, sure you could. You don’t want any more takoyaki?”
“Nope. I’m completely full now. Hehe…”
Still lying on the bed, she rubbed her belly with a blissful expression. I chuckled softly and slowly finished off the rest.
“Namhyuk~ Look over here. Hehe.”
Now that her stomach was full, her voice had turned lazy and sleepy. Then, without warning, she suddenly thrust her hand out toward me, pointing sharply.
“…W-what?”
I looked back and forth between her and her hand with a nervous expression. All of a sudden her eyes sparkled and she shouted.
“Surprise attack! Rock-paper-scissors—wait, no! Look this way!”
“W-wait…!”
Caught off guard, I reflexively turned my head in the direction she was pointing.
Ah… I let my guard down. How could I fall for something like this…
While I clutched my head in shame, she danced around in delight, her voice bubbling with excitement.
“Yes!! Hehe, I totally got you, didn’t I? You fell for it so hard! Kyahaha, Namhyuk, you’re seriously so cute!!”
“Ugh…”
…Damn it, why does today feel even more stressful than usual…? Falling for such an obvious trick…
Because this time I really had been tricked instead of just letting her win, the humiliation hit me harder than normal.
As I bit my lip with a sullen expression, she quickly ran over to her notebook and drew another heart. Then she squatted down, giggling, and shouted at me.
“Seven wins♥!”
I glared at her as she basked in her victory and grumbled.
“…So what’s your wish today? Hurry up and tell me so we can get it over with.”
She immediately scrambled over, dropped to her knees in front of me, sat politely, closed her eyes tightly, and opened her mouth wide.
I was once again thrown off by her ridiculous behavior, even though I should’ve been used to it by now. I asked with a sigh.
“…What are you doing? Why did you suddenly open your mouth so wide…?”
“Hehe, today’s wish is this. It’s too much work, so you brush my teeth for me~~”
“What…? What are you talking about? Does it even make sense to ask someone else to brush your teeth…?”
“Yup, it does~ Hehe. Hurry up~~”
She shoved me toward the bathroom with both hands. I couldn’t hide my bewilderment as I reluctantly went in, put toothpaste on her toothbrush, and brought it back.
Seeing the toothbrush, she gave me a mischievous grin, then knelt again, opened her mouth wide, and gently closed her eyes—just like before.
I stood in front of her holding the toothbrush, hesitating for a long time. It wasn’t just that the situation was absurd; something strangely erotic kept flashing through my mind.
…Hmm… This angle feels weirdly familiar… I feel like I’ve seen it in some inappropriate places…
“Ah, what are you doing! My mouth is filling with saliva, hurry up!”
“…You’re not a kindergartener. Aren’t you embarrassed to make someone do this?”
“Hehe, nope, not embarrassed at all~ Hurry~~”
…She was sitting right in front of my crotch with her mouth wide open, looking as innocent as a baby bird waiting to be fed.
From this angle, I could see straight into her open mouth. Every glistening strand of saliva, the little uvula at the back—everything.
On top of that, her beautiful features as she looked up at me with gently closed eyes, the smooth curve of her cleavage below, and the completely bare lower half beneath that… The whole sight nearly made me lose control again, just like last time.
No. Calm down… I’m not a kid. I can’t lose it over something like this…
Okay. Focus on brushing. Focus… But how exactly do you brush someone else’s teeth? I’ve never done this in my entire life…
I carefully brought the trembling toothbrush toward her open mouth.
I slowly pressed the bristles against her teeth and moved it in and out. Suddenly, she closed her lips around the toothbrush.
Then she looked up at me with playful, sparkling eyes, giggling as if urging me to keep going. I couldn’t look at her directly. Blushing furiously, I kept sliding the toothbrush in and out of her mouth.
Brush, brush, brush, brush, brush…
As the toothbrush cleaned her molars, her cheeks puffed out like a squirrel’s, then deflated, over and over. When I moved to her front teeth, she turned her head side to side, following the motion of the brush.
Eventually, she seemed dissatisfied with my timid brushing. She frowned, looked up at me, and mumbled around the toothbrush.
“Hey! Do it properly! You’re not even brushing anything right now!”
Then, growing impatient, she started moving her own head back and forth, forcing the toothbrush deep into her throat and pulling it out again.
“Slurp, slurp, shlorp…”
…Wait, that’s not okay…! My control…!
Finally, right in front of her face, I couldn’t hold back anymore. Just before I completely lost it, I yanked the toothbrush out and shouted urgently.
“I-it’s done, right? Go spit it out…!”
“Mmph…!”
Because I’d suddenly let go, thick white foam poured from the corner of her mouth, dribbling down her chin and pooling heavily between her breasts.
…Ah…
The moment I saw that, I finally lost control.
“Ugh, what are you doing…! It’s all dripping now…!”
She scowled and grumbled loudly, but then noticed me hunched over, silently turned away. She looked around in confusion and studied my face.
“…Are you sick, Namhyuk? Why are you acting like that all of a sudden…?”
“…My stomach suddenly hurts… Just go spit it out already.”
“O-okay…”
She kept glancing back at me worriedly as she walked to the bathroom.
I tried to calm myself while listening to her spit out the mouthwash, but every time I heard it, the image of her looking up at me with white foam spilling from her full mouth came rushing back. It took a full thirty minutes before I finally managed to calm down a little.
