Gulp. Swallowing Hard
Gulp. I kept swallowing, over and over. Of course, it couldn’t be as bad for me as it was for my sister, who had to show every inch of herself to her little brother… Still. The nerves were impossible to shake. My entire body had gone rigid.
My sister’s pussy. My sister’s ass. The last time I’d seen them was back when we were so young I could barely remember it—bathtime together. We were both completely different now. My sister’s breasts had swelled, her hips had widened, her ass had filled out, her waist had narrowed. She gave off a sweet scent, her mouth was as foul as ever, but her voice had turned seductive. The place she was about to show me would probably have hair by now. Which meant she could get pregnant now… And. And.
With trembling hands, my sister slid her panties down to her thighs.
“D-does it look weird?”
Slowly. I stepped closer. I wanted a better view. I wanted to examine my sister’s most precious spot in detail.
“It’s pretty. It’s so pretty, sis.”
Sticky arousal glistened under the bathroom lights.
“R-really? You’re not just saying that… it’s pretty?”
The sight of my sister’s body after so long filled me with something close to reverence.
“It’s beautiful. How did you grow up this beautifully… Our sister really turned out perfect.”
Her pussy stayed neatly sealed in a lovely line, but every time she exhaled, a trickle of clear fluid leaked out. I wanted to push my tongue inside and drink every drop. Forever.
“…There’s not a single hair. Did you shave it so your brother could get a good look?”
“…It’s always been bare, you idiot.”
“That’s perfect. It would’ve been a crime to hide a pussy this pretty.”
“Instead of just saying it’s pretty, be specific. Where? How?”
When I breathed in, a sharp, musky scent rose. The smell of a female in heat. I focused between her legs. Past that entrance must be her hymen. Deeper still—her eggs, her womb. The space where our baby would grow if we ever mated.
“The way your pussy closes up so neatly? It looks plump. I bet it would wrap around a cock and feel incredible.”
“…Fuck. I asked you to describe how it’s pretty, not sexually harass me.”
“That’s what happens when you stare at pussy. The color peeking out between the lips is a gorgeous pink, too.”
“Hey—s-stop coming closer. And stop breathing on it.”
“I’d die if I stopped breathing.”
I moved in until my face was nearly touching her.
“…Touching is absolutely not allowed. Looking only.”
“I know.”
“It… doesn’t smell bad, right?”
“Nah.”
“R-really? Not like piss?”
“No. It smells like a really horny female. What, did you piss and forget to wipe?”
“No, you idiot.”
“Then why are you worried?”
“…Because you keep sniffing like a dog. I got nervous.”
“Aigoo, our cute Yunseo. Even your worrying makes me want to fuck you like a bitch in heat.”
“Hah—hngh! Hey! What are you doing!”
“I never said I wouldn’t touch your ass.”
I grabbed her ass with both hands and kneaded it firmly.
“When are we actually showering? The tub’s already… full.”
“We’ll take our time. The water’s too hot anyway. We’d burn ourselves if we got in now.”
“Perverted bastard.”
“I’m only a pervert for you, sis. Seriously, how did Mom manage to birth a daughter this gorgeous?”
While massaging her ass, I subtly spread the cheeks apart. I want to see this part too.
My sister immediately smacked my forehead with her palm. If I asked her to turn around, she’d probably kill me.
“This is why a little brother can’t help falling in love with his sister. Such a cute girl. Such a beautiful woman.”
“…Fuck. Stop buttering me up. I’m still not letting you put it in.”
“Today I’m satisfied with just looking.”
“Not just today—tomorrow, the day after! You idiot, you’re never getting inside me.”
“Whatever you say.”
The hands kneading her ass slowly drifted lower.
“Hah, hngh! Hey! Where do you think you’re touching?”
“Isn’t that part of your ass too?”
“You fucking—does your ass have a pussy attached?”
“I don’t know female anatomy that well.”
“Are you going to keep bullshitting? I’m standing here completely naked in front of you.”
“Sis.”
“…What.”
“You asked me earlier how I masturbate, remember?”
“…Yeah.”
“You said you spread it open with both hands? Like this?”
“Fuck off. You… don’t need to know.”
“Can’t you teach your little brother when he’s curious?”
“You crazy bastard. How am I supposed to explain that?”
“Why not? Just show me.”
“Fuck. You want me to finger myself in front of you?”
“You said you’d spread it and only touch the outside. Not finger it.”
“You remember that shit perfectly, like the pervert you are.”
“The more I imagine your body, the hornier I get. By the way, your pussy is way prettier than I imagined. Seeing really is believing. It’s better to see your pussy once than hear about it a hundred times.”
“…Thanks for the compliment, you crazy fuck.”
“Especially that pink that keeps flashing. Inside must be completely pink too, right? Strawberry flavor? Or peach?”
“What do you want me to do about it, fuck. Just imagine from the outside like you said.”
“Since we’ve gone this far, you might as well show me the rest. Come on, open up.”
“Are you going to keep pushing? And why aren’t you jerking off? Weren’t you going on about holding back earlier?”
“My arm’s getting tired. And I was wondering if I really have to put up with all this verbal abuse just to keep from raping you. It’d be easier to just make you suck me off.”
“I have zero intention of putting your smelly cock in my mouth.”
“Then I’ll put it in your pussy. You did say you wanted to be raped.”
“You son of a bitch! Who said that?”
“I did~”
“Hah—hngh. Haa. Hee. D-don’t touch. You can’t touch me there.”
“I was just wiping the juices off your thighs.”
“I t-told you not there. Haa. Hoo.”
Slowly, I used both fingers to pinch the flesh beside her pussy, spreading and closing it. Her hole winked open and shut in response. The slick sounds of her arousal being rubbed filled the air.
“S-stop messing around. This is weird. This is really weird.”
“You suck mine and I’ll suck yours. They do it all the time in porn. Let’s try it.”
“Haa, haa, I said no… Haa.”
“Come on, sis. If you’re going to refuse, at least make it convincing. Your pussy’s dripping wet, your nipples are rock hard, and you expect me to believe you when you say no? What a pathetic little cunt.”
“T-this is just a physiological reaction. Haa, haa. Even if a bastard like you touches me, I can’t help it—haa. Haa.”
“Then let me help a little with that physiological reaction. Your lust. Your desire. Let me lick it just a bit.”
“At least shower first before you put your tongue—ahk! Hngh!”
I gripped her ass so she couldn’t escape and buried my face between her legs.
“Mom—haa! I’m becoming weird. I’m getting raped by my brother, haa! Ungh, haa! Haa. Save me.”
I tensed the tip of my tongue and pushed into her pussy. Not too deep—I didn’t want to hurt her hymen—so I focused on the outer folds. Lick. Lick.
Leaning against the bathroom wall like she was melting, my sister bucked her hips. Her legs spread wider and wider toward me until her stance completely collapsed.
Sweet. As expected. My sister tasted delicious. The best thing Mom ever created. Slightly salty and musky, maybe from sweat. An addictive, lovely flavor. Every time I licked here and prodded there, my sister kept feeding me her sweet nectar.
This is the labia minora. And this bump catching on my tongue is her clit.
“Haa. Hngh. Hic. Haa! Hoooo! Haa. Please. Slowly. Please go slower.”
Every time I flicked my tongue, her waist jerked violently.
“Please. You’ve already licked my pussy so much. Please. Hoo, save me. It feels weird. Haa!”
She could barely stand anymore. She clung to my shoulders to stay upright.
“Ah—a baby’s going to come out. My pussy feels weird, I’m—I’m coming! I’m coming! You son of a bitch! My pussy feels so weird! I’m coming!”
She cums so dramatically.
In the end, her whole body trembled and folded.
“Whoa, sis. You’ll hurt yourself.”
I quickly stood and caught her. She might crack her head open like that.
“Haa. Haa. Haa. Haa.”
My sister finally collapsed to the floor, panting. Her face was completely melted. She couldn’t even focus her eyes.
“It must’ve felt really good.”
“Haa, haa. You fucking… fucker…”
“Felt so good you came like a bitch?”
“You son of a bitch. How many times did I tell you to stop—haa. I told you over and over. But you never listen.”
“I thought it was some kind of cheer. You were enjoying it so much.”
“Now it’s your turn. Fuck. I’m going to suck your cock until it snaps off.”
Suddenly she grabbed me. Now it was my sister’s turn to take me into her mouth.
“You can go slow.”
“Shut up.”
“Lick it with your tongue, sis.”
“Shlurp. Mmph.”
“What? You love me?”
Chup. Chup. My sister stuffed my entire cock into her mouth and sucked hard. Juices poured down between her own legs. Saliva dripped from the corners of her lips.
“Yeah, what goes around comes around. You came so hard earlier.”
“…Chup. Chup. Lick, haa, lick. Your cock—fuck. It’s stupidly huge.”
“Why complain when it’s big? Hurry up and suck properly. We still need to shower and get in the tub.”
“Son of a bitch. You said it was fine when I was licking you.”
“Guess hypocrisy is our sibling specialty. Wait—licking you? Licking your pussy?”
“Fuck. You idiot. Hey! Don’t touch!”
“Your pussy’s right here. Anyway, finish sucking. My dick’s getting cold. It wants to go somewhere warm.”
“…Son of a bitch. Chup. Chup.”
“Stop kissing the head. It just tickles.”
“Want me to grab a cucumber and shove it down your throat? See how it feels? It’s too big… it’s hitting my throat.”
“Then just suck the front. Hngh, wait a second.”
The moment I finished speaking, her tongue slid along the underside of my shaft like she was trying to pierce it.
“Whoa. As expected. Teach my sister one thing and she wants to learn ten. You’re really going for it.”
Drip. Drip. All kinds of fluids fell from my sister’s body onto the floor.
“You’re the literal incarnation of horniness. Fuck.”
“Do you like me that much?”
“Yeah.”
“How much?”
“Enough to get hard just picturing your face. Enough to devour three bowls of rice just from smelling your pussy.”
“Seriously. Perverted bastard.”
She’s not going wild this time. I’d been a little tense, wondering if she’d start thrashing while sucking me again, but she was quietly servicing me.
“Uh, uh, sis. You don’t have to do that part.”
Apparently she did. Speak of the devil. Her tongue kept tapping my balls.
“Why? Scared?”
She shook my cock and kept popping just the head in and out of her mouth. Whew. If she kept this up I wouldn’t be able to stay calm.
“Yes. Quite a lot.”
“If I bite down hard right here, you won’t be able to act up anymore, right?”
“T-that would mean I’d have no way left to love my sister. Whoa, spit it out, good girl.”
“Why? You licked my pussy everywhere you wanted. Stay still.”
“Haa. Haa. Sis. Y-you really don’t have to. Ohh.”
It felt like getting a razor shave down there. One slip and it was over.
“…The hair tickles.”
“Sh-should I shave it?”
“No. With a cock this big, it’d look weirder without any hair.”
Thank god. She was letting go. Wait—no? If she kept going I’d have no choice but to smack her.
“Ah, your expression. It’s hilarious. A guy as big as a mountain trembling every time his balls get touched.”
Even through all the torment, the signal was finally coming.
“S-sis. I’m about to…”
“When the cum comes out, how about here? If I keep sucking, will you feel it?”
She cupped my balls. Then she took the entire head into her mouth.
“It’s… coming. You should stop now.”
“……”
If she kept going I was going to cum in her mouth. Ignoring me completely, my sister continued sucking my cock.
“Sis. I’m serious, I’m cumming.”
Why was she like this? I had no interest in blowing my load in my sister’s mouth. I wouldn’t want to eat my own cum either. Still, she kept sucking. I couldn’t hold it anymore. From deep inside my body, the slow surge of pleasure began to rise. Straight toward my sister’s mouth. Straight toward her throat.
