Mapping Her Body with My Hands
I kissed my sister while letting my hands roam all over her body. I wanted to figure out exactly where she hated being touched and where she liked it. It felt like solving a puzzle. Whenever my hands drifted toward her chest or stomach, she’d growl like she was ready to devour me. But when I stroked her hair, she’d go all quiet and docile. The moment I traced little hearts on her back in slow circles, she didn’t say a word, but her hips started twitching.
“Haa… haa…”
When I finally pulled my lips away, her breathing was ragged.
“Were you holding your breath?”
“……No.”
“Then it looks like you need more practice. We’re going to have to do kiss training every single day from now on.”
“Who said you get to decide that?”
“I did.”
“Fuck off.”
“If you don’t want to, just dodge my lips.”
“………”
“Sis.”
“Hey! Where the hell do you think you’re putting your hand?”
I slowly slid my fingers under the hem of her shirt and began stroking her bare back. The second my palm touched her skin, she snapped at me. If I try to undo her hook, she’ll probably kill me. But at least she wasn’t throwing punches yet.
“Hey. What exactly are we to each other?”
I asked while peppering soft kisses along her ear and the nape of her neck to calm her down. My fingers kept drawing endless hearts on her back.
“What are we?”
“Let’s be honest. We’re not exactly a normal brother and sister anymore.”
“……A sexual assaulter and his victim.”
“Not that.”
“You’re literally grinding your dick against me right now and you’re still saying ‘not that’?”
That’s rich coming from you. Who was the one who just rubbed her ass against my crotch?
“Saying we’re just close siblings feels… like we’ve both gone way too far for that.”
“Then we can just go back to how things were.”
“I don’t want that.”
My hand that had been on her back slid down to her waist.
“So what? You want to fuck me so badly it’ll finally clear your head?”
“I never said it that bluntly.”
“Then… what do you want from me?”
“Hmm.”
I gave her ass a gentle pat. She let me touch her over her pants, but the second my hand slipped inside her panties, I knew she’d grab me like she was trying to catch a rat.
“Sis.”
“What? Again?”
“Can’t we… just date until you finish your novel?”
“What?”
“Just until it’s completed. Honestly, there’s no going back to how we used to be. You know that too.”
“………”
We had shown each other our bodies. We had touched each other’s genitals. She had even taken my cum on her face. Her little brother had confessed his love to her, and right now he was kissing her while rubbing his swollen cock against her.
“If it’s too hard to answer right now, you can tell me later.”
“No, um… I’m just really surprised.”
“I confess my love to you every day. I keep telling you I like you.”
“Still, that’s different from actually dating. If we date, then… then…”
“Then?”
“We’d probably have to… do that too.”
“Sex?”
“Can you not say it so crudely! Are you really going to go around telling people you’re going to stick your dick in your sister’s pussy?”
“I don’t say it that openly either.”
“Anyway! It’s completely different from what we’re doing now. This would be crossing the line with full intention.”
“We’ve already crossed it… we just haven’t said it out loud… Hey, honestly, what kind of sister asks her brother to show her his dick?”
“You fucking asked to see my tits too.”
“Give and take, that’s how it works.”
“So helping with your novel was all just an excuse, huh?”
“I’ll always help with your novel. I can help right now too. The protagonist should be touching the heroine’s breasts around this point, right? Want me to touch them for you right now?”
“You just showed me your dick, you idiot. Don’t just make shit up.”
“If you show a guy your dick, of course the heroine’s going to do something with it. Whether she sucks it, bites it, or strokes it.”
“……I’m going to write a scene where she does it with her mouth, just like we did.”
“Then let’s write it right now. Keep talking. I’ll type.”
We both turned back toward the laptop again. Of course, we stayed glued together in the same chair. There was no real reason to sit separately, after all.
“The younger brother’s cock was enormous.”
Tap. Tap. The keyboard clacked.
“As a virgin, I was terrified whether I could even take something like that inside me.”
“Sis. Don’t just sit there. You have to do your part too.”
“H-how?”
“Put it in your mouth.”
“Th-this big thing… it won’t fit…”
“Then take it down below. You’re going to have my babies eventually anyway. Think of it as a rehearsal.”
“Please… Master.”
“Your virginity belongs to me. Whether I take it now or later, it’s all up to your owner, isn’t it?”
Gulp.
“I-I understand. I’ll do it with my mouth.”
“She pressed her lips against the head of her brother’s cock. Sis, open your mouth wider. That’s it.”
“It was so big. The moment she took his cock into her mouth, she felt like she couldn’t breathe.”
“Mmph, mmph. Sis, move your hand too. Do I really have to command you on every single thing? And stop writing ‘hii’ at the end of sentences, it’s supposed to be ‘huh’ or ‘haa’.”
“Ah, sorry.”
“You’ll get red underlines if you make typos. You wanna die?”
I scolded her nonstop while fixing all the typos.
“Saliva dripped down the length of her brother’s cock. Swallow it all. Understood, Master.”
“Her brother is a total piece of trash.”
“Like you?”
“Nah, I’m not that bad.”
“Take it off.”
“Huh? Even my panties? You need your dick out?”
“No, you idiot. It’s for the novel.”
“O-okay.”
Tap tap. The keyboard started again.
“She asked her brother in return.”
“You’ve sinned against your Master, so you must pay the price. Take everything off.”
Looking at this novel… it feels like Sis modeled the heroine after me and the brother after herself… It’s basically our sibling dynamic but gender-swapped. The kind, gentle older sister is me, and the younger brother who’s dying to devour her is Sis.
“With trembling hands, I pulled my t-shirt up. My brother stared intently at my breasts.”
“You have to take it all off, Sis. Lower the straps and undo the hook. Your nipples look so delicious. His lewd hand finally touched them. Haa, haaht. The moment he pinched my nipple, a shiver of pleasure ran down my spine. Without realizing it, I started rubbing my thighs together.”
“……Must be nice. Getting to touch your sister’s tits.”
“What?”
“Ah, never mind. Sorry. I got jealous without thinking.”
“Ugh, seriously. You’re ruining my concentration, you pervert. Just touch your own. Yours are bigger than mine anyway.”
“Aww, but it feels different! Look. Ack!”
The second I stroked her stomach, she pinched my thigh hard.
“Stop messing around and keep your hands on the keyboard.”
“Sob sob. You’re so mean.”
“You’re the one who’s mean. You’re supposed to be thinking about the novel, not worrying about getting raped by your brother.”
“If I really wanted to fuck you, I would’ve done it already. If I followed my instincts, we’d already have three kids by now.”
“Keep saying stupid shit and I’ll kick you out.”
“Yes ma’am.”
“Sis, do you like it that much when I touch you? Her brother smiled at her.”
“I had to take everything off. What if I upset him again? I was worried. If he got angry at me for being wet again, if he decided to take my virginity as punishment…”
“Down below, I was getting wetter and wetter. I was going to offer my purity to my brother. He was going to ravish me.”
“Finally. At last.”
“I took off everything I was wearing below in front of my brother. As I slid my panties down, a transparent string of my juices stretched out.”
“S-Sis.”
“What now?”
“Let’s take a break for a second. I can’t hold it anymore. My dick feels like it’s going to explode.”
“You don’t have to narrate that part, you idiot.”
“You really are a genius at both looking hot and writing hot shit.”
My pants were tented so hard it looked like they might rip.
“Where are you going?”
“Huh? To my room.”
“……You can do it here.”
“How am I supposed to do it in front of you?”
“You already came all over my face.”
“That’s… plus, I usually need visual material rather than just imagination.”
“What? Porn?”
“……Yeah.”
“At this rate, you’d probably finish if I just touched it a little.”
“No I wouldn’t.”
“Just do it.”
“Then at least give me some tissues. Wait, hold on, you crazy bitch. Why the hell do I have to jerk off in front of you? Now that I think about it, this is weird.”
“……It’s for my novel.”
“I already showed you once. Half willingly, half unwillingly.”
“It was 100% unwillingly. You’re the one who came in two seconds like a premature ejaculator. Anyway, you get hard the second you see me. Let’s help each other out.”
“What do I get out of jerking off while looking at you? It just makes me feel like shit.”
“……I’ll let you touch me a little while you do it.”
“Really?”
“You look way too happy for an idiot.”
“So, over the panties or under? Should I wash my hands first?”
“You piece of trash, I was talking about my breasts. Forget it. Just go. Go to your room, watch porn, jerk off, do whatever you want.”
“I’m sorry. I’m so sorry.”
I begged again, practically on my knees.
“……You’re such an idiot.”
Sis took off her t-shirt. Why on earth was she showing me this kind of mercy? Had this troublemaker finally reached enlightenment? Or maybe…
Of course. You’re horny too, aren’t you?
Even while writing her erotic novel, she kept subtly rubbing her crotch against my dick. She probably thought she was being sneaky, but the heat was unmistakable. The space between her ass and her pussy was burning up.
Dear ancestors, thank you for blessing me with a huge cock. From now on, I’ll offer foreign liquor instead of soju at your memorial rites.
“Can I try undoing the hook myself?”
“……Do whatever you want.”
I fumbled around. This was harder than it looked.
“How do you do this?”
“Push both sides together. Then pull the side with the hook. Yeah, like that.”
Click. As soon as I followed her instructions, the bra came loose and her breasts spilled out.
“No matter how many times I see them, they’re so beautiful.”
“……You saw them yesterday too. You ripped it off me.”
I had no idea how our memories were being stored in her head. Rape, pornography, erotic novels. Looking at the filters she always used, it seemed like she was even hornier than I was.
“You can’t show these to anyone else, okay? Your breasts are mine for life.”
“I won’t show them. Idiot. There’s no one I want to show them to anyway.”
“What about me? Me.”
“You’re not a person, you beast.”
“Woof woof. Is that good enough, Master?”
“Ugh, fucking disgusting.”
I slowly placed my hand on her breast. My heart was pounding like crazy.
How should I touch her so she’ll like it? Should I pinch her nipple? Or tickle around her areola in circles?
“You only get one minute, so hurry up.”
“Hey, what kind of rule is that? At least give me ten minutes.”
“……I’m just trying to know what it feels like when someone else touches them. I don’t need that long.”
“But I need at least that long to get off while touching you. It already took me a whole minute just to take my dick out.”
“That’s your problem, idiot. You’re a quick shot anyway, so just cum quickly.”
This bitch…?
Fine. Prepare yourself.
“Then I’ll use my tongue.”
“What? Hey… wait!”
Before she could protest, I buried my face in her chest.
“You son of a, son of a, son of a bitch! Haaht! Hey! No, mmh!”
I took her entire breast into my mouth and sucked hard on her nipple.
“S-stop it. Haa, haaht. Mmm…”
Her aroused moans kept ringing right beside my ear. At this point, even if it meant getting beaten to death, I was going to keep tormenting her breasts.
