The Burning Lesson
"So what are you going to do?"
"....... Can't you just explain it to me?"
"Explain what?"
"Like, whether it's hard or soft. You know your own thing best, don't you? You touch it every day."
Asking my own sister to rate my dick? That was one hell of an embarrassing request.
"I don't have a hobby of jerking off while savoring the details." Of course, there were times I admired it myself. Imagining how my sister would crawl on all fours at the sight of this size.
"....... You already gave me the panties. Just help without complaining."
"I already told you to do whatever you want. What more do you want me to do here?"
"Just tell me a little about the texture......."
"Hey. Just touch it yourself and judge. Am I the one writing the novel? You're the one writing it, right?"
"Ha....... Seriously."
"What? Last time you were so excited touching it. Asking if your little brother's dick got bigger or not."
"You idiot, that was over clothes. This is direct contact."
"It's fine. Here." I deliberately thrust it toward my sister as if showing off.
"Seeing it a hundred times is nothing compared to touching it once. You should stop complaining and just touch it."
She hesitated, inching closer little by little.
"Mom and Dad did it like this to have us, so hurry up."
"You crazy bastard, why are you bringing up Mom and Dad here?"
"Because you keep making a fuss. When a man and a woman love each other, touching and looking is just the natural order of things."
"Am I having sex with you right now? I'm just touching it there. And why would I love you......."
"Ah, you really talk too much."
Finally fed up, I grabbed both of her wrists. "Like this, hold it tight. Like this." Then I brought her hands to my dick.
Rub rub.
"Ugh, ugh. Ah. Hey. This is really hard. It feels gross."
"You said you'd let your little brother receive caresses from his sister. If you keep backing away like this, how are you going to write the novel? As a writer, you don't even want to do the legwork yourself. You have no fundamentals."
"It's disgusting! Look at the veins. Why is it so bumpy? And why is it so sticky?"
"I already told you it's because of you. It's like how your pussy gets wet."
"You perverted bastard, I told you not to say that!"
"Anyway, take it slow and do it properly. Stop huffing and puffing."
Both of my sister's hands came up over my cock. Clear fluid kept leaking from the tip of the glans that peeked out.
'Should I make her taste this too....... Wait, wait a second.'
But suddenly, "Aaaagh!" A pain like fire being set to my dick surged through me.
"Why, why. Why. Why are you like that? Don't tell me you're already c-cumming?"
"Hey. Move aside for a second. M-my dick is spicy."
I had forgotten that she had slathered her hands with pain relief cream. The smell had mostly faded so I'd forgotten about it. I should've bought the unscented kind if I knew this would happen.
I ran straight to the bathroom and splashed cold water all over it. Somebody save me.
"What's wrong? What the hell is going on? Should I call an ambulance?"
My flustered sister came running over too, stamping her feet.
"The c-cream. You put on the cream. On your hands. I think I'm going to go crazy."
"Oh my god....... What do we do? Does it hurt a lot?"
"It feels like hot sauce was rubbed on a pussy."
"What are you talking about, you don't even have a pussy. You're spouting nonsense, so it must not be that bad."
"Put yourself in my shoes, you fucking put yourself in my shoes! My dick is incredibly spicy. My dick!"
The thing that had been soaring without knowing the height of the sky finally bowed its head. 'I'm sorry....... Master.'
"Ugh......."
"If it's that bad, go to the ER. The doctors would be so shocked. They probably never expected some idiot who puts pain relief cream on his dick to show up."
"Blow on it."
"What, what the fuck?"
"Blow on it. It's because of you that this happened."
"You brought your hands over yourself. W-wait, why are you taking off your clothes?"
I threw off my t-shirt. It felt gross from the water.
My sister's gaze swept over my entire body.
"Because my clothes got all wet. Hurry up."
"....... It's calmed down now."
"Isn't that great? You wanted to see it from the beginning anyway."
"Yeah, I'm so grateful I could cry."
"Then stop crying and blow on it already. Wash your hands first. You set fire to your little brother's dick and you're trying to do that again."
"Y-yes. I'll fucking do whatever you say."
As I sat on the edge of the bathtub, my sister turned on the water at the sink.
'This won't do. I shouldn't look over there at all.'
Every time she rubbed her palms together, her breasts swayed along with them. If I looked at that, everything would be ruined. I wouldn't be able to show it again from the start.
"....... You should clean your dick too. Because I'm going to touch it from now on."
"Wait, then you should just wash it for me."
"W-why should I?"
"Because this happened because of you."
"I don't want to."
"You don't want to? You almost made your little brother impotent and you don't want to?"
"If we're being precise, this is all your fault. I really didn't want to touch it, but you forced me."
"I....... I did it all for my beloved sister....... Because you said your hands hurt. Because you said you needed help writing. Because you said you wanted to see your little brother's dick. Just for my sister......."
"Fine, fine. You're really making a scene."
Sniffle sniffle. My sulky expression worked on my sister.
"Then hurry up and wash your hands roughly and come over here."
"What, you weren't actually crying?"
"Why would I? When my pretty sister is going to touch my dick?"
"Can I scrub it with a scrubber? Your dick will sparkle."
"I told you to put yourself in my shoes. What would it feel like if I scrubbed your pussy with a scrubber?"
Her words were rough, but she obediently knelt between my legs. Squeeze squeeze. She squeezed body wash onto her palm and rubbed it.
"Don't do that, rub it on the hair here. It foams up nicely. Don't you do that?"
"....... Are you going to keep asking stupid questions?"
"This is the first time I asked."
"You have such disgusting hair growing there. From your navel down there, it's like a gorilla or something. Hey! Why is this like this again?"
"Because I was so excited thinking about you touching it......."
"Still, what the hell, it got this big again after just a short while?"
"Yes. Hey, Noona."
"What."
"Watching the process from before getting hard to getting hard is hard, but I can easily show you the opposite."
"How? Wait a second....... Don't tell me......."
"Yeah, exactly what you're thinking."
"No. Absolutely not."
"It's not like I'm asking you to put your pussy on it. Just that I'll cum. Then it'll go back to normal right away."
"Don't change the subject. You want to masturbate while looking at me, that's what it is."
"To put it precisely...... yeah?"
"Why do I have to watch you cum. It's disgusting."
"If Noona gives caresses in the novel, wouldn't the little brother naturally cum unless he's impotent?"
"....... Yeah."
"Then what are you going to say when that happens? If you don't even know how semen comes out of a dick?"
"....... I can just watch videos and write it."
"You really don't know anything, do you? In the first place, porn has a certain amount of lies in it. They pour fake semen and then edit to cover up the scene."
"....... How do you know so much."
"Because I've done a lot of research. Audiovisual education."
"Wow, what a great little brother I have. Thanks for showing off that your son-rearing is half a failure."
"Anyway, right now you're being too reserved. Hey, I'm starting to doubt if you even have the will to write as an author. Creation ultimately comes through experience......."
"Fine, fine, I get it, you fucking bastard. Stop talking and just point your dick straight."
My sister grabbed my thing firmly.
"This is what you wanted, right? Huh? You perverted bastard."
Every time she shook her hands up and down, bubbles foamed up.
"How is it? Good? You trash bastard? Because your sister is touching your dick? You filthy bastard."
Drip drip, the foamy bubbles fell toward the floor.
"Haa....... My arms hurt. Your dick is just stupidly big."
"Noona, if you do it like that, it'll never end even if you do it for a lifetime."
Finally unable to hold back, I said one thing.
"Right now there's no affection in what you're doing. Is this supposed to be caressing? You're just doing arm exercises."
"Isn't it enough that I'm not crushing the perverted bastard's dick that I hate?"
"No, that's absolutely not enough."
"Haa, fuck, then what do you want me to do."
"Mouth."
"Mouth?"
"Suck it."
"Are you fucking crazy? This is really. I've been holding back."
My sister slapped my dick away. It smacked down onto my thigh.
"What am I, a whore! You want me to suck your dick too!"
"Hey now, Noona. Calm down a little."
"Do you look like someone who can calm down? When my little brother is telling his sister to suck his dick!"
"If it were me, I'd be grateful. If Noona asked me to suck it."
"Yeah, you perverted bastard. I was wrong. I shouldn't have even asked for help from someone like you in the first place."
"No, why, Noona. How did it come to this conclusion. I was doing all this because I wanted to help you......."
"Is me putting my little brother's dick in my mouth helping? It's starting to get disgusting. That my brother is only this kind of man."
"Then what about the novel? You said the little brother makes his sister give him caresses. You said you wanted to write that."
"That....... with hands....... and mouth......."
"That's why. Try doing to me what the sister in the novel would do. Why do you keep interpreting my intentions strangely? I'm really doing this for you. Only for you."
"Swear on Mom and Dad?"
"Mom and Dad? Who are they?"
"I'm really going to erase you from the family register."
"Or if you don't want to receive it alone, I'll do it for you too. Just say the word. Mouth, hands, I can do it all day."
"Cut it out. Aaaaaah you bastard! Really....... Just this once?"
"I love you, Noona."
"Shut the fuck up. Do it properly even if you die. You see for yourself. Logically, how do you put this in your mouth."
"Or you can just put the glans in your mouth and stroke the bottom with your hand."
She turned on the shower and quickly rinsed off the bubbles.
"Would you want to make the woman you love do something like this."
"Because I love her, I want to make her do this. Because it's Noona's mouth. Because it's Noona's hands."
My sister stuck out her tongue slightly toward my dick. Tap. She touched the droplet hanging from the tip of the glans and quickly pulled her tongue back in.
"The taste is weird. It feels gross."
"Or should I put some jam or something on it? So you can enjoy it more pleasantly."
"You really only have perverted imaginations. You should be the writer."
"You can just write it in the novel too. Putting whipped cream on a dick and asking your sister to suck it."
"Are you going to keep making weird noises while using the novel as an excuse?"
"Let's just try putting it in a little. If it's too hard, you can just hold it in your mouth."
"Really....... I can't even bite it off."
My sister's pretty lips touched the glans. Then slowly, like a snake swallowing its prey, she took my dick into her mouth.
"....... How is it?"
"We just started, what are you saying. You need to move your hands or move your tongue or do something to get stimulation."
My sister tapped the gap between my glans with the tip of her tongue. Tap. Tap.
"Ugh. Haa."
A moan escaped me without realizing it. My waist twitched greatly.
When I looked down, my sister was looking at me as if she found it amusing.
"Hey, wait a second. There is too....... Don't do that."
Gradually, that devilish smile she always had when tormenting me appeared on my sister's face.
I almost fell backward so I quickly grabbed the bathtub.
"No, Noona. Don't just do there....... I said....... don't."
She seemed to have gotten the hang of it. My sister shook her head and moved her hands up and down. Between the glans. Under the glans. Without even being taught, she went after only my weak spots.
"Noona, Noona. Please....... Just a little slower....... Ahh!"
"Shut up."
My sister seemed to have taken a liking to playing with my dick. Of course, it felt good for me too. I was so happy that my sister was caressing me, but the problem was that the level of pleasure exceeded my imagination. Without realizing it, I kept making girlish moans.
"Hah. No....... This. It's too much more than I thought....... Noona......."
Slurp. My sister pulled my dick out of her mouth. Her hands were still moving up and down.
"Does it feel good? You trash bastard?"
"Y-yeah."
"Really. Your expression right now looks so pathetically stupid. I want to kill you. So doing it like this here feels good, right."
"A-ah."
She rubbed the gap between my glans with her fingernail. I couldn't move even though I was caught by a woman a head shorter than me, just holding part of my genitals.
"Go die, you bastard worse than a dog. Say it properly. You want to see my pussy so fucking badly right now, don't you?"
Some strange switch had been flipped.
"I'm not showing it to you, you bastard. Do you think I'm still a virgin trying to show it to someone like you. You idiot."
"Fuck, your dick is stupidly big. It's a waste to even use you as a dildo."
"You want to fuck me, don't you, idiot? I'll never give it to you. Just jerk off, you trash bastard!"
'Is she telling me to enjoy it quietly or not?'
She was still rubbing my dick while pouring out all kinds of curses, and I didn't know what rhythm to match. Whatever it was, gradually.
'I'm going to....... cum.'
The end was approaching. But if I just came like this, I was scared that my sister would completely flip out and twist my thing off.
"Y-yes....... I'm a trash bastard who wants to fuck his own sister."
Finally, I matched the rhythm, albeit clumsily.
"I'm an idiot who gets hard because my sister is so pretty."
"You bastard. Say it properly. How many times did you jerk off imagining fucking me?"
Slap. Slap. Slap. Slap.
"So many times. I came several times thinking of you yesterday and the day before too."
Slap. Slap. Slap. Slap.
"You fucking trash bastard. An idiot whose suicide would be filial piety."
"W-wait, Noona. Stop now, I really think I'm going to cum."
"What are you going to do about it, idiot. Don't give me orders."
"I said I'm going to cum, didn't I?"
"I told you not to fucking give me orders!"
"Hey, hey! Ugh....... No......."
Crash. Bang. Clatter.
"......."
"......."
Drip. Drip.
"I-I-I clearly said it, right? That this was my limit."
Semen was sprayed on my sister's face and chest. It flowed down her nipples and fell straight down below her.
It was an incredibly seductive and chillingly bewitching sight, but
"......."
"......"
I didn't have the leisure to enjoy this situation quietly.
"......."
My sister was still maintaining her silence. She looked around. I wiped the semen that had splattered on her body with the t-shirt I had thrown in the corner. On her nipples and stomach, lightly, lightly. Even when my hand touched her, my sister still didn't say anything.
"Well then, thank you for your hard work! I'll see you next time."
I quickly got up from the bathtub and bowed deeply to my sister in greeting.
"......."
Still, still, my sister didn't say anything.
What do I do now. What the hell.......
When I opened the door, "Kyaaaaah!"
My sister's scream was heard.
Pray, pray. At least I got one shot off, so that's a huge gain. Pray.
