The Mutual Bargain
“No…… It’s just…… I can use my own body as reference for the female parts, but I have no idea what a guy looks like down there.”
“That’s why I’ve been stuck. The story keeps going in circles because of this.”
“I really need to describe it now, but I’ve never actually seen one in real life.”
“I even watched porn and looked up pictures, but none of it helped at all.”
“Sorry for not saying anything and just…… sitting down. I thought if I sat on it for a second, I’d finally understand.”
Yunseo kept her head bowed, rambling in a flustered rush. All the while, her pretty ass remained firmly planted on my crotch, crushing it beneath her. I sat there in a daze, waiting for her to finish.
Show me. She was asking me to show her. It didn’t feel real. Had I hallucinated the whole thing? Maybe my feelings for her were so strong that my ears and brain had conjured up her voice on their own……
“Ah, ah, ah—stop poking me down there already. Seriously, tone it down. You’re gonna tear my clothes.”
Oh. Right. Yunseo lifted her hips slightly. The warm pressure that had been grinding so pleasantly against my lower half pulled away.
“That…… I mean, this is all so sudden. I don’t even know how I’m supposed to react.”
I’d almost pulled her right back down. Don’t move away.
“I already told you. Just show me what it looks like. For a second.”
“No, put yourself in my shoes. If you were me, how would you feel? Imagine I was writing a dirty story about eating my sister out, and I asked you to show me your pussy because I’ve never seen one before. Would you just sit there and take it?”
“……Money. Fine. I’ll give you allowance. If you help me with the writing.”
“Do you think I’m doing this because I need money?”
“Then what the hell do you want? You said you were my novel’s fan. This is why I can’t write the rest. Should I go find some pervert instead? Someone who actually wants to show it to me?”
“If there’s a bastard like that, I’ll hunt him down and kill him myself. How dare he even think about my sister.”
“Then you’re the only one left who can help. Please.”
“Haa. Yunseo. I do have some shame, you know?”
“That’s funny. You’re always telling me to get it up.”
“So when exactly have I been walking around with my dick out in front of you? This is…… completely different from just showing it.”
“Just a quick look. That’s all. I just want to see exactly what a guy looks like down there.”
Her face was bright red too. If I touched her cheek right now, I half-expected red paint to come off on my fingers.
“……Fine. Alright.”
“Really? You’ll actually show me?”
Yunseo’s expression lit up with pure joy. Is seeing her little brother’s dick really that exciting? Of course, it wouldn’t be free.
“Then you show me too.”
“What?”
“You show me. Don’t make a fuss about showing yours while refusing to let me show mine.”
Fair trade. If something’s given, something should be received in return. That’s the basics of any deal.
“A-Are you crazy? Why would I?”
“Oh please. It’s fine when you want to show it, but when I want to see, it’s suddenly insane?”
“Y-You’re a guy. I’m a girl.”
“What does that have to do with anything? A guy and a girl both dropping their pants is just a misdemeanor.”
“No. Absolutely not. Never.”
“Then I’m not showing you either.”
“……What about the novel? You’re the reason I can’t write it. Because you won’t help.”
“How is that my fault? You’re the one who won’t show me, so I won’t show you.”
“No matter what, that place is off-limits. When I say no, it means no. Stop making me repeat myself.”
Wait a second. ‘No matter what’? What did she mean by that? What exactly was I to her? The words lodged in my ears like thorns and kept spinning. What was I to Yunseo, really? Was touching her body okay? Kissing her? Could I even hope for anything more……?
“Besides, you already stole a look at my chest. We can call it even. I won’t complain.”
“Huh? When did I steal a look?”
“You wanna bullshit me? Until a second ago you were trying to yank my shirt all the way down. And your voice was disgustingly turned on. ‘Author Kang, Author Kang. Let me see your nipples, Author Kang.’”
“Got any proof? You gonna frame me? I was just massaging you because I was worried you’d be sore, and you let your perverted imagination run wild.”
In reality, I’d stared with everything I had.
“And even from above, nothing shows. How many layers are you wearing anyway? If you get a rash from sweat and have to go to the hospital, that’s all money too.”
“So you were trying to look. And you were wearing two layers, dumbass.”
I know. I’ve only been looking at Yunseo’s chest this whole time. Good thing my nose didn’t grow like Pinocchio’s when I lied.
“I didn’t see it, so I’m innocent. Thinking about stealing isn’t a crime. The crime only happens the moment you actually steal.”
“Your mouth is a fucking river. Anyway, you still tried to peek at my chest, you pervert! Why are you acting so proud when you got caught?”
“I said I didn’t see it! I didn’t see anything!”
In truth, I’d seen everything. It was a pretty pink. Because her skin was so fair, that place had been an incredibly clean, light color too.
“Whatever. I’m done talking to you. I’m quitting the novel.”
“Hey, why is it going like this? You have to keep writing. What about all your readers across the country?”
“I don’t know. Don’t talk to me. You’re pissing me off. They’re probably all perverts like you anyway. Wanting to read about real siblings fucking.”
You’re the one who wants to see her little brother’s dick, you pervert. The double standard was ridiculous. Trying to see her real little brother’s dick instead of just writing about it seemed way more unhinged, if you asked me. Plus, she’d already groped my body in secret.
Do you understand now, Kang Yunseo? You’re the far more depraved one. Even if a cop dragged her away yelling “This bitch!”, she wouldn’t have a single word to defend herself. It was that bad. Still, I didn’t have the courage to say it out loud.
“Come on, Yunseo. That’s not right. You’ve been writing so well until now. Why give up? Huh? If you don’t want to do it for me, at least do it for the readers. Once you decide to write something, that’s the attitude and courtesy an author should have.”
I quickly tried to soothe her. Besides, I even sponsored you. Was she really going to waste my money like that? I hadn’t sent her money with a 3.3% tax deduction just to have her quit halfway.
“……Then show me.”
“You’re still on about that?”
“If you don’t show me, I’m not writing either. Actually, I can’t write. Because I don’t know what it looks like.”
“Haa…… Fine. I’ll show you! Happy now?”
“Really?”
Why was she so excited? Was seeing her little brother’s dick really something to celebrate this much?
“But just for a second. Let me take a shower first. I’m worried it might smell like sweat.”
“……Do whatever.”
“Then wait a bit. I’ll be right back.”
Whew. I actually said I’d show her. I didn’t have this kind of hobby. I liked looking, but showing was a different story. I wasn’t some pervert.
Am I really going to bare my dick in front of my real sister? For real?
My mind was in chaos, but my body moved with surprising efficiency. I went into the bathroom, squeezed out a generous amount of body wash, and lathered my pubic hair thoroughly. I wanted it as clean as possible. Sparkling. Shiny.
What kind of cologne should I use? I also swapped out my precum-stained underwear for a fresh, nice pair. The expensive ones I’d bought for that body profile shoot were still in my room, packaging untouched. I tore it open in a hurry.
Hmm. They looked good on me.
What should I wear on top? Just my pajamas like this? A suit would be overkill. It’d look like I was trying too hard. Yeah. Keep it normal.
Knock knock.
“Uh, Yunseo. I’m ready.”
“……Come in.”
My heart was pounding harder than it had during my university interview. Harder than the first time I fired a gun in the military. Harder than presenting in front of hundreds of people.
When I stepped inside, Yunseo was sitting properly on the bed.
“Wait a second, Yunseo. There’s a condition first.”
“Condition? I already told you my place is off-limits, right?”
“Th-Then…… can you at least show me your chest?”
“What? My chest?”
“I mean…… it needs sexual stimulation to get hard.”
Half true, half false. This situation was so bizarre that I was already painfully turned on. Thankfully, I’d tucked it into my waistband earlier, so it wasn’t obvious.
“You need to see the finished product too, don’t you? Not just the normal state.”
“……To be precise, I want to see the whole process. From start to finish.”
“The whole process? You mean you want me to show you how it changes?”
“Yeah. In porn, they’re already hard when they show up. I don’t want that. I want to see exactly how it gets hard from the beginning.”
What am I, some kind of insect to observe? Like watching a caterpillar turn into a pupa and then into an adult that flies away—except it was my dick getting hard and growing.
“Then…… you’ll have to help me even more.”
“Can’t you just do it yourself? You’ve been getting it up just fine until now.”
“That was because there was enough stimulation. Like your ass rubbing against my dick, or your cleavage showing.”
“Seriously…… Even the story behind getting hard is ridiculous. The fact that it reacts to my body like that.”
“If it really won’t work, just think of it as paying a price. The price for seeing your little brother’s dick.”
“Haa…… Fine. Just looking, right?”
“Yeah. Uh, yeah.”
I almost bowed on the spot. Thank you. Three cheers.
“Idiot. Why are you so happy? I’m only letting you look. Anyway, wait a second.”
“Huh? Where are you going?”
“I’m going to wash up too. Showing it right away is…… embarrassing.”
“Why? It’s fine with me.”
“I think I smell a bit like sweat…… and I’m not wearing underwear either……”
“You’re taking it off anyway, so why do you need underwear? Don’t worry. The soft, sweet scent of your skin mixed with sweat is the perfect aphrodisiac. I could eat rice with that smell alone.”
“What a stupid…… explanation.”
“It’s kind of…… musky, I guess. Yeah. It’s the same smell that came from the panties you threw at me before. If you smelled it yourself, you’d understand right away.”
“Idiot. Shut up. Fine, I get it. I just have to show you, don’t I?”
Haa. This time it was Yunseo who let out a deep sigh.
“Take yours out first.”
“No way.”
“Stop bullshitting. Before I call the whole thing off.”
I shook my head furiously. My panties were about to rip from how hard I was. How could I?
“If you show me first, I’ll show you right after. Really. I swear on our parents.”
“You bastard. Why do you keep dragging Mom and Dad into this? We have the same parents.”
“Anyway. I swear to the heavens. I mean it.”
“Haa, fuck…… Haa. Making your own sister do something this embarrassing first. Some man you are.”
“You’re the older sister. You should set a good example.”
“Haa. Haa. Haa. Haa.”
Yunseo’s breathing grew rougher and rougher. Tears were even welling up in her eyes. Her hand slipped under her T-shirt. Then, slowly, bit by bit, she began to lift it.
