Selected as the Golden Penis

“What the fuck.”

I swiped at the status-window-looking thing floating in front of my face. Swish—swish—

My fingertips just passed straight through it. It refused to vanish from my sight.

“What the hell is this.”

Fuck, what is going on. Did I drink way too much last night?

“Ugh… I’ll just sleep more and deal with it later…”

I closed my eyes again.

“Hey, what about Seongmin?”

“Him? Probably still asleep.”

“Yeah?”

“Ugh…”

Voices from outside the room pulled my eyes open.

What time is it?

“What? Not that long… but why’s it so dark outside?”

I rubbed my eyes and checked the time again.

“Holy shit, I slept like a rock.”

It was Friday, so I’d gone out drinking with friends for the first time in a while. Never thought I’d open my eyes again at half past eleven the next night.

Maybe from sleeping so long, my throat felt like it was cracking open with thirst.

“Fuck, I’m parched.”

I opened the door and stepped out for water.

“Kyaa!”

“...?”

In the living room were my sister and her friend Gayeong. Gayeong’s most striking feature was a pair of breasts so huge you couldn’t even guess how many cup sizes they were.

“Oh, hey Gayeong-noona.”

“Uh! Uh…”

Gayeong’s face turned bright red. What’s with her today?

“Hey, you crazy bastard!”

My sister smacked me hard across the back.

“Ah, what now!”

“What kind of guy walks out in just his underwear!”

“So what!”

“Has this kid lost his mind? Get some damn clothes on and come out!”

She shoved me back into my room. But I’m thirsty as fuck.

Only then did the status window floating in front of me catch my eye.

“Whoa… am I actually losing my mind?”

I scratched my head, rubbed my eyes, slapped my cheeks, waved my hands through the air…

It wouldn’t disappear. Not even a little.

“Is this… real?”

Gayeong had been several times more embarrassed than usual. I’d known her for years through my sister, and it wasn’t the first time she’d seen me walking around the house in just my underwear. Sure, she always deliberately avoided looking at me in that state, but still.

“Fine, let’s say that checks out. Then what the hell is this?”

The status window floating right at the top.

I couldn’t even begin to process it. Could the words “golden” and “penis” even go together like that?

I tapped the status window, and another one popped right out.

“Oh… so that’s what this means.”

Roughly translating, anyone I had sex with would feel twice as much pleasure.

“Then what’s with the ??? down there…”

No separate explanation, but it looked like I was going to have to put this Golden Penis to use.

No way my dick actually turned gold… right? Nah, no way…

I tugged my underwear down a little and checked.

Thankfully it wasn’t gold-colored, but…

Was my dick always this big?

A size that was hard to believe belonged to a Korean guy. Even grabbing it with both hands, I’d still need another one to ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠cover the rest.

Somehow this thing was actually fitting inside my underwear…

Alright, so what now?

A gender-reversed world plus a Golden Penis… isn’t this ridiculously convenient?

Thinking about the old world’s gender dynamics made it simple. An average-looking woman propositioning a guy for sex? As long as she didn’t have an STD, nine times out of ten he’d go for it.

And I’ve got the Golden Penis on top of that.

This was the moment I became ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the sex master of the new world.

So who should I try this Golden Penis out on first…

I didn’t even need to think hard. Gayeong-noona, who’d come over to sleep at our place. I’d wanted to fuck her senseless for ages.

Time to fuck Gayeong-noona.

I threw on a random T-shirt and some shorts and headed out to the living room.

“Better?”

“...”

“What now.”

“...Look at yourself.”

My sister dragged me back into the room, leaving a tomato-red Gayeong behind.

“Ah, what is it this time for real.”

“Are you doing this on purpose?”

“Doing what?”

“Haa… a guy needs to know how to be careful…”

She pointed at my chest.

“What, I’m wearing a shirt.”

“Not that. You’re not wearing a nipple patch?”

“...What kind of bullshit is that.”

“Hey! What do you think Gayeong’s gonna think seeing you showing through like that! Especially when she’s a virgin who’s weak to stimulation!”

Wait, Gayeong-noona’s a virgin?

With that face and that body, she’d somehow managed to hold out all this time.

“It’s barely even showing.”

“Hey! Then at least change into a black shirt. Haa… seriously, what’s with you. Normally when Gayeong comes over you don’t even talk to her.”

“...I don’t?”

What, did the world changing rewrite all my past behavior too?

Whatever, doesn’t matter.

I pulled a black T-shirt from the closet. Then I immediately yanked the one I was wearing up and off.

“Hey, hey!!”

“What.”

“Why the hell are you stripping right in front of me!”

“What’s the big deal.”

What, sis. Are you looking at me as a man now?

“Haa… I’ll wait outside, so change and come out.”

She left. I switched into the black shirt and stepped out of the room.

“Gayeong-noona.”

“Euh, y-yeah?!”

“Staying over tonight?”

“Huh? Uh… th-that… ah, nothing’s decided yet… Ah! No! I-if it bothers you I’ll just grab a taxi later…”

What’s with this noona. She used to sleep over just fine before.

Is this the gender reversal?

“Oh…”

I glanced at my sister.

“...What.”

“I’m fine with it.”

“Since when are you like this?”

“Like what?”

“You used to throw a whole fit about how girls weren’t allowed to sleep over at the house…”

“I did?”

Past me of this world… what kind of life were you even living.

“Gayeong-noona’s fine.”

“Yeah? Gayeong, he says you’re fine.”

“Euh, y-yeah?! Uh… uh! Thanks!”

Gayeong was fidgeting like a pure virgin guy who’d never even talked to a girl. Of course, looking at her face and those breasts, it just came off as cute.

“So, what were you two up to before coming here?”

“Just drinking. Gayeong missed the last bus so I brought her over.”

“Ah, that so?”

Now that I looked, both of them smelled faintly of alcohol. There were even empty beer cans on the table, whether they’d bought them or not.

The three of us chatted about this and that for a while, until my sister stood up.

“Alright, I’m gonna go wash up.”

“Uh, uh?”

“Talk with Seongmin for a bit.”

She went into the bathroom, leaving just me and Gayeong-noona.

“...”

“Noona, were you always this quiet?”

“Euh, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠y-yeah? Ha, haha… i-is that so?”

Fuck, her being embarrassed is so damn hot.

I shifted over to sit right next to her.

“S-Seongmin?!”

“What?”

“Huh? Ah, n-nothing… j-just… having a guy like you get this close makes me a little…”

Ah, she’s so fucking cute.

Should I tease her more?

“A little what?”

“Huh? Ah, uh… a little… n-nervous? I guess?”

“Oh…”

Fuck, I want to just take her right now.

But that might make me look too easy. Not that I particularly cared, but I wanted to mess with embarrassed Gayeong-noona a bit more first.

Then my eyes drifted to her chest.

“Noona, you work out your chest?”

“Huh? Ah, these…”

Gayeong’s face flushed an intense red.

“S-sorry… they look so bad, right…”

“What does?”

“They’re just so big… ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I even tried losing weight to make them smaller but the breast fat stayed the same… s-sorry… I’ll put on a cardigan.”

What? Why would you cover up something that good.

I caught her hand before she could move.

“S-Seongmin?!”

“Why cover them. They look good.”

“Euh, y-yeah?! My breasts…?!”

“Noona’s breasts are pretty.”

She’s not even getting mad when I’m staring straight at them like this.

Gender-reversed world, hallelujah.

“Really…?”

“Can I touch them?”

“Euh, y-yeah… if you’re okay with it…”

I poked one of Gayeong-noona’s tits with my finger.

“Euhht…!”

“Whoa, the bounce on these is insane.”

The moment I pressed in, the springiness lightly pushed my finger back out.

“This size and this elasticity…?”

“S-sorry… my breasts are ugly…”

While poking them I noticed something odd.

“Noona, you’re not wearing a bra?”

“Underwear? I am wearing it though?”

“Not panties.”

“...?”

What. In this world women don’t wear bras?

Fucking thank you.

I poked the nipple faintly poking through her tank top.

“Heuht…!”

“Must be because they’re so big.”

“Th-there…!”

Gayeong reacted with extreme sensitivity. Fuck, this is so hot.

I gently teased her nipple with my fingertip.

“How is it, feel good?”

“Euh, y-yeah…”

“Raise your arms up.”

“Huh? Like this…?”

She lifted her arms. Through the single layer of tank top, her braless nipples stood stiff and fully visible. Even her slightly flushed underarms looked good.

“Try not to make any noise so my sister doesn’t hear.”

“Huh? Heuhk…!”

I tormented both nipples at once with both hands.

“S-Seongmin…! Th-this…! Euhheup…! Heut…!”

Gayeong couldn’t keep her body still under the stimulation.

“Oh, noona’s nipples are getting bigger.”

“Th-that’s…! B-because you’re touching them, Seongmin… heuk…!”

“Feel good? Does it feel good when I do this?”

I gave the tips of her nipples a light pinch.

“Eukgeugeuk…!!”

Gayeong’s back arched like a bow and her body bounced lightly a couple more times.

“Haha, what the hell, noona. Why’s your waist moving when I’m just touching your nipples.”

“Th-that’s…”

I rested my hand between her legs. Through the thin shorts I could feel the dampness.

“You’re wet?”

“...!!”
