This Week's Common Sense Is Pretty Hot Too

I had to figure out the right answer.

But thinking that hard felt like more brainpower than I currently had on hand.

Right in front of me, Sohyun had pulled her blouse up and bared her breasts.

They were still covered by a black bra, but her chest was so full and heavy that even her pink areolas showed clearly around the cups.

What kind of jackpot is this?

Whatever it was, this week's altered common sense was another R-rated one.

Thank you, System!

It was definitely on my side. That much was clear.

But what was I supposed to do now?

Was just looking the whole point?

No way. She wouldn't have come over and sat right next to me if that was all.

Don't tell me I get to touch them?

Just imagining it made my heart feel like it was about to jump out of my mouth.

Our eyes met. She looked a little shy, a little nervous — an expression completely at odds with the way she'd just boldly flashed her chest.

It was way too cute. The way her eyes kept darting around was so adorable I thought I might lose my mind.

"……What are you doing?"

"Huh?"

"……."

Touching. It was definitely touching.

She'd just asked me what I was doing.

My hands itched. My palms felt like they were heating up.

Oh, man. I'm going to lose it.

There wasn't a single man on Earth who could keep his hands to himself with a pair of breasts like that staring him in the face.

I reached out on pure instinct. Our chairs were so close that my hand closed around Sohyun's breast as if it were the most natural thing in the world.

Soft—

Hup!

They were heavy. And insanely soft.

An overwhelming plushness spread across my entire palm, along with a springy bounce that was even better than I'd imagined.

This is Sohyun's chest……

My eyes felt like they were about to pop out of my skull.

I was only touching her over the bra, but the soft flesh spilling out over the cups squished and then bounced back under my fingers every time I squeezed and released.

Squish. Squish.

My hands didn't stop. Squeeze, release, squeeze, release.

Not enough. I want the bra off.

I checked Sohyun's face. She was looking anywhere but at me, clearly embarrassed, her lips pressed together as if she might be holding back a sound.

The clasp is…… in the front.

A front-hook bra. Could I take it off?

The fact that she still had it on made me wonder if the altered common sense stopped right here.

"……You can take it off."

"Huh? Really?"

"Yes. But…… not for long."

My fingers moved instantly. One little flick of the hook and the bra slipped free and dropped to the floor.

Bounce—

And then Sohyun's massive breasts swayed free, dancing into the open air.

"Wow…… They're beautiful."

"……."

"They're seriously so pretty, Sohyun."

I opened my palm and cupped the underside of one breast. The weight of it hit me all at once. Even the slightest lift sent a heavy ripple through it.

And then—

This is insane!

Right in the center of that full, heavy curve sat a small pink nipple. Tiny, tempting, and gorgeous. That cute little peak was already twitching.

There was no way I was just going to leave it alone.

I brushed my finger over it.

"Ahnn……."

At last, a moan slipped out of Sohyun.

"D-don't…… pinch ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠it."

"Ah, sorry."

So even the nipples were fair game.

Sohyun's eyes were darting all over the place. The fingers still gripping her blouse trembled with how hard she was holding on.

Screw it.

With a pair of breasts like this right in front of me, holding back was impossible.

From that moment on, my hands did whatever they wanted, kneading and groping Sohyun's chest without restraint.

"Haaahh……."

I pushed them together. I spread them apart. The way her soft flesh crushed under my knuckles and then sprang back was absolutely incredible.

"Whoa……."

I could feel her nipples stiffening against my palms.

Sohyun's getting turned on too.

Yeah. Anyone would, getting touched like this.

I swallowed dryly at the sight of those fully hardened tips, and before I knew it I was pinching one between my thumb and forefinger and twisting.

"Hnnngh! ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠O-Oppa……."

Even her moans were pretty!

Why did her voice sound so filthy when she cried out like that?!

Watching that proud, cool Sohyun melt into moans under my hands made my cock spring rock-hard on the spot.

"L-let go. It hurts."

Sohyun's head tipped back. Every ragged breath sent her huge breasts heaving and rolling inside my palms.

The pale line of her throat only pushed dirtier thoughts into my head.

That neck, those nipples…… licking's probably off-limits, right?

There was no way to know how far the line went. Getting greedy and making Sohyun hate me was something I had to avoid.

But sometimes you have to take the risk.

I cupped both breasts and brought my lips toward one of those stiff little peaks.

"Ah, you can't……."

Sohyun's hand pressed against my forehead and stopped me.

"Sorry……."

So licking was a no. There was probably some condition that only allowed touching.

It's fine.

These breasts alone were more than enough to make me happy. The way they yielded under my fingertips was pure bliss.

Ah!

A brilliant idea hit me. I stood up and moved around behind her.

"W-what are you doing?"

"I want to touch them from behind for a bit."

"J-just…… a little, okay?"

"Yeah. Thanks."

From behind, I filled both hands with Sohyun's breasts.

Whoa.

Front-on had been amazing, but groping them from behind was on a whole different level. I could feel the firmness hidden inside all that soft give.

Every greedy squeeze made Sohyun's shoulders jump.

Feels so good.

I wondered what she was thinking. Embarrassed? Flustered?

Or maybe it feels good for her too?

Wanting to hear that moan again, I pinched—

"Haangh!"

A jolt of pure pleasure shot straight up my spine. Feeling the heat of her breasts and the thudding of her heart under my hands was enough to drive me crazy.

"S-stop. Stop."

Sohyun pushed my hands away. I was reluctant, but I let go without a fight.

I…… with these hands……

I stared blankly down at my palms. Today, I had done something I would never, ever forget.

Sohyun quickly hooked her bra back on and pulled her blouse down. Once she had neatened her clothes, she moved back in front of me.

"……Give me a drink."

"……Yeah."

The atmosphere had turned awkward. But I liked it — I got to see a whole new side of Sohyun's face.

She couldn't meet my eyes, just kept drinking and snacking.

Now I have to figure out the answer.

Why had Sohyun let me touch her chest? I probably wouldn't get a straight answer, but I asked her anyway.

"Sohyun. About just now……"

"Don't ask me anything."

"……."

"Just drink. Both of us."

Was this the System's influence too?

"Is it because I paid?"

"……."

No answer. Same as before — whenever I got close to the truth, Sohyun went quiet.

Yeah. That has to be it.

I'd suddenly insisted on paying the bill. She'd scolded me for it, and then done… that.

So she treated the meal as a debt?

And let me touch her chest as a way of paying it back?

I'm not totally sure.

It was still fuzzy around the edges.

Should I just submit an answer?

I had one free answer attempt per day. Using it would tell me how close my guess was.

Too valuable to waste right now.

Midnight had already passed, so burning today's attempt would be a waste.

I need more confirmation first.

We drank a few more rounds before the night finally wound down.

"I'll clean up. You go on home."

"No. Let's clean up together."

Once everything was put away, I carefully held out two ten-thousand-won bills for the extra drinks we'd ordered.

"What's this?"

"For the extra drinks."

Smack—

Sohyun slapped me across the back.

"Ow!"

"Just go already."

"Just take it. That way I won't feel bad coming back next time."

"I want things to be a little more comfortable for me too, you know?"

"Please take it. Okay?"

"……Ugh, seriously."

I slapped the twenty thousand won down on the counter and bolted out the door.

"Bye! See you tomorrow!"

Then I ran straight home. With this, something should change when I showed up for work tomorrow.

Back home, I sat and thought it through carefully.

The snack food and the drinks. Roughly thirty thousand won, give or take. Considering how much alcohol we'd put away, she'd undercharged me.

"The bill itself was definitely right."

Then I remembered something else she'd said.

"That's right. She asked if I was going to save it up."

Which meant the money I spent could accumulate — and that later, I could cash it all in at once.

"What if…… the intensity goes up?"

Highly likely. That was probably why she'd asked about saving it.

"Don't tell me buying Sohyun food is what earns me the reward?"

I was losing my mind. Lightning struck right through my skull. This was by far the strongest possibility.

"Strictly speaking, I did buy her the food and drinks today."

I'd confirm it properly later.

"Eheheh."

Just looking at my palms made me smile. Today, these hands had freely groped Sohyun's breasts.

"That was a first, right?"

I was still so worked up that sleep wouldn't come easily. I finally managed to doze off and wake up the next morning.

I only had afternoon classes today, so I had some time. The second class ended, I bolted straight to the PC bang.

Sohyun was already there, and she greeted me with a smile.

"Welcome."

"Hey."

The PC bang was stocked with plenty of food.

"Sohyun. Did you eat dinner?"

"Not yet."

"I haven't either. Then let's each grab a burger."

"Huh?"

"I already paid."

"Ah, seriously…… Why are you like this?"

"Huh? Why?"

"It feels weird when you keep buying me stuff, Oppa."

"It's fine. You can freeload all you want."

I heated up a burger and handed it to her.

"A burger without cola is incomplete, right?"

Naturally, I paid for the cola too and passed it over.

"You left money yesterday too, and now……"

"Don't feel bad. It's fine. Totally fine."

"Just taking free food isn't my style."

"I really am fine with it."

Munch. Munch.

Even as she complained, she ate the burger with obvious enjoyment. And once we were done, the reaction I'd been waiting for finally came.

"……So what are you going ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to do now?"

Sohyun wouldn't meet my eyes. Embarrassed. Flustered.

I'm going to lose my mind. Seriously.

I wanted to touch ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠those breasts again so badly.

Hold it. I have to hold it.

I needed to raise the stakes. If the intensity scaled with the amount spent, then this was something I absolutely had to save for.

I might get her chest and her pussy all at once.

To lock it down for sure, though—

"Let me hit the bathroom first, then I'll tell you."

I sat down in a stall and spoke the answer out loud.

"This week's altered common sense is that Sohyun repays me when I buy her food. Oh — and it scales with the amount."

"Augh!"

Failed by a single percent. Still, I was basically there.

"So what did I get wrong?"

It's fine. It's fine.

Spending money on Sohyun earned me a reward — that much was confirmed.

"Time to start stacking it up."

If I did, something I'd only ever imagined might actually happen.
