Common Sense Altered: The Can Coffee's Reward

"Ayoung... what's going on?"

"Yes?"

I asked the question as she suddenly approached, but Lee Ayoung simply gave me a look that said I was asking something obvious. Without stopping, she walked right up to me... and dropped to her knees.

-Creak.

She spun my wheeled chair around so it faced her. I was frozen in shock, unable to move.

-Ziiip.

Still in that state, Ayoung reached out, pulled down my zipper, and even lowered my underwear. As my cock suddenly sprang free, a wave of embarrassment hit me and I started babbling nonsense.

"I... I might smell a bit since I sweated today..."

"Can't be helped. You gave me a can of coffee, so this much thanks is the least I can do. You know that too, right, Juwan?"

"Y-yeah... that's right."

Words I didn't even need to say slipped out on their own. I answered her so quickly because I was afraid she might change her mind. Kneeling there with her eyes fixed on my cock, she looked just as beautiful as always. Her glossy, neat short hair, the ear exposed on the left, the gently swaying earring, her clear eyes, and those lovely lips I knew so well.

Only then did I understand what "Common Sense Alteration" on the quest window truly meant. It literally meant rewriting ordinary common sense and changing it.

‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

I answered once more in a trembling voice.

"That's right... it's... common sense."

While I spoke, Ayoung brought her face closer to my cock and licked it with her tongue.

-Lick.

-Twitch.

"Hng!"

A sudden rush of pleasure made me flinch and moan. She looked up at me.

"Do you like it? My boyfriend always loved it when I did this before going down on him. You're the same, Juwan?"

I had never imagined Lee Ayoung could be this lewd. The realization left me inwardly shocked.

'Of course. If they're dating, they must have had sex and oral too.'

It felt like I was secretly watching the intimate side she only ever showed her boyfriend. My heart pounded like it might burst. Her usual calm, quiet greeting voice now sounded moist, as if whispering right into my ear.

While I was lost in her voice, Ayoung pressed her face fully against my cock and began sucking me in earnest.

"Slurp... chuup... tch..."

-Creak... creak... creak... creak...

As she moved her head back and forth, sucking my shaft, the chair started making its usual sound.

-Creak... creak... creak... creak...

Before long she buried her face completely between my legs and started working her tongue. Every time her soft, wet tongue brushed over my cock, my body twitched.

"Ahn!"

A strong jolt forced a moan out of me. Surrendering to the pleasure, I closed my eyes, then opened them again ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠and looked down at her head. I couldn't see her pure face, only the back of her hair. Her expression was hidden, but I could feel through my cock how focused she was on sucking me.

Without thinking, I reached out and started playing with her short hair. I'd always thought short hair suited her perfectly ever since I first saw her.

-Creak... creak... creak... creak...

While my fingers toyed with her hair, memories of her usual kind smile and greetings floated up. That innocent face, the short hair that matched it so well, her angelic smile, and her lovely voice.

-Creak... creak... creak... creak...

My fingers slid up through her hair until I was cupping her head. This was the same girl I'd always found too beautiful to even talk to. Strength gradually gathered in the hand resting on her head. I pushed down, forcing her head lower.

"Mmph! Mmm! Mmph!"

-Creak! Thud! Creak... creak...

Her body jerked slightly, but she didn't try to pull away. She only gripped my thighs tighter. The sensation of my cock pushing into her throat ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠shot through my entire body.

"Mmph! Mmm! Mmmph!"

-Creak... creak... creak... creak...

I could feel her tongue starting to move again. Every time I pressed down, she kept twitching while continuing to suck. Unable to hold back any longer, I came.

-Gush.

"Hah..."

Ayoung pulled her head back, breathing hard as if she'd been struggling for air. Tears welled in her eyes. Her usually refreshing smile was now flushed red, and my semen clung to her lips.

"Hah... hah..."

I sat back in the chair, panting, unable to move for a while. Intense pleasure still coursed through me. Then I realized Ayoung was staring straight at me. When I looked down, she spoke with her mouth full of white fluid, her words slightly muffled.

"Should I swallow?"

"...Yeah."

-Gulp.

I'd unconsciously used casual speech, but she didn't seem to notice. She swallowed the semen without any fuss, stood up, brushed the dust from her knees, and returned to her seat with traces still on her lips. Then she went right back to work as if nothing had happened.

Meanwhile, I sat there with my pants still open, breathing heavily. After a little time passed and I calmed down, I wiped myself with a tissue and zipped up.

Still flushed and panting in my chair, several new notification windows appeared before me.

'Huh?'

They showed the reward options for completing the quest. I didn't really understand what either of them meant at first. But as I stared, the words on the selection screen began to sparkle. Curious, I placed my hand over one of the glowing options, and a relatively simple explanation appeared.

'Not exactly the most helpful explanation.'

I tried the other two rewards as well.

'Hmm...'

Nothing really appealed to me. The descriptions weren't particularly helpful either. Besides, the only option I could actually afford was the Random Box, which cost just 1 CP.

-Beep.

-Thud.

Along with a simple notification sound, a plastic box just the right size to hold in one hand dropped onto my desk. Even now, it still didn't feel real. The quest window appearing, items suddenly materializing on my desk...

I glanced sideways. Ayoung was still working diligently beside me, a faint trace of semen on her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lips. I fixed my pants and turned back toward the computer. Everything had returned to an ordinary routine. What had just happened felt like a dream, yet the glistening semen on Ayoung's lips and the Random Box on my desk proved it wasn't.

After the reward selection faded like mist, another notification window remained in the corner of my vision.

[Time Remaining: 45 minutes 26 seconds]

[Time Remaining: 45 minutes 25 seconds]

[Time Remaining: 45 minutes 24 seconds]

'Huh?'

Energy surged back into my body, which had gone limp after climaxing. Come to think of it, the original quest window hadn't said anything about giving only one can of coffee. The timer simply kept counting down in silence. I reached into my pocket again to check my money.

'Damn it! No cash!'

I grabbed my card and decided to head to the 24-hour convenience store across from the student support center. I stood up.

-Rustle.

Hearing the sound and seeing my stiff expression, Ayoung spoke first.

"Is something wrong?"

"I really need the bathroom!"

I shot up from my seat. Ayoung seemed to be wrapping up her work. I rushed out of the student support center and ran like crazy.

"Huff... huff... huff..."

The convenience store was quite far, so I sprinted at full speed. My breath was ragged, yet I kept running with a flushed face, as if possessed. Soon the store came into view. The owner auntie stood behind the counter with a bored expression.

"Hello!"

"Oh my. What's the rush, student~"

"It's nothing!"

I gave a quick reply and hurried toward the refrigerated section with the canned coffee. There I spotted a six-pack on the bottom shelf and grabbed it immediately.

"I'll take this!"

"Studying hard, I see~"

"Thank you! Please hurry!"

After another half-hearted reply, I dashed back to the student support center with the six-pack in hand.

"Huff... huff... huff..."

My heart felt like it might explode, yet strangely I only felt winded, not truly exhausted. I opened the door, found my seat, and sat down. Six cans of coffee were now on my desk. Still panting, I pulled one out of the pack. My gaze, holding the can, turned toward Ayoung.
