Event-1 (Branch Point 01)

The cafe was so empty that lazy afternoon it felt downright drowsy. A sharp yet sweet aroma wafted from the freshly roasted beans. That pungent coffee scent tickled my nose, somehow reminiscent of netorase itself.

Today's Da-bin kept glancing at her phone while working. As I passed by her side, I sneaked a peek at her screen. It showed a contact saved as "Junseo oppa." I couldn't read the messages, but... it gnawed at me.

I was the one who'd suggested netorase to Da-bin in the first place... Was I starting to suspect her now?

Today was the day we'd planned to invite Park Jun-seo for sex with Da-bin. She was probably just coordinating with that bastard. But my body reacted like an allergic fit, constantly on guard.

If only customers had flooded the place, time might've flown by... But today of all days, it was dead quiet. I killed time in the leisure, tormented by all sorts of delusions.

Evening rolled around. Park Jun-seo showed up at the house. We all drank together, building the mood. Then the main event began.

Da-bin... was letting Park Jun-seo suck on her breasts.

Slurp! Slurrrp! He devoured them with loud, obscene noises. Da-bin had already given him her right breast during their "date" last time. But witnessing that bastard actually sucking on my girlfriend's tits made my eyelids twitch and my fists clench.

Logically, I should be angrier about her allowing pussy access, but handing over her breasts—something she hadn't permitted right in front of me before—shook me even more.

Park Jun-seo, reading my turmoil like a book, teased her nipple with the tip of his tongue, zeroing in on her chest. His tongue writhed like some alien creature. Da-bin's pale pink nipples hardened in response to its movements.

The bastard obsessed over her breasts, as if their denial during the netorase massage and trip had left a grudge. Honestly, any guy would lose his mind over them. Peach-tinted nipples. Perfectly sized for play. If they'd been too big, they might've lost that fresh, pure allure unique to Da-bin. Her tits were optimized to drive men insane.

Slurrrp! Suck! Ngh! He lightly nipped her nipple. Da-bin couldn't hold back a moan from the intense stimulation focused on her chest.

"Ahh! Oppa..."

Her body trembled slightly under his caresses as she placed a hand on his head, stroking it gently. Giving up her breasts. Her pussy. I could endure that. But that gesture of hers tested my limits.

As if reading my mind, Da-bin glanced my way. Her face was the epitome of seduction, the kind that could devour any man. She wasn't the Da-bin I used to know. Overwhelmed by her aura, I could only stare, my cock rock-hard...

Park Jun-seo kept slurping away at her tits relentlessly. My emotions tangled into knots. But the thrill of taboo arousal made me itch to touch my dick.

I had to hold back this time. I didn't want to cum into the air again in front of that bastard. I barely suppressed the urge to stroke myself.

But... something about Park Jun-seo's actions felt contrived. Unnatural. He hadn't even touched her left breast. Her right was slathered in his saliva from all the licking and sucking—how could any guy ignore the other one?

Impossible. Especially with a woman like Da-bin. Had she told him not to touch her left breast? But her expression was too genuine for that. She stroked his head lovingly as ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠he fondled her chest.

Da-bin shot me another provocative look.

"Do-yoon oppa..."

"Uh... yeah?"

"You wanna do it?"

Her tone and expression teased me like a test. But I had no room to overthink—overpowered by her vibe, I just nodded.

"Yeah..."

Hearing my answer, Da-bin caught her breath for a moment. Then she turned to Park Jun-seo, who was still licking her nipple.

"Junseo oppa. Do-yoon oppa wants to... Can you let him go first?"

"Of course Do-yoon should go first. He's our Da-bin's boyfriend, after all."

Park Jun-seo said it with an innocent, matter-of-fact face. The casual tone and implication twisted the knife, but in this abnormal netorase setup, it only fueled my taboo thrill.

"Thanks, Junseo oppa."

He pulled away from Da-bin. She continued.

"Do-yoon oppa. Since you're my boyfriend, I'll let you go first."

I approached her like a man entranced. As I drew near, she reached into the bedside drawer.

"Wait, oppa."

"What's that, Da-bin?"

"I prepared a special event for you guys today..."

"An event?"

"Yeah! It's a special day today."

Da-bin called it a special day. But in my memory, today was nothing special. Not the day we started dating. Not when we moved in together. Not our engagement. Nothing.

!!!!

Anxiety crushed me. What "special day" was she planning to make this? With Park Jun-seo here, nothing good came to mind. The air felt oppressively heavy.

From the drawer, Da-bin pulled out... condoms.

"You know... oppa. Today is a safe day for me."

Those words made my heart pound wildly. Tension and excitement intertwined. Was she going to allow it...?

She licked her lips again.

"Since it's a special day... I'll let one of you cum inside. But you gotta pick the right condom, okay?"

What the hell was Da-bin thinking...? My mind reeled. But her brutal offer ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to let me cum inside already had my cock throbbing.

I picked one from the condoms she held out.

"You picked this one, oppa? No regrets?"

They looked identical on the outside. This was... pure luck.

I told her, "Yeah. This one."

"For real? Then I'll put it on for you special, oppa."

Something she'd never done before. She'd never fitted a condom on me herself. What had changed her like this...? Was it all because of me?

Da-bin slid the condom onto my cock. The slight brushes of her hand sent jolts through me, pre-cum already building. If I felt this good already, I'd cum too fast...

No control whatsoever. My only option: tease her to buy time.

With the condom on, Da-bin looked up at me. Her face flushed, eyes sultry. This new vibe from her stirred fresh urges in me.

A desire to pin her down and ravage her. Different from the pure lust her innocent side sparked—more primal. It awakened my raw male instincts, adrenaline surging from deep within.

I closed in on Da-bin. And took her left breast fully into my mouth.

Her soft flesh filled my mouth. Savoring her scent as I swallowed it, a thought resurfaced—from the regression into this loop. Something I'd wanted to ask her. I'd had chances before but forgotten.

But not the mood now. Next time.

I licked and savored her breast flesh. Meant to calm my raging cock through foreplay, but its softness only made me throb harder, urging ejaculation.

And... Park Jun-seo's piercing gaze burned. Dragging this out made me feel pathetic.

A battle between males... Shouldn't I rise to it?

Thinking of his stare ignited that deep adrenaline, pulsing through my veins. An indefinable aggression and competitive fire—not just dopamine.

Honestly... Dodging the main act ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠with foreplay wasn't my style. I'd always faced things head-on. Only my damn premature issue had robbed me of confidence in bed with Da-bin.

Right. Even if I came quick, I could prove myself with rounds.

I released her breast. Gripped her inner thighs with both hands, spreading them wide.

Her pussy, drenched in arousal. Was it from me...? Or had that bastard made her wet...?

The thought exploded something inside me. I pressed my glans against Da-bin's pussy.
