The First Branch Point

I got caught by my live-in girlfriend while reading some doujinshi.

It might've been less embarrassing if it had been regular porn. Or maybe if it'd been a normal manga.

The doujinshi I was looking at was netorase. You know, the kind where a guy gets off on letting another man sleep with his woman.

The moment Da-bin walked in, my animal instincts kicked in, and I tried to close the window with the manga still open...

"Oppa! Freeze!"

Her high-pitched voice tickled my ears.

"..."

"Hands off the mouse!"

Da-bin's command left me no room to hit the close button. She froze me in place and marched right up to the monitor. Then she grabbed the mouse and started reading the doujinshi I'd been eyeing.

Da-bin's face grew stiffer by the second.

Click! Click!

It was like the agonizing wait while a teacher graded a test you'd bombed completely... My palms were slick with sweat.

"Oppa... So this is your thing?"

"N-no... I just stumbled on it by accident..."

Da-bin stared straight into my eyes. She was trying to look serious, but with those big, sparkling eyes of hers, she just came off as adorable. There was no helping it.

"For real?"

"Yeah! Totally! Who'd get off on pimping out their own girlfriend to other guys...?"

"Hmmm..."

Da-bin let out a suspicious huff, narrowing her eyes at me. I spotted a slight opening.

I had to exploit it. "Truth is, it's been a while since we last did it, so I was backed up..."

This much was true. Even though we lived together—my girlfriend and fiancée Da-bin—we hadn't had sex in over two weeks. And that was entirely my fault.

I struggled to get it up, and even when I managed, my premature ejaculation issues made it a ordeal. Plus, it wasn't exactly big...

Because of all that, I'd failed to satisfy Da-bin time and again, beating myself up inside. It had eroded my confidence to even bring up wanting sex first.

She probably had a rough idea of how I felt. She was sharp like that, even if she had her blind spots.

When ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠I spoke with such a defeated tone, sweet Da-bin softened a bit, pitying me as she patted my back.

"Oppa... If you wanted to, you could've just said so..."

"How about tonight then, Da-bin? Haha..."

To escape this mess, I flashed an awkward grin and propositioned her for sex.

She balled up her fist and slammed it into my chest with all her might.

Thwack!

"Ack!"

Who knew a girl's tiny fist could hurt this much...? Da-bin's punches always packed a disproportionate punch whenever I forgot about them.

"What the—trying to slink away like that?"

Guess I'd misread her. She wasn't about to let the netorase manga thing slide so easily.

But honestly, even that attitude was kinda cute. No matter how much it stung, she was still a girl—a cute, pretty one with an amazing figure to boot. Her punches were worth enduring for that brief pain.

The way she thrust her pale, delicate arm at me, fist clenched tight, was downright endearing. Like a kitten throwing tiny paws in a mock fight.

But given the gravity of the situation, this felt like a sincere punch... Still, to get out of this jam, glossing over it seemed like my only option.

"Forgive me, Da-bin—"

"Pervert oppa! I'm gonna shower! And don't think this is over—we're checking later!"

She called me a pervert but accepted my request for sex anyway. No matter how I looked at it, she had a heart of gold.

With her pretty face, bright personality, and kind soul, I ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠was one lucky guy to be dating her.

As Da-bin headed to the shower, I started erasing traces of the doujinshi ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠from my computer. I'd collected them meticulously, sorted by netorase themes. Downloading again would be easy enough, but it still felt like a waste.

The one I'd been reading starred a heroine named Miyu who did netorase for her boyfriend. What made it fun was how her feelings for the protagonist never wavered through it all. A straight-up NTR story would've wrecked me emotionally, but Miyu's unwavering devotion let me enjoy it with a thrilling arousal.

Truth be told, yeah, I had a netorase fetish. Plugging Da-bin into these doujinshi made for perfect fap material.

The urge had only grown stronger lately—I sometimes fantasized about actually trying it with her for real.

If... the opportunity ever came...

Could I really get Da-bin to do netorase...?

Click! Better safe than sorry—erase the evidence.

I trashed the Miyu doujinshi. Any cum I hadn't shot while reading it, I'd unload into Da-bin. That was my duty as her boyfriend and fiancé. But I worried if I'd even stay hard...

I headed back to the bedroom and lay on the bed. Stroking myself idly to prep an erection beforehand.

But it wasn't easy... I'd been rock-hard edging to the Miyu doujinshi moments ago, yet even with Da-bin—who turned heads anywhere—I couldn't get it up easily. Clearly, my issue was psychological.

Then... as I lay staring at the ceiling, something faint caught my eye in my vision.

This again...? I'd thought it was a hallucination from panicking when Da-bin caught me with the manga...

Now that I'd calmed down, the translucent message stood out even clearer.

Netorase Branch Point Created. No clue what it meant or why it appeared.

Was I losing my mind?

As I pondered gravely, more text wriggled into view, sharpening before my eyes.

The spot for regression points spun like a casino slot machine. The numbers slowed... randomly settling on 5.

If this message was real... did it mean I could spend those points to regress to this saved branch point...?

I had zero points now, so no way to test it. But if it worked... I'd probably proposition Da-bin for netorase with high odds.

If she refused or hated it, I could just regress to this exact moment.

If it was possible... I could make Da-bin do all those plays I'd only seen in doujinshi.

Da-bin, the most popular girl among guys in my university juniors... Sharing her with those guys...

Faces of my close college buddies popped into my head. The trio I still kept in touch with—my best friends.

Cheerful otaku Oh Han-gu. Cocky but deep down solid Choi Hyun-woo. Closest of all, the one I could confide everything in: Park Jun-seo.

If I gave those guys a shot at Da-bin, they'd worship me.

Well, except Jun-seo. With his killer looks, he had women lining up like trucks... Plus, he had a girlfriend now...

Still, Jun-seo was a guy too. He wouldn't say no to fucking Da-bin.

No matter how great he was, Da-bin looked way prettier than his girl in my eyes. Imagining even him with her...

My chest tightened with a mix of heaviness and rage, heart pounding. Blood surged through me.

And maybe because of that... my dick started hardening.

Anger? Arousal?

"Oppa?"

"Ah! All done showering, Da-bin?"

While I was lost in fantasy, Da-bin finished up and came out, towel-drying her hair. Her gaze shifted from my face to my crotch.

I was in loose sleep shorts. The thin fabric didn't hide my modest erection much.

"Oppa, are you... right now...?"

Her pupils dilated. She parted her lips, hesitating ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠to speak.

I could guess what she was thinking. She wanted to confirm if I was hard.

Given our history of erection fails during sex, it made sense. But even as her girlfriend, asking outright wasn't easy.

Time for some gentlemanly chivalry. "Yeah, Da-bin. Oppa doesn't feel tired tonight."

"R-really? My oppa's doing great...!"

Blushing, she cooed and praised me like a proud kid. Getting this hyped over a mere boner felt rewarding... but also humiliating.

But Da-bin, oppa doesn't have time for a shower. I couldn't hold back.

I pounced on her, unwashed and all.

"Kyaa! What, oppa?!"

I pinned her to the bed with my strength. Her shampoo scent filled my nose.

My frantic hands stripped off her shower robe. Those breasts—always stirring my lust. Not huge, but perfect handfuls. And flawlessly shaped.

I stuck out my tongue toward them.

Slurp! Smack!

"Ahh!"

Da-bin gasped raggedly, flustered by my beastly assault.

It wasn't just raging horniness driving me. I feared going soft during her shower.

But... in my haste, as I gripped my shaft to line up...

The fear came true.

My dick softened like a sea cucumber... I fumbled desperately, but once it flagged, revival was tough.

Da-bin caught my suspicious handiwork and opened her eyes.

"Oppa..."

"Da-bin..."

She hesitated, lips twitching.

"..."

"..."

"Would you like it if I slept with another guy?"

Her unexpected words hung in the air after a pause.

She'd probably sensed my netorase kink. Plenty of chances to snoop on my netorase-stuffed computer.

Today was just the official bust...

Her sudden question short-circuited my brain. But those words hit my nervous system like a bullseye.

"Would you like it if I slept with another guy?"

My frozen thoughts shattered as my dick surged back to life at her words.

Did she notice my heavy breathing...? Cautiously, she reached for my crotch, slender fingers probing my shaft.

"Haa—"

A mix of sigh and moan escaped her.

"Oppa... This netorase thing, right?"

Busted.

My heart sank.
