Stepsis Satisfaction and the Great ED Revelation

After reconciling with my stepsister... I had always wanted our family to be happy. Sincerely. After Dad passed away, my stepmom had shouldered ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the family alone and taken care of me—she was someone truly worthy of respect. And Chae Na-hee, though a bit prickly, was my one and only precious little sister in the world.

But the shape of that happiness had just changed a bit.

In a world like this, there was no need to feel guilty about getting lewd with family. So was that why?

"Fuck my pussy harder."

The moment I heard those words from my stepsister, it felt like whatever thin thread was holding my sanity together snapped.

After that, it was pure beast mode.

I pounded her like a maniac, exchanging fluids like crazy. We siblings, who used to freak out if our bodies even brushed against each other, were now locking eyes and diving into sloppy, tongue-twisting kisses nonstop.

"Slurp, smack... ♡"

My stepsister feeding me her saliva. Feeling her scent fill my mouth made everything feel so surreal.

Who would've thought I'd end up doing this with her...

Like any siblings in Korea, we'd never shown affection—in fact, we'd cringe if our arms touched. But now we were doing way worse, and it only turned me on more. Her thick scent invading my mouth, I kept thrusting my hips.

"Hah, hah..."

I must've cum about two more times? She'd climaxed way more, but I hadn't kept count. One thing was for sure.

I couldn't stop...

Sex with my stepsister felt so good it made my brain tingle.

We went at it like animals until we finally peaked together, then collapsed on the bed, hugging as we passed out.

...Slept like a rock. Sweet, deep sleep after ages.

When I woke up shivering, the sun was already setting outside.

"Ah, what the..."

A glance over—Chae Na-hee had hogged the whole blanket. No wonder I was cold.

Checking the clock on the table, I realized it was almost dinnertime. I shook her awake.

"Hey, Chae Na-hee. Get up."

"Mmm... What time is it?"

"...7:30."

Almost three hours. Staring at her wriggling under the covers, I said,

"Go wash up first."

"No way. Wanna ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠sleep more..."

She mumbled sleepily, burrowing deeper, and I couldn't help nagging.

"Ah, get up already."

I yanked the blanket off without thinking.

Her naked body exposed. Seeing it snapped me back to reality.

Oh yeah... I fucked her.

Traces on her skin from where I'd sucked too hard in the heat of the moment. Lost in lust, I hadn't noticed, but now, seeing my marks on her pale skin after waking up, I felt like total trash.

Of course, that didn't last.

First times are the hardest—once you cross the line, guilt stops being a chain.

"Get up and wash."

Smack!

I slapped her ass. She glared at me.

"Ow, why'd you hit me?"

"'Cause you're not getting up."

Smack!

"Ah! Stop hitting me, you psycho!"

Her grumpy glare felt like the usual her. Kinda reassuring.

Once she shuffled to the bathroom, I threw on some clothes and stripped the bed. Couldn't sleep on those filthy sheets—planned to toss 'em in the washer. But carrying them out, I bumped into Stepmom in the living room.

"Oh, sweetie. Where you off to?"

"...Laundry."

My voice came out awkward. Normal chat with Mom? No biggie usually. But fresh off fucking my stepsister, holding sheets soaked in evidence? Felt like a death row inmate.

Trying to play it cool and slip by, she beamed and asked,

"Did you fuck Na-hee good?"

...Yeah, no escaping that.

"Heard you two going at it all the way out here."

"Ah, haha... Sorry."

"No, no. Seeing my kids make up properly makes me proud."

She grinned sweetly.

"How many creampies?"

"Dunno. Didn't count—three? No, four maybe?"

"Oh my!"

She looked impressed. My face heated up. But hers was ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠pure admiration.

"Hehe. My boy's got some stamina."

"...That much?"

"Duh. With all the ED guys these days—it's a social crisis. This? You're super healthy."

...Huh?

First I'd heard of that.

"Lots of guys with ED?"

"Yeah. New policies 'cause of low birth rates and ED. So seeing my son fuck his sister like that? Mom's thrilled."

Figured as much... I'd sensed it at the gym. Girls asking for my number just 'cause I got hard? Weird. Guess guys who can erect are rare.

Gotta look into this...

After dinner and a shower, back in my room, I searched on my phone.

Erectile dysfunction

"Hmm..."

Why hadn't I searched sooner? Internet's perfect for studying this twisted common sense.

An hour of news later, I got why the gym girls freaked over my boner.

"Real dudes who get hard are that rare?"

Erection rate under 10%. Guys who cum twice? Precious. Certify on Insta? Alpha Male treatment.

Even sex ed teaches girls how to make non-erect guys cum hands-free. Blew my mind.

Communities were the same.

Just from a quick browse. Tons of guys stressing over no erections.

Not all, sure. Some get hard fine, star in stamina ads or SNS fame. But they're top 0.1%—so-called Alpha Males.

"...What?"

Did I just level up in life?

Head was spinning.

"Mmm..."

Lounging, doomscrolling more, when—

Ding! KakaoTalk.

From my cafe boss, the manager.

"...Huh?"

Usually chill manager sounding urgent. I replied quick.

Shift cover. Coworker down with flu, needed a sub. No reason not to—free schedule, and she always treated me well. Payback time.

Grateful reply. But what followed? Not what I expected.

"What the hell kinda pic is this?"

Outta nowhere, a nude spread-eagle from the manager.

World's common sense got lewd, sure, but...

You're a married mom!

With a kid! This okay?!
