Episode 4

"Oppa~ Where are you? Is Mom upstairs?"

Thud, thud—

Kim Mi-in was climbing up to the small room on the second floor.

My hand still rested on my mother-in-law's chest as I lingered in the haze of sleep.

Tap, tap, tap—

"Mr. Youngjin! Wake up! Quick! Mi-in is coming up!"

My mother-in-law shook my shoulder urgently.

I jolted awake in surprise.

She hastily draped her slip over her shoulders.

Thud, thud, thud—

The sound of Mi-in climbing the stairs grew louder.

I snapped to full alertness and frantically searched for a place to hide.

Luckily, there was a tall wardrobe right beside us.

Creeeak—

I opened it, but it was packed full of blankets.

After pulling out about three layers, I quickly squeezed inside.

Swoosh—

Carefully closing the door, I curled up, holding my breath.

Moments later, Mi-in entered.

Click—

"Mom~ Are you up now? Still buried under the blankets? What's wrong? Sleeping in this late?"

"Ugh... Yeah. I must've been really tired. Are you feeling okay? You really should drink more moderately."

"Yeah. Hehe. I'm sober now. Guess I drank too fast yesterday. But, Mom, have you seen Oppa? His shoes are here, but I don't see him anywhere."

"Huh? Really? Youngjin— I mean, Mr. Park, where could he be?"

"That's weird... Oh, Mom! Why did you take out these blankets?"

"Huh? Blankets? Oh! These. They felt a little damp, so I took them out. Let's go hang them on the rooftop together, Mi-in."

"Right now? Ugh... Okay, Mom. Here, grab that side. Let's take them up."

Mi-in lifted one end of the folded blankets while my mother-in-law took the other.

Ahem, ahem!

She cleared her throat pointedly, signaling to me.

Holding the blankets between them, ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the mother and daughter headed up to the rooftop.

I immediately slipped out of the wardrobe.

Rushing downstairs, I searched for my clothes.

They were scattered near the sofa.

I gathered them hastily and locked myself in the bathroom.

Click—

Huff, huff...

Trying to calm my pounding heart, I turned on the hot water and stepped into the shower.

Ssshhh—

I washed my hair and scrubbed my body clean with body wash.

A short while later—

Knock, knock, knock—

"Oppa! Are you showering? That's weird... The bathroom was empty earlier."

"Huh? Can't hear you well! I'll be ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠out soon!"

I played dumb, though I heard her perfectly.

If I kept things vague, she'd let it go.

"Uhh... Okay, Oppa~"

Mi-in sounded suspicious but trailed off.

Click—

"Ahhh, that feels good!"

After finishing my shower, I dressed and stepped out, towel-drying my hair.

Mi-in was waiting with a bright smile, her earlier suspicion gone.

"Hehe. So I'll get to see you like this every day now? Even on weekends. Feels like you're really part of the family!"

"Uh... Yeah. Guess we're practically family now... Right, Mother-in-law?"

"That's right, Mr. Park. We're one family now. Let's all get along well. Hohoho."

Now wearing pajamas, my mother-in-law covered her mouth, giggling shyly.

And just like that, we became a family.

The times my mother-in-law and I got along only grew more frequent.

I quit my old job and switched to a related company.

It wasn't because of any trouble—just a better offer.

Though I was disappointed Mi-in and I wouldn't work together anymore, the lack of overlapping schedules turned out to be a blessing.

For example—

After our first time, right up until the wedding, I visited their house so often I nearly wore out the doorstep.

The reason was obvious.

That day, like many others, we had dinner together the night before.

I made sure Mi-in drank, and then...

We got busy.

Come morning, Mi-in and I got ready for work and left the house.

Of course, I only pretended to leave—I had already taken a half-day off.

Click—

When I opened the front door and stepped back inside, my mother-in-law greeted me with a coy smile.

Following our usual routine, I dropped my pants and underwear right there.

She knelt before me.

Slurp, suck, suck, suck—

Her butterfly lips pulled me in deep.

Her bangs swayed back and forth, and the scent of shampoo tickled my nose.

"Haah... Mother-in-law."

I stroked her hair with one hand while teasing her earlobe with the other, savoring the pleasure.

Gag, suck, suck, suck—

Her breathing grew ragged, clearly turned on.

By now, her pussy was surely soaked.

I gently cupped her cheeks and lifted her face, kissing her saliva-slick lips.

Slurp, smack, smack, smack—

Not exactly romantic, but the sweet taste lingered on my tongue.

One hand groped her chest, her stiff nipple rubbing against my palm through her T-shirt.

My face burned, blood rushing south.

I couldn't hold back anymore.

I yanked down her leggings.

Swoosh—

She was wearing the thong I'd bought her.

Her thighs glistened with slick arousal.

I spun her around, pressing her against the front door, then pulled her hips toward me.

Pushing aside the string of her panties, I thrust my cock straight into her wet hole.

Plop—

"Haahhhn!"

Thrust, pound, pound, pound—

A morning quickie right in the entryway.

For standing doggy to work, the height difference has to be just right.

If the man's too tall, he has to bend his knees awkwardly.

Same if the woman's taller.

The angle between her pussy and his cock matters too.

Only when the fit is perfect can you go hard and long without tiring.

Literally, the chemistry has to click.

And my mother-in-law and I?

We clicked perfectly.

Slap, slap, slap, slap—

"Haahhn! Mr. Youngjin! Harder! Fuck me harder!"

Her moans grew louder as she neared climax.

I matched her energy, ramping up the intensity.

Thud, thud, thud, thud—

A creamy mix of her juices and pre-cum dripped down.

"Haah, haah... Mother-in-law! You feel so good!"

"Aahhn! I love it too, Mr. Youngjin!"

Pound, pound, pound, pound—

We were racing toward the edge—

But then—

Ding-dong, ding-dong—

The doorbell rang.

We froze mid-thrust, bodies locked together. ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠

"Mr. Youngjin... Wait a sec," she whispered.

Pulling my cock out, she rushed to the intercom.

"Yeees? Who is it?"

Her voice was slightly higher, still buzzing with arousal.

[Mom, it's me. Can you grab the yellow document folder from the bedroom? I forgot it. Ugh! Late again...]

"Huh? Mi-in? Oh, the folder? Hold on."

She turned to me with a panicked look.

I snatched my pants off the floor and pulled them on.

She gestured for me to hide, so I grabbed my shoes and ducked into the living room.

Beep, click—

She unlocked the door.

Mi-in would be inside any second.

My heart pounded wildly.

Then, a brilliant idea struck.

Just as my mother-in-law returned with the yellow folder, nearing the door—

I stepped up behind her, yanked her leggings down, and plunged my cock back into her dripping pussy!

"Aahhn! Mr. Youngjin!"

Startled, she smacked my chest, but I didn't stop.

I kept pounding her from behind.

Slap, slap, slap, slap—

Even as she tried to push me away, I held her arms and kept thrusting.

"Mom~ Open up! Did you find it?"

"Uhh... Y-yeah. Here... Got it. Just a sec~"

My relentless fucking made her voice tremble.

Flustered, she cracked the door open, only peeking her head out.

Squelch, squelch, squelch—

I slowed my pace slightly but didn't stop.

"Mom, why's your voice shaking? Are you sick?"

"N-no... J-just a little c-cold."

"Oh. That's why you're barely opening the door. But the folder? I'm in a hurry, Mom."

"Uhhhn. H-here."

Still peeking out, she stretched her arm, handing Mi-in the folder.

"Okay, thanks, Mom~ But... You look pale. Seriously, don't catch a chill. Get some rest."

I sped up again.

Thrust, thrust, thrust, thrust—

"Uuuhhn! M-Mi-in~ You're gonna... be late!"

"Okay, Mom. Rest well~"

Mi-in hurried toward the door, looking genuinely concerned.

"Bye, Mom~"

Click—

The moment the door shut, I unleashed my pent-up lust.

Pound, pound, pound, pound—

Gripping her hips, I slammed into her with brutal force.

"Haah, haah... Mother-in-law. Want it harder?"

"Aahhn! Mr. Youngjin! Fuck me harder!"

"Haah, haah... Where? Where do you want it?"

"In my pussy! Mr. Youngjin!!!"

Slap, slap, slap, slap—

The door was still slightly ajar.

One of her ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠hands still clutched the doorknob.

Pound, pound, pound, pound—

"Aahhn! Mr. Youngjin!"

Her ass trembled against me, signaling her climax.

Squishhh—

Her pussy gushed, juices dripping down her thighs.

"Haah... Haah... Mother-in-law. I'm gonna fill you up!"

"Aahhn! Cum inside me, Mr. Youngjin!"

Splat, splat, splat—

"Haah! Hahh... Mother-in-law!"

Squelch—

I unleashed every last drop of my scorching load deep inside her.

"Aahhn, aahhn, aahhn..."

I hugged her trembling body from behind, groping her peach-like breasts.

"Haah... Mother-in-law. That was amazing, right?"

She turned and lightly smacked my shoulder.

"Sigh... You're such a devil, Mr. Youngjin. But... I've never felt this kind of thrill before. Hohoho."

Still buried inside her, I turned her face to mine and kissed her deeply.

As she faced me, adjusting her stance, my cock slipped out—

Drip, drip—

Thick ropes of cum spilled onto the floor.

Smooch, smooch—

Still kissing her, I spanked and kneaded her ass.

"Wanna try something even more thrilling?"

"Huh? There's more? Like what? Hohoho."

"Hahaha. Our wedding's coming up soon, right?"

I whispered into her ear.

"Eeeh? Really? You're unbelievable, Mr. Youngjin. How do you come up with such naughty ideas?"

"What's wrong? Don't like it? Hahaha."

"Nooo! I love it! Hohoho."

Scooping her up, I carried her to the bed.

And we got busy all over again.

Time flew by.

A month later, Mi-in and I held our wedding.
