The Last Day of the Pop-up

I pushed Mom back little by little, unbuttoning her shirt. As the buttons gave way, the T-shirt she’d been wearing underneath came into view. "This was a trap, wasn't it?"

"That’s… not it."

"The lingerie underneath was the real deal… that’s why you were so shy."

I took off her jacket and stripped the shirt off completely. Beneath the heart-patterned fabric, the shape of her breasts stood out, beautifully defined.

"No, don't… ah… we can't get caught…."

"Everyone’s asleep, it’s fine."

"Even so…!"

Mom’s backside pressed against the dining table where we all ate. I could hear the items on the table rattling from the movement.

"Are you really… going to do this…?"

"If we stop now after coming this far, you’ll just be more frustrated, Mom."

"That may be true, but…."

Just as people get angrier when something is snatched away, sexual desire only burns hotter when left unfulfilled. Having experienced it once already, there was no turning back now. Truth be told, I could have gone two or three rounds with Chaeyu, but I’d left the room, and I was quite pent up myself.

"Ugh…."

I covered Mom’s noisy mouth with my hand. My fingers slipped under her T-shirt, inching upward. Beneath the rolled-up fabric, her breasts were pressed into a pleasing shape.

'It’s the same as Chaeyu’s.'

The sheer lingerie Chaeyu had mentioned wearing. I’d already seen it all, but there was a certain thrill in ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠the partial concealment that suited the current atmosphere perfectly.

"Junsu…."

"Yes."

"You shouldn't… do this…."

"You say that, but your legs are wrapped around me, refusing to let me go…."

Though her words said no, Mom’s legs were locking me in place.

"Huu…."

Once again, a soft kiss. As a sultry moan reached my ears, Mom’s arms hooked around my neck.

"Ha, haa…."

"You secretly like being taken, don't you, Mom?"

"Shut… up…."

Mom lay back, and I pulled off her pants. As expected, she was wearing a matching set, and the inside of her panties was fully exposed.

"Move your hand."

"I’m embarrassed…."

"I’ve already seen everything there is to see, what is there to be embarrassed about…?"

"…Even so, embarrassment is embarrassment."

Shyly, she covered the most important spot with her hand while spreading her legs. I had no choice but to move her hand away by force.

"You’re already wet."

"Don't touch me…."

The fabric of her panties was soaked. A ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠little more friction and they would be ruined. Since Chaeyu had told me they were expensive, I just took them off entirely. Mom followed my lead obediently until they were gone.

"No… don't…."

"…!"

I pushed my cock in slowly, starting from the tip. Since she was already wet, there was no need for foreplay.

"H…!"

My cock sank in to the hilt, and I began to move slowly. Mom muffled her own mouth, trying her best to stifle her moans.

"Haa…."

Perhaps because of that, her pussy tightened around me, making my hips move faster on their own. I knew I had to restrain myself, to be patient, but my body wouldn't listen.

"Hng, ugh… ugh…!"

I gathered Mom’s legs—the same legs she was using to cover her mouth—and drove my hips into her. The creaking of the dining table and the clinking of the dishes on top grew louder.

Creeeeak—

The table let out a loud groan. I had no choice but to lift Mom up and move to the sofa.

"Ugh, haa…."

"How does it feel, doing this in the living room behind the family's back…?"

"Do you really have to ask that right now…?"

"Just kidding."

Mom sat on top of me, facing away. The line of her body, tapering down and then blooming into fullness at her hips, was a feast for my eyes.

"Hnnng…."

Mom began to move, rising and sitting in a slow, rhythmic motion. It was such a simple action, yet it felt incredibly good. The wet, squelching sounds only urged me toward my climax.

"Mom… wait a second…."

"Ugh…!"

I rose from my seat, grabbing Mom’s breasts as I thrust my hips. I wanted to move with everything I had, but the noise kept me in check. Even moving slowly, I couldn't stop the urge to finish.

"I’m coming…!"

"Ugh…!"

I thrust my hips, pressing against her as tightly as possible, before quickly pulling out. My semen spilled out, staining Mom’s buttocks as it trickled down.

"Haa… haa…."

As I wiped the semen away with a tissue, Mom took my cock into her mouth to clean it. She licked it meticulously, and a final drop of semen leaked from my urethra.

"……."

"Why, what’s wrong…?"

Mom puffed out her cheeks without a word. When she did that, she looked exactly like Chaeyu.

"Mom told you not to."

"I’m sorry…."

"What would you have done if we got caught!"

"……."

She seemed genuinely angry this time, so I couldn't joke around. Honestly, my brain just shuts off the moment I start thrusting. I really need to be careful from now on—

Creeeeak.

"Oh… what’s that? Mom, are you up? What were you doing?"

"Ugh?!"

The whispers in the living room were shattered by the sound of the door to Dad’s room opening. As soon as Mom heard it, she dashed into the bathroom.

"……Mom went into the bathroom."

"Oh… is that so? Tell her to let me know when she’s out. Dad needs to use the bathroom."

"Okay…."

My heart was pounding out of my chest. If we’d been even a second slower, we would have been caught.

"…Are you up?"

"Yeah, I’m up. Good work."

"U-uh… I’m going to wash up…."

"Yeah. Go change and get some sleep."

"Okay…."

"Hmm…? Did you spill water on the floor?"

"…I, I guess I did. I’ll wipe it up."

"Never mind. Just wipe it with your feet."

"……."

While Dad was in the bathroom, I quickly checked the area and wiped down the table and the floor. Mom glared at me the entire time I was cleaning.

"Mom."

"Oh. Are you up?"

"Yeah… I was heading to the bathroom."

On my way to the bathroom, I ran into Mom, who was putting on her shoes.

"Is today the last day?"

"Yes. I think I’ll be home a bit late, so keep an eye on the house. Make sure you eat well. Don't come by today!"

"Okay… …you’re wearing the scarf."

A bright, yellow-hued, flashy scarf was draped around Mom’s neck, displayed for all to see. It was worth buying it just to see her wear it.

"Of course. It’s a gift from my son, so naturally, I have to wear it."

"Do you like it?"

"Yes. It’s totally my style. How is it? Does it suit me?"

"Yes. It suits you perfectly."

"Alright, I’m off. See you this evening."

"Yeah—"

*Smooch.*

I saw Mom off to work, receiving a "have a good day" kiss from the morning. I went back inside, lay down, and closed my eyes.

"Hmm…?"

When I came to, I felt body heat beside me. Chaeyu was sleeping next to me, though I had no idea when she’d arrived.

'What time is it…?'

I checked the clock; it was 9:00 AM. Perhaps because of what happened late last night, my body felt incredibly heavy.

"Kuu…."

Chaeyu still seemed to be asleep, so I closed my eyes again. She should have been sleeping in her own room; when did she even get here?

"……."

A little more time passed. I forced my eyes half-open, and this time, she was facing me, sleeping. I thought she looked cute and closed my eyes again.

"Ugh…."

The sudden sensation on my lips made me snap my eyes open. But Chaeyu was still asleep, her lips merely brushing against mine—

"I know you’re pretending to sleep. Wake up."

"When did you find out?"

"…Just now."

It wasn't like we were drunk; who kisses someone in their sleep? Maybe if I were the one doing it, but not her.

"Can’t we just do it since we’re already here?"

"…I’m sleepy."

"What kind of excuse is that? It’s already 10 o'clock."

"Can’t I sleep a little more…? I’m exhausted from running around so much yesterday."

"Then I’ll do as I please."

"Fine…."

Just as I was about to surrender my mind to dreamland again, Chaeyu’s lips touched mine once more. I couldn't ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠wake up now, so I didn't react regardless of what she did. But Chaeyu took the initiative, sucking on my tongue and teasing me.

"Ugh… slurp…."

The strange sensation reaching my brain woke me up. We did this almost every day, so I should have been used to it, but it was beyond me why it felt so good every single time.

"Ugh…?!"

Chaeyu’s tongue slipped out, and something unfamiliar entered my mouth, stirring it around. It tasted slightly salty, so I assumed it was her finger.

"Oh, you’re up?"

"…I surrender."

To Chaeyu, who asked if I was up so nonchalantly, I finally raised the white flag. Chaeyu climbed on top of me and began to kiss me in earnest.

"Huuuuh…."

My cock was already throbbing, not having recovered from our session last night. But if I refused, she would definitely get sulky, so I had no choice but to accept it.

"Sluuurp… haa…."

"That woke me right up, thanks."

"Glad to hear it."

"Glad, my foot…."

After a deep, lingering kiss, Chaeyu pulled away and got out of bed.

"Come out quickly. I’m bored."

"Are we not doing more?"

"Dad’s here, remember?"

"…Right."

I felt unnecessarily embarrassed that I’d been doing such things while both of them were home. A pang of guilt toward Chaeyu washed over me.

"She said not to come today, for real."

"Is that so?"

"Why?"

"I don't know. She must be ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠busy since it’s the last day."

"Right. Don't go and get in Mom’s way for no reason."

Breakfast, eaten by everyone except Mom. Since Dad was off today, the house was bustling. As expected, we finished our meal with the side dishes Mom had prepared.

"Dad, you’ve never been there, have you?"

"Why would I go? I’d only be a nuisance."

"Aww. You can just buy some stuff and see Mom’s face."

"Wouldn't she be happy if you went, Dad?"

"Me? Nah. Forget it. She’d probably hate it."

"You never know."

Usually, there aren't many people who visit their wives at work like that. Besides, they weren't newlyweds; they were a long-term couple with a son in his mid-twenties.

"That’s true. You never know."

But that’s exactly why the surprise effect would be even greater. Doing something you don't usually do doubles the impact. It wasn't a bad thing, but a good one, so Mom would surely be happy.

"Then we should just go together."

"That’s right. Let’s take Dad’s car."

"But Dad’s tired…."

"Aww, don't be like that. Let’s go together."

"Alright. If Chaeyu says we should go, then we go."

"…What about me?"

Men really are helpless when it comes to their daughters. I finally understood why Dad was so well-informed about Chaeyu’s news.

"…Wait, aren't you supposed to be at work today?"

Suddenly, it hit me that Chaeyu had work today. This wasn't the time to be lounging around.

"……Right."

"I’ll drive you, Dad."

"Thanks, Dad…."

And just like that, a drive with just Dad and me, for the first time in a while, began.
