The Switch Flipped
“Ahhng… Ah…”
As my cock slowly began to push into my wife’s pussy, she shivered violently and started moaning. The sight made something snap inside me. I grabbed her hips and drove in with one brutal thrust.
“Ah… Ah… Oppa, it feels so good…”
Doggy style. It had always been my favorite position with her. The way her long, silky hair swayed and brushed across her back, the heavy bounce of her C-cup breasts, and that plump, juicy ass rippling every time I slammed against it—any man who saw Yu-jin from behind like this would lose his mind.
I gripped her slender waist like a handle and began pounding into her, driving my cock as deep as it would go. Claiming her from behind, I savored the way her tight walls squeezed my painfully hard shaft. The pleasure was sharper than usual, almost overwhelming.
Suddenly, the image of that man from the recycling area flashed through my mind—the young guy who had been staring at Yu-jin’s ass. The way he had devoured the sight of her narrow waist and round backside with his eyes… Now that same ass was jiggling obscenely under me, and the memory made my blood burn even hotter.
Slap!
“Ow… Oppa, why did you suddenly—?”
Without thinking, I had raised my hand and smacked her bouncing ass. Yu-jin’s pussy clenched hard around me in surprise.
“Sorry, did I scare you? It’s just… seeing your ass like this made me want to slap it.”
“No, I was just startled for a second…”
“You’re not upset, are you?”
“Not at all, Oppa… Actually, it turned me on a little.”
“Really? Then how about we try something new today?”
Her reaction was better than I expected. Gaining confidence, I started spanking her ass—never too hard—while I kept thrusting relentlessly.
“Ah… Hngh!”
Every time I drove into her, Yu-jin let out louder moans than usual. Each slap made her pussy squeeze me even tighter. Watching her, my mind began to wander somewhere darker.
In my fantasy, the young man who had been spying on her overpowered her by force and took her from behind. Yu-jin struggled, but she couldn’t escape his strength. Eventually she gave up. He groped her full breasts roughly, molesting her without mercy. She bit her lip to hold back her moans, but he wouldn’t allow it. He grabbed her face and forced his mouth onto hers. When she kept her lips tightly shut, refusing the kiss, he seemed to find her resistance adorable. His hands moved down to her plump ass, squeezing and kneading it like dough. Then he spat on his cock and pushed it between her cheeks.
Yu-jin finally surrendered. She stayed still, letting him use her, getting fucked from behind while she simply closed her eyes and endured it, praying for it to end quickly. All she could do was bite back her moans.
“Ugh… Already…”
The vivid fantasy pushed me over the edge. I sped up, thrusting harder, then buried myself as deep as possible and came inside her.
“……”
Yu-jin closed her eyes and stayed quiet as my cum flooded her.
“Oppa… you seemed like a different person today.”
“Did I?”
“You were a lot rougher than usual… It just wasn’t like you.”
“I guess I got extra excited because it’s been a while since we did it.”
I couldn’t possibly tell her the truth—that I had been imagining her being taken by force by a stranger. What the hell was wrong with me? Because of what happened today, it felt like some switch deep inside my brain had been flipped on.
After that, I had sex with Yu-jin several more times before falling asleep beside her, satisfied.
- Late Saturday morning
“Oppa, wake up already!”
I usually woke up before my wife, but after last night’s intense session, I had overslept for the first time in ages. Meanwhile, Yu-jin looked radiant, her skin glowing with vitality as she smiled brightly.
“Oppa, it’s Saturday. Want to go on a date outside for once?”
“Sure… It’s hard to find time on weekdays, and we’re always tired.”
I was still exhausted, but it had been far too long since we spent quality time together, just the two of us. I decided to go along with her mood.
“Have you thought about where to go?”
“Hmm… It’s been a while since we went downtown. Should we head there? We can grab dinner while we’re at it.”
“Let’s go downtown! There’s a new barbecue place that just opened. Everyone says it’s amazing.”
“Sounds good. Let’s get ready. I’ll just throw on a tracksuit. I’ll pull the car out first, so come down to the parking lot when you’re done.”
“Okay~ Oppa.”
I stepped out the front door and waited for the elevator. Just then, the door across the hall opened and a young man emerged carrying a trash bag.
“Hey there, Jihyeok. Taking out the trash?”
“…Hello, Uncle.”
The kid calling me “Uncle” was Kim Ji-hyeok, our neighbor. He had lived here before my wife and I moved in. He lived alone now. His mother had suffered from a long illness and passed away before he even finished elementary school. His father ran a small trading company that did well enough to support him without any issues. Once Ji-hyeok turned twenty and started university this year, his father apparently decided he no longer needed looking after and moved to Seoul alone to expand the business. That left Ji-hyeok living by himself in a 32-pyeong apartment.
An awkward silence stretched between us until, thankfully, the elevator arrived. We rode down together.
“Jihyeok, it’s the weekend. Aren’t you going out anywhere?”
“Ah… I prefer staying home alone. Where are you headed, Uncle?”
“I’m taking my wife downtown for a date. I hear there are lots of new places there these days.”
“Yes… I haven’t been that often, but since I go to university nearby, I’ve visited a few bars.”
“That’s right. You’re an adult now, so enjoy your college life while you can. Later on, you might want to have fun but won’t have the time.”
“Yes, Uncle.”
I sounded like an old man lecturing him. We parted ways on the first floor, and I headed to the parking lot, started the car, and waited for my wife.
About three minutes later, she came down.
“Sorry, Oppa. Did I take too long? Picking an outfit took longer than I thought.”
“…”
I was momentarily speechless when I saw what she was wearing. Yu-jin had on white skinny jeans and a navy short-sleeved knit top, with a mini crossbody bag slung over her shoulder. The outfit was casual but perfectly accented her figure.
She was tall for a woman—around five-foot-six—and had excellent proportions, so everything looked good on her. Even though she wasn’t working right now, no one would ever guess she was a married woman. She gave off an irresistibly attractive, youthful vibe.
I slowly drank in the sight of her. Starting from the bottom, her legs in those white skinny jeans were incredible. Her long legs, wide hips, and that plump, fleshy ass were all perfectly outlined by the tight fabric. It was unbearably sexy. From her thick thighs down to her slim ankles, her legs formed a perfect taper—like a work of art.
My gaze moved upward. The navy knit wasn’t too thick or too thin, and her C-cup breasts pushed out noticeably against it. The strap of her crossbody bag ran right between them, emphasizing her chest even more and giving her an almost lewd silhouette.
“You look really beautiful today, Yujin.”
“Hehe, it’s been a while since we went on a date, so I put in some extra effort.”
Even I couldn’t stop staring at her. I could only imagine how other people would react. Back when we were dating, whenever we went out, I always felt everyone’s eyes on her. Yu-jin herself seemed oddly oblivious to that kind of attention. At least, that was what I thought. I had no way of knowing what she was really feeling inside.
“Looking at you now, who would think you’re a married woman? They’d probably assume you’re a college student.”
“Oh stop it, Oppa. You’re exaggerating~”
Even as she said that, her face was lit up with a happy smile.
“Shall we get going?”
We got in the car, pulled out of the apartment parking lot, and headed downtown.
