I Fucked My Mother-in-Law to Marry My Girlfriend

Squeak, squeak, squeak, squeak, squeak, squeak.

"Ooooh♥ Ooooh-heeheehee♥ Hiiiing♥ Master's cock is amazing♥"

My mother-in-law lay face down on the floor, her hips shaking rhythmically as I pounded into her.

"Who told you to grip me so tight!"

Slap!

"Buh-heeheeheehee♥ I'm sorry♥ My pussy just loves Master's cock so much, I couldn't help it♥"

Squeak, squeak, squeak, squeak.

Even as I slapped her ass, her hips didn't stop moving. Lying flat on the floor, she submitted completely, her vulgar movements only heightening my sense of dominance.

'My mother-in-law's pussy is so tight—it's hard to believe she's given birth before!!'

Of course, she's the first woman I've ever been with, but there's no denying how incredibly tight she is. Her late husband had a small cock, and she'd only ever used a regular-sized dildo, which kept her pussy as tight as a young woman's. On top of that, she takes great care of her body, exercising daily, so physically, she could easily pass for someone in her twenties.

Naturally, her pussy gripped my above-average cock with an intensity that left me mindless with pleasure.

"Slap my ass more, please♥ Mark me with your handprints, Master♥"

Her masochistic words only fueled my dominance, drawing out the sadistic side of me and pulling me deeper into the pleasure.

"You vulgar pig!"

Slap!! Slap!! Slap!! Slap!!

"Ooooh♥ That's it♥ I'm getting my pussy ravaged while my ass gets slapped♥"

It's hard to call it ravaging when she's clearly enjoying it so much, but as a submissive woman, she was dripping wet from the sheer pleasure of being used by a dominant man.

"Haa…haa…..haa…"

"Heeheehee♥ M-my ass feels so… haa♥"

Squeak, squeak, squeak, squeak.

Her ass was bright red from the slaps, but her hips kept moving, never stopping her service.

'I can't hold back anymore!'

Clench.

Brrrrt, brrrrt, brrrrt, brrrrt.

"Oooooooooh♥"

Pshooooooooot.

We climaxed together, her pussy squeezing tightly as I filled her with my release. She shuddered, her pussy squirting intermittently as if she were having multiple orgasms.

"Heehee♥….Haa♥….My pussy has been completely defeated by Master's cock♥"

Tzzzz.

"Haa♥ What a waste♥"

When I pulled out, my semen spilled onto the floor, and she immediately turned to clean me up.

"Let me thank Master's cock….Mmmph♥ Chooop♥ Heup♥"

"Good…..you're doing well."

Swish, swish, swish.

"♥"

She carefully licked my cock clean, her expression so adorable that I couldn't help but stroke her head. She smiled happily, clearly enjoying herself.

"And…..lick♥"

'Th-that too….'

Once she finished cleaning me, she started licking up the semen that had spilled onto the floor.

"Thank you for the meal, Master♥"

She licked it all up, then opened her mouth wide to show me she'd swallowed every drop.

"Good job, Jungyeon."

"Yes, Master♥"

I praised her, calling her by her name, and she kissed the tip of my cock, delighted.

"Hehe♥…..You've become even more like a Master in just one day♥"

"R-really….hahaha."

It was a strange compliment, but since we were both satisfied, I just laughed it off.

"I'd love to shower together, but…..it'll be difficult with so many servants around."

We were both sweaty and covered in fluids—me in saliva and her in pussy juice and semen. A shower was necessary, but with the staff around, it wasn't feasible.

'If they weren't here, would you have wanted to shower together?…..'

Given how many boundaries we'd already crossed, showering together might have felt almost normal.

'Well, we did shower together yesterday, so does it even matter?'

I was starting to notice how my mindset was shifting because of her, though I wasn't fully aware of it yet.

"Let's head to the department store after we shower….I'll have the car waiting at the entrance, so please go wait there first."

"Ah, yes, I understand, Mother-in-law."

Since it would take her longer to get ready, I decided to wait in the car. We each went to our rooms to clean up.

By the way, I told the servants that the mess on the floor was just water. I felt a little guilty making them clean it up.

...

After showering and changing, I stepped outside to find a car waiting for us.

"This has to be worth at least a hundred million won..."

I'm not much of a car enthusiast, but even I could tell this was a luxury vehicle, the kind only the wealthy drive.

'Well, for my mother-in-law, this is probably just normal….'

For someone of her status, a car like this was nothing out of the ordinary.

I got into the driver's seat, marveling at the interior, when my mother-in-law appeared and opened the car door.

"M-Mother-in-law?!"

"Oh my, what's wrong, my dear son-in-law♥"

She smiled playfully, and my eyes widened in shock.

"Your outfit is… quite daring."

"Oh my, is it?♥"

She struck a pose, emphasizing her voluptuous figure. Her outfit looked like something you'd wear to a club—a black off-the-shoulder dress with a deep neckline and a skirt so short it barely covered her thighs. On anyone else, it might have looked tacky, but on her, it was undeniably sexy.

"Gulp…"

"Hehehe♥ Judging by your reaction, I think I chose the right outfit♥"

She seemed pleased with herself.

"W-well, even so, wearing something like that to a crowded place like a department store is a bit…"

"Oh my? What's wrong with my outfit?♥"

She deliberately cupped her breasts as she spoke, and I couldn't look away.

"I guess this kind of outfit doesn't suit someone my age, right?"

"N-no! It suits you very well!"

If anything, ten out of ten people would agree it suited her perfectly.

"Then there's no problem, right?"

"Yes…..yes?"

"Hehehe♥ If my dear son-in-law likes it, then that's all that matters♥"

Before I knew it, I'd agreed, and she got into the car without changing.

"Okay, let's head to 00 Department Store."

"Yes…I understand, Mother-in-law..."

I knew other men would be staring at her, and while it made me uncomfortable, it also gave me a sense of pride that she was mine.

"I thought a flashy car might make you uncomfortable, so I chose something more moderate. Is it okay?"

"Ah, yes, it's fine..."

'So this is what you consider moderate…'

Driving a car worth hundreds of millions of won made me uneasy, but I could tell she'd put thought into choosing it.

And so, we set off for the department store.

It was a weekday afternoon, so traffic wasn't too bad, but we kept hitting red lights.

Glance.

Despite my efforts not to look, my eyes kept drifting to her outfit. Every time we stopped, I'd sneak a peek at her. Her short skirt had ridden up, revealing her panties, and even though I'd seen her naked, the sight of her in such a revealing outfit was thrilling.

"Hehehe♥…..Master isn't concentrating on driving."

"Ah…th-that's…"

She caught me looking and smiled seductively.

"Where were you looking? My breasts? Or my ass? Or…my panties?♥"

She knew exactly where my eyes had been. She didn't adjust her clothes, instead enjoying the attention.

Thump, thump, thump.

"To think you just came inside me, and you're already hard again….you're really something else♥"

Her outfit and behavior had me fully erect, my cock straining against my pants.

She licked her lips and slowly reached for me.

Swish…..swish.

"M-Mother-in-law?!"

She unzipped my pants and pulled out my cock, which was already leaking precum.

"It must be hard to drive like this….I'll help you♥"

Tap, tap, tap, tap, tap, tap, tap.

"Ugh! M-Mother-in-law!"

The sensation of her hand on me while I was driving was overwhelming. Thankfully, my years as a delivery driver kept me focused, but the thrill of doing this in public was undeniable.
