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

"Hehe♥ As expected, just using my hands isn't enough, is it?♥"

"Yes, Mother-in-law… Ugh…"

While I was driving, my mother-in-law reached over, took hold of my erection, and began stroking me. However, after experiencing far greater pleasures before, this level of stimulation felt insufficient.

'I wish she'd use her mouth… but that might make it hard to focus on the road.'

The thought of her servicing me with her mouth was tantalizing, but I hesitated to ask, fearing it might distract me too much.

As we stopped at another red light, my mother-in-law leaned closer to my lap.

"Since we're stopped, let me use my mouth♥ Haaah♥"

"Haa… Okay, Mother-in-law."

"Chomp♥ Woop♥ Chomp♥ Woop♥ Woop♥ Chuuuup♥"

Without missing a beat, she began sucking diligently, her mouth working with a rhythm that sent waves of pleasure through me. Unlike her hands, her mouth had a powerful suction that seemed to pull me in completely. The sight of her taking more than half of my length into her mouth only heightened my sense of dominance.

'I want to see her ass…'

Her upper body was pressed against my thigh, her ample breasts adding to the sensation, but my hands itched to explore further. I wanted to grab her perfectly shaped ass, which was just as enticing as her chest.

'Why am I hesitating? Isn't she my slave, after all?'

Yesterday, I had been unsure about training her, but now, there was no turning back. I had crossed every line imaginable, and hesitation wouldn't change anything.

Swoosh… Squeeze

"Huuup♥...Euuheeung♥ Oh, Master♥"

As I gripped her firm, peach-like ass, she let out a lewd moan, clearly pleased.

"Keep going."

"Yes♥ Woop♥ Chuuup♥ Woop♥ Chuuuup♥"

My hands were busy with her ass, my thighs enjoyed the soft pressure of her breasts, and my dick was lost in the warmth of her mouth. All of this was happening in the car, a scenario straight out of any man's wildest dreams. The satisfaction was overwhelming.

'It's ironic that the first person I'm doing this with isn't Yeonji but her mother… but it feels incredible.'

Press

"Huuuueeeup♥"

I pushed her head down, urging her to take me deeper, and she complied without resistance. A normal woman might have panicked, but my mother-in-law was no ordinary woman. She was my devoted sex slave, eager to please no matter the circumstances.

Swoosh

"♥"

I lifted her skirt, revealing her barely covered ass clad in a skimpy T-back. The sight and feel of her soft, bouncy flesh in my hands were intoxicating.

'Strangely, this is making me more focused.'

The intense, unambiguous pleasure seemed to sharpen my mind, allowing me to concentrate on driving while she serviced me. Sure, it was a violation of traffic laws, but as long as no one noticed, it was fine.

As we approached the department store, we stopped at another red light. I noticed a car in the next lane, its windows down. A man with a delinquent look and an average-looking woman were blasting music and laughing loudly.

Thump thump thump thump thump thump

"So, like, you know~"

"Yeah, hahahahahaha"

Their behavior was annoying, but I was in too good a mood to care—until the man glanced over and smirked mockingly. He wrapped his arm around his girlfriend, as if to flaunt his superiority.

'Oh, really?'

My car was far superior, but his smug expression suggested he thought he'd won simply because he had a woman by his side. It was irritating, especially since she wasn't particularly attractive.

"Mother-in-law?"

Noticing my reaction, she gestured toward the window controls.

"A-Are you serious?"

"Chwoooop♥"

Her answer came in the form of another deep suck, and with trembling hands, I lowered the passenger window.

"Heh… Just having a nice car doesn't mean… Huh?"

As the window rolled down, the man's smug expression froze. There, in plain view, was my mother-in-law, her ass exposed as she sucked me off, her breasts pressed against my thigh.

"Woop♥ Chuuup♥ Woop♥ Heup♥ Woop♥ Woop♥"

The man stared, dumbfounded, as his girlfriend tried to close their window, clearly embarrassed.

"Oppa… close the window."

But the man was too stunned to move, his gaze locked on my mother-in-law's mesmerizing figure.

"Chwoooooop♥"

"That's right, you're doing well, you bitch."

"Woop♥ Chuuup♥ Chomp♥"

She intensified her efforts, making sure they could hear every lewd sound, asserting her role as my devoted slave.

"Oppa, close the window!!"

"Uh, uh, o-okay."

Finally, he complied, and I closed my window as well.

"Hehehe♥ How was that, Master? With me, a woman like that is nothing, right?♥"

"Yes… Mother-in-law is far superior."

"Thank you♥"

Pleased with the compliment, she continued until we reached the department store. Even as we entered the underground parking lot, I hadn't finished.

"Phew♥… We can't go like this… I'll make you cum quickly♥ So please play with my ass while I do… Chwoooop♥"

"Hmm… Okay… Jeongyeon-ah… Ugh!"

This time, she went all out, her cheeks hollowing as she sucked with a fervor that left no doubt about her dedication.

"Kuh!! I'm gonna cum!!"

Brrrrt brrrrt brrrrt brrrrt

"Gulp♥ Gulp♥ Gulp♥ Gulp♥ Gulp♥"

She swallowed every drop, leaving nothing behind, and licked her lips with a lewd smile.

"Chwoooooop♥ Phew♥… Haa♥… Haa♥… I enjoyed that, lick♥"

After cleaning me up with a wet wipe, the thrilling drive came to an end.

....

'As expected, the attention is overwhelming…'

As we entered the department store, all eyes were on us—or rather, on my mother-in-law. Despite her face being covered with a hat, sunglasses, and a mask, her revealing outfit drew stares from everyone.

A woman with her level of sex appeal, dressed in a deeply revealing outfit, was impossible to ignore. Men couldn't help but look, and women shot envious glances her way.

"Hey, that guy looks like he's loaded."

"It's obvious he made her dress like that."

"Walking around with a woman like that… he must be a player."

'I'm not rich, I've only had one girlfriend, and she chose that outfit herself…'

I ignored the jealous stares and walked alongside her, pretending not to notice.

'It reminds me of going on dates with Yeonji…'

Though she never dressed as provocatively as her mother, Yeonji had also attracted attention thanks to her beauty and figure.

"Hehe♥ Everyone thinks I'm your lover or wife."

"Haha… Mother-in-law looks so young, after all."

No one would guess we were mother-in-law and son-in-law, given her youthful appearance.

"Since it's come to this, why don't we act like a real couple?"

"A couple?"

"Just for today's date."

She pressed her chest against me as she spoke, making it impossible to refuse.

'Well, I guess it's fine.'

"Yes, Mother-in-law."

"Hehehe♥ Then call me Jeongyeon and speak casually♥"

"Okay… I understand."

I felt like I'd been outmaneuvered, but the sensation of her chest against my arm was enough to keep me satisfied. And so, our not-quite-a-date began.
