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

"Uwoob♥ Chuub♥ Haaeb♥ Uwoob♥"

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

I had come here to greet my mother-in-law and formally ask for her blessing to marry Yeonji. But now, here I was, having my dick sucked by her.

'What kind of technique is this?!'

Not only was she taking my thick length into her wide-open mouth, but she was also using her throat to swallow more than half of it. Her tongue danced skillfully, stimulating every inch of my shaft and the head of my cock.

'Is she really someone who hasn't done this in 20 years?!'

"Haaeb♥ Hehehe♥ It seems my new master is enjoying my fellatio♥"

My mother-in-law looked up at me with a lewd smile, clearly pleased by my reaction—and my dick's.

'That expression… it's so much like Yeonji's…'

To be precise, it was the same look Yeonji had when she was aroused—flushed cheeks, a gaze filled with desire, like a female in heat. The resemblance between mother and daughter was uncanny.

"I'm just giving you a light greeting for now… but am I making you feel better than Yeonji?"

"W-Well, that's…"

"Slurp♥"

"Ugh!"

Honestly, it felt incomparably better than anything I'd experienced with Yeonji. Until now, Yeonji and I had only been with each other. We were each other's firsts, and our inexperience showed.

"Yeonji is practically a novice in this area. She'd probably struggle just holding a dick in her mouth♥… Like this♥"

"S-So deep… Ugh!!"

This time, she took me deep into her mouth, swallowing almost all of me, her throat tightening around my shaft.

"Phew♥… It's my first time with a dick this long and thick, so it's a bit hard to take it all♥"

Her techniques were on another level compared to Yeonji's. The elegant, aristocratic woman I'd met earlier was gone, replaced by a seductive temptress.

"How is it?… Please, be honest with me♥ Haaeb♥ Chuub♥"

"M-Mother-in-law, it feels better with you!"

"Hehe♥ Thank you, Master♥"

"Heeuk!?"

The way she called me "Master" with that lewd smile sent shivers down my spine. My male instincts, long suppressed, were beginning to awaken.

'N-No!! I can't do this with my mother-in-law!!'

Even as my dick was being pleasured, my rational mind hadn't completely collapsed. I had to find a way to turn things back to normal.

'I've vowed to love only Yeonji for the rest of my life. To be with another woman—especially her mother—and become her master? This is a betrayal to Yeonji.'

"M-Mother-in-law, stop!"

"Hooey♥… Is something wrong?"

"Y-You shouldn't be doing this! Let's pretend I didn't hear anything about becoming your master. Let's forget this ever happened and just talk about…"

"Hoo…"

She wiped her mouth, her expression tinged with disappointment at my resistance.

"It seems Joohyun hasn't fully understood yet…"

"Huh?"

"If you asked Yeonji to choose between you and me… who do you think she'd pick?"

"That would be… you, Mother-in-law…"

Yeonji loved me, but I knew her well enough to know she'd never abandon her mother—even if it meant giving up on me.

"Exactly… And if I wanted to, I could keep you and Yeonji apart forever, ensuring you never see each other again."

"No, it wouldn't come to that…"

"You might think it's extreme… but I've run out of patience."

She placed a hand on her chest, her gaze piercing.

"Ever since I learned you and Yeonji were dating a year ago, I've been dreaming of my new master, waiting patiently."

Her sincerity was undeniable, but that only made things more complicated.

"My body craves a master—to obey, to submit, to be dominated, to be trained, to be reduced to nothing."

Her voice was low, almost a whisper, filled with desperation.

"For over 20 years, I've endured, trapped by my husband's orders, unable to satisfy my desires."

She moved closer to me.

"You are my only savior now… If you refuse me… I'll marry Yeonji off to another man—someone who will accept my offer."

"No way!! Yeonji with another man… Ugh!!"

The mere thought of it made my blood boil. I jumped to my feet, glaring down at her.

"That's the look… You had the same expression when you first saw me—like you wanted to claim the woman in front of you."

"I'm not like that…"

"Sometimes, we don't even know our own hearts."

The intense feeling I'd felt when I first saw her—it was the same as when I'd first met Yeonji. Was this what it meant to desire a woman? Honestly, I wasn't sure.

"You looked at me like that in front of Yeonji, and now you're telling me to hold back… That's impossible."

Her resolve was far stronger than my resistance.

"I knew it the moment I saw you today… that you are my new master."

She knelt before me.

This woman—who owned more than half the shares of the global conglomerate, Choi Han Group, who could have anything she wanted—was now kneeling at my feet.

"Please, become my master."

She pressed her hands together and bowed deeply in a dogeza.

The owner of a global empire was now begging me, a mere man, as a woman.

'This feeling…'

Thump thump thump thump thump

If any other woman had done this, I'd have been flustered and told her to get up. But now, I just stood there, staring down at her. My dick grew even harder, precum leaking as I watched her submission.

"Haa♥"

The precum dripped onto the back of her head, and she trembled with delight.

Swoosh

She raised her head, looking up at me with my dick in front of her face.

"Beee♥…"

She opened her mouth wide, sticking out her tongue.

She was giving me a choice: end things here or stay and become her master.

'I shouldn't… I shouldn't be doing this…'

My mind screamed that this was wrong, but my hand moved on its own, trembling as it reached for her head.

Finally, my hand gripped her hair…

Thump

"Ubuub!?♥"

I shoved my dick into her mouth, forcing it deeper than she could take in one go.

"Ugh! You filthy bitch!!"

Thump! Thump! Thump! Thump!

"Buub♥ Heeub♥ Oob♥ Uheb♥ Heeub♥"

The words spilled out before I could stop them. I grabbed her head, treating her mouth like an onahole, thrusting wildly.

'It feels even better than before!!'

The thrill of dominating her, using her like this, was far more exciting than when she'd been in control. I was on the edge, closer to cumming than ever before.

"You're still sucking my dick even in this situation!!"

"Buub♥ Uub♥ Heeub♥ Buueub♥ Bueeeub♥"

Despite being forced, her face was filled with a lewd smile. She was happy—no, ecstatic—that her choice hadn't been wrong. After 20 years, she was finally being used as a woman again.

Even as I thrust roughly, her tongue worked diligently, licking and sucking with skill.

"How can such a lewd woman be Yeonji's mother!!"

Unlike Yeonji, who was pure and innocent, her mother was a temptress, reveling in her own depravity.

"Ugh! I'm gonna cum!!"

Brrt! Brrt! Brrt! Brrt!

"Uuuuuuuuuuub!?!?♥♥"

I shoved my dick deep into her throat and came. My load was massive, far more than usual, flooding her mouth and throat.

"Ugh♥… Glup♥… Glup♥…"

She trembled, struggling to breathe, but she drank every drop, only a trickle escaping her nose.

"Haaah♥… Cough♥ Cough♥… Beee♥"

"Ugh!"

She opened her mouth, showing me she'd swallowed it all, her face a mix of satisfaction and vulgarity.

Thud

"Haa… Haa…"

"Hehehe♥ As expected, my eyes weren't wrong."

"M-Mother-in-law…"

"It might be awkward at first… but I think you can become my master, Joohyun♥"

While I felt drained, she tidied herself up, a satisfied smile on her face.

"Please take care of me from now on, M.a.s.t.e.r♥"

In the end, I'd agreed to train my mother-in-law as my slave to marry the woman I loved, Yeonji. The absurdity of it all left me feeling hollow, yet there was an undeniable thrill.

I didn't fully understand this feeling, but I knew my life was about to change drastically.

"Okay. Then, I'll take it that you've agreed to my terms. Let's live together here from now on."

"H-Here?! With you, Mother-in-law?!"

"Of course… It's the master's role to keep their slave close and train them♥"

As she gave me that seductive smile, I had no choice but to nod.
