I Became My Mother-in-Law's Master
"Mmph♥ Slurp♥ Hah-mph♥ Gulp♥"
"Ugh! M-Mother-in-law!!"
I had come to pay my respects and formally ask for her blessing to marry her daughter, but right now, I was having my cock sucked by my mother-in-law.
'W-what is this incredible technique!!'
She wasn't just taking my thick cock into her wide-open mouth; she was using her throat to swallow more than half of it, her tongue working tirelessly to stimulate the shaft and the glans.
'Are you really someone who hasn't sucked a cock in twenty years!?'
"Hah-mph♥ Hehehe♥ It seems my new Master likes my blowjob, too♥"
Noticing that I was pleased by the reaction of my cock, my mother-in-law looked up at me with an obscene smile.
'That expression... it's just like Yeonji's...'
To be precise, it was the expression Yeonji made when she was aroused—like a female in heat, with flushed cheeks and a gaze that looked at me not as a man, but as a stud. They gave off such a similar vibe that one could easily say mother and daughter were two peas in a pod.
"Since we're still just at the 'greeting' stage, I'm taking it easy, but... does it feel better than with Yeonji?"
"T-that is..."
"Lick♥"
"Ugh!"
To be honest, it felt so good it couldn't even be compared to Yeonji. Until now, I had only known Yeonji, and she had only known me. Because we were each other's firsts, our sexual technique was, frankly, very lacking.
"Yeonji is practically a novice at this, so she'd probably find it difficult even just to hold a cock in her mouth♥... Like this, for example♥"
"S-so deep... Ugh!!"
This time, she took my cock into her mouth and swallowed it whole, wrapping her mouth and throat around it almost to the very base.
"Puh-hah♥... Even for me, it's hard to swallow all of such a long, thick cock♥"
My mother-in-law was showcasing a technique that was in a different league from Yeonji's. The gentle, aristocratic lady vibe she had projected earlier was nowhere to be found; only an obscene temptress remained, seducing a male.
"How is it?.... Please, tell me honestly♥ Hah-mph♥ Slurp♥"
"M-Mother-in-law, it feels better!"
"Hehehe♥ Thank you, Master♥"
"Hngh!?"
Seeing my mother-in-law call me Master with that lewd smile, the male instinct I had been suppressing within me began to awaken.
'N-no!! I can't do something so twisted to my mother-in-law!!'
I had already heard an absurd marriage condition from her, and even though I was currently being sucked off, my reason hadn't completely crumbled yet.
'I have to find a way to make things normal again!'
I had made up my mind to love only Yeonji for the rest of my life. To mix bodies with another woman—and my mother-in-law at that—and become her Master? This was a massive betrayal of Yeonji.
"M-Mother-in-law, stop!"
"Hueh♥... Is something uncomfortable?"
"Y-you shouldn't be doing things like this! Let's just pretend I didn't hear that part about becoming your Master, and let's just—"
"Hooo..."
At my resistance, my mother-in-law made a slightly disappointed face and wiped her mouth.
"It seems Juhyun-ssi still doesn't quite understand..."
"Yes?"
"If I were to ask Yeonji to choose between you and me... who do you think she would choose?"
"That would be... Mother-in-law... I'm sure."
Yeonji's love for me was genuine, but considering her character, she would never be able to abandon her own mother. Even if she did abandon me...
"That's right... And if I put my mind to it, I could keep you and Yeonji apart for the rest of your lives, making it so you could never meet again."
"No, there's no need to go that far..."
"You might think it's too much, but... I no longer have the patience to endure."
My mother-in-law clutched her own breasts and stared at me.
"Ever since I heard that you were dating Yeonji a year ago, I've been waiting and enduring, dreaming of the person who would become my new Master."
I thought she was being sincere, but that was my mistake.
"My body is waiting to be wanted, to be obeyed, to be submitted to, to be dominated, to be trained, and to become miserable and wretched."
My mother-in-law spat out words that were close to a scream in a low voice.
"I endured for over twenty years, trapped by my husband's commands, unable to satisfy a single one of my desires."
She approached me once more.
"You are my only savior now... If you refuse my proposal... I will have Yeonji marry another man... Someone who will accept my terms."
"No!! Yeonji with another man... Argh!!"
Hearing words that made my blood boil just by imagining it, I jumped to my feet and glared down at her.
"That's the look... You had that same look when you first saw me earlier... The look of a male wanting to claim the female right in front of him."
"I didn't mean to..."
"Often, one doesn't even know their own heart..."
The intense feeling I had when I first saw her. It was the same feeling I had when I first saw Yeonji. Was this the feeling of wanting to claim a female? Honestly, even I didn't fully understand what this emotion was.
"You looked at me with those eyes in front of Yeonji, and now you tell me to endure? That's impossible."
Her desire was far stronger—incomparably stronger—than my urge to resist.
"I only saw you for the first time today, Juhyun-ssi, but I was certain... that you were my new Master..."
My mother-in-law knelt before me.
A woman who owned more than half the shares of the Choi Han Group, a global corporation—a woman who could have anything she wanted—was now kneeling before me.
"Please, become my Master."
And then, she folded her hands politely and performed a dogeza.
The de facto owner of a global corporation was begging a male, simply as a female.
'This feeling...'
Thump, thump, thump, thump, thump.
If a woman had shown me this in the past, I would have been flustered and told her to get up. But now, I just stood still, looking down at her. Moreover, seeing my mother-in-law in that position, my cock was leaking precum and becoming even harder.
"Haa♥"
The precum dripped onto the back of her head, and as she felt it, my mother-in-law shuddered with joy.
Swoosh.
She lifted her head and looked up at me from in front of my cock.
"Blehh♥..."
She opened her mouth wide and stuck out her tongue. She was giving me the choice. Whether to end it here as I said before, or to remain in this position as her Master...
'I shouldn't... I really shouldn't...'
My brain knew it was wrong, but my hands were slowly moving toward her head. My hands, trembling as if trying to resist, finally grabbed her hair...
Thrust.
"Mmph-mph!?♥"
I shoved my cock into her mouth. I forced it in, past the point she couldn't swallow earlier, and made her take it all the way to the root.
"Argh! You lewd little bitch!!"
Thrust! Thrust! Thrust! Thrust!
"Mmph♥ Hmph♥ Oh-mph♥ Ugh-mph♥ Hmph♥"
The words slipped out before I could stop them. I held her head, using her mouth like an onahole, and shook her violently, forcing her to perform oral sex.
'This feels even better than before!!'
Compared to when she was leading and sucking my cock, the situation of forcibly using her as an onahole and thrusting roughly was infinitely more exciting. I was so aroused that I felt like I was on the verge of ejaculating.
"Are you still sucking it even in this situation!!"
"Mmph♥ Mmph♥ Hmph♥ Mmph♥ Mmmph♥"
Even though I was forcing her, her face was filled with an obscene smile. The joy of knowing her choice hadn't been wrong, and the happiness of being used as a female for the first time in twenty years. Even though she was being used against her will, she didn't stop licking my cock, and her face, as she sucked with such intensity that her cheeks were hollowing out, looked just like a sow in heat.
"How can such a lewd woman be Yeonji's mother!!"
Unlike Yeonji, who was overflowing with innocence and purity, my mother-in-law was praising my cock and rejoicing. They might have looked similar in appearance and body, but Yeonji was never this lewd.
"Argh! I'm cumming!!"
Splurt! Splurt! Splurt! Splurt!
"Mmmmmmph!?!?♥♥"
I thrust my cock deep into her throat and ejaculated. I was someone who boasted a volume of semen several times higher than the average man, but this was a record-breaking amount, flooding her throat.
"Mmph♥... Gulp♥... Gulp♥..."
Perhaps because she couldn't breathe, she trembled, but she didn't stop swallowing, and she succeeded in drinking almost every drop.
Drip.
However, the semen she couldn't finish trickled out of her nose, making her composed face look incredibly vulgar.
"Puh-haaa♥... *Cough*♥ *Cough*♥... Blehh♥"
"Kuh!"
Seeing me, who had shoved my cock into her mouth until she couldn't breathe and berated her with harsh words, my mother-in-law smiled and opened her mouth to show me she had swallowed it all.
Thump.
"Haa... Haa..."
"Hehehe♥ My eyes didn't deceive me after all."
"M-Mother-in-law..."
"It might be awkward and difficult since it's your first time... but if it's you, Juhyun-ssi, I know you can be my Master♥"
Unlike me, who felt as if all the strength had drained from my body, my mother-in-law smiled with satisfaction as she tidied her clothes and face.
"I look forward to working with you. Mas.ter.♥"
I had ended up training my mother-in-law as a slave to marry the Yeonji I loved. While I felt a sense of hollowness at this absurd situation, there was a thumping in my chest from another side. I didn't know the nature of this feeling yet, but I knew my life was about to change drastically.
"Good. Then, I'll take that as your agreement. Let's live together here from now on."
"H-here?! With you, Mother-in-law?!"
"Of course... keeping a slave by one's side to train them is the role of a Master, after all♥"
Seeing my mother-in-law's bewitching smile, I realized I had no choice but to nod.
