The Mother-in-Law's Seduction
I stared at my mother-in-law, dazed, unable to process the meaning of what I had just heard.
"Huhu."
Having just uttered the most absurd thing imaginable, she simply smiled and took a leisurely sip of her tea.
"I-I mean, what on earth are you talking about..."
"Exactly what I said. If you want to marry my daughter, you must train me."
'I’m not losing my mind, am I...'
A mother-in-law telling me to train her if I want to marry her daughter. I’d heard lines in morning soap operas like, "I will never allow this marriage as long as I draw breath!" but I had never heard, "If you want to marry my daughter, train me, your mother-in-law."
The situation was so twisted that even a morning soap opera would look like a wholesome sitcom. My brain simply couldn't function.
"W-why... would you say that?"
I squeezed out the words, trying to calm my racing heart. It was the best I could do.
"I see... that was too sudden, wasn't it?"
"Yes... honestly, I still don't understand what I just heard."
If I had just replied, "Understood, Mother-in-law! I'll start training you right away!" that would have made me the crazy one. My current reaction was the only normal one.
'No, wait. No one has ever experienced this, so I don't even know what "normal" is anymore.'
Caught in a situation so abnormal that I couldn't even tell if my own words made sense, I waited quietly for her to speak again.
"My husband... Yeonji's father... was my Master."
"M-Master... I, I see..."
Thanks to her speaking of such a deep family secret so casually, my head was spinning. Still, I braced myself to keep listening.
"Others might say it was just the passion of youth, but my husband and I truly, deeply loved each other..."
A small smile graced her lips as if she were reminiscing about those days.
"It was a relationship between a Master and a Slave who truly cherished one another."
'No, this is impossible! How am I supposed to focus on anything else!'
As a normal love story suddenly morphed into something straight out of an adult manga, my head began to swim.
"Then, when I was pregnant with Yeonji, my husband passed away. Along with my father-in-law..."
"Ah... don't tell me, that incident..."
It was an event that had shaken the entire country, even I knew of it. The plane crash involving the Chairman of Choi Han Group and his successor. The cause was sudden turbulence—literally just a stroke of terrible, unlucky fate.
"With my father-in-law and husband dead, I inherited vast wealth and company shares, so raising Yeonji wasn't a problem. But... the biggest problem was me."
Her eyes filled with sadness, but she forced a smile, pretending to be fine.
"A body once trained by a Master... if I couldn't find release through masturbation even for a single day, I couldn't endure it. I had become a hopeless, lewd masochist."
"I-I see..."
I truly didn't know how to respond to that. Nodding was the best I could do.
"My husband... my Master is gone, but his commands remain absolute to me. Do not sleep with any other man besides your Master, and do not create another Master... I have kept these commands until now."
The relationship between my mother-in-law and her late husband had truly been one of master and servant. It might be hard for an ordinary person to understand, but I could tell she was sincere.
"You remember what I said about the Master's commands being absolute, right? It was something he said as a joke three months before he died."
"Ah... yes..."
"He looked at my pregnant belly and said... 'If I die, make my son-in-law your new Master.'"
'This guy was seriously insane.'
Even if he said it as a joke, it was effectively permission to serve her son-in-law as her new Master. Of course, he didn't know he was actually going to die, and my mother-in-law had brushed it off as a joke at the time, but...
"For the past year, I have truly endured... waiting for a new Master to appear.♥"
The way she looked at me changed. Until a moment ago, it was just the look of a mother-in-law looking at her son-in-law...
'Gulp... something about this... is erotic...'
Now, it was the look of someone gazing at a being superior to themselves. It was a gaze so thick with lust that just being looked at made me feel aroused.
"For twenty years, I have truly endured for Yeonji's sake... to the point where I didn't even think about the playful words my husband left behind. But..."
She stood up and came to my side... kneeling on the floor, not the sofa.
"M-Mother-in-law, w-wait, what are you doing!?"
I tried to stop her, but she was faster, placing her hand on my crotch.
"When I realized you were Yeonji's boyfriend and that you truly wanted to marry her, the 'former Master's' playful command came back to me."
As I looked down at her, her face slightly flushed, her massive breasts caught my eye.
'Are they... bigger than Yeonji's?... Gulp...'
Breasts so large they couldn't be fully contained by the dress she was wearing. If an ordinary woman wore it, the chest area would be loose, revealing a bit of cleavage, but on her, the dress looked like it was about to burst.
"I've endured for over twenty years... but ever since you appeared, the instinct of a female that I had barely suppressed began to awaken.♥"
"Ugh!... M-Mother-in-law..."
Even as I tried to resist, I couldn't bring myself to push away her lewd appearance and touch.
"The one I will serve as Master♥... the Dominator who will liberate all the instincts I've kept suppressed until now.♥"
She had been a gentle and elegant woman, but now she felt like a lustful prostitute.
"It seems you don't dislike me either, Juhyun.♥"
"T-this is just a biological reflex... ugh!"
I had gotten an erection without realizing it, and I tried to make an excuse, but as her touch grew faster, a moan escaped my lips.
'S-she's skilled! Much more than Yeonji... ugh!'
It felt wrong to compare her to Yeonji, but Yeonji was the only woman I had ever experienced. Because of that, compared to her, my mother-in-law's touch was on a different level.
"You look like you're struggling.♥..."
Zzzzip.
"Ah... M-Mother-in-law..."
"It's... amazing.♥"
More aroused than I was, she pulled down my zipper and finally brought out the penis of the man who would become her son-in-law.
"I'm sorry to say this, but... it's so much bigger... than my late husband's.♥"
She stared at my 22cm-long, thick member. Even as she felt a pang of guilt toward her former Master and late husband, she wore a rapturous smile, gazing at the member she would serve from now on.
"It grew this big because of me, didn't it?♥"
"T-that is..."
"Where were you looking? Was it because of the dress I wore on purpose to show off my breasts?"
'On purpose...'
She had intended to seduce her son-in-law from the very beginning, wearing that dress with a specific goal in mind.
"Or was it... because of my panties that I showed you ever so slightly?♥"
Swoosh.
"Hup!!!"
I covered my mouth with my hand to stifle a shout.
'Are you crazy!? You wore underwear like that in front of your son-in-law!?'
She remained in a crouching position, legs spread wide. The panties she was wearing were made of mesh, and I could see her pussy clearly through them.
'Shaved... and besides... is it... wet!?'
I couldn't take my eyes off her, staring with wide eyes at the state of her pussy, which was impossible to believe was being shown to a son-in-law.
"Hahaha♥ How is it? My. Pus. Sy."
Swoosh.
"M-Mother-in-law... i-if you do this... Gulp!"
Noticing that I liked it, she braced herself with her arms and pushed her pussy further forward.
"Ha-eu-eu♥ To strike a pose like this in front of a male...♥ It's been so long.♥"
She had kept her chastity for over twenty years, and now she was getting aroused by showing her hidden, intimate parts.
'It's... getting even wetter!!'
She was becoming more and more aroused as she showed me her see-through panties. Seeing them grow wetter, my penis became fully erect, revealing its full majesty.
"Haa♥... I was enjoying myself all alone, ignoring the new Master I'm to serve.♥"
Every word she spoke stimulated the male in me. The phrase "new Master" was awakening the male instincts I had suppressed deep inside.
'No, this is wrong! I have Yeonji, and I'm supposed to train my mother-in-law!? This is absolutely forbidden!'
I thought about escaping this soap-opera-level situation, but my body wouldn't listen.
She came back in front of me and reached out toward my member. As her soft hand wrapped around it, my body was engulfed in a wave of arousal so intense it felt like a sin.
"Hahaha♥ It seems your member likes my pussy too.♥... To grow so proudly...♥ Hooo~"
"Ugh!?"
She had only blown a light breath on it, but my penis twitched, welcoming the female.
"You haven't... done it with my daughter yet, have you?"
"What!? H-how did you..."
"Yeonji doesn't hide anything from me... Don't worry. No one knows but me..."
Since Yeonji had consulted her about sex multiple times, she knew everything about our relationship.
"To be so proud and yet not know a female... Poor member.♥ *Kiss*"
"Haa... haa... M-Mother-in-law..."
She kissed the glans as if she felt sorry for it. One might think it was unclean since I hadn't washed, but there wasn't a hint of disgust on her face.
"I will teach you about women... about females.♥ So, taste me slowly and decide.♥ Ha-up♥"
"Ugh!? M-Mother-in-law!!"
Before I could even say a word, she wore a lewd smile, opened her mouth, and took my member inside.
