Mom's New Master
'What am I doing right now? Doing this in front of my son... hah♥'
I've held it in for nine long years.
When I learned that my husband had erectile dysfunction, I could no longer receive his training.
Even so, I raised our two adorable children as their mother.
Two sweet kids I'd nurtured with love, separate from the sex slave I used to be.
I've spent happy times just watching Dohyun and Minjung grow.
After my husband passed away from illness, I was simply their mother.
Alone in the lonely nights, I'd relieve myself with masturbation.
Yet the lewd desire inside me still went unfilled.
During those two years of training under my husband, I discovered exactly when I'd feel true happiness.
"Your nipples got so big, Mom."
"D-don't say that♥"
The hand I'd been using to cover myself fell away at my son's single word.
His son stared straight at my breasts with burning eyes.
Those nipples, clearly erect and painfully visible, were too shameful to bear.
'I know I shouldn't do this to my son♥... but now...'
Five years passed.
I lived as nothing but Mom, not his wife or any sex slave.
While suppressing my own twisted urges, I devoted my life to my kids.
But that too became impossible.
My filthy secrets were trapped inside my late husband's laptop.
Even masturbating and holding myself back while watching those secrets was no longer an option.
As the days dragged on, the mounting frustration of my lewd desires gradually numbed my reason.
'Sorry, son♥'
I'd started feeling my son as a man... as a male... only about a month ago.
Drunk, I staggered home.
My son caught me in his arms.
Since becoming an adult, we'd never once had skinship of any kind.
I knew my son was stronger and more muscular than average because he worked as a bodyguard.
But the body I felt against my skin was far beyond what I'd imagined.
His firm biceps, his big and rough hands.
With both, he made me feel my son as a man.
He'd simply carried the tired Mom to her room.
Yet in that moment, I finally understood, after so many years, that I was an ost.
If my son were to cover me right now...
I'd be unable to resist him in the slightest.
Crushed beneath his strength, I'd be forced to become a female, not a mother.
Of course, my son would never do such a thing.
Naturally, he laid me on the bed and quietly left the room.
But from that instant, I began to see my son as a male.
Crushed beneath his massive frame,
Yielding to his strength until my knees buckled,
With the vision of my son looking down at me while condemning his mother—
The lewd fantasy wouldn't leave my mind.
The masturbation I'd done remembering my husband quickly changed into thoughts of my son.
- Ooooh♥ Ah, my son's cock♥ Master’s cock♥ Oooooh♥♥
In my fantasy, I was being raped by my son while making shameless sounds.
Overwhelmed by the maddening urge, I couldn't stop touching myself.
After I finished, waves of guilt crashed over me and I couldn't even lift my head.
And I still wasn't satisfied.
"Your breasts are so huge and pretty, nipples and all."
"Th-thank you♥"
Even this praise made my body tremble with joy.
My pussy grew soaking wet from the filthy compliment.
'Already this wet...'
If I'd been standing, it would have slid down my thighs.
Yet I could already feel it soaking through my skirt and even the couch.
My lewd, expectant pussy facing a male.
Seeing my son in this state made me unable to meet his eyes from shame.
"Are you really okay?"
"..."
If I answered "no," my son would probably stop here.
It could be the last chance to return to normal mother-son.
But...
"...Mom."
Swish...
"Hng♥"
My refusal was taken as consent by my son.
He placed a hand on my thigh and stroked it gently.
The one who had created this situation wasn't my son—me.
I'd known for a long time that my son looked at my hips and chest when he saw me.
When I was younger, I even received a confession of love.
'Now those are just memories♥'
As a mother, I could never have accepted it.
After puberty, my son's gaze became quite explicit.
My body would shiver from the way he scanned me.
But I never did anything more.
Accepting the full mother-son relationship, I gradually grew closer to normal.
Even unconsciously, my gaze at my mother's body could be excused as childish affection.
Before I started seeing my son as a male.
"Keep your hands behind your back until I give permission."
"...Yes♥"
Swish...
I couldn't refuse my son's command.
With both hands behind my back, I gripped my own wrists tightly.
Posing in a way that thrust my chest even further forward.
As if trying to make my nipples stand out more.
"This was started by Mom."
"Y-yes♥"
Just as my son said, I was the one who began this.
Before my husband died, the laptop and the slave contract and the slave transfer document.
At first, I told my husband it was nonsense.
Even so, transferring my son as a sex slave was unthinkable.
My husband said it was the only way for him to be happy before he died.
But I refused until the very end.
That moment, I was refusing as a mother, not his sex slave.
He said he'd understand, but asked me to keep the papers in the file.
I reluctantly put them in a box and kept them safe even after he passed.
'My husband was right♥'
In the end, the one who couldn't hold back and pulled out the transfer document wasn't my son—me.
It was just a piece of paper with no legal power.
But on that paper lay my fate.
I worried endlessly about how my son would react if he saw it.
Would he see me as a plain mother and refuse?
Would our relationship become awkward?
At worst, I'd have to leave the house.
But my son signed his name right next to mine on the transfer document.
He chose to make me a sex slave as his mother.
When I saw the transfer document in the morning, I was excited enough to nearly faint.
With trembling hands, I signed right next to my thumb and set it down.
My son might notice and understand.
And our relationship would completely change.
Even knowing that, I chose it myself.
Just as my husband said.
To become the sex slave of a new master.
"Do you know how lewd your mom's chest is?"
"Y-yes, saying that to Mom♥... hah♥... hah♥"
My heart pounded wildly at my son's blunt words.
His gaze that looked at me as Mom, no, as a female.
Just that gaze alone made my body tremble.
My body was already obeying my son's command as if everything was prepared.
Yet my reason still hadn't accepted the situation.
But it was already too late.
"Mom."
Swish... thud
"Huuuh?!?♥♥"
My son's hand reached forward and grabbed my breast.
A larger, softer breast than anyone else's.
It had become my son's toy and was being touched right now.
"Haaah♥ Euh♥ Hah♥... hng♥"
"Mom's breasts are incredibly soft. So big. And so warm."
"D-Dohyun♥ uuuuh♥♥"
His grip tightened as if he was nervous.
Every time he squeezed, my breast distorted.
He was gripping it hard enough to hurt an ordinary woman.
But the sounds coming from my mouth were nothing but the moans of an aroused female.
"Hah♥ Hng♥ Haaah♥"
"Are you feeling good, Mom?"
"I-I don't know♥"
There was no way I could say it honestly.
Mom making lewd sounds while my son touched her breasts.
Yet this was the first time I'd felt a male's touch in so long.
Because it was my son's hand, the arousal was several times stronger.
'I'm going to cum just from my breasts♥ I have to hold back♥ but I can't cum for my son♥'
My overly sensitive body ignored all words.
Overwhelmed by the intense pleasure, I didn't know what to do.
After two years of training, I became a perfect bitch.
But after nine years of rest, the sensation had dulled.
"This area is so big too."
Thud
"Oooooh!?♥♥♥"
When he pinched and tugged my nipple, overwhelming pleasure surged through me.
The pleasure I'd never felt even while masturbating alone covered my entire body.
'I-I'm cumming♥ My son's hand made me cum♥'
A fierce wave of arousal hit me from behind.
Even just the fact that I climaxed under his hand sent waves of sensation I'd never experienced before crashing over me.
"C-cumming ooooooh?!?♥♥"
Pshuuuush
"Eh, eh?"
My son looked startled too and pulled his hand away.
He was probably shocked that such lewd fluid suddenly shot out.
"Ooh♥... ooh♥"
It was the real orgasm I'd felt in a very long time.
Unable to stop my hips from twitching.
My vision turned completely white, then slowly returned.
"So this is what it means to cum."
"Ah♥"
When reason returned, I could see what I'd just done.
Lewd fluid had shot out and soiled my son's pants.
I'd climaxed just from my breasts, completely abandoning my mother's dignity to become a single female.
"But I never told you to let go."
"Eh? S-sorry♥ Mom didn't even realize."
The moment I came, my hand unconsciously released.
I grabbed the couch and my son's arm to somehow calm my thrashing body.
"Am I your sex slave, son?"
His question left me breathless.
An incestuous relationship I shouldn't have.
But I had just realized it clearly.
"...Yes, I am♥"
My son... this man was my new master...
——
My heart pounded wildly.
I roughly groped my mother's breasts.
The large breasts that my own hands were distorting.
I couldn't take my eyes off the stiff nipples.
'This is the scent of Mom... of a female.'
Just the scent made something inside me stir.
The gentle mother who only ever treated me as her son.
Now she looked at me with an expression of climax, of a female.
An expression of wanting more, of longing.
One of my father's videos flashed through my mind.
"You can't let the master get his pants dirty, Mom!"
"S-sorry♥ Mom couldn't hold back and came so I apologize♥"
I raised my voice pretending to be angry, and Mom flinched.
It might look like fear, but it wasn't.
Mom was excited right now.
An aroused female happy to be scolded and insulted by a male.
"Take off your clothes and get on the table in the waiting position."
"Th-that's♥"
"Hurry."
"Y-yes♥"
I didn't need to explain further.
Mom already knew.
With trembling hands, she began to undress.
"Swallow..."
My first time ever seeing my mother's naked body.
Today I was seeing it for the first time.
Slither...
'Beautiful.'
Seeing my mother's naked body that excited a male, I stripped without hesitation.
Feeling that what was in front of me was no longer Mom but my sex slave..
