Episode 153: M0m Is a Pet Dog 

"Haa... haa..." 

Seo Na-yeon shuddered as she felt warm liquid flood into her rectum. 

It wasn’t just the stimulation of an erogenous zone. 

She’d just had incestuous se.x with her s0n. 

No matter how much she tried to justify it by saying it wasn’t vagin.al se.x, the fact that she’d offered her anus to satisfy her s0n’s lust couldn’t be erased. 

‘I did it with Hyun-sung again... and I was the one who asked for it this time... ah.’ 

She’d even begged her s0n to take her, unable to resist her own lust. 

Unlike the first time, when her s0n had roughly taken her, this time it was her own desire that drove her. 

The psychological thrill of such forbidden, depraved pleasure made her body burn. 

Even after cu.mming twice, Hyun-sung showed no sign of cooling down, holding her tightly and whispering excitedly. 

"Haa... haa... M0m, M0m..." 

"Y-yeah..." 

"Did you like it too? Hm?" 

"...Yeah." 

"Haa... haa... I love it, M0m." 

They didn’t say "I love you," but their embrace and whispers were no different from lovers. 

At some point, her s0n had started treating her as a woman, as a female. 

She trembled  

feeling the ominous weight of a great sin, but also the corrupt pleasure of a forbidden relationship. 

===== 

Back to the present  

I fiddled with M0m’s anal plug and spoke. 

"Remember that day? I fu.cked you three times in a row in the bathroom. You totally lost it and cried and everything, haha." 

"You..." 

After that day, 

I started training my m0m. 

My own birth m0ther. 

 Put your arms above your head and ride the dildo yourself. 

I’d stick a dildo in the floor and make her sit on it, moving her hips herself. 

 Look at the camera and make a se.xy face. Good... now suck. 

I’d make her suck my cock on the floor and film her humiliating expression. 

 I’ll eat your pu$$y... good... now, here I go. 

I’d 69 her, forcing my cock into her m0uth while I licked her pu$$y. 

Driven mad by the thrill of perverse taboo, I tormented M0m in every way I could whenever we were alone. 

I kept pushing the limits of SM play with her body. 

At first, it was just weak dildos and vibrators for stimulation, 

then bondage and spanking humiliation. 

I’d even make her masturbate in front of me  

with a vibe, with her fingers, with her ass. 

I filmed her humiliating herself in all sorts of ways on my orders. 

And always, during SM play, I made her call me "Master." 

She was so slow to learn it took almost ten days. 

Oh, and I fu.cked her a$$twice a day, every day. 

It was all just for my own arousal  

a convenient anal slave for my lust. 

That was how I treated M0m. 

So I ordered her to always wear an anal plug. 

Whenever Mi-hyun was out, I’d use any chance to fu.ck her ass. 

Sometimes  

"Ah, it hurts, Hyun-sung!" 

"Tch! Deal with it. You said you don’t want vagin.al se.x, right? Changed your mind?" 

"Ugh..." 

She always seemed like she wanted me to fu.ck her pu$$y instead, but her last bit of pride kept her from saying it. 

Anyone could see she was begging to be f0rced, but she wouldn’t say it herself. 

So for two weeks, I kept fu.cking her ass. 

At first, it was 70% pain, 30% pleasure, 

but lately, maybe thanks to the plug, her sphincter loosened up and the ratio flipped. 

She still complained, but her moans got wilder and wilder. 

Even as I tormented her, she enjoyed it  

maybe that’s a kind of filial piety? 

Anyway, after two weeks, 

M0m was tamed. 

Like a loyal bitch. 

I pulled on the plug in her ass, watching her loose but still tight hole follow with it. 

"Good. You’re obedient, huh?" 

"Ugh... only because you made me..." 

"Gwak Young-chul never made you do this... how does it feel to be f0rced by your s0n?" 

"You’re too much..." 

"Me? Really?" 

"Yeah... forcing me to wear this... ah!" 

"Come on. You promised me, remember? You said I could use your body however I wanted for my lust." 

"T-that was..." 

When she pouted, I played a video I’d recorded on my phone. 

I think it was about a week ago. 

That day, I tied her up and spent a couple hours getting her worked up. 

It was a repeat of the first play, but this time I used nipple clamps too. 

In the video, M0m was tied with her hands behind her back, legs spread wide in an M-shape, being tortured to the brink of madness. 

She was totally gone. 

 So, what do you say? What will you do for your Master? 

 U-use my body... however you want, Master... 

 Be specific. 

 Please fu.ck my ass... and my m0uth too... ah! Ah! 

 You really want to fu.ck your own s0n? Say it. 

 I want it, Master... ah! Hngh! 

The video ended with M0m squirting all over the camera. 

"See? You promised. You wanted your a$$and m0uth used, right?" 

"T-that’s... only because you tormented me so much..." 

"So, do you hate it?" ... "..." 

"Do you? Should I stop?" 

She still had a shred of pride left didn’t want to beg. 

But I’d already seen her pu$$y dripping as she listened to me fu.ck So-hye, so I knew she was a depraved bitch who wanted my cock in her ass. 

SMACK! 

I spanked her blushing a$$for a less0n. 

"Hngh!" 

"Heh. Want me to fu.ck you while Mi-hyun’s in the shower?" 

"...Yeah." 

"Say it properly." 

"...Please fu.ck me, Master..." 

"Where should I fu.ck you?" 

"...I stretched my asshole for you, Master." 

It wasn’t just about using her body  

I wanted to conquer her mind, too. 

Now I understood why Gwak Young-chul and Dad treated her the way they did, as I roughly pulled out her anal plug. 

"Hngh!" 

"Good. You put in plenty of lube, right?" 

"Y-yes..." 

Her hole gaped open from the shock, lube already leaking out. 

And M0m... 

"Haa... haa..." 

She looked to her new "Master" for se.xual reward, 

bending over like a loyal bitch, shaking her plump a$$for me. 

Ah. 

To think such a filthy bitch was my m0m. 

A mix of pity and affection  

I wanted to fu.ck her right away, but held back and took out a new "toy." 

"Here. Put this on." 

"...W-what’s this?" 

"A dog collar." 

I fastened the collar around her neck. 

===== 

"While you’re wearing this, you’re a bitch. Got it?" 

"Y-yes..." 

SMACK! 

"Ah!" 

"Do you know why you’re being punished?" 

"Because I didn’t call you Master?" 

"No. What did I just say?" 

"...You called me a bitch." 

"No, not just a bitch be a real bitch. Got it?" 

"...O-okay?" 

SMACK! 

She was slow to learn, so I spanked her again with a switch. 

"With this on, you’re a bitch. You can’t speak like a human, and you can’t walk on two legs." 

"...Huh?" 

"From now on, you just bark. Got it?" 

Honestly, being fu.cked in the a$$or trained with a vibrator was less humiliating than this. 

Being treated like a real dog by her s0n  

M0m couldn’t hide her expression. 

But that’s the pleasure of training  

feeling humiliation, and yet wanting to obey, letting go of her humanity and becoming a tool for her Master’s lust. 

I was too impatient to do proper step-by-step training and just fu.cked her hard at first, 

but this kind of gradual conditioning is the essence of SM play. 

In the end, M0m gave in. 

"...Woof, woof!" 

She gave up her pride as a human and barked like a real dog, wearing a collar. 

Even training a regular girlfriend to your taste brings a rush of taboo and conquest  

but making your own m0ther into a "dog" at your command, 

the pleasure of destroying all ethics and boundaries... 

It possessed me, and I wanted more. 

More stimulation. 

More sadism  

"Okay... before Mi-hyun finishes her shower, I’ll fu.ck you in the living room. Squeeze your a$$tight and cu.m quick, or Mi-hyun will catch us. You don’t want your daughter to despise you too, right?" 

M0m’s face turned pale at my threat.
