"Seong-ah, why do you think I made this device?"
"Um... You made it to help me practice serving you, Master. You made it yourself for me."
"Right? You understand that well, don't you?"
"Yes? Yes..."
He wanted to ask how she could act so disappointingly while understanding that.
Jun-ha kept his poker face, but smiled gently as he continued.
"I definitely taught you how to serve, didn’t I? That when serving my cock, you have to pay attention to both ends, always."
"Ah... yes..! I remember!"
From the very tip of the glans to the very base at the root
Whether it’s the mouth, pussy, or ass, whichever hole is being used, I taught you to always stimulate from 'end to end' during thrusting.
"But, Seong-ah, did you do it that way even though you knew?"
"Yes..?"
What does he mean by that?
"I thought I did well..."
It wasn’t an excuse said without thought.
She had been lowering her hips to the base of the dildo; they’d watched that part on TV together over a dozen times.
Everything seemed fine...
Why is he picking at something again?
With a scared look, Seong-ah fidgeted with her fingers.
"Watch closely."
The vulgar video played again.
Aaaah!! Aaang!!
In the video, Seong-ah bounced her hips up and down, letting out lewd moans, her breasts shaking. She pressed the dildo’s button correctly.
But...
On closer inspection, the dildo didn’t come all the way out to the tip.
The first ten reps or so were correct, but as time passed, her range of motion shrank as her legs tired. By the end, she was barely moving a third of the way up and down.
"Now do you get it?"
"Ah... auhk..."
For the counter to advance, she had to press the button at the base and then come up so the sensor at the tip was completely outside.
She pressed the button but ignored the sensor so naturally, the reps didn’t count.
"Sigh, if you can’t even do something this simple, what am I supposed to tell you to do?"
"Hhic..!"
Seong-ah hadn’t properly performed the assignment her master gave her.
Even if she ended up suffering severe punishment for this, she shouldn’t feel it was unfair.
"Ah... I’m sorry, Master..! I didn’t know..!"
Admitting her mistake, she bowed low, naked, in dogeza.
"Okay, I get it. Well... if you think about it, it’s only natural. Even doing 100 squats without a dildo would be hard, right?"
"Hhic..."
To pull that massive dildo all the way out to the tip, she had to deeply squat with her knees bent 90 degrees.
Even for someone who exercises their legs, it’s a demanding posture, so Jun-ha decided to let it go with a smile.
But...
Asking for forgiveness for not doing as told only applied to humans.
"Seong-ah, you know you shouldn’t do that, right?"
"Hhic.!!"
"What are you?"
"I... I’m female livestock..."
"Not that."
"Hhuu... I’m Master’s cunt, onahole, cock case..."
Even being called female livestock was too generous for such disobedience.
She was correctly nothing more than a disposal item to bring a man pleasure.
"Right? You know you have no rights, and when it’s sex, you’re supposed to be used like a tool, aren’t you?"
"Yes..."
Cunt, onahole, cock case.
Fitting those names, Seong-ah was supposed to be used as a tool without will of her own during sex.
She had to ride on top, moving herself so the master didn’t have to, and despite rough, violent treatment, she had to show a happy face and moan with joy.
"Seong-ah, didn’t I tell you, when you serve me, move like a machine with no emotion?"
"Yes, Master..."
Like a self-moving automatic onahole, Seong-ah had to suppress her own feelings and show only mechanical movements for her master’s pleasure.
Even if it made her go crazy from repeated orgasms dozens or hundreds of times
If Master hadn’t cum yet, her duty was to keep rocking her hips.
"Then why do you keep disappointing me?"
"S-sorry, Master... hic..."
She really tried hard...
She really, really tried...
But seeing her master’s cold indifference still hurt her to the core.
"Just swallow the cock deep, lift up to the glans, and repeat. How hard is that?"
"I’m sorry..."
With her own mistake exposed, ‘I’m sorry’ was all she could say.
"If it’s because your body is sensitive, just tell me and I’ll ask the communal property facility to modify you."
"Ah, no!! It’s okay!! I was wrong, Master!!"
There was even a way to sever all pleasure nerves with drugs and make her frigid.
Livestock who underwent that always wore blank expressions and regretted their lives,
having lost all pleasure from sex and instead feeling unpleasant sensations, like picking their nose.
"I was wrong, Master!!"
The word ‘modification’ made Seong-ah snap to her senses and desperately bow her head.
"Seong-ah, I said I wouldn’t punish you for hiding the counter. But I can’t forgive not doing the training itself properly."
"Hhic..!"
Jun-ha stuck the suction base to the living room floor and called Seong-ah with a nod.
"Come here. I’ll give you another chance do all 100 right this time."
"Yes, Master..!"
Before his mood could change, Seong-ah hastily positioned herself over the dildo, squatting with her hands behind her head.
Revealing her pussy, breasts, armpits, and anus in a shameful posture, she lined up her pussy hole with the tip of the dildo without hesitating.
"Kkeuuuuk..!"
Her holes, already stretched by the urethral and anal plugs, ached with each movement.
Every time the dildo pushed between the two plugs, a shiver ran down her spine.
"Kkaaaaaaang..!"
With half the dildo inserted, she took a deep breath, trying to force her hips down under her own weight but it was still too much.
With no mannequin just the suction cup on the floor she had to plant her butt completely on the floor to press the button.
If she got used to it, she’d learn to bounce her hips for a full range of motion, but with her belly already stuffed, she’d never get used to that huge fake cock.
"Kkeuuuuk.."
Click
The moment she swallowed the dildo and sat down, the button made a satisfying sound.
Gathering strength in her ankles and thighs, she lifted her hips again.
"Kkeuuuuuuuaang..!"
The dildo slipped out little by little, smeared with watery arousal fluid.
Her pussy clung to the dildo, folds rippling and trying to pull it back in.
She barely managed to bring her knees to 90 degrees and get the glans sensor out, but
"Eh..?"
She missed the 30-second window, so the counter didn’t register.
Unable to stand it, Jun-ha approached with a wry grin and clamped her waist from behind.
"You still don’t know how to move right. I’ll show you how to please a man, so watch carefully."
"M-Master... kkak!"
Thud
Gripping her hips hard, he yanked her down onto the dildo to the base.
"Kkaaaaaaaaaak!!"
This time, he lifted her hips up so the dildo was nearly out,
and the moment the counter ticked up, he slammed her back down.
Thud
"Kuuk..!"
Heo Seong-ah drooled with wide eyes, the dildo pounding her womb with such force it took her breath away.
She couldn’t even scream for mercy, only gasp for air as Jun-ha continued to bounce her body up and down.
Thud, thud, thud, thump
"Kkheok! Akk! Uk! Kk..!"
Being held and forcibly slammed like a ragdoll brought unimaginable pain.
Unable to speak properly, her limp limbs just dangled.
"Kuuhk... uh... ak..."
Heo Seong-ah was so light, Jun-ha could bounce her like a package with little effort.
Like handling a tool, he shook her body until the counter hit thirty, then let her go.
"Now you can do it by yourself, right?"
"Kkuek... uuk..."
With the dildo still inside, Heo Seong-ah stretched her legs and trembled violently.
Her blurred, tear-soaked vision struggled to focus, racked by muscle aches like she’d been beaten all over with a hammer.
Her body, at the limit of exhaustion, could no longer muster any strength.
"Wugeuk..."
The massive dildo probing her lower belly pressed at her cervix and twitched
Her body, nearly fainting, clenched the silicone cock and gasped at unwanted pleasure.
"Kkeuuuuk..."
She wanted nothing more than to faint right away
But she couldn’t stay like this.
This was her second chance.
If she didn’t move, she’d be punished for sure.
