Master’s cock was still far too much for her inexperience to handle.
But if she wanted to avoid punishment, she had to do it.
Kkhaeuuk..!
Slowly.
So it wouldn’t hurt.
She lowered her hips in a slow motion and swallowed the dildo.
Kkeuuuk..!
She felt the dildo, stretching her inner folds, bump against her cervix.
The chilling sense of being pierced made her feel like her life was in danger, but the problem was the dildo’s switch still hadn’t been pressed.
Huuu... Huuu...
Glancing down, she estimated there was still about 3cm to go.
Determined to get it all the way to the base, she forced her hips farther down.
Kkeuuuuuk..!
Just 3cm left.
It seemed like she could do it with a little more effort,
but her pussy had reached its limit and wouldn’t move another millimeter.
Kkhua... haa...
Honestly, even this was dangerous.
The pressure mashing her cervix made her legs tremble.
With plugs stuffed in her urethra and rectum as well, her whole lower belly vibrated with a sickening sensation.
Kkeuuuuuk..!
What if she forced it and the dildo punctured her uterus... or something went horribly wrong?
Even imagining it was terrifying.
But she still had to do it.
Had to...
Hic..!
She took a deep breath and tried to push her hips down,
but the clear bulge of the dildo under her belly filled her with fear.
Huu... huu...
This was definitely dangerous.
It was still too much to take all of Master’s cock.
But at least where she’d only managed half at first, now she could take all but the last bit.
Wasn’t that already worthy of praise?
Huu...
Heo Seong-ah thought of Jun-ha.
If Master were here, how would he react?
...
...
...
He’d probably make her shove the dildo all the way in by force.
Ah... aaaaaaah..!!
She didn’t need to hesitate anymore.
Relaxing her legs and shifting her weight back, she dropped her hips and swallowed the dildo to the base.
Kkhaaaaaaaaaak..!
The shockingly sharp pain took her breath away.
Her back arched and her fingers and toes twisted in reflex.
Kkhaaaaaaaaaaaaaak..!
It hurt so much she thought she’d die, but a woman’s genitals are surprisingly resilient.
No matter how painful, a dildo this size wouldn’t really hurt her.
Click.
The suction cup at the base hit her clit and triggered the button.
Now she just had to lift herself up again, but her legs were too weak.
Kkeuuuuuuuk!!
There was no time to stall.
She had 30 seconds from pressing the button to get the tip’s sensor all the way out.
Huuu... huuu... kkeuuuuuuuuk..!
Planting her hands on the mannequin’s chest, she used her upper body’s momentum to raise her hips.
The thick dildo slid out, catching at her opening,
and finally the green sensor flashed and the counter ticked up by one.
Kkhaaaaang..!
Her legs gave out and she dropped back down, swallowing the dildo deep again.
Her elastic pussy quickly returned to shape, radiating a fresh ache.
Kkaaak..!
Unless she forced her weight down, it would never go in all the way.
So once again, the button wasn’t pressed.
Shaking and upright, she made sure to thrust her pelvis down and press the button before the 30 seconds ran out.
Click.
Kkeuuuuuuuk..!
Right after, she pulled her hips up to the tip and slammed back down.
Nuehaaaaa...
Each round left her more exhausted.
Every time the massive dildo pressed into her uterus, it felt like she might cum
but no matter how strong the pleasure, she could never climax from a toy like this.
Kkeuk... uuk... haaa...
Even jamming the dildo in so hard she thought she’d tear, Heo Seong-ah could only bite her lip in frustration at her unfulfilled, aching orgasm.
The only way she could truly finish was with the reward time every night.
I’m trying my best, Master..!
Desperately hoping for her reward, she rocked her hips to become the perfect cock-sleeve for her master.
Huuuuk..!
Fighting trembling legs, she sat up, clasped her hands behind her head,
looked straight ahead and squatted up and down like an obedient livestock.
Kk, uuk... uuuuuk..!
A female livestock is a convenient onahole for her master.
When having sex, she has to move her body to serve his cock, and when Master uses her directly, she must squeeze and pull with all her might.
To practice, Heo Seong-ah threw her hips up and down atop the mannequin.
Kkhaaaang..! haaaang... aaaaaaa..!
Using the recoil of each thrust, she raised her hips and hammered the dildo to the base.
Losing herself in the rhythm, from exhaustion she barely noticed her aching legs.
Aaaang..! aaaang! aang!
She couldn’t tell if she was human, livestock, or a machine.
Every time she rocked, her juice-soaked butt slapped against the mannequin, making lewd noises that echoed in the basement.
Totally different from the dirty creaks of self-pleasure,
the sound was like slapping a wide board with her ass smack, smack pure shame resounding.
Aaaang..! aaaaaaang!
Her mouth hung open, drooling, moaning filthy cries.
She hadn’t meant to make a sound,
but every time the dildo smashed into her uterus, she cried out involuntarily.
Aaaaaaang..!
Picturing actual sex with her master, Heo Seong-ah smiled with dazed eyes,
legs spread, hands behind her head in a vulgar pose.
Her breasts bounced wildly as she squatted, making her look even more wanton.
“Damn, that’s hot, isn’t it?”
Watching the video without a word, Jun-ha fondled her breast and smirked.
Heo Seong-ah… never dreamed she’d look like such a pervert, blushed in shame.
Glancing at Jun-ha, she saw his bulge straining against his pants.
“Master, let me serve you..!”
Determined to fulfill her role as livestock, she dropped from the couch and knelt at Jun-ha’s feet.
As she reached to undo his pants, Jun-ha stopped her, eyes still focused on the TV.
“Wait. I want to finish the video and check your training, first.”
“A-no, Master... let me serve you, please, stop watching...”
“Hm?”
Jun-ha couldn’t quite understand why she was so insistent.
“Do you want sex that badly? Don’t beg so much after the video, I’ll fuck you.”
“Ah... uu... yes, Master...”
Judging that it was just because she wanted sex, Jun-ha smiled and patted her head lovingly.
With her showing off the perfect female livestock behavior, he planned to reward her as much as she wanted.
“Sit back beside me. Let’s finish the video together, okay?”
“Yes, Master..!”
Awkwardly, Heo Seong-ah cautiously sat at his side,
Jun-ha turning his attention back to the remaining footage.
Aaaang... haaang..!
On video, Heo Seong-ah trembled, never pausing in her squatting.
If she stopped even once, the rhythm would break and it would be hard to keep going.
Stopping was not allowed until 100 reps were finished.
Kkeuk... uuk... haaaang..!
Pang, pang, pang
Her ass slapped lewdly, and soon her movements grew weak with fatigue.
Kkeueueuha...
She was really at her limit.
Her stamina was absolutely spent.
How long had she been at it? Surely she’d already passed 100.
Shivering and panting, she checked the counter at the dildo’s base.
Huh?
The moment she saw the number, she froze in shock.
Because on the counter,
where there should have been a number over 100,
the display still read 000.
