Pain far exceeded pleasure.
"Aaah... Aaah...!!"
Heo Seong-ah tried to escape the stimulation by bending her waist and leaning forward, but the manager held her pelvis in place.
"We're still far from done. If you react like this from the start, what will you do later? Please endure it quietly."
"Khkhkhkhk... Khkhkhkhk..."
It wasn't easy to remain still as instructed.
"Aaah... Aaah...!!"
If her anus were normal, she might have been able to grit her teeth and bear it. However, with her anal sensitivity now rivaling that of a vagina, Heo Seong-ah couldn't help but thrash about from the intense pleasure.
Moreover, the inside of her intestines felt pain that was far from pleasure, akin to being cut with a sharp blade and pierced with a red-hot needle.
"Ah... Aaah...!!"
The pleasure from her anus and the pain deep within her body stimulated her brain in discordant rhythms. Heo Seong-ah screamed with a cracked voice, feeling like she was going mad.
"Aaah... Aaah...!!"
As the dildo was inserted further, the force pushing it out grew stronger. With about 1 cm left, the manager pressed the base of the dildo with both hands.
"Khkhkhkhk...!!"
No matter how hard he pressed, it wouldn't go in further, and the pushing force caused the dildo to protrude slightly.
"Hmm..."
It was surprising that it had gone in this far. Still, since they had started, they should see it through.
"B62, are you ready?"
"Khkhkhkhk... Haa... Ua..."
"B62!!"
"Yes... Yes..."
The manager tried to rouse Heo Seong-ah, who was reacting like a beast, lost in pleasure.
"I apologize... Khkhkhkhk..."
Sometimes, he needed to shock her back to reality. It seemed she needed more physical strength, but completely breaking her might not be bad either.
"B62, just a bit more and it will be over. Do you understand?"
"Yes..."
"Since it won't go in any further, we'll proceed with our method. Please endure the pain and don't faint."
"Yes...?"
As soon as the manager finished speaking, he pressed down on Heo Seong-ah's waist with his left hand, forcing her abdomen against the ground.
"Aaah..."
She was forced into a humiliating position with her buttocks raised. While keeping her waist pinned, he reached down with his right hand and grasped the base of the partially protruding dildo.
However—
Thud—
The manager clenched his fist and tapped the dildo gently, as if hammering, to secure its position.
"Khkhkhkhk... Khkhkhkhk..."
Even this light stimulation caused pleasant vibrations, making Heo Seong-ah tremble and moan.
"Haaah..."
Now, her lewd moans flowed out habitually. The manager was excited, anticipating the moment when her voice would turn from pleasure to screams of pain.
"B62."
"Yes... Hic!"
Thud—
The manager deliberately spoke to her and, as she responded, struck his fist again. The dildo slid fully into her anus, causing an excruciating sensation as her internal organs were compressed.
Heo Seong-ah lost consciousness with a scream.
"Has she fainted?"
The manager was disappointed that she couldn't endure even this level of pain.
Beasts have no time for rest, especially not after fainting from extreme pain. Heo Seong-ah should immediately regain consciousness and fawn over her owner.
Of course, such mental training wasn't the responsibility of the shared facility. Her future owner would modify her as they pleased. If desired, they could use drugs for mind control, though this was not recommended due to high risks of side effects.
"Haa... The future looks bleak."
The manager, contemplating B62's future, shook his head and pulled out a three-section staff from his coat pocket. He considered striking Heo Seong-ah's buttocks but changed his mind upon seeing her trembling and sobbing.
Pain should be balanced with pleasure. Since she had suffered enough with the anal plug and fainted from the pain, it was time to awaken her with sweet pleasure.
The manager put on latex gloves and reached between Heo Seong-ah's legs, tearing open the hole in her suit to expose her vagina. The warm, moist area emitted pheromones that could entice males.
Despite her fainting, her body still responded with arousal, as if she were dreaming of having sex. If so, the shock of returning to reality could be devastating.
"B62, you must wake up now. Something serious might happen if you don't."
There was no response from Heo Seong-ah, who was unconscious.
"I warned you. Don't regret it."
The manager pulled out his phone and contacted someone. He was about to receive a newly manufactured drug from a colleague in the processing department.
After the call, a young man in a white lab coat entered the room.
"Ah, senior... I'm really busy. Don't ask me to run errands like this~"
He scratched the back of his head, showing a lively demeanor different from other staff.
"Sorry, it's just the situation..."
There was an unbreakable rule that beasts and handlers must always be together, especially in open spaces, to prevent any potential bloodshed. This rule was born from past experiences of beast rebellions.
"Okay, fine. Next time, you have to help me out, deal?"
"Ha ha, got it."
The two exchanged typical senior-junior banter, sharing awkward smiles. The researcher secretly handed the manager a small vial of pink liquid.
"This is extremely dangerous. If it's discovered, there will be big trouble."
"I thought the experiments were already done, and we had permission to use it on beasts?"
"No... That's not the point. I brought it without permission."
The researcher glanced around nervously and whispered, "So, if it's discovered, please don't reveal my name. Just say the senior took it secretly."
"Alright."
Though he said this, if caught, he would confess to his actions. The facility was fully surveilled, making it easy to trace the origin of the drug.
"Be careful using it. You know it's effective on men too, right?"
"Really?"
"Yes... If something goes wrong, I know nothing."
The researcher, deflecting responsibility, quickly left the room.
If not for his warning, the manager might have handled the dangerous drug with just a latex glove.
"Ow..."
The manager shivered and retrieved thick, waterproof gloves from a box under the shelf. These gloves, often used for welding, prevented the drug from penetrating.
The box contained various protective tools and safety equipment, indicating that such precautions were necessary for handling dangerous substances. The protection was only for the handlers, not the beasts, who were of no concern whether their bodies or minds were damaged.
If Heo Seong-ah had seen the contents of the box, she might have realized the implications and become even more fearful.
