Heo Seong-ah's arm restraints were removed, but her legs remained bound. Thanks to the long chains, she could crouch without much difficulty.
"Umm... Umm..."
"B62, do you remember the waiting posture?"
"Umm..."
The manager spoke with concern, wondering if Heo Seong-ah's brain had been damaged by pleasure. If she didn't remember, he planned to torture her until she recalled it. Fortunately, Heo Seong-ah remembered and moved into position on her own.
"Umm... Umm..."
She spread her legs horizontally and placed her hands behind her head. The manager found her appearance, wearing a black latex suit with her legs wide apart, comically amusing.
"Good. Normally, animals must assume a defecation posture when excreting, but I'll make an exception this time."
The manager placed a rectangular tray under Heo Seong-ah's buttocks.
"Before you defecate..."
"Umm... Umm..."
He gently stroked her nape and released the buckle of the leather band around her neck.
"Khkhkhkhk..."
The dildo mask in her mouth loosened slightly. As she exhaled and bowed her head, the manager suddenly pulled the base of the dildo.
"Uuuuuuueeek!!"
The dildo, which had invaded her stomach, was quickly pulled out. The semen that had filled her stomach flowed back up through her open throat.
"Huuu... Haaah..."
Heo Seong-ah let out agonized moans as she vomited a thick, white liquid. The sight of a pretty girl vomiting semen with a pained expression stirred a base desire deep within the manager.
Unbeknownst to him, he became aroused. He wanted to rip off the suit and penetrate her, but he wasn't reckless enough to risk his life over a single mistake.
"Umm... Umm..."
The manager restrained his desire, thinking about Heo Seong-ah's future as a completed product.
"B62."
"Haa... Umm... Yes..."
"Do you know about Sli-Fs?"
"Eh?"
[Sli-Fs]
The term was unfamiliar, but it seemed like something she had heard before.
"As a student at a prestigious university, I thought you would know."
"Aaah... I don't know... Huh?"
Heo Seong-ah's memories from before she became a beast were fading. She was unconsciously trying to forget her past.
The more she thought about it, the more despairing her current life became.
"Khkhkhkhk..."
Sli-Fs... She might remember if she tried, but Heo Seong-ah shook her head and stopped thinking.
Recalling her past, especially her college days, filled her with sadness.
"Khkhkhkhk..."
Tears welled up as she remembered. She couldn't even cry freely in her miserable life as a beast. Heo Seong-ah composed herself, pretending to be okay.
"I see. Well, it's understandable. Not many students study it deeply since it's not a required course."
There was a high school course called "Shared Objects/Beasts" in the arts and physical education department. Since it didn't affect internal assessments, many students glanced over it without interest. Male students in puberty might read it out of curiosity, but female students often didn't even open the textbook because they empathized with the beasts.
Heo Seong-ah, who had always been a model student with excellent grades, was no exception. She had condemned the dehumanizing treatment of women as beasts.
"Let me explain Sli-Fs briefly. It doesn't matter if you don't know, but it's good to understand."
The manager began his explanation with a smile, aiming to deepen Heo Seong-ah's despair and regret for her life.
"Sli-Fs is a new drug developed to efficiently manage the excretion of beasts."
He showed her a small, spherical pill. The transparent capsule contained various colored particles.
"Do you understand what it means to efficiently manage excretion?"
"I don't know..."
"It's natural you wouldn't. From now on, I'll teach you how a female beast like you excretes."
From now on, Heo Seong-ah would no longer urinate or defecate normally. As a complete beast, she would excrete in a special way.
"The purpose of a female beast is to satisfy men's sexual desires. Your entire body exists to make men happy, and you must produce semen with a happy face, no matter what part of your body is used."
"Yes, sir..."
This harsh reality was unavoidable. Heo Seong-ah couldn't even think of resisting anymore.
"To achieve this, your mouth, urethra, vagina, and anus must all be modified. B62 is currently undergoing this process."
"Yes..."
The oral training was complete. After the anal modification, her urethra would be next. Heo Seong-ah shivered at the thought of the three-day hell ahead.
"Let's get to the point. Initially, many complaints were filed by owners who used female beasts. They mainly struggled with managing the beasts' excrement."
It was understandable. While some people fantasized about anal sex, few enjoyed watching or cleaning up after a woman defecating. Many people felt a strong aversion to dirty acts, not just excrement management but also cleaning the body.
"That's why Sli-Fs was developed."
The manager held out the pill. Heo Seong-ah couldn't see it due to her blindfold.
"Taking one of these pills will permanently change your body."
"Umm...?"
Without further explanation, the manager opened Heo Seong-ah's mouth and dropped the pill onto her tongue.
"Khkhkhkhk..."
He inserted his finger to push the pill deep into her throat. Heo Seong-ah swallowed it involuntarily and felt a strange sensation in her abdomen.
"That's it. Your excrement will now be easier to manage."
"Umm...?"
Just one pill could change her body? It was hard to believe, and she couldn't grasp what this easier form of excretion meant.
"Sli-Fs absorbs nutrients from human waste and supplies them to the body."
"Umm... Umm..."
"It might be hard to understand. Simply put, your urine will become a colorless, odorless liquid that's so clean you could drink it. And..."
The manager stroked Heo Seong-ah's anus through the latex suit. She was startled by the sudden stimulation and arched her back.
"Huuu... Umm..."
Now, even gentle touching of her anal folds brought intense pleasure.
"Your feces will become solid, rod-shaped objects that are odorless and colorless, similar to your urine. They can be disposed of like regular trash and are harmless if ingested, though few people would have the hobby of eating excrement."
"Aaah... Aaah..."
The explanation meant little to Heo Seong-ah as the manager continued to touch her anus.
"One more thing: Sli-Fs is a sentient object."
"Umm... Eh?"
This wasn't entirely accurate; Sli-Fs consisted of artificially cultivated parasitic eggs. Once ingested, these eggs took over the functions of the stomach, intestines, and bladder, absorbing waste and converting it into energy, minimizing the residue to be expelled.
In other words...
"From now on, B62 will no longer have control over excretion."
"What does that mean?"
If the parasites in her body wanted to excrete, her anus and urethra would open involuntarily, leading to humiliating defecation. Trying to resist by tensing her sphincter would be futile.
"Therefore, B62 will live with anal and urethral plugs for the rest of her life. A beast can't just defecate anywhere, can it?"
"Umm... Huh..."
Just one pill had taken away Heo Seong-ah's freedom to excrete as a human.
