EP.119 Breast Modification 

After walking for a while, they arrived at a place called the Breast Training Room. 

Though it was a small room of about 5 pyeong like the others, its structure differed due to its different purpose. 

First, the floor of the Breast Training Room was made of hard marble. 

While the shelves were filled with scary-looking tools like in other rooms, this room uniquely lacked restraints and devices. 

In the center of the room. 

A thick metal rod protruding from the floor was a particularly eye-catching structure. 

A large circular ring was attached horizontally to the top of the metal rod. 

No one could tell its purpose just by looking at it. 

"Huu..." 

Sensing the unusual atmosphere, Heo Seong-ah trembled and swallowed her voice. 

For some reason, chills ran down her spine and her body shuddered. 

It wasn't her first time receiving training, but... 

What was so scary about this? 

"Mmph..." 

Breast modification? Training? 

How exactly would they modify her breasts... 

Unable to predict, the more she thought about it, the more her fear seemed to intensify. 

"B62." 

"Hic!" 

While she was zoning out... 

Heo Seong-ah's shoulders jerked as she felt the manager's hand suddenly pat her head, sending chills through her. 

"Why are you so surprised? Just follow me quietly." 

"Mmph..." 

The manager pulled on her leash and walked to the center of the room. 

Reaching the metal rod, he untied Heo Seong-ah's leash and grasped her shoulders to sit her down. 

She ended up kneeling in a polite posture. 

"Stay still." 

"Mmph!!" 

The band covering her mouth was removed and the dildo filling her throat was quickly pulled out. 

In the past she would have dry heaved with tears, but... 

Now accustomed to such stimulation, Heo Seong-ah could suppress her gag reflex by clenching her mouth shut and holding her breath. 

"Hmm..." 

Seeing the excellent results of the training, the manager thought to himself that he should use an even thicker dildo. 

"B62, sit up straight with your back straight and look forward. Begin." 

"Ugh, yes..." 

Not knowing what would happen, she moved her body as instructed. 

Kneeling, she brought her hands in front of her navel and sat up as straight as possible. 

The metal rod behind her back moved up and down, and the ring opened wide to constrict her neck. 

"Gah!" 

"Stay still. If you want to finish quickly, don't move." 

"Nngh...!" 

The manager slowly turned a dial to adjust the ring size until Heo Seong-ah's neck was slightly loosened. 

Then he adjusted the rod length to fix her in place so she couldn't move while sitting up straight. 

"Huh... Ugh..." 

As a result, Heo Seong-ah was unable to move at all while kneeling. 

If she lost focus and bent her waist even slightly, the metal ring would press on her neck and choke her. 

But the uncomfortable posture made it difficult to twist her waist, and kneeling made it hard to move. 

"Nngh..." 

Though only her neck was fixed to the metal rod... Heo Seong-ah's body had no choice but to quietly receive training, deprived of freedom. 

"Good. Now put both hands behind your back." 

"Yes..." 

As she obediently stretched her hands behind her back, the manager connected her wrists with chained handcuffs. 

The very short chain passed through the metal rod and was fixed, making it impossible to extend her hands forward. 

"Now you're ready for training. I'll gather the necessary tools, so stay still." 

"Ugh... Yes..." 

The manager walked to the shelves and selected tools needed for Heo Seong-ah's training. 

"Hmm... Which should I use..." 

There were countless ways to develop breasts. 

Using drugs to enlarge them to the point of making daily life impossible, or making the nipples as sensitive as the clitoris so they'd squirt at the slightest touch, or turning the breasts themselves into new erogenous zones to create a vulgar body that couldn't even wear a bra. 

Further, stimulating the mammary glands to promote milk production, or modifying the breasts' function to create grotesque holes for inserting penises. 

Or externally adding piercings to tie the breasts together, or shaping the nipples as desired to make them into toys... 

"Hmm..." 

It's a difficult decision. 

Really. 

Unlike other body parts, breasts have no physical limitations, so they could be modified in any way the owner desires. 

There are endless possibilities, but... 

"There are no specific requirements." 

Maintain virginity. I'll be the first to take it. 

Make her scream in pleasure no matter where she's touched. To the point daily life is impossible. 

Make her fear me. So she can never resist. 

Keep her mind intact and sane. So she can reflect on her mistakes for life. 

Fully develop all areas except the vagina. Also to the point daily life is impossible. 

Among the requirements from Heo Seong-ah's future owner, there were none specifically about "breast modification". 

Strictly speaking, items 2 and 5 could be considered requirements, but the scope of modification is so broad that it's unclear exactly what to do. 

He didn't want to contact the owner individually to ask either. 

"Hmm..." 

Well... For now, how about modifying the entire breasts to be as sensitive as the clitoris... making them so sensitive that normal life becomes impossible? 

And add a slight modification... to make them spray milk with every orgasm? 

Improve the texture to modify them like soft, squishy slime? 

It would be good to keep the nipples permanently erect so their sensitivity doesn't decrease... 

Heo Seong-ah's breasts are a bit small now, so enlarging them enough to fully envelop a penis would be good too. 

"Haha..." 

Just imagining it made him so excited he laughed involuntarily. 

A part of the body she thought was "hers" for life will be modified into a tool for men's sexual gratification starting today. 

"Whew... Let's do it. We must." 

Increased sensitivity, erect nipples, texture modification, milk production, size alteration... 

Those modifications could be done at the manager's discretion without needing permission, so he gathered all the necessary tools and put them in a box. 

Thud thud— 

He deliberately made footstep sounds to increase Heo Seong-ah's fear. 

The rattling of the box shaking with his footsteps also added to her fear. 

"B62." 

"Hic!" 

Startled by the manager's cold voice suddenly, Heo Seong-ah's shoulders jerked. 

As her posture slipped, her neck was choked and she gasped for air before barely escaping the pain. 

"We'll now begin the training." 

"Yes..." 

"If today's training ends successfully, B62 will feel grateful to me." 

"Yes...?" 

Though she couldn't understand the manager's intention in saying that... she had a vague idea. 

The modifications they were about to do were essentially transforming her "breasts" themselves. 

While the internal changes were unknown, externally her breasts would be reborn into a perfect form. 

"You'll surely like it." 

"Ugh..." 

Breasts that anyone, male or female, would find beautiful. 

Walking down the street, exercising, eating at restaurants, watching movies... in all aspects of daily life, Heo Seong-ah would now receive "the gaze of others". 

For someone who likes attention like her, there could be nothing better. 

Of course, this is assuming she wasn't female livestock. 

Right now, Heo Seong-ah's breasts were at best just attractive accessories attached to a penis sleeve. 

Thinking of the owner who would monopolize Heo Seong-ah... it truly made him angry with jealousy. 

"B62." 

"Yes... Manager..." 

"Today there is no freedom until the breast modifications are completely finished. Understand?" 

"Ugh, yes..." 

There was no freedom to begin with... 

He was calling that brief moment right after training "freedom". 

Using the few minutes of comfortable rest time per day as collateral, the manager reached his hand toward Heo Seong-ah's body. 

Moving his hand up and down from her solar plexus, he opened the black latex suit wide to expose her breasts. 

Her breasts, coated in aphrodisiac and bare without a bra, jiggled as they were revealed. 

"Haa..." 

Constantly wrapped in the suit without air contact, they still had a glossy sheen despite a full day passing since the aphrodisiac was applied. 

The manager reached out and rubbed his palm over her entire chest, as if spreading the slippery aphrodisiac. 

"Haa... Hah... Ha..." 

Her spine shuddered each time her erect nipples were bent between his fingers. 

Heo Seong-ah tightly clenched her legs as a bittersweet pleasure surged through her. 

"Ugh... Nngh..." 

"You can climax if you want." 

"Nngh...!" 

She wanted to climax with all her heart. 

But... 

No matter how much she tensed her thighs to squeeze her groin, or conversely relaxed and focused all her nerves on the stimulation to her breasts... she simply could not reach climax.
