Heo Seong-ah sensed the manager's presence standing right in front of her.
"Ugh..."
Standing still without doing anything... goosebumps spread over her entire body.
She trembled, bracing herself for the manager's touch that could come at any moment.
"Hic... Huh..."
The manager unbuckled his belt, lowered his pants to his knees, and squatted down.
Considering what position to take, he knelt on the floor and moved a bit closer.
Though the position was slightly awkward, his lower body was somewhat aligned with Heo Seong-ah's breasts.
"Huu..."
The manager, grasping his highly aroused penis in one hand... boldly struck Heo Seong-ah's breasts with his other open palm.
Slap-
"Kyaaah! Huh! Gah! Huugh! Aaahn! Ugh!"
As she was hit, Heo Seong-ah twisted her waist, choked and gasped for air from the pain in her neck, then shook her hips side to side and jerked her pelvis.
After thrashing about for a while, she barely managed to steady her posture and catch her breath.
"Huh... Haa... Ugh..."
"Haha, I wanted to see your breasts jiggle so I hit them once."
"Ugh..."
Her breasts, swollen full from the drug's effects, sagged downwards.
Despite being rapidly enlarged with drugs, they still maintained a beautiful shape, as if being healthy was beneficial.
"B62, it looks very good."
"Nngh..."
The current state, neither too much nor too little, was just right.
Normally they jiggle moderately, can fully envelop any penis, and provide excellent visual stimulation as they bounce up and down with each thrust.
Her erect nipples were also an attractive point, as if signaling her own arousal.
"Hic, ugh..."
The manager lightly tapped Heo Seong-ah's jiggling breasts, feeling their weight.
If they felt this heavy in his hands, she must be feeling the weight of her breasts too, right?
Contrary to his expectations, Heo Seong-ah, flooded with adrenaline, felt no pain at all.
Still, she did feel the strange sensation of her shoulders becoming slightly heavier.
Surely by evening she'll be tossing and turning all night from the pain in her breasts.
"B62, now just four more injections and the training will be over. Understand?"
"Yes... Eh?"
What kind of drug was he going to inject now?
She showed a reflex of rejection, her skin crawling, but the needle had already pierced her breast.
"Aaaagh!"
Her breasts, sensitized to the limit, spread maddening pain even from the thin needle's stimulation.
One shot in each breast, and one in each nipple.
The drug injected into the nipples was about 50ml this time, different from before.
"Huuugh!"
She could feel the sensation of liquid sloshing inside her breasts.
Heo Seong-ah moaned, feeling the increased weight of her breasts.
"Unlike what was injected before, this is a fast-acting drug so the effects will appear quickly."
"Ugh... Huh..."
As the manager said, about 5 minutes after the drug was injected, the feeling in her breasts where the drug was injected became strange.
"Ah... Ugh..."
Strangely, there was no pain.
Just an unpleasant feeling as if her breasts had turned to mush.
"Hic... Huh..."
As time passed, the sensation in her breasts became duller.
She had the illusion that the clearly existing lumps of fat had detached from her body.
"Aah..."
Gradually...
A frightening feeling arose.
Unable to see, she had no idea what had happened.
She was terrified by the fact that her breasts were being modified according to the manager's whims.
"Hmm... This should be sufficient."
Heo Seong-ah's breasts had taken on a markedly different shape than before.
Her modest D-cup breasts had changed to slightly sagging F-cups, and the texture had softened due to the drug's effects just now.
Her breasts, which had been like firm water balloons, were now like soft slime.
The manager reached out to grasp Heo Seong-ah's breasts, wanting to feel the effects of the modification himself.
"Nngh!"
As the internal modifications were still ongoing, Heo Seong-ah gritted her teeth and swallowed her moans at the pain of her breasts being squeezed.
"Oh..."
Just lightly grasping her breasts elicited an involuntary exclamation at how soft they felt.
His fingers sank in completely, with breast flesh bulging out between them, which was quite erotic.
"Ugh... Nngh..."
The way they jiggled excessively each time he stimulated them by curling his fingers was very captivating.
If they were this soft... they would surely catch men's eyes just from normal walking or breathing.
"Excellent, B62. I've never seen such a superb cock sleeve."
"Huh..."
He praised her, saying there was no more perfect female livestock than Heo Seong-ah, flaunting a body that exuded lewd pheromones and excited males without lacking anything.
With a lewd smile, the manager kneaded Heo Seong-ah's breasts with playful hand movements.
Pulling, stretching, squeezing, pinching as he pleased... the fantastic texture never got boring no matter how much he played with them.
Saying he could touch breasts like these all day, as he gathered his hands around her areolas and firmly squeezed... finally the effects of the drug injected into her nipples appeared.
"Ugh... Hic!"
A very thin stream of liquid flowed from the tips of Heo Seong-ah's pink nipples.
The manager dabbed the thin whitish liquid on his fingertip and tasted it.
...
...
...
"Hmm..."
It was bland.
A flavorless liquid with no taste at all.
Perhaps because she wasn't pregnant, no matter how much female hormones were released, sweet breast milk didn't come out.
The manager was satisfied just with the fact that liquid came from her nipples.
That was the goal from the start.
"Now the breast modification is complete. Unlike the anus and urethra, it ended very quickly since we only did drug modification."
"Ugh... Huh..."
If there had been a request to create holes in the nipples for inserting penises, it might have taken much longer than any other training.
Fortunately or unfortunately, Heo Seong-ah's future owner was a gentleman with somewhat human tastes.
"Good work."
"Yes..."
The manager unlocked the handcuffs restraining Heo Seong-ah's wrists.
Her wrists were numb from constantly struggling, so she massaged her arms to relieve the pain without minding the manager.
After a while...
Curious about how her modified breasts had turned out, she unconsciously raised her hands and kneaded them.
"Ugh..."
Thankfully, her breasts were still properly attached.
Other than being slightly larger and softer to the touch, there were no abnormalities.
"Huu..."
As she sighed in relief and collected herself, she heard the manager's scolding voice as he tapped his knee.
"B62, what are you doing?"
"Hic!"
Realizing her mistake immediately, Heo Seong-ah startled and put both hands on her knees.
"I-I'm sorry..."
"Do you understand that you did something wrong?"
"Yes..."
"What exactly did you do wrong? Please say it yourself."
"Huh... As mere female livestock... I moved on my own and touched my breasts without the manager's permission..."
"Hmm, if you understand so well, why did you do it?"
Why, she asks.
Touching her own breasts.
Isn't that a perfectly normal action?
She just momentarily forgot she was female livestock.
"I'm sorry..."
Saying sorry hundreds of times wouldn't be enough, but for some reason the manager let it go without getting angry this time.
"Fine. It doesn't matter whether you touch your breasts or not."
"Yes? Yes..."
"But not your vagina. You understand? If you carelessly masturbate or insert your fingers and damage your hymen... B62's value will disappear."
"Huh... Yes, I'll keep that in mind..."
"Good. As long as you understand."
Because Heo Seong-ah's value now lies in her virginity.
There's meaning in turning an innocent virgin who knows nothing into a vulgar female.
If her hymen is damaged, even the manager in charge of her won't be able to avoid responsibility.
Heo Seong-ah herself would receive much harsher treatment than now.
In the worst case, she could become an amputee onahole.
"B62."
"Yes..."
"Please raise both hands and touch your breasts like before."
"Yes...?"
"What are you doing? I've said many times not to keep asking when you've heard properly. Do you need to be hurt to fix that habit?"
"Ah, no! I'm sorry!"
"Then shut your mouth and quickly do as you're told."
Heo Seong-ah moved her trembling hands in fear and kneaded her own breasts.
"Good. Keep rubbing like that."
"Huh..."
At the manager's capricious order, Heo Seong-ah earnestly kneaded her breasts while holding her breath.
Pain?
Pleasure?
She couldn't feel anything with her desensitized breasts.
"Hic, huu..."
Why on earth was he making her do this...
She really couldn't understand.
