Breast Modification (3)
Heo Seong-ah sensed the manager's presence right in front of her.
"Kgh..."
Just standing there obediently, doing nothing... goosebumps prickled across her entire body. Her frame trembled as she braced herself for the touch of his hand, not knowing when it would come.
"Hic... hngh..."
The manager unbuckled his belt, pulled his pants down to his knees, and squatted down. Pondering the best position, he pressed his knees to the floor and shuffled forward a bit more. The alignment was a little off, but it was enough for Heo Seong-ah's breasts to line up reasonably with his crotch.
"Hoo..."
Gripping his fully erect cock in one hand, the manager spread his other hand wide and boldly slapped her breast.
Slap─
"Kyaaahhh! Hahk! Gah! Heuaak! Kghaaang! Kgh!"
The instant the blow landed, Heo Seong-ah twisted her waist, choking on her breath from the strangling pain around her neck before shaking her hips side to side and bucking her pelvis. She thrashed for a long while before finally steadying her posture and catching her breath.
"Heuk... haa... kgh..."
"Haha, I just wanted to see your tits jiggle, so I gave them a smack."
"Kgh..."
Thanks to the drug's effects, her swollen, voluptuous breasts hung heavily downward. Even after rapid growth from the medications, they retained their beautiful shape—proof that natural health made all the difference.
"Livestock Number B62, they look splendid."
"Kghr..."
This size was perfect—not too big, not too small. They jiggled just right in everyday movement, enveloped any cock completely, and slapped up and down rhythmically during a titfuck, providing exquisite visual stimulation. Like a signal of her own arousal, her stiffly erect nipples were another captivating highlight.
"Hic, kgh..."
The manager lightly tapped her jiggling breasts, feeling their weight. The heft in his hands was impressive—surely she could feel it too. Contrary to his assumption, adrenaline surging through Heo Seong-ah numbed any pain. Still, she sensed a faint unfamiliar heaviness in her shoulders. By evening, the ache would probably keep her tossing and turning all night.
"Livestock Number B62, this is truly the last step—just four more injections, and your training will be complete. Understood?"
"Y-yes... eh..?"
What drug was he injecting now? Shivering in dread, she recoiled, but the needle was already piercing her breast.
"Aaaahhh!"
Her sensitivity maxed out, her breast exploded with insane agony from even the thin needle. One shot in each breast, and one in each nipple. The nipple injections held about 50ml, unlike before.
"Haaahk..!"
She felt the liquid sloshing inside her breasts. Heo Seong-ah let out a groan, acutely aware of their newfound heft.
"Unlike the previous injections, this is a fast-acting drug, so the effects will show right away."
"Kgh... hngh..."
As the manager said, after about five minutes, the injected areas felt strange.
"Ah... eunggh..."
Oddly, there was no pain—just an unpleasant sensation like her breasts were turning gooey.
"Hic... hnggh..."
As time passed, the sensation dulled further. The masses of fat she knew were there felt detached from her body, like they weren't hers anymore.
"Aah..."
Gradually... a terrifying emotion crept in. Blindfolded, she had no idea what was happening. The thought of her breasts being reshaped to the manager's whims filled her with dread.
"Hmm... that should do it."
Heo Seong-ah's breasts had transformed dramatically. Her modest D-cups had become slightly sagging F-cups, and the latest drug had softened their texture too. No longer taut like water balloons, they now felt like squishy slime.
To test the results, the manager reached out and grabbed her breast.
"Kghk..!"
Still mid-modification internally, Heo Seong-ah clenched her teeth against the crushing pain and swallowed a moan.
"Oh..."
Just a light squeeze elicited an involuntary gasp of admiration—the softness was incredible. His fingers sank in completely, breast flesh bulging erotically between them.
"Euk... kgha..."
Every time he kneaded, they jiggled excessively, utterly mesmerizing. At this level of softness, they'd draw every man's gaze just from walking or breathing.
"Excellent work, Livestock Number B62. I've never seen such a perfect pussy house."
"Hngh..."
Praising her as the ultimate female livestock—flaunting a body that oozed lewd pheromones and aroused any male without fail—the manager grinned lecherously. With playful fingers, he toyed with her breasts: tugging, stretching, squishing, pinching... An endless source of fascination, a texture he'd fondle all day. Cupping around the areola and pressing down hard... finally triggered the nipple drug's effect.
"Kgh... hngk..!"
A thin stream of milky fluid trickled from the tip of her pink nipples.
The manager dabbed a bit on his finger and tasted the watery white liquid.
... ...
"Hmm..."
Flavorless. No taste at all. Without pregnancy, even with all the hormones, sweet milk wouldn't flow. Settling for the fact that milk came at all—the whole point—he moved on.
"Breast modification complete. Unlike your ass and urethra, since it was just drugs, it finished quickly."
"Kgh... hngh..."
Had the request been for fuckable nipple holes, it would've taken far longer than any other training. A small mercy—her future owner had gentlemanly tastes.
"Good work."
"Y-yes..."
The manager unlocked the cuffs on her wrists. After all the struggling, her wrists throbbed; ignoring his gaze, she rubbed her arms to ease the pain. After a while... curiosity about her modified breasts got the better of her, and she instinctively cupped them.
"Euk..."
Thankfully, they were still attached. Aside from the size increase and softer feel, nothing seemed wrong.
"Hoo..."
She sighed in relief, steadying herself—then the manager tapped her knee sharply.
"Livestock Number B62, what do you think you're doing?"
"Hngk!"
Realizing her mistake instantly, Heo Seong-ah jolted and placed both hands on her knees.
"S-sorry..."
"Do you know what you did wrong?"
"Y-yes..."
"Then tell me exactly what it was."
"Hngh... As a female livestock... I moved without permission... and touched my breasts..."
"Hmm. If you know that, why did you do it?"
Why? It was her own body—surely touching it was normal? She'd just forgotten her status as female livestock for a moment.
"I'm sorry..."
Sorry a thousand times over wouldn't suffice, yet oddly, the manager let it slide without anger.
"Fine. Touching your tits doesn't matter anyway."
"P-pardon? Y-yes..."
"Just don't look at your pussy. You know that, right? If you masturbate carelessly or poke fingers in and damage your hymen... your entire value as Livestock Number B62 vanishes."
"Hngh... Yes, I'll remember..."
"Good. As long as you know."
Her value now lay in her virginity. The thrill was corrupting an innocent virgin into a filthy slut. If her hymen broke, the manager would face consequences too. And Heo Seong-ah? Far worse treatment—maybe even limb-severed onahole in the worst case.
"Livestock Number B62."
"Yes..."
"Like just now, place both hands on your chest and touch them."
"P-pardon..?"
"What are you doing? I've told you multiple times not to question orders you've heard clearly—do you need to suffer to fix that habit?"
"N-nooo! Sorry!"
"Then shut up and do as you're told, quickly."
Trembling in fear, Heo Seong-ah moved her hands to knead her breasts.
"Good. Keep rubbing like that."
"Hngh..."
Under the manager's capricious command, she massaged diligently, swallowing hard. Pain? Pleasure? Her numbed breasts registered nothing.
"Hic, hoo..."
Why make her do this? She truly couldn't understand.
