#25 Enslaved Magical Girl (Black - Milk Modification/Cowgirl Service) (1)
Three days had passed since Black Twilight was imprisoned in the underground club Underdog Club.
One day flew by with Navi-kun's hypnosis program update and modifications, followed by two days of evaluations and training by the Underdog members, passed around among them one by one.
In that time, she learned a little about the facility's layout and her current situation.
As she'd been told beforehand, this was a place where all sorts of illegal goods were traded.
Starting with women, they dealt in machine parts and drugs available only here, and even modification services on top of that.
"Modification business" meant exactly what had happened to Black.
Using the modification devices here, her entire body had been wildly altered.
Such modifications were strictly forbidden on a large scale, for ethical reasons and more—but that was how it was.
Naturally, the devices and drugs for modifications weren't distributed through normal channels.
But they smuggled in components through some means, assembled them, and for a price, provided modification services to female slaves tailored to their owners' tastes.
They could even do special enhancements to soldiers' bodies, it seemed.
And those dealings took place in the club at the heart of this underground facility.
Black hadn't been granted entry to the club yet, so all she could hear was the noisy music leaking from beyond the door.
She could roughly imagine what went on inside, but...
Such blatant illegal activities were happening right in the middle of the city, yet there was no sign that the Hypnosis Factory side had caught on.
The reason Black had come here in the first place was just that Navi-kun had lured her with bait.
She had a chip implanted in her, and the hypnosis program was structured to report to the Factory if anyone tampered with it.
But three days had passed with no rescue... which meant they'd surely done something on their end.
Please don't do anything foolish and just stay put. You don't need to worry about the Factory tracking you. This business has special devices that constantly jam signals so they can't get out.
"...I have no idea how I'm supposed to feel reassured hearing that."
From inside her prison cell, Black glared at Navi-kun outside the bars like he was her mortal enemy.
Navi-kun was monitoring her, apparently to prepare for any rampage.
Not that she could do anything anyway.
Over the three days of Navi-kun's modifications, Black had completely lost the power to resist.
Her mind's hypnosis program had taken deep root, compelling her to accept their domination.
The updated hypnosis program in Black's head, courtesy of Navi-kun, could now be freely manipulated by them.
She obeyed Underdog members' orders unconditionally, couldn't commit any violence against them, and was restricted from any escape attempts.
At least her rationality remained, letting her view them as enemies—but even those feelings and thoughts could be changed to whatever they wanted, like affection or fear.
This was Black's current situation.
She had no idea if there was any way to overcome it...
Still not sent out to the club, Black was treated today as the Underdog members' exclusive sex-processing slave once more.
"P-Please... be gentle...!"
In the prison cell where Black was confined.
A man from Underdog was embracing her from beyond the bars, fondling and toying with her nipples and breasts.
The man who brought her morning meal had watched her finish eating with a sleazy grin, then immediately pulled her close and started groping her like this.
He wasn't even reaching for her pussy—just obsessively kneading her breasts.
Black's chest, altered into a milking physique by recent drug injections, would occasionally spurt milk—squirt squirt—every time he squeezed.
For the first few minutes, Black endured it in silence, but after fifteen minutes of nonstop breast play, she couldn't help but make noise.
How long was he going to keep groping her?
Couldn't he ease up a bit?
But the man showed no particular reaction to her pleas.
He just muttered something like, "Not yet...?"
What the hell was "not yet" supposed to mean?
And his breast caresses continued.
Twenty minutes... thirty... forty...
Black's mind went blank, turning pure white.
It wasn't just one moment—the subtle pleasure built gradually with every knead of his hands.
Then, at some point—pop.
The amount of milk gushing from Black's nipple tips suddenly surged.
At the same time, indescribable ecstasy flooded from deep inside her breasts and the tips themselves.
"...?! Hiiik?! Wh-What the—?!"
"Looks like the drug's finally kicking in properly."
Black's meal had been laced with drugs.
Tailored to her body modifications so far, they helped her adapt to the changes and activated the implanted functions.
Her breasts had already been turned into milk producers before, but now they generated and spurted several times more milk. A magical girl's milk was produced from mana, so as long as her mana held out, she could be milked endlessly.
On top of that, the pleasure from milking had been greatly amplified.
Just spurting milk brought orgasm-like waves crashing over her continuously.
From now on, every time her breasts were toyed with or milked, Black would be overwhelmed by brain-melting ecstasy, like her mind was being raped.
There were still many more modification results to experience. With each one, she'd despair more at the changes to her body.
"But damn, way more volume than expected. Magical girls really are mana-rich... tastes great too. Could even sell it as a product."
The man kept kneading her tits for a good while longer, enjoying himself. Sometimes he'd latch onto one nipple at a time and suck the milk straight out.
With her breasts' sensitivity heightened even further by the drug, Black wailed throat-scrapingly, trembling violently in his arms.
Every squeeze sent endless milk gushing out, melting her brain further with pleasure...
Black was toyed with in her cell, her tits groped relentlessly, then led by the monster soldier's hand out to his room.
And in the room, not just her breasts—her entire lewd, slutty body was used.
Aah... Nng... Hnngh...
Straddling the sprawled-out man, Black moved her hips on her own, servicing him.
The man just lay there comfortably, while Black diligently worked to please the male, following her implanted commands.
She'd been unable to defy orders from day one, but compared to then, she was far more obedient now.
The mouth that had spat complaints and anger was now meekly shut, leaking only pleasant female moans now and then.
In just a few days, she'd become so much tamer. The man grinned in delight, slapping the massive ass bobbing up and down before his eyes.
Hnngh...
Whether the ass slap felt good or not, Black paused briefly before resuming her hip grinding.
Facing away from the man, ass toward him, she repeatedly engulfed and released his cock with her pussy—schlop schlop schlop...
"Oh, here it comes, Magical Girl. Gonna cum soon."
"Haa... Haa... Nngh... Y-Yes...!"
Lost in pleasure, Black kept clenching her pussy diligently without thinking.
With his cock buried to the root, she rocked her hips back and forth or in circles, stimulating it all over.
Pleased by her service, the man's cock soon erupted, semen surging out in thick spurts.
The vigorous Mech拉克 monster's load filled her insides. As her pussy overflowed with cum, some mixed with her juices and dripped down his shaft to his balls.
"Oooohhhnnn~~~!"
As programmed long ago, the moment she sensed his ejaculation, Black climaxed spectacularly. Chin raised, shoulders twitching, she basked in the afterglow for a long while.
Even after her peak subsided, Black stared blankly into space, lost in the lingering pleasure—but soon her mental program dictated the next action.
Following the command to continue servicing, she dismounted, licking his dirty cock clean with her mouth.
Not just cleaning the still-hard shaft with her tongue, she sandwiched it between her heavy breasts for a paizuri too.
Her nipple tips were stained white from the massive milk leaks.
During sex earlier and at climax, milk had flowed out uncontrollably.
Her body now reacted to pleasure and orgasms by lactating.
The man pinched and twisted both her altered nipples hard.
A tingling ecstasy shot straight to her scalp, and Black let out a blissful sigh, hips twitching again...
