Black Twilight's Imprisoned Slave Life (Machine Ravishment, Lewd Hypnosis Service) (1)
Whirrr... whirrr... whirrr... whirrr... whiiiirrr.
Aah... ugh... hnnngh...!!
In the modification and torture chamber of the underground illegal facility, Underdog Club.
Today, too, the imprisoned magical girl Black Twilight is being toyed with by the machines here.
Strapped tightly to a surgical chair with her arms and legs restrained, electrodes and injection needles for drugs are stuck all over her body. Milking machines are clamped onto the tips of both her breasts, mercilessly extracting her milk.
Piston machines with dildos attached thrust back and forth into both her pussy and ass.
The vicious protrusions on the dildos pounding both holes rub roughly against every nook and cranny of her pussy, making it unbearable. But above all, the periodic spurts of aphrodisiac slime from the dildo tips—like it's ejaculating—drive Black even further into madness.
Amid various mechanical whirs, other devices tease her body in all sorts of ways before moving on, only for new ones to attach and modify her... and repeat.
Normally, they'd space out the modifications to account for the subject's burden, but Black was different—no need.
A magical girl's sturdy body adapts flawlessly even to the harshest mods, recovering stamina and mental fortitude overnight. No need to hold back much.
Thanks to that, Black's modification intensity and pace were unprecedented.
At this rate, in about a month, she'd be so changed she couldn't live a normal life anymore.
No, she might already be beyond returning to normal...
"Oh, what's this? You up to something, Navi-kun?"
No, I am not doing anything.
Into the room filled only with mechanical whirs and Black's moans, someone entered.
The Underdog Club member eyed the navigator robot hovering like it was watching over the modified Black. It briefly turned its camera toward him, then back to her.
"Then what? Why're you here?"
.........
The robot Black called Navi-kun fell silent, as if no answer was needed.
The Underdog member eyed the robot suspiciously.
Black's hypnosis program overhaul was already done. No need for the navigator bot here anymore.
Navi-kun gave no reply. No real reason to press the robot, so the man shrugged it off. Honestly, he didn't care what the thing did or where it went.
The man approached the writhing, restrained Black and shoved aside the piston machines thrusting into her holes.
Her freed holes twitched. From her soaked pussy, the thick aphrodisiac slime mixed with her juices gushed out with a glorp...
He scooped up the slime with his hand, fingered out more from inside her, and slathered it thickly on his cock. This aphrodisiac slime induced powerful arousal in females but acted as a stamina and rigidity booster for males.
With his slime-coated cock, he plunged deep into Black's pussy.
Her hypersensitive pussy made Black exhale a long, pathetic moan through the ball gag in her mouth.
As the man thrust his hips, her lewd body rocked in sync.
"Heh heh, that's the stuff. Couldn't focus on work all day 'cause I kept thinking of Magical Girl's pussy taste. Had to wait for the mods to finish."
Her pussy, pounded relentlessly by thick dildos, still clenched his cock oh-so-pleasurably.
Yet from the aphrodisiac's effects, just a few thrusts sent her hips bucking in orgasm.
In response to her climax, the milking machines suddenly ramped up milk production. It seemed structured to increase output with the magical girl's arousal.
Black felt immense pleasure from lactating too, losing her mind to the chain of orgasms.
"Looks like the tit and milk mods turned out great..."
He kneaded her machine-clad breasts with his big hands.
Milk sprayed even more vigorously. Black shuddered happily.
Black's milk had a great reputation. He'd offered samples to some customers before, and they all raved.
For merchandise value, she'd need to produce even more.
Slapping flesh echoed for a good while.
Black's crotch smacking against the man's hips.
After enjoying himself thoroughly, the man fed her a thick creampie.
Black, who'd cum countless times already, climaxed again from the sensation of semen flooding her—violently enough to squirt as high as the man's height.
Not satisfied with one load in her pussy, he readjusted her restraints and switched to her ass.
Uuung... mmph...!
Her ass, modified even more sensitive than her pussy, made her pale body twitch with every thrust.
The powerless magical girl, fucked like a toy or onahole, was silently watched by the hovering Navi-kun.
Black Twilight's imprisonment in this illegal club drags on.
No windows in the basement, no clocks—she couldn't even tell how many days it'd been.
Counting meals roughly, at least ten days.
Still no aid from the Hypnosis Factory. Maybe they hadn't even noticed she was gone.
Makes sense—such a big operation wouldn't last if it was that easy to bust.
Black had racked her brains for escape, but no breakthroughs.
Her freedom so restricted, she'd observed intently for escape hints, gathering info. But the more she watched, the more her own powerlessness sank in.
They'd been at this for years; the operation was vast and deep.
Underdog members were pros—seeming lax at a glance, but airtight on closer look. No gaps.
Not something an untrained, magic-sealed rookie magical girl could exploit.
But she couldn't just stay like this.
What made Black anxious was her hypnosis program's control strengthening daily.
Sometimes memories blanked; her body moved against her will.
She'd resisted at first, but felt that will weakening over time.
What if a bit more time passed? Would she become a docile doll, accepting life as their pet, slave, or merch without a thought of escape?
She had to act before then.
But despite her resolve, the situation remained hopeless...
Ugh... mm... hnnngh...
During a mealtime.
Dragged from her cell, Black puts on a masturbation show in a windowless room, surrounded by men.
The men casually eat fancy dishes and booze, chuckling at her shameful, erotic display.
This was Underdog's meeting room; the men, its members.
They often summoned her like this for their amusement.
Unable to resist orders, Black masturbated furiously with her hypersensitive modded body, cumming hard before them.
Milk leaked from her nipples untouched—a savory delicacy infused with magical girl mana...
"Huuht... hnnnght... Cumming... cumming again... watch me, watch the magical girl cum from fingering... just came but this pathetic pussy's cumming again... watch it all, watch every bit... no, don't watch... it's embarrassing... aaah, please watch... watch me..."
Against her will, her mouth flirted and confessed climaxes.
Black shook her head no-no-no like she hated it, but shameful, seductive words kept spilling.
Her fingering hand didn't stop.
As declared, she reached a vulgar orgasm, fingering her pussy. Her body shuddered; breasts jiggled.
Drool dribbled sloppily from her pursed lips; milk jetted from her nipples in response.
Fingering orgasms felt too good already; added lactation pleasure was unbearable.
Shuddering in afterglow, her hand soon resumed before it faded.
Black's eyes widened.
"A-ah...! Wait... just came... stop... please stop...!"
Thus, throughout their meal, Black performed nonstop masturbation, cumming endlessly.
Afterward, she serviced them orally or with her pussy in eating order, milking a load each.
Only after everyone finished could Black finally eat...
