BAD ENDING 003: D-Class Lewd Partner Drone Sonia 5

"Sonia is so adorable… but her breasts… no… her breasts are sexy too… I never knew about stuff like this before… why didn't I know…?♡ It feels so good… *smooch*…♡"

Chewing, sucking. Luce clamped the lewd switch between her teeth and gave it a light experimental bite, just to watch Sonia's reaction.

Whether the roleplay program for a genuine lewd drone had been drilled into her that thoroughly, Sonia only kept repeating that she was still in programming mode.

Little by little, Luce was transforming—from an innocent adventurer with inverted nipples who had known nothing, into a filthy pleasure-seeking inverted-nipple adventurer with lewd cow-tits. Her hands kneaded Sonia's breasts like soft pudding, making them sway and jiggle.

Sopping wet… she soaked the thighs she had straddled, then shifted to the other side. The teal-haired short-haired cow-tit adventurer latched onto the nipple she had not yet tasted, leaving behind the one she had already bitten hard enough to stiffen completely.

Sucking on Sonia's lewd bodysuit produced nothing, of course, yet Luce's saliva and fluids had already left Sonia's thighs slick and glistening.

Remembering the method, Luce pressed her thumb firmly against the lewd clitoris that stood out in a clear outline beneath the white bodysuit, while she suckled and slurped at the opposite nipple.

She clung to one breast and, with her free hand, lovingly stroked the nipple she had already chewed full of affection, caressing both at once.

She had expected the latex to tear or thin out even a little, yet no matter how she bit or pulled, Sonia's ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠lewd nipples only grew harder inside the bodysuit that sheathed them. If it had been ordinary fetish gear it would have ripped long ago, but just as Sonia had said, it was clearly armor.

"Even sooo… sexy is still sexy… Soniaaa…♡"

"Please proceed with the programming sequence…♥."

Sky City's D-class hero, Lewd Drone Sonia, mechanically repeated the same line without variation.

"…Fine. Lewd Drone Sonia… Soniaaa…♡ I'll do it… if I just do it, right…? You want to become a Sonialoid that badly… don't you…? Is that it… you pervert♡"

Staring at the lewd switch, soaked and gleaming with lubricant against the glossy latex sheen of the bodysuit, Luce grinned to herself in anticipation of what was about to happen.

Just like the treasure chests and precious experience points that adventure and dungeon-clearing brought, Luce's heart began to pound.

"Please proceed with the programming sequence, Master."

"I… I'm really… doing this… Luce… Sonia's begging me to, so… I have no choice… Pervert Luce is… with her inverted nipples… going to take Sonia's erect nipples… like this…♡ Master Luce's inverted nipples are going to devour them…♥"

Luce, who had once felt hollow inside like an empty heart. Luce, who could never understand the other adventurers striding so eagerly toward the Succubus Salon. Something was slowly welling up inside her, filling her with an emotion she could not name.

Slowly, she brought her hand to the cheek of Programming-Mode Sonia, who kept repeating the same words.

Chewing, sucking—Luce's breasts were ready to receive, with her own inverted nipples, the lewd erect nipples she had already bitten stiff and hard through the latex bodysuit.

Trembling at the warmth she felt on Lewd Drone Sonia's cheek, yet determined to leave behind the Luce who had known nothing, she pressed her lips to Sonia's sweet-scented mouth.

"Please issue the programming comma—"

…♥

A strange kiss that felt sweet, just like Sonia, who had been thoroughly educated into a lewd drone. Far from resisting, the lewd drone in programming mode was completely defenseless; Luce began to use her exactly as a drone should be used—like a perfect tool.

Her breath came out rough and ragged. Luce's entire body shuddered in fine tremors, yet those tremors sprang from neither fear nor hesitation.

A few strands of her sweat-damp teal hair clung to her forehead, deepening the flush of excitement on her cheeks.

"…Haa… haa…♥ I'm going for it just like this. Sonia…! Ugh… Lewd Drone…! That's an order! Instead of that unstable spider-leg method… from now on…♥"

Luce's voice was hoarse with boiling excitement, yet the will inside it was steel-hard.

Straddling Sonia's voluptuous body, Luce felt a dizzying satisfaction at the fact that her own small frame was completely dominating this huge, beautiful being.

The sensation of dominating someone. The sensation of using them however she pleased. Both were addictive pleasures she had never experienced before.

"Turning Sonia into a Sonialoid… only happens when I, Master Luce, do it like this… so absolutely! You must never transform just because someone else pulls on your nipples. Got it!?"

Before the words had even finished, Luce bent her upper body deep. There was only one target: the stiffly erect nipple switch thrusting through the smooth surface of pure-white latex that covered Sonia.

Luce's large, soft breasts settled over Sonia's full, springy E-cup breasts.

At last, Luce's shy inverted nipples locked onto the tips of Sonia's rock-hard erect nipples like a precision-aimed key.

A firm press—flesh against flesh, with only thin latex between them, sinking into each other. It was no mere contact. It was a method of branding a new rule, a new relationship, deep into Sonia's mind.

It was midday in the apartment, just past lunchtime. Outside the window came the peaceful chatter of Sky City Academy students heading home.

Inside Unit 102, however, a contract of the sort that would only be sealed in the deepest, most secret rooms of a succubus-run establishment was being executed in real time.

The innocent country-born adventurer Luce and the hero Sonia who had awakened to the pleasures of corruption. Their private, lewd ritual was now racing toward its climax.

"Hngh…? I-It's going in… again…♥"

A stifled moan burst from Sonia's lips. Even with every emotional expression suppressed by programming mode, the instinctive pleasure that seemed to pierce straight through her brain could not be hidden.

That unforgettable sensation she had already experienced once. The bizarre, ecstatic feeling of her own hard nipple forcing its way into Luce's soft, warm inverted nipple began all over again.

The tip ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠of her nipple, made even more sensitive by the thin latex coating, dug into Luce's delicate, bashful flesh.

At the sensation of something gently tapping, tapping against the deepest hidden place—the head of her erect nipple—Sonia's breast trembled softly.

As if it had found its proper place and fitted perfectly, Sonia's nipple swelled once more, as though it still had strength left.

It expanded obscenely, determined to fill every last microscopic gap remaining inside Luce's inverted nipple, achieving a perfect physical union. Like a single component locking into place.

"Ugh… th-this… Soniaaa… it's an order… so keep your head clear… and engrave it… deep…♥"

From the center of their joined breasts, an unidentifiable sensation spread outward in waves. The feeling of the lewd switch of the Sonialoid Luce herself had created activating inside her own body.

That sensation made the insides of Luce's thighs twitch and tremble.

It was pleasure ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠like sweet electricity racing through her entire body. Luce gripped Sonia's full breasts tightly with both hands so the connection would not slip, and pressed her own thighs firmly between Sonia's legs as well.

The more tightly they pressed together, the slicker and wetter the space between their thighs became.

"It's an order… so remember this… Soniaaa…♥"

The urge to dive onto Sonia's plump lips right that instant and freely savor the cute, sweet sounds spilling from them surged up like a volcano.

Luce barely managed to cling to the thread of reason. Right now she had something far more important to do.

Just as the Sonialoid had advised, she had to completely overwrite the incomplete, dangerously unstable existing trigger with something that belonged only to her—something safe and lewd that only she could activate.

Focusing every nerve ‍‍‌‌⁠​​⁠‌​​‍​​‍​‌​⁠‍‌‍⁠⁠‌⁠‌‍‌‍‌‌‌‍⁠​‌​‌​‌‍‌‌‌⁠‍​​‌‍⁠‌‌⁠⁠on their joined breasts, Luce began to whisper the new rule directly into Sonia's mind. Her voice trembled, yet the command within it was absolute.

"From now on, Sonia… Sonia only enters Sonialoid mode when her nipples are fitted into my… my… ugh… Master Luce's inverted nipples…"

"Not some stupid drone that transforms just because any random person pulls her nipples… ugh… uuugh… I… I sound like such a pervert…"

She would completely erase that clumsy, dangerous suggestion that let anyone yank her into a strange state.

And overwrite it with a new command.

Only when Sonia's erect nipples were fitted into Luce's own inverted breasts would the Sonialoid activation switch be pressed. Not some bothersome folk remedy like spider legs, but by reverse-engineering the remnants of the "lewd drone" still lingering vaguely in Sonia's mind, she would create her own perfect, loyal doll. It was Luce's own act of creation—remaking the Sonialoid.

"—And after that… while the nipples are fitted like this… fi… fitted… in this fitted state, only when Master Luce says 'Lewd Drone Sonia Mode' to Sonia does she switch into programming mode, okay? Not like I'll ever need to change it anyway? …Probably? Uuugh… that's it. Done! That's the end…!"

Because she had stripped off her skirt before entering programming mode, Luce was already wearing nothing but a single pair of cute striped panties.

While her special "overwrite" command was being branded into Sonia's mind, the center of Luce's panties trembled and grew uncontrollably wet, until at last it left a clear, dark stain right in the middle.

Inside Sonia's mind, a chaotic storm of data raged. The existing "Drone Protocol" and the new "Sonialoid Rules" Luce was injecting collided violently.

A system warning flashed red inside Sonia's mind, yet the Master's authority was absolute. The "lewd drone" data implanted by the VR device crumbled helplessly before the new protocol called "Sonialoid." This was not deletion—it was an update.

If Luce had acted half-heartedly, the "lewd drone" suggestion remaining in Sonia's mind might have faded away naturally after just a few days of neglect.

Luce did not do that. Like a hacked transforming heroine groping her own body freely out on the street, Luce dug even deeper into Sonia's mind and shook it violently.

As a result, the two different personality data sets mixed together in a strange yet perfect blend, like orange juice. This was the moment Luce's very own Sonialoid—now inseparable—was born.

Now Luce input the final keyword.

"It's inside the inverted nipples… so it's in… now… it's Sonialoid's turn! Wake up!"

That suggestion pressed the final switch inside Sonia's mind. The confused, tangled "Lewd Drone Sonia" obediently handed over the body's control stick—which she had received from the "real Sonia"—to her new master, the "Sonialoid."
