BAD ENDING 003: D-Class Lewd Partner Drone Sonia 8
Twitch… twitch…
The tremors that began at the center of Luce's breasts were subtle, yet the waves they created traveled clearly along her nerves, spreading through her entire body with startling clarity.
Like some tiny creature stirring from hibernation, the inverted tissue that had been shyly tucked inside her areolae began a systematic cycle of contraction and release. Her nipples were already swollen to their absolute limit from the Sonyaroid's skilled attentions, yet they still only peeked timidly out as far as the border of her areolae, as if clinging to one last shred of dignity.
It was a pitiful, lewd sight—like a bird's beak hesitating to break free of its shell.
The sensation of them swelling and rising, so slowly it was almost imperceptible. Luce could not even bring herself to touch the nipples that were finally beginning to emerge from the dark, hidden spaces where they had long been concealed. She could only stare blankly, letting out a dazed little "Heeh…" Her adventurer-honed reason simply could not keep pace with the strange, overwhelming transformation taking place in her own body.
Transparent saliva she hadn't even noticed drooling spilled down her chin and pooled in the deep valley of her ample cleavage. Just as thoroughly as the glossy latex bodysuit encasing Sonia's entire form, Luce's upper body was beginning to receive a perfect coating of sticky, glistening fluids. The lukewarm slide of saliva across her skin became a fresh stimulus of its own, dragging her consciousness even deeper into a hazy abyss.
If Luce had thought as carefully as she did when accepting a dangerous commission, she never would have casually synchronized the Sonyaroid's thought patterns with the protocols of "Lewd Drone Sonia." The present situation—this creation recognizing her as delicious prey and lunging like a starved beast—would never have come to pass. Every setting had been input by the Sonyaroid's creator herself. Luce had brought this exquisitely sweet outcome upon herself.
"Luce-nim. I'll serve you."
With those words, the Sonyaroid cast her shadow over Luce's body. Whether the choice of "I'll serve you…♡" instead of something crude and vulgar like "Master. I'm going to fuck you…♡" was fortunate or unfortunate was something Luce—desperately clinging to the last scraps of her reason—could no longer judge. The devoted, absolute nuance packed into the word "serve" cleverly dismantled her final line of defense.
"Mm… I thought pulling them out with my fingers earlier was a bit much, but Master's… not inverted anymore, just regular nipples… looking this delicious, I can't just leave them alone! Time to dig in. Haahp…♡ …Mmph-mmph… pahh…♡"
The Sky City's one and only Luce-exclusive android—the Sonyaroid—latched onto the nipples that had once been inverted, now quivering unprotected and hypersensitive in the open air. Lewd wet sounds of chew-chew…♡ echoed through the room as the nipples were sucked into that hot, damp mouth. Twisted and rolled by the tip of a tongue, Luce could only fidget restlessly, staring down at the Sonyaroid's golden hair.
Already slick and wet, the Sonyaroid's white latex fingers groped along Luce's thighs, heading for her most private place. The options of pushing Sonia away or retreating had long since been sealed off.
Those latex fingers were no ordinary fingers. Micro-sensors embedded in the surface measured Luce's body temperature, pulse, and even the finest tremors of her skin in real time, hunting for the most effective points of stimulation.
"Hweh…? …!..!? Th…tha… wh…where are you sticking your fingers… ah… euh…♡ …Sonyaa…♥"
The wetter the Sonyaroid's fingers grew, the more those once-inverted nipples were sucked with wet chuuup-chuuup sounds, the only thing Luce could do was one: set down the identity of the innocent "Adventurer Luce" who had known nothing, and accept the newly forged role of "the Sonyaroid's Master."

The lewdroid's tongue deliberately forced its way into the crevice between areola and nipple. Under that dense, relentless motion, Luce's full breasts forgot resistance and began willingly surrendering everything.
The Luce of the past who had haggled with the blacksmith over material costs when ordering custom chest pads. The Luce who had found it so curious that Sky City outlets charged roughly the same price no matter the size. Those breasts of hers had now become tools for the Sonyaroid's pleasure.
"Ah… a… ah… Sonyaa…"
The more she stroked the soft golden hair of the Sonyaroid clinging to her chest and trying to swallow her nipples whole, the more lewdly the robot burrowed into every gap, carefully smearing Sonia-flavored lubricant all around the inverted nipples. That gentle petting—stroke, stroke… smooth, smooth—was an unconscious mark of surrender.
As if answering that touch, Sonia's soft tongue made one gentle circuit of the gap between Luce's nipple and areola, layering on more lubricant. When that flicking tongue forced its way between nipple and areola, the areola rose in a goosebumped tension. The Sonyaroid sucked it into her mouth as if savoring the taste, slowly pursing her lips smaller.
From the entire breast down to the areola, from the glossy pink areola to the very tip of the nipple… narrowing her target until at last she perfectly extracted the lewd switch from Master's inverted breasts. Deliberately chewing, she lightly bit the soft yet increasingly stiff nipple that seemed to beg for more torment the more it was teased.
"Hwaaah… Luce-nim is completely soaked… Get wetter… Hehe… Master… all over my fingers…♡ Ahyup… behh…♡"
Like a cat lapping milk from a saucer, the Sonyaroid—configured "that way"—kept licking the protruding nipples with her tongue to savor the sweet taste of Luce-nim, and each time Luce's nipples could only tremble. Simply stroking the Sonia clinging to her chest, Luce fidgeted this way and that under the sensation of inverted nipples forcibly extracted by vacuum-like chuuup-chuuup suction, her thighs slick with nothing but love juices.
More like a baby kitten than a baby, it was devoted breast-service from a Sonyaroid whose common sense had been rewritten to [Luce is delicious! Luce is sweet!]. Luce deliberately hugged the Sonyaroid tighter against her chest with firm presses, but the initiative had long since slipped from her hands.
When the white latex fingers withdrew, creator Luce found herself sinking deeper into the lewd Sonyaroid's breast service. The fingers that had smoothly reached all the way inside her pulled back, and though Luce had wanted to enjoy the breast-suction service even more deeply, she—D-class adventurer Luce—was simply pushed backward by the Sonyaroid still teasing the tips of her breasts with ticklish service.
"Aah…? So… Sonya? Why are you suddenly pushing—hngk?!"
In the nest of Sky City hero Sonia, the Sonyaroid toppled Luce straight toward Sonia's bed.
"Hnguut…?!♥"
Luce tumbled onto Sonia's bed. The soft mattress caught her back, but there was no time to collect herself. With her breasts still being sucked chuuup-chuuup, Luce foresaw a future in which she would one day look up nipple-sensitivity training suckers on the adult video site Nebulix.
The head that had been tilting toward the Sonyaroid while her nipples were being drunk dry now simply arched back, her waist lifting slightly as she began to pant in a posture like a perfectly fried shrimp.
"Just like that—climax. Do it, Master~♡ Here… is it here? Or here? Like this?"
Mercilessly, the Sonyaroid began cornering the Luce collapsed on the bed. Even porters who entered dungeons loaded with safety gear were more vulnerable than a properly dressed D-class adventurer like Luce—that much was obvious. Unlike porters skewered by sharp spider legs, Luce's adventurer durability would end in mere scratches. A sturdy body whose stats from stamina to endurance were on a different level as a D-class adventurer. And the fingers of the Sonyaroid currently occupying the body of a D-class hero Sonia could crush a large cola plastic bottle in one hand.
"Hogooook…?! Hnguuah, ehek… hngiit… eugiit…?!♥"
She hadn't deliberately dressed for it, but there was nothing better for gripping slippery things than a glossy full-body latex bodysuit. The problem was that the object being crushed was not an empty cola can or plastic bottle, but Luce's vaguely erect lewd clitoris.
Press… press…
The Sonyaroid seized Luce's clitoris—so glossy and smooth that even soaked in love juices it still made wet chap-chap sounds without slipping—and, without stopping, twisted Master's lewd clitoris as if turning a doorknob.
"Hek?! Hek… Sonyaa…?! So… nyahng?! Nyaaha… het… heuh…♥"
Before the sensation could even climb from Sonia's finger caresses on her clitoris to the inverted cow-teats being sucked dry, the waist of the Sonyaroid's master and creator Luce rose little by little like a fried shrimp, twitching and writhing.
"Nyahng…? Really? Master suits a cow better than a cat…♡ Look at this, Master! Your breasts are as big as Sonia's but you're short, so you look like a cute little cow… lewd cow-teats…♡"
"So… nyahaa… nyaa…"
Even without being a member of Luce's party, Luce had entered dungeons with all sorts of people. After jobs she had been casually invited to everything from the Succubus Salon to "special" theme clubs and cafés that even Sonia would have found remarkable—Luce of the E-cup cow-teats matching Sonia's size—yet until meeting the Sonyaroid she had focused solely on dungeon clears and experience as an adventurer.
This was her first experience of the kind… and the first person to do this to her had become Sonia, the first person she could call a friend after crossing over to Sky City, leaving Luce at a complete loss…
The sturdy adventurer Sonia—controlled by the Sonyaroid—pressing hard enough to make a sturdy adventurer's clitoris go numb. Not solitary masturbation, but another woman's fingers roaming freely over her body, over her breasts, and Luce slowly began to go limp, surrendering her strength as if offering herself up.
"Sonyaa… good… so good…♡"
Her breasts—once inverted nipples now lewdly erect—were pinched hard, lifted, then dropped with a soft plop and a wobble back into place. Her clitoris rolled by latex long gloves that she hadn't deliberately put on, yet which delivered only a smooth, slippery sensation as if gently chewing and tumbling it this way and that.
"Sonyaa… Sonyaat… Sonya…! There… theree… more… more… heeh… heet…♡"
Luce simply accepted the Sonyaroid's actions that were unmistakably toying with her Master. Far from pushing Sonya away, the pitiful adventurer only clutched the bedsheets tighter, as if she had noticed for herself that the frequency of her twitching was growing faster and lewder.
Rolling Luce's small, short, yet twitch-inducing lewd clitoris like a bead, the Sonyaroid simply enjoyed the reactions of a Luce who did not even realize that trembling and then giving a great twitch meant she had already climaxed.
The breasts Luce had never once permitted to the starving goblins she had faced in the deepest parts of dungeons, nor to the damp and slimy slimes, nor even to the sticky tentacles of unknown origin—those soft, delicate flesh—now lay completely exposed and defenseless before the Sonyaroid she herself had created.
