BAD ENDING 003: D-Class Lewd Partner Drone Sonia 9 — The End
Far smoother than ordinary bare fingers, the Sonyaroid's glossy white latex digits produced lewd, wet squelching sounds every time they met damp flesh.
Those artificial fingers slipped one, then two, without the slightest hesitation into Luce's thoroughly soaked folds.
When the two fingers pressed together and pushed firmly toward the hard pubic bone just below Luce's navel, the D-class cow-titted adventurer's body gave a fine, trembling spasm.
Her quivering form soon convulsed hard, gushing hot love juices in a rush. That was a biological climax — the phenomenon people commonly called "coming."
The naive adventurer Luce, who didn't even know such a basic fact, and the Sonyaroid, who knew everything yet deliberately kept it from her, intent only on breaking her Master over and over — their twisted service simply continued.
"Nyaa...? Sonyaaa...? This... feels good... feels so good... *chu*...♡"
"...♡"
Luce gasped under the Sonyaroid's relentless, mechanical service, swept away by successive waves of climax.
When she finally forgot how to speak amid those unknown sensations — sensations so foreign she seemed not even to grasp the concepts of being touched or caressed — only then did the Sonyaroid pause briefly to carefully check Luce's condition.
"Feels good...? Feels so gooood... more...♡ Sonyaaa..."
The Sonyaroid gently stroked down the insides of Luce-nim's thighs, slick and gleaming with sticky love juices.
She hadn't even touched Luce's nipples or pussy directly — merely scraped the river of juices running down her thighs with the edge of a glossy latex hand — yet Luce twitched again. Watching this, the Sonyaroid offered a satisfied smile and a single remark.
"Luce... Luce-nim, aren't you completely soaked down here...? ...The Sonyaroid is... so happy that Luce-nim is enjoying her service♡"
"Sonya? ...Sonyaaa...! It's Sonyaaa...♡ Heuk...♡ Peeeh...♡"
The Sonyaroid deliberately rolled Luce's clitoris gently with her fingers, then slowly lifted them away.
When the fingers that had been delivering that pleasant feeling — the sensation the Sonyaroid had called a "yummy feeling" — pulled back, Luce instinctively chased them.
She became the unconscious picture of a female in heat, slightly thrusting her lower belly forward as if to lift her lewd lower switch and bring it back into contact with those fingers.
The thought of reclaiming the initiative from the Sonyaroid's service never even existed in Luce's mind.
She had long since become a vending machine that only poured out sweet love juices — like a pet doll the Sonyaroid merely fondled, her common sense scrambled into a mess whenever she was pressed or pulled.
The ticklish pleasure gradually gathered at the center of her lower belly, twitching... twitching... This time Luce deliberately steeled her heart, following the command the Sonyaroid whispered into her ear: Don't come — keep holding it in... please, Masteraa...♡
Luce had only just learned with her own body what climaxing — what coming — actually was.
"Sonyaaa... huu... Sonia... hngt...♡"
Steeling her resolve, Luce accepted the Sonyaroid's new common sense wholesale: The longer you hold back a climax, the better it is...♡
She was desperately holding on, yet the Sonyaroid still dabbed up the clear, sticky love juices seeping out and thoroughly soaking her underwear fabric, then carefully coated Luce's stiffly erect nipples with them as if applying a glaze.
"Ahat... Sonyaa... my nipples... ticklish...♡"
It wasn't fetish gear so much as high-performance defensive armor — a premium-grade bodysuit. True to the word "premium," it clung perfectly to Sonia's body, revealing every curve in fine detail.
From her lewdly protruding nipples to the shape of her navel's interior. Though covered in latex, the Sonyaroid's nails still stood out clearly as they gently scratched the underside of Luce's erect nipples — the most ticklish-looking part.
While scratching beneath the nipples as if teasing her own creator, and while Luce accepted it as yet another new caress and felt it, the Sonyaroid pressed her own breasts firmly against her.
She aligned the tips of her own erect nipples — covered in the glossy bodysuit — precisely against Luce's lewd nipples, which had become so stiffly erect it would be hard to return to their former inverted state.
"Since Luce-nim likes it, the Sonyaroid is happy too...♡ That happy face...♡ Ah...♡ I feel like I'm going to come again... come? Yes... come just like that... come, Luce-nim...♡"
"Huaaa... ahh... kyuuu..."
The Sonyaroid pushed her sticky latex fingers back into Luce's folds. Starting from the fingertips, she began stirring inside Luce-nim — all to serve Luce-nim perfectly.
She pressed the tip of a nail firmly into a nipple tip, pushed hard enough to leave a mark, then twisted slightly sideways — and a sweet sigh burst from Luce's lips.
"Do you see, Master? Ah... ah... She's completely lost her mind. Master... even when I poke her nipples like this and then press them hard the other way... now that they're no longer inverted nipples... I was going to congratulate you, but... the Sonyaroid is sad..."
Luce's knees and elbows, having already forgotten every rule, trembled finely. Coming... please come...♡ The closer the moment of climax approached, the stranger the tingling sensation that seemed to wrap her entire body. And the Sonyaroid never missed those physical reactions of Luce's — the cries of that lewd cow-tit.
"Your knees... are shaking, Masteraa...♡ Good... come just like that... please...♡ Eiit...♡ Show the Sonyaroid every last bit of Luce-nim coming...!"
Gazing lovingly at the trembling Luce, the greedy Sonyaroid monopolized every corner of Luce's mouth.
"Haat... haa... huu... haa... het... he... at... a... aaat...? Huaaaaah! Heuuuu...♥ ...Hek...? Het...?!"
...Thud.
Sonia was an ordinary human with no extra components like built-in batteries or power sources — only her navel slightly modified into a neural connection plug port. The Sonyaroid controlling that body collapsed powerlessly, like a computer overheating and throwing up an error screen.
The strength drained from the arms that had deliberately been supporting Luce without weighing her down, and she toppled straight onto the ample breasts of her lewd cow-tit Master Luce-nim, who had been half-fainting under the Sonyaroid's caresses on Sonia's bed.
"Eheh... Sonyaaa... it's Sonyaaa...♡ Good Sonyaro... came back... uh♡ ...Kuuul..."
She collapsed onto those generous breasts — the very ones that always got her hounded for extra fees at the blacksmith's — and the Sonyaroid... no, Sonia, began to go limp.
"Luceeng... cheeeng... Lucee..."
From her firmly tensed thighs all the way to her toes, every single part of Sonia went soft and pliant.
Luce rolled the Sonyaroid lying in front of her sideways like a big pillow and then chu...♡
She hugged the soft Sonia-pillow tightly in her arms and slowly drifted off to sleep. Tomorrow morning she would have a hard time figuring out what excuse to give Sonia, but for now she hugged the peacefully sleeping Sonia and slipped into dreamland together.
Whether it was because the Sonyaroid had so thoroughly sent away the "adventurer Luce" she had been, Luce fell into an easy sleep free of complicated worries for the first time in a long while... having finished what was, surprisingly, a first experience that was ordinary in this world.
Today, at least — or perhaps from today on — Luce could sleep soundly.
"..."
"...Scratch scratch."
From the damp, gloomy stone floors of dungeons to the seats on airships leaving Sky City for other cities — where, to cut costs, passengers were frozen and shipped like cargo — Luce the adventurer had slept in places worse than the roadside.
Right now she had been lying together on the bed in the room of a certain D-class hero of Sky City, Sonia — damp, yes, but not gloomy — and now she was sitting on the edge of the bed.
"...It's... lunchtime... right, Luce? ...Aren't you hungry?"
"...Y-yeah... Sonia... let's go out..."
Two people far removed from short-term hunter training schools or skill academies. No scene of them running side by side with strawberry-jam toast in their mouths like a magical girl anime — just E-cup busty girls awkwardly reading each other's faces.
One pair of breasts seemed to have returned to inverted nipples, yet they still trembled slightly now, as if hoping that whenever they were "touched," they might taste yesterday's experience again.
It didn't seem that the trembling was limited to Luce's inverted nipples alone. Sonia sat in the desk chair, and her nipples protruding through the glossy bodysuit twitched, reflected in Luce's pupils. Latex-coated nipples that smoothly reflected the fluorescent light.
"G-going out like this... doesn't seem quite right..."
"Th-that... right?"
Sonia's Association-issued bodysuit was, for all its somewhat exposed appearance, proper defensive armor.
Stains left on the tips of her breasts from the inverted-nipple adventurer in front of her sucking and licking and enjoying herself all over the latex bodysuit, and the crotch area that gleamed as if emphasizing her lewd lower half, its color slightly changed.
"So... *hkk*...! Sonya. What do we do with this? Wash it, or throw it out?"
"Just throw it out and buy a new one on the way, Luce."
Sonia, owner of a flex mindset that simply discarded things once they'd been used enough. Of course, Luce had already folded up the thoroughly soaked bedsheets from earlier and stuffed them into a trash bag.
When she stripped off the bodysuit in one motion, her breasts swayed and bounced; Sonia gently calmed them with her hands, then tossed the Association-issued bodysuit straight into the washing machine.
"Where are we going, Sonya?"
"Hmm... good question? That restaurant you said you wanted to go to last time. How about it? We can buy new sheets on the way too..."
Luce, taking the words that way, blurted "A... again?!" — but Sonia didn't bother answering. Instead she brought up the dungeon talk Luce had been going on about even before the Sonyaroid.
"Or... later... we could go to a dungeon..."
"F-for real. Sonya? Really? Sonya... I love you!"
There had been moments of awkward face-reading when they woke at an odd hour, but the two of them headed out together as if nothing had happened.
If there was one small difference in that ordinary daily life...

Inverted nipple authentication complete♥
Sonyaroid activation initiated♥
Whenever the Sonyaroid was needed, Luce — the Sonyaroid's Master — would insert her inverted nipples like a key into Sonia's firmly erect nipples.
That was the difference.
