BAD ENDING 002: OL Drone Sonia — The Control Switch
It was far too flimsy to call an idea. Little more than a patchwork of everything the lewd drone before her had so helpfully explained—but for Dr. Yuri right now, it was the only lifeline she had.
If this keeps going, I'm headed straight for prison...!
Whatever happens, happens! Dr. Yuri made up her mind. With the last of her strength, she slapped Sonia's inverted-nipple breasts with her palm—a sharp, audible smack.
The unexpected stimulus made Sonia flinch and shyly cover her chest, and in that instant Dr. Yuri seized the opening, wrenched herself free, and slipped around behind her.
Without hesitation, she seized both of Sonia's enormous breasts at the root with both hands, gripping hard enough that resistance would be impossible.
With a hero's physical ability, Sonia could have shaken her off in a heartbeat. But a thoroughly trained lewd drone would be programmed to prioritize her Master's desire to use her over any impulse to serve.
"I am not doing this on purpose… so please try to understand later, Sonia!"
"Kyaa~ Master…♡ Finally… are you going to use lewd Drone Sonia? Ah… ah… a… aaah? Ma… Master…? Hah… heuk…? Hehh…♡"
The prediction was dead on. Far from resisting, Sonia poured out ecstatic moans at the stimulation from behind. Dr. Yuri was desperate.
With one hand she kneaded the pink areola around a nipple that hovered just shy of emerging; with the other she slid down and began teasing Sonia's clitoris through her already-soaked panties.
The wet, scorching heat she felt through the leggings sent an involuntary shiver down Dr. Yuri's own spine.
"Master is… di… rectly…♡ Thank you… lewd Drone Sonia is so happy…♡"
Terrified that the moment she stopped caressing, Sonia would spin around and pin her, Dr. Yuri kept her hands moving with frantic determination.
Sonia simply laid her own hands over the ones gripping her breasts, savoring that warm, rough touch and nothing more.
"Clit… masturbation… is this what it's like… Master…?"
Sonia moved her left hand on her own, crushing and pressing her inverted-nipple breasts the way Dr. Yuri's hands had done. The nipples still refused to come out.
This is Drone Sonia's… the control switch that only gets erect for Master…♡
If this had been ordinary Sonia, those hypersensitive nipples would have been hard all day from nothing more than brushing against a rough floor.
But this was lewd Drone Sonia. She was consciously shutting down every sensation in her chest, straining with everything she had to keep her nipples inverted.
"Lewd… is this it…? Lewd Drone Sonia Mode Active!"
In a trembling voice, Dr. Yuri shouted the keyword that had been circling in her ears.
"Yes, Master. Activating Drone Sonia Mode. Please manage Sonia with Drone Sonia's control switches…♡ Ju… just a moment… please wait… Master… Nipple erection… commencing…♡"
Well of course—I'm lewd Drone Sonia… my control switches only get erect when Master says 'Drone Sonia Mode Active'… Nipple erection mode. Starting now. Master.
The instant the words left her, Sonia's body went slack in Dr. Yuri's arms.
Dr. Yuri instinctively pulled her frantically kneading hands away. She tensed, half-expecting Sonia to lunge again for that strange kiss—but the reaction was nothing like she had feared.
"Master… look…"
Sonia slowly turned to face her. She did not pounce. Instead, for Dr. Yuri still half-sitting on the floor, she arranged herself into the perfect posture drilled into her inside the virtual reality—so that her "control switches" would be fully on display.
Both arms rose above her head, presenting her ample breasts to their fullest.

"Nngh… lewd Drone Sonia… control switches… activating…♡"
With Sonia's declaration, an unbelievable sight unfolded. The pink nipples that had been bashfully tucked inward began to rise—slowly, so slowly—like tiny buds unfurling into bloom.
Minute muscles beneath the skin contracted, drawing the areolae taut, and from their centers the nipples twitched and pushed into view.
In perfect time with her voice, Sonia's body executed a protocol as precise as any machine.
Even the simple act of lifting both arms overhead was calculated to perfection.
Raising her shoulders expanded her ribcage, thrusting her full breasts even more prominently forward—the optimal angle for exhibiting her "control switches" to Master.
Until now, "lewd Drone Sonia" had consciously blocked every sensation concentrated at the tips of her breasts.
To prove she was a perfect component that responded to nothing without Master's command, she had forced herself to ignore the brush of air across her skin, the faintest friction of fabric, even the tremor of her own heartbeat. Now the activation command had been given.
Sonia tilted her head slightly and looked down at her own chest. Inside her mind, the footage she had drilled countless times in virtual reality began to play.
Nipples shamefully inverted, twitching and vibrating, then rising hard as little pegs. The moment that image—submission and pleasure braided together—surfaced, her body answered at once.
No physical stimulus was required: no pinching them out with fingers, no massaging the areolae. On command and imagination alone, Sonia's body began to transform itself.
…sshk… sshk… squirm…
The change was minute. At the center of each pink areola, the inverted point writhed like something alive.
Something seemed to push upward from within, again and again, until at last the hidden nipples shyly lifted their heads.
And that was not the end. Once free, the nipples kept rising—harder, firmer still. As if saluting Master's gaze, Drone Sonia's lewd switches advanced toward perfect erection.
"Haah… huu… haah…♡ The control switches of lewd Drone Sonia who can't do a thing once her nipples are grabbed…♡ Drone Sonia Mode… activation complete… Master…♡ Next, switch lock processing… will also be performed…"
"S… switch lock processing…?"
Dr. Yuri echoed the words without meaning to. The unreal spectacle before her eyes was something her brain refused to process.
"Yes! I'll keep lewd Drone Sonia erect so Master can manage her more easily! Just a moment, Master!"
Sonia answered brightly and brought her hands to her own breasts. Dr. Yuri's mind was pure chaos.
What kind of program—what kind of horrific "education"—could turn a girl who looked this fragile into someone who could erect her own nipples by thought alone, without a single touch, and present those stiff, jutting sex organs before her eyes without a shred of shame?
"Haah… like this… squeezing the nipples up… pushing them up…♡"
Sonia's hands moved with a professional's skill. Starting from the undersides of her springy heavy breasts, she gathered the flesh and swept it upward as if milking a cow.
The pressure concentrated gradually toward the areolae until every bit of force gathered at the tips of the already-hard nipples.
"Right… erect nipple… confirmed…♡"
Report complete, Sonia repeated the identical motion on the other breast.
"Next, left… erect nipple… confirmed…"
The words were barely finished before her freed fingers slipped without hesitation into the gap of her soaked panties and began rubbing with wet, squelching sounds.
"Haah… nngh… ahit…♡ Control switch erection confirmed. Master… my body keeps getting hotter… the lewd drone's control switches, sticking out and completely defenseless… please 'manage' Drone Sonia, Master…♡"
"…I'm just putting them back the way they were… so don't… sue me…"
Dr. Yuri swallowed dryly and muttered. She stretched out a trembling hand toward Sonia's lewd nipples—now so swollen that even the areolae flaunted their presence.
Hard little buttons that had popped free of the areolae with a soft pok. Dr. Yuri pinched one between thumb and forefinger, as if pressing a switch. Then she pulled.
"Ah… aah… if you pull them like that…♡ Lewd Drone Sonia's nipples… come right out…♡ Once they're pulled… I can't… do anything… at aall…"
The switch depressed, and every ounce of strength drained from Sonia's body. Like a machine whose power had been cut, she toppled slowly backward.
Seeing it, Dr. Yuri gained her certainty and did the same to the remaining nipple—press, pull. Sonia was completely neutralized.
—chew, chew…
—chew, chew…?
In a flash, a shameful fantasy streaked through Dr. Yuri's mind. The urge to take those hard, jutting nipples into her mouth, roll them with her tongue, nibble and torment them with her teeth. The twisted desire to hear exactly what sounds Sonia would make while she cried.
"…Hah?! What was I just thinking…?! Deep breaths… deep breaths… one wrong move and my life is over… Yuri… you finished grad school… at least break even… come on…"
When she came back to herself, Dr. Yuri's back was soaked in cold sweat. She had no idea how long she had been staring, entranced, at those E-cup erect nipples.
"Haah… haah… Master… Master…♡"
Even sprawled powerless, Sonia's hands were still busily caressing between her own thighs.
Protocol-engraved behavior, meant to keep the "management switches" at peak erection. When Dr. Yuri pulled them herself, a region Sonia's lewd fantasies alone could never have reached was laid bare.
She had drawn them out far enough that the faint milk ducts between the stretched areolae and nipples were almost visible—and even Dr. Yuri had to marvel at the perfectly formed teats that emerged.
These… just a moment ago they were inverted… and they got erect this easily… put them in my mouth and chew… wait?! Thinking that again… I have to do something, fast…
"…"
"Yes, Master. Please twist lewd Drone Sonia's control switches and speak. Please… program Sonia… Master…♡"
"…All right… just please don't sue me later, Hero Sonia…"
The moment both nipples were in Dr. Yuri's hands, Sonia went completely limp and lay flat on the living-room floor. Only her chest remained, mounded toward the ceiling for convenient "management."
The plan was simple. This wasn't brainwashing—it was self-suggestion. Twist the nipples to enter programming mode, tell her the roleplay is over, and everything would end.
"The nipples… I twist them, right…? Nipples… twist the nipples… and then… then…?"
Dr. Yuri steeled herself—and twisted Sonia's clitoris hard.
"Hngguh…♥ nngh… nngh… ah… hngh…?!"
…The clit…?
Dr. Yuri recoiled in horror at what she had done without thinking. The hand that had been aimed at the nipples—how? A hazy, drunken feeling; a body soaked in sweat and love juices. Sonia's pheromones were paralyzing her reason.
No… why am I like this…?! Th… this time for real…!
Dr. Yuri took a deep breath and, this time, correctly seized Sonia's erect nipples and twisted them hard. Exactly as trained, Sonia did not make a single sound; her vacant yellow eyes slowly closed.
"…Entering programming mode… Please engrave indelible command phrases into Drone Sonia's heart… Master…♡ Once you have spoken every command, please twist the nipples again."
Sonia's eyes shut completely. She lay as if asleep, hands folded below her navel in a perfect standby posture.
Did I do it? Dr. Yuri exhaled in relief and brought her lips to Sonia's ear.
"Haa… huu… The drone roleplay is over! Sonia! Thank you for using our stress-management device! The program is finished, so please return to being Sonia!"
"…Yes. Drone Sonia returns to being Sonia… The program is end…"
…? Was that it? It felt far too hollow. Ending it here left her terrified of the aftermath. Compensation claims, mental-data leaks… countless scenarios spun through Dr. Yuri's head.
One possibility took hold of her. A perfectly controllable, optimal mental-data measurement sample.
"You nearly… got badly hurt… but I helped you… so taking a little… compensation… is only common sense… right?"
The hand that had been about to twist Sonia's nipples to close the command input froze in midair. Dr. Yuri's eyes went cold.
A perfect human who believed she was a drone—and was programmable. A hero, no less. The corner of Dr. Yuri's mouth slowly curled upward.
"Sonia… from this moment on…"
