[Roboticization, Role Reversal, Purification]
"Do not resist, Human."
It was hard not to resist when faced with a one-two-three punch of insanity. Especially when the one telling him to stop was part of that very same insanity.
All that the young man had been doing, before the world decided to triple-backflip into terror, was battle with his digital partner. She had been there by his side since he had gone to this world. Growing from a lil' sprout to a great big rose, yet maintaining a positive and sweet outlook thanks to how he had raised her.
Even if she was sexy, he didn't really pay attention to those parts of her. Because she didn't make use of those parts either. She fought with her skill and her abilities, not with her body. And yet...
While she was busy fighting another one on her level. While she was busy putting the smackdown on the enemy, wrapping her thorny whip around them and readying for the finishing blow...
The world that they were in began to pulse. And the next thing they knew, their opponent was no longer just as big and as dangerous as her. No.
She was worse.
He didn't even get the chance to call out to his partner before the enemy had gone on the offensive. Leaping out from her binds, and forcibly kissing his partner. All while spreading what seemed to be a virus. A virus that...
A virus that started to eat away at his partner. No matter how much he screamed, no matter how badly he wanted it to stop, there was nothing he could do. His partner got further and further converted in front of his very eyes. And she wasn't even able to reach out towards him to try and comfort him in this darkest hour...
Bit by bit, his precious partner vanished. Her adult body shrinking to a much sleeker and younger and compressed form. A form that lacked a lot of what made her distinct. Replaced with a metallic sheen, as she looked much more patched together rather than anything else. An infinite mess of mechanical material, in the form of a young girl...
A young girl who turned her gaze towards her former partner once she had been released from the kiss. And instead of happiness like usual... Instead of sadness at having lost, or anger at having been outsmarted...
The only thing that he found on the face of that mechanical girl was a lack of emotion. All besides the hostile glare from her bright red eyes, and the clear hint that she wanted to do something to him.
It was why he ran. It was why he ended up in this dead end. The way out of this world had been sealed. And his partner...
His partner was approaching. Every deliberate step sent out a distinct clank as she came closer and closer. She had let that warning carry itself through the air, and yet he couldn't truly believe it. He couldn't believe that she would do something like this, even if she was infected by some sort of mechanizing virus.
"You... Y-you don't have to do this, Lily..! You're not a mechanical mess! You're my partner!" The boy cried out as he pressed himself up against the wall. The bond that the two of them shared was strong. He knew that too well. But that was exactly why he was using it. Trying to make her open her eyes..!
'Lily' did not stop approaching. No, she didn't even react to his appeal towards what he perceived as her soul. She just kept walking. All while her gaze was laser-focused on his eyes...
"Your words will not reach." She said, right as she stopped in front of him. "This body has been taken by Mugen. This body's prime directive is to manage Humans like you." Even after clarifying what had happened, that didn't do anything to help the boy.
If anything, now that he knew that Lily was gone because of this Mugen, he felt a sense of despair that was even more smothering than he ever could've imagined. He just wanted to wake up from this nightmare and see his partner smile again. But instead, this girl...
A sharp moan left his lips. He couldn't even look at her in despair before she had begun to carry out her duties. Only after managing to pull his head back down to focus on what was going on down below did he see what she was doing...
Lily... Or the virus using her body as its own... whichever it was, had wrapped her fingers firmly around the bulge in his pants. The effects of what she did were rapidly apparent too, as his crotch began to throb with such an intensity that he couldn't believe his eyes.
He hadn't really been feeling this way towards his partner. So for her to force this out of him so quickly... W-Was she just an expert at this, or...
M-Maybe there was something about her naked mechanical body that was turning him on. Maybe it was that flat chest. Maybe it was her surprisingly wide and squeezable hips. Even if he didn't know how they felt just yet. Just that he thought that either of those parts of her could be the reason why she was able to make him this hard this fast...
"Confirmed. Sizable package and sizable supply. Commencing harvest."
The boy didn't get a chance to stop her from pulling his pants off, nor did he get a chance to stop her from removing his underwear, revealing his surprisingly big cock to the world. Not that she was bothered or entranced by the size.
No. She just took it into her mouth like it was nothing. Her wet and warm mouth, which seemed to immediately wrap around the shaft inside. As if she was not only sucking on it with the same intensity as a vacuum, but also trying to wring everything out of him. Despite the fact that she had only just begun...
The boy was... The boy was helpless. Letting out cry after cry of potent pleasure as Mugen made a complete mess of his cock. It didn't take much for him to start cumming when faced with something this overwhelming. And once he started, the cum just started firing harder and harder. More and more of that incredibly important seed...
Just firing straight into a machine that didn't care for him. A machine that just glanced up at him in between ejaculations. Seemingly counting the amount that he was firing, as well as the amount of times that he climaxed. It was all a process to her. It was all just a process...
It felt so impersonal. It felt so unnatural. And yet here he was. Cumming wildly like his life depended on it. Cumming deep into the throat of his corrupted and controlled partner. He couldn't even cry in despair because of how good it felt, the sheer act of cumming this hard being far too taxing on him...
Eventually, however, he wouldn't be able to cum any longer. And from there, Mugen started to pull off his cock. Seemingly satisfied with what she got out of him. Seemingly satisfied with watching him trembling in anguish as she pulled off, with the boy falling onto his knees now that his legs gave out.
"Harvest complete." She said, her eyes spinning slightly as she processed everything that she had swallowed. To give it a rating, and determine if she should return... "Processing complete. F rank. Goodbye."
Just like that. She began to leave. Given the words that she had left him with, there was a high chance that he would never get to see her again. And even if she didn't resemble Lily any longer... Even though she was nothing more than a seemingly mass produced virus-infected menace....
He just couldn't let her go. Even with his legs screaming at him to stop moving. Even with his cock having long since reached its limit. Even when he knew that she could kill him if she so wanted.
"Lily... Lily... LILYYYYY!"
He wasn't going to let her go!
Mugen narrowed her eyes as she attempted to turn around and blast this Human for showing resistance. But that moment was all that Lily's partner needed.
He was just fast enough to stop her from whipping around. All thanks to how he had literally thrown himself onto her, pinning her underneath his body. Even if she was stronger than him, pinning her like this would give him an advantage...
"Remove yourself." Mugen said, her body starting to heat up in response. She could throw him off, yes. But burning him with her heat was more convenient. And it would be justified in response to how he had treated her.
"LILY!"
But she didn't get to heat up enough. Not before she felt something thick slide in between her cheeks. She was not aware that she had a hole back there. She was also surprised that he was able to find it, and penetrate it with such intensity. She thought that she had drained him of every drop of cum.
And yet here he was. Ramming his cock into her hidden hole. Ramming with an intensity that she couldn't have calculated or predicted. She didn't understand how or why he was able to go this hard...
Much like she didn't understand the pleasure that came with this intense state of intercourse. Was she getting aroused? Was she starting to enjoy having her rear filled with human meat like this? Incomprehensible... Inconceivable..!
"Lily... Lily! Lily, this feels amazing..! You have to enjoy this too..! Fight back..!"
Her former partner, meanwhile, couldn't believe how good it felt. It was a bonus in the grand scheme of things, but one that was definitely appreciated as his meaty thighs slapped against her plump metallic posterior.
He didn't fuck her because he wanted to feel good. No. He fucked her to try and get his partner back to the surface. He wanted to make his partner return. He wanted her to look at him again with her usual smile..!
And he'd fuck her. As hard as he could. To fuck her right back to normal. Fuck the virus out of her and bring her back..! Thrusting his hips harder and harder forward, to ensure that the bucket of bolts that she had become could be overpowered! So that she could be with him again!
Mugen's eyes were rapidly spinning as they grew redder and redder. This was all against her calculations. This was against any sort of predictions that she had made. How was the Human still able to fuck this hard? More importantly, how did he believe that she would be able to return to normal?
...Return to... Normal..?
Several error noises echoed through the air as Mugen's mind was starting to fragment. All thanks to the intense love that the boy was putting into his thrusts. He was doing everything he could to make his partner return. And it was that everything that was affecting her, making it harder and harder to keep herself together.
The pleasure... The pleasure..! It was-
"LILY! I'M CUMMINNNGGGG!"
A mutual cry of overwhelming pleasure echoed out. One human male's intense orgasmic scream. One mechanical female's equally intense scream. The emotions, or lack thereof, started to merge together as a brand new flood of cum spurted forth. All while the virus-infected girl couldn't stop twitching in response to having her rear inseminated with such a hot river of seed...
Her connection to this body was growing unstable. All thanks to a little bit of cum? No. It wasn't just the cum. Upon further analysis, there was something about the feelings poured into it. Poured into her as well...
The mechanical girl didn't understand. Nor did she understand why several error sounds went off inside her ears as she locked eyes with the boy that had plapped her, once he turned her onto her back...
"Lily... Lily, I love you... I'm going to fix you, just you watch..!"
She didn't understand. What was this love? How was it able to overpower the Mugen virus? And why did the sound of his love make her feel all sorts of fluttering sensations.
Mugen didn't understand. Couldn't understand. All that she could do was cry out once again. This time because he pulled out of her, and then rapidly slammed his shaft into her virgin vagina. Spreading it wide, all while he put everything into his thrusts once again.
It felt good. It felt really good. She was a mechanical being. A virus that claimed a body that was meant to help her propagate. And yet... And yet she was experiencing a rush of pure euphoria. Unlike anything that she ever could've calculated.
The way that she was being fucked was intense. It was overwhelming. And yet it also felt so good. It felt wonderful. And it only grew more wonderful and potent as she locked lips with the boy. The boy that wanted his partner back. The boy that was fucking her for the sake of getting her back...
Mugen had never experienced something like this before. And as the rush of pleasure that came from such a love-filled fuck kept on filling her, she couldn't stop what came next. The overwhelming pleasure that would bring even the mightiest to their knees...!
What did he call this sensation..? Ah... Yes... Yes, that was it... She was... She was..!
"CUMMINGGGG!"
Once again, the boy and the virus cried out in unison. Their climax reached new heights. New decibels, as the very sound of their climax very nearly destabilized the world around them. It was destructive and overwhelming. And yet intimate and loving at the same time...
Mugen had never experienced anything like this. And even as she was being destroyed by how good it felt, her body gradually started to destabilize and return to a more organic form. She couldn't help but want more...
Even as the very last speck of metal vanished from Lily, restoring the rose-haired girl's body to normal... Though not restoring it to the same size it had once been...
"P...Partner..?"
The boy panted and gasped. Overwhelmed by how much he had climaxed. But as he slowly lifted his head, he was able to gaze into Lily's eyes once more. And his heart... His heart was so happy that it could burst...
"Lily...! Lily!" He cried out, hugging her the best he could. Coughing a little from everything he had put into this fuck, but it didn't matter how much he had pushed himself. As long as she was there for him...
Lily smiled in turn. Even kissing him on the cheek. All while giggling a little, sounding just as cheery as she usually had. "Thank you, Partner..." She whispered into her ear, kissing him on the cheek as she did...
He was happy. For about a split second, right before a rush of heat went through him, and he locked eyes with Lily once again. Thankfully, he didn't see the crimson glow from Mugen...
But the look in her eyes was just as dangerous. Because she hadn't been in control before, she wanted to experience what the virus had experienced. Which forced her to pull him closer, their foreheads kissing as she smiled with such a need...
"You better not give up now, Partner."
"Indeed. Show me this passion again. Show me what I experienced."
It was one thing to have Lily beckon him to fuck her. It was another for the virus to echo through his ears. And as he blinked in shock, he found that she materialized at her former host's side. How..?
He didn't know how. All that he knew was that there were now two thirsty tramps that wanted him to fuck them hard. And despite everything that he had already done, they still wanted more...
...
For Lily, and for the Virus that had brought this out in her..?
Even if he was tapped out, if it was for them..!
