"Uh, you know we might not be exactly compatible," he replied as Arcee stretched out,
"I am aware, but your armour, does it not allow you to connect to a port? Optimus mentioned that was how you communicated." Arcee paused and slid a hand over her chest plate. It split and inside was a golden sphere, held in place by two long rods. As she moved a hand over the centre, it split again, and inside Peter could see her spark, floating and spinning. "I am willing to allow you access to my spark chamber."
Peter shook his head while taking in a slow breath. "No. Arcee, I have no idea what will happen. Without the All-Spark I could kill you." He moved his hand up to a port directly above it, "What about here?"
"That allows the chamber to be removed, and for a medical officer to check that my spark has not sustained damage. There were tales and legends of Cybertronians who split their sparks in two, and used it to create a companion."
"If I access that, would I risk damaging you?" He asked, and a symbskin glove formed over his hand, while Arcee shook her head.
"I do not believe so. " and she lay down, sliding one arm between Peter's legs as he knelt beside her. "I may move, and this will result in maximum comfort. Are you ready?"
Peter placed his hand over the port, and a small sliver of symbskin covered it.
Arcee glitched as Peter slid into her port. She'd never tried a direct interface before, even though she'd heard the data transfer could be intense and now she wished she had. As his technopathic powers created a bridge between them, her spark shuddered and tingled. She never even knew it could do that but now, she wanted more.
Arcee had never moaned with pleasure before but as his gentle caress glided through her, and her circuits began to light up with the new sensation, she wanted to reciprocate. She had seen others, so she had an idea of what to do.
The human database she had read inferred that the male's genitals or their "penis" was sensitive and she lifted her hand and touched Peter between his legs, "I wish to try more."
As his pants slid away she gently took his manhood into her mouth port. Carefully letting some of her internal lubricant coat it so her filters and dirt traps didn't damage its delicate structure.
Of course, the inside of her mouth was a smooth cold metal and even as she took Peter's cock deeper down than anyone else had ever managed he still kept his symbskin finger in her interface, trying his hardest to contain his lust.
Arcee might be a novice but she activated a gentle vacuum and let the pressure build on Peter's cock, she knew eventually he would release a fluid and she wondered if it would be compatible with her systems. As his finger gently probed she felt it tingle more and more and each time he slid into her she felt the jolt from her spark grow.
Without taking him out of her mouth she activated an external speaker "you may release if you desire" she spoke, knowing soon her spark would jolt one more time and she might have to shut down due to the sensory overload. She would prefer to have him release his fluid before that happened as she was curious if he did contain Energon as Optimus theorised.
Peter could feel the bright spark of energy that was her life force grow each time he slid more of himself into her, he could feel her impatience at his reluctance to finish but deciding that trust was a two-way street he prepared for one final push.
He felt the spark within her pulse out and the emergency system activated, her pleasure circuits overloaded and shut down but before her whole system crashed he came in her mouth, letting the energy-rich cum he knew she was after pour into her.
Where it met her damaged systems they immediately rebooted and reformatted. She purred and he felt her vibrate around him, making him cum again and he enjoyed feeling her drink him down, with the others in the warehouse having a preference for oral he always enjoyed it as much as they did.
Arcee felt the Energon rich fluid infiltrate her systems and her spark sang, no longer glitching it thrummed and every one of her circuits sang in harmony with him. She felt herself reformat but she didn't care, I wonder if it will let me take him more ports? She thought and as the torrent of fluid came to a disappointing end she used the self-cleaning apparatus in her throat, normally used to wash the dirt from her oral cavity, gently clean away the remaining fluid from his penis.
As he stepped back Arcee finished her transformation, the familiar grinding and mechanical noise accompanying her new form. She was still a motorcycle but now she was a slick black and white colour and transforming back into her robot form she was now slightly smaller, only a head taller than Peter but with four new limbs stretching out of her back and a spider motif over her chest. As she marvelled at her new form she realised that she had new blast shields on her body and as they slid back a new surprise was waiting.
Her chest floatation devices, normally used to keep her heavier than normal chaise, had two small nipples, pale grey in colour, on them and to test she gently pressed one. As she let out a moan she slapped a hand over her mouth, was that me? And as she did it again, once more she moaned.
"Uh, human females have those, they're nipples. I don't think you'll be having children though, so they'll be mainly for sex," and Arcee nodded.
She also noted that like a female of the species she had a port between her legs and one just slightly above it, knowing full well what they were used for she shook her head,
"I think you have formatted me to be sexually compatible with your species. Do you wish to engage in more sexual copulation with me?"
Peter grinned and although she was heavy, it was not difficult to lift her, as she wrapped her arms around his neck he lifted and tilted her and slid effortlessly into her.
Arcee glitched immediately, her mouth open in a frozen moan of pleasure, her spark pulsed and spun faster with each thrust. Shrugging, he had no clue if this was normal. He began to slide her up and down his member, and soon she was panting and growling in his ear.
Once her spark had started pulsing rhythmically her systems came alive, she had never felt anything, never heard of anything like this before and she wanted more. She pushed him down and he let her, sank to the floor and Arcee slid him all the way into her, feeling the tip touching something deep inside her.
It was a connection to her spark chamber as they touched she felt him, not just physically but mentally as well, they were connected and even Peter felt it. A primal force that neither of them understood and soon he erupted within her.
Her spark chamber opened and his cum flowed into it, its brilliant blue colour doused in the white creamy liquid but rather than extinguishing it, it glowed more, absorbing it and strengthening itself.
Arcee and Peter both held each other close. Peter's cock raged as pleasure ripped through him and Arcee couldn't move as her spark was not only repaired but strengthened and invigorated. She felt connected to the Matrix of Leadership, she felt connected to every Cybertronian left on earth and through them, she felt a connection to Primus himself.
Her spark shuddered and began to turn a delicate lilac colour as a red-tinged its normally blue colour, it deepened into a darker royal purple and they began to fade into a deep red.
Arcee shuddered and twitched as her spark sent new programming instructions to her systems, new information was taken from Peter and reformatted her once more. She twitched and glitched as systems transformed and changed.
Peter watched as the once smooth metal Cybertronian shifted once more, her form shifting and he saw a symbskin coating form over her, a delicate red colour that matched the pink of her armour.
As the skin slipped out and over her he could watch the physical changes as they happened, joints were smoothed and became more organic, the thick metal plates of her body softened and to his surprise, her chest plate split and became two breasts, human and with very pink nipples that spring out like two spark plugs.
Her limbs shortened and her chest shrunk, metal plates folded and slid inside and she screamed and stretched herself outwards, mechanical parts smoothing and vanishing under symbskin covering.
She huffed and he could see the steam coming from her mouth as she stood and wrapped an arm around her head she stretched and Peter gasped at what he saw.
She was human, or at least a transformer human hybrid. The smooth metal plates now had a red hue but looked like battle armour over pale and creamy white thighs. Her chest was bare and two large but perfectly proportioned breasts sat with delicate pink nipples, as she reached back they bounced softly. Her face was now more human as well, the grill usually in her mouth port gone and placed by pearly white teeth, surrounded by pink lips. She even had hair, and the soft flowing locks were a delicate pastel pink colour, the same as her Autobot form.
Unsurprising as well he could see between her legs a small patch of the same pink hair atop a human vagina, it glistened and as she stretched a pink clit peeked out from between the lips.
Whatever introducing his cum into her had done it had made her more human, or more symbiote, he couldn't decide which. Even Arcee stares at herself in amazement, with now human eyes.
She still had her optics, there was no difference in her interface but now, she could see proper colours and knew what they were, she could smell and now no longer had a display of good or bad she knew herself if she liked it or not. Her body was no longer the living Cybertronian metal she had been built with but now was a mix of hardened armoured plates and soft spinning material that was pleasant when she ran her fingers over it, touch, even her sense of touch was different. No longer registering an exact number she knew that it was soft but not the material molecular density or hardness index.
"You, what did you do?" Arcee based and paused, her vocal unit had also changed, instead of the mechanical sound synthesised voice she felt the air currents move over a new organ and her voice came out soft and silky. "Talk, I'm talking, I can talk" she spoke, laughing as her new voice sounded good to her ears.
"Uh, I dunno" Peter shrugged, he'd connected with her systems and that was as far as he knew. "Made you more suitable for Earth I guess?" and he shrugged.
"Technorganic, I'm now a technorganic life form, I still have my spark, I can feel it but, it's not the same '' Arcee wondered if she could even transform.
Willing the change she felt herself shift. No, she had two forms now, two extra modes as well as her, and she laughed, human form.
"I have a symbiote as well. Reboot, we are Reboot" and as the symbiote flesh covered her surprisingly she looked human.
Her form had pale white skin with two moderately sized breasts, pale pink nipples sat on their centres, and Peter could see while hairless she also had human genitals, the same light pink colour, she lifted and hand and examined it ant was human, fingernails soft supple skin and running her hand over her face and up she felt it, she had hair, a light blonde colour, almost golden in colour and as she ran her fingers through it she whispered, "it's so soft," and Peter smiled.
"Maybe some clothes though, if you're in that form" and as Reboot willed it she changed and stood in a white summer dress. "Perfect," was all Peter said.
"Uh, I don't know if I can still transform though," and willing it, she began to change once more. Her form seemed to unfold, hidden plates splitting the skin seamlessly and she became a more robotic looking transformer once more. The plates melded with her body perfectly and then the real transformation began.
Her vehicle form was now a sleek but smaller bike. One seat but instead of wheels she had one hover disc at the front and a pair at the back, and she bobbed effortlessly over the ground. Her pink and white colour hadn't changed but now she had dark red striped down each side as well.
"So, I guess you still want me to ride you huh?" Peter laughed and Arcee floated over and bashed him gently in rebuttal. "Want to try it out?"
"Of course, I enjoyed it when you rode me," Arcee replied, and Peter wondered if she got her innuendo or not.
Slipping into the warm and comfortable seat he slid forwards, the bike was designed to be ridden flat, not sat upright and as a port opened where his groin was, he knew perfectly well that Arcee had understood her comment.
