The first touch of the tip of Minimus' digit to the rim of Megatron's main interface port was a shock of sensations to both. Not only was the texture of the metal rough and uneven—the opposite of Minimus' expectation—but it caused the port's owner to tremble so violently that the port bumped into the minibot's finger twice before he took his servo away.
"—S—orry..." Megatron need not apologize for such a beautiful reaction, but Minimus didn't say anything. Megatron's cooling fans were already roaring at their max capacity, they drowned out the sound of Minimus' own booting up.
Perhaps it should've been expected that the array of a bot old like Megatron showed many signs of wear and tear, but only now did Minimus realize that Megatron's array has went through a lot more use than his own; although this should've been expected as well, another huge difference between the two of them.
Megatron and Minimus Ambus had only great similarities and great differences between them, and their current situation had began with one of those differences. When they've met after their most important shifts of the cycle—Minimus unusually without his Magnus Armor—and both have found themselves running a few degrees warmer than normal, it quickly became obvious that their interfacing arrays were not size-compatible. Fortunately for Minimus, his friend was considerably more experienced and had an idea on what they should do.
Minimus brought his servo close again, this time making his touch more firm, Megatron barely managing to twist his neck down enough to keep him in his sight, it added to his image of a struggle. The minibot put his digit-tip on the top of the port's rim and slid it down, this time only one of Megatron's legs spasmed with the shock of charge, and then Minimus caressed a smaller, auxiliary port with his thumb and got a quiet glitch of a voice box in return. That and a warm electromagnetic wave told him Megatron was ready for him to go on.
He pet the well-used ports carefully, mapping out their arrangement and noting down corresponding reactions he got from every type of touch to each element of the array. The atmosphere of the dingy storage closet hazed him enough that he even thought of licking it for a click. He did not need an electrically burned glossa this cycle, thank you very much.
When he had already gathered all the available data on the external, he could proceed accordingly with Megatron's request. He planted his index digit on the rim of the main port again, but this time slid it inside.
The internal layer of metal was tender, smoother than it's edge, less worn down. Its texture made Minimus feel that he was touching something truly intimate now. When he looked up at Megatron his bigger partner wasn't watching him anymore. He could only see the underside of Megatron's chin and the shivers going through the vents on his chest. Minimus caressed the port's walls in circles, speeding up and slowing down seemingly randomly, before just as smoothly taking his digit out.
"Does it really feel that good? I had the impression that nothing should go inside of an interfacing port other than a size-matching cable." he said more to himself than to the hazy co-captain, "I am convinced this act violates multiple protocols of safe interfacing connections, perhaps I should inquire Ratchet about it. I also wonder whether you've thought about doing this before; I would've expected such from Rodimus, but you? I thought of you as of someone who surely wouldn't knowingly endanger anyone's safety for something as petty as pleasure from interfacing."
Then Megatron looked down sharply at him again, this time his optics glowed bright red.
And Minimus held his gaze, and slid two digits into the biggest port.
It's the port's absolute max, only the first segment of the digits slid in without clear resistance and he is not going to risk any damage. Megatron groaned, a sound between pleasure and discomfort, his tactnet is about to be dancing on the thin line between the two for their whole encounter. Minimus silently wishes him luck as he tests how deep will his pinky fit in the auxiliary port.
