Optimus Prime

I feel that this could go both ways, he's so super used to it and it is no longer a special or intimate thing UNTIL he has you in there, and you're rubbing his interior absentmindedly.

You can hear the fans get to a higher speed but don't think anything of it.

You are still tracing his stitching, the fans blowing in the back and soft music is playing, something from the early 60s. It is a peaceful scene from your perspective, but what you can’t tell is that Optimus is holding back groans, the way your fingers run along his interior makes him want to explode.

I don’t think he would think the same way about someone being in his alt mode after you.

Bumblebee

I think he is another one that is very open to humans hanging out in his alt mode casually, he has been on earth for a lot longer than he was on cybertron so the rules and imposed modesty has not made a mark.

He wouldnt think twice about you sitting in the drivers seat, until you’re in a skirt and he can feel your soft skin, and you’re gripping the gearshift. It is a normal and comfortable spot to land your hand when driving your own car, so why would it be any different? You don’t realize that maybe certain things lead to certain places when in an autobot. His radio starts malfunctioning and buzzing rather than playing music, he couldn’t hide that he was flustered to save his life.

Starscream

Hes absolutely disgusted to have a vile human in his pristine cockpit, but he couldn’t leave you with the autobots

He probably has to fight with you on not touching anything, no buttons or levers, humans are so curious but might not like what being curious leads to with an already upset decepticon. If you settled in and listened to him, he would not mind nearly as much, it is quiet and peaceful. 

Bumblebee

Tries to pass it off and pretend it doesnt bother him, his fans blasting on at full speed would say otherwise

You probably barely brushed his leg or grabbed his hand to get his attention, something small

I think he would put himself in positions that you would need him and therefore touch him or just where you two would brush against each other

Since that first touch he’ll be caught constantly daydreaming about more, you riding on his shoulder, laying together, simple and sweet things

I think eventually you two run into a rhythm where touching is natural in your relationship

He loves when you grab one of his servos with your entire hand <33

Vortex

It was accidental at first, you had reached for something and thought youd given him enough space but you hadnt, ending up with your arm brushing his shoulder

He probably cussed you out and gave a whole speech about personal space

Stayed far from you, making it seem like he doesnt like you, it was quite the opposite 

He could not get the feeling of your soft skin out of his processor, it was driving him crazy

He didnt want to keep thinking of you and your incredibly soft skin

Eventually hed find his way to you and silently beg for more skin to metal touch

He’d still deny it if his buddies brought it up

First Aid

This guy fumbled so much the first time he felt your soft graze

He was patching you up, youd tripped and scraped yourself up pretty badly, he wasnt aware humans were this fragile

Your arm was the worst of it, bleeding and torn skin, he had you stretch it out and from the tension it had begun shaking. Without thinking you just grabbed his arm that had been steadying yours

He short circuited, his fans were blasting and his hand had gotten very warm

He didnt know what to think other than how wonderful it felt to have you touching him

When you left the clinic he just stood there, feeling your phantom touch, the rest of the medics wouldnt stop teasing him

Swerve

You were a regular at his bar, liaison work was mostly a desk job but the field job was hard when you had meetings or had to track down certain bots. He just thought you were always having a bad day, you just wanted to see him all the time

Hed said something funny to you, you just reached out to ground yourself while laughing so hard

He froze, giggling nervously. He didnt really get a lot of action, let alone have a pretty human give him the time of day

He didnt know what to do, just pushed by it and kept making jokes

The harder you laughed the more you squeezed his servo

He could feel his spike pressurizing, begging silently for you to keep your hand on his
