The first touch brought lightning-quick focus to his interface equipment by his sensor net in a way there hadn't been previously. It caused a priming flex of his valve as well as a surge of charge along his still-recessed spike.

His chuckle at Orion's appreciation turned slightly static when fingers brushed against the edges of his valve and he wanted to thrust up as the static shock from Orion's touch licked along the rim.

And then Orion dropped down. But he didn't just drop down of course, he also... Engine revving, Megatron's next vent was deeper than usual and slightly stuttered as the fans hitched.

"Orion..." He didn't thrust, no, but he did allow himself to tilt his hips up into the smooth metal and static of Orion's faceplate, optics dim.
