Rampage could feel people's sparks all the time, but for most mechs, that was only achievable during intimate acts like this. The rush hits him hard, and First Aid arches and gasps as his spark flares from the surge of energy and brush of emotions against his. He feels Rampage's need, and the hot clench of Sixshot's body, and he's shaking when he's finished hooking them up.

"Oh, Primus." It's not even the same as pressing their chests together, but Rampage has an overwhelming spark.

It was hard to hear Sixshot over the thrum of Rampage's spark radiating through his whole frame; he feels drunk and unsteady, almost floating, and as he turns back to face the six changer he's clumsy, tripping over his own hands.

"I've got you," he whispers, his vocalizer slurring the words slightly as he takes Sixshot's cord back in hand.

He knows that Sixshot will probably overload as soon as he's in him -- maybe not even fully in -- and he's tempted to stroke the six changer to completion instead and feel the hot spurt of fluid and pulse of his knot in his hands. He'd probably like that very much. It's the pulse of need in his own frame that decides for him though; he aches to be filled, his valve clenching down on nothing at the moment.

First Aid shifts, pressing the thick head against his opening, stretching the rim almost to the point of pain before it pops past it, and he stills suddenly at the sudden pressure against his interior nodes. He doesn't linger for long, trying not to tease the six changer, and he drops his weight, sinking down to take the spike further in, his calipers clenching and squeezing to help ease it deeper until he was completely seated.
