He'd actually have to slip under armor to get at the root of his tentacles, those are firmly attached to protoform. Not a surprise, considering how the rest of them is unarmored. He isn't shy about making sounds either, and they're all... pretty interesting.

Purring, deep and rumbling, something that was not his engine, and gentle, musical chrrs. He was pretty quick to move the tentacle in his hand too, demanding more of that and faster. As for the other, it was also just as demanding, and curled itself around his hand in a moment.
