oh, worm?

His joy and whimsy at seeing this

His acknowledgement of it not being as interesting as the chase

it's an interfacing organ all warframes share, used to tap into technology, possibly including each other. is this sex? you decide.

a warframe's wrist can probably be stimulated in such a way that the blade comes out, like pressing a cat's paws to reveal their claws.

yes, the biometal is packed full of exposed nerve endings. have fun.

HOWEVER, it's also so sensitive that certain types of stimulation walk a fine line between "sexy" and "being violently electrocuted."

the metal may be tough, but parazon injuries hurt like a motherfucker. because of its requirement for sensitivity to work, that might be one of the few sources of pain that can drop an unprepared warframe.

it's built for piercing actions, like ramming into an electronics port, and that might be what it responds to best, but the length of the blade itself can also very much be stimulated.

the string attached is less sensitive and mostly structural.
