so uh, i'm writing this fic where matt mysteriously grows tentacles and i just....does anyone have advice on how to write tentacles? because i get they're supposed to have a mind of their own and all, but sometimes i feel stuck because idk HOW much of a mind of their own they're supposed to have.

for example, i plan to eventually have matt, er, get friendly with the tentacles but i don't want it to come off rape-y? HELP????
