I'm trying to think of a god tag name for tentacles that end in a mass of tinier tentacles used for more delicate stimulation, as in
post #571259 post #574281

how about

tentacle_cilia
tentacle_feelers

nested_tentacles
tentacle_i_n_c_e_p_t_i_o_n

tender_tentacles

While we're on the topic, I created a world_of_tentacles tag.

Tentacular?

Joking aside, I've never heard of a name for this kinda thing before, so it may change eventually, but I think tentacle_cilia is a good one

Alright. tentacle_cilia it is~
