Watching cunnilingus from a female perspective.

<CLOTHED|NUDE> VIEWER

Is the main perspective character wearing clothes?

Note that even if wearing clothes, the pussy will be exposed.

Deciding whether the person doing the cunnilingus is clothed.

LONG TONGUE

Sometimes the character's tongue is abnormally long, not the length a human can have, please use this tag as a suppression.

Maybe your character is a lizard man, and does have a super long tongue, in this case it can also be used as a positive tag.
