Sorry, just noticed you said pencil, not pen. I've seen it done in period films where a person licks the tip of a quill maybe to clean off any dry ink. In order to leave a clear mark on paper it was necessary to actually moisten the tip of the pencil filament with your saliva, the resulting product behaved and flowed like ink. Or maybe the ball rotates from the lick to get fresh ink. This subreddit is for asking for objective explanations.
