Wordy story about starting to kiss at four (9)
I believe the answer is:
talkative
'wordy' is the definition.
(I've seen this before)
'story about starting to kiss at four' is the wordplay.
'story' becomes 'tale' (synonyms).
'about' indicates putting letters inside.
'starting to' suggests taking the first letters.
'four' becomes 'IV' (roman numeral).
The first letter of 'kiss' is 'k'.
'k'+'at'+'iv'='kativ'
'tale' going around 'kativ' is 'TALKATIVE'.
(Other definitions for talkative that I've seen before include "Garrulous, loquacious" , "Inclined to speak" , "Voluble" , "Gabby" , "of many words" .)
