Atoll where one pursues lovingly flexible relations (6)
I believe the answer is:
bikini
'atoll' is the definition.
(I've seen this before)
'one pursues lovingly flexible relations' is the wordplay.
'one' becomes 'i' (Roman numeral).
'pursues' is a charade indicator (letters next to each other).
'lovingly flexible' becomes 'bi' (I can't explain this - if you can you should believe this answer much more).
'relations' becomes 'kin' (I've seen this before).
'bi'+'kin'='bikin'
'i' after 'bikin' is 'BIKINI'.
'where' acts as a link.
Can you help me to learn more?
(Other definitions for bikini that I've seen before include "Small two-piece bathing suit" , "revealing clothing" , "Skimpy beachwear" , "offering scanty cover" , "Skimpy two-piece swim wear" .)
