Liberal couple with sense accepting offer, yielding to desire? (10)
I believe the answer is:
libidinous
'yielding to desire?' is the definition.
(libido is sexual desire)
'liberal couple with sense' is the wordplay.
'liberal' becomes 'lib'.
'couple with' becomes 'idi' (I can't explain this - if you can you should believe this answer much more).
'sense' becomes 'nous' (nous is a kind of sense).
'lib'+'idi'+'nous'='LIBIDINOUS'
'accepting offer' acts as a link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Another definition for libidinous that I've seen is " lustful".)
