Audibly moaned over sweetheart's raised skirt (8)
I believe the answer is:
sidestep
'skirt' is the definition.
(synonyms)
'audibly moaned over sweetheart's raised' is the wordplay.
'audibly' shows a homophone (sound like).
'moaned' becomes 'sighed' (I've seen this before).
'over' says to put letters next to each other.
'sweetheart's' becomes 'pets' (both are terms of endearment).
'raised' shows that the letters should be reversed in order.
'sighed' is a homophone of 'side'.
'pets' backwards is 'step'.
'side'+'step'='SIDESTEP'
(Other definitions for sidestep that I've seen before include "Find a way round" , "To avoid" , "Shift to right or left" , "Dodge - circumvent" , "Dodge (an issue?)" .)
