Do wrong hugging mostly embarrassed temptress (5)
I believe the answer is:
siren
'temptress' is the definition.
(I know that temptress can be written as siren)
'do wrong hugging mostly embarrassed' is the wordplay.
'do wrong' becomes 'sin' (to sin is to do wrong or act badly).
'hugging' is an insertion indicator.
'mostly' means to remove the last letter.
'embarrassed' becomes 'red' (someone may blush or go red when embarrassed).
'red' with its final letter removed is 're'.
'sin' going around 're' is 'SIREN'.
(Other definitions for siren that I've seen before include "Loud warning device" , "Loud whistle or kind of witch" , "She tempts" , "Warning signal generator" , "Warning at sea" .)
