Some blushes at explicit stuff (4)
I believe the answer is:
'stuff' is the definition.
(I've seen this in another clue)
'some blushes at explicit' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'SATE' is hidden within 'blushes at explicit'.
(Other definitions for sate that I've seen before include "Malaysian dish" , "replete" , "Make content" , "Satisfy to excess" , "Fill to satisfaction" .)
