Where desires are titillated by top-shelf bust (8)
I believe the answer is:
fleshpot
'where desires are titillated' is the definition.
(place providing sexual entertainments)
'by top-shelf bust' is the wordplay.
'by' is a charade indicator (letters next to each other).
'bust' indicates an anagram.
'top' after 'shelf' is 'shelftop'.
'shelftop' is an anagram of 'FLESHPOT'.
(Other definitions for fleshpot that I've seen before include "Place for hedonism" , "Venue providing lewd entertainment" , "place for titillating entertainment" , "strip club?" .)
