Bondage, even S & M, lent touch of audacity in play (11)
I believe the answer is:
enslavement
'bondage' is the definition.
(thesaurus)
'even s m lent touch of audacity in play' is the wordplay.
'touch of' indicates taking the first letters.
'in play' is an anagram indicator.
The initial letter of 'audacity' is 'a'.
'even'+'s'+'m'+'lent'+'a'='evensmlenta'
'evensmlenta' anagrammed gives 'ENSLAVEMENT'.
(Other definitions for enslavement that I've seen before include "Complete subjugation" , "Joseph was sold into it" , "Loss of freedom in captivity" , "Putting into bondage" .)
