Sean, thus deployed, traps Black and Tans (9)

'tans' is the definition.
The answer and definition can be both related to bodily activities as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?

'sean thus deployed traps black' is the wordplay.
'deployed' indicates anagramming the letters.
'traps' is an insertion indicator.
'black' becomes 'b' (as in pencil classifications).
'sean'+'thus'='seanthus'
'seanthus' with letters rearranged gives 'sunathes'.
'sunathes' enclosing 'b' is 'SUNBATHES'.

'and' acts as a link.
