Lascivious Tory mug, I sense (12)

Ross

I believe the answer is:

concupiscent

I'm a little stuck... Click here to teach me more about this clue!

'lascivious' is the definition.
(thesaurus)

'tory mug i sense' is the wordplay.
'tory' becomes 'con' (abbreviation for Conservative).
'mug' becomes 'cup'.
'sense' becomes 'scent' (I can't explain this - if you can you should give a lot more credence to this answer).
'con'+'cup'+'i'+'scent'='CONCUPISCENT'

Can you help me to learn more?

(Another definition for concupiscent that I've seen is " lustful".)

I've seen this clue in The Guardian.
