Sorceress wants women to tickle (4)
I believe the answer is:
itch
'tickle' is the definition.
(I've seen this before)
'sorceress wants women' is the wordplay.
'sorceress' becomes 'witch' (synonyms).
'wants' is a deletion indicator ('want' can mean 'lack').
'women' becomes 'w' (standard abbreviation).
'witch' with 'w' taken away is 'ITCH'.
'to' is the link.
(Other definitions for itch that I've seen before include "Prickle" , "Prickling" , "Yen" , "Constant desire" , "Contagious skin infection" .)
