Time with kinky porn star is ecstasy (9)
I believe the answer is:
transport
'ecstasy' is the definition.
('transport' can be a synonym of 'ecstasy')
'time with kinky porn star' is the wordplay.
'time' becomes 't'.
'with' means one lot of letters go next to another.
'kinky' indicates anagramming the letters.
'porn'+'star'='pornstar'
'pornstar' anagrammed gives 'ransport'.
't'+'ransport'='TRANSPORT'
'is' acts as a link.
(Other definitions for transport that I've seen before include "Move (from place to place)" , "Movement (of goods or people)" , "Convey; enrapture" , "Convey - delight" , "Convict previously shipped" .)
