Jumps like Stephen's heart during a wild kiss (5)
I believe the answer is:
skips
'jumps' is the definition.
(skipping is a kind of jumping)
'stephen's heart during a wild kiss' is the wordplay.
'heart' means to look at the middle letters.
'during' means one lot of letters goes inside another.
'a wild' indicates anagramming the letters.
The middle of 'stephen' is 'p'.
'kiss' is an anagram of 'skis'.
'p' going within 'skis' is 'SKIPS'.
'like' is the link.
(Other definitions for skips that I've seen before include "Waste containers" , "Large containers for rubbish" .)
