Kiss skin (5)
I believe the answer is:
graze
This clue is a double definition.
'kiss' is the first definition.
(I've seen this before)
'skin' is the second definition.
(thesaurus)
(Other definitions for graze that I've seen before include "Eat grass, or snack" , "Eat grass in a field" , "as some animals do" , "Scrape - feed on grass" , "Eat lightly and often" .)
