Fulfilment (8)
(Another definition for fruition that I've seen is " Realisation, fulfilment".)
'fulfilment' is the definition.
(satisfaction is a kind of fulfilment)
This is all the clue.
(Other definitions for satisfaction that I've seen before include "Pleasure" , "Gratification" , "I can't get no - (Rolling Stones)" , "Fulfilment; compensation" , "Contentment; reparation" .)
