Bloke digesting books of sexually explicit nature? (6)
I believe the answer is:
erotic
'of sexually explicit nature?' is the definition.
'bloke digesting books' is the wordplay.
'bloke' becomes 'eric'.
'digesting' is an insertion indicator.
'books' becomes 'ot' (Old Testament).
'eric' going around 'ot' is 'EROTIC'.
(Other definitions for erotic that I've seen before include "Titillating" , "Calculated to arouse sexual thoughts" , "Tending to arouse" , "Sensual" , "Intended to arouse" .)
