Staying in bed later than usual, telling stories at home (5,2)
I believe the answer is:
lying in
'staying in bed later than usual' is the definition.
'telling stories at home' is the wordplay.
'telling stories' becomes 'lying' (I've seen this before).
'at home' becomes 'in' ('in' can be similar in meaning to 'at home').
'lying'+'in'='LYING-IN'
(Other definitions for lying in that I've seen before include "Staying abed - confined in childbirth" , "being lazy" , "confinement" .)
