'stomach' is the definition.
(thesaurus)

'sunak briefly embracing musk without touching' is the wordplay.
'sunak briefly' becomes 'rish' (I am not sure about this - if you are sure you should believe this answer much more).
'embracing' is an insertion indicator.
'musk' becomes 'Elon' (Elon Musk).
'without' suggests deleting specific letters.
'touching' becomes 'on'.
'elon' with 'on' taken out is 'el'.
'rish' going around 'el' is 'RELISH'.

Can you help me to learn more?
