Belly still distended after air inflation?

Hi all, I recently switched up my inflation from 4 litre enema's to trying air again for old time's sake, and after doing it (I got very far as the air had to escape through my small intestine into my stomach) I noticed the next day it still felt a bit distended even though I believe I had fully, or mostly fully deflated. Is it because my abdominal muscles have been streched out and lost form temporarily? Does anyone know why this might be?
Thanks in advance.
