Is this from a specific episode or is it fanmade? Reverse image search doesn't sadly find you the source of this picture.
Also in Family guy season 17 episode 19 we can briefly see Meg going to the toilet and taking a dump. It is very simple and obviously non-graphic but maybe someone is interested in that.
Apparently Season 10 of Archer will also get a toilet scene which we can see on the trailer.
