From the wiki page of spitroast
"A sex position where a character is orally and anally/vaginally penetrated at the same time."
From the wiki page of double_penetration
"A character who is being penetrated by a combination of 2 routes (oral, vaginal, or anal) all at the same time. This can be from any combination of sex and objects."
If 'spitroast' applies to all means of penetration, not just using a penis or strap-on, then spitroast should imply double_penetration by its very definition. If not, the wiki-page should be updated to specify what must be used by the penetrating partner.
