This is pretty off topic but the cartoon reminded me of "The Kobold Wizard's Dildo of Enlightenment +2." It is an incredibly stupid story about a D&D campaign run by 14 year old sex-crazed male DM who really has no idea how sex works or what women are like. The elf in the cartoon could be one his NPCs.

>Deeming the Whore’s Head Inn no longer safe to hide in, the gang decide to take a more proactive role in their pursuit to get back to reality, or at least to keep Mordred from doing so.
I admit, I haven't read this but it sounds like a Carlton Mellick knockoff
Yep. Stories have been done where the protags are aware they're in a work of fiction, and some of them have the protags grapple with the knowledge that they themselves are fictional characters.
And I'm about to make myself look bad because the example I can think of that most closely matches the bill is the spectacularly trashy The Kobold Wizard's Dildo of Enlightenment +2 (An Adventure for 3-6 Players, Levels 2-5) by Carlton Mellick III :)
Cool, I was gonna say Thuranin are like Kobolds lol
Here is a good book on Kobolds
The Kobold Wizard's Dildo of Enlightenment +2 (an Adventure for 3-6 Players, Levels 2-5) by Carlton Mellick III
This DM's name wouldn't happen to be Carlton Mellick III, would it?
