Can I relate? Abso-fucking-lutely! I constantly find my mind drifting into fantasies thinking about my favorite characters and biggest fictional crushes belching and/or stuffing themselves like absolute pigs 
I constantly find myself diving into numerous kinky fanfic stories looking for stories featuring my fictional loves. I have even RPd and dabbled in writing my own short kink stories to ahem satisfy those gaseous desires. I find written works like fanfics, stories, and RP logs to be the most satisfying content because I am able to visualize each scenario so clearly in my head and imagine the intrigue details of each gassy eruption in my mind.
Much like GustyTraveler, Sairuka, and Lucien I find myself desiring the belching of fictional characters far more than real life people 
When it comes to fictional loves that I can’t stop applying all of my deepest, kinkiest, and gassy desires to it has to be the silver haired half-demon snack that is Inuyasha 
I like to think that he is fully capable of being every bit of the glutton archetype that you usually see most shonen protagonists fall into. I also think that because of his half demonic biology he would be able to to unleash some truly ungodly belches with ease.
