Stuffing

First time getting stuffed/bloated by someone else

I finally came out to my girlfriend about my fetish for stuffing, bloating, and inflating, and she's willing to bloat or stuff me (inflating is still a bit out there for her). This is my first time having anyone else help me or even be present while I do it, so I'm a lil nervous on how I can setup a situation or scenario where she can stuff me with food or liquids until I can't possibly take more. Any tips or ideas, especially from others that have been the stuffer or stuffee?
