I used to have a hypnosis fetish, which disappeared very early on, but I think it's left traces in this idea. A while back I mentioned here whether being inflated would make you "high" (mentally rather than physically!). Increasingly now, I'm finding the idea of inflation that makes me somehow mentally out of it, delirious or, well, trippy really arousing. I can remember a comic strip where someone had to swallow a huge pile of spaghetti in one strand and she carried on until she exploded, and the frame before shows her looking kind of flushed and cross-eyed because she's so physically overwhelmed with being stuffed to bursting point with pasta.
I think part of the appeal is that it emphasised the sheer powerfulness of the inflation material. I've written a story which emphasised this aspect of being inflated from the inflatee's perspective but it's really long and handwritten, so it won't be appearing here.
Does anyone else relate?
I think I can get behind this. I've been known to get a little light headed and giggly as I inflate. Of course I usually think of it in terms of getting drunk rather than getting high, but I think the essence of impaired judgement is still the same here.
