What type of person do you prefer picturing in an inflation scenario?

My preference in inflation is more cartoonish and less overtly sexual, so I usually fantasize about my girlfriend or someone else I know, or if it's a hypothetical woman, someone who is more or less similar to me.  But (other than girlfriend fantasies) I often find myself fantasizing about situations involving my female coworkers after hours.  I find the idea of witnessing someone you know get inflated or to have someone you know witness you getting inflated incredibly kinky, and I'm not really sure why.  Maybe it's something about it becoming a story for years to come, or maybe the knowledge that this other person could potentially get inflated at any point and vice versa.  

Snobby and entitled?  (More apt for revenge, possibly?)

Shy and quiet?

Outgoing and charismatic?

Overly sexual?

These have all been done to death in inflation stories, but I am still fond of all of them except the snobby/entitled character.  Recently, however, some of my favorite inflated characters don't really comfortably fit into any of those molds.  They all certainly have their uses.

As far as thinking of people I know, in college I shared a couple of classes with this chick who was kinda cute (not a knockout by any means) but occasionally stuffed her bra because it turned her on.  Sometimes she would do it a little bit, while other times she would make her "boobs" ridiculously huge.  She was into a lot of other kinky shit too, or so she said.  Anyway, I used to mentally plug her into some inflation stories as I read them because something about her told me that she would want to be inflated as big as possible.
