I've come up with some new variations of inflation, which was inspired by none other than this Daffy Duck cartoon.
The first I'll call Pump Inflation, which is where the inflatee's body inflates and deflates rapidly, gradually growing bigger with each inflation.
The second I'll call Random Inflation, in which a part of a person's body, for example the breasts, swell up for a time, then deflate a short while later. But before they can relax, another part, ie the belly inflates. This soon deflates, but then another part inflates, leaving the inflatee guessing which part blows up next..
Sound interesting enough?
Those sound like great concepts! I like the fact that the inflatee knows she'll be blowing up repeatedly, and can't do anything about it. It adds a lot to the tension, wondering exactly what will happen next.
