Size-shifting is underrated in vore. Imagine a pred gulping down a prey tiny enough to go down easily and be hidden away within their belly with nobody on the outside being able to tell. The pred goes about their day until the prey, out of spite if unwilling or just for kinky fun if willing, shifts to half the pred's size, or even the same size, without warning. The pred is left a panting and moaning mess having to suddenly adjust to their newly enormous belly and the stares of onlookers.
