Inflation Fetish
A fetish centered on the idea of a body (or a specific body part, usually the belly) becoming visibly enlarged, swollen, or filled, whether through air, liquid, food, or a fictional means. In erotic fiction it shows up as deliberate belly expansion, body inflation, or a character being 'filled up' until they are round and taut.
Why readers love it
Readers drawn to inflation fixate on the visible evidence of fullness and the helplessness of a body that keeps growing, which pairs naturally with power exchange, embarrassment, or forced indulgence. The appeal is often less about the mechanics than the surrender and loss of control over one's own shape, and the looming threat of how far it can go.

Worth knowing: When inflation play involves real physical expansion or forced feeding in the real world, agreeing on limits and aftercare ahead of time matters because stretching and overfilling can cause genuine internal discomfort or injury.
