Getting fatter is fun, but what if we sped the process up, and inflated me into a much MUCH bigger version of myself!
Stuffing with food can be slow, but what about with water? Making me your waterbed that you can move around on as I jiggle. Or what about with air? Inflating me with a bike pump, making my clothes burst off my body.
Each pump pushing me closer and closer to ecstasy, until I can't take it anymore, and finally I climax right as I *POP*!
