Some sexy inflation things
Ephesising how "full" you are, the word "full" im general
Being called fat despite the fact that you're more of a balloon
Being called pregant, which month is it
Air pump somewhere in the backround, disconected from you like it indicates that you're done inflating and that there was the source of that round gut
The word "gut" is also quite sexy
Belly "like a drum"
Being called "huge"
Someone worrying "omg what happened to you‽ you're huge!!!" Ghmnnn
Being shy about inflation
Being confident about inflation
Being casually inflated. Like you blew yourself up and now you're going about your day, doing laundry and shit like that
Being about to burst or explode and complaining about it "ooooh I feel like I'm gonna pop" "A few more pumps an I'll explode aaugh"
Also something about the casualness of inflation - when you inflate for some purpose like to be more buoyant on water
Inflation as a skill when you need to train your belly in order to get big
And classical wardrobe malfunction when buttons pop off of your shirt and pants
And of course when your own belly button pops out because of how full you are
These are just some things I find hot in inflation. I freaking love that kink, it's so weird but so nice
