Currently in-game if your breasts are "inflated" by the dolls and so on, this magically becomes breast flesh. This will no longer be the case if you choose to enable the new inflation and weight gain fetish. Your breasts will literally inflate with gas like balloons, and this gas is lighter than air, helium style. Your breasts can actually become weightless or lighter than air from this. Your breasts will slowly deflate over time.
Your belly can also be inflated with this air. Currently this air exits along with cum and everything else the traditional way, but I'm looking for ways to balance deflation further.
Having enough air in you makes you weigh less than usual, which means you fatigue slower. But if you're too light, or even weightless, you won't be able to get much force behind your attacks.
Becoming lighter than air is possible. If this happens then you will uncontrollably float in the room you're in until you deflate, which may mean there are several monsters waiting for you when you land. Many NPCs will taunt and humiliate you whilst you're stuck floating. In the woods, you'll float way up high and probably land in a different room.
In summary inflation, if managed properly, could help mitigate the wait of your body. But too much inflation is definitely a bad thing. I have plans to expand inflation to your ass but I'm still figuring out the details.
Weight gain, on the other hand, is also possible with this fetish enabled. Essentially if you rest on furniture too often, expect to start getting wobbly arms, thighs and butts. One of the kneeling stools in the dungeon will be cursed, adding a lot of fat.
Exercise is not walled behind the fetish but is relevant. Essentially, performing exhausting activities like attacking and jumping off dildos increases a hidden counter. If this gets high enough without you having needed to rest on furniture, you gain a point of dexterity or strength. Killing a monster massively increases your exercise count. If you have any fat on your body from the above fetish, you'll have to burn that off before you can gain any stats. Burning off fat takes less exercise than gaining a stat point.
The code and descriptions will make a distinction between hip width and ass size when this fetish is enabled.
