Are you asking if we like those things? I'm a fan of cum inflation ^_^

I adore the slime inflation series you have going, but I have my obvious biases uwu

I can only let you use one character of mine. Kiba is the only one.

Slime inflation is the best. There's not a whole lot of it either.

Magic, cum inflation, slime inflation, food stuffing.

If you are asking about only those options listed:

Cum inflation
Magic

If you are asking for more ideas:
Muscle inflation
Mutation ( such as here: http://www.furaffinity.net/view/13863543/ )
Buttock expansion

^^;

How about Vore + magic?

This moment when you swallow wizzard and now wizzard trying to come out in "messy" way?

like
Fill you from inside by air and you cant do anything just grow bigger until BANG!

Muscle inflatio

You dream about huge muscle? Ask random wizzard for liquid....but who know what gonna happend....nobody before test it :3

Cum inflation WR

Filling somebody by huge ammount of cum until a) he/she gonna hold (for exampole) 3000 galloons of cum or/and b) Bang!

Fuel/Gass inflation - Stealing gass is hard work....and its worst if owner of the gass catch you and play with lighter around you

Lab fun - Testing how much you can hold! - For science ofc >:3

Bomb absorbing hero - You are hero who absorbig every explosion what you can see to save people....bad for you if somebody decide to detonate too much bombs around you....or decide to drop nuke :P

Alert crazy idea!!! - Blueberry Bomb YCH

One character is super huge bomb and second character is a bomb special unit who trying to defuse bomb-character....but there is funny thing....while defusing....bomb character product gass what inflate guy who defuse him :v

Cum + Vore
Filled somebody to limits until this person change into huge, living cum donut and give him to Macro character :3

Cum inflation is the best =u=

slime Inflation is cool ^^

cumflation mostly with a nice boom

Pleeeease continue that slime inflation series!! And other things along the lines of "painful, gross expansion without explosion"
