"Lets go with...um...well, how about 250 Pounds of fat?" you say.
"Well, that sounds very resonable. Very wise. You could have been much fatter, but taking your time will be a good thing. allow your body to get used to changing in that way. Okay, boy, time to get your tubby on, you ready?"
"Ready as I will ever be, sir!" you shout, excited about the change to come.

You start to inflate with fat, a feeling so wonderful you can barely contain your elation. It feels like you are going to exlpode with pleasure, let alone chubby fat. Your clothing is now much tighter, but it hasn't torn yet. Your t-shirt is lifing as your new pot belly pokes out, going from beer-gut to bear-gut in a matter of seconds, as your ass begins to get real chunky. Your face fills out slightly, and then more so as you gain a second chin, and you feel your cheeks puff out. You look at your hands as the fat fills them, making them thick and juicy, like, well, you know. Your feet, which are encased in your shoes are making said footwear very tight, as the gain comes to a slow, your clothing begins to slowly tear at the seams, but it doesn't burst.
