MissPorker:
You know you're fat when you can feel your belly jiggle against your thighs as you waddle around
ThirteentailsGetsFat:
This is a relatively new feeling to me, and I really love it!
It took me a second to realize what that sensation was but it was very arousing when the full weight of the situation set in (no pun intended). I've gotten so fat that I've graduated from belly hang to full on apron.
