Once, a friend invited me and a friend of hers over for lunch.
She had homemade burritos, and we could customize them to our liking.
After lunch, my friend didn't finish hers and offered it to her friend, who, being "the chubby friend" (she weighed 213 pounds), happily ate it. (It's worth mentioning that the burritos were very filling.)
Afterward, we went to the living room to watch TV.
And her friend came in, looking very bloated and complaining of pain, saying, "Oh, I'm stuffed, my stomach won't stop rumbling!"
And it was obvious how full she was because her shirt and pants looked tighter than when we arrived, as if she'd gained weight right there. As time went on, she clearly started to get gassy, since her shirt looked smaller and smaller and her belly began to stick out. I was delighted with the sight, and as if things couldn't get any better, she said, "Excuse me, but I need to unbutton my pants." She sucked in her stomach, undid the button, lowered the zipper, and freed her enormous belly. And to top it all off, there was a sound like fabric tearing, to which she said, startled, "I think my panties ripped." But then she didn't make a big deal of it. The rest of the day she didn't button her pants, so I could see her light blue panties and her round belly bouncing around every moment.
