The boys were searching for dessert as they wandered through the aisles. As they turned the corner to Aisle 17, Peter saw something. "I know what I want for dessert!" he said, and he quickly waddled down the aisle towards the collection of various brands of chocolate syrups. Aaron followed behind him. Peter's eye was set on the enormous bottles sitting on the bottom shelve. Peter eagerly bent down to grab a bottle, and he hear a loud rip from behind him. The younger's boys cheeks turned bright red as he froze.
Aaron couldn't help but laugh. He knew Peter's pants were fitting him more snuggly than usual. But now his rump had torn a six inch long hole right through the back of pants, exposing white briefs that were looking quite strained as well.
"S-stop laughing, Aaron!" whined Peter. The red-haired boy tried looking over his shoulder to survey the damage. But he could not make out anything in the dim light of the grocery store. "W-what happened?"
"Your big butt ripped your pants!" said Aaron, whipping a tear from his eye.
"No! And my butt isn't big!" Peter did not say that with certainty. There were no scales in the store, and the only mirrors he found were in the public bathrooms. These were mounted above the sink and could not give him a view of his rapidly swelling backside. He desperately tried looking over his shoulder again. "Ugh! I can't see anything!"
"Here. Let me show..." Aaron stepped up behind Peter and placed a hand on each bloated buttcheek. The younger boy's cheeks burned bright red. This was partially because of his friend suddenly touching his butt, but it was mostly from realizing how wide his rear had gotten.
"But...uh...how..." stammered Peter.
"Come on, let's get those off. They're toast, anyways." With Aaron's help, Peter shimmed the destroyed pants off his chunky butt and thick thighs. The older boy help up the pants, examining the massive tear. "Yep. These are goners. But at least you brought other pants with you, right?"
"Uh, yeah. But they're all the same size..." Peter said sheepishly.
"Uh-oh...Maybe it's time to, you know, cut back?" The tubby boy looked crestfallen, but Aaron saw how tight his shirts had become and how the briefs he wore now were a few meals away from the same fate as his pants.
"No! Besides, you're not so skinny anymore, anyways!" That was true. Aaron's once flat stomach had ballooned out into a considerable gut (though still smaller than Peter's) and the blonde knew his jeans were feeling small these days.
"And maybe I should cut back too! Otherwise we'll be too big for all the clothes we brought with us!"
Peter's eyes started to water. "Then why bother staying here? I thought the point of running away here was to stuff ourselves silly all the time! I don't want t-" Aaron, seeing how upset his friend was getting, embraced him in a tight hug. Their swollen bellies squished against each other, and soon Peter calmed down.
"I...I think you're right, Peter," Aaron said, grabbing a jug of chocolate sauce for him and his friend. "Let's take these back to our room."
Peter smiled and led the way, his butt and thighs wobbling as he waddled.
