"Well, that sounds interesting. Why don't we..." you started to say, but before you finished he fired the raygun at you. You looked down and saw your jeans were now baggy sweatpants and your entire body began to tingle fiercely.
Your belly surged outward, forming swiftly into a big fat gut that hung down over your crotch, pushing up your stained shirt. Your butt then began to fill out larger and larger, starting to reach the edge of the stretchy sweats you were now wearing, your legs and thighs thickening to match.
You felt your pecs become soft and flabby, growing out onto your gut into a pair of man boons that would make some girls jealous.
You turned to the mirror hanging on the wall in the attic and saw your face get pudgy and thicker by the second, cheeks puffing up, chins multiplying, eyes squinting due to the new level of fat. Your lips even plumped up.
You looked down and couldn't see past your belly, but your feet inflated with fat and burst the socks off your feet. You were officially fat.
"What up, Fatass? How you feel?"
"I love it!" you said.
