"Must be hearing things..." John muttered to himself, as he undid the sash. As he slid off the coat, his stomach gurgled loudly.
"Lunch time it is then." John rubbed his belly, when suddenly he started to feel bloated. He patted it and grimaced.
"Maybe I misinter- buuuuuurp." John was cut off by a large belch. He quickly looked around, then realised he was alone.
"Not too shabby." He smiled and turned to the mirrors.
"What the?" John stared at his reflection. From the neck up he looked completely normal, but it was the rest of his body that left him speechless. His torso looked completely bloated - a fat gut was now attached to him, forcing his t-shirt to ride up and show off the beginning curve of a beer belly. He looked down at himself, but only saw his usual rock hard abs. John looked back at the reflection, still showing his inflated self.
"Hey, that's pretty cool!" John said, as he looked at the bigger 'him'. John turned for a side profile to see that his 48-inch gut stood out proud. He patted it and nodded his head when he noticed that his ass had swollen as well. John smiled at his reflection as an idea came to him. Quickly, he took of his shirt, and found a topless big boy looking back in the mirror.
"Man, they go all out here." He grinned as he began to pose like a body builder. His stomach had lost all definition, and looked taught like a pregnant woman's at nine months with triplets. Love handles however, had developed and were pooching over his straining waistband. His pecs were meaty slabs, no longer cut but firm and round rather that saggy. Like his chest, his arms had grown to resemble a bodybuilder during the off season - large and strong but a layer of fat softening it's appearance.
John forced his gut outwards and found that his reflection mimicked him with greater results. John removed his pants, and kicked them away from his feet. He looked up and saw that his thighs were now pressing against each other, and unlike his upper torso were mostly over stuffed sausages of fat. He stepped them apart and found that they still touched.
"I am one fat fucker." He said as he slapped his belly and watched it bounce slightly. John then turned and saw that his ass cheeks were huge- the size of basket balls, and had partially forced themselves over his boxers showing a large portion of his butt crack.
"Now I know what it's like to be a plumber." John looked around, and after making sure no one was peeking, took of his underwear. His gluteus maximus wobbled with its freedom and john saw how big they really were. No longer confined, his checks were bigger than basketballs, more like over inflated beach balls. He turned around, but found that his dick was only slightly larger.
"Oh well, new it had to end somewhere..." he said, a little disappointed. John's stomach began to gurgle again, and like before, he felt a pressure begin to build in his gut.
