…Rob suddenly started hearing a strange hissing sound. Looking down at his bare stomach, he gasped as it began to spontaneously expand, stretching out like rubber. His cheeks puffed out as his belly got bigger, blimping in size.
Rob kicked his feet as gradually they were lifted off the floor. He was filling up with gas! He was inflating - like a human balloon! Floating away!
As he wobbled in mid-air, belly and butt only increased in size. He was getting spherical now, a big bloated human balloon floating there in his living room, lightly touching the ceiling.
Rob began to think that maybe he should do something before he got too big, and began grasping over his distended belly to press his bellybutton again.
