Jenna felt the changes begin. He bra felt a little tight so she un hooked it. She looked at herself in the mirror and could actually see them increasing in size. They were now a C and still growing, smiled for a second till she realized how tight her pants were. What the hell, they were loose a second ago she thought to herself. but her ass was nice and round giving her an hourglass shape so she thought nothing of it
The transformation would take an hour so she had sometime to figure out what to wear. About 20 minutes later The button on her pants popped right off and shot across the room. Something was wrong. Her belly flopped out and her waist had widened. a couple more minutes went by and Her thighs grew and split the sides of her pants as she lost a few inches of height off her legs. She spied herself in the mirror, what the hell was going on. Her new big breasts, now DD's flattened and rested right on her round protruding belly. The last minutes of the hour were spend gaining weight over the rest of her body. At the end of 45minutes She was completely round, at 5' and at least 300lbs. She had gained a matter of 150lbs in 45mins. and she had 15 minutes left of changes to go.
