Jen stood there holding her breath for a minute. Suddenly she felt a great heat shoot all through her body. She watched in shock as her breasts, once an ample bust, inflated, swelling to their new massive size, they looked ridiculous on her petite frame. Her breasts rested proudly on her body, still perky and full, they looked as if she were arching her back just to show them off, and she was still standing up straight.
The heat grew more intense as she felt her body swell, her arms thickening until they were nearly twice their size. Her abs grew more defined, giving her a six pack Brad would have died for, her legs grew more defined, much more than her boyfriend's. Her chest pressed outward, as the muscle on her back grew more defined, her neck was the last to thicken. She gasped, there standing in the mirror was a chiseled, sexy amazon, she now weighed 190lbs. She saw her bust raising and lowering with every breath, she tried to wrap her mind around the fact that her breasts were now several time larger than they were, and she had gained fifty pounds of muscle in a mere matter of seconds.
"I... I think I can live with this." Jen stammered to herself, she felt her body lurch slightly, her muscles grew denser, though she couldn't notice it, she couldn't even think at all right now. And what was worse, all this growing had made her horny, and the bus had just pulled up.
