Kyle rushed out the door, and ran beside the building, just out of sight. He didn't want the old man - or anyone else for that matter - to see him transform. In his frightened state, Kyle had forgotten that only Jennifer and Beryl would understand or care what was happening to him. The curse would warp reality as soon as his transformation was complete, and everyone would think that he had always been like that.
But those thoughts were little comfort as he began to change. Every transformation he had experienced felt odd, but this one seemed even more different. Previously, his body had shrunk or grown to fit the clothes .... but not his time. The dress still felt tight, and the pressure only seemed to be increasing. He knew that part of the problem was that the dress was too small, but he had expected his body to shrink into it. Instead his body - at least the portion of it confined by the dress - was growing, constricting the tight dress more closely to his body.
Under the dress, his skin itched maddeningly. The dress was pressed so tightly to his skin that couldn't get underneath it to scratch. So, he tried to scratch through the dress, but it was useless. He felt the pressure ease a little in the front of the dress, and saw with some relief that his breasts were actually getting smaller, and receding into his chest. His nipples felt odd - first, like they were shrinking, then he felt nothing at all as if they had just disappeared.
Unlike his chest, the pressure his abdomen was increasing, as his body became even wider, and strained the seams of his dress. His belly felt bloated and swollen, and as he looked down he saw it slowly expanding. The pain in his abdomen was almost unbearable, until he heard a sharp ripping noise as the dress tore along the side at the hemline. He looked down, and was shocked to see how thick and muscular his upper thighs had grown under his dress. He reached down and touched his thigh. It was covered in hard leathery scales, the same texture as the dress.
His chest now became wider, ripping the dress at the neckline in the back. Suddenly he felt a sharp pain slowly radiating down his back. When it reached the base of his spine, just above his ass, he felt a mass erupt from his back. He gripped the side of the building for support, as the mass began to grow at an exponential rate, thickening and lengthening with every breath. After the mass had finished its last growth spurt and reached its final size, it dropped out of the bottom of the dress and onto the ground with a thud. He was not surprised to see that it was an alligator tail.
