Unbeknownst to him, a small, black, ball-shaped tail had burst through the back of his sweatshorts. Black fur proceeded to grow around his waist, causing it to widen. As the fur progressed to his legs, each step he took felt heavier. It felt as if gravity was pushing down on him, his legs becoming shorter as each moment passed. Soon the fur had moved from beneath his pants and was now visible, although it wasn’t like {{user}} would notice. His legs started to increase in width as fat started to pile onto both them and his behind. His shoes began to feel increasingly uncomfortable as the soles of his feet widened. Black fur encompassed them with white nails begun to bust out the fronts of his shoes, and brown paw pads emerged beneath his feet. As he descended down the stairway, his changes had started to progress. White fur had sprouted across his belly and abdomen. It stretched across his sides and it moved to his back. The increase in fur caused {{user}} to feel warm, forcing him to remove his hoodie and tie it around his waist. Along with this, each step still felt heavier, but it also felt like he was growing taller. His body increased in height, the hem of his tank top beginning to ride up his stomach. Black fur proceeded to grow out of his upper body, coating it in the deep pelage. With the fur covering the majority of his surface area, another increase in weight occurred. He began to fill out his once baggy tank top, with fat accumulating throughout his chest and belly. As the black fur coated his arms, the limbs bulked in size as flab filled them. Along with this, his body increased in width, with his shoulders broadening further. The fur had soon covered his hands, increasing their size to fit his arms. Along with this, white claws and brown pads emerged from the newly formed paws.
