While terrifying, the strange tingle and tickle of fur spreading across your skin isn't more or less uncomfortable... Heck, despite himself, Burt began to slowly grow used to the spread of tan pelt across his arms and legs. However, as the fur spread around his waist, a strange sensation began to bubble around the small of his back. And with a sudden jolt, something began to press and bulge, slamming against the fur covered flesh of his lower back. Suddenly that spasm quelled a bump, then a bulge, then a protrusion, as something slowly began to swell and form above his rear. Trying to hold it back momentarily, the swelling began to slide from the confines of what fabric he had left, slipping from the waistbands, and sprouting out for the entire world to see. He could only freeze, as the new appendage grew from a simple bulge, to a major limb growing to the size and girth of his legs, as it weighed down on his lower back. Now his odd changes couldn't be hidden. His wallaby side was out for everyone to see now.
