Leon was reminded by Jake many times how good his tail feels. While it always annoyed him, he was also partially curious how a tail actually did feel. Leon could finally put that curiosity to rest once he used the program. "Boy Jake, I hope your right about this tail thing." Leon said typing in his profile. Leon sat there for a second thinking about what kind of tail he should have.
Leon thought a fox tail should suffice. It's decent length, and would probably be easy enough to hide. A few additional tabs showed up to add more personalization to the change. "Danm. This thing goes into detail." Leon said looking through the tabs that determined, Length, volume, fur color, fur tip color... there was so much to take in. Leon decided to just keep the default settings for now. "Alright. Here goes." Leon said pressing enter.
A few moments in, Leon was getting so impatient, his spine was starting to cramp. "Danm it! If this thing didn't give Jake-" Leon was stopped mid sentence when he felt his lower back jutting. "Oh my god..." Leon quickly ran to the mirror and turned around to lift his shirt up. He saw a bump on the base of his spine that was starting to grow longer. "Holy shit! This is for real!" Leon said as he saw his new tail wiggle, giving the impression of him wagging it. Leon blushed at the thought.
Leon's tail continued to grow another few inches before red hairs started growing from the base. As the fur spread, Leon felt his tail as it continues to grow in length and fur. "My god. He was right." Leon said, stronk g his growing tail. Leon's tail was now about 1 foot 6 inches as the fur started giving more volume to it. His tail was wide enough for him to hold between his arms. His tail swished back and fourth as white hairs started growing from the tip. "So soft... So smooth... feels good..." Leon got on his knees to stroke his tail from behind his back. Once his tail retained a brush like tip, a force of pressure hit Leon, causing his tail to jump to its full length of two feet.
"Hah! Ahh..." Leon felt the last of the growth, feeling his new tail swish on the floor. He stood up and started stroking from the base to the tip with his tongue hanging out. "Oh god. What a rush..." Leon pulled his tail around from his left side and started cuddling it. "I hope Jake plans on sharing this with me." Leon said stroking his tail.
