"Since you're so satisfied," Derek said quietly as Sonya continued her nap. "Let's go a little further. First your feet and hands will become like tiger paws."
Derek continued petting Sonya as he watched her fingers thicken and shorten into the unmistakable paws of a feline. Her thumbs shrank to almost nothing and moved up her arms, while her legs adopted a proper digitigrade stance. He watched her tail swishing around on the bed. "For a little fun, how about making that tail a little longer? How about ten feet."
As her tail grew out from her back, Derek asked her quietly, "How about we make you into a full tigress? You will first loss your human voice, only I'll be able understand you so that you don't accentually kill me when we have an argument, next you will gain an extra foot to each lag, next you will gain a few pounds, lastly you will gain a cute little pink heart shaped collar that will say "Sonya & Derek together forever!"
He decided to wait a few more minutes before waking her. She looked so cute and peaceful, and he had never had such a creature on his lap before. Derek was savoring every delicious moment.
When the time came to wake Sonya, her lags had grown almost a foot, and was no longer human. And under the Transformation Collar, a cute little pink heart shaped collar that said "Sonya & Derek together forever!"
His legs had started to fall asleep. Derek gently prodded Sonya to get up. She grumbled at first, but after a few soothing calls of "Sonya," her ears perked up and her eyes batted open.
