...a small pedicure machine. The sign read "Pedicure Master!" There was a money slot for this one, five dollars! Grabbing her fallen purse, Kelly approached the machine and shucked off her oversized shoes and peering at her still human shaped feet. They looked very odd with the blue skin, just not fitting at all. She pulled out a five dollar bill from her wallet, racing to the machine and inserting it, before setting her feet into the empty receptacle of the Pedicure Master. The machine whirred to life almost instantly and a screen suddenly slid up to meet her gaze. On it she saw an image of her feet as they currently were.
"Scanning." The Machine intoned. There was a moment's humm, and a warm light drifted over her feet. "Current status, Demonic transformation, appropriating possible pedicures." The screen brightened a moment and Amy saw several options appear. The first was a pair of cloven hooves, the second like the talons of a bird, the third claws like an animal would have but still somewhat human shaped.
She grinned devilishly and pressed the option for imp talons. The machine whirred again and the screen withdrew, and almost instantly the empty basin began to fill with scalding hot water! Normally she would have screamed in pain but now, the water felt perfectly pleasant on her impish skin. A moment later the water began to bubble and froth and Kelly gasped softly as it felt like hands were moving along the bottoms of her feet and over her toes. It was painful, yes, but in that delightfully pleasurable way that any demon desired. Kelly smiled and relaxed as she sat back, wiggling her toes.
It felt like her feet were stretching, no, molding. IF she could have seen beneath the water she would have seen that the human shape of her feet was quickly distorting. The arch of the foot was rising just slightly, giving her a uniquely digitigrade stance, and the space between the arch and the ball of the foot was shortening. Her heel burned as blue blood leaked out...even as a long spike like a talon grew from the back of it. This spike formed a new unique claw toe that no human possessed. Meanwhile the bottoms of her feet were becoming tougher, stronger, almost scaled like birds feet. Her five toes were beginning to misshape and reshape to three equally sized digits. Long talons grew from each digit as they spread, perfectly molding against the bottom of the machine.
Kelly didn't seem to mind at all as the last remnants of humanity were smoothly stripped away, the machine whirring as the water drained. She smiled and lifted her new feet up, grinning devilishly. New instincts told her that these were stealthy and strong, capable of holding on to even the most smooth of surfaces.
"Now...what's next..."
