Amy walked out of the pat aisle looking for something to clean herself off. But before she could get too far, her legs began to give out. The increased weight of her body and the ordeal she just went through had taken their toll and she was beat. She stopped by some armchairs in the middle of the aisle that offered free massages. She sat down unable to continue on. Her back breasts felt cramped against the back of the chair and she decided that any back massage would just make her more uncomfortable. Any face of head massage would would also be wasted because it would probably have a hard time working on her muzzle and her wet nose would probably just get the machine nasty anyways. Since she didn't want a free massage to go to waste, she decided to go for just a foot and leg massage.
She leaned back, bearing the pressure on her back breasts for the sake of rest, and pushed the lag and foot massage button. There was also a second row of buttons beneath the first and since none were labeled, she just pushed a random one to get on to the massage.
The chair whirred to life as a pair of rubber mechanical hands popped out from the bottom of the chair. They took her feet and began massaging them gently. Amy had never felt a massage feel so good in her entire life. Her feet were so sore and the hands were working the knots right out of them. She closed her eyes and leaned back drinking in the relief. The hands moved to her ankle and calf, working the sore muscles. Her foot began feeling a bit odd, but the relief was enough to keep her eyes closed.
What she didn't see was the hands actually begin reshaping her foot. They pulled her feet out away from her body, making the foot longer. They added mass to the calf making it stronger. They then covered her toes and compressed them into a single black digit. They moved up her legs, making the udders at her knees disappear and shortening her calf, making it bend further back under her thigh. They moved up her legs adding muscle mass until they reached her exposed groin, where they moved back downward adding a light dusting of brown fur, with a clump of hair over the hoof at the bottom. After repeating the process on her other leg the hands collapsed back into the chair leaving Amy feeling very refreshed.
Amy opened her eyes and tried to push back up onto her rejuvenated legs. Instead, she found herself stumbling over a new set of legs! She fell down onto her still pink bum unable to get her balance. Amy stared a the set of feet in front of her eyes. The massage had turned her once long sexy legs into ugly horse legs! Using a nearby aisle to brace herself, she managed to get up onto her hooves. She slowly began to walk, learning how to operate her new legs. She had to concentrate on trying to walk on what would have been her toes, instead of her whole foot. With some practice, she was finally able to shakily clop around without support. At least her new legs were stronger and the weight of her new udders was not a problem anymore. Holding her arms out for balance, Amy slowly made her way away from the chairs still in search of somewhere to clean up.
