She had just remembered she had to feed her pet horse Sam. she went outside and walked over to the barn with the bag of horse feed in her hands. "Sam!" she called "breakfast!" he stood there in his stall waiting to be fed. she opened the stall door and latched it shut. she bent down and poured the horses feed in the bowl. and was just about to open the stall door to leave when she felt a tingle in her butt hole "oh what the?" she looked down in shock to find a hoses pussy where her human one used to be. "oh no!" he knocked her down and put his hooves around her waist "GET OFF OF ME THAT HURTS!" he began to have horse sex with his former master. as he humped her, she could feel a lump forming at the base of her spine. it grew and grew until it tore out of her skirt and hang over her butt. she stared at it in horror as it started to sprout long blonde hairs, the same color as her hair! Sam finally stopped and she now had a long, blonde, and ugly horse's tail hanging down her backside and two sores on her waist. she stood up and tried to move it. it swung from side to side. "aw man, i got a horses tail!" she then heard the bus stop outside.
