Houndoomtaur

Hailey was walking home from a Halloween party. Her long blonde hair floated in the nighttime breeze as her blue eyes focused ahead to her destination. She zippered up her wind breaker and shivered, as she was stupidly wearing ripped jeans. She continued walking when she decided to take a shortcut through the graveyard. She was about to walk under a branch of an oak when something that was not hanging from the bough before hit her in the face. She rubbed her head and discovered a silver chain necklace dangling from the branch. She plucked it from the leafless tree and found a pendant of Houndoom carved out of a piece of silver. She looked around, making sure there was nobody in sight, and quickly put it on. She did not want to look like a grave robber. The graveyard trail turned into a nature bicycle path, which puzzled the girl. She leaned up against a tree to take a break when she was engulfed by continuous surges of pleasure. She fell to the ground as her body began to transform.
Hailey rolled around on the ground as her feet shredded her sneakers and transformed into dog paws, complete with white claws on each of her four toes. Her ankles became covered with three connected rings of white, bone-like material as her feet softened and became pitch black. Her knees snapped backward, causing the girl to wince momentarily as the coloring crawled up her leg. Her pleasure increased as a six foot long demon tail grew out of her butt, tearing apart her jeans. Her spine elongated as two more legs grew out of her hips and grew to the exact shape and size as her original ones. The coloring changed on her undercarriage, turning orange as three bone-like protrusions came out of the top of her bottom half. Her chest turned orange, while the rest of her body turned black as her hips exploded out and her belly was sucked in. A white skull formed in the middle of her two breasts as they shredded her windbreaker and undershirt and expanded to a G cup. Two more bone-like structures came out of her shoulders as her wrist gained similar rings as her ankles. Her hands turned four-fingered, and each fingertip had a rough pad as well as on the palms as each finger was topped with a white claw. Her neck lengthened slightly as the front of it was colored orange, while the rest was colored pitch black. Her face stretched into a dog muzzle as her teeth became razor sharp and her nose turned black. Her face was colored orange, while the rest of her head was colored black as her irises turned red. Two large curved horns grew out of her head as her hair darkened to black and grew down, going past her body seven feet. Her hair became curly as orange highlights entered the hair and the changes ended.
Hailey rolled around for several minutes, still engulfed in great pleasure. The feeling eventually left her, leaving the girl feeling strangely empowered. She dusted herself off only to see her body had changed. She looked at herself to discover that she was now a tauric Houndoom. She smiled, knowing that she was now her favorite childhood Pokémon. She decided to run away into the trees and disappear forever. She sprinted into the forest with incredible speed and agility, swerving in between trees and jumping over large ponds. She eventually came to one of those small ponds and decided to rest. She was about to take a drink of water when she was enveloped by pleasure once more. Her breasts doubled in size as her hair doubled in length, and she began to grow uncontrollably, eventually towering over the trees that she saw in every direction.
The girl shook off the pleasure and discovered that she was now gigantic. She hugged herself and vanished into the woods, never to be heard from again.
