Still panicked from his sudden change into a horse, Max was then approached by Rosa and Leya. "What happened to me? Why did you
turn me into a horse?" Asked Max. " I felt it in your heart that you were a good child and that you would make a great member to our
family" said Rosa. " But don't worry, the change is not yet permanent, you will change back soon". Said Leya. " however every time you
become stressed out, you will turn back into a horse". Said Rosa. " if you wish you can make the change permanent. All you must do is
release your seed into a mare." Max blushed, he always thought that having sex with a horse was something vile. " when ever you penis
becomes erect wether you are a boy or horse, it will turn into a horse penis." Said Rosa. " we have talked to our mates and have agreed
that if you do choose to become a horse forever we will allow you to mate with ether me or Rosa". Said Leya. Until you find your own mate
which could be ether Horse or human". "Be warned though, if you impregnate a human female she to will change into a horse forever."
Said Rosa. Max's body then began to shrink as he started to change back into a ten year old boy, when the changes finished he laid there
naked before getting up and running home as fast as he could. Over the next few weeks, Max changed back and forth from human to
horse due to teasing at school or a test that was the next day. One night he laid in bed thinking about how bad his life was as a human. He
then decided that it was time for him to make his choice. He got up from his bed and opened his window and climbed out, his bare feet
touched the grass. He then ran as fast as he could to the stables. When he got here he saw Leya there. He walked up to the beautiful
mare and petted her. Leya could see it in his eyes that he had made his choice. Max felt his Penis grow into a gigantic horse penis as it
ripped through his pants. He took off all other clothing and he was now completely naked. He got upon a stool that was behind Leya and
presses his large horse cock up against Leya's vagina. He then pushed his cocke inside of the mare and began pumping away. As he
continued his muscles in his body tensed again and the process of his change began. He could feel his legs growing visibly more
powerful. Max moaned as his hands and feet lost their human shape, and turned into hooveed legs. He continued to pump inside Leya as
his cock grew larger inside her. The juices from her horse pussy were turning him into an adult. His hair grew into a majestic looking mane
while his human teeth fell out of his gums and got replaced by his bulky horse ones. His intestins changed, growing to fit his big frame,
and his sperm lost its human DNA and was replaced with horse sperm. His neck stretched out as brown fur covered his whole body, his
chest barraled out one last time as he whinnied softly with his changing voice as he continued to pump his cock into Leya which he was
now as big as. Max closed his now big eyes as they moved to the sides of his head, his face stretching out to form his horse muzzle and
his now pointy ears moving to he top of his head. His changes nearing complete, Max felt what he had been waiting for as his balls
tightens, he pumped inside of Leya one last time before releasing his seed into her. Both horses whinnied proudly as Max's fate as a now
adult horse was sealed. Max climbed down off of Lela now glad to be apart of this family. Just then the barn door began to open.
