Adam wasn't always a horse....yeah, shocking I know.
Anyways his story goes kind of like this...
He was a normal human, a young twenty year old man who owned a small apartment in the city. He had a great job, a nice family, and a good sum from working.
One day he went to his cousins farm and decided he could help out cleaning the horses for their beauty contest. And as he was cleaning one horse named Luna, a gray furred mare with a black mane and tail, she turned around and accidentally sat on him! Sticking him up right into her uterus. Luna didn't know what this pleasure was, but she loved it, she neighed and sat down more, feeling Adam go in there deeper and deeper, until he was all the way to her womb, he curled up and she expelled his clothes, dripping wet with horse cum.
A stallion came over, and sniffed her dripping funny, and decided he was in the mood. So he mounted the mare and proceeded to hump her. As the two mated, Adam would feel the stallions seeds spurt all over him and soak into his skin, he felt something attach to his belly and soon drifted off to sleep. When everyone looked all over and had the police help too....they declared Adam missing and they stopped the search.
Meanwhile, Adam was undergoing a marvelous transformation, he would become a humanoid horse, or anthropomorphic if you would say, his body changed and he grew gray fur all over his body. He developed a mane and tail, both being dyed blue in some places for un known reason, and his hooves would be blue too, he grew strong inside his mother, and developed a bigger cock. Almost two feet long and under it would be a blue line, it shrunk into its sheath and when it was time....Luna gave birth to Adam, and his last name was changed to Stallion.
Adam can speak with both humans and horses, so he's very helpful in speech. When he ran away, he fell into a portal at a pool, landing him in the nexus, where he found many of his kind here. So he regained another apartment, a new job, and he has a bountiful sum to support him and a family. But one thing remains, he needs a family.... And he wants one. But seeing he can't find enough mares around, he will have to keep looking.
