The mares around the pool were paying more attention to Derrick now, and their scents were stronger and more attractive. A few were ready for breeding, and he saw the real stallion snuffling one of them in preparation for mating. Although he was attracted to the horses, Derrick felt a twinge of concern over mounting an animal while he was a centaur. It didn't seem quite right.
"This is an amazing form, and I am really happy with it." Said Derrick. "But I was wondering if you would mind turning me all the way into a Shire stallion, just for a while?"
Hephaustus grinned broadly. "Mind? It would be my great pleasure! The only thing more handsome than a black Shire centaur is a true black Shire stallion! And going all the will be an even more unique experience for you. To think and act as a horse, to be a stallion to your very soul is a gift I am happy to give."
"My soul? You would change that too?" Derrick was a little uncertain about that.
"Of course, at least if you really want to go all the way." Hephaustus shrugged. "I can give you just the form, but you would still feel a little awkward mounting the mare. To truly be a horse, you need the soul of a stallion as well. But that is your choice, of course."
