"We will!" The twins shouted in unison and hugged Mike's forelegs with enthusiasm that made the centaur grin. "Looks like I have some new friends." He chuckled and tousled the two boys' hair. The boys beamed up at him, and then turned to the father. "Pa! You said we could raise a drafter of our own. Can we have him?"
Liam laughed and came over. "Those two eager lads are Joshua and Nicholas. They are anxious to start training a horse of their own. I have to give them credit for good taste." He patted Mike's side. "Of course, you'd have to be a foal instead of a stallion."
Joshua beamed. "Nightmare would fix him for us! She loves being a mamma!"
The older boy came over with an amused look. "Oh, right. Didn't the two of you get into enough trouble over Dale Parsons?"
Nicholas pouted. "He was just mad because he ended up a filly! Anyway, after the first stallion he didn't have any more complaints, did he?"
"Let's not have any talk about unwilling fillies!" Liam raised a warning finger. "If either of you has even the slightest idea of turning this magnificent stallion into a girl horse, I'll geld you right now."
"Oh, no sir!" The immediate reaction of both boys was almost comical - they seemed pretty convinced that Liam was serious. Maybe he was. Mike watched the exchange with a mix of curiosity and apprehension. They were talking about him almost as if he weren't there, or as if he was a full horse.
"Can we take him to Nightmare? She'll like him a lot!" Joshua pleaded with his older brother.
Caleb snorted "She's more likely to want him as a mate than a foal."
Liam grinned at Mike. "Well, you have already experienced the attentions of one needy Shire mare. Want to check out another?"
The prospect of mounting another mare made Mike forget his misgivings and concerns. He extended his hands to the twins. "Take me to Nightmare!"
The delighted boys tugged him towards the pasture. As soon as they were out of earshot, Caleb chuckled. "Guess we better go tell Pa you just sold a horse."
Liam raised a hand in protest. "Hey, I just brought him over for a look!"
Caleb snorted as he started back to the barn. "Right. Already primed and partly transformed, and then turned over to my brothers for a 'tour'?"
The stable hand chuckled and walked back with Caleb. "Can I help it if I know my customers? Both the two and four legged ones."

Meanwhile, Mike was getting excited over meeting another willing mare, his interest getting amplified by constant attention to his privates from the two boys. If Joshua wasn't stroking his ballsack, Nicholas was rubbing the vast black sheath between Mike's hind legs. Either the boys were making use of some residual magic left over from Liam's efforts or they had some abilities of their own. Before they even got close to the pasture, Mike was fully erect with pressure throbbing in his testicles. His interest only got more intense when he saw the mare in question. Nightmare was the most beautiful horse he had ever seen, a massive black Shire mare with glossy black coloring. She snuffled the air as they approached, prancing in a tight circle, her tail flagged.
"Just a second!" Joshua stopped, tugging at Mike's hand. The centaur was anxious and was having trouble restraining himself, but managed to wait. Nichola ran over to the pasture fence and said "We want him to raise as a foal! Please, Nightmare! He'll be a beautiful colt, and that would make him just right for us to train."
The mare snorted, looking at Mike with oddly intelligent eyes. Joshua added "We'll bring you another boy from the village! You can have the whole thing! This one is already partly changed."
The mare stared at Mike another moment, then dipped her head in what looked like agreement. The centaur was having trouble thinking of anything but his own sexual needs by now, though he was confused. Then the boys resumed guiding him towards the pasture gate, which was opened to allow him entrance. He bolted past them into the pasture and circled to approach the mare.
