"I apologize for my comrades but we don't use to use such a good transformation since a while." Tom said while he inspected Nick's mane. "Almost all our clients are old fat men who turns into old horses who can barely move. You, on the other hand, are a fine specimen, a great stallion in my opinion!"
As a horse, Nick can't say a word but he wasn't really pleased of hearing that explanation from Tom. He didn't want to be a horse but he must be one if he wanted to become young again. He shook his head as his only way to communicate with his rider.
"You're well-built, good musculature and strong legs." Tom said while he stared at Nick's big horse butt. "You'll do great in the race!"
Nick was really happy of hearing that. Finally something comforting after all the bad luck he'd got since he arrived to the island. He tried to thank Tom but he neighed instead, he felt so ashamed of that but his horse face can't show his embarrassment.
"It's a shame you aren't a real horse." Tom said while he patted Nick's back. "Our horses are getting old and we don't get good horses for breeding..." Tom stared at Nick's sheath where his horse shaft was hiding. "I know this isn't why you transformed for but I'll be very glad if you give me a little bit of your seed."
Nick freaked out after hearing that. Has Tom asked for his horse semen? That's insane! Disgusting and insane. He had never donated sperm before. Well as a kid, how much sperm he could donate anyway?
Now, thinking about it, at the idea that in the future some foals could be his children made him freak out even more. Those thoughts are too much for a 11 year old!
"I won't force you to do something you don't want but it would mean a lot to me." Tom said while he put the saddle on Nick's back.
Nick thought about it for a while, Tom has been good with him since they meet and if he's depressed he couldn't do as well in the race...
While Tom attached the girths around Nick's belly he noticed that the horse was slowly unfolding his shaft from his roomy sheath until the long pole was hanging low in all it's glory.
"Are you trying to tell me that you agree with my request?" Tom asked and Nick shook his head in approval. "May I?" Tom grabbed the pole in his hands giving Nick a slightly unpleasant tingling that almost made him regret of his choice. "Wow, it's gorgeous, 32 inches, good skin texture and girth. I almost don't believe you didn't born as a horse!"
Nick neighed as a sign of displeasure and made a few steps away from Tom.
"Sorry, I'm sorry. I didn't want to upset you. It's just that I'm really impressed." Tom walked to see Nick face to face. "I know you didn't choose any of this but you should be proud of how gorgeous you have become." Tom took his phone and showed it to Nick. "Look, this video explains how a man's body changes after eating a candy. The transformation don't rewrites your DNA so even if you have eaten a lot of muscle candies it doesn't mean that you will become a stronger horse."
Nick watched the video in Tom's phone and looked how detailed was the anatomic change in his body. It wasn't just his shape but his internal organs and functions change as well. He got embarrassed when the video began to explain how the human dick becomes a horse one. It wasn't just his penis but his testes, urethra and glans which changed along with it. According to the video he was 100% horse, except for his human mind, thankfully for him.
"I'm going for the breeding equipment." Tom said leaving Nick watching the transformation video once again.
"So, it's true. I am really a horse now..." Nick thought without realizing that he was peeing like a racehorse at the same time.
