Liam continued brushing Mike's back, the already dark brown coat deepening to a midnight black that spread like a paint spill. Muscles pulled and hide quivered, the sensations strange but also exciting to Mike. This was real magic, not the 'poof' change he had undergone to be a centaur. How common was magic ere, anyway? This stableboy was certainly having no problem - was it a magic tool that anyone could use, or did the teen have abilities that helped?
"Um, if you don't mind my asking, are you a wizard?" Mike shifted his gaze back and forth between Liam's face and the slow but steady transformation of his equine back.
Liam chuckled. "Me? Nah. Though I do get to use magic, which is pretty special. It's all special tools and spells on the stall." He gestured around the stable. "We have lots of magic stuff in here for healing, grooming, and training animals. But only a few stalls allow the tools to be used on anything but a real animal."
"This is one of them, I guess." Mike grinned. "Do you change a lot of centaurs?" He had to shift slightly on his hooves, and realized his back was a little longer now.
"If they come in here, I usually handle whatever they want done." Liam smiled back, his eyes a bright, friendly blue. He was homely and dirty, and a couple of years younger than Mike, but there was something very appealing about him. "I love centaurs. Working on you is the best part of my job."
Conner was snuffling and rubbing against Mike's other side, and he absently rubbed her neck with his fist. "So, how long have you been working here?" Mike found himself wishing the tattered loincloth would fall off - he was curious about what the stableboy looked like. Then he felt his cheeks burn. What the Hell was he thinking?
Liam started brushing out his tail and running the bristles over his rump. That felt really good, and the oddly pleasant muscle clenching worked up into his rectum and thighs. His tail twitched, getting thicker and longer. "Oh, maybe ten years. I don't know exactly."
"Ten years!" Mike stared at the young teen. "How old are you?" He was so startled, he almost missed noticing that the black hide on his back was moving slowly down his sides on its own.
Liam looked thoughtful. "Somewhere about 20, I guess. Maybe a little more." He grinned up at Mike. "One of the perks of the job. I stay a boy as long as I work here. I can stay here a hundred years and if and when I decide to quit, I have all that experience and I'm still only apprentice age!" He gave Mike's rump a pat with his free hand. "Made possible by centaurs like you."
The bristles slid over Mike's testicles, and his eyes widened at the very intense sensations. He stiffened, eyes widening, as he felt them swell and grow heavier. He also shifted on his hooves as his legs lengthened slightly. Conner lipped at his human arm, her lips pulling over the skin. The grooming was very relaxing, especially combined with the stableboy's attentions. He had to concentrate on Liam's words. "Oh! So using magic on centaurs keeps you a kid? That sounds sorta weird. If you do a lot of centaurs, do you get younger?"
"No!" Liam chuckled as he shifted around to Mike's right hind leg. "I sure do not want to get younger! Working here has a lot of benefits, but if I got too young I'd loose one of the best!" He stopped grooming Mike and tugged at his loincloth. The filthy rag fell away to reveal huge, equine-looking sexual parts. A flat-tipped cock was slightly pushed out of a fully animal black sheath, with impressive black testicles hanging underneath. They were vastly oversized for the boy, but probably not the size of a horse's. Maybe a jackass?
"Wow!" Mike flushed again, though he was pleased by the reveal. "I bet you are pretty popular."
The stableboy nodded. "Not so much with the girls, because I am too big for them. But there's hardly a boy in Lavenguard who hasn't whacked me off, and a lot of the mares and jennies here enjoy my attentions." He stopped brushing Mike's leg and turned slightly to give the centaur full front. "You want to try it? Centaur's can't reach their own, and I bet you get frustrated sometimes."
Between Conner's attention and the slow transformation, Mike had been coming erect. This was the first time for him as a centaur, and the sense of mass and weight was starting to get distracting. He did want to feel the teen's equine parts, but social taboos from his own world made him hesitate. Liam acted like this was all normal and acceptable, even saying that it was common for other boys to handle him.
