"Hey there. Did you enjoy the bit of magic I used on those two jackasses?" I asked the ball boy as he finished pulling up his pants.
"That was you? Damn man, that was amazing. Do you come from a family of sorcerers?" He clearly was impressed, and the smile on his face along with the boner in his pants told me I made the right choice talking to him.
"Nah. Honestly, I just sorta came into this magic this morning. I've been testing it out, checking for limitations and such. So far I haven't hit any snags."
"Seriously? Just this morning? What kind of magic have you used so far?"
"Well, first I made a towel vanish, then there was a bit of sexy mind control, then petrification, then I came here and did some body modifications, age change, more mind control and donkey transformations. I mean, I know it sounds like a lot, but when I'm using it, the magic feels really simple. I just kinda wish for something to happen, snap my fingers, and it happens."
"Amazing! It's wish fulfillment magic, it's gotta be! With that kind of power, you could-"
"I could what?"
"You could...make me a powerful sorcerer too! You could just wish me to have strong transformation magic and BOOM! I'd be able to change spoiled rich guys like them into jackasses all day long!"
I grinned. I liked the way this guy thought. And if he was right, then I could probably wreak havoc on the school's pecking order. Powerful teachers could be made weak, weak students could become incredible sorcerers overnight. The potential turnabouts was too tempting to pass on. "Alright, I'll give it a shot umm...what's your name again?"
"I'm Luke."
"Good to meet ya, Luke. I'm Kain. And I'm about to give you a helluva power boost!" *Snap!* And with that, I made possibly the worst decision of my life. Magical knowledge flowed into Luke, along with lots of power to back it up. He grinned widely, and I knew I had succeeded.
"Come on Luke, let's go find someone to test your magic on."
"Oh, but I've already got a perfect subject right here."
"What? No way man, I gave you that magic and I can just as easily take it away, so play nice."
"Can you?"
"Yeah, it'll be a snap!" I replied curtly. But just when I went to snap my fingers and will away all the power I had given him, it occurred to me that my hands had been replaced with donkey hooves.
"Yeah, I thought that would be the case. Wish fulfillment is dangerous magic, it needs to be contained. And while I don't have that kind of power, I can at least restrain you until I find someone that does."
"You sonof-hawwwww bitch!" Fuck! It really was too late. I could feel my entire body expanding, my clothes tearing off me as my entire shape began to shift into a jackass. First my pants ripped in half as a tail sprouted out of my ass. I could feel my ankles rise off the ground as my toes melded into hooves. My entire balance was thrown off, and I found myself standing awkwardly on all fours. Next my chest began to expand, tearing my shirt apart at the seems. My arms began to grow longer until they matched my hind legs, and I struggled to stay steady. Fur began to spread from my hooves all the way up my legs, and as it reached my crotch, I could feel my cock becoming harder than it's ever been in my entire life. It felt like it would never stop growing. It felt so good, I began to forget about the humiliation and betrayal I was suffering. As the fur climbed up my body and reached my neck, the pressure on my cock was unbearable. "HEEEE HAAAAAAWWWW!" I brayed wildly as I experienced the most amazing orgasm of my life. I could hear the cum spraying all over the ground below me. For that brief moment, my mind had completely blanked on everything but the intense pleasure I had felt. But then, as my ears began to lengthen, and the fur spread to my face, it all came back to me.
"You cawwwwwn't do this to meeeeee-hawww! I'll ma-haaaaayke you paaay faaaaaaaw this! You baaast-awwwwd! Heee hawww! Hee haw! HEE HAW!!!" And as my words turned into brays, my face stretched out, forming a muzzle, leaving the transformation complete. I was utterly humiliated. I was enraged. I wanted nothing more than to stomp and kick and bite this bastard for doing this to me. But him? He just held up his finger.
"Sorry Kain, but the world has enough power hunger assholes in it without someone like you. Time to say goodbye." And with that, he touched his finger to my forehead, and I began to feel everything that I ever was slipping away from my mind. My intellect was replaced with instinct and my memories became blurs of places and things. I became calm, because there was nothing to fear. I was outdoors, there was grass, nearby there were two other donkeys like me.
I was a content jackass.
