"How about you, Jay?" Ms. Tomlin asked the local jock. You watched him get up and head towards the front of the class.
"What do you think of becoming a beautiful stallion?," the teacher said. "Pff, I don't think that's possible." Jay grimaced. "I can't be hypnotized."
Ms. Tomlin just grinned and pulled out a bottle of some kind of black liquid. "What's this for?" Jay asked. "Oh, you'll see..." Ms. Tomlin answered. "Now drink up, but leave some for the rest of the class."
Jay stared bewildered at the bottle for a moment before he took a small swig of the potion as you and the rest of the class just watched. "How do you feel, Jay?" Ms. Tomlin asked. "A bit funny..." Jay replied.
Suddenly, Jay collapsed onto the floor in pain. He freaked out when he noticed thick brown fur was starting to sprout on his hands as his fingers started merging together. Soon, his hands reshaped into hard black hooves. Jay's body began to gain a lot of mass while his clothes were torn off. His shoes and socks were torn off as his feet changed into hooves. He quickly looked back when he felt his butt and thighs were growing inhumanly large as a long dark brown tail forced itself out of his pants, tearing them off. He was completely naked at that moment and, ashamed, he tried to cover his privates but he couldn't due to his lack of balance that make him fall on four. You and your classmates were staring at how big and dark his dick and balls were getting until he got a complete horse set which quickly hid inside his new sheath. His still human head was red of embarrassment while his neck began to extend upwards and his ears grow longer and pointier. Finally, his reddened face pushed outwards and formed into an equine snout as the fur completely covered his body. He shook off the tattered remains of his clothes as he let out his first neigh. He stared at the class, who in turn stared back at him in awe. Jay was now a huge clydesdale stallion.
You were in shock in awe. Right before your eyes, you saw your classmate turn from a jockish boy to a astounding black stallion.
"Ah, you came out nicely!" Ms. Tomlin beamed. "You make quite a beautiful stallion, Jay. Why don't you go stand over there for the time being?" Jay reluctantly did what he was told and walked towards an empty corner of the room. Ms. Tomlin turned to the rest of the class. "Now, would anyone else like to join in?"
