"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 an australian national symbol?," 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 broenish fur was starting to sprout on his hands as his fingers started to reduce. Soon, his hands reshaped into kangaroo front paws. 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 lengthened over twice their former size. He quickly looked back when he felt his butt and thighs were growing inhumanly large as a long thick reddish 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 arms and legs reshaping that make him to take a kangaroo stance instead. You and your classmates were staring at how his genitals were changing until he got a really weird and pointy dick which quickly hid inside him while his testicles moved above it. 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 a snout as the fur completely covered his body. He shook off the tattered remains of his clothes as he made his first jump using his stronger legs. He stared at the class, who in turn stared back at him in awe. Jay was now a kangaroo.
You were in shock in awe. Right before your eyes, you saw your classmate turn from a jockish boy to a massive kangaroo.
"Ah, you came out nicely!" Ms. Tomlin beamed. "You make quite a beautiful kangaroo, 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?"
