"Chelsea, how about you come on up?" Ms. Tomlin said, pointing at Chelsea. Chelsea got up and walked to the front of the class. "I take it your a fan of tigers?" Ms. Tomlin asked. "Yeah, they're one of my favorite animals." Chelsea replied. "Well then, are you ready?" Ms. Tomlin asked as she pulled out a black potion from her desk. "For what?" Chelsea asked. "Oh, you'll see..." Ms. Tomlin grinned. "Now drink up, but leave some for the rest of the class." Chelsea took a small swig of the liquid, and began to stumble backwards. "How do you feel?" Ms. Tomlin asked. "A little weird..." Chelsea replied.
Suddenly, Chelsea fell to the floor as a wave of changes began to flow through her. Orange fur began to sprout from her hands and spread across her body. Her nails sharpened into claws as her hands and feet retracted into paws. Black stripes began to appear all over her body as she grew several more sets of breasts. Her spine started to elongate as a long tail burst from her pants. Her already large ass began to widen even more until her clothes had been torn off. Her face extended into a feline muzzle as her nose flattened and turned pink. Her ears rounded out while her blonde hair retracted into her head. Soon, the fur had covered her entire body as she let out a powerful roar.
You could only stare in shock in awe. Before your very eyes, you saw a girl transform into a tigress. Chelsea began to walk around on all fours, taking in her new form, smirking in satisfaction.
"Ah, you came out nicely!" Ms. Tomlin beamed. "Why don't you go wait at the back of the class?" Chelsea did as she was told, licking her chops as she went to the back. "Now, would anyone else like to volunteer?" the teacher asked.
