"Jess!"
But the girls realized that their was nothing they could do but watch at the changed wracked their friend's body. Jess' feet lengthened into feline paws and her legs snapped into the hindquarters of a large cat of prey. A long reptilian tail pushed out of her pants and grew to an impressive four feet long. Her clothes tore free from her body as muscles pumped larger and more defined. Her arms grew fur to match her hooves and changed into the complete forelegs of a goat. Her torso lengthened as it gained a few more segments of reptilian body. Another set of scale covered breasts grew in as well underneath the first two pair.
When it seemed as though the changes had stopped the two girls approached their friend cautiously. "Jess? You OK?" Jess remained crouching on the floor on all fours breathing heavily. As the girls got closer they heard what sounded like growls coming from Jess. When the got within a few feet they received the shock of their lives.
Jess whipped around her head to show her face had changed as well. It was now the snarling fanged face of a mature lioness! The beast that was Jess snarled at the two girls menacingly.
"Jess! It's us! Lina and Amy! You're best friends!" Lina tried to reach some remnant of her friend trapped inside the monster.
The animal seemed to pause for a moment but any other sign of recognition instantly dissolved as she coiled for the pounce. Amy and Lina screamed at the top of their lungs as the ferocious chimera dove through the air at them, fangs gleaming for the kill!
"HEEL!"
