Mary grinds her teeth in agony. She stops typing at her computer and brings a hand up and rubs her jaw, it felt inflamed. She opens her mouth and closes it trying to get it to pop, to find some relief but she can't seem to.
Suddenly she doubles over clutching her stomach, she gasps in pain as he jaw locks, it hurts. It's the most excruciating pain she's ever felt. She holds the desk for support as she clenches her eyes shut. Her teeth felt tight, her gums swollen, the pressure increased as she could feel her teeth swelling. She brings a hand to her mouth and gasps, her teeth were swelling. Slowly she could feel them changing, growing. They stretched out her gums and she could taste the blood.
She watched in horror as some of her teeth fell out, clattering on the desk, blood and Drool now pooling from her mouth. She screamed but no sound came, as she opened her jaw wider as her insicors grew longer and longer. Her teeth all began to sharpen. The pressure was too much, she forced her jaw open as it pops. Now her mouth wide open she can feel the muscles in her face changing to accommodate the new features. She doesn't notice her tongue growing longer and longer until it hangs from her mouth, she can feel the sharp razors on it. Then pain subsides, as her jaw throbs. She opens her eyes slowly and feels the changes, quickly moving to grab a mirror from her purse. She opens it up to see her new feline esque teeth and tongue and her mind races back to the vials.
