While waiting for the next test, the lab tech starts to notice some changes on her, too. Her ears start to elongate, her butt expands and a small tail starts to grow out just above her butt cheeks. "No! That's impossible! I'm not supposed to change! I'm a lab tech and not the test subject!", she cries with fear. She tries to fight her changes but there is no way to stop it. Her jaw slowly pushing forward, making it hard for her to speak.
You start to smell the nearby mare and get aroused by her again. She notices your erect member and becomes also aroused.
