Michelle spent the night in her nearby tent. As it was a cold night, she kept her clothes on during she slept.
She woke up with a terrible headache. Carefully touching her head, she realizied in horror that something had grown out her forehead. Terrified she ran to the lake, looking at her mirrored image. She screamed, when she saw two small antlers, which had appeared on her head. "This...this is impossible!", she cried. But she knew that it was for real. She actually could feel her new antlers. And they were still growing. Michelle still looked at her mirrored image. She could see her antlers growing. Growing from two pointers into three pointers and it wouldn't stop there.
She watched her image, terrified but yet fascinated, until she noticed something else going on. A pressure was building down in her pants. She changed her view. Looking down to her pants and gasping in shock as the buttons of her pants popped open and a small but growing penis fought its way free of her restrictive clothes.
"Noooooo!", Michelle cried in shock but at the same time she began to smell the odor of the woods. And the pheromones of nearby does. Her penis suddenly stiffened and she moved her hand down to touch it carefully. It felt good. Arousing. She began to rub it lustfully. Licking her lips, as her face slowly pushed out into the muzzle of a deer. A small tail wriggled free of her pants and growing hooves shredded her socks. But Michelle didn't care. She only could think about the does grazing peachfully a few hundred yards away. She rubbed her member harder and harder, which made it grow even more. And so were her antlers growing. Her body bulked up, straining her shirt and pants. Seams ripping as she shifted more and more into a virile stag.
