Although he wasn't clear on what was going to happen, Chris quickly pulled his clothing off. The huge lion watched him without moving, golden eyes staring impassively. When Chris was fully naked, he rumbled "Come to me."
Chris shivered a bit at the raw power in the lion's voice, and realized that even thought he male was humanoid, he had large teeth and sharp claws. Taking a deep breath, he moved to stand before the magnificent beast, trembling a little.
"Now, say that you want to be my lioness, and that you accept any and all changes to your body and soul that I choose to make."
Chris hesitated. His soul? But the lion's eyes were mesmerizing and the heavy musk filling his nostrils was making it hard to think clearly. "I want to be your lioness. I accept any changes you want to make to my body and soul." He jumped as hot and cold winds suddenly whipped around him and then became a heat that enveloped him.
"Good." The lion rose and pulled Chris against his chest. "You have been accepted into the magic. He lowered his head and pressed his muzzle against Chris's mouth, forcing his lips open with a probing tongue. Saliva, thick and warm, was pushed into the young man's mouth, and he swallowed. More followed, and one of the lion-man's massive paws slid down to massage Chris's butt. The pressure and rubbing felt good, focusing the warmth into hot spots in his rump and crotch that got intense, yet felt wonderful. The sensation in his crotch began to fade, but his rump increased its feedback, getting slick and hot and needy. A clawed finger slipped into an opening that had not been there a minute before, and Chris gasped.
At that moment, the lion-man grabbed Chris and spun him around, then shoved hard so that the young man fell forward. Chris caught himself with his hands, then cried out as the massive male landed heavily over his back. There was a mind-numbing shock as the barbed lion cock shoved into his new cunt, and then Chris shouted, moaned, growled, and roared as his mate drove hard and deep, each thrust making the former human into a golden-furred lioness. The male changed as he mounted her as well, the humanoid form rippling back into the massive but normal male lion he had been during the day. The lion roared as he shuddered and exploded into his female, filling her with his seed. Chris, now fully a normal lioness, roared as she was filled.
The male stayed in her for a few minutes more, both of them damp and reeking of rut. Then he pulled out slowly and they licked each other clean. It took a while before Chris could think again, and he.. no.. she felt more content than she could ever remember. The lion nuzzled her, then shifted back to a humanoid form and resumed his posing by the rocks. Chris watched him adoringly. She was his. She knew that she had given up her humanity, that she was now an animal. Not for the night, not for a week - forever. Something had changed inside her, not just instincts and needs, but her core self, her... soul? Her humanity had been stolen. No. She had given it up freely. And because she had agreed, because she had not fought, she was a lioness.
Chris stretched out on the ground, still flushed from mating. Her human life seemed meaningless to her now, and all that mattered was pleasing her mate, being part of the pride. She did not mind being the only one stuck as an animal. She was still special.
