"...turn us into tigers of the opposite sex?" Stephen asked.
"Yes," I said.
But Stephen asked again, "You can honestly make Theresa a male tiger and me a female tiger?"
So, yes, their fantasy was a bit out there. But as I said to Stephen, I wasn't about to judge. It was also for this reason that I thought I could bring both of them into my little group. If I were to leave them after tonight, there was really no way I could let them have their fantasy beyond tonight. If I brought them in with me, I could let them keep living their fantasy. I simply reiterated, "Yes, I can."
Stephen sat back in the couch. "I'm sorry, I really just can't believe that. It's impossible."
I was afraid that he wouldn't believe me. I felt pretty confident that I had Theresa's belief, however. So I realized I was going to have to do this the hard way. I just hoped Theresa wasn't going to be upset with me. "I'll just have to show you," I said to him. I looked at Theresa. "Theresa, get ready."
"For what?" she asked quizzically. I just grinned at her and wished that she would transform into a virile male tiger. For the sake of safety, I wished that she would not have any urges to physically harm the rest of us. After a few seconds, Theresa exclaimed, "Ooh!"
"What's wrong?" asked Stephen. He looked concerned.
"Something's poking me in the back," she said as she stood up from the couch. She felt at her lower back just above her ass. "What is going on?" she asked with a loud groan. She put her hand on her ass and felt around to determine from where she felt the discomfort. Suddenly she lurched forward, apparently involuntarily, as if she was forced to move that way. Then a tail burst out of her clothing. It pushed her shirt up and forced her pants down as it continued to grow.
Theresa spotted her new body part and looked both stunned and amazed. “Is it real?” she asked. She put her hands on it gingerly and immediately pulled them away when she found that it was real. "Oh my god!" she exclaimed with excitement. Her tail continued to snake its way out of her clothes and grow longer. She was soon able to move it back and forth. This served to make her much happier. "I have a tail!" she practically squealed.
Just as she gained control over her tail she began to feel a pressure build up in the front of her pants. A very noticeable bulge could be seen and it was growing steadily larger. Theresa seemingly cast off her somewhat prudish nature and quickly unbuttoned her pants and forced them down. She marveled at the sight of the cock and balls that had grown out of her body.
"Oh...my...god," said Stephen. "It's really happening." He stared at Theresa's new body part as much as she did. Then he looked at her face. "Now it's happening in your face!"
Theresa's teeth had grown sharp in the appropriate places and a set of whiskers pushed out of her face. Theresa felt at her face and seemed happy. "This is wild," she said. Her voice sounded deeper and more guttural.
Sounds of ripping material echoed in the room. Theresa's shoes ripped apart as her feet enlarged to a much bigger size. In addition to growing larger they had begun to change in form as well. Her nails had thickened and twisted into claws and fur sprouted all over her feet. Her feet steadily shifted into paws.
Next her legs grew larger and thicker. Her pants quickly tore apart to reveal legs that were enhanced with muscle and also had fur growing all over them. Theresa continued to look happy at her changes. As her fingernails also reshaped themselves into claws, she tore at her shirt and ripped it off her body. Her breasts had already pulled back into her body. There was little about her current appearance that would make you realize she was really a female.
Fur sprouted over the rest of her body and changed into a combination of orange, black and white. She possessed a nice set of stripes as her fur grew in. Her legs had grown large and her entire body was growing larger in both size and mass. Her feet completely changed into paws and now her hands did the same. As this took place she was forced into a four-legged stance. Her spine shifted posture to allow for this position. There was a pained look on her face and she growled slightly as this occurred. "It hurts," she managed to say through her sharpened teeth in a voice that sounded nothing like her.
Her new cock transformed into a furry tiger sheath. The rest of her body was now that of a tiger with the exception of her head and face. Her ears grew in size, became rounded and shifted to the top of her head. Her hair slowly disappeared into her head so that she looked like a real tiger. Her eyes changed in color to a bright yellow and her face slowly but surely pushed out into a muzzle. All signs of humanity in her voice were replaced by the growls and roars of a tiger.
Her transformation was complete and she was now a fully male tiger. She looked to be about ten feet long and had the look of a dangerous predator. Luckily she wouldn't have any urges to attack any of us. She moved her head from side to side as best she could. I assumed she was trying to get a full sense of how she now looked. She moved her tail back and forth with ease. Thanks to the large floor space she bounded around in a circle a few times in order to adjust to how her body now moved and responded.
Then she caught sight of me. Suddenly she...
