A few moments later Ty was sitting on a soft patch of grass with his arm around the deer's back, his fingers stroking through the fur on her side gently as he told his story.
"And so that's really it." Ty concluded, having related the details of his birthday so far.
The doe considered all she had been told and closed her eyes thoughtfully. "Such a strange thing to happen to you." She commented. "And yet the second thing you did with this... ability." She opened her eyes and stared at the young human with a smile. "Your power, as you call it..."
"Yes." Ty nodded, smiling back.
"Well, the first thing you did, Tyler, was make me the first and only sentient animal in the entire world." She chuckled. "You could have done anything, I suspect. Yet you chose to give me the gift of a mind. Of intelligence, speech, and reasoning." Her gaze into his eyes deepened, almost seeing inside of him.
Ty gulped, staring into the doe's beautiful turquoise eyes, and for a moment he lost himself. "I... is it a burden? Is that what you're saying? Did I force it on you?"
The deer craned her neck back in shock and she leaned her body against Ty. "Goodness no! It's... it's wonderful! I couldn't have imagined this before!" She stood gently, gracefully, and giggled happily. "I... I see in color, Ty! In color! I didn't know what color was before, but it is so beautiful, so overwhelming. I think, not just of instinct, of survival. I want to learn, and see, and do, and create! How many deer can claim the same ability?" She turned to face him, prancing merrily, and smiled. "I am glad for your gift."
Ty sighed in relief and also stood. The doe approached him gently and stared up at her human friend. Her gaze grew deep again. "And... I'm glad for you."
Ty knelt down on his knees and wrapped his arms around the deer's neck gently. She grinned her approval and closed her eyes in pleasure as he massaged her neck. "Would... you let me give you another gift?"
She opened her eyes and smirked playfully. "Oh? What did you have in mind, Tyler?"
"I can't help but think if your new mind is full of such possibilities, what could a new body do?"
"A new body?" The doe's excitement peaked. "Truly? You would change my form? What a wonderful idea! What would you make me? Am I still to be a deer? Do you wish to make me human? Something between the two? Or... or am I to be something else entirely?" Her tail wagged like a dog's in pure joy.
"Easy, easy." Ty laughed, seeing her excitement. "I want you to still be a deer. I was just thinking... why not have a new body to match your new human intelligence? Something... in between the two."
"That would make me..." The doe's eyes widened. "Both human and deer?"
"Exactly. A mixture of the two. A humanoid. A humanoid deer." Ty leaned in close just inches from the doe's nose. "An anthromorph."
The moment was fast approaching something surreal. "Would... would you make it pleasant for me? This change?" She could hardly deny her animal sexuality anymore, and she hoped very much she wasn't misreading her new changer's intentions. Or his pheromones.
"Absolutely." Ty whispered, and began to concentrate his sheer force of will. "You'll begin to shift, slowly, from a complete female deer in body to a 50/50 mix of female human and female deer. You'll grow tall, strong, beautiful, and busty. As a lovely animal woman should be. The process, your changes, will feel pleasurable. Intense." He gulped and saw her licking her lips in anticipation. "You'll become aroused from your change. The arousal will be nearly unbearable and you'll need sex."
"Oh, yes! How wonderful!" The doe shivered slightly, her eyes blinked, then widened. "O-Oh!" She gasped. "Oh!"
"It's starting?" Ty gaped.
"Y-Yes!" The doe's back legs started shaking. "And very soon you're going to have a very very horny deer woman who will need satisfying, Tyler." She dropped her head, closed her eyes, and moaned, savouring the strange feelings inside of her. "Maybe... maybe very soon."
