"I'm furry..." She gasped. "I'm a furry! Make me... half animal..." Her masturbation reached its peak and she was nearing orgasm.
"Not yet..." Ty bound her hands to her side and left the startled girl staring back at him in sexual desperation, unable to get her hands down to finish the job. She squeezed her legs together and humped the air, but that wasn't nearly enough.
"Please!" Becca's cheeks burned.
"What species?" Ty leaned up, watching Becca's eyes widen.
"Ohhh..." She moaned, pussy juice flowing into a puddle beneath her on the floor. She looked away for a moment panting and then looked up at Ty with a sheepish grin. "Something... big. And strong. And scaly."
"Ohh?" Ty's eyes lit up. "Can we be more specific?"
"A dragoness." Becca whispered. "A huge sexy rainbow dragoness."
"Oh, fucking challenge accepted." Ty cracked his knuckles, and began.
Becca's arms began to move again and she realized she was free to finish herself. Her hand shot down to her pussy and began working it again, but something was wrong.
"You won't be able to cum until you've changed fully." Ty whispered in her ear. This made her arousal grow beyond anything she had felt before, and her entire body shuddered as she came *close* to cumming but couldn't get over the edge.
"We'll start with your flesh..." Ty said, rubbing his hands over her shoulders and waist. He willed her skin to turn to hardened dragon's scales. Rainbow colored dragon scales.
Becca bucked and thrashed wildly as little by little her skin seemed to be drying out. Slowly, she began to crack all over and tiny flecks began to rise over her skin. She looked down at herself, furiously masturbating, and gasped as slowly the forms of dark brown scales began to rise and grow over her from head to toe. Her hair, long and dark, began to fall from her skin in clumps.
"Holy fuck!" She gasped. "Yes! Yes! YES! I'm going to be a fucking dragon!"
Her enthusiasm was met by physical bliss as every inch of her tingled with delight. Slowly, the scales grew and became prominant all over, armoring her in natural plates of cascading reptile teardrops that seemed to gleam every colour against the morning light. Her fingers sank inside of herself desperately and she brushed her other hand over her hardened beautiful new skin, every flawless and glossy scale more sensitive and pleasurable than human flesh could ever hope to be. Even her nipples, perky with arousal, were covered in tiny gleaming scales.
"Now to increase your dragon features." Ty said, holding her free hand and willing her to progress.
"Yesssss!" She hissed, a slimmer and longer forked tongue shooting from her mouth as her fangs and claws grew in. She clenched Ty's hand tightly as she began to fill with muscle, losing her slight paunch and instead gaining shape and definition across her whole form. Her shoulders widened, her nose began to flatten, and her ears began to grow. Behind her, a small foot long tail flicked out behind her tightened ass.
"Oh God yes. More!" Ty willed, squeezing her hand as tightly as she was his. She arched her back as her dragon features increased. Her gleaming rainbow scales flexed with her growing physique, and while she was still clearly female, her breasts growing bigger and heavier too, her natural strength had doubled to gorgeously athletic proportions. Wicked claws grew from her toes now and her feet and hands began to grow heavier and more powerful. She managed a look of pure ecstasy as her nose flattened to two slits on her face, just as her head crackled and her jaws began to grow out.
Now the shimmering dragon girl's tail whipped on the floor as it grew to three and then four feet in length. Ty held her massive paw in his hand and to his startled amazement the dragon creature began to *grow* in size as she progressed. Gaining strength and definition all the while, her breasts increased to two massive pert orbs, she arched her back as her claws teased her thick reptilian pussy and hung on as she doubled to twice her size, growing huge and intimidating. Her face grew longer and longer still while two small wings jutted out from behind her shoulder blades. Horns burst from her face, her scales grew more jagged and wicked looking. She moaned in a deep and ferocious voice, wings smacking over the table and chairs as they quickly grew, her head and longer neck falling back down the stairs to the living room, tail smashing out the drywall by the fridge.
"FUCK!" Becca screamed, a deep reveberating cry, as she positively filled the entire kitchen and living room, and spasmed her incredible body as she completed her transformation into a giant powerful sex crazed draconian. At once, her release came, lighting her fire and sending her nostrils smoldering. Ty hopped out of the way as the dragon cried out with a triumphant roar and had the hardest orgasm she had ever experienced.
And, Ty realized, she wasn't even fully grown yet.
