"Oooo, I like how you're thinking." said Sara, glancing over at Toy, who seemed not to be picking up on what was going on in their heads. Joey liked how Jill was thinking too. He had found Jill's transformation from busty Zebra girl into well hung Zebra shemale very arousing, and he found his eyes unable to stay away from the massive equine shaft dangling between her legs.
"What do you say Toy?" Sara asked, sauntering over next to the obviously still clueless unicorn.
"I'm happy to serve my lady however, err.. she(?) desires." Toy replied.
That was all the prompting Joey needed. "I wish Toy would become a sexy female unicorn for Sara."
Toy's eyes widened as he heard Joey's wish, but it was too late to stop as the magic washed over him, initiating his changes. For a few moments, nothing seemed to happen. Then Joey noticed that Toy's broad muzzle seemed narrower, his eyes wider, the overall effect making his face seem somehow more... feminine? His hands became smaller and more delicate even as his arms began losing bulk. Joey saw that even though Toy wasn't getting any shorter, his legs were growing longer even as his torso shortened, giving him a leggier silhouette. As his legs grew longer, his calves slimmed, more of his mass concentrating in his thighs, which were starting to look less bulky and more... curvy as fat began accumulating there. As the changes reached his hips the first big changes occurred, as with a series of cracks and snaps his hipbones spread wider and wider. As his hips widened, Toy's massive cock twitched and shrank, his balls dwindling until with a double pop they pulled up inside him, tunneling through him to create a cavernous horse pussy behind them as they nestled on either side of Toy's newly formed womb. With one last twitch, the vestiges of Toy's once impressive manhood nestled in the folds of his dark pussy lips, leaving Toy with fully functional set of female genitalia.
Toy moaned, a new breathy high sound, each inch off his cock having raised the pitch of his voice until it settled in a melodious alto. Toy's ass began expanding, each pulse of growth seeming to pull mass from his waist, deepening the hourglass shape of her torso even further. With a crunch, Toy's shoulder's narrowed and her spine arced, pushing her chest out in preparation for her final changes. Toy's pecs softened, receding into his chest even as her nipples puffed out and her areolas expanded. Then, even as Toy moved her hands to tweak her newly sensitive nipples, the flesh beneath bubbled and swelled into two pert teacups, protruding from her chest. Toy rubbed her hands all over her new breasts, kneading the small mounds. As if in response, both breasts quivered, before swelling, larger and larger, overflowing Toy's hands as they grew past teacups and into full, soft teardrops the size of grapefruits. Toy sighed as her grapefruit sized boobs quivered again, before ballooning into a pair of volleyball sized knockers. Toy wrapped her arms around the masses of expanding tit-flesh, pressing them together and giggling at the massive valley of cleavage created.
Sara had clearly been enjoying the show, her cock standing proudly at attention. She moved to fondle Toy's new assets, causing Toy to moan loudly. Toy blushed, giggling as the met Sara's eyes, before looking down shyly. That put Sara's cock square in her view, and she moved both dainty hands and began stroking up and down Sara's impressive length. Sara responded by bodily lifting Toy up off the ground and positioning her above the head of her cock. Toy squealed in surprise, but began bucking her hips to slide her moist pussy lips along what she could reach of Sara's member. In no time, Sara was thrusting her cock in and out of Toy's pussy, Toy's tits bouncing with each thrust.
"Well they're clearly enjoying themselves. Isn't it about time we join in?" Jill asked Joey innocently. Joey was about to make the wish that would hop him across the gender divide when Jill placed a finger over his mouth.
"You know, I think you've sat on the side lines long enough. Isn't it about time you got in touch with your inner animal?" Sara said.
Joey's mind whirred. She had a point, but there were so many choices? Which one to go with. He could become something African like Jill and Sara. Or go with something mythological like Toy. Or something else entirely.
