Ty recalled the part of his wish where he had made it so humans interbred with other species and realized, this would definitely be more fun if he was a girl. This majestic big cat would get to make Ty pregnant with his seed. Ty would probably feel even more pleasure when he got fucked. He knew he HAD to do this.
And so, before the lion could mount him, Ty wished for himself to turn into a girl. Instantly his body reshaped into her body. His figure turned more petite and his skin softer all over. His shoulders narrowed and his hips widened to child-bearing proportions. His nipples grew sensitive and flesh swelled under them as he developed soft breasts. His penis slowly receded away and his testicles were pulled up to become part of a female reproductive system, his scrotum turning into a vaginal mound. Within seconds, she had turned into a girl.
Once Ty finished changing, the lion went from intrigued by his pheromones to intoxicated by her pheromones, just as Ty had hoped. Its shaft rubbed against her newformed vagina and clitoris, and a shiver went through her as in response to his phallus's spines, she felt herself ovulate, her body producing fresh eggs for him to fertilize.
He pushed inside her and she moaned loudly at the sensation as he slowly filled her up. The large, thick, pointed shaft practically buried into her, feeling like it would never come out. She struggled to hold herself up with him inside, and as he slowly began to thrust in and out of her, intense shocks of pleasure shot through her body as she jiggled and convulsed from the sensations.
The lion's pace was irrepressible as he pounded himself into Ty's freshly-formed pussy, and she felt totally overwhelmed by the sensations. She orgasmed uncontrollably around him, and her arousal surged only higher as the surface of his shaft dug into her vaginal walls as she clenched around him.
This was a real baptism of fire for her new sex- she couldn't even ease herself by rubbing her nipples or clit, she just had to desperately hold herself up on her shaking arms and legs. She moaned and whimpered in astonishment as his shaft brushed against her G-spot, giving her pleasure her brain had never even known was possible.
At last she heard grunts and growls that told her the male inside her was approaching his peak, and soon he finished inside her, his warm cum filling her up. As it touched her passage, she felt herself reach a second orgasm and clung to him, making his spines rake her again and her mind go blank with pleasure in response. She practically collapsed as they both came down from the high.
Inside Ty's newformed womb, the feline seed that had filled her was reaching her deepest point, and the eggs that the male who had produced them had stimulated her to release. They swarmed around them, broke through, and made Ty pregnant with the lion's pups.
