James let out a moan as he looked down to see that his cock was the first thing to start transforming. A sheath formed around its base as his balls grew larger as his shaft grew larger and formed a flared equine tip and medial ring as precum leaked out of the tip. His now equine cock started to soften a little, but hardened again at the close proximity to a mare.
James had always been a pretty fit guy but the transformation increased his muscle mass, even more, leaving him more and more buff as black fur started to spread out from his crotch. White stripes started to cross his body as he moaned again as it turned into a bray as the fur reached his neck and his voice box.
Alicia smiled as she looked down at his feet that had hardened and retreated into his legs where they formed into hooves. A nub formed from above his butt as his tail formed. The transformation finished as his face pushed out into a muzzle and his hair turning into a mane as he brayed loudly.
"Mmm, what a handsome stud you are," Alicia said with a smile as she moved in closer to the newborn Werezebra stallion and brushed her hand against his cock. "How do you feel?"
"Great," James said as his cock hardened more. "I feel so strong and powerful like I could run forever..."
"Mmm, I'm glad to have you in the herd finally," Alicia said with a smile as she nuzzled James and kissed him gently. "Though, you're going to have to finish your transformation before we can do anything else. I want this big cock inside me again..."
Alicia turned around and pushed her tail to the side again. James knew that he'd need to finish the transformation by mating with her once more, and this was his best chance. He looked down at his large cock which was considerably larger than when he was human, and he was more than happy to give it a test drive.
He placed his hands on Alicia's flanks and pressed his flared cock tip against her vagina as he prepared to take her as a stallion for the first time.
