Damon continues to feel strange as the mare continues to lick his dick. She wouldn't let go and Damon was enjoying it.
What he didn't know his dick became big and change into his new equine dick. "Good your changes are coming along well." The mare talk. But Damon didn't mind. He was in pleasure.
"Don't stop." He told the mare. "As you wish. You will make a perfect stallion." Black hide and fur grew all over his body matching his hair color.
His hair then grows down into his new mane as his body bulk up. His hands and feet fuse together into his new hooves.
"Please stand on four lega for me." Damon did what the mare told him. He was now on four legs.
His face pushes out into his new horse snout as a tail comes out from his behind as white fur appear on his chest.
Damon was now a handsome stallion. The mare let go of his dick as she looks over her new stallion mate.
"You'll make a perfect stallion." She then nuzzles him as Damon nuzzles her back enjoying his new stallion hood.
