“I'm sorryheeawww,” Martha continued, “I wanted to be a donkey hheeaaww so bad that I'm heeaawweee turningndheeeawww much fasterheeeaawwww than you.”
Her teeth were starting to stick out, to turn yellow, to flatten. Her eyes, her arms, her hands were the last holds of humanity, even her red hair had started to fall to the ground.
"Martha...Martha....I love you" you found the courage to tell her your emotions.
“I lovheeeawwww youheeawwwww tooheeeawwwwww” Martha replied as her words became more and more braying.
Your transformation had momentarily stalled, after the growth of your cock, while hers proceeded very quickly. With one kick she freed herself of what remained of the attached Adidas, the sole and the back heel, now revealing two hooves indistinguishable from those of a normal donkey, not only had her teeth become enormous, even her nose began to merge with lips, and to push forward.
In that moment you found the strength to come closer and give her a kiss, until her mouth still had a human appearance.
"Martha soon I will be like you too....." you told her in a kind and reassuring way.
HEEEEEEAAWWWWWWWWWWWWWWWWWWWWWW
She responded with a huge bray, probably unable to speak by now. Her back and torso began to enlarge, starting to tear at her dress, her hands curling into fists, marking the beginning of the transformation into hooves.
You remained to watch her as her humanity, as she wanted, ran away, in the same position where once there was a beautiful girl, now there was a complete ass. On the ground, her dress shattered.
