You were left speechless by your recent transformation, but inside you could feel it: an increasingly animalistic instinct. As you looked at your huge cock, you started to feel more like an ass than human. You couldn't say that you resisted the transformation, but for the first time the curse made you think that this was all right.
Martha, well, she had come to the island with a very specific purpose, to become a donkey and soon she would fulfill her dream. And at that precise moment, she began to lean forward.
"Yes, yes, yes heeaeewww" she began to cheer.... "My ass.....". It didn't take you long to understand.
Martha's ass was getting bigger and bigger, all while her legs took on an increasingly equine appearance and her fur grew. Martha was very thin, but with recent changes the dress she was wearing was starting to get tight.
"Yes, yes" continued an ecstatic Martha, her ass had not stopped growing, especially in a very short time it began to fill with brown fur, until it filled her ass completely. If it weren't for her still pink thighs, her lower half would have been completely that of a donkey. Even more so, when she turned with her back to you, and then bent over: you couldn't help but notice how her anus and vagina had also enlarged, darkened and above all present in the equine position.
You noticed how neither of you was able, as before, to stay in a perfect upright position, you slightly forward, burdened by the weight of your new equipment, Martha on the other hand, with her back decidedly bent forward.
"We're there, we're almost there." Martha shouted.
HEEEEEAWWWWWWWWWWWWWW
A huge bray made her falter.
HEEEEEEEEEEEAWWWWWWWWWWWWWWWWW
A second, even louder bray made her stagger instead. Standing on her back two hooves became increasingly difficult for her.
HEEEEEEAAAAWWWWWWWWWWWWWWWWWWWWWW
Finally, the third bray, made her lose her balance, falling forward to the ground. Martha didn't even try to stand up, she gripped the earth with her still human hands and let out another bray: HEEEEAAAAWWWWWWWWWW
“Oh my god Martha..” you said.
"AhahhahahahaheeeawWWWW" she replied without any concern, indeed with satisfaction "finally on all fours".
