Caught up in the moment and in Martha's words, which had previously been illogical for you, you actually hadn't noticed how your feet felt more swollen and a little sore. You lowered your head towards the pair of Nike Air you had just bought no more than a week ago, the white of the new one stood out against the dirty white, torn in some places, of Martha's Adidas, worn by the years. Yet something was wrong, both toes of your Nikes were definitely more swollen than they should be.
"Oh, I'm sorry" continued Martha, "the shoes are so new and will soon be destroyed".....ahhahahahahhhHEEEEEAWWWWWW
You didn't even have time to think or reply before Martha spoke again: "Oh, I think my physical transformation is about to begin..."
She whipped around to face you and there was something strange, a bump above her butt. A growing bump, causing Martha to bend over.....
"Yes, yes.....HEEEEEAAAWWWWWWWWWWWWW"
A mighty bray came from her mouth, as the bulge grew and grew, with a tear - RIIIIPP - it tore her underwear and continued to grow, coming out of her dress.
Is it, is it a tail? You thought, all while brown hairs grew on her skin and a black flake at the end began to form.
“Martha, my God, you have a tail!” you yelled at her.
Hearing your words, she turned, remained silent for a few moments, and then said, "And you, my dear, will soon have hooves."
Moments later, the stitching of your shoes began to give way, the toes disintegrating. The look made you horrified: where once you had fingers, there was now a single solid mass, black, progressively solidifying. Martha was right, you had hooves.
