Mitch hugged his girlfriend turned donkey-girl, stroking her wonderfully soft donkey ears. He watches her tail swish back and forth, the dark tuft at the end brushing his legs. There was just something about those donkey features that Mitch really, really liked. As he hugged Karissa, he kept his eyes on those features. They were all his thoughts. Mitch began to yearn to add to those donkey features. In his thinking, Mitch let loose the 'I wish...' thought and the amulet glowed and Karissa began to transform again. He couldn't help himself, he was lost in a lust to see Karissa become the donkey of his dreams.
Karissa, just getting calmed down after growing donkey ears and a tail, felt a warmth all over her face. Then, she felt it push outward. She let out a whimper as she realized she was changing again. Quiet tears rolled down a lengthening muzzle that grew more soft fur over it. Karissa reached up a hand and felt her new face. It wasn't a complete donkey muzzle, she had a mix between her old face and a full donkey muzzle. "Miiiawwch!" Karissa tried to say, but it came out as a half-bray.
Mitch had been watching the change, he had eyes only for her lovely donkey features. He was entranced as she transformed. Just as Karissa was getting up to shake Mitch, she fell back down into the sofa and clutched her chest. Looking down, she saw it seem to inflate. It swelled and filled her blouse, becoming more barrel-like. The fabric held, but only just barely. Karissa's breasts pressed out the blouse in two round ample spheres, they had grown as well, if only a little bit.
Karissa now really began to cry, which came out as a braying sob. She was closer to a full donkey, she had the ear, the tail, most of the muzzle and now her chest was barreling out. This was the worst day of her life.
Then...
