Mitch wished that there was someway that he could comfort Karissa more. Like share her experience. Have his own donkey ears and tail. Show her that she wasn't a freak. The thought came unbidden, like most people it wouldn't have changed anything, but most people didn't have an amulet that granted wishes.
Mitch felt the odd sensation of someone pulling his ears. It didn't hurt, it almost felt like his ears were made of taffy. Reaching up and feeling his ears, Mitch realized that he's made a wish. Just a normal stray thought and now he was getting exactly what Karissa had. Mitch was enjoying his transformation, one hand on his growing ear and the other around Karissa. She noticed Mitch beginning to transform and watched without a sniffle or sob.
As his ears finished, Mitch shifted uncomfortably and a long, thick donkey tail snaked out from behind him. Mitch's fur grew darker than Karissa's, but was no less soft.
"See? You're not a freak. We're two of a kind, you and me. It's not so bad is it?" Mitch said as Karissa reached over and hesitantly stroked both Mitch's ears and his tail.
Each stroke was longer and more confident. Mitch smiled, he was able to finally comfort and bring Karissa back to herself.
