A small and slutty goblin

"Y'know," Tom began, trying to sound casual, "stuff like elves and dwarves are kind of overdone."

Smiling, his wife nodded her head. "I would agree, but that's more my opinion on them appearing in fantasy stories, not becoming one."

"But think about it: what would really be that different? Pointed ears? Getting shorter? That's kind of boring. You should become something more interesting."

"You don't have to convince me, Tom, I told you to choose," Sarah reminded him. "Stop beating around the bush and tell me what you're getting at."

Holding up the coin, he just started with a single word. "Goblin." Her eyes went wide, and Tom knew that she was thinking the same thing as him. "Now that would be a real change, wouldn't it? Not just small, but kind of monstrous and energetic." He didn't mention that the idea of fucking a goblin was something he might have masturbated to before, once or twice.

"Sounds good to me, but make sure it's not just physical," Sarah added. "Make me really be a goblin. Not to the point I forget who and what I really am, but let's indulge in this if we're going that far, y'know?" Completely in agreement, Tom rubbed the coin and made the wish. I wish that Sarah would transform into a goblin version of herself, one influenced physically and mentally by how we perceive goblins in fiction. She won't forget who she is, but her personality and attitude will change to fit the stereotypes we have. The coin heated up, and the changes started.
