Normally I wouldn't link to merlin/arthur fic, but this is something special in that it's actually quite good.

in which merlin accidentally turns himself into a girl for a few days, because sometimes these things just happen.

Merlin accidentally turns himself into a girl. Short and sweet.

Girl!Merlin

Wherein Merlin accidentally turns himself into a girl. "Apparently, unknown to Merlin thus far, 'you look nice' in Arthur speak is in fact code for 'I would like to sneak down to your chambers at night and do all sorts of filthy things to you and your new ladyparts'. And apparently, also unknown to Merlin, when he replies with 'bugger off', he actually means 'I am surprisingly okay with that, and Christ, please do that thing with your tongue again, don't stop now'."

"Merlin," he says, loudly and accusingly, eyes wide, "you've got tits!"

Gauis looks at Merlin, and for the first time since Merlin woke up missing a Y chromosone, doesn't do a double-take. Merlin grins at him. "Well done, thank you, what did you do, what worked in the end? Thank you!" he says, all in a rush. He resists the urge to cup himself through the cloth of his trousers, as though to demonstrate that he's all back to normal, but doesn't quite manage to stop himself from gesturing somewhat gleefully to his crotch.

"I think, uh. I think I have a bit of a problem," Merlin begins.
