Arthur let's out a yelp of shock when his sword disintegrates in his hand and Merlin holds out his hand, channeling his magic to throw Arthur up against the nearest tree. He's winded, but not hurt from the impact and Merlin advances slowly. He stares at the rise and fall of Arthur's broad chest, arms pulled tight above him and Merlin licks his lips.

I still can't decide who would I want to be in this scene. BAMF!Merlin turns me on, but Arthur's just, well, Arthur. :)

Merlin moans agains Arthur's neck and bits down. "I could you know," Merlin gasps out. "I could stretch you with magic and just fuck into you without pause. There's nothing you could do about it—the Once and Future King taking it from his lowly warlock, oh gods, right here out in the open... begging me for it."

*hyperventilates*

And I love your tags. :D
