Merlin is so lovely it hurts. Huge, silly ears. Dark hair drying into faun-like curls. Miles and miles of legs in soft grey school trousers. His shirt is thin and white, and Arthur knows he's not wearing anything underneath, because his nipples are visible through the fabric.
Written for this KMM prompt: Arthur/Merlin modern AU Arthur (in his late twenties) has a secret kink he is terribly ashamed of: He has this thing for schoolboys, but would never dare to act on it. Then he falls in love with Merlin, who is 21/22 or something but looks 17/18. Merlin finds out about Arthur's kink and dresses up as a schoolboy, making himself look even younger. Then he surprises Arthur.
