<blockquote>Arthur is just a boy when he realises that he gets excited from bridling his horse. When he's older, he steals a bridle and uses it to pleasure himself. One day, Merlin finds the bridle and offers to help him. As their mutual play develops, Arthur becomes Pony, Merlin's horse, and Merlin becomes his groom. Together they learn about love, responsibility and the value of service.</blockquote>

<blockquote>[Note: THIS IS THE BEST PONYPLAY STORY YOU WILL EVER READ. VERY POSSIBLY MY FAVORITE MERLIN STORY EVER. I AM NOT KIDDING.]</blockquote>
