This story has a pony in a diaper, and consists of a fetish know as being an 'Adult Baby'. If this doesn't appeal to you, I warn you to turn back, but also ask you don't write this off too quickly.

One fine day, while working in the orchards of Appleoosa, Braeburn is approached by a very dear friend, Little Strongheart, as she returns for her tribe's annual run. After a day of working himself to the bone, accepting a little help in exchange for teaching her a thing or two about taking care of foals seems like an easy peasy trade. Little does he expect, the kind of Strongheart needs in hoof-on experience, and Braeburn is perfect to be practiced on.
