In the world, there were humans, and then creatures. You and John just so happened to be harpies. You both had similar instincts since you were the same species, so you were both close.

One of those instincts was preening. Since you had large feathered wings, those wings needed to be taken care of. Even though preening was often something done by mates, you and John helped each other. John was currently laying in your lap, his breathing intense as your preen his wings.
