It had been about a couple months since your full transformation into an actual horses asshole, well as far as you're aware of. And for the first week you couldn't really completely convince yourself of the situation you were in, well until the horse excreted it's waste out of you. You became use to it after a while, though you could still taste the shit leave your mouth, but somehow when you transformed into an anus the settings transferred the feature of comfort as you seem to adjust to the taste as if you were an asshole your whole life. The turds were salty, yet sweet like nectar after the droppings left your mouth.
As far as right now you seem to understand the small mannerisms and dealings that your horse does every day. In the morning from what you can tell, since you can't see through his tail hairs very well, he grazes and releases his morning load like most days. Where this is where you come in, and you seem to look forward to it every time. From the moment where the droppings touch your lips, to it leaving your pucker and landing on the grass. There was something oddly comforting to watch the turds on the ground, like if it were your children. Then again you haven't talked to anyone descent for months so your mind wanders from time to time.
Your horse, who you seem to call Harold, doesn't really have a mate to have a go with. So everyday is mostly just 95 percent grazing and sometimes your horse's owner has a ride with him. You also seem to befriend his tail, as it always swats the flies away from your vulnerable pucker. The days are relaxing as you have no way of movie any muscle in your body and your horse does everything for you. Admittedly so you seem more content with this life than your last one, and you were more happier. Though the only thing was how lonely the days was without anyone to talk to. Anyways you would trade this life with anything else except to be this beautiful stallion's butt.
