Applejack (finished)

Applejack, never one to beat around the bush, had explained it all to you quite succinctly. Earth ponies had special ties to the land, and the ability to greatly and rapidly encourage growth. This came from the race's abundant supply of innate life magic - not a discipline they could practice consciously like a unicorn, but a very much present and very much powerful one nonetheless. They gave this energy off continuously in small amounts as they went about their daily routines, and earth pony farms prospered like none other as a result. But the process was a slow one, frustratingly so at times. In bad times such as flash floods or insect swarms, what the trees really needed in order to keep going was a huge, sudden influx of this magic, to buffer them from whatever the threat was. As a general rule, this couldn't be done. With one exception.

Life energy responds to life energy, and there were few acts so strongly associated with the creation of life as procreation. Sex provoked a huge response from an earth pony's magic, saturating the entire nearby area with this renewing energy as life encouraged life. Getting knocked up constantly was not exactly a practical way to run a farm. But being a human, you might just be able to get Applejack 'producing,' without the risk of getting her pregnant. Which raised all sorts of possibilities in the pragmatic working mare's mind.

You eagerly took hold of Applejack's flanks, feeling the firm muscles ripple slightly under your kneeding fingers as you enter her for the first time. Her pussy felt... welcoming, in a way that was hard to qualify, and both of you sigh in contentment as you hilt yourself in her marehood. You bend down as she leans up, your lips meeting as your tongues dance about each other slowly. Something about fucking AJ just feels profoundly right, like you were always meant to do this; you're in no hurry to finish. You enjoy every deep, steady thrust as Applejack responds with equal enthusiasm. For a long time, the only sounds in this part of the orchard are the wet slaps of sex meeting sex, interspersed with the occassional noisy kiss or moan.

Some time later, Applejack closes her eyes and smiles deeply, a warm glowing suffusing her mind as you hilt yourself with a groan. Right on cue, she feels your warm cum pumping into her, her own orgasm milking you for every drop. Satisfied, she presses back against you, trying to make sure you get as much inside her as possible. Eventually you pull out, laying down heavily on the grass and breathing deeply. Applejack lets you rest. She has no idea if this will work with a human or not, but she has three more fields planned for this afternoon. In either case, it's going to be a very fulfilling day.
