(Work-in-progress. Keep watching this space for new chapters!)
After failing to successfully hibernate as her bear friends do, Fluttershy finds herself quite pudgy, and not really averse to being so. Her eating habits before and during her hibernation attempt have also left her with quite the appetite, and who better to purchase good filling food from without having to brave the center of town but the Apple family?
In turn, Applejack finds herself unaccountably attracted to Fluttershy with her new softness, the affection and loyalty of friendship bleeding through into something stronger, heavily spiced with lust. Can she balance her love for her friend with this new craving for her body?
