Big Macintosh's persona as the kind, caring, stallion of few words has earned him a reputation of honesty and trust. But underneath this calm smile is a stallion who just wants to fuck. Problem is, the heat waves have begun and the last thing he wants is to father more foals. By happenstance, he comes across his sister, Apple Bloom, who is also going through her heat. It's then, he finds a middle ground. Certain fillies can be old enough to learn to handle him, but young enough to not get pregnant.
