Big Mac, and his sister, Applejack, were as close as siblings could be, and yet there were even closer at one point or another. But that was in the past, as the stallion has married the beautiful unicorn, Sugar Belle. Living at Sweet Apple Acres, Sugar and Mac are in a happy marriage, but a rather dry spell of one. As well as this, his sister had been repeatedly trying to seduce him. Holding strong, the stallion believed eventually, Applejack would give up; he was wrong.
