Big Mac wasn't always like this. Most of the time he kept to himself and his work, and always respected the personal space of his sisters but here he was. Laying next to a sleeping, nude, and thoroughly bred Applejack in the middle and most risky point in her heat cycle. He couldn't even fathom what brought him to do suck unspeakable acts, or the fact that it was his sister who took the more dominate roll in their hormone filled debauchery.

It was deep into the night as Big Mac quietly left the cabin, the wind stirring up around him bringing back the sweet smell of lust that brought him down just a few hours ago. But it was somehow sweeter than before and grew sweeter the farther we got away from the cabin. Approaching the main house Big Mac could see that Apple Bloom's window was wide open, the lights were on, and he could of sworn he could hear some light moaning coming from the open window.

As Big Mac opened the door to the main farm house a new wave of lust washed over him from the floor above, causing his still exposed member to slowly drop to reach his knees once again. As he climbed the stairs the sent grew stronger and stronger as he left another trail of clear fluid behind him. Each step echoed down the hall as Big Mac approached Apple Bloom's room, and each step was accompanied by a desperate moan. It was here were the second act of this family debauchery would take place.

As Big Mac stopped to look at the darkened boarders of the pink door came the desperate moan of his youngest sister. Hearing such passionate cries of lust caused a twitch to run down the length of his spine all the way to the tip of his dangling cock, making it swing and hit the door with a loud thud and leaving a splatter of pre where it touched. As he opened the door the image of his nude little sister was forever burned into his memories, but she wasn't as "Little" as he thought she was. With breasts larger than AJ's and eyes that cried out for comfort, Big Mac realized that his youngest sister had truly come of age.

The door swung shut behind him with a muted "thud" as the two of them made eye contact. There was no screams or yells or shouts of profanity, just the two of them in a lust filled room. As Apple Bloom rose from bed her sweet nectar dripped with with every step she took. As deep shine in her eyes told Big Mac that he had no choice in what was to come. As Big Mac tried to speak Apple Bloom pushed a finger to his lips, shushed him, and went in for a kiss.

An unknown amount of time passed as the two of them locked lips but as the broke apart, Apple Bloom continued to peck at his neck and chest as she slowly worked her way down tell she was on her knees staring directly at he final goal. As Big Mac brought his hands to rest onto his sister's head he thought to himself that he would need to see Zecora later. He wouldn't be able to keep up at this rate with two heat driven sisters.
