Big Mac and Granny let it all out
Big Mac knew it was time to let it all out, before plowing her hot granny. "Granny, look, I've seen the ways that you always look at me when I'm wearing those really tight short jeans, and when I'm all wet and sticky from getting peed on by Applejack. And well, It's time I CAME clean, I love you. The way your hot body jiggles, the way your wrinkles...wrinkle..and the smell of fresh horse poop that's always around you...<3" Granny Smith was taken back by this. She had always thought that Applebloom would be the first of the family to want hot sex from their sweet old granny, but here he was, Big Mac, pouring his heart out to her, and precum pouring from his HUGE PENIS. There was no denying it. She loved him back. HOW COULD SHE RESIST!? Granny then goes, while still hoofing herself, " Big Mac, I've always loved you as a grandson..but now..with everything...HANGING OUT...I want something more. I want to have hot apple sex with you. I want you to take me!!"
Big Mac is an early riser
One day, Big Macintosh woke up. He then noticed, that he was very horny, so horny that he already was leaking from his ginormous cock and was throbbing. He then thought to himself, "Boy oh boy am I horny this morning...but why..?" It then hit him like his father used to hit his mother. He was in Love!!! That's right, he knew right then and there that he had a very special somepony. But this was no ordinary pony that he wanted to fuck. Oh no. It was, you guessed it, Granny Smith!!!! He had always loved his family, and his grandmother was no exception. But this love was different. It wasn't the love you would show a relative, but the kind of love that said 'I want to have anal sex with you. now'. And so! He knew that he had to act quickly, before sneaky Applebloom would steal his lover! So he ran down the hall from his love shack of a room, and bucked the door to his grandmother's down with his cock. But to his surprise, he found her granny, but she was naked!! That's right, she was naked. He then saw it all. She had red tits like apples, and her butt cheeks reminded him of apple pies! and she was also rubbing her horsey vagina with her hoof, cus that's what girl horses do, they rub their vaginas with their hooves. Granny Smith was soon close to cumming, when she noticed her very large, hot, and sweaty grandson at her doorway, but he was smiling with a big goofy grin, and she then noticed, that he had a giant black five foot cock hanging from his groin. She squirted a little. "OH Big Mac! What are you doing!? But better yet, what are you going to do...?"
