Big Mac's Birthday Bash

Applejack was glad that she had brought towels to their swim tonight. It was pleasantly warm for springtime, but the water was downright cold, and their washing-up session had been brief and full of brisk sputters. They had to work at it a little, but it felt really good to get all of the sweat and dried semen out of their coats. If nothing else, Big Mac had certainly accomplished the coverage aspect of his job.

He flung their damp towels over tree branches and went back to his sister, who had produced a large plastic bottle from her saddlebag. It proved to be an electrolyte sports drink, and she took several large gulps before handing it off to her brother. He chugged the rest of the bottle and made a sound of deep satisfaction. She had figured that he would need to replenish his fluids.

“Well, do you have one more round in you?” teased Applejack, pushing her rump right in her brother’s face. “Just for your little sister?”

Big Mac chuckled. “Eeyup.” He took a couple of playful nips of her flank. She giggled and took off at a trot, heading farther into the orchard.

It seemed an odd time for reflection—what with her horny brother hot on her trail—but Applejack truly loved everything about Sweet Apple Acres. She took a deep breath. It smelled like home. She couldn’t imagine living anywhere else or doing any other job. The one time that she had tried something different—when she went to live with her Aunt and Uncle Orange in Manehattan—had shown her how much she disliked being away from the farm, and the land, and the apple trees.

And of course she had missed her family, but the real reason she returned was the fact that she just couldn’t bear to be separated from her big brother. Upon returning to her home in the country, little Applejack had gotten her cutie mark that very afternoon. And she had given her virginity to Big Mac that very night.

Deep in the apple fields, far away from the farmhouse and the barns, there was a particular, old apple tree that had been around for generations. It was one of—if not the—oldest trees on the farm, and it was the siblings' favorite spot for lovemaking.

Applejack leaned against the tree and waited for her brother. He was just a few seconds behind, and came sauntering up to her. He hadn’t really been worried about losing her—he knew where she was headed.

She approached him slowly and kissed him—a deep, passionate kiss. Nose to nose, she looked him right in the eye.

“If you don’t put that huge cock of yours,” said Applejack calmly, “in my ass, this very minute, then I’ll…then I’ll…” she faltered.

Her brother looked amused and waited to see what sort of threat his sister would come up with.

“Just fuck me already,” she sighed, sticking her butt in the air and flicking her tail in anticipation.

She didn’t have to wait long.

Applejack closed her eyes and felt as her big brother took his position behind her. He slipped his cock into her marehood and gave a few gentle thrusts. The fun and games from earlier had been a blast, but she was glad to have him all to herself for the finale.

Rock-hard and properly lubricated, Big Mac withdrew and rubbed the head of his penis on her butthole, while Applejack concentrated on relaxing her sphincter muscles. It required a team effort to accommodate all sixteen inches of stallion. Several hard bucks later, and her brother was buried up to the hilt. He began slowly—sliding in and out, in and out.

Applejack moaned with pure pleasure. This was how she truly loved to be ravaged by her big brother. On the farm, by themselves, under the stars, beneath the old apple tree. Her sweet brother and his gigantic cock. She felt the earth—solid and fertile—beneath her hooves, and smelled the dirt and the grass and the apples.

Anal was, and always had been, their favorite type of sexual congress, and Applejack—to her friends’ amazement—had never had a problem reaching orgasm. She supposed that when your whole hindquarters were getting pounded like that, it didn’t matter exactly where the penetration occurred.

She just felt so full. Full of love, full of life, full of her brother’s massive pony prick.

Big Mac was grunting with each stroke, and she matched him with sharp howls of her own. They weren’t worried a lick about being overheard. Shoot, they probably made the coyotes a little jealous. She looked up and saw the mare in the moon looking down at them, and wondered how many other ponies were rutting their brains out at that very moment.

Applejack felt her muscles start to clench, and she gritted her teeth as wave after wave of intense pleasure washed over her body. Her mane had fallen in front of her eyes, and she tossed her head with a loud cry of ecstasy. Big Mac gently supported her and caressed her flank while she came.

After a few seconds, she looked back at him and nodded. The stallion started up his hard bucking again, this time with increased fervor. Applejack felt him grip her haunches tightly as he drew in his breath sharply. He thrust again and again, and once more, and then pushed in with all his might, and she felt each warm shot of semen as it spurted deep into her bowels.

Both exhausted, they flopped down on the ground, lying on their sides. Applejack snuggled her back into her brother’s chest, encircled by his strong and gentle hooves. She loved cuddling in the saddles position right after rutting. Her brother’s cock was still inside her.

“So, did you enjoy your birthday gift, Maxie?” inquired Applejack, already pretty sure of the answer.

Big Mac sputtered and murmured his assent into her ear. He kissed her mane and nuzzled her neck.

“I love you so much, Jaxie. My sweet little sister.”

“And I love you. Happy birthday, big brother.”
