Big Mac Sodomizes...

Big Mac was pulling his plow across the field. He was working up a real sweat because it was a hot sunny day with a lot of birds singing in the trees, and the sounds of crickets in the tall grassy areas that surrounded where he was. He stopped for a moment and took his collar off after removing the harness that connected him with the plow and wiped the sweat from his brow. Something about working the land and reaping the benefits of nature made him feel content and happy. Perhaps it was his earth pony nature, but whatever the case he always felt at peace when he was out in the field. He almost wished that he didn't need to stop working, but then again there were other things that he needed to do.

"Hiya, Maccy!" a voice shouted.

Not expecting the sudden outburst, Big Mac stumbled backwards and fell upon his rear. He sighed in relief when he noticed the pink bubble of excitability and stood up dusting himself off. It was none other than the hyperactive mare, Pinkie Pie.

"Workin' hard?" she asked.

"Eeyup."

"You like working hard?"

"Eeyup."

Pinkie folded her forehooves over her chest and stroked her chin as if coming to a conclusion of some kind. "I see. How come?"

Big Mac shrugged. He really couldn't put it into words.

"You know, I like working hard too! But I make parties, so my working hard is when I party hard," Pinkie smiled. "Do you like parties too?"

"Eeyup."

"Do you like rutting?"

Big Mac paused. Perhaps he hadn't heard that question right. He turned to the pink mare who was looking at him expectantly, but he couldn't process what he had just heard. He was about to ask her to repeat herself when she can him off.

"So, do ya?"

Guess she did ask what he thought she asked.

"Eeyup."

"Great! Well, I was wondering if you could do be a huge, big favor."

"Eeyup."

"That would be really be helpful for me! Thanks Macky." Pinkie grinned and turned around and swung her tail to the side. "I need you to plunge your steaming hot cock deep into my body."

Big Mac blinked. He then blinked again. Then a third time. He saw Pinkie's balloon knot and felt something stir under him.

"You don't want to?" Pinkie asked, tears forming in her eyes.

The red stallion leaned back and showed his huge erection to Pinkie, signifying very much that he wanted to plunge his penis into her body. The mare's eyes widened as she stared at the magnificent staff from tip to balls. Despite seeing many a penis in her time, there was something simply majestic about the incredible girth and majesty of the phallus in front of her.

Pinkie squealed in joy and then wiped the drool from the corner of her mouth. "I want it up my plot! Do you want to put it there?"

"Eeyup."

"Great! I have lube!" Pinkie said, reaching into her hair and pulling it out. "Apply liberally and go at it. Rut me like you've never rutted any pony before!"

"Eeyup."

Big Mac aimed his penis and drove it home. Pinkie pushed back on that cock trying to fit his entire length in, but found that she couldn't. Did that stop her? No. She pushed harder and harder, Big Mac allowing her to attempt the impossible. But as she pushed deeper, the muscles within and throughout her body massaged his throbbing member and he found himself being pushed to the brink. Then, suddenly, Pinkie let out a gasp as she felt herself being inflated by the massive amounts of seamen spurting deep into her abdomen.

"Ooh. Fill me up like jelly doughnut!" Pinkie cooed.

"Eeyup," Big Mac gasped as he pushed the last few squirts into the pink mare.

Pinkie waited for a bit until the cock shrunk down falling out of her ass with a 'pop'. She smiled and kissed Big Mac on the cheek. "Thanks, Macky. Let's do this again soon!"

"Eeyup," sighed contentedly as he sagged down near his plow.

With that, Pinkie left a very happy, very plump, mare. Mac saw his semen drip from the cut little plothole, squirting out a tiny bit each time the mare bounced away.
