Two weeks.

It's been two weeks, since Winter Wrap Up.

As usual, the early spring work was proving to be intense. Although, it also showed clear signs of being done soon. Aside from their usual chores, the Apple family also needed to prepare the farm for the new year's growth. All the work that the plant team didn't get done during Winter Wrap Up, needed to be done now, before the year progressed any further.

They needed to buck every tree on their land, to clear away any damaged branches. They needed to sheer the sheep's winter coats, so they coud start growing new ones. They needed to fertilize all the crops that were planted during Winter Wrap Up. They needed to clean out the animal pens, and on, and on, and on...

The heavy work load was proving to be a large wear on McIntosh "Big Mac" Apple. The large red stallion sighed, and looked wistfully at the town off in the distance. Normally, he would be fine with such work. Normally, he'd have something else to focus his time on. A hard day of working, or selling some of the food stored over the winter, and he could pack things up, go out to Ponyville, and hang out with his buddies.

Unfortunately, it was that week.

That week, that everypony who wasn't a foal, or married, dreaded. The week that happened every year, when every mare in Equestria would go wild with lust. When they'd try to bed anypony who could understand the concept of sex. It didn't matter how old the pony was, or even if they were male. If you could be talked into following a mare home, you were perfect for the job.

Estrous Week.

Big Mac never went into Ponyville during this week. He didn't find himself to be much to look at. He was big, clumsy, almost never talked, and worst of all, he had a goofy smile. The mares in Ponyville didn't seem to agree with him, though. Not during Estrous Week, anyway. No, according to them, he was dashing, strong, silent, mysterious. He was just perfect for any mare who only wanted a romp in bed.

But Big Mac wasn't the kind for one night stands. He was a romantic. He dreamed of a mare who could stay with him. One who could help out on the farm. A beautiful mare, whom he could have join the family and love her for the rest of his life. He didn't want to "roll in the hay" with some mare who wanted him for his body. His friends might be into that, but he wasn't. Call him old-fashioned, but he couldn't look a mare in the eye, after having shared such an intimate moment; not unless he knew she loved him.

Besides, condoms for a stallion of his "size" were expensive.

And so, he was stuck at the farm. Nothing better to do, than work, and work, and work. He'd read all the books in the house. He'd seen everything there was to see on the farm. He'd even tried striking up a conversation with the cows, but they only ever talked about grazing and bulls. The only thing that helped ease the monotony was Applejack's quick wit.

Big Mac smiled, as he thought of his sister, making his way over to the storage barn. She wasn't much for boasting, but that mare had a sharp tongue. She could also spin one hay of a tale, and she certainly didn't have a shortage on stories to tell. Out of idle curiosity, he'd once asked her what it was like to go through Estrous.

"Long as I can keep away from any other mares, and focus on my work, I can keep it under control for the first few days. Once it starts gettin' worse... Well, I've got other means to keep myself in check."

When he'd asked her what those means were, she blushed, and said,

"Uh, well... I-if it ever gets too bad, I just... Take a leap into the pond! It's still cold from winter, so the shock really clears my head!"

Her eyes then flicked back and forth, like they always do whenever she just makes up a lie on the spot. Big Mac never pressured her into telling the truth, though. It was clear to him that it was an embarrassing subject for her to talk about, and he loved his sister too much to make her feel uncomfortable on purpose.

Unless it was funny, like whenever he would bring up baby stories to her friends. Her face would go beet red, and she'd glare at him with the intensity of the sun.

McIntosh's thoughts cleared when he noticed that he'd made it to the barn. He sighed a tired sigh, and opened the door. Light fell upon the various farming equipment they'd stored inside for the winter. He planned to sort through them, and get everything ready for the impending plow.

Unfortunately for his plans, his body was starting to feel heavy.

He'd felt this before, usually on years like this; when the chores were hard, and Estrous Week was in full swing, and he'd work without end. He'd get so fatigued that he'd simply need to lie down wherever he was, and sleep for an hour or two.

The fatigue was weighing down on him, hard. But he couldn't just lay down here. The ground was packed dirt, and there were metal tools everywhere. He thought longingly of his soft bed, but that was all the way back in the house, and he wasn't sure if he could drag himself that far. Besides, AJ would kill him if she knew he'd taken a nap when he should have been working.

Then he remembered the loft.

It was positioned directly above the doors to the barn. Most ponies didn't even notice it, when they first entered. It would make the perfect hiding spot. It was full of hay that would make a comfortable bed, and best of all, it was right here. He wouldn't have to do much work to get to it.

Big Mac closed the barn door, causing the small amount of light to diminish. The only illumination came from the cracks between the boards, perfect lighting to nap in. He made his way over to the ladder that connected to the second level, just off to the left of the door. He'd always hated climbing ladders, his bulky frame just wasn't suited for it. He'd do it though, if it meant that he could sleep in peace.

He shifted his weight onto his back hooves, and lifted his front ones up to the rung directly in front of him. He wrapped his hooves around the rung, and heaved his massive body upward. He swung his back hooves onto the bottom rung, and moved his front hooves up a rung. With a grunt, he lifted himself up again, getting closer to his goal. He repeated his awkward dance until he finally reached the top of the ladder. With a groan, he rolled onto the floor of the loft and closed his eyes, panting.

He could definitely just sleep here. The fatigue was growing, and that exertion hadn't helped at all. He opened his eyes and gazed longingly at a pile of hay. It was only a foot or so away. He'd definitely be harder to spot over there, and it would most certainly be more comfortable.

He snorted, and lifted himself off the loft floor. He shuffled over to the hay, and began flattening out a portion of it. When he'd made a nice sized nest to sleep on, he flopped down, and closed his eyes.

He'd earned this nap.

...~~~***xXOXx***~~~...

Woof! Woof!

Big Mac's rest was interrupted, by the familiar barking of the family's dog, Winona. He knitted his brow and rolled over, content to return to his slumber.

"Hush, girl! We don't want anypony noticin' us!"

Big Mac's eyes shot open, at Applejack's voice. She must have come to check on how well the tool sorting was going. She was going to give him one hay of a lecture, if she found out that he'd been sleeping, instead of working.

He clenched his eyes, and brought his hooves together in front of his muzzle.

"Please, Celestia, let her just be passin' by. Don't have her open the barn door," he prayed, fervently.

The barn door creaked open, letting a broad stream of light spill onto the floor.

Immediately, Winona bounded in. She started sniffing around the barn, pausing every now and then, to inspect some scent she’d found. With the sound of hooves, an orange mare entered Big Mac's field of view. The trademark hat, sitting upon golden locks of hair, gave the mare away as Applejack. She took a long, sweeping look at the barn’s interior.

She snorted, “He ain’t even started sortin' the tools. I’ll bet he’s off nappin', under some tree,” she said, shaking her head, and walking further into the barn, “ I swear, that stallion is useless without me.”

“Please, Celestia, let that be it. Let her leave to find me in the orchard,” Big Mac prayed.

Applejack sighed, and closed the barn door behind her. Darkness enveloped the barn again, but Big Mac's eyes were already adjusted to it.

“S'pose that’s good. I didn't want to have to ask him to leave,” She said to Winona.

The dog had started sniffing at the base of the ladder, having evidently found some scent she found interesting. She reared up onto a bottom rung and barked excitedly into the loft.

“Please, Celestia, don’t let AJ look up here,” Big Mac prayed, with desperation.

“What’cha find, girl? Is there a raccoon up there?” AJ asked, shifting her own gaze up to the loft.

“Please, Luna, don’t let AJ find me,” Big Mac prayed, having lost a lot of his faith in the Sun Princess.

Applejack’s eyes scanned the loft. Big Mac could practically feel her gaze scan over his prone body. After a few tense moments, Applejack looked back down at the excited dog with her.

“There’s nothin’ up there, sugar cube. You’re barkin’ at ghosts,” She said.

McIntosh let out a silent sigh of relief. “Thank you, Luna,” He thought.

He watched, as his sister turned back into the barn. “Come on, girl,” She said, to Winona, “You know what we’re here for.”

Now Big Mac was interested. What had she come to the tool barn for, that he couldn’t be present for? Now that he thought about it, he could certainly remember a few instances when AJ had convinced him to leave the barn, in favor of doing some other chore. Usually something that AJ said she couldn’t handle herself.

He watched with bated breath, as Applejack laid down on her belly. His eyes widened, as he saw her tail move upward. His breath caught, when her tail completely flagged itself. He stared, as his sister’s vagina was displayed fully, glistening with moisture and winking with want.

The mare looked back at the dog, who was waiting patiently. AJ lidded her eyes, and huskily said, “Come on, Winona, you know what to do.”

Winona moved over to her mistress's twitching mound and began sniffing. Applejack hummed in approval. The dog’s tongue flicked out, briefly touching Applejack’s engorged marehood. The mare bit her lip, and let out a breath of pleasure. Winona dove in more enthusiastically, lapping at her master's swollen pussy.

“That’s it, girl,” Applejack whispered.

Winona pressed her snout deeper into Applejack’s wet cunny, earning a quiet groan from the mare. AJ closed her eyes, an shifted her hooves into a more comfortable position. Winona began licking at Applejack’s vagina more fervently, and the latter shuddered with delight. She licked her lips, and moved her hips to get Winona’s tongue to slide over her sensitive spots.

“G-good doggy,” Applejack stuttered.

Meanwhile, in the loft, Big Mac lay in stunned silence. He watched, as Winona pleasured his sister, right in front of him. A certain part of his anatomy had made itself known quite some time ago. How could he not react to the lewd scene? Let alone the incredible smell his sister was producing in the enclosed space? The new detail, was his hoof idly pawing at his hot member.

It was more of a reflex, than anything else. The hoof had just started moving on it’s own. When he noticed what he was doing, he jerked his hoof back; as if he were touching a burning hot metal rod, rather than his own penis. It wasn’t right to do that sort of thing with his sister in mind.

A groan forced his eyes back onto Applejack, below. She had begun slowly humping her hips up and down, to the rhythms of Winona’s licking. The dog had apparently grown tired of Applejack’s vagina, as she shifted her tongue upward, onto the mare’s anus. AJ let out a loud moan, and she threw her head back.

“Oh, Celestia, yes! Good girl, Winona!”

...Well, what Applejack doesn’t know won’t hurt her. Big Mac’s hoof found it’s way back to his engorged member, and he began sliding it up and down his length.

Applejack’s hips began moving more sporadically, humping up and down wildly. She pressed her face into her front hooves, trying to muffle the sounds of pleasure escaping from her. Her hat fell off, as a result. Winona kept working on AJ’s puckered asshole, pressing her snout hard into the mare’s backside.

A muffled “Ooooooohh!” emanated from the quivering mare, and she started grinding her hips into the dog’s versatile tongue. Big Mac had begun working more on the ridge in the center of his shaft, as his orgasm neared.

“Wait, Winona!” AJ groaned, “I want to change positions.”

The dog hesitated for a moment, but quickly complied, sitting back onto her haunches. Apparently, she'd been well trained for this activity. Applejack rolled onto her back, lifting her hind legs into the air. Big Mac nearly lost it then. His sister’s... bits were on full display. He had an even better view than before, even being allowed the privilege of seeing AJ’s gorgeously erotic looking teats. He placed his other hoof onto his cock, moving them both in tandem.

“Okay, girl. Get back at it, I was so close,” the mare whimpered.

Winona got back up, and dove in again, attacking the top of Applejack’s winking sex. AJ whined in ecstasy. She arched her back and let her tongue loll out of her mouth, panting loudly and erratically. Her face and neck were the color of red delicious apples. Big Mac was in no better shape. His orgasm was so close he could see it. The tip of his cock was flaring, and the pressure in the head was building.

Winona gave a long, deep lick to the entire length of Applejack’s pulsing vagina. That was it, Applejack let loose a scream, as her entire body convulsed, over and over. A thick, musky, translucent yellow fluid poured from her pussy like water from a faucet, and she threw her head back, lost in the ecstasy of her orgasm. With the dirty lewdness of seeing his sister in such a way, Big Mac could no longer hold back. He bit his lip to remain silent, and flew over the edge.

Thick rivulets of cum burst from his cock, spraying into the hay next to him. Over and over, he shot his seed into the straw, humping his hips into his hooves all the while. He couldn’t help but let out a quiet grunt, as he let out his jizz.

Both siblings panted with exhaustion, simply lying where they had fallen, basking in the afterglow. Winona idly licked at her master’s groin, trying to clean the last of the sweet fluid from her inflamed sex. Applejack twitched occasionally from the sensitive flesh's stimulation.

After a few moments had passed, Applejack rolled back onto her belly. She picked up her fallen hat, and placed it back on her head. She struggled up onto her hooves, and looked at the door to the barn.

“Come on, girl,” she said, “let’s see if we can’t go find Big Mac. He’s in for one hay of a lecture, if I can find him sleepin’, instead o' workin’.”

The mare shuffled over to the barn door, her pace slightly hitched, and pushed it open. She let Winona go first, before following, and closing the door behind them.

Big Mac merely laid there, feeling guilt set in. He had just watched his sister go through one of the most private experiences anypony could go through. His baby sister, whom he'd known since her birth; and he had gotten off to the sight of her desperation. He was sick. No stallion should ever do something like that.

He sighed, and pulled himself to his hooves. He shuffled over to the ladder, and climbed back down.

“Might as well get back to work,” he mumbled to himself.

He slumped over to the door, and opened it up, letting the light into the barn, so he could see the tools he was supposed to sort.

Things were going to be more complicated between him and his sister, and she wouldn’t even know why.
