Big Macintosh becomes a polygamist with Rarity, Cheerilee and Fluttershy as his three wives.

Commanded by Celestia, Big Mac becomes a polygamist. Rarity, Cheerilee and Fluttershy are selected to be his three wives.

I'm really surprised I haven't seen more of these types of stories on here. With the ratio of female to male characters, this universe lends itself to clopfics about polygamy pretty well. If anyone out there is inspired by this fanfic to draw some artwork with Big Mac as Bill Paxton, circa 'Big Love' surrounded by his three wives, I'd totally use it as the graphic for this story.
Warning: Contains clop.

Please leave comments telling me what you think of the story. I love feedback! Also, feel free to check out my other stories and thanks for reading!.

Big Mac's Third Wife

Big Macintosh was a humble apple farmer. He never sought for notoriety. He was content to buck apples with his sisters on Sweet Apple Acres, but even Big Mac knew that one does not simply refuse a commandment from Celestia.

“But why you, for pony's sake?” Applejack asked as she and her brother carted apple to their barn.
“I couldn't say,” Big Mac replied, “I just know you don't question an order from the Princess.”

“But nopony has been commanded to practice polygamy for generations,” Applejack said, “I'm worried 'bout what folks'll say.”

“Whatcha all gonna' be practicin,' big brother?” Apple Bloom asked as she skipped beside her siblings.

“Polygamous marriage,” Big Mac said, matter-of-factly.

“What's polygonal marriage?” Apple Bloom asked, clearly confused.

“It means your brother's gonna' be takin' more than one wife,” Applejack said, a note of disapproval in her voice.

“Ya'll mean yer gonna' have several special someponies?!” Apple Bloom asked excitedly, “How come you can do that? I thought you couldn't have more than one special somepony.”

“It's the will of Celestia that I have several mares,” Big Mac said, somberly.

The three Apple siblings continued to move towards their barn, as the afternoon sun started to set in the west. Over the hill, Apple Bloom's two friends came roaring up on Scootaloo's scooter.

“Hey, Apple Bloom!” Scootaloo and Sweetie Belle said, “What's goin' on?”

“Big Mac's telling me all about polygonal marriage!” Apple Bloom said, excitedly.

“What's that?” Sweetie Belle asked.

“Ya'll remember your scripture stories?” Big Mac asked, “You remember reading about the Prophet Moseys who parted the Red Sea?”

“Yeah,” Apple Bloom said, “Twist's parents taught me all about him last year when she invited me over for Ha-neigh-kah dinner.”

“Well what most ponies don't know is, Moseys was also commanded to practice plural marriage,” Big Mac said, “The Prophet A-bray-ham also had multiple wives. Over the centuries, Celestia has commanded certain stallions to be polygamists.”

“Gosh, Big Mac,” Sweetie Belle said, impressed, “Does that mean you're a Prophet of Celestia, too?”

“Nope,” Big Mac said humbly, “I'm just a simple work horse who's been given a new task to perform.”

“Hey!” Scootaloo said, “What if being polygonalist is our special talent?”
“The three of us could all share one special somepony!” Apple Bloom said, getting excited.
“Cutie Mark Crusaders Polygonal Wives, Yah!” the CMC cheered.

“Now hold your horseshoes,” Applejack said, “Ya'll three can't go getting' hitched to the same colt, jus' 'cause ya' feel like it.”
“Aww,” the CMC said, looking crestfallen.
“Eeyup,” Big Mac said, “You'd need Celestia to command you to do it.”

“So who are your wives gonna' be?” Apple Bloom asked.
“Don't know,” Big Mac replied, “I'm gonna' just have to wait and see.”

Several months had gone by, and a lot had changed on Sweet Apple Acres. Three new homes had been built next to each other, on what was once a vacant field beside the Apple family barn. These cottages housed Big Mac's three wives.

From left to right there was a newly-built yellow house with a butterfly painted above the door, a purple house with a flower over the door, and a white house with a diamond above the door.

Rarity was helping Fluttershy unpack her things.
“I'm so nervous,” Fluttershy said, as she stacked her boxes of animal food, “I can't believe Celestia chose me to be one of Big Mac's wives.”
“You'll adjust dear,” Rarity said, “I remember when Cheerilee arrived. It felt like I was being replaced. As time went on though, she and I became the best of friends. It will be even easier with you, Fluttershy, because we're already best friends!” Rarity leaned in to give Fluttershy a hug.

Fluttershy whimpered.
“Darling, what's wrong?” Rarity asked, pulling away from the hug.
“It's just,” Fluttershy said, “I've never been with a stallion before. It Big Mac...nice?”
“You want to know if our husband's a gentle lover?” Rarity asked, smiling, “Let's just say Big Mac excels at being...subservient to your needs.”

Once school had let out for the day, Cheerilee headed home to her little cottage on the farm. Rarity and Fluttershy had just finished getting the new house in order, when Cheerilee walked inside.

“This place looks great!” the purple mare said as she surveyed Fluttershy's newly-furnished cottage.
“How was school?” Rarity asked.
“Oh, the children were wonderful,” Cheerilee said, “Sweetie Belle says hello, by the way.”

Fluttershy sat and listened. Not having any school-aged children in her life, the yellow mare never had much of a reason to get to know the school teacher better. Now she was sitting here with Cheerilee, a stranger. The pegasus felt her usual shy self. Fluttershy suddenly felt very grateful that one of Big Mac's wives was Rarity. At least the yellow mare already had somepony here she knew well.

“So Fluttershy,” Cheerilee asked, “What is it that you do?”
“Oh,” the yellow mare said, blushing, “I...uh...take...um...”
She was embarassed. Compared to Cheerilee's profession as a teacher, her job of grooming animals seemed unimportant. Sensing her friend's shyness, Rarity stepped in.

“Fluttershy is excellent with animals,” the unicorn said.
“An animal expert is certain to come in handy on a farm,” Cheerilee added, beaming. Fluttershy smiled.

“I can see why we were all chosen,” Cheerilee continued, “With my teaching abilities, I'll be able to instruct the fillies and colts Big Mac will give us. Rarity's love of fashion and attention to detail will help keep the farm looking beautiful. And Fluttershy can care for the animals, while being a wonderful, nurturing mother at the same time.”

The three mares then went next door and set to work preparing dinner in anticipation of their husband's return.
"Cheerilee, check the temperature on the stove!" Rarity said as she filled cups by levitating a pitcher, "Fluttershy, lay out the table settings!" The white unicorn was barking orders like a drill sergeant.
"Rarity's so organized," Fluttershy thought as she tried folding the napkins, "She's always willing to take control."
Cheerilee saw that Fluttershy was struggling with her job, so she came over to help.
"Watch me, Fluttershy, and do what I do," the purple pony said, "This will make setting the table easier."
"Cheerilee's such a good teacher," Futtershy thought, smiling, "She lowers herself to raise other ponies up."
"Thank you," Fluttershy said timidly.
"Happy to help," Cheerilee said, "As wives, we need to be there for each other."
While the three mares set about completing their tasks, Fluttershy started to feel better about this whole situation.
"Maybe being one of Big Mac's wives won't be so bad," Fluttershy thought.

Sweat dripped down Big Mac's brow as the work horse returned after a long day of applebucking. As he approached the cottages, the lights were on in Cheerilee's home and Big Mac saw three mares milling about; making last minute preparations.

The red stallion smiled. He was ready to eat.

Dinner for Four

When their husband entered the purple cottage, Rarity and Cheerilee were there to greet him with a kiss on each cheek. Fluttershy blushed, watching all this happen as she stood in the kitchen doorway. She felt more comfortable around the other wives, but the yellow mare was still nervous around Big Mac.

“Let me get your yoke,” Cheerilee said as she removed the harness from around Big Mac's neck.
“Are you ready to start dinner?” Rarity asked.
“Eeyup,” Big Mac replied.

The stallion was about to take his place at the table, when he saw Fluttershy trying to hide herself in the kitchen. The pegasus had hoped that if she didn't say anything, everypony else would forget she was there and start eating without her.
Big Mac calmly appoached the trembling mare.
“I'm so happy you've joined our family,” Big Mac said.
Fluttershy let out a scared squeak.
“Come sit with us at the table for dinner,” Big Mac said, extending a hoof to the trembling pegasus.
“Okay.” Fluttershy said in a throaty whisper.

The four ponies gathered around a square table. Fluttershy sat across from Big Mac. Cheerilee was on his left, and Rarity sat to his right. Before them sat a large alfalfa casserole.
"This looks delicious!" Big Mac said loudly.
"We all worked together," Cheerilee said.
"Fluttershy set the table," Rarity added.
"Looks great," Big Mac said, giving Fluttershy a wink.
The pegasus blushed and flashed him a timid smile.

“Well, let's get started,” Big Mac said, “Bow your heads. Let us pray.”

“Dear Celestia,” Big Mac began, “We thank you for the (ooh!)”
Fluttershy opened one eye. She looked at Big Mac, who's face had contorted. His eyes were clenched shut. It looked like he was struggling to finish the prayer.

What Fluttershy couldn't see, was that under the table, Rarity and Cheerilee were each rubbing one of their hind legs along big Mac's stallionhood.

“Oh Celestia,” Big Mac, moaned, trying hard to focus on the prayer, in spite of the stimulation his loins were receiving, “we thank you for the sunrise.”
“That's not all that's rising,” Rarity thought as her hoof stroked her husband's swelling member.
“And we thank you for the hard wood...(ooh)” Big Mac said, forgetting himself for a moment, “Apple trees! We thank you for the hard wood apple trees!”
“Nice recovery,” Cheerilee thought, grinning, “Let's see how long you can last.”

Fluttershy jumped when she heard a thump sound during the prayer. It caused the water in the glasses to ripple. Unbeknownst to her, the sound was caused by Big Mac's erect cock hitting against the underside of the dinner table.
Precum got on Cheerilee's hind hoof as she massaged Big Mac's cock head.

“And please bless this food,” Big Mac said, sweating, “That it will help us grow big and strong.”
“You don't need any help there, stud,” Rarity thought as she pressed her hind hoof against Big Mac's blood-engorged meat stick.

“In Luna's name, Amen.” Big Mac said, through clenched teeth. The stallion then let out a gasp; amazed at his levels of self control.

“Amen,” his three wives echoed. Fluttershy had never heard such an eccentric prayer before in her life.
Rarity and Cheerilee pulled their legs away from Big Mac's twitching dick. The purple mare rubbed her hoof against the ground, trying to wipe off her husband's lube. The stallion glared at his first two wives, clearly a little put out at them for disrupting the blessing by giving him a hoof job. The two offending mares returned the stern looks with coy smiles.

Big Mac's cock remained hard all through dinner. The pain was excruciating. He desperately needed release.
“I think it's about time for dessert,” Cheerilee said, once plates had been cleared of casserole.
“Yes! Dessert!” Big Mac said, a little too eagerly, “Bring out dessert!”
“Fluttershy, darling,” Rarity said, “Would you come join us in the kitchen?”
Fluttershy excused herself and went to join Big Mac's other wives.

Soon the three mares came out with three small chocolate bundt cakes. Rarity directed the other mares to sit down to the left of Big Mac. From left to right it was Cheerilee, Fluttershy and Rarity. The first two wives held their cakes in their forehooves, raising them up to where they were just under their chins. Fluttershy saw this and imitated them.

“Big Mac loves my bundt cakes,” Cheeilee said, proudly.
"Oh baby," Big Mac said, drooling, "I could eat your bundt all day long."
"I'll bet you could," Cheerilee flirted back, giving her husband a sly wink.

“But darling,” Rarity said in a stilted delivery, “Where's the icing drizzle? It's just not your famous chocolate bundt cake without the icing drizzle!”
“Fluttershy,” Cheerilee said mischievously, “ask our husband if he could provide some icing for our cakes.”

Fluttershy had no idea what was going on, but she played along.
“Um, Big Mac,” Fluttershy said timidly, “can...can we please have some of your icing?”

During the whole bundt cake conversation, Big Mac had been staring at his wives as he stroked his meat. Hearing the magic words from Fluttershy, the hard stallion stood up from the table. The timid pegasus gasped when she saw Big Mac's mammoth tool. Their husband's cock was pointed directly at them.

“Here's your icing, ladies!” Big Mac said with a grunt as he proceeded to blow his load all over his three wives.
Fluttershy let out a shriek when she realized what was happening, and tried to shield herself with her bundt cake.
Rarity and Cheerilee on the other hand, leaned their heads forward with their mouths open wide, hoping to get as much of Big Mac's icing onto their tongues as possible.
Ropes of cum landed across the three mares. Even with Fluttershy cowering behind the cake, stallion splooge still managed to get in her pink mane.

Cheerilee and Rarity giggled like drunken college fillies as the last spurts from Big Mac's balls shot down their throats.
"You make the tastiest, salty treats, Big Mac," Cheerilee said, cum dripping down her nose.
Setting their jizz-drizzled cakes down, Rarity and Cheerilee turned to each other and started making out; licking their husband's cum off of each others faces.

Fluttershy trembled, still holding her cum-covered cake over her face. Big Mac took it from her and set it on the ground gently. Then, lifting up the confused pegasus, the spent stallion gave her a big kiss on the lips. Breaking the kiss, Big Mac looked into her eyes.
“I love you Fluttershy,” he said. She stared back at her husband blushing; shaking like a leaf, as his cum oozed down her mane and partially dangled in front of her nose. The yellow mare didn't know what to think. She just stood there, unable to form her feelings into words.

Once Rarity and Cheerilee had successfully cleaned each others faces, they looked down at the spunk-speckled chocolate bundt cakes.
“You know,” Rarity said, “I'm not in the mood for cake right now. I filled up on too much icing.”
“Same here,” Cheerilee said, running her tongue around her lips to catch any trace amounts of her husband's seed, “The icing should keep if we leave the cakes in the fridge overnight. I'll take one with me to school tomorrow and eat it during lunch.”

Having finishing processing what she just saw, Fluttershy had some questions. Having never been married before, the pegasus just assumed that this was something married people did. That excuse didn't make the experience seem any less gross, though.

“How often do you do this?” Fluttershy asked, dreading the answer.

“What, the cake thing?” Rarity asked, "I suppose never having been with a stallion before, this whole thing must have seemed shocking. Don't fret though, this was just a one-time-only special performance."
“I hope you liked it,” Cheerilee said, “Think of it as a special 'welcome to the marriage event' we did just for you.”
“Um...thanks?” Fluttershy said, uneasily.

“Now if you're wondering about the typical nightly schedule,” Rarity said, pulling out a chart, “Today's Wednesday; Big Mac's conjugal day of rest.”
“Eeyup,” Big Mac said.
“Right,” Cheerilee added, “No humping on Hump Day.”

“Cheerilee and I used to alternate our nights with Big Mac,” Rarity said to Fluttershy, “But now that you've joined us, we've added you to the rotation!”

Under the Thursday for that week there was a big red 'F' that was circled. Friday had a similar red 'C' and Saturday had a red 'R'.

“Oh...my” the yellow mare said, apprehensively.

"And Fluttershy's never been with a stallion before," Rarity said to her sweaty husband, "So you'll be the first to break her in."
Fluttershy squeaked. Big Mac looked at her, snorted his nostrils, then smiled and gave her a wink.

After dinner was over, the four ponies went to their respective homes. On Wednesdays, Big Mac slept in his old bed in the Apple family home. The other six nights of the week, he was guaranteed a warm bed to sleep in.

Fluttershy went home and took a long bath, scrubbing her hair clean of jizz. As she sat in the warm water, she thought about her husband's hot, throbbing cock, and lazily began teasing her pussy.
"I wonder how it will feel," she thought. Fluttershy suddenly became very still. She realized that this would be her last night as a virgin.

Sticky Icing

“I don't know,” Apple Bloom said, “Are you sure it's okay for us to have some of Cheerilee's chocolate cake?”
“She wouldn't have left it out if she didn't want us to have it.” Scootaloo said.
“Left it out?” Sweetie Belle said, incredulously, “It was covered up under her desk until you pulled it out.”
“In any case,” Scootaloo said, dismissively, “you and Apple Bloom are her family now. I'm sure Cheerilee wouldn't mind sharing some of her cake with family and their pegasus friend.” The orange filly gave a big toothy grin.
“That icing drizzle does look pretty good,” Apple Bloom said, licking her lips.
“Augh! Fine” Sweetie Belle said, caving in to peer pressure, “But just one slice.”

The CMC cut off one large slice to share.
The icing stretched as the slice became separated from the rest of the cake.
“I've never seen icing this gooey before.” Scootaloo said.
“”I bet it tastes great,” Apple Bloom said, her mouth watering.

Setting the big slice of cake on the back of a notebook, the CMC ran to a quiet corner of the playground to enjoy their sweet treat. Their young mouths watered as they stared at the moist chocolate cake, dripping with gooey frosting.
Sweetie Belle moved in and took a sniff.
"Is it just me, or does this cake smell a little...ammoniay?" the unicorn filly asked, hesitantly.
Scootaloo took a curious sniff.
"Nah, you're crazy," the brash pegasus said, "The icing totally smells like apples."

"Chocolate apple bundt cake!" Apple Bloom said as she leaned in to take her first bite.

Just then, the two biggest bundts in the whole class walked up: Diamond Tiara and Silver Spoon.

“What do you blankflanks have there?” Diamond Tiara asked nosily; her lackey Silver Spoon followed close behind her.
“None of your beeswax,” Scootaloo said. Trying to shield the cake from their view.

"Is that a slice of chocolate bundt cake?" Diamond Tiara said, circling Scootaloo like a shark, "You blankflanks shouldn't be eating such rich desserts. When it makes your butts bigger, your lack of cutie marks will be more noticeable."

The pink bully shoved Scootaloo to the ground as she dragged the slice away from the CMC. Apple Bloom and Sweetie Belle went to help their friend up.

"I'm doing your a favor," Diamond Tiara said, "You should thank me."
"Yeah, thanks for nothing." Scootaloo shot back.
"Ooh, nice retort," Silver Spoon said, sardonically, "Where'd you get it? The lame comeback-a-day calander?"

The CMC watched as Diamond Tiara split the cake slice into two pieces and gave one to her friend.
"I can eat anything I want, and I never gain weight," Diamond Tiara boasted.

The pink filly made sure all eyes were on her, before she took a big bite. She was determined hype how delicious this cake was, and taunt them for not having any.
After tasting it though, Diamond Tiara felt funny.

"Blech!" the pink pony said, retching, "You twerps tricked me! This cake smells like my dad's underwear drawer!"
"Your dad wears underwear?" Sweetie Belle asked, surprised.
"Only around the house on weekends," Diamond Tiara said defensively, the pungent aroma of the icing lingering in her mouth, "Shut up! Do I judge your parents quirks?"
"Every day," Sweetie Belle said, matter-of-factly.
"Still shut up," the pink filly repeated, "And that cake is garbage."

Their conversation was interrupted by a lustful groan.Silver Spoon was enjoying her portion of the cake a little too much.
"What are you talking about?" Silver Spoon asked her friend, while drooling, "This cake's the best! The icing makes it salty and sweet! I'll have your piece, if you don't like it."

"No!" Diamond Tiara said, curtly. If there was one thing the pink pony would not tolerate, it was giving something of hers away to a pony that wanted it. So, suppressing her gag reflex, Diamond Tiara forced herself to finish her half of the cake, opting to follow through with her plan to make the CMC jealous.
"You're right, Silver Spoon," the pink filly lied, as tears welled in her eyes, "This cake is delicious."

The CMC smiled, they could tell Diamond Tiara was having a miserable time, and they wanted to prolong it.
"Please give us just a tiny nibble," Sweetie Belle bluffed, "It looks so good."
"It...is," Diamond Tiara lied, as she forced herself to swallow another putrid bite, "and...(urp) that's why you can't have any."

Silver Spoon had long since devoured her piece of cake and was busy licking the last drops of icing from off the back of the notebook.
"Why is this so good?" Silver Spoon cried, "I can't get enough!"

Diamond Tiara sat on the ground, looking sick.
"Best...cake...ever," she whispered, her face going green.
Silver Spoon left her sickly friend's side and went crawling to the CMC.
"Please tell me where you got that cake!" Silver Spoon begged.

The CMC looked at each other. They all had similar thoughts. When Cheerilee comes back and finds out her cake's been tampered with, it won't be their fault.

Cheerilee was on her way back to the school. During recess, she popped into town to pick up a few things for her evening tomorrow with Big Mac.
"If I hurry," she thought, "I can eat my lunch before recess ends." Her mouth watered at the thought of tasting her special cake. The purple mare waved to her students playing outside as she entered the darkened classroom.

Walking over to the blackboard, Cheerilee was surprised to find Silver Spoon lying on her back underneath the desk. Her mouth was covered in chocolate. Icing dripped from her nose, and she was crying quietly.
"I couldn't stop myself," she sobbed when she saw her teacher, "Why does it taste so good?"

Cheerilee looked down at the filly and, after thinking for a moment about how to react, she smiled.
"It's okay, Silver Spoon," the purple mare said, "You remind me of myself when I was your age."
"So you're not mad I ate your cake with the delicious icing." the gray pony asked.
"Of course not," Cheerilee said as she helped the glutenous filly out from under the desk. The teacher pulled out a tissue and started cleaning off Silver Spoon's face.

"With an appetite like that," Cheerilee said, "in a few years you're going to make a lot of colts very happy."

Fluttershy

“I can't do this! I can't do this!” Fluttershy said, as she stared at herself in the mirror, hyperventilating, “This was a mistake!”

Fluttershy's heart pounded as she paced nervously in her cottage. She wanted to be with Big Mac, but she was so inexperienced. “I want to make him happy,” the pegasus thought, “but I don't know anything about how to please a stallion!”

The pegasus stared at herself in the mirror, taking several deep breaths.
"Calm down," Fluttershy said to herself, "Celestia picked you for a reason. You can do this."

There was a knock at the door. “Eeep!” Fluttershy squeaked. It was dusk. Big Mac had come for his virgin wife.

As Fluttershy timidly opened the door, she stared up at Big Mac. He looked down at her with loving eyes. His shaggy, light-auburn mane whipped around his head; carried by the warm evening air.
“You smell...nice,” Fluttershy said, blushing.
“I bathed,” Big Mac said, “I couldn't let you're first time be with some smelly work horse.”

“Please come in,” Fluttershy said, beckoning her husband inside.
Fluttershy had butterflies in her stomach as her husband moved past her. She looked at his thick, muscular legs; Strong legs that had spent a lifetime knocking apples off of trees. Those legs that would soon be used to drive his hard shaft into the accordion folds of her virgin marehood.

Big Mac had taken the liberty of preparing himself during his bath. His cock was already rock hard.

“We should probably keep things simple for your first time,” the stallion said.
“Okay,” Fluttershy replied, quietly, “Whatever you want to do is fine.”

“Just so you know, Rarity and Cheerilee have some...interesting quirks in the bed room,” Big Mac said, “Over time I've become good at indulging my wives in their fantasies. Is there anything you fantasize about?” Before she knew what she was doing, Fluttershy blurted out an answer.
“I've always wanted to be a tree.” she said, “Eeep!” The yellow mare covered her mouth. She blushed that Big Mac had found out her secret fetish.
The red apple farmer smiled at his wife.
“So, you want to be a tree, huh?” Big Mac asked, smiling.
Fluttershy didn't dare say a word, lest her mouth betray her again.
“Fluttershy, you're such a loudmouth,” she thought.

“Everypony knows that all the other trees are jealous of the apple tree,” Big Mac said as he picked up an apple off Fluttershy's table, “because they know that apple trees are the most beautiful.”
Walking back towards the bed, the stallion leaned in close to his wife and moved her hooves down, revealing her moist lips.

“My beautiful apple tree,” Big Mac whispered as he leaned in close and kissed Fluttershy. She could feel his hot breath against her cheek. His tongue pushed into her mouth, fondling her tongue with his own. The feeling was electric, and both ponies could hear Fluttershy's heart pounding in her chest. The yellow mare let out an involuntary moan, its sound muffled by Big Mac's delicious lips.
Breaking the kiss with an audible pop, Big Mac pulled his head back. Fluttershy leaned forward with her tongue out. She kept her tongue attached to his for as long as was possible. The pegasus sat there dazed, with her lips loose and limber. Big Mac took the apple and put it in Fluttershy's open mouth. The yellow mare bit down on it; holding it in place.

“Now you look like an apple tree,” Big Mac said proudly. He stared at Fluttershy. The deep crimson in her cheeks matched the apple she gripped tight in her teeth. She lay on her back with her legs open, exposing her privates for him. A small line of juice from the apple slid down Fluttershy's chin as she held it in place.

Big Mac walked away, then turned to look back at Fluttershy, as though he was seeing her for the first time.
“My my,” Big Mac said, getting into character, “I must have walked this orchard path hundreds of times, and don't remember ever seeing this apple tree before.”

Fluttershy's heart beat faster. More apple juice dripped down her chin. She sucked on the apple; trying to swallow the juice. She couldn't take her eyes off her husband.

“I've never seen a more beautiful tree,” Big Mac said as he circled around the foot of the bed, “Such full and shapely branches.”

The stallion rested his head on his wife's chest. He listened to her heartbeat, before slowly moving his tongue down her chest and over her stomach. Fluttershy's body tingled. The stallion kept heading southward until he arrived at her nether regions.

“Why I'll bet this tree's apples are the juiciest in all of Equestria,” Big Mac said as he stared at her glistening mound, “This tree is so juicy, that she has juice coming out of her knothole!”

Fluttershy moaned as Big Mac started to lap at her glistening sex. She was glad she had the apple to focus on. Concentrating on keeping it in her mouth helped her cope with the maelstrom of new sensations swirling within her body.

Big Mac teased her clit. Fluttershy's whole body twitched.
“I think this tree's ripe,” Big Mac said, “One swift round of applebucking and it should surrender its precious fruit.”

Big Mac rubbed his cock head against her pussy lips.
Breaking out of character, Big Mac addressed Fluttershy.
“This is your first time, so it's going to hurt,” the stallion said, “Once it's in, I won't move again until you're ready for me to keep going. Understand?”

Fluttershy nodded, the apple still in her mouth. She was scared, but she wanted this.

Big Mac pressed his cock against her virgin marehood. The stallion was struggling to make an impasse.
“She's tight,” Big Mac thought, “Too tight. Can I even get this in?”

The stallion leaned forward, trying to penetrate Fluttershy's unexplored snatch. Building up one large thrust, Big Mac rammed as hard as he could. The assault proved fruitless, and Fluttershy's cooch held firm.
The feeling of this hard object ramming against her private parts was a painful experience the pegasus hadn't counted on. The pain caused her to bite through the apple, sending it tumbling down her chest and onto the floor.
“It's too tight,” Big Mac said, as the sad realization dawned on him, “I can't get inside at all.”

Big Mac knew his third wife was shy,but he didn't anticipate her marehood to completely close up at the prospect of sex.

“You're so nervous, your body's tensing up,” Big Mac said, “If you're not in the mood, we don't have to do this. We can just cuddle.”
“Not in the mood?” Fluttershy thought indignantly, “What does he mean by not in the mood? I psyched myself up for him! I was ready! I want this!”

Big Mac sat beside Fluttershy on the bed. He put his arms around her as her lip began trembling.

“I don't understand,” Fluttershy said, “I want to be with you, Big Mac, I just don't know why my body won't corporate.”
“I think that even though you're ready up here,” Big Mac said, tapping her forehead, “You aren't ready down here.” The stallion then patted the top of her thigh.

“But what's the problem?” Fluttershy asked, “Am I just too small?”
“There's no such thing as a vagina that's perpetually too tight,” Big Mac said, knowlingly, “You're meant to bear foals, which requires much more serious stretching of your inner walls then what's required for a stallion.”

“Then why can't I stretch myself for you?” she asked, on the verge of tears.
“You're body isn't ready for sex,” Big Mac said, compassionately, “You're too stressed to open up your body for me.”

Fluttershy had never felt more mortified in her life. Even though she was willing, her body was unable to accept her husband's stallionhood, because of her crippling shyness.

The inaccessibility of his wife's pussy had killed Big Mac's boner. Both ponies felt sad and emotionally drained.

“It's alright,” Big Mac said as he lay beside his wife, “Let's just go to bed.”
Big Mac closed his eyes and quickly drifted off to sleep, exhausted after a long day of apple bucking. As the stallion dreamed, Fluttershy lay awake beside him. The pegasus put her arm across her husband's barrel chest and hugged him tight. Tears streamed down the mare's yellow cheeks as she quietly sobbed.
"I'm sorry, Big Mac," she whispered, "I'm sorry."
