The Strange Designs of the Elements of Harmony

The sun was shining brightly that morning over the vast fields of Sweet Apple Acres. Summer had just begun, but the heat was being especially bothersome even though it had barely been three hours since sunrise. Applejack had been working since then, taking advantage of the cooler hours of the day, but those were already beginning to give way to an unbearable heat.

Sacks were stacked on a porch in front of the huge barn on the lot, and Applejack was loading them on a small wooden cart.

"Applejack! Hey, Applejack!”

Applejack put the two sacks she was carrying on the cart and took off her hat to fan the sweat from her face. She looked around, but couldn't see anyone.

“Up here!”

Applejack looked up. About fifty feet in the air she could make out Rainbow Dash's unmistakable prismatic hair, waving her arm from a small white cloud.

"Ah! Hello, Rainbow!” The farmer raised her arm in greeting as well. “What brings you here, pardner?”

Rainbow flapped her wings and descended the fifty feet to the ground, landing lightly in front of Applejack and kicking up a small cloud of dust.

"I've just finished clearing the clouds from my area today, so I thought I'd take a break around here," Rainbow replied as she brushed the dust off her clothes with one hand. “Good thing about this place is that it’s not far from my work area and it’s very quiet. Perfect to relax for a while!”

"Relax for a while or take a good nap?" Applejack showed a smug smile. “Maybe not today, but Ah've already heard yah snorin’ from down here several times.”

Rainbow blushed and made an indignant gesture. It had been a few weeks since she had been using the Sweet Apple Acres area as a resting place after her morning rounds, but it seemed that she hadn’t been as low-key as she had hoped.

“I don’t snore!” Rainbow crossed his arms and looked away angrily. “And I only give my eyes a little rest before doing my training exercises! It's an essential part, you know.”

Applejack gave a friendly laugh as she put her brown hat back on.

"C’mon, don't get mad, Rainbow." She walked back to the porch and scooped up a couple of sacks in her strong arms. “Hey, that means you're going to get with your training now, right?” she said while she returned to the wagon and unloaded the packages. “Yah can do it here if yah feel like it.”

"Well, I usually train near the lake to take a dip as soon as I'm done," Rainbow answered. “But if you want to see this pony working out, I will gladly put on a show for you.” She drew her fists to her waist and puffed out her chest confidently.

"Ah'm sorry, Dash. Ah can't watch you right now.” Applejack pointed a thumb at the wagon. “But when Ah'm done carrying these compost sacks Ah'll take a break. It shouldn't take long.”

"Meh, okay." Rainbow was about to turn around and continue with her eye rest, but she thought about it for a few seconds and said, "Hey, do you want me to help? That way you will finish your chores faster and you won’t miss a single minute of my awesome workout.”

Applejack looked Rainbow up and down. She was quite thin and short, at least slightly more than what the Pegasi tend to be, who were already the smallest of the three tribes. She, however, had a truly athletic body, more suited for speed than strength. She wore a black sports top that left her lean but wiry arms completely exposed, in addition to her toned abs. The muscles of her strong and not-so-thin thighs were clearly marked in her tight black leggings, evidencing the results of her training. In addition to her thighs, there was a bulge that was also very clearly marked, but she preferred not to look at it too much at the moment…

On the other hand, Applejack was a rather tall pony, to the point of being a head higher than Rainbow. Among the three tribes, the earth ponies were the most vigorous and stoic, which added to her specially hard work in the fields, had given Applejack a strong and toned body. Her arms and legs were thick and muscular; actually better suited to the strength and endurance her trade required, and were also visible through her short jeans and short-sleeved red shirt.

Applejack didn't consider herself a particularly vain pony, but she really did take pride in her physique.

“Help me? Oh sure. Thank yah very much,” Applejack replied. “Yah are somewhat skinny, but it’s not like we are doin’ heavy work, or anything.”

“Hey!” Rainbow yelled angrily. “I may be a little skinny, but you won't see a pegasus faster than me in all of Ponyville!”

Applejack laughed out loud as she stepped in front of the cart to drag it away.

"It's funny you say that! Ah suppose yah don't know because you've only lived here a few months, but you’re watching the pony that won the Running of the Leaves last year.” Applejack gave the pegasus a smug smile. “Of course, Ah'm an earth pony, so you might be the fastest pegasus in all Ponyville.“

"If I had been there I’d have swept the ground with you, for sure!" Rainbow crossed his arms and snorted indignantly.

"Well, the race will be held again in a few months, so we'll have a chance to check it out." Applejack pointed to the back of the wagon. “Can you help me push?”

Rainbow continued with her arms crossed and looked away from the cart as she pouted.

"Now I don't know if I feel like it."

Applejack shrugged and started pulling. Rainbow kept her gaze averted, impassive, until…

“Wait!” Rainbow yelled as she caught up with Applejack and started to push the cart from behind.

"Well, these are the last sacks," Applejack declared as she dumped them on the floor and dusted off her hands.

It was almost ten in the morning and the heat was getting more intense. Applejack had rolled up her plaid shirt to her shoulders and unbuttoned the first few buttons so she could feel some air on her sweaty chest.

"I still don't understand why we have to bring these sacks of shit and leave them lying around," Rainbow commented as she tried to cool off her sweat by flapping her wings.

“They’re no ‘sacks of shit’, it’s nitrogen fertilizer.”

"Yeah, that’s what I said."

Applejack sighed and rolled her eyes.

"We've brought them here so ah can scatter them tomorrow," she replied as she fanned out her cowboy hat. “It’s a special fertilizer that dissolves in water to have a greater effect, but since ah don't have to water my apple trees until tomorrow, ah thought ah could bring them today to get some work done.” Applejack put on her hat again and stepped in front of the cart to pull it again. “Let's take the cart back to the barn and refresh ourselves a bit. This heat is starting to get annoying.“

Although it was empty now and felt like it wasn't much needed, Rainbow got behind the cart and helped push it just as she had done before.

"That’s the schedule for Ponyville according to our weather coordinator: Heat and clear weather for the next five days," the pegasus commented.

"Five days in a row?" Applejack made a listless gesture. “Why aren’t we gettin’ a rainy day in the middle, at least?”

"It is what it is," Rainbow replied with a shrug as she kept pushing. “It must be hot In summer, and cold in winter. This is what they taught us in the climate planning course. And we'll have some rain in a week anyways, so that’s something.”

"What a load of shit…”

A few moments later they were back at the barn. Applejack put the cart inside and after a few minutes produced a couple of wooden jars of sparkling amber liquid.

"Time to freshen up our throats!" Smiling, she handed Rainbow Dash one of the jars. “Here yah have.”

Rainbow picked it up and studied its contents carefully.

“What is this? Cider?” Rainbow asked as she sniffed the yellow liquid. She had never seen one so sparkling.

“Exactly! It’s not made with the best apple variety to make cider, but it’ll sate your thirst for sure!”

Rainbow had doubts, but she decided to have a sip. She felt the golden liquid slide down her throat, leaving a fresh and pleasant apple aftertaste on her palate. The pegasus had drunk cider many times, but she had never tasted such a delectable and refreshing one.

"It's... it's delicious!" Rainbow exclaimed before taking a big gulp this time.

“It is? It's probably because of the special touch ah've added to it,” Applejack commented innocently.

“Seriously? And what is it?” Rainbow took another thirsty swig from her mug, larger than the last one.

Applejack looked both ways and brought her mouth to Rainbow's ear.

"Ah took a good piss in your jug..."

The shocked pegasus dropped the jug to the ground, and all the cider inside her mouth shot out in a powerful stream forward. Applejack laughed loudly as Rainbow coughed and spat to try to expel all the vile liquid.

"Ah couldn't help it! Hahaha!” Applejack laughed out mockingly as she patted her knee. “Yah should have seen your face!”

Rainbow shot her a dirty look as she clenched her fists. Obviously there was no urine in her jug, but her imagination played tricks on her for a few seconds.

"I’ll give it back to you, Applejack," Rainbow grumbled. “You’re gonna remember this.”

"Sorry, sorry!" Applejack replied, having already calmed her giggles. She, then, offered Rainbow her jug, still full. “Here, ah haven't tried mine yet.”

Rainbow eyed the jug suspiciously for a few seconds, but reluctantly accepted it and took a large gulp. That cider was still exquisite; a real delicacy.

As she let the pegasus cool off her throat, Applejack decided to bend down to pick up the mug that Rainbow had dropped, and the pegasus couldn't help but glance at the rear in front of her.

Rainbow was someone who took her exercises very seriously. After all, her biggest dream was to be a member of the Wonderbolts, and physical performance would play an important role in choosing the candidates the next time the entry-level spots opened. Those tough exercises had given her a strong, lean, and wiry body that she was very proud of.

But the ass that she had in front of her was spectacular.

Those buttocks must have been almost twice the size of hers; really voluptuous but, at the same time, strong and firm looking. Rainbow was sure the farmer's short jeans had to be one size smaller than they should be, because that ass looked so tight against her garment. The pegasus couldn't help but bring her hand closer to that splendid butt of hers while Applejack wasn't looking…

...And she slapped it loudly with all her might.

"Auch!" Applejack flinched and turned, totally flushed. “You…! Get back here, yah winged varmint!”

The farmer ran after Rainbow Dash, but she already had a good advantage considering that she had taken flight.

Rainbow laughed with all her might, clutching her belly and pointing a finger at the farmer, already out of her reach. “What goes around comes around, AJ!”

"Get back down here right now!" Applejack yelled indignantly, clenching her fists.

"Oh come on, Applejack! Don’t be angry, it was just a small pat!” Rainbow did a quick pirouette in the air. “Since I'm up here already I'm going to start my training. Get comfortable and enjoy the show!”

The farmer picked up the other jug, clenching her teeth, and went back into the barn for a refill. She still hadn't had a drink and she was thirsty. She moved the container to the spigot of one of her cider barrels and filled it to the brim, grumbling. That damned sassy midget! How dare she slap my ass so shamelessly? Applejack took a drink to try to calm herself. The amber liquid slid down her throat and the pleasant taste soothed her a bit. With a sigh, she was going to leave the barn, but noticed that her short jeans were tightening her crotch more than it should. Applejack looked down at the large bulge snaking around the waistband of her jeans. Fuck! It had to be now! She still had in mind the moment when Rainbow's palm made contact with her butt, and she didn't quite understand why she was so annoyed by that simple joke. Perhaps…?

... She liked it when Rainbow touched her ass?

Applejack had to admit that she liked hanging out with Rainbow Dash. Despite being quite cocky, the truth is that she was a helpful pegasus, funny and, as her element, very loyal. But she saw her only as a friend, nothing more. Besides, Applejack only liked stallions... Or maybe not? It was true that she had taken a look at Rainbow's body, maybe more than she would consider polite. But of course, she wore very tight clothes that left little to the imagination, and she had an enviable physique. Slim but with fibrous muscles, very marked abs, perky breasts, very firm hips…

...And a very large package.

The lump in Applejack's groin trembled again.

No! Don't think about it anymore! She shook her head, blew out a breath to try to calm herself, and headed for the barn door.

"Hey, Applejack!" Rainbow landed just then in front of the entrance and looked around for her friend. Spotting her at the back of the barn, she glided over to where she was. “You've been here for ten minutes and I was getting worried.”

“That much?” Applejack cleared his throat. “Ah'm fine. Ah just needed to calm down a bit.”

"Sorry, I didn't think that would bother you so much. It was just a joke without bad... Oh... Oh!” A mischievous grin crossed Rainbow Dash's face. “Hehehe! Now I see what you meant by "calm down a bit".

Applejack swallowed hard and looked down. The bulge in her crotch was perfectly visible through her jeans. As soon as she realized she tried to turn her back on Rainbow, but she kept poking her head above Applejack’s shoulder in an impertinent way.

"Wait… don't tell me you got a boner because I slapped your ass!"

Applejack's bulge trembled.

"N-No!" The farmer snapped, totally flushed. “It’s just a coincidence! Yah know how this thang can... swell up at the weirdest moment.”

Rainbow shot her an incredulous look.

"Yeah, yeah... Whatever you say, AJ." Rainbow walked over to a bale of hay and jumped onto it. “Now that the topic has come up, how are you hanging with this whole cock thing? We've had them for five days, right?”

Applejack tried to remember that nightmarish morning. She had never been so scared in all her life when she woke up. Any mare would have been if she had woken up with that tremendous erection when the night before was totally devoid of male organs. With the shock still in her body, she thought that if anyone could clarify how that huge tool had appeared between her legs, that was Twilight. She hadn't known her for a long time, but Twilight already made it clear that she was quite a brainiac.

Without further thought, she dressed as fast as she could, trying to hide her stud parts as best as possible, and she sped off to the library without ever having exchanged a word with her family.

It may have been due to the deep shock she suffered, but on the way to Golden Oaks she was fortunate enough to have her erection calmed down, making her crotch more discreet. However, not enough for anyone who saw her to notice that there was something there that shouldn’t be.

Once she got to Twilight’s, when the sun was still rising over the horizon, she was surprised to see that Pinkie Pie was there, and that shortly thereafter Rainbow Dash and Rarity arrived. Apparently they all shared the same problem. Fluttershy did not appear, though - probably because she felt too embarrassed about this whole situation.

After the five friends were reunited, Twilight shared her impressions and theories about those new male genitalia and assured that she would try to contact Celestia that same day to gather more information. For now, according to her deductions, and after performing a small magic scan, she was sure that all this wasn’t a harmful curse and that it was related to the Elements of Harmony.

After that short chat, Rarity offered to reassure Fluttershy and let her know all the information Twilight communicated to them, and then they each tried to get back to their daily chores.

“Yeah. Ah still find it hard to believe that these thangs have anythin’ to do with the Elements, but Twilight was completely sure of it.” Applejack scratched her head. “And well, it's… weird. And troublesome. It doesn’t stop swelling at the most inconvenient moments. Now ah understand what Big Mac goes through…”

“Oh yeah! Big Mac! I’ve heard that he’s a true legend. You know why.“ Rainbow brought her palms close and moved them almost shoulder width apart as she puffed out her mouth.

“Hey! Don't say that in front o’ me!” Applejack got closer and patted Rainbow’s hands to stop her obscene gesture. “You’re talking about mah brother!”

Rainbow held back a laughter and she leaned to the side to get away from the menacing - and sexy - figure of Applejack.

“Oh, I wish I had a brother as hot as yours..."

The farmer decided to ignore that comment and sat down next to the pegasus.

"What about yah, Rainbow? How are yah handling all this?”

Rainbow looked down at her groin, then at Applejack.

"It's pretty weird at first, but you get used to it. Although, like you said, you can get a stiffy at the most inopportune moments. And then it’s impossible not to see it.”

"Yeah, it’s the same with me," Applejack said, blushing. “Ah’m sure you noticed already.”

“No, no. I mean, it's impossible not to see it. Literally.”

Applejack was puzzled and looked down at Rainbow's package. The leggings she wore were quite tight, but they didn’t reveal anything too exaggerated. Well, maybe the bulge was a bit on the bigger side, but it didn't seem too noticeable.

"Well…" Applejack said. “With the clothes you wear, it would have to be really small to go unnoticed.”

Rainbow Dash sighed.

"How could I explain it to you…?" The pegasus thought for a few seconds until something came up to her. “I know! Do you remember this?” Rainbow made the same gesture she did when she was talking about Big Mac: She brought her hands together and spread them almost shoulder-width apart as she puffed out her cheeks.

“How could ah forget? That image will haunt me mah whole life…” Applejack answered with an annoyed expression.

"Well, let's say I fell short."

Applejack looked at her incredulously.

"Haha, very funny, Rainbow."

The pegasus gave him a smug smile and crossed her arms.

"Oh, you don't believe me? I bet mine is bigger than yours.”

Applejack was speechless for a few moments. Was Rainbow implying what she thought?

"Rainbow, are you telling me yah want to compare dick sizes?" she asked, surprised. “What are yah? A foal?”

Rainbow smirked. Far from being ashamed, she felt more determined to propose her game.

“I have an idea. Whoever has the biggest rod can do whatever she wants with the other for an hour.” Rainbow looked closer to Applejack. ”Whatever she wants. What do you say?”

The bulge in Applejack's crotch, which had been calming down, trembled again. She lost herself in Rainbow's deep cerise eyes as she thought about that proposition and what she’d do if she won her bet. She quickly realized what she was doing and shook her head.

“No way.”

"Are you sure, AJ? Remember: the winner will have an hour to do what she wants with the loser," insisted Rainbow, wagging her eyebrows.

"Ah said no, and that’s final!"

Rainbow looked like she was going to answer her again, but remained silent for a few moments and made a disgruntled gesture.

"Bah, you’re no fun." She said, then laid her back on the straw bale with her hands on her neck.

After that sentence, the couple remained in awkward silence for a few minutes.

"I have to confess something to you, AJ," Rainbow said suddenly as she placed her right palm in front of her own face, watching it closely.

Applejack looked at her friend curiously.

"When you bent down to pick up that mug," Rainbow said, "the first thing that crossed my mind wasn't slapping your ass."

"W-what do yah mean?"

“My first thought was how much I wanted to touch it and squeeze it, so I reached out to do it," Rainbow continued. “But at the last moment I felt afraid of how you might react, and instead I gave that smack and pretended that it was all a joke.”

Applejack was speechless.

"When you left I thought about what a coward I was. I wanted to come down right away to apologize, but…” Rainbow paused for a moment, as if she were wondering whether to continue. “B-But I didn't want to go down there because I got a hard-on. And believe me when I say that it’s impossible to not see it. I didn't want you to realize how much that situation had turned me on.”

Applejack gulped, but she didn't say anything, so Rainbow resumed her heartfelt words.

"I tried to warm up a bit to make it go down. I've found that exercising can help to…”

"Rainbow…" Applejack interrupted the pegasus by shaking her shoulder slightly and pointed to her leggings. During that confession Rainbow's pack had been growing steadily. It went down her leg, almost to her knee, and ended with the tip of a thick cock shyly peeking out of her garment.

"Ugh! I start talking about you and look who shows up now…” Rainbow grumbled as she ran a hand over her face. “You see? It’s impossible not to.”

Applejack thought about those words for a moment.

"Yah mean yah got like that because of me?" She asked.

Rainbow lifted her back from the hay bale and stared at her friend.

"How could I not? Have you seen your body, AJ? Your tits are huge and you have an amazing ass! You even make me envious and all!”

Applejack looked at her figure and blushed. It was true that her butt and her boobs were somewhat larger than normal, but she was well behind some of her friends, so she didn't think they were anything that special.

"Well, yeah, but…”

"And I'm sorry I tried to bait you with that stupid bet to see who had it bigger." Rainbow looked away. “I know it was foalish.”

Silence.

"Do yah still want to do it?"

This time it was Rainbow who got speechless for a moment. She looked back at Applejack, who was smiling gently.

“Do what? C-Compare dicks?” Rainbow stuttered. “Well, only if you…”

“Same bet: Whoever has it bigger can do whatever she wants with the loser for an hour.” Applejack offered her a hand. “Okay?”

Rainbow looked at her skeptically. She wasn’t sure why Applejack had changed her mind so suddenly, but she finally accepted her hand.

"Okay, deal," she said as she shook it firmly.

After that, Applejack stood up and fumbled slowly with the buttons on her jeans. Once she was able to unbutton the first one, she let out a sigh and proceeded to unbutton the rest. After that, she caught the garment around the waist and lowered it to her knees, then dropped it to the floor with a jolt. The only thing that now separated her private parts from Rainbow’s gaze was her underwear.

"Aren't those boxers your brother's?" Rainbow asked, keeping her eyes on that bulging crotch.

Applejack looked down at the baggy white underpants she was wearing. A large green apple cut in half was sewn on one side.

"Ah forgot ah was wearing them…" Applejack said quietly. “It’s all ah have until Rarity knits me ones. The panties ah have are too tight, you know?”

"You're lucky," Rainbow replied. “I have to go without underwear meanwhile.”

Applejack continued what she was doing. She picked up the boxers and slowly slid them down her strong orange thighs until they were under her package.

Rainbow was speechless for a moment. Between Applejack's legs hung a thick ocher member that reached almost mid-thigh. It wasn’t stiff yet, but that cock must have been almost eight inches, with a thickness that was already approaching Rainbow's wrist. But what had really astonished her were the huge testicles that hung beneath that dick, smooth and big as a pair of grapefruits.

"G-Good thing we're just comparing cocks," Rainbow blurted out, "because those balls are enormous."

"Ah know," Applejack replied as she finished pulling her boxers down, setting them on the floor. “It’s quite annoying to have them squeezed inside these jeans.”

Seeing that her friend was already naked from waist down, Rainbow decided to get up from her seat and imitate her friend. She grabbed her leggings around her waist and lowered them to her knees, causing her stiff cock to spring against her toned abs, remaining bent over forty-five degrees.

Just as she had hinted, that cock was tremendous in length, probably over a foot, and a width that rivaled Applejack's. Under that gray-blue limb hung a pair of thick, masculine balls. They had a good size, but were well below her friend's.

“Phew!” Rainbow sighed with relief. “Much Better. These leggings are really annoying when my little friend wakes up.”

Rainbow took her member with one hand and shook it slowly. Applejack was surprised to see that the pegasus' cock was still not fully erect. As Rainbow had said, Big Mac's dick was something of a legend in Ponyville; and many times a topic of conversation among the young mares in town. However, she was sure that the one in front of her was already superior. And it was growing even more…

Thirteen inches… Rainbow's thumb was distancing itself from her middle finger as her member was getting thicker, and its virile veins began to puff up obscenely. Fourteen inches now… The stiffness of that big cock reached its limit, making it stare at the roof of the barn and reaching just over fifteen impressive inches. Rainbow continued to slowly massage that thick monster that she could no longer surround with her hand while bountiful drops of pre began to flow from the tip, sliding down its bulky shaft and reaching her fingers.

"What do you think, AJ?" Rainbow asked confidently as she brushed a lock of her prismatic hair away with her free hand. “Not bad, right?”

Applejack was staring at the rod in front of her. It was colossal, especially when compared to Rainbow's relatively small body.

"It's huge…" Applejack whispered. She could barely look away from the member that Rainbow was still fondling. She didn’t expect such a size.

"It's the biggest cock I've ever seen. And believe me, I have seen quite a few,” Rainbow boasted, showing a superior smile. “Do you think you will be up to the task? If you don’t feel up to it, you can fold and we cancel the bet.”

"No way," Applejack said simply, who had already started massaging her own member. “Ah'm not going to back down now.”

“That’s cool. Even better for me.”

With those gentle movements the blood flowed to Applejack's thick cock, causing it to gain more volume. With each heartbeat her member lifted and lengthened several millimeters. When it seemed that it had reached its maximum extension, it seemed to continue to grow a little more, inexorably. She was already surpassing even the best endowed ponies in length, but the beastly thickness of the imposing cock was already making them look ridiculously scrawny. Applejack's hand barely encircled just over half of her rod, far exceeding Rainbow Dash's width. And it still seemed to keep growing slowly…

"Ah’m sorry if it’s takin’ a while, but this thang takes its time before it's fully grown," Applejack commented casually, then continued massaging her cock using her two hands.

Rainbow's confident expression had completely disappeared. She couldn't believe what her eyes were seeing. The behemoth Applejack was holding continued to grow, puffing up like a balloon, gaining even more thickness, until it finally stopped.

"What the fuck, AJ…" This time it was Rainbow who was stunned. “I-It’s so fucking fat…”

Applejack had tried to remain impassive, but she couldn't help but show a barely perceptible evil smile after Rainbow Dash's last sentence.

"Well, let's compare sizes." Applejack walked over to one of the straw bales and sat on it with her legs at the side of it, leaving her massive balls and colossal tube of meat in full view. “C’mon, Dashie. Sit in front o’ me.”

Dashie… It was the first time Applejack had addressed her by that name. Rainbow was used to being called that from time to time, but for Applejack to stress that diminutive right on that moment…

"Do we have to do it like this? Seated face-to-face?” Rainbow asked uneasily.

"Dashie, Ah'm, like, a head taller than you," Applejack explained. “We don’t have our crotches at the same height, so it’s best to be sat down to compare. Ah don't have anything right now to measure them so this will have to do.”

Rainbow thought about it for a moment but she didn't move.

"What are you waiting for, Dashie?" Applejack asked with a smug smile as she massaged her massive tool to keep it hard. “We don't have all day.”

Rainbow shook her head and finally walked over to the straw bale. It wasn’t very long, so she had to position herself less than a foot from Applejack. She spread her legs and sat before the farmer, resting her big balls on the soft straw and pointing her tremendous erection at her friend. It was harder than in any of the previous five days.

"Now we put them side by side, horizontally," Applejack explained as she leaned hers forward and placed it against the pegasus' shaft.

Rainbow tried to suppress a groan as both cocks made contact. Applejack's bulk was completely soaked by the pre oozing from her tip, surrounded with pulsing veins as thick as macaroni. Holy Shit! How can it be so fat? Rainbow's cock was already tremendous, but the one in front of her must be twice as thick. Maybe even more. It was so bloated and hot it looked like her glans was going to explode. And those balls… Damn! They were bigger than she thought! Did they swell up or was it her imagination? They could practically squash theirs...

Applejack decided to shorten the distance between them even more. They were so close that Rainbow's face was almost on the farmer's voluptuous cleavage. Rainbow, however, lowered her gaze as she felt a pleasant pressure below.

"My, my, Dashie." Applejack didn't stop showing her confident smile despite what she would say next. “It seems that you win: you are touching my pelvis with your tip and I still do not.” She put a thumb on her own tip, trying to cover the distance that separated her from Rainbow’s crotch. “You must be about an inch longer than me.”

…

What?

Rainbow verified that, indeed, her penis was touching Applejack's body and while she wasn’t. Were they completely aligned? Yes, there was no doubt.

But…

"Are we just counting how long it...?"

“Okay! A bet is a bet,” Applejack interrupted with a mischievous grin as she released her thick cock and springed up again, pointing toward the ceiling. Then she put some distance between her and Rainbow. “Yah have an hour to do whatever yah want with me.”

Rainbow was confused. At first she felt very confident; she was sure that she would win that bet without any kind of problem. After all, it was true that the tool she had between her legs was the largest she had ever seen. It even dwarfed what she saw in her sizable collection of porn magazines!

However, her doubts began to assail her when she saw the enormous size of Applejack's balls. And they continued to assail her when she checked the beastly thickness of the farmer's cock. She thought that she had been lucky when the Elements distributed the sizes of their new male endowments, but is it possible that her friends had such a brutal size? Or... Could they be even bigger?

Even though she had technically won the bet, Rainbow's arrogance had faded. And there was another question: Why did Applejack seem so confident despite losing the bet? What's more, why had she settled for just comparing the length without complaining when she clearly beat Rainbow in all other measurements? Applejack had always been a very competitive pony, so that wasn’t like her. Perhaps…?

"We don't have all day, Rainbow," Applejack commented impatiently. “Or are you afraid, maybe?”

Rainbow came to herself and shook her head vigorously.

"No way!" she answered automatically. “I'm not afraid of that little...! Uhhh…” Rainbow was very prone to fall under that kind of teasing, but she thought it would be better to cut to the chase and get down to business. If Applejack accepted her defeat so easily, then by Celestia she was going to take advantage of it. “Okay. Take off your shirt.”

Applejack clicked her tongue as she kept her mischievous smile.

"The prize for winning the bet was to be able to do whatever you want with the other's body, but that doesn't mean I have to do everything you order." She put her arms behind her back and pulled her chest out, making her big melons stand out even more against her red shirt. “Why don't you take it off yourself?”

Rainbow gulped. The pressure of those tits were going to pop the buttons of Applejack's shirt at any moment. She brought her hands firmly to the lascivious orbs and unfastened the first button, easing the pressure on them. As soon as she unbuttoned the next one, Applejack let out a small sigh of satisfaction, and when she reached the next one, she realized a small problem: the colossal cock of the farmer blocked the rest of the buttons, so she wasn’t going to be able to release them without touching it.

Who cares? She was going to do it sooner rather than later.

She slid her hands behind the bulky mass to feel the buttons and couldn't help but brush it with the back of her hands. Holy Luna, it’s so hot... With a little effort she unfastened the entire garment, revealing a red bra that harshly contained Applejack's glorious breasts. They were much bigger than hers, probably a G cup versus her C. Rainbow never developed really big teats even though pony mares were prone to it. She was sure that happened because her sporty lifestyle burned the fat that had to accumulate in her breasts. Or so she wanted to believe, because her mother was more endowed than she was in that regard…

She leaned closer and ran her hands over Applejack's hard shoulders to remove her plaid shirt. She was so close to her that with each movement her long cock touched the plump tits and the fat dong of the farmer. They were hard to avoid with such a long member.

Rainbow bit her lip, trying to hold back a groan.

"I see little Dashie is impatient." Applejack kept showing her lewd gaze as Rainbow pulled her shirt down her muscled arms.

“Oh, shut up.”

Rainbow got up, seething, and got behind Applejack to finish removing her garment. The farmer stretched her hands back a little so that her sleeves went through them. With the shirt already out, her broad, chiseled back appeared in front of Rainbow’s lascivious look. Damn, she’s ripped.

Rainbow brought her hands up to the clasp of her friend’s bra and unbuckled it. She then slid them up to Applejack's shoulders while she bent over to help the pegasus remove her garment, until only the cups of her bra remained glued to her body.

"My girls want to get some fresh air," Applejack said in a honeyed voice and flushed cheeks as she impatiently wagged her blonde tail.

Rainbow sat behind Applejack, her huge member clinging to the farmer's back. She reached her hands under Applejack’s armpits to remove her bra completely, tossing it aside carelessly. Rainbow immediately started massaging the farmer's large breasts with her hands. She rocked those fat, malleable tits firmly, as if she was kneading bread, while Applejack was moaning slightly.

Due to their height difference, Rainbow had to get up from her hay seat in order to rest her head on Applejack's shoulder. She wanted to observe how those thick and succulent tits were being deformed by her hands. As she did so, however, she realized that something was looming between them: The colossal brown obelisk of the farmer, firm and imposing.

"Shit, AJ," Rainbow exclaimed without stopping her hands as she performed pelvic movements against Applejack's back. “Your fucking tits are so fat, and yet they can't be compared with your monster of a cock.”

The pegasus changed her hand movements and began to rub those huge udders against Applejack's virile member, which kept oozing pre in obscene amounts.

"Nnngff…" Applejack couldn't help but groan. “Tell me... how much you like it.”

"I adore it," Rainbow replied without hesitation. “It’s so fat; a fucking behemoth.” Rainbow released one of her tits and took Applejack’s thick rod. She needed to feel it in her hand. “Fuck, it's so thick that I would need both hands to fully encircle it. I don't think there is a cock as fat as yours in all of Ponyville. What am I saying? Maybe in all of Equestria!”

Rainbow's hand shook that enormous tube of meat repeatedly, noting every huge throbbing vein that adorned it. Schlick, schlick, schlick. The copious, slippery presemen that covered it helped her hand slide easily along the towering beast.

Applejack was barely trying to contain her moans, and Rainbow took that as a cue to pick up her pace. She let go of her friend's other breast, took hold of her colossal member, this time with both hands, and began to shake it with much more intensity. Applejack's grunts of pleasure rose in volume, and the farmer began to shake her hips in time with those movements, as if she was trying to fuck Rainbow’s hands.

"Holy Ce-Celestia!" Applejack managed. “I'm going ... I'm going to cum if you keep up like this!”

At that moment, Rainbow released the cock and sat up. She didn't want Applejack to waste a good cumshot, so she stepped in front of her and knelt down to face the beast head-on.

Seeing the position Rainbow was taking, Applejack sat closer to the edge of the straw bale, leaned her back behind and spread her legs wider to allow him full access to her private parts.

It was her or were Applejack's balls even bigger than a few minutes ago ...? Rainbow could have sworn that those prodigious gonads had gained about an inch in thickness. Those semen factories must be working hard. As she grasped and massaged that fat cock in front of her, Rainbow felt one of those testicles with her hand. She could almost feel the cum splashing inside them, eagerly waiting to be released.

However, it didn't take long for Rainbow to leave the huge nut and direct her hand lower.

"Nnnnnfff!" Applejack could barely contain a squeak as she felt the pegasus's fingers groping her love tunnel.

Rainbow had no problem inserting her middle and ring fingers all the way. All that previous warm-up had also turned on Applejack's feminine parts, so her pussy was abundantly lubricated. Those fingers moved loosely inside those silky walls, so Rainbow inserted one more and began to piston her hand, making Applejack moan and shake. The lewd, muddy sound of those movements could almost be heard over the guttural noises of the bulky farmer.
"I wanted to get you ready for the main course, but I see you're already wet enough." Rainbow removed those fingers and released the farmer's cock to direct her own tool against Applejack’s soaked cunt.

"C’mon, Rainbow," Applejack gasped as she leaned back on the straw bale. “Ah can’t take it anymore…”

Rainbow caressed the entrance with her tip, toying with the idea of inserting herself.

"So I'm not ‘Dashie’ anymore, huh?” The pegasus smiled mischievously. “I don’t know. You don’t seem to want it that much…”

"Come on, put it in now…" Applejack muttered under her breath.

"Oh, I think I heard something." Rainbow put a hand behind her ear in a mocking gesture as she continued to brush Applejack's lower lips with her cock. “What do you want me to put in? You’ll have to speak more clearly.”

"Put your dick inside me, Rainbow!" Applejack exploded, finally. “Ah want yah to fuck me with that beast of a cock right now! Break mah cunt!”

"That's what I wanted to hear."

Without further ado, Rainbow thrust the tip of her huge cock into Applejack's wet tunnel. The massage that she had applied before had dilated the pussy enough for her considerable glans to enter without problems. However, she was barely able to insert half of her member before meeting resistance.

Rainbow had already masturbated many times these days. Much more than she would be willing to admit even to her close circle of friends. After all, who wouldn't be curious to try? She had even given herself blowjobs thanks to the exceptional length of her cock.

However, despite the great pleasure she felt during her onanist practices, having her member inside Applejack's pussy was on a whole other level. The pressure of the wet, soft folds of that cavity aroused her in a way she had never felt before.

And she wanted more. She needed more.

Rainbow's hips began to move on instinct; she pulled out a few inches of her imposing cock and then reinserted them. With each of her jerks, she penetrated Applejack’s delicious pussy more deeply. First half inch, then one, one and a half... With each movement she was able to gradually insert her huge rod, her movements becoming longer and longer, until she reached a point where her pubis touched Applejack's gigantic balls with each piston strike.

Plap, plap, plap, plap…

The dirty noise of meat against meat echoed through the spacious barn. Applejack had been clenching her teeth at first, trying to contain her growls of pleasure, but by then they were impossible to restrain, desperate and loud. Her tongue hung down from her mouth, drooling lewdly, and her eyes were beginning to roll. Her cunt contracted, squeezing Rainbow’s cock like a vice as she came profusely on it.

Rainbow, meanwhile, had closed her eyes to focus, pressing her cock harder and harder against Applejack's tight tunnel, until she suddenly felt a delicious and familiar sensation in her bulging gonads…

"A-Applejack! Here I come!”

With one last push, the virile pegasus inserted the few remaining inches to fully thrust her plump stallionhood into the burly farmer's cunt. Her balls contracted, and a powerful stream of cum shot from her massive cock, painting Applejack's insides white. Each of her fertile jets seemed to be more abundant than the last, causing Applejack's gut to swell visibly.

Rainbow didn't know how much time had passed. Those seconds of orgasm seemed like hours and she still expelled abundant cum from her imposing cock. Finally, her balls relaxed and she dropped onto Applejack's naked body.

Both ponies panted, gasping for air after that strenuous exercise, their bodies completely drenched in sweat.

"T-That was fantastic, Rainbow," Applejack declared with one forearm resting on her forehead. Next, she shot a mischievous look at the exhausted pegasus. “But bein’ honest, yah came too fast. Ah was hoping yah would hold out a little longer.”

Rainbow felt a hard, throbbing pressure on her stomach and realized that she was crushing the farmer's massive member against her torso. Despite wearing her top, she could feel the warmth and wetness of the gigantic cock through her own garment.

The pegasus sat up, her cock still impaled on Applejack's pussy, and she realized that the farmer was still hard. Maybe even harder than before. The humongous rod rose at an angle, looming over her noticeably swollen gut while a sticky string of pre dangled from the tip.

“Too fast? But it has been twenty minutes since we started warming up!” Rainbow grumbled. “And you can't complain about the quantity. I shoved in you so much cum that it looks like you swallowed a whole melon.”

As if wanting to prove her point, the irritated pegasus extracted her member from Applejack's tight cavity, and a copious stream of cum shot out of her, drenching the hay bale beneath her. Rainbow herself was a bit surprised at the amount; it looked even more than usual. All the more reason to brag about it!

“See?” Rainbow said as she smirked and pointed to the abundant cum stain. “More than enough to put a stud to shame.”

Applejack raised her back and touched her belly with one hand. She had already expelled most of the semen from the pegasus and her gut was returning to its usual shape.

"Well, that’s not too bad. However…" The farmer rubbed one of her huge balls with her hand. “I'm sure I could improve it.”

Rainbow started to think that she was hallucinating. Those beastly gonads looked even bigger. They must have been like cantaloupes, and she was sure they weren't so swollen when Applejack pulled her boxers down. Holy Luna… H-How much sperm are they producing? The pegasus was starting to drool just by thinking about it.

"O-Okay," Rainbow said as she sneakily tried to wipe her mouth with the back of her hand. “Then prove it.”

“Of course.” Applejack moved her hips to rock her monstrous cock like a giant metronome. Rainbow couldn't help but follow it with her gaze. “Yah wanna do the honors, sugarcube? Yah seemed to be very excited while you were touching me before.”

Rainbow snorted with conviction and quickly removed her tank top and her sports bra, exposing her modest breasts. She then sat down before Applejack's massive cock. As she caught it between her hands, the thick shaft throbbed and a thread of presemen sprouted from its tip, making a small arc and falling between her fingers and onto her already soaked member. It was so abundant that she bathed them completely.

"Goddesses…" Rainbow murmured to herself. “There’s so much…”

Applejack smirked as she tried to hold back a grunt of pleasure, but the gaze of the rapt pegasus was too fixed on the bronzed obelisk to notice her.

Without further ado, Rainbow began to move her hands to masturbate Applejack’s hot, slippery cock. The pre didn’t stop pouring in huge quantities. She then moved one hand to one of those colossal nuts, gently patting them. Fuck… They are so big that it’s hard to move them. The fragrance that emanated from Applejack’s sexual fluids was tempting her more and more, until she brought her muzzle to the plump glans and gave it a lick. It was bitter, salty and came with a touch of apple. She had never tasted anything so virile.

She couldn't wait any longer: she had to feel that immeasurable cock on her throat, so she opened her jaw and tried to insert the tip into her mouth. It was complicated, but finally, and after trying to reposition her head several times, the bestial glans managed to find its way between her two cheeks.

"Unnnggh!" Applejack tried to hold back her groans to no avail. “Good girl, yah're doing fine.” Then she put a hand on Rainbow's head. “But ah think yah're going to need a little help.”

The burly farmer pushed the pegasus' head down, managing to thrust four inches of her huge cock in one go. Rainbow was taken by surprise, but she tried to hold back her gagging reflex. Never in her life she had shoved something so tremendous down her throat. The pressure she felt was brutal, and the massive outline of Applejack’s gigantic rod was visibly marked on her neck. Rainbow took that member again between both hands and withdrew about three inches before going down again. She was moving slowly, picking up the pace while using her esophagus to jerk off her virile friend. Glllrk, grllrrk, gllrk. Each time she came down, she managed to gobble more cock, until she swallowed more than two-thirds of it. The pre, that hadn’t stopped oozing from the fertile member, was being inserted directly into Rainbow’s stomach, filling it non-stop.

"Ra-Rainbow!" Applejack announced urgently as she continued to hold her sucker's head. “Ah’m…! Ah'm going to cum!”

Applejack pressed down hard on Rainbow's head as she slammed the last third of her monstrous cock with an aggressive pelvic thrust. And then a monumental orgasm was unleashed. She fired her explosive volley of semen into her cavity. The volume was so overwhelming that the first shot was enough to make Rainbow's stomach overflow completely, spewing the rest of it out of the pegasus's nostrils. Applejack noticed her plight and released Rainbow's head. Once free, she pulled the gigantic cock out of her with one fell swoop, coughing and spitting copious cum out of her nose and mouth.

Applejack, meanwhile, continued to ejaculate in disproportionate amounts. A veritable geyser of semen flew three feet above Rainbow, falling like a cube of gelatinous, white silt on top of her. Thicker and thicker threads of cum shot from the tip, and the burly farmer directed each and every one of them against the stringy body of her friend. After a minute expelling what must have been gallons and gallons of semen, Applejack's massive shaft stopped her flow.

Rainbow, still hyperventilating from the sudden lack of air, put a hand on her face to wipe the seed out of her eyes. Hair, face, torso, wings, tail... her entire body was smeared with the whitish and powerful sexual fluids of the virile farmer. Applejack only had remains on her legs and her genitals, but the area two yards behind Rainbow was full of semen.

"Fu-fuck…" The pegasus was gaping, staring at all the mess Applejack's massive cumshots had caused. “How in Tartarus...?”

The stoic farmer was drenched in sweat, holding her cock while panting and showing a smug smile.

“How was that? Did yah like the demonstration?” Applejack held one of her balls with one hand. Their size hadn't diminished one iota to Rainbow Dash's surprise. “I have more where that came from, if yah want.”

The pegasus felt even more confused after having seen the incomparable sexual prowess of her friend. How was it possible that Applejack had lost the size bet and had not given a single complaint? That didn't make any sense! The farmer was a very competitive pony; she had already shown her many other times. She even seemed to be enjoying her defeat!

…

"You bitch," Rainbow blurted as she tried to wipe the semen off her body. “Now I understand everything. You wanted to lose to make a fool of me while I was taking the initiative. You had it all planned!”

Applejack laughed and kept showing her mischievous grin.

"Ah didn’t know for sure if ah was going to lose, but if ah had won ah would have enjoyed it, too," she explained. “But tell me, Dashie. Did yah like it? Because despite what you say, ah have seen you enjoy yourself like a pig in the mud.”

Rainbow gritted her teeth, then looked away angrily.

"You know I did," she muttered almost inaudibly.

How could she not enjoy it when her friend was so hot and she had such a enormous cock? She had what always looked for in a stud. No, she was even more than that. Rainbow thought that by winning the bet she was going to take control of the situation, but it was Applejack the one who took the reins without doing practically anything. The farm mare's body exuded so much sexuality that she was having a hard time not bowing down to her and letting her do whatever she wanted. But I was the one who won the bet, damn it!

"Well then, yah want more, right?" Applejack massaged her cock with her hand. She was totally stiff again. “Yah still have half an hour left.”

Rainbow realized that her own rod was also hard. Her pussy was totally soaked and she felt a familiar burning inside her. Her vagina was hungry for cock and thirsty for sperm. She needed to have Applejack's gigantic member inside her, for her friend to penetrate her savagely and permeate her insides with that thick cum until not even a drop could fit inside her.

"I… I…" Rainbow said through her teeth. “I-I want you to fuck me.”

Applejack put a hand behind her ear as she kept rubbing her colossal cock.

"Care to repeat, Dashie? Ah didn't hear yah.”

Fucking AJ.

"I want you to fuck me," Rainbow said, this time louder.

"Yah'll have to speak louder, girl."

"I said I want you to put your fucking cock in my fucking pussy!" Rainbow finally yelled.

The huge farmer smiled more smugly than at any other time that day.

"Oh, you'll have to do it yourself. The bet was…”

“No!” Rainbow interrupted with a squeak. “I-I don't care about the bet! I just want you to fuck me and I want it now, damn it!”

Applejack shook her head while still showing her mischievous grin.

But Rainbow couldn't take it anymore; she leaned against the barn wall and pushed her rainbow tail aside to present her firm, toned ass to her friend. A bright, thick thread of feminine nectar hung from her swollen pussy lips.

"P-Please." Her body trembled, filled with hunger and lust. “I ... I need it.”

Applejack held her chin between two fingers and let a few seconds pass.

"Well, if yah behave like a good girl ah might give yah what yah want."

She got up from her hay seat and walked over to her friend. Rainbow gawked, watching Applejack's huge cock and tits sway with every step she took towards her.

Once at her side, Applejack squeezed the pegasus's luscious buttocks with her hands, causing her to shiver and groan deeply. After stroking them a bit, Applejack put three fingers inside Rainbow's soaked pussy and began to stroke her slippery vaginal walls.

"Oo… ooOoOoh!" Rainbow moaned, louder than before. “Ce-Celestia!”

Those fingers danced and danced inside her, touching and caressing each and every one of her wet folds, until they left the wet tunnel and Applejack lifted them to her mouth.

"Mmmmh, delicious," said Applejack after sipping Rainbow's nectar. “You taste like a bitch wanting to be fucked.”

Next, Applejack put her huge member between the pegasus’ buttocks, and Rainbow winced at the contact. The warm, wet cock slid over and over again, smearing Rainbow with the powerful pre that covered the skin of her virile rod.

"Yah’re really wet, Dashie. Are you that eager to taste a real cock?” Applejack said slyly.

Suddenly, Rainbow heard a deafening snap and felt a burning pain in her right buttock.

"You gave me a good slap on the ass before, so I owed it to you." Applejack lifted her hand from the butt she had just smacked and slapped it again. “How about ah give yah some more, huh? Yah seem to like it.”

The pegasus closed her eyes, gritted her teeth, and moaned through her nostrils. With each slap she could feel a spark travel through her spine, more of joy than pain. Her pussy was getting wetter and hotter, until suddenly she felt a familiar, suffocating sensation deep inside her.

Rainbow arched her neck, let out a cry of pleasure and came on the farmer's thick cock, spattering it with her thick, slimy nectar. Her fluids trickled down their genitals, wetting the four heavy balls.

"I-I'm begging you, Applejack," Rainbow moaned, looking at her friend with teary eyes. “I-I need it now…”

The burly farmer kept rubbing her massive cock between Rainbow's buttocks for a few more seconds, until she finally pulled her pelvis away.

"Okay, I think you've waited long enough." Applejack took the huge tip of her cock and touched Rainbow's bottom lips with it.

With a slight push, the wide rod worked its way through the love tunnel of the whimpering Rainbow. The pressure she felt inside was immeasurable. There was so much cock that she thought she was going to break her in half, so she spread her legs to try and give her friend more room. Rainbow's mind was filled with ecstasy, delighting herself with every inch that huge cock penetrated inside her.

Applejack stopped when she noticed that her advance offered a lot of resistance.

“So disappointin’. Ah was only able to get a third in mah first lunge. But that’s fine;” Applejack gripped Rainbow's ass more firmly and spread her legs a little. “Yah’re gonna get all of it.”

Her cock came out a few inches from inside Rainbow and then came back in with more force. She repeated that over and over again, faster and faster, driving a few more inches into Rainbow’s pussy with each thrust. The brutal thickness of that rod made the penetration very difficult, but Applejack continued to piston firmly, determined to carry out what she had declared.

"Nnnghh… You're very tight, Dashie," Applejack commented while screwing her friend. “Ah was sure that you never tasted a cock as fat as mine, but ah was hoping that at least you had been fucked by one decent enough to loosen your pussy a bit.“

Rainbow was so focused on her pleasure that she could barely moan back. Applejack was right - she had never been penetrated with such a thick cock. In fact, Rainbow had fucked many ponies, some of them very large, but none came close to the behemoth she had inside of her at the time.

"Y-Yes!" Rainbow whimpered ecstatically. “N-No cock that ever fucked me is as *unnngh* fat as yours!”

Applejack's rod began to penetrate her with such force that she thought it was going to come out of her throat.

"Tell me how big it is compared to the ones that fucked you." Applejack slapped Rainbow's butt once more. “I bet they were small, right?”

"T-They were tiny! Like comparing *unnngh* foals with a real stallion!”

“Oh, yeah?” Applejack gave a particularly rough shove and managed to insert an extra inch of cock. “Tell me more.”

"Your… your balls are so fat! They're fucking wrecking balls compared to everyone else!” Rainbow continued. “Not even Big Mac has balls as big as yours!”

Applejack froze for a few seconds. She then pulled her beastly cock out of her friend until only the tip remained inside and then she thrust with all her might, penetrating Rainbow completely with a loud plap.

Rainbow arched her back and came copiously once more on the farmer's crotch with a piercing groan. Her abundant nectar again smeared Applejack's huge genitals, who continued to fuck her even harder. The pegasus watched as her friend's face took on a more serious and determined expression.

"And… And his cock is like *aaah* a fucking noodle!" Rainbow was being penetrated so savagely that she had to make force with her arms so that her head didn't hit the wall with each thrust. For the first time that day she was really feeling dominated by Applejack. “A little shit compared to your * uuugh * gigantic cock!”

Suddenly, the mammoth rod swelled inside Rainbow's cunt. She felt a huge bulge travel up her urethra, and then Applejack came like a fucking cannon. Each copious volley of cum was as abundant as a stud's entire orgasm. Rainbow's gut swelled more and more with the unimaginable amount of cum that Applejack's swollen balls were shooting into her.

Rainbow couldn't bear the tension and she came too with a piercing moan. The pegasus’ massive stallionhood shot its thick, copious cum against the barn wall, painting a huge white patch.

Even when Rainbow was done, the burly farmer was still at it. Her gut was already beginning to weigh too much from the exaggerated amount of cum it contained, until Applejack expelled the last drop from it and pulled her already flabby monster out of the vexed pegasus tunnel.

They both fell to the dirt floor of the barn, panting and drenched in sweat. Rainbow, lying on her side, put a hand on her hulking belly, as big as a beach ball. The jizz inside her began to drip in obscene amounts from her pussy from the moment Applejack’s cock was disengaged. When it stopped flowing, the huge pool of virile sperm on the ground was several yards in diameter.

“Holy fuck... Big Mac really cums a lot, but it’s like a shitty trickle compared to you. It’s a good thing that our cum is not fer- Auuch!” Rainbow felt a loud slap on her rear. She turned and glared at Applejack. “Quit it! You've already beaten my ass more than enough!”

Applejack, kneeling on the ground, pointed an accusing finger at Rainbow.

"You fucked mah brother and never told me anything!”

“So what? Big Mac is his own pony, you know? He can sleep with whoever he wants.“ Rainbow rubbed her flushed ass to ease her pain, then flashed Applejack a mischievous smile. “And anyways, you got really horny when I started talking about him, don't deny it.”

Applejack blushed and pouted as she avoided Rainbow's gaze, but it didn't take long for her to accept that her friend was right. In both things.

"Well, at least you seem to be okay," Applejack said with a sigh of relief. “Ah was unsure for a moment if ah wasn’t going too hard on you.”

"Naah, I'll be fine." Rainbow struggled to sit on the floor and gave a whining groan. “Well, I may be limping for a couple of days, but nothing this pony can't take. And anyways, I’m used to flying to move around, so it won’t be a big problem.”

"Ah didn't mean just that," Applejack said, scratching her head. “It’s mah... attitude. Ah can be very impulsive sometimes.”

"Baaah, nothing wrong with that." Rainbow waved her hand casually. “In fact, it was hot as Tartarus. I'm usually the one who gets aggressive while fucking, but you were truly awesome.”

"Well, Ah'm relieved to know." Applejack got up from the ground and looked around. “We need to get dressed and clean up this mess before someone comes here. Ah have a hose right outside.”

Rainbow didn't say anything and looked down for a moment. Seeing that she didn’t seem willing to move, Applejack became a bit concerned.

"Is something wrong, Rainbow?"

The pegasus snapped out of her thoughts and raised her head.

"No, it's just…" She hesitated for a few moments. “You think Big Mac won't mind that I have a bigger cock than his next time we fuck?”

"Rainbow Dash!"
