Date night

It wasn't too long ago that Applejack and Rainbow Dash had officially became an item. After a few months the farmer's and the ace flyer's relationship went from friendly rival to being quite the couple. Their friends didn't think much of the two being girlfriends. For the most part all of them had a close relationship so things never got to acquired among them. It was only in private that things got a bit more interesting. The couple had quite the sex life. Sometimes it would be the pegasus and earth pony in the tender embrace of one another and others times they would fall into their old habits and try to turn it into a contest of some sort.

Applejack had always admired Rainbow's loyalty and determination. How she always seemed to want to push herself beyond her own limits and managed to do so. But there was also a physical attraction too. Rainbow was one of the best flyers in Equestria and had a body to match. Her small 5'6" frame was made inertly of lean toned muscle that seemed cute to AJ. There wasn't an ounce of fat on her which aided in her goal of being the fastest. Her wing were strong and showed it with how developed and well maintained they were. There was also the fact that Applejack loved her flat chest that kept her so aerodynamic.

For Rainbow Dash she absolutely loved the body AJ had. Years of farm work has sculpted her body into a well toned masterpiece. Her legs were a prime example of how well she maintained her figure. Her perfect buns that they were attached to were no less impressive and Rainbow could eat them up like candy. The earth pony also had the most beautiful six-pack Rainbow has ever seen. Whenever AJ would tie her shirt up on a hot day the pegasus would just daydream of running her tongue all over thaws well defined edges that made up her belly.

But like most couples things are bound to get stale. After the couple talked about it they decided to ask for help from their friends. Pinkie suggested the use of whipped cream and chocolate to try and spice things up but AJ didn't approve of such a waist of food. The subject was a bit too sensitive for Fluttershy to talk about with her friends so she tried to avoid it. Rarity on the other hand was overjoyed to assist in this area. Unfortunately all her talk of tight leather, ball gags, chains, and riding crops scared the both of them. Surprisingly it was Twilight who was the most helpful with their problem. The princess claimed that she could make a potion that can give the two one of the best nights the two have ever had. It only took under an hour to brew and once the alicorn gave it to the couple, planes were made to meet in the barn of Sweet Apple Acres.

Night fall came as Rainbow Dash flew over the apple farm. The rainbow colored mare landed just in front of the large red building. She opened the barn door slowly to see that the building was warmly lighten by Candle light. Rainbow Dash saw that Applejack was waiting for her wearing nothing but a set of plain blue undergarments and her favorite hat. The magnificent body the peguses loved so much was on full display caused her wings to splay out uncontrollably. "So we have the whole place to our selves now don't we." Rainbow Dash said as she walked in and closed the door behind her.

"Eeyup." Applejack said as she walked slowly to her girlfriend. She wrapped her well toned arms around Rainbow's neck and leaned in for a kiss. A bright red blush overtook the pegasus’ face as she felt the farmer's tough wrestles her own in her mouth. After a few moments the two released each other and gazed lovingly into their eyes. "I told everyone to leave us alone so it's just going to be you and me all night." AJ said with a grin.

"Awesome." Rainbow said as she pulled away from her muscular girlfriend’s hug. "You get the potion while I get a bit more comfortable." AJ nodded as she went to retreated the poison from where she stashed it. In the meantime Rainbow started to take off her blue and white track suit. Once it was off she stood proudly in a black sports bra and briefs which clung tightly to her athletic build.

Applejack retrieved the potion which was a small bottle of pink liquid with a slight glow to it. The earth pony smirked as she saw Rainbow in her underwear and a cocky grin. "So Twilight told us that one of us need ta drink this stuff. So who's 'it gonna be." The two mares looked at each other without saying a word. In a flash they both held out their fists and shook them both three times.

"Once...Twice...Shoot!"

Applejack threw out of Rock while Rainbow threw out Scissors. AJ's grin grew larger as she handed the potion to Rainbow Dash. "Now drink up sugar cube."

The rainbow maned pony look worried was she stared at the bottle. She knew Twilight wouldn't have do anything to hurt her but she didn't know what this stuff was going to do. After a sigh that said "I lost fair and square" Rainbow Dash popped the cork off and pored the pink liquid down her throat. "Well it's not as awful as I thought it would be but that's not saying much." She said as she threw the empty bottle away.

"How ya feeling sugar?" AJ asked.

Before Rainbow could answer a warm sensation washed over her body. She grabbed her stomach as she began to sweat bullets. Her face turned a bright red as the sensation grew stronger. The pegasus soon relished that her briefs began to grow tighter and tighter as she panted heavily. Applejack's face turned just as red at the sight that was taking place before her. Rainbow's insides felt like they were on fire as she climaxed, liquids flowing down her legs as a huge cock and ball erupted from her vulva.

Both mares were more than shocked by the sight in front of them. To say Rainbow's new member was huge would have been an understatement. The thick cock spilled out of her underwear covered in love juice and hung a little over a foot between her legs. The huge set of balls she was sporting were no less impressive. Her underwear were barely able to hold the large sack along with rips that showed new cyan flesh. The pegasus was in shock by her new body part. "Oh my god, oh my god, oh my god! I have a cock, I have a fucking cock! How the fuck did this happen" she yelled.

"Now hold on there. This must be what that there potion dose." Applejack said as she kneeled down to take a closer look at Rainbow Dash's new third leg. Just her touch alone was enough to send chills down Rainbow's spine. AJ snickered as she held the appendage in her hand. "Ya know between your flat chest and ya new downstairs addition I'd swear ya was a boy."

"HEY!" Rainbow yelled in defense.

"Aw hush now, ya know I love them flat as a bored." AJ replied. She was still very amazed at the large cyan rod she held in her hand. The serpent started grow longer and harder as Rainbow's face grew more red. Applejack licked her lips as she leaned in closer. "Why don't we take the little old thing for a spin now." Before Rainbow could give a response the earth pony took the beast and shoved it into her mouth. Muffled moans of pleasure came from the earth pony.

"AJ what are you...OHHHHHHHHH." Rainbow Dash was unable to finish her thought as her body took over on its own. A wave of pleasure washed over her body as her cock began to grow in her partner's mouth. Applejack's head was pushed back as the rod began to overflow into her through. All the while the farmer was sucking Rainbow's new cock like an ice-pop on a hot day. Trying to keep her mouth's grip on the appendage, AJ garbed the ass of her lovers it's both hands. "You really know what you're doing down there."

After only five minutes of Applejack's strong tongue wrapping around the massive thing Rainbow erupted in an explosion of ecstasy. As Rainbow orgasmed another effect of the potion started to kick in. Every muscle on her body started to grow. Her arms bursted into huge Pythons. Her shoulders broadened to support the new bulk she was growing. The change wasn't only in her arms as her bee sting breasts started to inflate to the size of apples. Her abs which were already impressive for a mare grew harder and even more defined. Her thighs blew up with feminine power to support the new bigger muscles she were growing. She even grew a bit taller too stopping at a even 6 feet. The new mass that was being added was now stretching what little clothing she had left to their limits. AJ keep the cock in her mouth to make sure that she got every drop her girlfriend had to offer.

Due to how far Rainbow's members was down AJ's through almost all of the cum that was stored in her newly formed balls emptied into AJ's belly. The white creamy fluid she was consuming was also having an effect on her as well. It was slow as Applejack started to add more bulk to her already muscular body. Biceps bulged as the magic infused cream flowed into her gullet like hot apple cider on a cold winter's day. Veins rose to the surface was the farm girl's muscle mass grew to almost the size of her older brother's. The straps of her bra snapped as her breasts grew freely to the size of cantaloupes and going even further than that. All the changes she was going threw went unnoticed as Applejack was lost in the the sweet flavor of the cum consuming it in pints.

After Applejack was finished she pulled back and whipped any leftover fluids off her face. "Wow, now that was a rush." The farmer said as she stood up to her new full height. Unaware of her growth Applejack looked at Rainbow Dash with amazement of her own growth. "Holy cow! You look like you really bulked up there Dashy." AJ said as she got aroused by the new muscles her "little" girlfriend was now sporting.

Rainbow looked down to see that she became quite the beefcake. She raised her right arm and flexed. Sure enough the arm erupted with an amazing bulge. She felt the power continue to flow threw her body. She then flex all the muscles on her body which made her appear even bigger. In an instant whatever clothes that still clung to her body was blown off leaving her magnificent body on full display. Even the massive beast between her lag grew, hanging only a few inches above the ground. She turned her attention from her muscles to her new breasts. Both of Rainbow Dash's hands moved to cup her new C-cup boobs. A feeling of pride came over her as she was no longer a flat chested runt. "Oh yeah I can really get use to this." She said with a cocky grin.

When the flyer glanced up at Applejack she saw a sight that made her member become fully erected within seconds. She stood like a Titan with both hands on her wide hips at what Rainbow Dash can assume was 7'6" with enough muscle that made her brother look like a skinny butterfly. Her breasts were enormous as they were free of any restraints. The humble pair of panties she had was now stretched into a thong that looked like it was ready to snap at any moment. There was layers of muscles packed all over her body that only caused Rainbow Dash grow even more aroused as she inspected her. "All that protein I swallowed must have had some magic in it. Figures since that shotgun you got was made with magic too"

"Holy crap you look so hot!" Rainbow yelled with her tongue hanging out. She held her hands up with his finger moving completely on their own. "You're a real mountain of a woman now AJ, and I want to conquer you."

Applejack grinned ."With how big you are I think you just might be able to." She came up to Rainbow Dash, taking in just how big she grew. Thaw she did said that she loved her lean and athletic build she started to believe that the blue mare was even sexier packed with all the meat on her bones. She ran her hand down her girlfriend's mighty cock and felt just how powerful it was. The farmer could feel her partner's pulse which was racing. "Ready for round two?"

"Oh yeah! But this time enough with the warm up." Rainbow said

"What do you mean?" AJ asked

Rainbow just grinned. "Take the thong off and sped them." The pegasus' voice was demanding. Under normal circumstances AJ would have broken Rainbow's wings but she knew it was all the heat of the moment. The farmer turned around and mover her blond tail out of the way to show off the glorious ass she possessed. An ass that was made even more glorious dew to all the muscle she gained. Rainbow could barely contain herself as AJ slowly grabbed her underwear and pull them down her mighty tree trunk legs. Once they were completely off her she spun the garment around her finger and threw them to the side. "Looks like this cowgirl is ready for the rodeo." Rainbow said playfully.

Applejack slowly walked to her lover with bedroom eye. Rainbow sat back in a pile of hay as the farmer stood tall over her. The massive cock the flyer sported came to just below AJ's breasts. "You do know I'm a rodeo champion? There an't a bull in Equestria that can beat me." She said as she took the cock with one hand.

"Ha, Thaws bulls don't have anything on me." Rainbow said. "You better hold onto your hat cause that first time was just a warm up. This thing is ready to really blow this time"

"Good cause I plain on both of us to grow huge." Applejack said. She took the large member and slowly worked it into her marehood. Loud moans came from both mares as the large shaft plunged deeper. Love juices poured out from AJ's volva as waves upon waves of pleasure washed over her body. Rainbow's large cock filled every inch of her insides. A cock of that size would split a normal mare in two but at the moment Applejack wasn't a normal mare. Her tongue hung out as her took in every inch the mare had to offer. AJ was lost in pleasure alas the two mare's body's were as close as physically possible. There was a sizable lump on AJ's belly showing how much space Rainbow's member took up inside her.

Rainbow was also the enjoyment of her lover. She felt her new appendage being squeezed tightly by Applejack's musclier pussy. The earth pony slowly worked the massive rod in and out, having to grab Rainbow's new tits for support. The pace started to become faster as a rush of pre started to fill the insides of Applejack. Before her eyes the flyer started grow again. Her muscles inflated like a balloon becoming even more defined than before. Veins were pushed to the surface to bring blood to the new muscles she now had. Her breasts as well were pushing against AJ's grip. She was starting to catch up to AJ in size as she started to climax.

The rush of cum was much more powerful this time due to how much stronger Rainbow Dash was now. The release of cum almost cause Applejack to lift off like a rocket. Through sheer will power and crotch strength she managed to stay where she was. She took everything her lover had to offer, inflating her belly like a cream filled balloon on the brink of popping. Ones the pegasus unloaded all the cum that was left in her balls, Rainbow pulled out with small white drops coming from both of them. After a few seconds the large belly that Applejack had gained begun to disappear. All the mass she gained started to go to the rest of her body. The protein and magic bulked her up even more than she already was. If she was a titan before she's a goddess now. Her arms that look like she could lift a house with one hand and her legs were thicker than tree trunks. AJ's breasts were now double there size but with how strong the rest of her body was the addition weight was nothing.

"That-that was amazing." Applejack Jack said as she wiped the sweat off her forehead.

"You said it." Rainbow replied. She lied back on the pile of hay with her legs spared to allowing more room for her massive cock. Applejack lied down next to her. She put her huge arm over her shoulder and grabbed one of Rainbow's mighty E-cups. Rainbow let out a small gasp before smile. "Ya know I can really get use to this. I mean the cock will be a real adjustment but if it means we look this sexy it's worth it."

AJ grinned. "Well Twilight said we'd be back to normal in a few hours." She said as she kissed her girlfriend on the lips. "But I'm glad you're likening being this big too."

Rainbow nuzzled her head on her much larger partner's breasts and smiled. "Well till we Shrink back to normal, why don't I rock you till you're big enough to pick up the whole town on your own." Applejack couldn't help but laugh at what Rainbow said. The image of her as a huge muscle bound giant was ridiculous to her but if it meant having Rainbow's massive shaft inside her she guess she be willing to try.
