"Come on, just one more and your done sweaty buns!" Fleetfoot yelled out, as she held her hand on Rainbow Dash's back.

    Rainbow was drenched in sweat as she strained to pull herself up for one last push-up.

    The drilling Pegasus licked her lips and enjoyed seeing her fellow Wonderbolt sweat like a pig. "Come on! Move your hot sweaty ass, Crash!"

    Rainbow was rather weirded out by the comment, but snapped out of her confusion and took one last breath before pushing upwards. The sky blue Pegasus finally made it to her hundredth push-up, exhaling with a loud "AH" and dropped to the floor. "I hate working out!" Rainbow cried as she tried to catch her breath.

    Fleetfoot tilted her head at her. "Then why do you do it?"

    Rainbow dash pulled herself on onto her hooves and rubbed her arms before answering. "Simple.." She paused while walking over to the table to grab her water bottle. The Pegasus then started to chug down a few swallows, before stopping to finish what she had said. "I got to keep this fine ass in shape for Soarin." Dash commented, while smacking her huge ass. As she did, her flank jiggled like jello while Fleetfoot was hypnotized by it shaking.

    Rainbow was known for two things in the Wonderbolts. The first was being the fastest and by far the best Wonderbolt in history, while the second was her huge melon sized ass. While she lacked a bust, only having a B cup, she made up for it in the thighs and butt department. No Wonderbolt had a flank like her's, and every Stallion -along with some mares- loved looking at it. She was by far proud of both and did not mind showing it off to anypony.

    Fleetfoot raise a brow as she was confused. "So.. you do it for a stallion?"

    "No.. I just do it, because he loves this nice ass and I want to stay in shape." Dash stretched with a forced grin, hiding the fact that she did not know how Soarin would feel if she gained weight. Even though the two have been going out for over a year, she didn't know if she could just let herself go like she would want to. There was no negative consequences for being fat, due to pegasi's wings and unicorn horns working on magic, which meant she would still be the fastest flyer and maintain her Wonderbolt duties.

    Fleetfoot shook her head and sighed. "Okay, if you say so," she muttered, before grinning at Dash. "You, um want me to wash your sweaty work out clothes? I don't mind."

    Dash looked at her with blank eyes. "Um.. its ok, I have a washer at my house." she responded. She didn't mind the gesture, but she could do it herself.

    Fleetfoot didn't persist. "Okay, if you insist. I gotta go home anyway."

    "OK, well I have to get home and get ready for my date with Soarin tonight," Dash said, while grabbing her towel and wiped the sweat off her face.

    "So where is he taking ya?" Fleetfoot asked, walking over to grab her own towel.

    Dash shrugged. "Not sure, he wants it to be a surprise."

    "Maybe he'll take you to the race in Canterlot today?" Fleetfoot mentioned as she and Rainbow Dash walked out of the gym.

    Rainbow replied with 'maybe' as the two mares said they fair wells. Dash watched her friend fly off before walking toward her home.

    While Rainbow was walking, the mare looked up into the sky, enjoying the bright sunny day that the Pegasus had made for Ponyville. However, Dash was not paying attention to what was in front of her, and soon found herself face first in a pair of huge breasts. As the mare blushed in embarrassment, she quickly jerked her head back and apologized. She was hoping she didn't come off as a pervert to who ever her face slammed into. She saw that the pair of JJJ tits belonged to none other then her very skimpy outfit wearing friend, Pinkie Pie, who was just smiling and giggle with no shame what so ever.

    Pinkie tugged at her assets with a chuckle that only emphasized their size. "Tee hee, Dash, did your face want to tell my boobies hello?"

    "What?... no my face doesn't...your boobs where just in my face's way." Dash rubbed her arm with a nervous touch, before shaking her head. "Wait...why are you just standing here anyway?"

    "Oh simple, I was wondering if you'd like to eat a ton of pie?" Pinkie said as casually as one could for such an outlandish invitation.

    "Mmm.. sorry, Pinkie. I gotta pass," Dash replied, while rubbing her stomach. "I can't eat any sweets."

    The pink busty mare's expression soon turned into disappointment. "Aw... ok, I understand. I mean, it was a pie eating contest, where you will be winning a gold trophy and stuff."

    Rainbow's mind went blank as her eyes widen at the words 'competition' and 'winning.' Her heart started beating faster at the idea of stuffing her face with pie, standing on a golden throne, with bits raining down from the sky, everypony chanting her name, while wearing a gold crown and holding a pie staff. It was a glorious thought.

    "Dashie?... Dashie?... DASHIE!" Pinkie yelled, trying to get her friend's attention.

    Dash soon snapped out of her trance and looked back at Pinkie Pie. "Oh sorry Pinkie..." The rainbow-maned pony thought about her decision. Rainbow knew that if she took this challenge, she would risk getting fat, but at the same time, she wanted to win. Dash didn't mind being fat. As a matter of fact, she really was staying in shape for Soarin. If it was up to her, she would just lay back and feed all she wanted. But she didn't know how her lover would react, and was kinda embarrassed to ask.

    After a few seconds, she thought heavily about her choice and smiled. "Yeah... I'll join the eating competition. I have a reputation to hold." Rainbow said with a smug look.

    Pinkie soon smiled and giggled. "YAY! I knew you would say yes. I mean you are the pony that said yes to that thing with the Yaks, which made you smell funny for a whole month." She squeed, before grabbing Rainbow's hand. "Lets go, we got five minutes before it begins."

    Rainbow soon found herself flying off the ground, while Pinkie ran with her. Everything was a blur as she saw the houses just flash bye in Pinkie speed. Rainbow was soon in a daze, probably due to her eyes spinning in her head. After just a few seconds, Pinkie and Dash burst through the door way.

    The hyper pink mare sat Rainbow down in a chair next to the other ponies who were in the competition. She then ran upstairs in a blur to get ready in the three minutes they had left before the game.

    As Rainbow was placed in her seat, she came back from the daze she was in. She took the time to look around to view her competition. Beside Rainbow was a very masculine Big Mac, who was in a muscle shirt that exposed the perks of working at an apple farm all day. "Hey, Big Mac. You ready for the competition too, huh?" Dash asked.

    The strong stallion nodded with a mighty "Eeyup."

    "I'm ready too!" Said a very thin and frail Pip Squeak, who was peering over at Big Mac. Rainbow just grinned, for she knew he would not be a threat.

    Dash soon smelled pot, and turned around to see Tree Hugger sitting beside her. The hippie pony was just chilling there, and looking at her own hand as if there was something there. She seemed to be in a trance just looking at it.

    However, Rainbow's eye caught a very large pony sitting beside Hugger. She turned her attention to who it was, only for her jaw to drop. She saw the sweat glisten off of the pony's gut. I could've been about the size of herself. Draped over the meaty rolls of her were pillars of cellulite filled thighs that flooded the pony's seat. Rainbow could practically hear the gurgling of digestive noises and heavy grunts she assumed was breathing that exited the mare's body. Mint green piles of corpulence gave Rainbow all the hints she needed.

    It was Lyra.

    Of course, next to the obese mare was Bon Bon. Unsurprisingly, her hands were seemingly glued onto Lyra's mountain of flesh in front of her. Her mate's hands were lost in her massive horizon of Lyra's gut that split her top and bottom belly. Much sweat and possibly even bacteria was kneaded into Lyra's massive crease and cavernous belly hole. The two lovers gazed into each other's eyes as they kissed.

    Rainbow could not help but be envious of the two. She wanted that to be her and Soarin. However, her thoughts were soon cut off as the lights turned off for five seconds. As the lights came on, everypony saw approximately fifty pies before them. The smell made both Lyra and Rainbow drool in hunger.

    Pinkie soon popped out of nowhere, wearing a skimpy cheerleader outfit. "Are you ready to show down?"

    "I sure am Ms. Pinkie." Pip Squeak said with so much enthusiasm.

    "Eyup." Big Mac responded while cracking his neck and knuckles.

    "Yeah dude...I am like..so hungry I could eat a Yak..." Tree added.

    Bon Bon kissed Lyra's greasy cheek and smile "Well, my fatty can eat the Dragon King himself," She commented as she patted her fat lover's belly.

    Lyra blushed and as she kissed Bon Bon back. "Mmm, yeah this pie really looks good. I can't wait to stuff my face hehe."

    Pinkie smiled "Okie dokie, here are the rules. You are to eat ALL the pies, whoever eats all, or the most wins. If you can't go on, just ring the bell to tap out. Got it?" She asked.

    Everypony nodded in agreement.

    "Ok, Ready... set.. CHOW DOWN!" Once Pinkie gave the 'go', everypony started stuffing their faces with sweet apple pie. Granted, there was also cherry, pumpkin, and other types of pie. But for Rainbow, it was all pure heaven, as she stuffed her face and enjoyed the delicious taste of the bake goods. Dash ate, and her mind started to wander a bit. She thought about lying in a huge bed, while Soarin fed her many of her favorite foods. She was super obese, with rolls of glorious fat. Dash, thought about Soarin rubbing her belly, just like Bon Bon does for Lyra. Rainbow wanted so badly to have what Lyra and Bon Bon had. No, she craved such a feeling.

    As time went on, and everypony was consuming pies, a bell rang. It was Pip, who was holding his stomach, with a half plate of pie before him. "ehhh... I'm full..." He whined, as he only had half a pie.

    "Okay, Pip is out. Only Dashie, Mac, and Lyra left." Pinkie cheered.

    Rainbow Dash was busy swallowing the mouthful of pie when she heard the news. She was happy to hear one less opponent to worry about. However, she knew the other three were going to be trouble. Mac was known to eat a boat load of apples after a hard day's work, while Lyra's fat stomach and apatite could eat a weeks worth of food in one sitting. Also, Tree Hugger was high as hell, and due to having the major munchies she had just as much of a chance to win.

    But, she didn't let that stop her from eating like a hog from hell. After a while, Big Mac rang his bell just after eating 33 plates of pies. It was then down to her, Tree, and Lyra. however, she soon heard noise from her right side. She stuck a slice of pie into her messy mouth and looked to see Tree was snoozing with a bloated tummy.

    Pinkie hunked the horn twice. "Tree Hugger and Big Mac are out!" she called as she jumped up and down with with pom poms.

    It was then just her and Lyra. "Go on baby, you can win!" Bon Bon cheered for her lover.

    Rainbow looked over to see how many pies were left for Lyra, only to be shocked to see only three left, to her four. Dash knew if she wanted to win this, she had to go into fifth gear. So the Pegasus started cramming pie into her mouth before finishing the plate. She then discarded the tin and snatched the next one. She just planted her face into it and gulped the pie down like a vacuum. She did not care about getting the sticky and warm sweetness of the pie over her face. As she hurried up eating, her stomach started to get tighter and tighter as she swallowed bite after bite. However, after she started going down on her last pie, the bell soon rang. Rainbow froze up, as she knew what that signaled. "Crap....no."

    "Aaand, Lyra wins!" Pinkie screamed as confedii popped out between her jugs and balloons fell from the ceiling.

    Bon Bon screamed in delight as Lyra wiped the sweat from her forehead.

    Pinkie then skipped over to give Lyra the golden pie trophy. "Congrates!" Pinkie exclaimed.

    Lyra thanked her and went to kissing Bon Bon again with her breath filled with the sugary scent of pies.

    Pinkie then looked back over to Rainbow and saw the look of defeat on her friend's face. The pink mare then walked over and hugged her friend top comfort her. "Cheer up Rainbow, you still won second."

    Rainbow smile weakly and sighed, her voice dropping to a mumble. "Yeah...I did." She got up with a bit of effort with a stomach filled to the brim of pastries. Rainbow was rather disappointing in losing, because she really wanted to win. However, Dash was still a good sport, and walked over to Lyra to shake her hand. "Hey, that was fun, congrats. I really thought I would win there." The mare smiled.

    Lyra took her tongue out of Bon Bon's mouth to look at Rainbow and smiled back. "Thanks, and maybe. I would love to have another pony to be a good rival with."

    Dash tilted her head. "What do you mean?"

    "My Lyra is not only the fattest pony in ponyville, but nopony can match her hoggish hunger." Bon Bon commented with a stifled burp from Lyra that left crumbs of pie crust on her double chin.

    Lyra blushed. "Yeah, I would love to have another fat pony to compete with."

    Dash laughed shortly. "Well, maybe I will get fat too.." she said out of nowhere. Dash realized she just blurted that out.

    Both Lyra and Bon Bon's face lit up. "That would be wonderful!" Bon Bon beamed.

    Pinkie butted in with a hop."Yeah Dashie, I am sure Soarin would love a Rainblob hehehe."

    Dash thought to herself for a second without saying anything. "Yeah...hey I gotta go. I got a date with Soarin tonight anyway."  

    Lyra, Bon Bon, and Pinkie waved bye to Rainbow as she walked out and flew back home.

    She walked into her cloud castle, while rubbing her belly. Her stomach ached as she went in and laid on her bed. She soon drifted off to sleep, completely forgetting the time.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    "Oh no, oh no!" Rainbow screamed, as she woke up and felt her pants, along with her shirt feeling really tight. She jumped up and looked down to see her fat belly jiggle. Dash seemed to have gained a bit from all the food. Her eyes darted to the mirror and looked in horror at the sight. Rainbow could not believe her eyes. Due to all those pies she had eaten, her body had grown a lot. Her shorts had unbuttoned and were pushed out by her blue pot belly. Her body had been coated in fat, leaving her muscle tone hidden by the effects of her earlier gluttony. Her already well shaped ass had now gotten the same treatment as she squeezed the now soft fat. She never thought it could ever get more enticing.

    Dash also recalled that Pinkie's pies are not your typical sweets, but magical high fattening bake goods that Bon Bon apparently had asked her to make just for Lyra. She became terrified about what Soarin would think. Rainbow, then thought about what she should do before the date, which was in an hour and a half. She could have asked Twilight or Starlight, but they went to appaloosa with AJ and the unicorns here didn't have any weight lost magic. As Dash paced the floor, she realized that she could ask Fleetfoot for help. She had no idea on how or what the Wonderbolt could offer, but anything was good at the moment.

    Rainbow ran out of her house and flew off to see Fleetfoot. After thirty minutes, Dash arrived at the Wonderbolt's home. Fleetfoot was watering her flowers on her lawn, while still wearing her sweaty gym outfit from the following morning. the rainbow maned pegasus flew down to meet her.

    "Fleetfoot!" She called out.

    The still sweaty Pegasus, stopped watering her daisies to look behind her and Dash landing on her lawn. The wonderbolt's eyes widen in shock as she was speechless to see Rainbow had gotten... well fat. "R-Rainbow...what happened?"

    "I ate a whole bunch of pies, and now I got fat...can you please help me?" Rainbow asked in a rush of words.

    Fleetfoot, taken back by the sudden intrusion of her teammate, looked at Rainbow with concerned eyes. "Help...? why?"

    "Because I have no idea what Soarin is gonna say to this." Rainbow said.

    Fleetfoot chuckled a bit. "Dash... Soarin loves fat mares. In fact, he wanted you to be fat, but didn't know how you would react."

    Dash's face went from panic to totally annoyed. "Wait... we been busting our asses for no reason And you could have told me Soarin loves fat mares?"

    Fleetfoot twiddled her thumbs guiltily. "Yeah..."

    Dash put her hands on her wider hips. "Then why in Celestia's name didn't you?"

    "Simple... I like watching mares sweat.. its kinda my thing." Fleetfoot resplied with a blush.

    Dash wanted to tell Fleetfoot off, but knew she couldn't. Her date was getting closer. She spread her wings and jet off back home, without even saying a word to Fleetfoot.

    "Hey! can we still work out together?" Fleetfoot yelled out, but it was in vain. Dash was out of reach. Fleetfoot just shrugged and went back to watering her flowers. "Mmm.. I wonder if Spitfire wants to sweat with me?"

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

    As soon as Dash got back home she screamed in delight. This was her dream. So, the mare ripped her tight clothes off and went to lay in her bed. She pulled the covers over her, to hide her breasts, for she had a very hot idea for what Soarin and her could do tonight.

    The clock soon struck 6:00P.M, and came a knock at the door. "Come in," Rainbow said in a seductive tone.

    The door opened and in came a very tight, muscular Soarin with a bouquet of flowers. "Um, hey Dash, sorry I didn't really have plans tonight. I mean, I know your not the type of mare who likes fancy dinner and stuff." Soarin said nervously.

    "Oh, its ok Soarin. I got an idea, come in my room." Rainbow replied.

    Soarin soon got a little hot under the collar at the suggestion and walked toward Rainbow's room. As the stallion opened the door, his jaw dropped at the sight of Dash. The figure of her nude and only had her silk covers covering up left him in a stuttering mess. "D-Dash...have you...um.."

    "Gained weight? Yeah..." Rainbow purred while patting her silk laden belly. "Fleetfoot told me about your love for fat mares, and I have a love for getting fat. So, I thought... maybe you could help?"

    "H-help? You.. you really love being fat?" Soarin questioned.

    Rainbow nodded. "Yes, so are you going to feed me or not?"

    Soarin grinned and put the flowers on the dresser "Yeah.. but what am I to feed you?"

    Once Soarin had asked that question, there was another knock at the door.

     "Come in Fluttershy." Rainbow called with a smirk.

     Soarin looked at the chubby mare confused.

    However, Fluttershy soon came in with a cart full of apple pies. "Um.. here you go Dash.." Fluttershy whispered from her thin, white scarf. "Pinkie, asked me to give you all these pies, telling me something about you calling her and having 'plans' with Soarin," She explained with a burning blush that streaked her creamy cheeks. Fluttershy also had noticed that her friend had put on some pounds, but did not want to ask her, due to not wanting to hurt Rainbow's feelings.

    "Thanks, Shy. You can go now please," The rainbow Pegasus stated.

Fluttershy nodded weakly before shuffling off. Rainbow grabbed a pie and yanked the sheets off, revealing her naked body. "Ok, you ready to fatten me up?" she asked with a grin.

    Soarin felt himself stiffen down below in his pants. He nodded and walked over to Dash. He grabbed the pie and placed it into her mouth.

    Dash slowly wrapped her mouth around the slice, savoring the taste and warmth of the pie, before biting down and chewing. She closed her eyes as she enjoyed the flavor of the baked good.

    Soarin then rubbed her small belly while feeding her more slices.

    The mare just laid there in total bliss. She had finally gotten what she wanted, no more did she have to sweat at the gym and be concerned with her figure. Rainbow just kept eating slice after slice, while Soarin played with her belly.

     "Good girl Dash, eat up," Soarin said coyly.

    Rainbow felt the fat between her thick thighs dampen to her lust. He let out a moan of pleasure each time Soarin fed her a slice. She would open her lidded eyes to see Soarin smiling at her as she was being fed. Dash was soon in a trance and did not want to be broken out of it. She was to be fed by her lover and nopony can take that away from her.

    Soarin soon slid his fingers down Dash's belly, and started playing with her plump and wet clit. This in turn made her blush as she swallowed the pie. Once Soarin slid the slice down her throat, he was about to pull back, until Dash grabbed his hand and sucked on his sticky fingers. As the fat mare sucked, she felt herself getting light headed and close to her climax. Soon she let out a huge moan of lust, as she came all over Soarin's hand. Rainbow giggled dreamily as sleep tried to take her chubby, still eating the bake good that were made just for her. Dash had some how managed to sleep eat. And she ate them all.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------\\

    Rainbow Dash woke up the next morning, feeling a lot heavier then last night. She also felt Soarin sleeping on top of her newly grown belly. Dash had looked down to see what her hard work had accomplished. Her blanket of blue, creamy fat spread like butter over her thighs. She enjoyed the feeling of each roll and smiled. The fat Pegasus was at her best and she couldn't have been happier. As she squeed in delight, Soarin woke up with a yawn. "Hey Dash, good morning." She groaned as he kissed her belly.

She giggled and pressed her boyfriend's head in her plush midsection. "Morning."

    "You seem happy." Soarin smiled.

    "I am! No longer do I have to work out or anything." Dash said gleefully as she felt his grab a handful of one of her blue, pillowy asscheeks.

He dug into the crevice that hid her moist privates, which took his entire arm to wrap around such a beast. He felt her pucker rumble in response to his teasing. He sniffed her flatulence with gusto, taking the new experience. Still, more important matters were at hand. "Yeah, so you wanna eat breakfast?"

Before Dash responded, she remember one thing. Something she wanted to do something really important.
