Private Training with Dashie

 

You pushed open the door to your bedroom a crack, only for Rainbow Dash to slam it shut. “Hey...I've got an idea...lets forget the pool and just grill burgers. It might rain soon, anyway.”

 

The sky was clear as could be. Beautiful blue sky for miles around. “Did you lose your swimsuit or something? We could always just swim nude if you want.” You teased

 

“I'm not in the mood to swim today. Just forget it.”

 

Something was up. Rainbow Dash never turned down a day to chill at your backyard pool. You tried the door again but her weight kept it closed.

 

“Fine...Guess I'm swimming by myself.” A few stomps through the house got you close enough to open the back door. You slammed it shut, then quietly returned to the bedroom door, careful not to make a sound.

 

Rainbow Dash waited....and waited....and waited. A sigh fell from her mouth as she walked away from the door. You could hear her grumbling to herself before another heavy sigh. “Jeez...I had no idea it was this bad...”

 

Curiosity peaked, you pushed open the door and rushed inside. Rainbow Dash was sitting on the bed in her two piece bikini with a slight blush on her face as her hands were pinching at her body. She turned around as the bedroom door opened, rushing to cover her body as you walked in. “HEY! YOU LIAR!” She shouted at you, her face growing deep red as she scrambled to hide under a blanket.

 

“Dash, what's wrong? What are you trying to hide?” You tried to approach the bed but the shy gal slid under the covers.

 

“Go away...I'm so embarrassed that I think I'm gonna die.”

 

Rolling your eyes, you sat on the bed next to her. “Oh come on. What is there to be embarrassed about? If you need a new bikini or something, we can go somewhere and get you one super quick.”

 

“No...my bikini is fine!” Rainbow Dash insisted.

 

“Well, what's the problem. I can't help you fix it if you don't tell me.”

 

Rainbow Dash squirmed under the covers for a moment before slowly revealing her head. “You promise not to laugh?”

 

“I promise.” You reassured her with a smile.

 

“You better not!” She puffed out her cheeks as more of the blanket was pulled away. Her blush returned as Rainbow Dash revealed her body. Her arms crossed under her chest as she looked away. “See?”

 

At first glance, nothing really seemed to be wrong. All you saw was your sexy girlfriend in her bikini. You struggled to find any flaws until you realized just how tight the bikini seemed to be. Her breasts struggled to hide under the thin straps, the edges of her pink areolae exposed as she tugged at her top.

 

Her thighs were touching together, flab squished together as she kept her body rigid. The straps of her bottoms struggled to reach over her impressive hips as they drastically flared out. She was still the same goofy, fun loving girl you had fallen for, but her body seemed just a little thicker in all the right places.

 

“Did your bikini shrink or something?” You asked

 

“You know it didn't” Rainbow Dash rolled her eyes as she tried to hide herself as best she could

 

“Oh....well, we'll get you a new bikini. Simple as that.”

 

“I don't WANT a new bikini!” Rainbow Dash blushed harder as she struggled to adjust her swimsuit. “I want to fit into this one!”

 

You shook your head. “Not happening, at least not today. We can buy a new one for now and when you slim down, give the bigger one away.”

 

“Bleh, no way. Buying a new size is admitting defeat.” Rainbow Dash sighed as she got up and looked at the mirror. “How did I let myself go like this?”

 

Her ass jiggled with every step, making you bite your lip as you struggled not to say anything. Rainbow Dash resumed her inspection of her body, pinching her thighs, jiggling her tits and poking at her thick booty. There was nothing you could do to hide the growing erection in your thin swim trunks as Rainbow Dash gave you one hell of a show.

 

“Too many lazy days and not enough running.” You licked your lips as Rainbow Dash tried to fish her panties out of her crack. “We could always cut your diet and get back to cardio every day.”

 

“Yea, I know...Tomorrow for sure.” Rainbow Dash turned around, her eyes widening as she spotted your growing bulge. “Wha....Were you staring at me??”

 

“Well....yea?” It was your turn to blush as your hands darted in front of your crotch.

 

“Jeez, you are such a pervert.” Rainbow Dash sat down, letting her butt squish into the mattress. “Staring at my gross butt like that...”

 

“Hey, it's not gross!” You exclaimed. “It's a perfectly fine butt and I love it.”

 

“No way! I'm all disproportionate like this. I'm not the slim athlete I was a couple months ago.”

 

“But you're still the same Rainbow Dash to me.” You inched yourself closer and pecked her on the cheek. “I just want to spend a day with my cutie by the pool, chubby or not. Can't we have this fun day for ourselves?”

 

Rainbow Dash blushed as your sappy words filled her ears. “Fiiiinnnne. We can chill by the pool.” She stood up and led the way, blushing as your eyes were focused on her fat ass.

 

You busied yourself with setting up a few snacks while Rainbow Dash sat by the pool. She slumped into her deck chair and blushed as she noticed how much breast flesh blocked her vision. “No way these things are sexy...” She growled before getting up and sitting down at the edge of the pool Rainbow Dash dunked her legs into the water and stared at the calm skies above.

 

“Aw, that's not relaxing by the pool.” You frowned as you sat down beside her. “Does being a bit bigger really upset you this much?”

 

“I'm supposed to be an athlete. Trim and in shape. Now I look like a total cow.” Rainbow Dash shifted her weight for a moment, blushing as she noticed how much her fat cheeks squished against the concrete.

 

You pulled her in for a small hug. “Now now, no need to be so harsh on yourself. We can do some workouts in the water if you want.”

 

“I mean...I guess we could.” Rainbow Dash slipped into the pool and waded in till she was waist deep in the water. You followed her in and moved along with her, doing your best not to stare as her tits struggled to break free of her skimpy bikini top.

 

No matter how hard you worked, Rainbow Dash only seemed to give a halfhearted effort. Her eyes were constantly on you, noticing every moment you were staring. “You know what, forget it. I'm going inside.”

 

“Dash, please!” You reached out and grabbed her arm. “No one is judging you but yourself. If I don't care, why should you?”

 

“You're just saying that. You can't keep your eyes off me.” She pulled herself out of the water and sat on the side of the pool.

 

“Fine. You want me to be self conscious about myself as well?” You waded out of the pool and struggled to yank down your swim trunks. You couldn't help but blush alongside Rainbow Dash as your erection sprung free of your trunks as you kicked them off your legs.

 

“There. Now every time I stare, you get to see my erection from it.” Your crossed your arms over your chest to resist the urge to cover up. There was no way anybody could see either of you from behind your fence, yet you still felt venerable in the nude like this.

 

Rainbow Dash kept her eyes locked on you, her face scarlet as her gaze drifted from your eyes to your cock. “You don't have to go to such extremes just to make me feel better...”

 

“I'm going to. Any gal would KILL for the beautiful body you have. I bet Rarity would swap places for an instant for a butt like that.”

 

A smile slowly spread on Rainbow Dash's face. “Th-Thanks...You gonna cover up now?”

 

You shrugged your shoulders. “I dunno. I might need to make sure you don't revert to being a mopey marlin.”

 

Rainbow Dash continued to stare at your cock, her face growing a deeper red with every passing second. “Tha....That's not enough proof!” She bit her lip as she slowly pulled herself out of the pool and stood up. She rushed in close, pressing her wet breasts against your chest while her thighs squeezed your cock.

 

She looked you right in the eyes and smirked. “If you're REALLY okay with me being chunky, you'd back up your words with some action!”

 

Your hands immediately rushed to her ass and grabbed her thick, meaty buns. The flabby cheeks were too much for one hand with flab oozing from between your fingers. You pulled apart her cheeks, exposing the hidden bikini strap riding up her crack and let go. Her ass clapped together a few times, making Rainbow Dash blush even harder.

 

There was a pause as Rainbow Dash pinched her thighs together against your dick. You shuddered hard as her plump thighs did their best to tease you, pinning you between her womanly thighs. “Fuuuuuck!” You moaned as she flexed her thighs again, biting her lip as she felt your pulse through your cock.

 

“You really DO enjoy this, don't you?” Rainbow Dash slowly grinned as she pulled away. “What part to you like the best?” She asked as the struggling bikini was discarded to the ground. Her tits bounced free of her tiny top, relieved to be rid of such cramped confines. Rainbow Dash had to tug a little at her bikini bottoms to loosen them from her rear and work the wet cloth down her chubby thighs.

 

She gave a little spin, making sure to jiggle her plump assets for a big and give you a proper show. You couldn't help but stroke your cock a little, moaning as her fuller body really wobbled where it counted.

 

“The...The ass.” You begged. “I want that ass right now!”

 

“Well then...” Rainbow Dash growled as she strut towards you. “Come and claim it, if you REALLY say you want it.”

 

Once more, you dove at her body, lunging your hands behind Rainbow Dash and grabbing big, meaty handfuls of her ass. Your mouth peppered her face with kisses before slowly trailing down her neck and leading down to her cleavage. You stopped and pressed your face between her tits, savoring the softness and warmth smothering your face.

 

You pulled Rainbow Dash back and knocked over a bowl of chips before pushing her over the table. Rainbow Dash moaned as your hands gripped her cheeks and slowly spread them apart. Her pussy peeked from behind her thick ass, revealing how wet and eager she was.

 

Slowly, you pushed your cock between her cheeks and shuddered as her buns smothered your dick. You gave a little thrust and had to bite your lip as her ass wobbled out of control. Another thrust of your cock forced her rear to jiggle again and again, making both of you moan in delight.

 

Your hands gripped her cheeks tight, pushing them together and tightening their grip on your cock. A bit of readjusting and you gave another thrust. Rainbow Dash moaned as she felt your cock grind against her pussy just right, making her gush as her knees buckled.

 

A quick rhythm built up as you hot dogged the gloriously fat ass in front of you. There wasn't a moment where Dash's ass wasn't wobbling and shaking as the heavy plap of fat clapping against your chest filled the air. Rainbow Dash was a sputtering, drooling mess as a puddle was forming between her legs. You marveled as you watched Rainbow's ass engulf your dick so well that you couldn't see it peek through the top of her crack.

 

“Oh yesss....keep thrusting....I love it!” Rainbow Dash moaned as you gave her ass a mighty slap. You provided as much thrust as you could handle, grunting as you couldn't resist for long. Your hands gave her ass one final squeeze before you spread apart her ass and climaxed. Cum splattered all over Rainbow's gigantic ass, making her moan as each thick rope slowly trailed down her rear and dripped to the ground.

 

“Wow....I've never had that done to me before.” Rainbow Dash blushed as she turned around and kissed you hard. “I'm so fucking horny right now...I can't stand it.” She grabbed your hands and forced them on her plump tits, moaning as you squeezed her breasts hard.

 

“Again. I want more.” Dash shuddered as she pulled you to the water. She placed you on the stairs of the pool and smiled as she sat down on your crotch. The temptation of those soft cheeks teased your dick back to full mast, wiggling through her plump buns and pressing against her asshole.

 

“Nnnffff...” Rainbow Dash groaned as she slowly pushed herself down. Inch by inch, your cock slowly pushed itself into Rainbow's butt. Her body yielded to your advances as the horny girl sat down on your dick until her ass was rubbing against your balls.

 

“Fuuuucccckkkk.” You moaned as her body gripped you tighter than you thought possible. You tried to reach out to her hips but Rainbow Dash shoved them away.

 

She forced your hands against the walls of the pool and smiled. “Sit back and relax. I'll make sure this one feels great.” Rainbow Dash used the water to her advantage to ease herself up and down on your cock. Her hips wiggled with every little thrust, making it impossible to think straight.

 

Rainbow Dash blushed as her tits began to wobble about with her motions. “Augh...jeez. These damn udders are so...bleh.” You leaned forward and smothered yourself with her tits, kissing them all over as much as you could before Rainbow Dash pulled away.

 

“Perv.” She moaned as she sat back down. The resistance of the water kept her pumping slow and steady but the intimacy was worth it. You were able to kiss and worship her as she sat down and stare at her gigantic tits when she pulled herself up.

 

The urge to climax was building up again. You breath was growing short and your hands wouldn't stop twitching. “Dash....Getting close...” You warned her.

 

“So let loose, big boy. Show me you love this fat ass as much as you can.” Her taunts forced your hands to lunge for her hips, aiding her in her sexy sway while your hips crashed into her plump rear. You pumped as hard as you could until Rainbow Dash went limp in the water.

 

She hissed as her climax hit, tensing every muscle in her body. You gave one final push before burying yourself balls deep into her rear and shooting off more sticky ropes of cum. Rainbow Dash let herself fall forward, smothering you once more with her tits as she struggled to recover.

 

“Okay....point taken.” Rainbow Dash wheezed between heavy pants. “You like my ass...and every thing else.”

 

“Damn right I do.” You smiled before kissing her. She moaned into the kiss before easing herself up and off your cock. “So, when do we get you some bigger clothes?”

 

“Eh, it can wait...Kinda in the mood for some food.” Rainbow Dash walked out of the pool and dried off her hands. The chips were soggy and scattered all over but there were plenty of cookies, soda and other snacks left. “Could you start cooking those burgers? These cookies are good but nothing fills me up like meat, ya know?”

 

“Damn right I know.” You winked at Rainbow Dash as you wrapped a towel around your waist and headed inside. “Not like I mind. With the way she snacks, you'll need another two sizes up if that ass keeps fattening up like that.”
