Not Much There

Slutty Wonderbolt Costume

Rainbow Dash stared at the package, one eyebrow raised. She still could not believe what she was reading, and she really could not believe she had actually bought the Discord damned thing. What in Equestria had possessed her to do such a thing? She had an actual Wonderbolts cadet uniform, and could easily get her hands on an active members uniform even if it did not actually fit her properly. There were other sexy costumes she could have picked from, some of which would have been much more interesting to surprise Soarin with.

Although judging from the picture, the thing looked nothing like either of the real uniforms.

Pulling the package open, she took the contents out started separating it to get a look at the thing. The entire thing looked to be made from some sort of shiny metallic material that reminded Dash of those metallic balloons. There was a set of leggings and... sleeves? Handless shoulder length gloves? Whatever. Dash did not really care what they would be called. If she did, she could always ask Rarity about it some other time.

Then came the main outfit.

Rainbow Dash felt really ripped off. There was barely anything to it, especially since there was a massive hole in the middle of it.

Well, I bought the thing, Rainbow Dash thought, may as well try it on.

After undressing and dropping her clothes on the floor, she put on the costume. It was a bit confusing since it was basically a giant floppy ring of fabric, but somebody had thought to print a label on the inside, letting her know which part was the top and back. It still took a while to figure out how to get the damned thing on.

Once she had managed to get the costume on, the design of it made a little more sense to Rainbow Dash. Not much, but a little. The top went from shoulder to shoulder, with a slightly raised collar that went around her neck. The back of it was open, allowing her wings and tail to be free. Underneath the tail, the the sides met and basically became a thong strap, just covering the crack of her toned ass and waiting for her to bend over and shift too much to give Dash a wedgie. The front of the outfit was also open, exposing her muscular abs. The bottom was cut so low, it just barely covered her pubic mound. Although not very well since she could see a faint outline for her vaginal lips through the material. Jagged lightning bolts edged the front, leading up from her crotch to the collar. The fabric covered her nipples while leaving the inside third or so of her breast exposed. Looking at it, Dash figured that a larger breast would have a hint of the areolas. With her own more modest bust, they were covered, but she could see her nipples poking against the material.

It felt weird, but Rainbow Dash thought she also looked pretty good. The thing totally showed off nearly every part of her body. Smirking at herself in the mirror, she could not help but pose and flex. Spreading her legs wider, she placed her fists on her hips and clenched her abs. She then lifted up her arms and flexed them, tensing and shifting her biceps.

"Ooh, yeah," she said as she turned around. "I am one hot mare." She spread her wings wide and clenched her butt.

Actually, now that she thought about it, Rainbow Dash felt a little warm. Whatever the outfit was made out of, it did not breathe well. Giving a gentle tug of the outfit, Dash found herself grateful that there was so little to it now.

Except she was not wearing the entire thing yet, just the main part. Grabbing the leggings, she slipped them on, flexing her calves and thighs as she did. Then came the sleeves, which went up to her shoulders and had a finger hole at the end. Dash found both a little unpleasant. They were tight around the thighs and bicep, and uncomfortable to her elbows and knees. It actually felt like she could burst them if she flexed too hard. Although really they would have to be more resilient than that.

Standing back up, she flexed and posed a few more times. It was not as much fun with the limb covers. They took away from her posing and flexing, hiding some of her muscle tone beneath the material.

As she continued to move and shift in the outfit, Rainbow Dash felt a very different kind of heat building up. Every move she made caused the material to rub against her nipples and vulva. It was kind of pleasant, although the building wetness between her legs was getting a bit uncomfortable in multiple ways.

"Dash?"

The masculine voice made Rainbow Dash jump slightly. Turning around, she gave a quick glance at the clock.

"You're early," she called out, feeling her face heating up. It had been her plan to be wearing the costume when Soarin came over, but now that he was there, she was having serious doubts. Why did she want to do this? What made her think this was sexy? What if he doesn't like it? This was stupid. This was so not her.

"Things went a better than expected," Soarin called out, his voice closer to Dash's bedroom than it had been before. "Although first thing Monday morning, Spitfire wants...us...too..."

Soarin stood at the door in his dress uniform, green eyes wide and mouth hanging open as he stared at Rainbow Dash. His wings slowly spread out behind him, thumping against the door frame. The reaction got a smile and chuckle from Dash.

"So I take it you like it?" she asked, turning around slowly, wings spread wide. Dash was tempted to strike some poses, but she was not certain if she knew any that would be considered sexy. Maybe she should get some tips from Rarity before next time. Assuming there was a next time.

"You... you... you look... beautiful," Soarin finally managed to say.

The compliment got a new blush from Rainbow Dash. She had been called tough, athletic, even sexy and a couple times -- much to her chagrin -- cute, but she had never been called beautiful before. Dash had never really been a figure of classical beauty. She was too thin. All lean muscles and nowhere near enough breasts or hips. It was something that she was fine with, but had never thought she would be called beautiful by a stallion.

Although it was kind of weird that he would choose to say it while she was dressed in a sexy costume.

Slowly, Soarin's wings pulled back in as he walked forward, moving closer to Rainbow Dash. One hand reached out, placing it onto her hip and stroking down along the outside of her thigh.

"It really shows off your body," he said, eyes focused on her chest.

Rainbow Dash took a hold of his tie, running her fingers up along the length of it. Her ears pulled back as her eyes narrowed, trying to give a sexy look.

"How about we get you out of this uniform, and then you can give me a... full 'inspection.'" She gave him a wink, then pulled Soarin forward, pressing her lips against his.

The action caught Soarin off guard, his body tensing as he was pulled against Rainbow Dash. As the kiss continued, he began to relax, pressing himself into it more. Wrapping his arms around her, he placed his hands onto her rump, giving the firm cheeks a squeeze. The front of his dress pants bulged with his growing arousal, the wool rubbing against the fur of Dash's stomach. His hips started to rock, rubbing the bulge against the toned muscle.

The kiss broke as Rainbow Dash moaned out, shifting to press against Soarin's hands and pants. Her long rainbow tail gave a flick as it raised up as high as it could.

"Seems like someone is pretty excited already," she said as she rocked against him.

"My sexy girlfriend is showing off her hot body in a slutty costume," Soarin replied. "How could I not get excited?"

"Well then," Dash growled out (in what had been an attempt at a sexy purr) as she took a hold of his tie, "how about we get you out of this uniform, and you show me just how much you like this."

As Rainbow Dash continued to undo his tie, Soarin slipped off his jacket. As he went to undo his shirt, Dash went for his pants. Her hands quickly worked to undo the belt and pull the fly open. Grinning to herself, she slipped her thumbs into the waistband of his underwear and pulled down.

Soarin's dick popped up, bobbing as it came free of its cotton confinements. Rainbow Dash pressed her palm against the underside before gripping it, giving it a slow stroke up to the top. As she continued to run her hand along the length, she leaned up to kiss him again.

A small moan escaped the stallion. His hips pushed up and forward, rocking to grind against Dash's teasing. The shaft twitched, a small bead of pre forming on the tip. After dropping his shirt onto the floor, he reached down and grabbed Dash's ass again. One finger slipped under the costume, tracing along the cleft of Dash's cheeks and down between her legs. As soon as he felt the warm wetness of her vaginal lips, he pushed up, sinking the tip of it into her.

The feel of the digit penetrating her made Rainbow Dash moan out in pleasure more. Her body tensed, squeezing on the length. Her own hand stroked down further, slipping into Soarin's underwear and gripping his sac. She gave the nuts a gentle squeeze before stroking up along the length once more.

A large bead of pre-cum formed on the tip as Dash made her way up the hard cock. Pressing her thumb onto the top, she rubbed the sticky fluid onto the sensitive head.

The kiss broke as Soarin let out a moan of his own, his shaft twitching with excitement.

Rainbow Dash let go of the shaft and pulled away, the finger slipping out of her pussy as they separated. Her grin grew wider as she moved backwards onto the bed. She then reached down between her own legs.

"Considering how this thing is made, I don't think we need to bother taking it off." Spread her legs wider as she took a hold of the costume's crotch and pulled it aside, revealing her swollen and wet vaginal lips.

Quick as he could, Soarin slipped out of his slacks and briefs, letting them drop to the floor with the rest of the clothes. The stallion leaped onto the bed, pinning Rainbow Down with his body. Moving closer, he nipped at her ear, letting his tongue flick along the captured appendage. His hips pressed down, grinding his hard shaft against Dash's toned body as it stroked its way down her stomach and toward her exposed target. The head leaked the entire time, leaving a trail of pre along the mare's fur and costume.

Rainbow leaned up, pressing her face against Soarin and nibbled on his collarbone. One hand stayed where it was, holding the crotch of the costume aside. The other took a hold of the stallion's rock hard cock as it reached her nether region. Giving it another long, gentle stroke, she pressed it against her sensitive and swollen clit before lining it up with her opening.

There were cries of pleasure from both of them as the head of Soarin's shaft spread Dash's lips, working its way into her warm wet depths. No longer needing to hold the costume aside or help Soarin find the mark, Rainbow Dash let go of both and wrapped her arms around the stallion. Her fingers dug into his back, just beneath the base of his wings. Lifting her legs, she wrapped them around his waist, heels digging into the backs of his thighs. As he pushed deeper, her hips shifted, grinding against him.

Soarin's jaw clenched as he pushed forward, working to sink his way fully into the warm, wet depths. He had never felt Rainbow Dash so aroused before. Not even fully inside her yet, and he could already feel her squeezing and stroking him. If this was any indication, she was not going to last very long. Although to be fair, if she kept it up, he would not last very long either.

Once Soarin was fully inside Dash, the two of them held still, letting the edge wear off a little.

Rainbow Dash moved away from Soarin's shoulder and pressed her mouth to his. Her chest pressed upward as she shifted, rubbing her nipples against the material of the costume and sending tingles of pleasure through her. She rocked her hips, trying to grind the swollen and sensitive button of her clitoris against him.

Her legs relaxed some as he felt her shift, beginning to pull backwards. A small whimper escaped from her as she felt the shaft slowly moving along her walls, slipping out of her depths. Her muscles gripped at the shaft, trying to keep it from escaping. Dash knew he was pulling back to thrust in again, but a part of her worried that he would slip out.

Dash's attention was drawn to her mouth as she felt Soarin's tongue slipping into it. A full moan escaped her as she tightened her grip, fingertips digging hard into the stallion's toned back. Her tongue shifted, pressing against his.

The medial ring tugged at Dash's nether lips as it pulled out, only to push back inside. It was a short, hard thrust, burying the entire length back in with a slap of their hips against each other. The movement got a gasp from the mare, her walls clenching down hard as her entire body tensed in surprise and pleasure.

Soarin soon fell into a rhythm, pulling out slowly until the ring slipped free, then giving a short hard thrust all the way in to the base. With each forward movement, Soarin would grind hard before pulling back again.

The kiss broke as Rainbow Dash threw her head back, groaning out in pleasure. Her eyes closed as her tongue fell out of her mouth, pants escaping from her. With each backward pull from her, Rainbow Dash lifted her hips, changing the angle and teasing herself even further. With each movement of the ring in and out of her, Dash was sent to greater and greater heights of pleasure.

"Faster," she cried out.

Doing as he was told, Soarin picked up the pace. His own head thrown back, he gave short, hard thrusts against Rainbow Dash. Each thrust was fast and hard, hips slapping together as he pushed as deep into her as he could before pulling back again.

During one particularly hard thrust, Rainbow Dash reached her limit. She pulled her legs tight against Soarin, locking him in place as her body tensed in pleasure. A cry escaped her as she hit her orgasm. Clenching down, she squeezed and stroked the length, trying to milk it.

The increase in pressure and pleasure sent Soarin over the edge. Pushing forward one more time, he buried his shaft as deep as he could get. His hips shifted, rocking and grinding as he tried to push deeper still. A grunt escaped the stallion as his shaft swelled and twitched, pumping the thick ropes of warm cum into the wanting depths.

Once the orgasms had ended, the two of them pulled apart, Rainbow Dash going limp as Soarin fell onto the bed beside her. The couple laid there, panting in pleasure and staring up at the ceiling for a moment.

Rainbow Dash was the one to move first.

"Well that was intense," she said as she got up. "But I gotta get out of this thing. It does not deal with heat well." She took a hold of one of the sleeves and dropped it onto the floor. "Think I'll take a shower as well." Turning to look over her shoulder, she gave a smirk.

"Wanna join me?"

"Absolutely," Soarin said with a smile. "You go ahead and get started though. I need to hang up my uniform."

"Alright," Rainbow Dash replied as she took of the other sleeve, "but don't take too long, or I'll start without you." She then started for the bathroom, making sure to put some extra wiggle in her hips so her lean butt shook back and forth more than usual.

Soarin watched a moment before she vanished from sight. once she was gone, he got up and grabbed his dress uniform, quickly putting it on the hanger and setting it on a door handle. He did not want to have Spitfire tearing into him if it somehow ended up wrinkled. He then quickly made his way toward the bathroom.

Just outside the door, the sound of water reached his ears. The image of Rainbow Dash in the shower formed in his mind. The image of the water running down her body, making her fur and hair stick close to her skin. Every toned muscle would be better defined, the streams tracing along each and every line and filling every groove before falling to the floor. The small, firm breasts. The lean, curved ass. The toned arms and legs. Powerful thighs and calves.

Despite having just finished having sex, Soarin's shaft started to twitch at the mental image of a soaking wet Rainbow Dash. He did not have to simply settle for imagining it either. Opening the door, he stepped inside and made his way to join her in the shower.
