Rocky Rides [RarityEQM’s Chapter]

It wasn't the tremendous jostle and jiggle of Pinkie Pie's broad beautiful bottom or the supple shape and roundness of Fluttershy's cushy behind, but it had a perfection all its own. Rainbow Dash carried with her, perhaps, the most muscular, powerful rump Spike had ever snuck a peek at. Really, it wasn't his fault she did all those stretches, and exercises, limbering up before races and jaunts around the track. And those skin-tight shorts she wore... Spike groaned. Often he let his mind old audience to the notion she was teasing him on purpose. Holding those positions just a little longer than absolutely necessary when she was stretching and letting the thin material of her shorts slide deliciously into the narrow cleft of her rump.

If Spike didn't know any better, of course. And he knew better. He knew she wasn't giving him an extra little waggle of her hips when she raced by, and he knew she wasn't flipping her tail out of the way to expose the sweaty glutes that shifted and rubbed against one and other when she shot past. She wasn't purposefully letting her trunks slide down far enough to give him a glimpse at the 'Y' of her crack, bare and prominent with her every movement, and she certainly wasn't wearing thongs for his enjoyment. She wore thongs everyday, not just for him, and today was no exception.

Spike, at least, wished she would have chosen to wear anything else underneath those tight shorts of hers. Anything at all, because as it happened, having his face pressed snuggly against her sweaty blue pussy was driving him absolutely wild. She hadn't stopped jogging since she set him inside of her shorts, and now that he was trapped inside of her thong, he wasn't going anywhere other than where she decided he would go. Every step forcefully found him flush against her dewy petals while the hefty scent of her overworked thighs stung at his nose.

Periodically, the ride would come to a halt and a blinding light would dazzle his senses, fresh air would rush into his nose, and a roar of the outside world rattled in his ears.

"How ya doin' down there, shrimp?" She giggled, the giant blue face peering down at him eating up every inch of vision he had. She was grinning her smug little grin, with an ever so slight hint of rose dancing along her cheeks. He smiled sheepishly and gazed up at her, lazily resting on the cot created by her stretched-out thong. He admittedly loved Rainbow's brashness. She was so open and carefree, that she'd be willing to pull her trunks out in the middle of the park, just to talk to the little dragon nestled inside of them.

"I-I'm ok..." Spike sputtered. The only answer his arousal-choked brain could manage. Rainbow grinned a little bit further.

"Oh yeah? Cause it looks like you're havin' a good time," She snickered. Yes. He had an erection. A wildly throbbing one, begging for another release. He pretended not to notice, but couldn't keep his own cheeks from pinkening. Oh, yeah, she was eating the attention up. He could tell. She was loving every second of making him worship her giant flower and every second that passed he could tell she was getting more and more worked up herself. Just the idea that something so small was trapped between her thighs, or wedged between her cheeks was making her gentle morning jog a smorgasbord of narcissistic indulgence. Well. As long as it made her happy.

"So, what's the verdict? You still good in there, or you want the back seat again?" She asked, the smugness in her voice not wavering an inch. Spike blushed profusely. An answer enough. She reached a choice set of blue fingers down and plucked him from the comfy confines of her crotch and held him up to eye level momentarily, looking him over, but mostly gawking at his pint-sized erection. More feed for her ego. Without a second thought, however, she reached behind her and grasped the rim of her jogging shorts, tugging them down, to moon the park behind her. With her other hand, she carefully guided Spike down, and slapped him against the crack of her bare blue rump, before she let go of the shorts to swallow him entirely. The firm cheeks gripped Spike tightly, a firm squeezing hug that groped him viciously and promised he'd not fall from the shifting globes anytime soon. No matter how fast Rainbow ran, those two cheeks were going to hold Spike prison for the rest of her trip. He gave a content little sigh, the fuzzy walls, already starting to twist and shift along his tiny frame.

And with that, she was off for another lap around the park.

Rainbow let her pace drift to a staggering halt, panting quietly and resting a hand against the nearest tree trunk she could. It wasn't that she was tired. Not at all, she could run for days. No, it wasn't her stamina that was giving her issues, but the little dragon wiggling in the crack of her rump. She had imagined teasing Spike like that would have been fun. After all, how many chances would she get to torment a pint-sized dragon? Especially one that wouldn't barbecue her afterwards. Especially one she had to admit was kind of cute. Oh, yes, teasing was certainly happening, but Rainbow hadn't planned to be the victim. She gave a grunt and tried to find her stride again, breaking away from the tree and hopping forward.

Instantly, she could feel him at it again, wiggling back and forth between her tight cheeks, burying himself as deeply as he could into her crack before climbing up to the 'Y' and down to the bottom. Each step was a teasing, tickling sensation that forced her to stumble and squirm. Guh! How was she supposed to run like this?! He was using her thong to find purchase in her butt, climbing it like a rope and sliding down it just the same, repelling off the rounded globes of her tight behind and digging his claws in when he climbed back up. It itched, it tickled, and the worst part? The absolute worst part of all of it, was she could feel herself getting more and more distracted the more he teased her. The front of her shorts were slowly but surely starting to grow a tad on the slippery side.

Rainbow gave a cold little growl and glanced around. The park was still empty. Good. She reached down and tugged open the front of her shorts, glaring quietly downwards at the sodden panties underneath.

"Hey!! The hell you think you're doin' in there?!" Rainbow growled. A few moments ticked by, and ever so slowly, Spike's head emerged from somewhere between her legs. A little dot of purple on the cotton of her underwear. He was small, yes, but she could see his ear-to-ear grin stretched across his lips.

"My butt is not a jungle gym. You knock that off!" she snarled. His grin grew even wider, and the tiny drake offered a cheeky salute in turn, before dipping his head back between her thighs and vanishing with a quick flash of his tail. Rainbow didn't like that grin. No. No, there was no way she'd let the little drake get one over on her. She reached down, trying to fish him out, but the dragon was surprisingly nimble. He clung to her slipper cheeks, and shied away from the fingers that tried to pinch him. When she'd nearly catch him, he'd retreat into the safety of her crack, lost in the snug shadowy depths where he'd wiggle and squirm against her. There was no way he was missing the signs of her arousal. Even past the saturating scent of sweat, she was positive he could smell her little blue pussy growing slick.

"What are you doing?"

Rainbow glanced up immediately. Flitter was standing in front of her, head cocked to one side, half a smile twisted across her lips. Rainbow stared, frozen in place, one hand in her shorts, the other holding them open and giving Flitter a perfect view of her thong and the wet mark staining the front of it. Slowly, Rainbow withdrew her fingers and forced a smile, wracking her brain for an excuse. Any excuse. Any at all!

"I...um..." were the only words that came out. Flitter, however, seemed to take it in stride, rolling her eyes and jogging past with a roll of her hips.

"Cute underwear," she chuckled as she sped off. Rainbow sighed letting her shoulders slump in relief before she immediately arched her back again. Spike was wiggling. Was he trying to press himself deeper into her crack? As much as she secretly enjoyed grinding the little dragon between her cheeks, it was starting to build a pressure that she was going to need to take care of sooner than later. It was a good time to start the trip home.

Rainbow Dash bit down gently, suckling at her lower lip as she fell into step behind Flitter. She'd never noticed before, but the other mare had curves to make a mountain road jealous. She was clad in a white sports bra that hugged her chest, partially see-through with sweat, and clinging jealously to her jostling breasts, but it was the plump, shapely backside that Rainbow had her eyes on. That Rainbow was following.

The tight green jogging shots Flitter was wearing looked as if they'd been painted on. They squeezed the twin globes of her rump, digging deep into her crack while allowing the lower part of her cheeks to peek out from the leg holes. They were entirely too small to be worn for jogging shorts and seemed like they'd be much more suited to a smokey bar with a lit pole in the center. She ran in a rhythmic jaunt, her hips delving into a hypnotic tick-tocking sway that waggled her firm-looking behind at Rainbow Dash tauntingly. The flicker of her tail only served to accentuate the globes, bringing attention to the way they would shift and grind against each other in a silent, rolling Siren's call.

Perhaps five minutes had passed, perhaps only one. Rainbow Dash found herself lost in her greedy gaze, those perfect shorts and pert, perky cheeks siphoning and sense of time passing she might have been able to discern. No, the only thing she could focus on were the delicious curves jiggling so temptingly in front of her. She did, however, notice when they stopped, and her head snapped up. Flitter was staring at her, the same coy quiet expression etched across her lips. Rainbow Dash blushed a solid shade of crimson and quickly searched for an explanation to her open ogling before Flitter turned around and started jogging again. Rainbow swallowed silently. If she didn't know any better, she'd swear Flitter was purposefully swaying her hips noq, a pronounced shift back and forth while she ran. Her tail seemed to be flickering higher and higher, no longer swishing back and forth, but held off to the side, as if to display the proud rolling cheeks peeking up from under the material.

Realizing she was staring again, Rainbow fell into pace, jogging until she could fall into step next to Flitter. She didn't acknowledge Rainbow at first, but Rainbow could definitely catch the warm smirk that tugged at Flitter's lips and a glance out of the corner of her eye.

"Wanna see mine?" she asked coyly. She hadn't stopped jogging, nor turned to address Rainbow Dash, but the question was clear as it was quiet. For a moment, Rainbow Dash shook her head in confusion.

"Err...your what?" she asked, keeping pace. She didn't turn to look at Flitter either. It was sort of strange, talking to another pony without looking at them, but Flitter had started it. The other pegasi's grin grew a little wider and for a few moments, she let silence fill the gap between them. Still staring straight ahead, the next words came just as quiet and just as clear as the question asked.

"Panties," she said quietly. Rainbow wasn't sure she'd heard her correctly. The pounding steps of her hooves against the pavement and the thrum of her heart beating in her ears made such a sly, coy comment difficult to hear, but she was positive she heard Flitter correctly. Her body certainly seemed to, her wings standing out from her back good and hard. Flitter's shy little smirk that followed was all Rainbow Dash needed for further confirmation, and slowly, Flitter began to veer her way out of the park, the last words she said ringing in Rainbow's ears.

"My place."

The ride was more or less a smooth one. Well, as smooth as a ride could be when one was riding in a thong. Still, Spike took the bumpy trip in stride. There really wasn't much he could do otherwise save cling tightly to the material and try not to let his own arousal suffocate him. Regardless of his attempts, however, the tiny dragon could feel himself gradually losing control. What could he do about it, though?! The rough grinding of his face against Rainbow's sweat-soaked pussy made it all but impossible for him to hold onto any slice of sanity he had. The tight blue walls hugged him warmly, sliding back and forth against his tiny frame with a delicious slickness that only seemed to enhance how easily Rainbow dominated his little body. If he turned himself juuuuust right, he could press his aching erection against the squishy, grinding walls, for a bit of relief, but he found himself enjoying the erotic balancing act. He was straddling the sensual precipice of an orgasm with every step and the pleasure that rumbled through him might have been better than the act itself.

But that's when everything stopped. Stopped? Rainbow had stopped. She was saying something to someone. The rumble of her voice seemed to reverberate through her form, shaking droplets of sweat and arousal around Spike's body. Then, Rainbow was running again. Faster, this time. A slightly different pace that the languid jog she was doing before. It was almost like she were trying to run away from something, or chase after something. Regardless, the end result was the same; the squishy hug Spike was getting before became an almost violent massage of his entire body. Without realizing it, he reached forward, instinctively to grasp hold of Rainbow's inner walls and squeeze tightly to steady himself. From somewhere above him, he could have sworn he heard a sharp little moan. Was that what that was? Was she getting wet? Spike drew in a deep breath, trying to pry through the numerous sensations that assailed his sensory input. She was obviously aroused, but now it smelled like it was a growing passion that was getting stronger. He certainly felt slicker, sliding back and forth between the hot little slit between her legs, but despite the pleasures of this newfound massage, there was somewhere else he wanted to be even more so...

With a herculean effort, Spike grasped hold of Rainbow's thong and began to hoist himself out of her slippery, sensitive pussy, pulling himself free, little by little until he could start making headway towards his goal: the tight blue cheeks around back.
