It was morning, and Rainbow Dash was in the mood to experiment. She had a brief moment of empathy for Twilight when she realized how excited she was. It could work, huge success, she’s happy. On the other hand, it could blow up in her face, and not in the good sticky way too. She wondered what Applejack was doing right now as she walked the Ponyville streets. She felt almost cripplingly guilty for leaving the woman asleep by the Appletree, naked and alone, but she had to. If she was right, that there was just something about… it, then she didn’t want to see how Applejack reacted. Either a torrent of punches and death, or a contagious sorrow that would inflict Rainbow with depression. She would check on her later, but for now, she had an experiment.

It was a Sunday, the only day in the week that Sugarcube Corner was closed to the public, and Rainbow had it on good authority that this fact was much to Pinkie Pie’s chagrin. The party pink girl could still be found in there, baking Monday’s goods and treats for sale, all free of charge. Her work ethic and loyalty to the job was something to be admired. She eventually reached the front doors, the sign predictably flipped to ‘closed’ and blinds obscuring the interior. Rainbow, her arm feeling strangely heavy, reached her arm out and knocked on the glass.

The response was near instant, a wide eyed “Oh, hey Dashie!”

“Yo, Pinkie. What’s up?”

“Oh, you know, the usual. Truffles, caramel candies, muffins, cakes, fond- ooh, fondue, I forgot about fondue, I should make some fondu-”

“Pinkie, Pinkie,” Rainbow snapped her fingers, tearing Pinkie from her food rambling stupor.

“Oops. Sorry, Dashie,” Pinkie squeed, grinning widely, her cheeks flustered, “well, I better get back to work. See ya lat-”

“Wait,” Rainbow blurted, hand raised, “I need to show you something…”

“Ooh, is it a present?” Pinkie exclaimed, excitement laden heavily in her voice.

“Something like that,” Rainbow smiled coyly at the girl’s choice of word. “I can only show you in private, it’s a secret, uh, present.”

“Okie Dokie!” Pinkie chirped, opening the door to allow Rainbow past, her full frame coming into view for the first time.

Rainbow Dash looked at Pinkie under the guise of courtesy, but in actuality, it was something more base. Pinkie’s scrupulous diet was enough to make a nutritionist faint, her avid and enthusiastic consumption of all things sweet was no secret, and if it was it was badly kept. Pinkie’s frame large and buxom, with wide child-bearing hips, and fat on her frame that leveled out nicely from top to bottom, most of it fortunately going to her breasts. Dash wish she was so fortunate. Then again, not much about the woman made sense. Dash still couldn’t fathom how she got her hair the way it was, defying gravity. Hairspray? Then again, she was a natural rainbow head. She found hair seldom made sense.

Pinkie closed the door behind her, the room partially devoid of light barring that which came through in slithers through cracks in the blinds. Rainbow preferred it. It would make sure a passer by didn’t see anything if this went woefully wrong. “I’m excited,” Pinkie said in a sing song voice, humming as she turned to face Rainbow, who stood fidgeting in the middle of the room. “So, what is it?”

Didn’t think it’d be this hard. Pinkie just stood there, looking at her. Of course the routine partier couldn’t feel Rainbow’s eyes looking her down from head to toe, nor did she read nervousness Dash was displaying in her movements. Rainbow looked to her large thighs, wide hips, and massive breasts, hoping arousal could fuel her to reveal herself. If it failed, she at least they’d have something to laugh about. Here goes nothing, she thought, thumbs wrapping around the hem of her pants, and yanked them down in one swift movement.

Rainbow stood straight up, pants around her ankles, her flaccid cock dangling to her knees. The only way she could do this was by clamping her eyes shut, but kept her ears open, hearing for some kind of reaction. A second passed, and then two. Maybe she’s in shock... nah, what am I thinking. She cracked open one eye, and when she didn’t see the blurred shape of Pinkie through her eyelashes, she opened them both. “Pinki- Pinkie!”

“Hmm,” Pinkie Pie was on her knees, her eyes looking over the flaccid cock and balls almost as if reviewing the presentation of a dish. “Something’s wrong with it, but I can’t put my finger on it…”

From her spot prior, to where she was now, Dash saw a trail of clothing. She not only managed to get completely nude from there to this spot, all the way to her legs, within seconds, but did it without making a sound. “Wha-”

“There we go!” Pinkie interrupted, her fingers coiling around the hardening shaft, licking her lips. “I love the present by the way.”

“Pinkie,” Dash groaned, finding it hard to stay steady as Pinkie pumped her cock, the baker’s hands surprisingly fluid in the motions. Dash found Pinkie more… reserved than Applejack, a statement she surprised to even think. In honesty, Dash couldn’t tell if Pinkie was under some kind of effect, and it was just Pinkie being Pinkie, but if she was in some kind of… trance? Then it looked like different girls reacted differently. Well, whatever it was, Dash hoped any time she did this in the future it would be just as good as this.

Pinkie had another hand join the first, one hand squeezed up toward the tip, the other stroked down over the medial ring. At one interval, Rainbow moaned, a large dollop of pre leaking from her erection. “Ooh, pre, tasty!” Pinkie exclaimed, and before Dash knew what had happened, she was curled over in bliss. Her entire shaft had disappeared down the baker’s throat, the warm moist consumed Rainbow’s cock all the way to the hilt, and in the haze of her lust she had one coherent thought. More accurately, a single word: fuck.. Pinkie pulled back in a single movement, her tongue circling the entire length before it left her mouth with a *pop*, and she smacked her lips; licking them and going into deep ponderous thought. “It’s missing somethi- Oh, I know!”

“Pinkie, wha- woah!” The pink coated girl dashed between Rainbow’s legs, suddenly leaving her partially off balance has her legs were spread wide. “Pinkie! What are yo-”

“Perfect!” Pinkie’s voice declared right next to Rainbow’s ear, and just as she was about to fall over in surprise, the larger woman wrapped an arm around the athlete's midriff. Dash brought close to Pinkie, who rested her chin on Rainbow’s shoulder, her large F-cup breasts pushing into her back. Dash was to confused to speak, and looked Pinkie’s other hand. Is that…? “Whipped cream!”

Dash didn’t have time to expression confusion, Pinkie already got to work. Along the length of Dash’s rod Pinkie sprayed the cream, the spray job messy since Rainbow’s erection kept twitching, leaving some of the cream on the floor. Dash had a feeling Pinkie didn’t particularly care. Immediately after, Pinkie, using Rainbow as an anchor, slid onto her back; swinging through Rainbow’s legs. “Whuh?” Dash muttered, Pinkie’s head between her angles, a maneuver that despite her agility managed to confuse her.

“Come on, Dashie, feed me my treat!”

“W-what?”

Pinkie rolled her eyes, but the smile remained on her face, aspiring to an almost sultry quality. “Fuck my mouth, Dashie.”

“Oh… Oh!”

Dash was quick to fall to her knees, shuffling back until she could align the cock with Pinkie’s mouth, who looked at it upside down; licking her lips. When Pinkie opened her mouth, the strings of spittle connecting her lips, Dash bit her lip at such an erotic sight. She inched her meat forward, Pinkie’s stillness was slightly unsettling but her desire to fuck such a sightly hole overpowered her negative feelings. When the flare passed through Pinkie’s lips, Rainbow tensed up, Pinkie’s tongue already working on the inch of horsecock in her maw. A thousand lashes of the tongue seemed delivered within an instant, pressing against her urethra, lapping up the pre before it even had a chance to leave her shaft.

Despite Pinkie’s already above-average skill in the art of fellatio, Dash wanted more. She made a little thrust, shoving a quarter of her cock down Pinkie’s trap, Pinkie’s tongue making her weak in the knees; prompting her to fall over and land head first on Pinkie’s cushiony bosom. She’s couldn’t have fallen anywhere better really. Pinkie Pie slurped around Rainbow’s shaft, her lips forming a seal, massaging her length with just her tongue and lips. She had already hit the back of Pinkie’s throat, and yet there was no lull in her efforts. Her skill was beyond Rainbow’s comprehension. Rainbow had a secondary goal in mind, and completion of that goal required travelling up Pinkie’s body, which in turn meant...

“Aw, fuck,” Rainbow exclaimed, shoving more of her length down Pinkie’s hole, so much was within her mouth by this point that one could see it throbbing in her bulging throat. There were only so many ways one could describe the pleasure Dash was going through. Pinkie’s tongue was almost like magic, the fact Dash could feel it licking at the tip of her member as well as that which passed her lips didn’t seem possible.

Dash made another effort, thrusting her hips this time, she shoved her cock past the medial ring. Which she would have nearly considered a mistake. Pinkie seemed self-detrimental at this point, her tongue circling Dash’s sensitive ring, licking in zig-zags the entire circumference of Dash’s meaty pillar. Rainbow found she couldn’t move, curling over in bliss, but hadn’t yet reached orgasm. A surprise even to herself. She looked to see her destination, and to her relief she had stopped right over it.

“Ooh~” Pinkie was for the first time given pause to her fellatio, Dash’s middle finger passing through her folds
whilst her tongue drew tiny circles around her clit. Sixty-nine. Pinkie tasted, which somehow left Rainbow feeling surprised, like cherries. Rainbow knew she was way out of her league compared to Pinkie, but she tried to at the very least provide the pink coated mare some satisfaction.

Whilst Pinkie was stunted, Dash remembered what she said before about ‘fucking her mouth’. She glanced down, and noticed the last quarter of her cock remained outside Pinkie’s gullet. She took it no problem before, and she did ask… Dash, tentatively, embedding her full marecock in Pinkie’s throat. Dash continued to finger Pinkie, biting her lip when the baker resumed her oral work on Dash’s appendage, but now she had a selfish idea drilled into her head. She withdrew just shy of the medial ring, and thrust it back in, her balls smacking against Pinkie’s forehead; Rainbow released a groan from her throat, but noticed that Pinkie’s honeypot clenched around her finger. Did she like that? Rainbow tried again, and sure enough, Pinkie clenched… Rainbow Dash grinned. Just like Applejack. She moved her hands from Pinkie’s twat to her hips, and spread her legs. She was going fuck Pinkie’s throat.

Dash pulled her cock halfway out Pinkie’s mouth, saliva streaking down the length, Pinkie’s lips remained tight around Rainbow’s girth. Rainbow felt Pinkie wrap her arms around her, seemingly in a preparatory manner before Rainbow slammed her cock back down Pinkie’s throat, both of them releasing moans of ecstasy as Rainbow’s horsecock hilting in Pinkie’s throat. Rainbow felt Pinkie’s hands on her dick through her throat, the mere thought of it made Rainbow moan. It wasn’t long before Rainbow repeated the motions, and began to comply with Pinkie’s order, pulling out her sex and thrusting it back in; both to their satisfaction.

After a while, Rainbow picked up her thrusts. She raised herself up straight to achieve this, fucking Pinkie’s mouth with short and fast thrusts, pushing her hips until her sack was obscuring half of Pinkie’s face; the orbs began to churn with the telltale sign of approaching orgasm. The closer she got, the less she recognized her friend. She began to see Pinkie’s throat as her own personal cocksheath. It was her hole, her hole to fuck. Fuckhole. Pinkie’s throat was her fuckhole. She got so lost in this sentiment, that when she wrapped her hands around Pinkie’s chest, she immediately went to degrading Pinkie to just that.

“MM~!” Pinkie moaned around Rainbow’s marehood, her nose getting the full assault of her must as her mouth was fucked. Rainbow was merciless, her balls slamming into Pinkie’s face as she forcefully used her moist maw. Fuck, fuck, fuck, went through Rainbow’s head as she assaulted Pinkie’s throat, and as she neared bliss, she went into overdrive; leaving only an inch out of Pinkie before slamming back in with unnecessary force.

“I’m cumming, I’m cumming, I’m cumm-” Rainbow gushed as her horse member flared in the back of Pinkie’s throat, unleashing rope after rope of her sticky batter down her throat; her tongue falling out her mouth as she threw her head back. Bliss. She saw Pinkie’s legs quiver, a small splash from between her legs as she came, practically screaming around Rainbow’s shaft, eyes rolling into the back of her head.

Rainbow sighed, and rode the afterglow for as long as possible, before she looked down at her partner. “Pinkie, that was amazing!” She smiled, but soon the smile fell, and she had concern in her features. “Pinkie… Pinkie, you okay?”

Dash waited a moment, hanging on the silence. “Mmph,” came a weak, blissful, groan from Pinkie’s cock stuffed mouth.

“Ah, good… good.”

Who else can I see on a Sunday morning? She pondered, still balls deep in Pinkie, thinking of her next lay. Who else worked a local business that was closed on a Sunday...
