Safely back in their hotel room, Vinyl began to sift through the large sack of toys she had brought along, surfacing moments later with two of Trixie’s magical feeldoes.

Rainbow frowned. “You guys have two?”

Vinyl grinned. “Nah, I just swiped yours while you were getting ready this morning.”

“Probably best we have it with us, anyway,” Applejack supposed.

“But you know what this means, don’t you, AJ?” Rainbow insinuated.

Applejack blinked.

Rainbow rolled her eyes, taking both feeldoes from Vinyl and hoofing one to Applejack. “We can finally see who’s bigger, obviously.”

Applejack cocked a brow. “Ya’ve already seen mine. Really think ya can beat that?”

Rainbow rolled over onto her stomach and pressed the bulb into her folds, grinning proudly at the impressive growth of the toy as it melded into her crotch. “Put ‘em up, Jackie.”

Applejack felt a spark of competitiveness ignite within her as she lay across from Rainbow. “Ah could take that.”

“All the way to the hilt?” Rainbow challenged, propping her length up with a hoof.

Applejack smirked. “Wanna bet on it?”

“It’s okay if you’re scared.”

“What makes ya think Ah am?”

“You haven’t put yours in yet.”

Applejack blinked, remembering the purpose of their current position and quickly resolving the issue. As Applejack’s shaft clapped against Rainbow’s, Rainbow wasted no time in shooting up into the air.

“Aw yeah, I’m bigger!” Rainbow boasted.

Applejack frowned. “Hold on a second there, Dash. Yers might be longer, but mine’s a good bit thicker.”

Rainbow scoffed. “Please, AJ, everypony knows length trumps width.”

“I don’t know, Dash,” Vinyl chimed in. “Length is great up to a point, but if it starts getting to the point where you can’t fit it all, width comes out on top.”

Rainbow glared at Vinyl. “You’re not part of this, Scratch! This is between me and AJ.”

Vinyl held up her hooves defensively. “Hey, I’m just saying you gotta do the math.”

Rainbow frowned. “The hell’s math got to do with this?”

“I do believe Vinyl means we should conduct a more accurate test to settle your dispute,” Octavia answered. “And I happen to know that Vinyl brought a tape measure.”

Applejack blinked. “And why exactly did she do that now?”

“You never know when you’re gonna need to measure something,” Vinyl responded. “The same reason ponies wear watches, right?”

“Yes, and I suppose you’re going to affix a clock to it at some point to give yourself a device that can measure both space and time,” Octavia humored.

Vinyl’s eyes widened. “That’s a great idea! Has that been invented yet?”

Octavia sighed, shaking her head helplessly.

“So, yeah, that’s great and all, but there’s a contest you guys are holding up here,” Rainbow piped up.

Octavia rolled her eyes, ducking her head into Vinyl’s bag in search of the item in question. Upon retrieval of the measurement device, Octavia barely had time to right herself before she found a dick inches from her face.

“Measure me first!” Rainbow demanded.

Octavia frowned, brushing the offending penis out of her eyes. “I’ll be getting to that. But first I need something to keep a tally.”

Vinyl produced a pen and a notepad from the nightstand.

Contingencies accounted for, Octavia began her measurements, starting first, as requested, with Rainbow.

“Fifteen noses long by two and three fifths thick,” Octavia informed, jotting the numbers down.

Rainbow smirked. “Ha!”

Applejack rolled her eyes and let Octavia complete her research without comment.

“Thirteen noses long by three thick.”

“See? Ah’ve got almost half a nose on ya,” Applejack asserted.

“And I’ve got a two noses on you,” Rainbow shot back.

Octavia coughed. “Actually, despite the different distribution, the mass of each is identical.”

Applejack cocked her head. “Come again?”

“You are essentially the same size,” Octavia clarified.

Rainbow frowned. “You mean we tied?”

Octavia shrugged.

“But then what happened to those extra noses I had?” Rainbow prompted.

“Your extra length is equivalent to Applejack’s extra width,” Octavia went on. “We’re dealing with percentages here, not raw numbers.”

“Does it really matter anyway? You’re both monsters,” Vinyl added.

Rainbow shared a glance with Applejack before gaining a proud grin. “Jealous, Scratch?”

Vinyl cocked a brow. “Why would I be? I’m the one getting the benefit.”

“If ya think ya can keep us around, maybe,” Applejack smirked. “Ah’m not one ta share new toys with guests first.”

Rainbow nodded. “AJ’s got first dibs on this one, Scratch.”

Vinyl huffed. “You guys are jerks.”

“Hoping to have them all to yourselves, were you?” Octavia teased.

“I was gonna give you whatever else you wanted,” Vinyl defended. “Like, hopefully my horn. In your plot.”

“I can think of something I want in my plot,” Rainbow grinned. “You guys did bring other toys, right?”

Vinyl responded by levitating the sack she had carried from Ponyville onto the bed.

Rainbow’s eye was immediately drawn to one toy in particular. “Hey, AJ, how many apples do you think you could fit in your ass?”

Applejack blinked at the strange question, and was about to assert that she wasn’t one to waste a good apple, until Rainbow pulled a string of apple-shaped anal beads out of the sack.

“Didn’t think I meant real apples, did you?” Rainbow chuckled. “Though that would be pretty hot.”

Applejack smirked. “How come we haven’t used these yet, anyway?”

Rainbow shrugged. “I guess there was no real point after the whole hoofing incident. I definitely want another shot at that, though. Just, you know, after stretching out a bit.”

“Wait, hoofing incident?” Vinyl cut in.

Applejack blushed and looked away, prompting Rainbow to explain. “Yeah, I teased AJ a bit too much, she got a bit too rough, next thing I know her whole hoof’s in my vag. Just stopped feeling sore earlier today.”

Vinyl raised her brows, impressed. “Damn, Dash, that’s pretty hardcore. Might wreck yourself if you try that again.”

Rainbow waved a hoof. “Nah, I can take it. Just need practice is all.”

“Famous last words,” Vinyl teased.

Rainbow rolled her eyes, turning back to Applejack. “I was serious, by the way. How many of these you think you could take?”

“You takin’ bets?” Applejack challenged.

Rainbow thought for a moment before sticking her head back in the sack. “Better, how about we go apple for apple?”

Octavia chuckled. “Everything’s always a competition with you two.”

Rainbow retracted her head with a second set of apple beads hanging from her mouth. “Well, yeah, it’s more fun that way.”

“And I suppose we’re only here to watch,” Octavia gathered.

Rainbow cocked a brow. “Looking for a little audience participation?”

Octavia smiled, “No, you two have your fun. Just make sure you’ve got something left for afterwards.”

Rainbow grinned. “Alright, so let’s lay down the rules. Each apple needs to be taken full size. Preliminary stretching is allowed, but is limited to medium sized dildos.”

“Think yer forgetting something, Sugarcube,” Applejack hinted.

Rainbow blinked. “Huh? Oh, yeah, we should probably clean and lube up first.”

Vinyl tossed over a bottle of lube, forcing Rainbow to catch it before she could stand up. “That’s all you’ll need.”

Rainbow frowned. “Uh, what?”

“Read the label before you buy something, Dash,” Vinyl chirped.

“Please, Vinyl, you would have done the same thing if Trixie hadn’t explained it in such… uncomfortable detail,” Octavia chided.

Still confused, Rainbow looked for the label and read it aloud. “Trixie’s Magical Lubricant.”

“Below that,” Vinyl goaded.

“For anal use only?” Rainbow read off.

Vinyl sighed, swiping the bottle away and pointing out the tagline. “Cleans and lubricates.”

Rainbow blinked. “Wait, are you serious?”

Vinyl returned the bottle without saying a word more.

Rainbow opened the cap and squirted a glob of the clear liquid onto her hoof, inspecting it for a moment before reaching down to dab it on her plot. The effects were nearly instantaneous, and the strange sensation elicited a gasp from the startled pegasus, who was left with a sense of emptiness.

Rainbow grabbed a dildo from the sack and pressed it into her star, suppressing a moan as her ring stretched to accommodate the intruder. Cautiously, she sunk the toy deeper, until there was surely no denying it. But still Rainbow was in disbelief. “No way.”

“Yep,” Vinyl confirmed.

That single syllable was all Rainbow needed. “That’s so awesome!”

Applejack hummed, picking up the bottle in her hooves.

“Certainly a convenient solution to an undesirable problem,” Octavia added curtly.

Rainbow smirked. “So, about that-“

“Shut up,” Octavia interrupted. “Just shut up. It never needs to be spoken of again, so please just… leave it at that.”

Applejack shrugged, applying the lubricant to her own rim. “Works for me.”

“Does kinda make me wonder about that ‘for anal use only’ thing, though,” Rainbow commented.

“You got another one of those in there, or are we gonna have to share?” Applejack wondered.

Rainbow snickered, slipping the dildo out of her ass. “What, worried about catching my butt cooties?”

Applejack chortled. “The hay does that even mean?”

Rainbow shrugged, hoofing the supposedly infected toy over to her marefriend.

Applejack pressed the head of the dildo against her star, biting back a moan as it stretched her ring and sunk inside. “You know, Ah kinda figured you’d be more eager ta get back into vaginal stuff now that ye’re healed up.”

Rainbow snorted. “Sorry, but I’m not in a rush to wreck myself again. There’s no way I can fit all that in my vag. It’s not even summer yet.”

“Ah’m not complaining,” Applejack amended with a sigh as she hilted her toy. “Ah’m gettin’ a real kick outta this; more ‘n usual.”

“I would imagine that would be thanks to your new genital arrangement,” Octavia observed. “Vinyl has the most experience here with these things, and she’s told me the transformation is quite thorough.”

Vinyl wrapped her magic around the dildo in Applejack’s ass and began to wiggle it around. Applejack gasped as the medial ring brushed against a hypersensitive spot on her rectum and grinded against it incessantly.

Biting her lip, Applejack fought against the sudden surge of intense pleasure, but she could feel herself mere moments away from an explosive climax when Vinyl’s magic faded as unexpectedly as it started. Applejack grabbed the toy with her tail and battered it against her rim desperately, but she lacked the knowledge and dexterity to find that spot again before she fell from her high and was left panting and painfully unfulfilled.

Applejack groaned. “Why did ya stop?”

Vinyl grinned sheepishly. “Sorry, I’m not really that good with magic. If Strings was here she would have done it better.”

“What did you do to her?” Rainbow wondered, very interested in experiencing it herself.

“I just found her prostate,” Vinyl explained. “It’s kinda like a g-spot but like a thousand times more sensitive.”

Applejack floundered around on her back until Rainbow helped her to her hooves. “If that’s what it’s like fer a colt Ah can’t imagine why Mac went fer Rarity so quick.”

“She’s got hooves, doesn’t she?” Vinyl supposed.

“Even if she knew about this stuff, Ah can’t imagine she’d be too keen on anal,” Applejack mused. “Though Ah could see her keepin’ a bottle around anyhow to avoid ever havin’ to use the bathroom.”

“They say it’s usually the innocent ones that have the most perverse desires,” Octavia pointed out.

“It ain’t that she’s innocent, it’s that she hates gettin’ dirty,” Applejack amended.

“It’s not dirty if you do it right,” Vinyl added.

Applejack sighed. “Ah know that, but Ah don’t know if she knows that.”

“We’re here to have a good time, not gang up on my marefriend,” Rainbow supported.

Vinyl grinned. “You know, that doesn’t sound like a bad idea. Rainbow can take her ass, I can take her dick, and Tavi can take her mouth and mine.”

“Sounds good to me!” Rainbow agreed. “AJ?”

“Only one problem, sugarcube,” Applejack began, prompting groans of disappointment. “You’ve got first dibs on this thing.”

Rainbow smirked. “Well, it does look tasty.”

Applejack snorted. “You ain’t got tastebuds where Ah’m stickin’ this.”

Rainbow shrunk. “Wait, I-“

“Hold her down,” Applejack ordered.

Vinyl pounced the moment Applejack closed her mouth. Rainbow struggled to free herself, but Octavia was quick to reinforce. With her superior strength holding the pegasus down, Vinyl was free to position Rainbow’s back end appropriately.

Applejack clucked her tongue at the sight of Rainbow’s presented plot. No matter how much she squirmed, the pillar of flesh jutting out below her made it impossible to hide her arousal.

“Dammit, you guys, this isn’t funny! Let me go!” Rainbow whined.

Applejack grinned predatorily. “This ain’t a joke, Rainbow. So why don’t you relax yer little ponut so we can get through this nice and easy. You want a chance at mah ass, don’t ya?”

The unrestrained lust in Applejack’s voice made Rainbow feel weak. Submission hurt her pride, but it came with the promise of dominance later. With a shaky breath, Rainbow released the tension in her body, and the instant her anus unclenched, Applejack was on her.

Rainbow gasped as Applejack forced her flare past her ring, stretching the pegasus to the breaking point. But Applejack showed no mercy, burying herself up to the hilt with a single thrust.

Rainbow bit her lip hard enough to draw blood, but could not suppress a whorish moan as the bulge of Applejack’s medial ring brushed against a hyper-sensitive area inside her that could only be her prostate. The sensation was unlike anything she’d experienced before, and though it hurt her pride to admit it, she never wanted it to stop.

Applejack was all too happy to oblige, pulling back and thrusting forward again with enough force to dislodge Vinyl from her place at Rainbow’s rump. But her services were hardly needed any longer. Celestia herself could not bring Rainbow to her hooves now.

From a new vantage point, Vinyl watched Applejack’s bucking hips, tingling with anticipation. Every hilting thrust produced a louder squeak from the hopelessly submissive pegasus. Rainbow was selling one hell of a ride, and Vinyl could hardly wait to buy.

Grabbing the discarded bottle of lubricant, Vinyl started to apply it to her rim, but stopped short as a devious idea came to her. Moving as silently as the mattress would allow, Vinyl rounded the scene before her and locked her eyes on Octavia’s unsuspecting rump. Before the cellist suspected a thing, Vinyl’s hoof snuck under her tail and smeared a healthy coating of lubricant on Octavia’s star.

Octavia gasped as the magic of the gel dissolved the contents of her bowels, losing her grip on Rainbow in the process, but the only thing that shot up in response were Rainbow’s spastically twitching wings. Octavia turned to glare at her marefriend, but found her preoccupied with her own anal lubrication. With a sigh, she joined Vinyl a safe distance away from the increasingly-heated rutting of the other two mares on the bed.

“Faster!” Rainbow begged. “Celestia I’m so close!”

Driven by Rainbow’s desperate cries, Applejack found another gear, humping so fast that it hurt. “Buck, Rainbow, Ah’m cummin’!”

Rainbow’s only response was a high-pitched yelp, her left hind leg twitching uncontrollably as her flare expanded and released a torrent of cum onto the sheets below them. Applejack’s peak was not far behind, driving Rainbow up the wall as her warm, thick seed flooded into her ass.

Just as their pleasure bordered on pain, it began to fade. Rainbow’s legs gave out, causing Applejack to collapse on top of her, the impact producing a wet slap, reducing both mares to a sticky, panting mess.

Applejack’s penis began to retract back into its sheath, exiting Rainbow’s gaping ring with a wet pop and a stream of semen that ran down Rainbow’s balls and pooled onto the sheets below.

“Sorry ‘bout the mess,” Applejack managed.

“Don’t worry about it, I learned a spell for this when I was with Strings,” Vinyl stated proudly. “Well, it was for fillycum, but it should still work for this.”

Vinyl’s horn began to glow and wrapped the two spent mares and the sheets below them in a red aura. Then, in a flash, it vanished, along with every trace of sperm in the area.

Rainbow whined as the wetness disappeared from her plot. “Did you have to take the stuff inside me, too?”

Vinyl shrugged. “Sorry, I guess the spell doesn’t discriminate.”

“So, you liked havin’ me take over, huh?” Applejack teased.

“It was pretty awesome,” Rainbow admitted. “But now it’s my turn.”

Applejack grinned, happily presenting herself for Rainbow’s revenge. Already she felt herself getting hard again. Despite all that their buck had taken out of her, Applejack felt fresh and eager for round two.

“Don’t forget about us,” Vinyl reminded, sliding underneath Applejack’s chest and reaching up with her hind legs to rest her hocks on the farmer’s toned flanks. “You’ve got a great figure for this, you know.”

Wrapping her magic around Applejack’s still-flaccid member, Vinyl positioned it against the rim of her needy plot and waited for Rainbow to mount. Octavia flipped over onto her back and positioned her crotch within reach of both submissive parties and received a nuzzle against her ring from Vinyl.

Rainbow took her cue, planting her hooves on her marefriend’s backside and lifting herself up. Aligning her flare with the farmer’s star, she pushed forward, easily penetrating her relaxed ring.

Applejack moaned as Rainbow sunk herself deeper. It was a snug fit, but still allowed her walls room to clench, to the delight of both parties. The ever-changing tightness of Applejack’s plot made it a fight for every nose, but it was well worth the effort. With one last push, Rainbow had no more left to give as the collision of her balls against Applejack’s told her that she was hilted.

While Applejack was distracted by the fifteen noses of hot flesh invading her rump, Vinyl released her magic hold on the farmer’s own dick, allowing it to harden, and in doing so, penetrate the unicorn’s eager ass.

Applejack gasped at the new source of pleasure, but was given no time to recover as, with one smooth motion, Vinyl expertly swallowed every nose Applejack had to offer. Applejack’s eyes rolled back into her head and her tongue lolled out of her open mouth, inadvertently letting it rest on Octavia’s marehood.

Not to be outdone, Vinyl reached out with her tongue to lick down the thin bridge between Octavia’s vagina and anus before delving into the cellist’s rim. Octavia was content to let Vinyl lap at her star, but she had chosen her current position for a reason, and intended to put it to use.

Rainbow made her first thrust against Applejack’s rump, drawing Vinyl’s attention as she matched the motion on Applejack’s length without breaking her lip-lock with Octavia’s plot. On the second thrust, Applejack moved her hips back to meet Rainbow halfway, slipping a few noses out of Vinyl in the process. Vinyl raised her head to complain, but as Rainbow drew back for another thrust, Applejack pushed forward, hilting herself within the DJ once more.

Rainbow did not expect the motion from Applejack, accidentally pulling back too far and popping her flare out of Applejack’s rump. But she caught on quickly, slipping back within the farmer’s plot as her hips thrust out to meet hers.

With Vinyl distracted, Octavia wrapped her tail around Vinyl’s horn and guided it into her plot. Vinyl groaned in pleasure as her horn was enveloped in the warm vice of Octavia’s ass. Two thirds of her fantasy were now coming to fruition, and she felt no need to ask for more.

Once she and Rainbow had settled into a rhythm, Applejack was free to please Octavia. While she bounced atop Vinyl’s horn, Applejack ran her tongue up and down the cellist’s folds, licking as deep as she could reach to heighten Octavia’s pleasure.

Like a well-oiled machine, they rutted away, gaining speed as they went. But unlike a machine, they had their limits. The faster they went, the faster their pleasure built, and it was quickly becoming too much.

Their climaxes went off like a chain reaction. Applejack fell first, and the resulting tightness of her ass sent Rainbow over the edge. Unable to do much else, Applejack locked her lips around Octavia’s clit and suckled on it, bringing the cellist to orgasm. Finally, the cum flooding into her ass and the clenching of Octavia’s plot around her horn became too much for Vinyl, and she joined the others in an explosion of pleasure.

Their voices mingled in a lewd chorus, and though the performance had no audience, none of those involved were the least bit disappointed. For Vinyl in particular it was a dream come true; the initiation of an exciting new sex life to share with her marefriend.

As they pleasure died down, Vinyl was the first to regain her breath. “You know, that didn’t sound too bad. We should harmonize more often.”

Octavia summoned the strength to swat Vinyl with her tail, but the DJ merely laughed through the black strands.

Rainbow sighed, completely sated atop Applejack’s back. “Now this is a spot I could get used to.”

Applejack chuckled. “As long as Ah get a chance at yers, you can have mah ass any day, sugarcube.”

Octavia freed Vinyl’s horn from her rump and scooted back, giving the DJ room to unlock her hocks from Applejack’s flanks and fall to the sheets, reaching a hoof down to rub her pleasantly full belly.

“Do you guys want me to cast the spell again or can I keep this stuff?” Vinyl prompted.

“Well, there’s no real mess, and Ah always like a full belly before bed,” Applejack supposed.

Vinyl smiled. “Great, ‘cause I’m not sure I could cast it again.”

Rainbow didn’t seem to want to move from her perch, so Applejack merely lowered herself to the ground, feeling the pegasus’ flare exit her before she flopped on top of her. “Ah don’t know about y’all, but Ah’m feelin’ pretty tuckered out.”

Octavia rolled back the covers to snuggle in, prompting Vinyl to join her. Applejack was content to sleep where she lie, and judging by the snoring above her, so was Rainbow. Vinyl turned off the light and the four mares fell into a contented sleep.
