Spike, Although...

'Later' turned out to be that night. Upon seeing Spike's glacial pace and allocating the rest of the workload herself, Twilight had completed almost every chore on the list before Spike had come back from his third assignment. As a result, Spike had gotten the rest of the night off, and a quick call to Rarity (they have phones in Equestria somebody look this up I'm sure of it) meant that whatever Rarity had in store for their next visit could be moved up ahead of schedule. Spike even had permission to sleep over, since the weekend was coming up. He intended to take full advantage of that privilege.

What he didn't expect to see, when he knocked at the door of the Carousel Boutique with his customary half-quiet three taps, was Pinkie Pie, smiling at him from the inside of the boutique. He didn't expect to see Pinkie Pie anywhere that day, but she did tend to pop up in unexpected places. Spike hoped dearly that this was simply the delivery of an important party invitation he'd missed earlier. It certainly wasn't 'tomorrow night' yet. Was it?

"Hi, Spikey! Rarity told me you guys were free tonight instead of tomorrow, so I shifted my schedule and made time to come over and hang out! Isn't that great?"

Spike found it hard to stare directly at Pinkie's full-power smile. He stared around her instead, letting the awkwardness he felt every time he showed up at Rarity's mingle with this new type of hesitation and overpower him to the point where moving seemed a far-away fantasy. Spike settled for forcing his head down and staring at his own feet, which looked fine, fair enough, but weren't anywhere near as interesting as Rarity, or the chest of toys she always had pulled out when Spike arrived. That she had pulled out now, as a matter-of-fact, Spike was sure he saw it resting on the table out of the corner of his eye...

Then there was Rarity, peeking out from behind Pinkie Pie, opening the door even wider and smiling that naughty, heart-pounding smile.

"Hello, dear! I trust you found the place alright?" Rarity giggled sweetly, showing more and more often that she was unable to resist a joke when she was already a little drunk on the thrill of knowing more than anypony else what was going on. The same girlish fits she got into when she had Spike bent over, face against the headboard, begging nicely for Rarity to fill him up from behind until he sprayed cum all over the towel Rarity had laid out for him, and usually a little bit past that as well, which Rarity insisted he clean up on his own most of the time, unless she was feeling particularly thirsty.

"Uh, yeah." Spike answered before he had time to realize the question was a joke, and when he did, the feeling of embarassment bubbling in his stomach tripled, sending the butterflies that had taken up permanent residence there swirling around in a powerful localized tornado.

Rarity ushered Spike in at full-blush, shutting the door behind him and, to Spike's relative horror, locking it tightly with a glow of her horn.

"What's Pinkie Pie doing here?" Spike managed to whisper as Rarity ushered him over to the living room arrangement she'd set up, bean-bag chairs and throw pillows and enough blankets and fluffy things that you could pretty much lay down anywhere. She'd even pushed the couch to the side to open up the space in the middle.

And there was a bottle of lube sitting in the center of the circle.

"Well, it seems when we took our leave of Sugarcube Corner, you and I left a little evidence that Pinkie Pie couldn't help but notice..."

"It was sweet, but definitely not from a cream puff," Pinkie Pie added helpfully, popping up from behind and revealing it was impossible to have a private conversation anywhere in her vicinity.

Rarity smiled, but Spike's mouth fell open, aghast that the two ponies were handling this revelation so calmly.

When Pinkie and Rarity saw him staring, they both laughed for a long while, only eventually settling into weakened whimpers and wiping away of tears whether or not they were actually there.

"Oh, Spikey," Rarity said, giving Spike a pat on the head and a kiss there as well, "there's nothing to be worried about or ashamed of. You and I aren't the only ones in Ponyville who like to 'play' this way."

"I love to play!" Pinkie Pie said. She looked Spike square in the face, daring him to question her potential misinterpretation. The second Spike opened his mouth to speak, Pinkie Pie turned and licked Rarity on the side of her face with a giant, long tongue. Rarity giggled, and Pinkie Pie licked again, this time on her neck, then her collarbone, each lap getting less chaotic and more focused, bringing a louder series of moans from Rarity with each one.

When Pinkie Pie stopped licking, Rarity's neck and fur were wet, and she was panting slightly.

Spike was hard already, and he did a poor job of hiding it between his claws.

Pinkie giggled as Rarity reached towards Spike's claws and attempted to pull them apart.

"Come now, Spike... Pinkie Pie's a good friend of hers. You can trust her to be just as much fun to play with as I am."

"Rarity says you like butt stuff," Pinkie Pie said. She tilted her head thoughtfully, then turned around and faced the other direction. She lowered her head and wiggled her bouncy pink butt in Spike's face, and waved her tail over her cheeks to show them off. "Like this?" she asked, her tone helpful and suggestive.

Rarity giggled as Spike's face flushed pure red.

"That, uh... I don't, uh... that is, I mean, I've never, we, uh, haven't..." Spike was explosion of stammers, all while staring deadset at Pinkie's ass, jiggling up and down as she bounced her hips.

Pinkie finally stopped twerking and turned her head helpfully when Rarity tapped her on the shoulder.

"I should clarify that we both like... butt stuff." Rarity giggled as she said the words, somehow delighted in the absurdity of putting her obsession into such simple terms. "That is to say, Spike has a butt, and I quite like it, and when we do stuff, it's usually Spike's butt that gets most of the attention..."

Pinkie Pie nodded with an understanding expression.

"Oh, I get it!" She turned to the bottle of lube, and, though Spike hadn't noticed it before, the small blue plastic toy sitting next to it. Pinkie picked up both the toy and the bottle and held them towards Spike with both hooves. "Wanna have some fun with these, Spike? I bet this blue guy'd look real cute in your little dragon butt!"

Spike didn't have any more room left to blush, so he settled for a meager sounding whimper and clutching his tail in front of his stomach to again attempt to hide his erection. Whether or not that was possible, he couldn't hide from the tingles running through his body everytime his cock so much as brushed up against something, including his tail, and he coudln't ignore the steady volume of precum dripping out of the head of his dick like it was attempting to do the lube bottle's job and then some.

He nodded. The last bastion of attempting to be coy had fallen. And besides—what else had Rarity told Pinkie Pie already anyway? Spike was in the hooves of two greater fates, and he could only pray they'd be gentle when exploring his petite backdoor.

Rarity always had been, though not necessarily because she'd wanted to...

Pinkie Pie surprised Spike by kissing him, open-mouthed, at the same time that she went right for his butt, lifting his tiny tail out of the way and rubbing his cheeks like she was massaging him standing up. Spike was used to Rarity squeezing his butt, but just the sensation of somepony different doing it, even though her touch might have felt similar, it was worlds apart, a difference he could neither explain nor articulate. Pinkie Pie... she was more... playful? She would squeeze in light and hard, like she was alternating in a game to herself, and instead of delighting and drowning in the sound of Spike's pleasure every time he let a moan escape, Pinkie Pie seemed interested in her own pleasure, just savouring the sensation of her hoof running over Spike's tight little backside and making him squeal when she pushed up against his nervous rosebud. Rarity had called it that sometimes before. Spike never understood the metaphor quite properly.

"Pass me those, would you, Pinkie?" Rarity gestured to the toy and lube still in Pinkie's hooves, and after a moment to hear her through the makeout-frenzy, and another to remember how to use her hooves, Pinkie passed the two implements over, and Rarity's diabolical grin took over her whole face.

"Spikey," Rarity said, uncapping the lube with a glow of her horn, "do remember to relax, alright?"

Spike mumbled his reply into Pinkie's mouth. He thought it was an 'okay'.

The lube was chilly, as usual, but Spike was getting used to that.

He was getting used to Rarity's hooves, too, joining Pinkie's and squeezing each cheek before prying them apart, slightly (Spike always washed thoroughly before coming over, better safe than sorry), and staring with longing at his underage entrance. He was almost used to the feeling of the tip of the toy prodding between his cheeks, pushing to gain purchase and make that first difficult half-inch a thing of the past.

Spike was learning to relax in a different way. He was remembering to breathe. The toy slipped in only after a few seconds, and Rarity was unable to contain her excitement.

"My, my," she said as she slipped the rest of the toy in to the base almost effortlessly. "My little dragon has gotten very good after his practice. Hasn't he?"

Rarity rubbed Spike on top of the head, eliciting another muffled moan into Pinkie's mouth. With Rarity's signal, Pinkie finally pulled herself away from underage dragon makeouts, though she didn't look disappointed, as she was surely at least a little prepared for what was next.

Spike, on the other hoof, was finding out the plan each second it happened.

It happened like it was choreographed—once Spike was full up with the few inches that he could take comfortably, Rarity left his butt, as did Pinkie, though she was still on the front end of him. Then Rarity popped up, and both ponies went down to the floor, put their heads in front his crotch, and opened their mouths so wide Spike thought he could see down their throats.

Then they started to lick, and suck, and Spike wondered if Rarity had invested in sound-proofing, for the sake of the neighbours.

"Gaaahhh! R-rarity, that feels... ah!" Spike tried to at least let the girls know he was enjoying their performance, but speaking was a task his brain had relegated to a different dimension, and now there was only space reserved for 'watch helplessly as Pinkie Pie and Rarity drag their tongues up and down the side of your cock and lick up the precum dribbling from the head'. That was a very specific set of neurons, mind, but it was incredibly active, as though it had been training for the job.

Spike's cock was twitching, and so much precum was leaking from the head of his dick that it looked like Rarity had uncapped the lube again and poured it all over his shaft. Pony spit was mixing with the precum, until Spike's little cock was fully-lathered up and slick and ready to go, and that's when his balls clenched and seized and he started shooting cum all over Pinkie Pie and Rarity's faces. And their necks. And chests. And manes. Spike had a good range when he was turned on, and that was a lot lately. Rarity liked to test his virility from time to time by seeing how far he could shoot across the bed after a session of edging, each time getting progressively longer until Spike was squirming all fours and begging for release. They managed to make it to fifteen minutes last time before the poor baby dragon exploded all over himself without Rarity's hooves even touching him.

Rarity and Pinkie both seemed to revel in the white shower, tossing their heads back and moaning as they languished luxuriously in Spike's hot, creamy load. Spike panted and moaned as his balls emptied, and when they'd finished, he fell back and landed on his butt, which made him moan extra loud and coaxed one last extra concentrated shot of cum out of his cock, jostled by a firm knock to his prostate and painted straight across Rarity's beautiful closed eyes.

The pony pair giggled as they opened their eyes and saw each other respectively glazed in jizz.

"You look like a donut," Pinkie Pie said, laughing with strands of white dripping down her cheek.

Rarity smiled and stuck out her tongue.

"I assure you I'd be the most delicious donut you've ever tasted, dear." Rarity extended her tongue even further and licked up a glob of cum that was stuck to her cheek. She held out her tongue with the collected jizz on the center, letting both Pinkie and Spike see it for a moment, before she pulled her tongue into her mouth and swallowed with a hearty-sounding gulp. She giggled again, benefiting every day from newfound definitions of 'lady-like'.

"Huh-wah?" Spike was in a daze, that needed no clarification, but the impossibility of language in his post-orgasm state was funny enough to be worth recording.

Pinkie Pie and Rarity laughed, as they were getting used to, and hugged Spike as he sat, still plugged, on the boutique living room floor.

"Is this what you guys do every night?" Pinkie Pie asked. She laid back onto a set of pillows that was piled up behind her and went 'wheee!' as the pillows scattered around her like she'd jumped face first into a ball-pit... filled with pillows. The laws of physics had a habit of compromising themselves wherever Pinkie Pie was concerned anyway, so don't ask yourself how pillows are able to bounce around like that anyway. Just don't worry about it.

"Not every night..."

Spike and Rarity caught themselves speaking in unison.

"Huh," Spike said. "I thought that sort of thing only happened in cartoons."

"Ooh, you know what I should have said when I opened the door, Spike? I should have said, 'Sorry to butt in!' Wouldn't it have been hilarious if I said that? Spike? Wouldn't it?"

Having Pinkie Pie involved in play-time was evidently going to take some getting used to.
