The Date

Twilight, Spike, and Glittering Thorax all burst into their collective room, laughing and hanging off one another as they did so. The changeling immediately flopped out onto the large king size bed, while Spike closed the door, and Twilight sat on one of the chairs near the window.

Their shared hotel room only had a single large bed, next to which was a corner table as well as two chairs. Other than that there was only a small minifridge, a cabinet, and an end table. The only other room was the small bathroom they all passed by as they entered.

“That was amazing. I don't think I’ve ever had so much fun on a date before,” Twilight exclaimed.

“I don't think I’ve ever eaten so much love in one sitting before. You guys sure are fans of public displays of affection,” the changeling remarked.

Spike chuckled. “We like letting everyone know that your ours. Isn't that right Twilight?”

“Plus your really cute when you blush,” Twilight added.

Glittering Thorax blushed, and looked down. “Oh you guys. Your going to fill me to the brim at this rate.”

“That can be arranged you know,” Spike whispered huskily.

“You horn dog,” Glittering exclaimed, still blushing furiously.

“Well lets just hold up on that for a few more minutes at least. I still need to wind down from that roller coaster ride,” Twilight stated, the unicorn opening the minibar and retrieving several small bottles from within.

“Oooh good idea Twilight. I wouldn't mind a drink or two while we relax,” Spike exclaimed, flopping down on the seat next to Twilight.

Scooching closer, the changeling perched themselves on the end of the bed. “Oh is that alcohol? I’ve never actually had any before.”

“Is it poisonous to changelings?” Twilight questioned.

Glittering Thorax chuckled. “No. I’m just a bit of a wuss.”

“You’re just too much of a nervous nelly sometimes,” Spike added.

“Unless it comes to horror movies apparently. I can't believe your werent scared when that axe wielding minotaur burst out of the floor,” Twilight remarked.

“It was obvious!” declared the changeling, throwing up their hooves. “They didn't check to see if he was dead, and just left him in the basement.”

“It was a bit cliche at times. Still, I thought the movie was a nice bit of fun between dinner at the Golden Steer and our brief stint at the carnival,” Spike exclaimed.

Glittering Thorax sighed. “Las Pegasus really does have it all. Rides, amazing food, and even a theatre that exclusively plays eighties slasher flicks.”

“And no one even seemed to care that you were a changeling either,” Twilight pointed out. “Though I suppose it helped that a few celebrities have revealed themselves over the last couple months.”

“I’m just amazed that Chrysalis was deposed. She always said that she would do anything to keep her power,” Glittering muttered.

Spike leaned over and rubbed the changeling’s shoulder. “It's alright babe. I’m sure she’s gone for good.”

“Celestia did say that she had her best ponies on it,” Twilight added.

“I know, but those who didn't leave with Chrysalis will be looking to start a new hive,” Glittering explained.

“So?” Spike asked, sitting back in his chair. “Seems like a good idea in my opinion.”

“A hive needs a queen, Spike,” Twilight whispered.

The dragon blinked. “Again, so?”

“I’m the only other candidate,” Glittering muttered, hugging themself as they shivered. “And I don't want to rule anyone.”

“Sounds like you would be the perfect person for the job then!” Spike exclaimed, chugging his tiny beer in several large gulps.

Twilight punched her former assistant in the shoulder. “Spike, Glitter doesn't want that kind of responsibility. We shouldn't push them to make a rash decision.”

Spike rubbed his shoulder. “Hey now it's not like that would even happen right now anyway.”

The changeling sighed. “And thank the first mother for that. I would hate for this wonderful date to end on such a sour note.”

“It's something to consider at least,” Twilight remarked between sips of her cider. “Though I think this is a topic we should save for another time.”

“Yes please. I’d rather go back to you guys teasing me then talking about that,” Glittering muttered.

Twilight and Spike shared a smirk before rising from their seats.

“Oh is that so?” Twilight began.

“Because that can be arranged,” Spike finished.

The changeling blushed. “I err… eep!”

The poor shapeshifter found themselves all but tackled into the bed, with either lover close to their sides. Twilight snuggled into the crook of the changeling’s neck, and nuzzled their surprisingly soft chitin. Spike meanwhile, had spread a clawed hand across his partner’s chest, while also breathing hotly against her Glittering’s cheek.

“You are beautiful,” Spike whispered.

“I uh…”

“Enchanting even,” Twilight added.

“Oh, oh my,” muttered the androgynous changeling.

“I’m glad it was so busy tonight, because it meant we got to show you off to even more people,” Spike declared.

“I kind of like having everyone know that we are dating the prettiest changeling around,” Twilight whispered huskily.

“I…” Glittering blushed even hotter. “I don't know what to say.”

“Then don't say anything at all, and just let us do all the work,” Spike remarked, running a hand down the changeling’s stomach.

“We’ll take care of you,” Twilight whispered, her hoof caressing the underside of Glittering’s chin.

“That does sound nice,” murmured the changeling.

Twilight and Spike exchanged a brief nod before they both began to move lower, trailing kisses down the changeling’s body. The unicorn’s soft, supple lips tickled the proto queen’s side while Spike’s hard claws excited Glittering in a way they couldn't quite explain. Further and further they went, until suddenly the changeling lurched upward, a confused yelp of surprise on their lips.

“W-what are you doing?” they demanded.

“We just thought you’d like to have a little fun,” Spike exclaimed, withdrawing from between the changeling’s legs.

“You aren't opposed, are you?” Twilight added.

“Well I…” Glittering paused. “Just thought that you guys werent a big fan of well… doing it at the same time.”

“I think this proves that we aren't,” Spike exclaimed, gesturing to the changeling’s erect and dripping privates.

“I see that now!” shrieked Glittering.

“Hey, relax. We just wanted to have fun together, but if you are against it we can go back to taking turns again,” Twilight offered.

“N-no!” Glittering quickly retorted. “I was just overwhelmed.”

“Soooo do you want us to continue?” Spike asked. “Because it sure looks like you do.”

Twilight giggled as she glanced at their lover’s budding erection. “Eager aren't you? Usually it takes a lot more teasing before you’re this hard.”

“The combination of having you both here is… electrifying,” Glittering murmured.

“Then should we keep going?” Spike offered.

The changeling bit their lip briefly before nodding. “Just go slow okay? I don't want to get too excited.”

“I’m sure you’ll be fine. We have all night after all,” Twilight cooed, descending between her lover’s legs once more.

“I suppose we do,” Glittering admitted, the changeling slowly falling back to the bed once more.

The dragon wasted no time getting right back to work, his narrow, scaley muzzle planting one final kiss before slipping beneath the changeling’s throbbing erection. The unicorn was just as eager, and gently took hold of her lover’s modest cock, pumping the long, slippery appendage lazily. Then at nearly the same moment, both unicorn and dragon pushed forward, giving their shared lover little time to adapt.

“Oh, oh woooow,” Glittering murmured, their hooves twitching.

Spike’s tongue slipped past his scaly lips as well as the much slimier pair that were nestled between his lover’s legs. Burrowing deep into the changeling’s pussy, Spike’s tongue wiggled this way and that before retracting. Careful not to overwhelm the poor creature, Spike flicked his long forked appendage across his partner’s wet opening.

Twilight mimicked Spike’s actions quite well, her own muzzle descending over Glittering’s cock and swallowing it all in a single go. She didn't remain there for long, and swiftly pulled back in order to fill her lungs with oxygen once more. With that done, Twilight began to gently pump the rest of Glittering’s length while slurping gently on the tip which remained within her mouth.

“You guys are so… this is all,” Glittering murmured, losing track of their words as a wave of pleasure crashed down around them. “Amazing.”

Seeing this as the perfect time to press on, Spike began to deepen the rather intimate kiss once more. This time he didn't stop until the entirety of his nearly foot long tongue had slipped inside his partner. The sheer length of the slippery appendage meant that the dragon could lick the very entrance to the changeling’s womb.

Bolts of lightning shot up Glittering’s spine as they felt Spike molest their most sacred place before withdrawing once more. Their hooves twitched and their entire body trembled, as they were repeatedly made to feel more pleasure than ever before. Then just as they felt like they had managed to get a handle on these new experiences, Twilight’s lips pressed against their crotch.

As if a hidden signal had been sent, Spike extended his tongue at the same time, filling the changeling’s pussy. While Twilight swallowed the entirety of their length, and sucked hard, deepthroating the changeling’s length with ease. It was all too much for the poor hermaphrodite, whose entire body quickly locked up as they unexpectedly orgasmed.

“Cumming!” they shouted.

Both Spike and Twilight remained exactly where they were, the unicorn continuing to suck while Spike twisted his tongue around as best as he could. The affect was pronounced, and immediate, with Glittering moaning loudly as they came hard. Hot slippery changeling jizz shot down Twilight’s throat at the same time as Spike’s muzzle was painted with slightly greenish girl cum.

Though an intense, and full body experience, Glittering’s orgasm didn't last too for more then a few seconds. Just long enough to give Twilight a heaping helping of changeling seed and Spike a good coat of the stuff. Then with a resounding sigh, their shared partner all but collapsed, limbs splaying in all directions.

“That was the most amazing thing I’ve ever felt,” Glittering murmured.

Spike recoiled and licked his lips. “I’m glad you enjoyed yourself.”

Twilight pulled back a second later, swallowing down the last bit of her partner’s cum. “I’m surprised you didn't last for more than a minute. Usually you last at least three times as long.”

“How could I resist? Do you have any idea how good it feels to be sucked and licked at the same time? It's like… I don't even know how to describe it,” Glittering murmured.

“How about we just call it amazing and move on, hmm?” Spike inquired.

Glittering giggled. “Okay. So what next? Did you want to go to that club we saw earlier?”

Twilight blinked, and exchanged a glance with Spike before looking back at their lover. “That wasn't all we had planned,” Twilight remarked.

“Oh yeah we were going to keep going all night,” Spike added.

“You…” Gleaming’s jaw hung open. “Oh wow. I don't know what to say.”

“That you are flattered, and want us to continue?” Twilight offered.

“Well of course. I just didn't see this coming,” Gleaming murmured.

“So you keep telling us,” Spike remarked.

“Err sorry. I guess I’m still a little overwhelmed by everything,” Gleaming whispered.

“Don't worry about it,” Twilight soothed. “Just allow us to take the reins tonight while you just focus on improving that endurance of yours.”

Glittering giggled. “You got it ma’am.”

“That's my favorite little love bug,” Twilight whispered, leaning forward and kissing the changeling.

A second later and the embrace deepened, giving Glittering a taste of their own seed, as well as the faintly sweet taste of Twilight’s love. They parted a second later, though Glittering’s lips were not unoccupied for long, as Spike quickly filled that vacant position. Giving the changeling a taste of her own female parts, as well as the more spicy flavor of Spike’s powerful love.

When next they parted, the slightly love drunk changeling was left reeling, and barely even noticed as they were lifted from the bed. Wrapped in a thin purple aura, Glittering was then turned around and laid atop their unicorn lover, head resting atop Twilight’s chest. Their long, slippery erection positioned mere inches from their partner’s waiting pussy.

“You guys really planned this out,” Glittering remarked.

“Of course we did. Would you have expected anything less?” Twilight pointed out, booping the changeling’s snoot with a hoof.

Glittering’s nose crinkled. “I suppose not but- oh hello.”

Spike settled in atop his lover’s back, his much larger body draping across the chitin clad creature completely. “Hello to you too,” he whispered back, nipping the changeling’s ear.

“Mmm I think I know where you two are planning on going,” Glittering murmured.

“And where is that?” Spike asked as he aligned his own knotted cock with Glittering’s dripping entrance.

“I’m pretty sure you’re going to fuck the hell out of me now,” Glittering exclaimed.

“Such language. We must have really turned you on,” Twilight pointed out, gently grabbing Glittering’s thin, slippery cock with her magic.

“More than you know,” Glittering murmured.

“Then let's not leave them waiting Twilight,” Spike exclaimed, drawing his hips back.

“Sounds good to me Spike,” Twilight replied.

With a single powerful thrust, Spike pushed the pointed head of his draconic cock into Glittering’s waiting hole. Which in turn pushed the changeling forward, impaling Twilight on her lover’s dick. The sensation of both being fucked, and fucking someone else left Glittering a quivering mess unable to even move.

Thankfully for them, Spike and Twilight were more than ready to pick up the slack. The larger of the two drove their hips forward repeatedly while the more magically adept of the pair distracted Glittering with a kiss. Though sloppy, and inelegant the two creature’s make out session was nonetheless as heated as it was passionate.

It only grew hotter when they felt their hips connect, a feeling of utter fullness overcoming them both. Parting briefly, the two creatures shared a moan of ecstasy as their pussies were stuffed with just about all the dick they could handle. Glittering’s slightly larger size allowed them to take the comparatively bigger draconic cock, though not without a little trouble.

The girth of Spike’s throbbing appendage was too much, and the knotted end remained outside of the changeling’s pussy. For now anyway, as the dragon’s insistent thrusts ensured that it was all but assured that he would bury it inside of the changeling eventually. At the moment both parties were happy to feel that rounded bulb push and press against Glittering’s opening, stretching it ever so subtly.

Twilight however, was able to take everything her changeling lover could offer, accepting the thin, prehensile appendage to the base. Though not nearly as big as Spike’s dick, Glittering’s appendage made up for it by twisting around inside of Twilight’s pussy. Stirring up the mare’s honeypot with its dexterous movements, Glittering’s cock was a unique but altogether perfect partner for the plump purple pony.

After that moment of completion, no one moved, each partner quickly coming to grips with the sensations pouring through them. The moment of quiet didn't last long however, as Spike began to drive himself forward once more, dragging Glittering back as he did so. The domineering dragon’s departure drew the changeling’s cock from Twilight’s hole, though it was rammed back inside a moment later.

With a wet slap, their bodies connected again, and Glittering moaned in ecstasy, still coming to grips with the pleasure that rocked their body. A pleasure which only became more potent when they felt Twilight begin to squeeze down around their member. Now reminded of how passive they had been, Glittering did their best to thrust along with Spike when he pounded into them.

They didn't initially reach a harmonious state of pulling and thrusting, though each party was patient. Sure enough it didn't take long for the three creatures to reach that perfect equilibrium, each one reacting expertly to the other’s movements.

When Spike pulled back, Glittering followed and Twilight remained firm, awaiting the moment when her lovers returned. Which happened mere moments later, with Glittering pushing themself forward while still riding the momentum gifted by Spike. The effect was a near simultaneous slap as their bodies connected and two cunts were stuffed with dick.

A trio of soft moans filled the room, with even Spike breaking his usual silence due to how good he felt. The more skillful muscles within a changeling’ pussy meant that Glittering could massage his length in a way no other lover possibly could. Today was no different, and in fact the changeling seemed to be pulling out all the stops, dragging Spike towards his first orgasm.

He wasn't alone either, as all three of the creatures were already nearing the first peak, their bodies growing hot with lust. Sweat dripped down their forms, and their breathy moans became louder, each party quickly realizing what was about to happen. Noone seemed to object, and together they began to race towards the momentous climax they could all see coming.

Their pace accelerated, and the wet slap of their bodies connecting became an ever present background noise. One which was just as constant as the soft, breathy moans that all three uttered whenever they connected once again. Throughout it all Spike’s knotted cock continued to grind against Glittering’s opening, unable to pierce the soft greenish folds.

That was until he threw himself forward with nearly all the force he could muster, forcing the entirety of his dick inside of his partner. Which inadvertently did the same for Twilight, who gasped in surprise as Glittering’s cock bumped against her cervix. A sensation that would have otherwise felt painful, had the changeling not been sporting a more elastic, and pleasurable appendage then most ponies.

The changeling themself wasn't much better off, as the raw pleasure they felt was amplified by the joy their partners gave off. In that instant they took in more love than they had in several of their younger years, though they didn't know it at the time. All they did know was that they were coming harder then they ever had in their entire life, an experience they shared with both of their lovers.

Piping hot cum pumped directly into the deepest reaches of the proto queen’s body and set off a firestorm of pleasure. Which went right down into Twilight in the form of a massive gush of slippery green changeling jizz that splashed against the unicorn’s cervix. Together all three creatures clung to one another, using their shared presence as a life raft while they rode out the greatest high of their lives.

Spike grunted as his knotted cock continued to pump more and more jizz into the changeling’s pussy. Twilight moaned, and shuddered, her hooves clutching tight about Glittering’s shoulders as she too came. Glittering themself pulled their purple lover tight against their chest, while still reaching behind them and placing a hoof on Spike’s shoulder.

Together they came for what felt like minutes, until at long last they could feel the pleasure dull and normality slowly return. In an instant the three creatures realized that no one wanted to let one another go. So with a bit of finesse, and a little magic, they fell to the side, leaving Glittering smack dab between the both of them.

“That was amazing,” Glittering murmured faintly.

“You’re telling me. I think I gave you just about everything I got,” Spike muttered.

“I’m fairly certain I’m leaking you pumped me so full,” Twilight exclaimed while remaining nuzzled tight in the crook of Glittering’s neck.

“I think I’ve got enough love to go live in a shack in the woods for the rest of my natural life,” Glittering muttered.

“Don't tell me that was your end game,” Spike remarked with a smirk.

“I’ve never felt so used,” Twilight added, pulling back just enough to flash her lover a smirk of her own.

“I didn't-” Glittering paused and shot Twilight a frown. “That was mean, and while I’m stuck between you two no less.”

“Yet you love us anyway,” Spike teased, nuzzling the changeling’s cheek.

“Mmm that I do,” Glittering murmured.

“Good, because I plan on loving you for a long time,” Twilight murmured.

“All night to be exact,” Spike added.

Glittering chuckled. “That's nice and all but can we just stay like this for a moment longer?”

“That sounds great,” Twilight purred.

Spike smiled, and wrapped a long arm around both equines, pulling a blanket across all three of them. “Good plan. We have all the time in the world after all.”
