Backdoor Banging in the Baggage Cart

The loud chitter of the various adult students from the School of Friendship filled the train car as they were bright-eyed and talking over each other in anticipation for the field trip to Gallop Canyon. Sitting next to each other and doing their damndest best not to stare at each other too long, or let their debaucherous fantasies of their past endeavors get the best of them, was the young stud Spike the dragon and the co-owner of the Sugarcube Corner: Mrs. Cake. Despite neither of them being teachers that would be relevant for this summer field trip between school semesters, it seemed as though fate ensured that against all odds, the two adulterous lovers would get prolonged time alone for the first time.

Sweetie Belle, the teacher that should’ve been there, had fallen sick with a fever alongside with the other two Cutie Mark Crusaders since they spent so much time together and could easily catch it. Spike was too busy either foalsitting the twins or fucking Mrs. Cake’s brains out, which somehow got him lucky enough to not get sick. Sweetie Belle had asked him through the other side of the door of her sister’s boutique if he could play substitute for one of them, and if he could ask around anypony trustworthy to go along with him. To prevent suspicion, Spike decided to ask both Mrs. Cake and her dumb husband if they wanted to go as chaperones. Before Mrs. Cake could open her mouth to try and persuade her husband to watch the twins while she went, Mr. Cake eagerly volunteered her and insisted on holding down the fort. Whether he was bored with her, annoyed with her, or just didn’t want to go on a trip, Mr. Cake’s quick response boiled Spike’s draconic blood. At least Sweetie Belle had a real excuse not to be with Spike, but Mr. Cake was just quick to get his beautiful wife out of his mane and do his own thing.

Beautiful, Spike’s nostrils puffed out a little smoke before he could stop himself. Though he could barely get any time in with the lovely Mrs. Cake due to their current relationships and responsibilities, Spike found his once purely depraved and nasty thoughts of cheating with Mrs. Cake to be shifting onto a form of comfortability and even downright ownership. Mrs. Cake, the chubby older mare with a fat cupcake-flanked ass resting on the seats, became somewhat of an expectation for Spike’s increasingly primal brain. Like it was commonplace that this sweet and older mare would always be his to play with, fuck, and tease even if she was the one training him. Not only that, but more times would pass where Spike would simply just enjoy the older mare’s company and her extraordinarily sweet personality. He would catch his heart sometimes reacting to her before his loins did, and somehow the purple drake found that terrifying. And this was all before he was magically whisked away on a train with a bunch of students and teachers to another destination free of their partners, and now Spike knew this would be a test to his self-control. Not of his dick, because he knew one way or another, the seductive Mrs. Cake would ensure that he would be milked dry. But of not confessing of falling and catching feelings, because how could Mrs. Cake leave her husband and family when she had a business with Mr. Cake as well? That whole situation seemed set in stone, no matter how dumb or undeserving Mr. Cake was, so Spike tried to swallow those feelings down.

“Good thing Apple Bloom and Scootaloo got that fever too, huh?”

“What?” Spike looked down at Mrs. Cake out of the corner of his eye, seeing Silverstream and Ocellus, the other teachers on the trip, entertaining the students with stories of Hippogriffia and the Hive respectively. Their stories thankfully diverted the class’ attention from Mrs. Cake barely whispering at her dragon pet.

“You know, because if they did come along, we would’ve definitely been caught at some point even if they didn’t see us fucking,” Mrs. Cake explained, and Spike felt an uncomfortable cold jolt rush and leave his body as he briefly scratched his neck with one claw. Mrs. Cake definitely had a valid point, especially considering that the three adult mares had grown up through thick and thin, and could read each other like a book as well as watch their friends and partners like hawks. Even if Sweetie Belle hadn’t asked, Apple Bloom and Scootaloo definitely would’ve spied on Spike’s every movement and look the blue mare’s way like Cutie Mark Detectives, and Spike let out a deep exhale from his dragon muzzle that he didn’t even realize that he was holding in. Mrs. Cake giggled as she patted the tall purple drake’s shoulder with a gentle forehoof.

“Don’t worry Spike, I wouldn’t let your life get ruined like that,” Mrs. Cake reassured him, shaking her head with a small smile. “If anything, I would’ve just not gone on the trip to make sure your reputation wasn’t ruined. I know you could very well be caught for this between us, but I don’t want to blatantly out you by parading around my big blue butt to your face.”

“Really? Thanks,” Spike’s heart flashed a little with that growing warmth that would show up no matter what he tried to do, but seeing Mrs. Cake care so much for his well-being was doing stuff to his mind as it was further shattering his good faith in his marefriend, Sweetie Belle. The white unicorn mare would talk to him, hug him, and even ask how his day was. But she wasn’t as attentive as the baker MILF, not by a long mile. She certainly wouldn’t have bothered to make sure all his needs were met, hanging out with her best buds was usually what she’d do everytime. Feeling an unpleasant twist in his brain from the unwanted image, Spike groaned as he placed a claw over his face. “Urgh.”

“What’s wrong, Spike?” Mrs. Cake asked.

“Just thinking about Sweetie Belle, no, not like that,” Spike huffed, as he rolled his eyes. “She’d get all pissy that she was cheated on, not concerned that any lack of intimacy would be getting to me. She knows I’m a dragon, how could she do this to me? Not the fever, just…”

“Everything else,” Mrs. Cake frowned, nodding her head as her eyes shifted from her normal half-lidded bedroom gaze to gentle care for the drake that was suffering from his trapped helplessness. Similar to Spike, the blue-furred MILF really had grown to care about Spike for not just his youthful stud capabilities, but how considerate and thoughtful he was about her and her family. Minus her limp-dicked husband, of course. Despite her initial interest in keeping together the nuclear family in spite of the setup being inherently at the expense of all her needs, Mrs. Cake felt her once unconditional sweet nature shifting to something more profound and authentic to who she was. No longer was she working endlessly to meet the needs of her family and community, only to get pitiful scraps in return. Now she engaged in more of self-care, whether it was politely asking Pinkie and Sugar Belle to take on more shifts for her, taking long baths, or indulging in her adulterous time with Spike, Mrs. Cake felt her sweetness was reborn and took on a completely new meaning. A lot of that feeling shifted over to Spike now, as he was the only one she’d ever met that actually saw her for how she was and brought great care and sympathy to her struggles, beyond just relating to it. Each time Spike helped, Mrs. Cake just wanted to do the same back.

“Why don’t you tell me about some of the times you were happy before you met Sweetie Belle?” Mrs. Cake asked. “I certainly already know the happy times you’ve had with me, but did you have some great memories beyond your…hatchlinghood, is it called?”

“Yeah, that sounds about right,” Spike nodded, bringing a claw to his muzzle as he continued. “Well, I became an adult during the beginning years of being with Twilight in Canterlot. And with the royal guard and various staff, they ensured both of us had a lot of relaxation off from overseeing Equestrian affairs. Me and her would get to go to the donut shop a lot, and I would obviously bring a lot of gems to put on them. And we’d order half a dozen, sometimes she would have two of them. But we both knew I would eat most of the box.”

“That does sound like a lovely memory,” Mrs. Cake grinned, and Spike’s innocent thoughts about eating donuts shifted to a different fantasy entirely. Speaking of the round puffy sweets, Spike had caught glimpses of Mrs. Cake’s similarly looking dark blue ponut many times when they were either about to fuck or just passing by her. He had ogled his marefriend’s pale gray ponut at times, of course, but Sweetie Belle had joked or downright scoffed at the idea because it would hurt for her. Nevermind the magical lubricant spells or stretching spells that would significantly decrease any discomfort, something Spike knew from studying unicorn sex ed books early on in the relationship. He never brought them up though, especially since he guessed that he’d get a loud scolding from Sweetie Belle if he’d so much as said anything. And since she was a unicorn, Spike knew that she knew already. And it was too much of a gut punch to acknowledge that heavy stone sitting at the bottom of his wounded heart.

“Um,” Spike gulped, glancing at the students next to him and the ones next to Mrs. Cake, seeing them deeply immersed in their own conversations enough to put the purple drake at ease as he spoke up. “Mrs. Cake, is it okay if I uh, ask you something personal about your sex life with your husband?”

“There isn’t much to describe, dear,” Mrs. Cake laughed dryly, the pain of it but a mere twinge in her chest as she shook her head and looked back up at Spike. “But please, go ahead.”

“Have you ever…um…” Spike blushed, feeling sheepish despite the dominance that Mrs. Cake was instilling in him time after time. Perhaps once he got it out there what he was asking for, everything else would fall into place seamlessly. “Have you ever taken it up the ass?”

“Oh!” Mrs. Cake blushed at the graphic question, though she wasn’t the least bit surprised as she smiled. “No, we were the kind of young couple to have sex to have our own family. Don’t get me wrong, we did have chemistry like you wouldn’t believe before I got pregnant, but I didn’t realize how committed Carrot was to no longer prioritizing that after the deed was done. Certainly wouldn’t have crossed either of our minds to bother with the backdoor if my ponut had no use in the equation.”

“Do you think it would…hurt too much?” Spike pried, his reptile heart racing with the hope that he wasn’t pushing Mrs. Cake past what she was okay with. Mrs. Cake opened her mouth, but no words came out as her eyes widened and her ears flickered with realization. She had packed a number of stuff in the hoofbag that rested between the chubby blue MILF and the tall lumbering drake, and through luck, she had packed a strongly effective lubricant despite doubting that she wouldn’t have needed it. Excitement rushed throughout her body as she desperately willed her tail to stay still as she grinned.

“Hmm, I might have something very useful in my hoofbag,” Mrs. Cake narrowed her eyes at the purple drake, before getting up out of her seat and looking to the other teachers as she threw her hoofbag over her shoulders. “Excuse me, ladies. I’m going to get myself a nice hot cup of coffee, hold down the fort for me?”

“Of course, Mrs. Cake,” Ocellus grinned, with Silverstream nodding eagerly before returning to the stories they were telling their students. Mrs. Cake glanced at Spike, but for a brief moment as she winked at him with unspoken directions that the purple drake barely registered before Mrs. Cake hummed and walked out of the cart into the next one. Spike felt his scales go alight with nervousness, wondering what different excuse he was going to have to come up with to convince everyone that he wasn’t going to the same spot as Mrs. Cake. Though, why would they even suspect anything? Even if they had little faith in him for his dragon biology, they all “knew” Mrs. Cake to be a standup pillar of her community, never doing anything wrong and especially not to her family!

Spike scoffed at those assumptions, as he twiddled his dragon claws for a few more minutes before he dramatically stretched out his limbs and gave a sharp-toothed yawn.

“Whoo!” Spike lacked subtlety, the young adult drake knew this, though perhaps he was starting to care less about being caught with each day that passed. Looking to Silverstream and Ocellus, Spike lumbered off his seat and gestured at the door with his long dragon muzzle. “I’m going to use the restroom, I didn’t realize all that food I ate would uh…run right through me. It might be a while.”

“You’re okay!” Silverstream laughed amongst the students making exaggerated faces with their puffed up cheeks and hooves and claws over their mouths. “Just don’t die in there!”

“I won’t,” Spike nodded, turning around and exiting the cart as he had walked through different carts. There was the cafe, the one that Mrs. Cake claimed she would be at even though they both knew she was going somewhere else entirely. He had looked through the bathrooms, though they seemed to be far too small and cramped for both of them to reasonably fit in one. A lot of the carts were crowded, so Spike had no idea which cart Mrs. Cake could’ve possibly picked.

Then, Spike had entered the very last cart of the train: the baggage cart. It had slightly warmer air conditioning than the ones designated for the passengers, and it was filled nearly to the brim with suitcases, bags, and boxes. He could even see various ones meant for the School of Friendship thanks to the clear labels. Then, as he surveyed the rest of the room, he saw a familiar big fat blue dumptruck with a long crimson tail and cupcake cutie marks high up in the air with the rest of the mare’s body hidden behind the baggage. So long as they kept from accidentally destroying the school’s items, the baggage cart was the perfect secluded spot for the both of them. Thanks to their respective excuses, they didn’t have to make it a ruinously short quickie, though they didn’t exactly have all day to get this done either.

Spike lumbered over past the various forms of luggage on all four legs, getting a big grin from Mrs. Cake as she hummed a tune and wiggled the powerful ponut lubricant bottle on one forehoof in front of Spike’s eyes. Spike snorted as he swiftly took the bottle into his claw, feeling less need for formalities, let alone a prolonged buildup to enjoy himself. He squeezed a glop of the glittery lube on one of his claws before pressing them against Mrs. Cake’s dark blue ponut, getting a nod from the blue-furred MILF before Spike grunted and slid three digits in at once with the liquid more than helping to make the sensation feel comfortable. Mrs. Cake gave a shaky moan, almost as if she was getting a prolonged massage, as she shuddered with a wobbly smile from Spike working his magic. He wasn’t even inside her backdoor yet, and Spike was amazed with how tight it felt in comparison to Mrs. Cake’s vaginal walls. Sharp draconic hunger rushed throughout his body, hot flashes in his nostrils to a tingling sensation in his claws, as the warm spark that he felt on and off was fading into the feeling that he was used to. The one that he was more comfortable embracing, as he used his free claw to yank Mrs. Cake’s crimson tail upwards and piston those three purple digits in and out of his mate’s blue plot. Mrs. Cake bit her lip, though a loud moan escaped anyways, as she could barely contain herself. Her normally blue cheeks grew a darker red as she blushed heavily, unable to hold back as she practically brayed with her lustful sounds echoing in the dark baggage cart. Though at this point, Mrs. Cake’s dark blue ponut was being practically fisted by Spike’s dragon fist until he finally determined that he needed to try her out.

Pulling out his lubricated fist and opening his claw, Spike huffed as he slapped Mrs. Cake’s ass and got a sharp eep out of her before he let go of her tail and placed both of his open claws over the blue mare’s cutie marks. He pressed his purple pounder against her, the tip ready to ravage that sensitive backdoor of hers and feeling a sense of elatement from very well being the first one to pop her ponut cherry. Still, Spike looked down at Mrs. Cake expectedly as he tried his damndest to consider her still while holding back his dominant dragon instincts. They were simply leagues more intense than when she had first taken his virginity, to the point of where he had spent plenty of times fantasizing about opening the window to Mrs. Cake’s bedroom and taking her in her bed. Or fucking in the kitchen when everypony else that was working for her was on break, maybe even with her lame husband being out at the counter while they tried to not get caught. Mrs. Cake could let out a really loud noise or two, to risk it and not really give a fuck if Mr. Cake caught them or not. Spike felt lots of smoke spilling out of his nostrils as he felt his vision getting blurry to his own lust, possibly passing out with how much arousal was coursing through his own body. Needing to speak, Spike looked at Mrs. Cake glancing over at him over her shoulder.

“Please, Mrs. Cake, I can’t take it anymore,” Spike whined. “But I need to k-know, that you can handle it. Because I don’t think I can promise to be gentle, not with how much my body is…reacting…”

Spike had fully expected to see Mrs. Cake’s eyes flash with concern, or for the blue MILF to back off from having sex with him entirely. But seeing Mrs. Cake’s deviously wide grin and fluttering eyelashes was the last reaction Spike would’ve guessed by a long mile, and following that with her gliding her glistening ponut up and down his length teasingly was the straw that broke the camel’s back.

“Lean into it, Spi-” Mrs. Cake’s command couldn’t even fully escape her mouth as she threw her head up towards the ceiling and brayed with the sudden thick intrusion of dragon dick entering her backdoor. She hadn’t even so much as played with toys when it came to her backdoor, so feeling the thick and powerful sensation of Spike’s length inside of her was devastating in all the right ways. The lubricant, paired with her own adulterous arousal, did wonders to change what could’ve been a painful experience into a magnificent one. Spike, as he had already expressed, didn’t bother for carefulness either. He had slid nearly his entire length inside Mrs. Cake’s ponut in one go, feeling the walls of her backdoor clamping down on him like a vice. The sensation was everything Spike wanted and more, savoring it for a few more moments as he saw sweat rolling down Mrs. Cake’s blue fur and heard her pant with the desperate need for more. He felt the same, as he pulled out almost his entire length and slammed back into her to hear those melodious deep moans from the older mare as he serviced her with more pleasure than her useless husband ever could.

“Yes, yes YES!” Mrs. Cake brayed, not particularly caring about how much noise she was making in the otherwise empty cart. She briefly worried that there would not only be pain, but there would be too much of it. But that lube she found last minute did absolute wonders for giving her profound pleasure while still enjoying the fucking with a sensation different from when he normally fucked her pussy. Spike plapped with thunderous echoes, caring less each time about the loud noises the less Mrs. Cake cared. If the blue mare didn't care for the possible train worker hearing in the neighboring cart, even with everything she had at stake, then Spike didn't either. His relationship could go down the drain for all he cared.

His eyes widened as he had processed that thought, of not giving a shit if Sweetie Belle was in his life or not. But then again, why was that thought surprising? She barely acted like a real friend to him, and treated him more like eye candy than an actual partner. Her presence in his life seemed expendable, unnecessary. But Mrs. Cake's tight MILF-y backdoor and breeding hole had changed who he was drastically, helping him shed his scales of demure doormat tendencies and actually embrace draconic instincts that made him feel alive and more himself than ever before. He could tell how aroused Mrs. Cake was, with each time his heavy and pent up dragon balls slapped against her sopping wet clit. With each affirmative shout, shudder, or sweat that escaped the beautiful blue mare beneath him, Spike almost didn't notice the worker entering the room and staring at the scene before him like he was staring at a ghost.

Spike couldn’t exactly make out his details to a T in the dimmer lighting of the baggage cart, but his figure didn't look that different from Mr. Cake. Floppy mane, wide blue eyes, shaking like a leaf, the stallion looked like he was trying to calm his nerves. Slowing down, the worker took a deep breath before speaking.

“You two cannot be in he-”

“Rrrrrrrrargh!” The primal and animalistic dragon snarl escaped Spike's mouth possessively before the big purple drake could stop himself, quickening his thrusts as Mrs. Cake didn't tell him to stop. Instead, the blue mare didn't even acknowledge that the worker was even in the room as her eyes rolled to the back of her head and her tongue moved further out of her mouth. He savored feeling her walls clinging to him, her refusal to let her pathetic sham of a marriage stop her from savoring Spike's superior dragon dick, and his ability to assert himself over the worker trying to stop him. Before all this, he wouldn't have even allowed himself to look outside of his own relationship to have his needs met, let alone do so unapologetically at the potential expense of two relationships.

As the worker shrieked like a mare and shut his mouth from saying anything more, Spike opened his muzzle again and bared his teeth. Even in the lack of light in the baggage cart, Spike’s bright choppers shone and put the interrupting stallion in his place. The stallion gasped and turned around, beelining it out of there like a bat out of Tartarus as Mrs. Cake moaned with one final feminine surge of excitement as she came. Marecum squirted on the floor as she felt Spike's knot hitting the rim of her ponut over and over again, causing the purple drake to snarl with his incoming release.

Then, with a shattering bellow that nearly caused Mrs. Cake to piss herself, Spike knotted the blue MILF's backdoor as he felt his thick draconic meat hilt the mare's ponut as he came hot buckets inside. Same as when Spike normally hilted her, Mrs. Cake felt her belly swelling with the level of cum entering her body. As she felt a surge of surprise from her furry blue stomach touching the floor, Mrs. Cake felt a dizzy cum-drunk state take over her brain that made her movements more sluggish. She was slower as she glanced over at Spike with thoughts drifting to her brain.

“Was that…more cum than normal, dear?” Mrs. Cake spoke up as she tilted her head at the realization, starting to blush heavier as she processed the past several minutes. The loser stallion walking in, Mrs. Cake cumming super hard as she imagined the stallion as her own husband as Spike spooked him off. She almost wanted it to happen for real, Mr. Cake getting to see how much he had truly lost his wife due to his own shitty negligence. Or even Sweetie Belle and her pathetic preppy attitude as she refused again and again to help Spike lovingly as a marefriend should.

“Yeah…I think so…” Spike grunted, feeling himself stuck as he realized that they would have to lay in the baggage cart for a while. They could only wait and hope that none of the trip attendants would look for them, let alone find them. At least the worker was threatened into staying quiet.

Spike laid on his side as he held Mrs. Cake against his scaly chest, the minutes feeling like hours as every little sound made him wonder if they'd finally get caught. Though his feelings shifted from concern, to annoyance, all the way to a deep warm smugness in his chest. This mare that was older, wiser, leagues sweeter, had given herself to him and he almost wished more ponies would walk in on them. After a couple more minutes, Spike's knot popped out of Mrs. Cake’s backdoor and the blue mare gasped as she laughed and got up on all fours.

“We're definitely going to get an earful from everybody, huh?” Mrs. Cake giggled. “How about you head back first, play up whatever excuse you made? The students definitely will eat that stuff up, they love stories.”

“Will do~!” Spike felt his voice raise an octave, almost impulsively lunging forward to kiss the blue mare on the cheek before he physically willed himself to walk away from her and lumber out of the baggage cart and into the employee cart. Turning to look behind the counter, he locked eyes with the stallion that had walked in on them. He clammed up and forcibly looked away, shaking still. No matter how depraved he got, how draconic, Spike wouldn't stoop so low as to force other ponies to see him fuck the blue nympho he was growing more addicted to.

Though knowing that the stallion knew what had happened between him and Mrs. Cake certainly made his day~

Getting off the train into the baking dessert that was exceptionally different from the cool and lively town of Ponyville, the four teachers and their several dozen students were given the sight of the tall hotel building that they were all staying at. With how long their respective stories were, the students were so humored and confused, that they had lost any suspicion of the two both being gone at the same time. Spike even came up with a lie to cover up his reason for releasing a loud bellow that everybody within a mile heard, claiming that he had stubbed his toe on a door that closed abruptly on his claw. Silverstream and Ocellus still seemed concerned about the sound, though they were both relieved to see that Spike was okay.

“And so me and Ocellus have a room together with two beds, and you and Mrs. Cake got a room as well,” Silverstream cheerfully explained as she led the group into the hotel lobby, with the demure blue changeling smiling as she glanced at Spike over her shoulder.

“I hope you two don’t mind that, we figured it wouldn’t be weird since you were invited by Spike,” Ocellus explained with a small blush.

“Mind? Of course not, Spike is a trustworthy guy,” Mrs. Cake reassured Ocellus. “Remember? I let him take care of my twins, alongside a lot of other reasons he’s proved to be kind and reliable. He would never take advantage of me, a married mare~”

“Okay? I didn’t mean it like that, just that sharing a room with a guy might be weird…” Ocellus blushed more with embarrassment at her own statement, completely oblivious to how excited Mrs. Cake was rubbing it in the changeling’s face that she’d get to share a room with Spike. No doubt there would be two beds, though Mrs. Cake knew damn well that they would only need one. Silverstream flew towards the receptionist, chatting her up as she explained they were the class from the School of Friendship in Ponyville. The receptionist was barely able to keep up with her, writing really fast on a notepad as Silverstream babbled. Ocellus slinked off to a group of her own students as she took her mind off her embarrassment, while Spike took to Mrs. Cake’s side.

“What was it that they said? You and I will share a room?” Spike grinned with his sharp drake chompers showing as he gently nudged Mrs. Cake’s shoulder. “Well, if we must…”

“You stop that,” Mrs. Cake laughed as they walked up to the counter, the receptionist blushing at the absurdly giant purple drake before giving him the keys to their shared hotel room. They had walked up several sets of stairs, already having the itinerary for tomorrow as the two had the rest of the day to spare to bring their adulterous desires to fruition. They could do anything and everything, while Mr. Cake and Sweetie Belle were none the wiser.

“Maybe I want him to take advantage of me~”

Those were the words that Mrs. Cake had said before she unlocked the door and the door rushed into the hotel room with complete urgency. Spike’s tail had slammed the door closed behind the both of them, as he lifted Mrs. Cake by the ass cheeks with his claws and carried her to the nearest bed. Throwing her on it, Mrs. Cake instinctively splayed her legs out as Spike got hard within mere moments of entering the room as he effortlessly slid his vicious bitchbreaker into Mrs. Cake’s folds, watching as her eyes crossed and she moaned exaggeratedly long and hungrily.

Spike’s teeth flashed as he exhaled smoke, this was going to be fun.
