(Trouser) Snakes on a Train
Wet sleet pelted against the Crystal Express as it plowed through the frozen tundra of the Crystal Mountains, on the first leg of its long journey to Neighcaragua. The trip would take the better part of two days, even travelling at top speed.
Fortunately, the Crystal Express was decked out precisely to make a long journey as comfortable as possible. Not only did it have a luxurious sleeper car with a king-sized bed and shower, but it also had a fine dining car, with its own coffee machine, bar, and tables with comfortable velvet seats of a deep shade of red.
Shining Armour, as was to be expected, was making good use of said dining car. The rush for him to get on the train that morning had meant he'd been forced to skip his second breakfast, and had only had time to wolf down a short stack of pancakes and half a dozen biscuits before leaving the castle. At his immense size, that was hardly enough to make a dent in his diet. Fortunately, the well-stocked dining car allowed him to more than make up for that.
Shining was just putting the last morsel of a bumper breakfast of eggs, hash browns and waffles past his lips, levitating over a napkin as he wiped a spot of syrup from his mouth. Pushing the empty plate to one side, along with two others, he rubbed his massive belly and let out a loud burp.
"Ahh, now that hit the spot," he said to himself, licking his lips with relish. Figuring that relaxing with a full belly was as good a time as any to get some work done, he picked up a dossier lying next to him with the details of his diplomatic mission to Neighcaragua to meet with the president there.
As he did so, he idly wondered where his travelling companion, Flash Sentry, had gotten to. He'd said he would join Shining at breakfast, but was running late. Late enough, at any rate, for Shining to clear three plates of food... which had, admittedly, only taken about ten minutes.
As he opened up the dossier, he discovered to his irritation that several of the pages had fallen out. He realised that he must have forgotten to slide them properly into the folder when he took it with him from the sleeper car, and that they were most likely laying on the floor there.
"Perfect," he muttered, grunting as he heaved his bulk to his hooves. This was no small feat in itself—five hundred pounds of stallion made for a lot of weight to pick up, after all. Fortunately, the amount of muscle Shining packed under all his flab allowed him to manoeuvre without too much difficulty.
Already breathing a little heavily, Shining set off for the sleeper car, his heavy hooves sinking into the plush carpet. Since he'd broken the 500-pound mark, not only had Shining gotten bigger, he'd also gotten softer... and bouncier. Every extremity now jiggled and bounced with every movement he made. His ponderous gut swung rhythmically beneath him, never more than a couple of inches off the ground. His enormous, globular rear end bounced up and down in a way that was utterly hypnotic, ripples being sent across his flanks and his enlarged cutie marks. His blubbery jowls and chins wobbled whenever he ate or spoke. There wasn't a part of him that didn't provide a constant visual reminder of his titanic size. As well as that, his girth made it a difficult task for him to even move through the train. At its narrowest points, he could feel his rump brushing against the walls, threatening to get stuck if he wasn't careful.
Reaching the door to the sleeper car, Shining was just about to open it when he heard a strange sound from inside. Puzzled, he listened carefully, and found that he could make out what it was. It was moaning.
More specifically, it sounded like Flash's moaning.
As Shining listened closer, he found he could make out words from behind the door.
"Mmm... oh yeah... oh f-fuck, Shining..."
Wait, what?
"Oh yeah... take me, Captain, take me!"
Shining flushed furiously as he realised what was happening. Flash was in there doing... something erogenous, at any rate. And he was moaning his name while he did it.
Unable to control himself, Shining found his hoof automatically reaching out and pushing on the door. To his surprise, it turned out it wasn't locked, and he found himself practically tumbling into the room. As he did so, he took notice of three things.
Firstly, Flash was in there on the bed, his own 300 plus-pound frame forming a dent in the mattress.
Secondly, all seven inches of his thick, pink cock were on display, a drip of precum pooling at the head as it quivered slightly.
Thirdly and finally, he had a rather large dildo shoved up his ass.
"Gaaaah!" Flash choked, scrambling to both cover himself and pull the dildo out, more or less simultaneously. As he did so, he managed to fall off the bed and onto his ass, sending his generous flab off jiggling from the impact and, crushingly, leaving him with his legs splayed and his erection on full display. What followed was a silence that seemed to last at least a century, as Shining helplessly gawked at Flash from the doorway.
Finally, Flash broke the silence with a quiet query.
"How much did you hear?"
Shining swallowed. "Ah... enough to get an idea of what you were fantasising about."
Flash's face turned positively crimson as he held his head in his hooves. "Oh, sweet Celestia."
Shining placed a hoof over his mouth, only just managing to contain a chuckle at Flash's predicament.
"I... I'm sorry," Flash muttered, looking at Shining over the top of his hooves.
"Hey, don't apologise on my account," Shining said, smiling.
Flash blinked, not sure if he'd heard right. "Come again?"
"What, did you just forget that you're my and Cadance's personal playmate, all of a sudden?" Shining smirked, stepping into the room fully and closing the door. "We've had enough three-ways since then for me to not find this particularly weird. In fact, I have to say, I'm quite flattered that I'm the one you were fantasising about."
Flash finally removed his hooves from his face, beginning to feel a sense of relief. "So... you're okay with this?"
"Oh, more than okay. In fact..." Shining grinned, his eyes becoming half-lidded as he gave Flash a sultry look. "It just occurred to me that we've never had some one-on-one time with just the two of us. So... how'd you like that fantasy of yours to become a reality?"
Flash's eyes shot wide open, his jaw dropping as his blush returned in full force, spreading as far as his ears. "Wh-wh-wh-whaaaaa?!"
"You heard me," Shining said huskily, moving ever closer to Flash. "We're both adults. Why not have some adult fun together?"
"But, but, but..." Flash stammered. "W-we never... did it with each other before! We always took turns with Cadance!"
"That's true, I suppose," Shining said slowly. "But, you know, I've slept with stallions before."
Flash blinked. "What? You... you have?"
"Mmhmm." Shining moved closer to him, close enough for Flash to feel his breath on his muzzle. "There was a young rookie guard who came to me once, said he was feeling pent up. This was a long time ago, before I started gaining. Well, Cadance and I have always had an open marriage, so I was only too happy to oblige..."
He leaned in even closer, whispering right into Flash's ear as he caressed his plump cheek with a hoof. "By the time I was through with him, I'd pumped him so full of cum that he was ready to pop right out of his armour."
Flash moaned softly as Shining lightly nipped his ear. "And then there was my experimental phase at the academy. All those horny young stallions, far away from any mares, needing some release? You're damn right we got up to some fun there." A hoof went down to Flash's crotch, pressing softly against his shaft. "Oh, those were some good times right there. We rutted each other so hard we could hardly stand. It really helped me come to terms with my bisexuality, actually."
He started lightly rubbing Flash's cock, as he continued whispering. "So, believe me, I'm no stranger to playing for the other team. And I'm certainly not averse to taking somepony as cute as you for a ride. So, what do you say?"
"I..." Flash moaned. "Oh fuck... y-yes..."
"What was that?" Shining grinned, giving the tip of his cock a flick.
"I said yes!" Flash gasped. "Sweet Celestia, just shut up and rut me already!"
Shining leaned in and gave Flash a kiss. "As you wish, hot stuff. Now, up on the bed and assume the position."
Getting shakily to his hooves, Flash clambered onto the bed, his porky hind legs dangling over the edge as he lay sprawled on his big belly. Shining hummed as he brushed his tail aside, getting a look at his balls and hole.
"Mmm-mmm," he purred, leaning in and taking a sniff of Flash's musk. "Looking good, Flash. Looking good."
"Shining..." Flash moaned.
"Right, sorry. I'll stop teasing you," Shining said, grunting as his own member stood to attention. Shining's cock was jet-black and thick, standing at a proud ten inches in length. Flash gasped as he felt its hard length poking at his rear end.
"You ready?" Shining asked.
Flash could only whimper as he bit his lip and nodded. With a grunt, Shining slid himself inside Flash's ass, his belly squishing up against Flash's ass cheeks.
"Sweet Celestia, you're tight!" he grinned, as he began thrusting. Flash gasped as he felt Shining penetrate his rear, sending near-constant jolts of intense pleasure through his body. Both of their flabby frames began to wobble and jiggle as Shining began thrusting in earnest, his own heavy nuts smacking against him with a slapping sound with each jerk of his wide, fleshy hips.
"Ah-ahhh!" Flash moaned, squeezing his eyes shut and grinning delightedly, tears of pure ecstasy forming in his eyes as he was rutted like there was no tomorrow. "Oh, f-fuck me!"
"What do you think I'm doing?" Shining growled, leaning forward and biting on Flash's ear as he redoubled his efforts. "What, you think just because I'm a fatass I can't give you a good ride?"
"Ahhh!" Flash gasped. "Oh Celestia, yes... yes, yes...!"
With how fast Shining was rutting Flash and how intense they were getting, both of them were reaching their climaxes at an increasingly fast rate. Flash ground his teeth almost to powder as he felt Shining pound into him again and again, each thrust delivering more pleasure than the last.
"Oh, fuck," Shining gasped. "I haven't had a lay as good as you in... oh Celestia, here it comes!"
Both of them reached their orgasms at the same moment, crying out in pure delirious joy as they came together.
"Oh, f-fuck meee!" Flash howled, as he felt a pent-up load of hot, thick spunk flood into his rear end, while he simultaneously made a right mess of the bedsheets as he shot his own load. Both of them lay there, gasping for breath, manes plastered to their faces with sweat.
"Oh man, that was intense," Shining panted, smiling widely. "I never pegged you as a screamer, Flash. Flash?"
Flash couldn't answer. All he could do was lay there with a drunken smile, cooing and giggling as he basked in a wonderful afterglow.
Shining chuckled, kissing the back of his neck. "Told you I was experienced."
