Filthy's house was a lot bigger than it looked, a maze of lavish corridors and chambers that wouldn't seem out of place in Canterlot's greatest manors. Of course, what Shining payed most attention to were the three separate kitchens, and he memorized their locations just in case. The bathrooms, too, though more for courtesy than any plan of using them.
After the tour, the two sat down to rest in the sitting room. Shining lay on his belly, taking up most of a very expensive looking divan. As sweat dripped onto the antique cushions, he looked over to Filthy, standing on a coffee table with his rear in the air. Shining stared as his anus flexed a moment, before opening to release yet another roaring blast of foul wind. He was by now acutely aware just how inexperienced a slob he really was.
"How can a pony so small be so smelly?" He asked, incredulous.
Filthy laughed. "A strict diet optimized to cause as much gas as possible. Costs a pretty penny getting some of it imported, but I think," he grimaced as a sputtering *FRRPP* escaped his rear, "It's worth every bit."
Shining's nostrils burned with the rotten stench, and he could feel an erection stirring beneath him. His shaft was currently pressed between his belly and the sofa, meaning that it could only grow inch by painful inch. As he tried to mask his discomfort, his thoughts drifted to Diamond Tiara, and his imagination went wild at the thought of such a sweet little foal at his mercy.
Luckily, Filthy didn't notice.
"Hey Shining, you feeling alright there?"
Okay, maybe he did.
"Just... Holding something in..." The white blob groaned.
"Gonna get it loud and spicy, huh?" Filthy asked.
"Y-yeah..." he gasped, tensing himself even more as a few more inches slid from his sheath. The thought of turning a slim little filly into a useless ball of fat to use as a cocksleeve was really getting him hot now. A few drops of pre slid from his cock, and he only hoped his natural musk would hide it from his friend.
No such luck.
"What's that smell?"
"My... Er... My pits!" He lied, hoping Filthy wouldn't want to check.
Filthy grew a lecherous smile. "Lemme see!" He commanded.
Shining complied, folds of white fat hanging down inches from the flesh of his arms. His unwashed armpits released a smell not dissimilar to an entire gym full of sweaty athletes, though he hadn't actually set hoof in one for months.
Filthy shoved his nose right in, causing Shining to jolt as he savored the hideous stench, but only for a moment.
"So," he spoke with ease, what brings you to town anyway?"
Shining's eyes were screwed shut as his groaning stomach tried to force him to relinquish his gas. Apparently the other stallion hadn't realized the smell was from his cock, which was by now almost at full mast, the tip only inches away from open air beneath him. "My little *grrr* sister lives in t-town, over at the library..." he mumbled, panting as the painful pressure in his cock twitched slightly.
Filthy gasped, releasing his pent-up gas in a single loud BRRAFFFT! "Princess Sparkle? Wait, you're THAT Shining Armor?"
"One in the *grbble* same..."
He scrambled down into a deferential bow. "Y-your highness! I had no idea-"
"Calm down, Filthy," Shining grumbled, still concentrating on the task at hand, "We're friends, right?"
"W-well, we-"
"We're just a couple of gross slobby stallions, doing what comes natural. Now c'mon, I'm almost baked here!"
With the mental image of baking brownies, one of the few things he didn't find incredibly arousing, Shining's cock began to shrink, growing flaccid and returning home to its sheath. Filthy stood up, a little sputter of gas escaping his arse as he stretched. Shining eyed him hungrily.
'And besides, connections with ponies like him are what makes holding court so much fun!'

A few hours later, Diamond Tiara slammed open the door. She had a productive day, making fun of those blank-flanks for flunking a test she herself had passed. Well, she'd actually switched papers with Sweetie Belle, but the end result was the same. She tossed her saddlebag in the corner and trotted upstairs, hearing her father's voice a few rooms over.
"You see, Shining, the trick is to let it go at just the right time."
*FCHRACK!*
Oh Celestia, he wasn't-
The stench coming from the double doorway to the sitting room told her he was.
She burst open the doors and feigned a disgusted expression. "Ew, daddy! Not in front of guests!"
"Don't worry sweetie," her father said, sitting on the table, as he often did, "Mr. Armor here knows all about it."
"Yeah," replied Shining, letting out a loud *BUURP* to illustrate his point. He stared at the girl, her cute pink fur and purple hair painting her the picture of an innocent little filly. Her flank still carried a little baby fat, rounding out her cutie mark slightly.
"Whatever," she grumbled, picking up her bag, "Tonight I'm sleeping over with Silver Spoon, so I'm just here to pick up a few things."
With a harrumph worthy of a maitre'd, she turned around and walked out, kicking the door shut and walking down the hall to her own room. A few minutes later, they heard the front door open and shut.
Shining was mildly disappointed for a moment, he'd always wanted to try a foal, but his attention quickly turned to his friend, the smelliest, most disgusting pony he'd ever met. Surely he'd help.
"Heh, she's a good girl," Filthy chuckled, "Not the smelliest, but she's almost as conniving and nasty as her mother. I'll start teaching her business soon enough." He patted his friend's arm, groping the flabby flesh at the elbow. "So what would you like to do, Shining?"
"Well, I was wondering..."
