In Which Soarin Pounds Dat Ass
Soarin looked around as he ushered Storm Blaze along the corridor, the two of them taking care not to make too much noise. The hallways of the Wonderbolt compound were devoid of life, save for the occasional security guard who would sweep a torch around in an attempt to deter any illicit nocturnal activities.
Suffice to say, these two couldn’t have cared less about that — but getting caught still wasn’t exactly high up on their list of priorities. They ducked into corridors and hid behind furniture on their journey to Soarin’s room, both of them feeling equally as horny and twice as desperate for release.
Storm Blaze licked Soarin’s cheek. “I feel like the luckiest mare in Equestria right now,” she said breathlessly. “I get to fuck the best Wonderbolt - no, scratch that, I get to fuck the best pony - on the entire Celestia-damned planet.”
“It’s going to be one hell of a show,” Soarin replied. “I just hope that you don’t mind helping me to partake in a little fetish that I have.”
“Are you kidding?” Storm Blaze asked. “I’ve fantasised about having you inside me since I was a teenager! I don’t care about your fetish, I just want to get fucked!”
“Oh, there will be fucking.” Soarin grinned. “Don’t you worry your pretty little head about that.”
They arrived at his bedroom door and went inside, Storm Blaze far too horny to query why it was unlocked in the first place. Soarin turned the light on and opened a closet, rummaging around while she admired her surroundings.
“This is a really nice room,” she said. “But I’m only really interested in the bed. Now, tell me more about this ‘fetish’ you have.”
Soarin closed the door and turned to face her, revealing the cords of rope he was holding. “I want to tie you up,” he said. “And then I’m going to fuck you over.”
Storm Blaze studied the rope for a moment, then shrugged. “I’m about to make one of my wildest fantasies come true, and ride you until you can’t feel your crotch,” she said. “Do you really think that I’m going to back out at the sight of a little bit of rope?” She jumped on the bed. “How do you want to do this?”
“Lie on your back in a sort of star shape,” Soarin replied.
“Like this?” Storm Blaze lay on her back with her hind legs spread as far as they could go, giving Soarin a clear view of her moist pussy lips, and her forelegs held out in a ‘T’ shape.” Soarin nodded and she smiled. “Good. Get to it, lover boy.”
Soarin acted quickly, tying the mare up using tight knots that looked impossible to undo. She was soon tied to the four corners of the bed, completely immobile but still able to look around — in particular at the second stallion who suddenly appeared, exiting the bathroom nonchalantly.
“Ah, Denz, there you are,” Soarin said. “Are you ready to go?”
Denz nodded. “You bet I am,” he replied.
“Wait just a minute!” Storm Blaze cried. “I didn’t agree to fuck two guys, Soarin, what’s the big idea? He can watch, but that’s it!”
Soarin laughed at her. “That’s funny,” he said. “Because I don’t seem to remember agreeing to fuck you, either. All I asked you back at the bar was ‘Do you want to come back to my room and have some fun?’ You’re the one who took that to mean something completely different. And besides… this is fun to me.”
As he spoke, Denz started rubbing a forehoof along Soarin’s sheath, bringing him up to full mast by the time he had finished. He got down on his knees and brought his muzzle to the other stallion’s shaft, taking in the scent of Soarin’s growing arousal. He used his other forehoof to rub his own cock, and soon the two were both sporting throbbing erections which bobbed under them.
“I said I was going to fuck you over,” Soarin said wickedly. “And what better way to do that than to make you watch me fuck this guy?” He looked down. “Well what are you waiting for, Denz? It ain’t gonna suck itself, you know.”
Denz responded by trailing his tongue along Soarin’s shaft, coating it in a thin layer of saliva. He worked slowly, taking time to admire every bump and vein in the mottled length of flesh as he rubbed it gently with a hoof.
“You sons of bitches!” Storm Blaze thrashed against the ropes. “You tricked me; when I get myself free, I swear to Celestia, Luna and even Discord that I’m going to kick the crap out of both of you!”
“Sure you will, sweetheart,” Soarin replied, gritting his teeth as Denz’s teeth gently scraped across his head. “Seriously, Denz? I thought I told you ‘no teeth!’”
“Sorry, Soar.” Denz sealed his lips around Soarin’s dick, stifling a gag as the thick rod reached the back of his throat. He soldiered on and eventually bottomed out, his moans sending small surges of pleasure up Soarin’s spine. He stayed in place for a moment and then drew his head back slowly, a continuous slurping sound filling the room. Storm Blaze strained harder against the ropes.
"You bastards!" she shouted. "You fucking... evil... twisted... bastards, bastards, bastards, BASTARDS!"
“Oh come on,” Denz said as he took Soarin out of him. “You can’t seriously lie there and say that you’re not enjoying this. We do this all the time; right, Soarin?”
Soarin nodded. “Hell yeah we do,” he replied. “And every single time, the feeling of being teased is enough to send the mares into overdrive. I’ve lost count of how many of them came simply from wishing they were in one of our places.” He glared at Denz. “Now... I don’t seem to remember saying that you could talk, Denzy, so I think I’d better remind you of your place.”
Soarin stood on his hind legs, gripped Denz’s head with his forehooves and shoved his cock into his mouth. Denz put his own forehooves on Soarin’s sides, steadying him as he began to fuck his face relentlessly. Soarin easily overpowered the other stallion, forcing him to take each and every inch of his length right down to the hilt. Denz moaned intently at the forced deepthroating, savouring the taste of Soarin’s rod as well as the feeling of his lover’s balls slapping against his chin.
Soarin looked over at the bed, where Storm Blaze had given up the struggle to free herself, and the two locked eyes. She couldn’t bear to tear herself away, watching with some trepidation at her idol pounding away into another stallion’s mouth as though he had been told it held the cure for all diseases.
"Do you like what you see, Stormy?" Soarin asked. "I bet you're wishing that you were in his place right now."
Storm Blaze nodded. “I-I am…” she trailed off.
“Good.” Soarin chuckled and looked down at Denz, who looked up with glee written all over his face. “Ready, Denzy?”
“Mm-hmm,” was all Denz could muster by way of reply.
Soarin increased his speed, his renowned stamina showing through as he fucked Denz’s face with spectacular ferocity. The other stallion didn’t even show any signs of discomfort, a clear sign that he was used to this kind of treatment. He stayed stock still, not wishing to move, as he eagerly awaited Soarin to finish.
It didn’t take long. Denz’s eyes widened as he felt Soarin’s cock flare up, then blushed as thick globs of his seed gushed down his throat. He swallowed frantically, desperately trying not to waste any of the precious substance being pumped into him, while Soarin thrust sloppily to get out as much as he could.
“Fuck yes, now that’s what I’m talking about!” Soarin slid his cock out of Denz’s mouth and sat on his haunches. “Holy shit, Denz, I think that was the biggest load I’ve ever fired off.” He watched as Denz finished swallowing. “You okay?”
Denz nodded. “That was great,” he replied. “Oh, man, it tastes amazing.” He looked over at Storm Blaze, who was bright red. “Well I’ll be damned, she still hasn’t cum yet. This mare is made of stronger stuff than the others.”
“She’ll break eventually,” Soarin replied. “Turn around.”
Denz giggled giddily, turning around and presenting himself to Soarin, who stood up and walked over to the bedside cabinet. Storm Blaze tried to take a swipe at him, but the fact her hooves were still bound meant that the futile gesture was ignored. Soarin opened a drawer and took out a small bottle labelled ‘lubricant,’ before walking back over to Denz, who was wiggling his flank impatiently.
“Hang on a moment, would you?” Soarin laughed. "I need to prepare you, as well as get my second wind."
He opened the bottle and squeezed a small dollop of the lube onto his hoof, then gently guided it to Denz’s waiting starfish. He gasped as the cold liquid made contact, but soon moaned when Soarin began coating his hole.
Once he was satisfied, Soarin started rubbing his cock, soon getting himself hard again, and applied some more of the lubricant to himself. “There we go.” he threw the bottle aside. “You’re lubed up and eager, I’m lubed up and rock solid, and she… well, I guess we’ll soon find out how she’ll react.”
Storm Blaze watched as Soarin mounted Denz, pressed his cock against the other stallion’s sphincter and slid inside with minimal effort or resistance. He hilted within seconds, both of them moaning in bliss at the joining. After a pause, Soarin drew his hips back… and then slammed into Denz with vigour.
“Oh, YES!” Denz cried. “Right there, Soarin, fuck me!”
“With pleasure,” Soarin grunted, just as his cock slid out of Denz’s gaping hole. He quickly used a forehoof to guide it back in, a slick squelch indicating success. “Mm, yeah, I forgot just how loose you are, my little cock sock.”
He grabbed Denz’s flanks, pulling them apart to get a better look at his cock disappearing into and reappearing from the thoroughly used hole. He grit his teeth, slamming himself into his fucktoy with reckless abandon, ignoring the pleasured cries and moans of the stallion underneath him.
Storm Blaze shut her eyes, but the sounds the two were making could not be escaped; moaning, groaning, the shlick shlick shlick of the lubricant, and Soarin’s heavy balls slapping against Denz’s tender nethers all combined to create an orchestra of sex — an orchestra which, in Storm Blaze’s mind, was playing the worst concert ever performed to any audience.
Soarin looked down at Denz’s own cock, which was bobbing in tandem with its owner. Grinning, Soarin reached around and started to gently rub it; a stark contrast to the rough anal hammering he was delivering above. Denz sighed contentedly as he felt Soarin’s hoof touching his cock, a small smile coming to his lips as a warm feeling spread all over his body. From top to bottom, he was experiencing pleasure on an unimaginable scale — and he didn’t want it to end.
“Mmh, yes,” Denz gasped. “You’re amazing, Soar. Don’t stop.”
“Please, do stop!” Storm Blaze begged. “I want to get out of here! Don’t you fuckheads know that it’s illegal to keep somepony imprisoned like this?!”
“But you agreed to this,” Soarin replied. “And Denz here will confirm that.” He thrust roughly into him. “Right, my little fucktoy?”
“Yep!”
Storm Blaze sighed, while Soarin continued to plough Denz’s field. The forehoof he was running along the stallion’s cock was slick with precum, and Denz was biting his lip so hard, he had drawn blood. Both of them wanted to cum, but at the same time, both of them wanted to resist that thought.
And so it was that Soarin forced himself on top of Denz, pinning the small unicorn beneath him, and resumed pounding his tender butthole. He began tugging furiously at the cock he was holding, rubbing it as if a genie would ultimately appear and grant him three wishes. He also bit down on Denz’s ears and neck, as if to assert his dominance, although Denz seemed only too happy to comply.
“Who’s my bitch?” Soarin demanded.
“I-I am…” Denz whispered.
“I can’t hear you!” Soarin growled. “I said, who’s my bitch?”
“I AM!” Denz yelled. “I’M YOUR BITCH!”
“And don’t you forget it,” Soarin said.
Denz moaned as he reached his peak, unable to keep up with Soarin for any longer. His cock flared in the other stallion’s hoof, he tensed up, and then he burst. Soarin grinned as his hoof was coated in a thick layer of cum, the rest of the large load ending up all over his bedroom floor. He let go of Denz’s cock and shoved the cum-covered hoof under his nose. Without even being told, Denz took it in his mouth and cleaned it of his own seed.
“You guys are fucking weird,” Storm Blaze hissed.
“Says the mare who isn’t even getting off at the sight of the legendary Soarin relentlessly pounding a nice asshole,” Soarin replied. “I’m telling you, Stormy, you’re the first one we’ve had whose primary reaction was to threaten GBH.”
“A threat I still stand by,” Storm Blaze said. “As soon as I’m free, you two are getting kicked in the balls so hard, your fucking ancestors will feel it!”
“Whatever.” Soarin turned his attention back to Denz, noticing that he was having difficulty standing. “Looks like this one needs a break. Hang on just a few minutes longer, Denzy, I’m almost done.”
“Take… your time…” Denz panted. “I… can take it.”
“Oh, I know you can ‘take it.’” Soarin chuckled. “Okay, here we go.”
He positioned his hind legs to keep Denz’s from giving way, and quickened his thrusting. Denz panted like a dog in heat, trying desperately not to fall down in a heap and ruin what was supposed to be a joyous moment. He relished in the feeling of his ass being stretched by Soarin’s huge cock, he savoured the sound of balls slapping against him, and he loved the feeling of being pinned and helpless under the other stallion’s weight.
All in all, he was enjoying himself immensely.
And, after a few more thrusts, he was able to add another wondrous feeling to that list — the feeling of being filled up at the other end with more of Soarin’s cum. Denz let out a small whine at the fact it was all over, but that was soon replaced by a warm feeling as the cum flooded his senses.
Soarin pulled out slowly, his softening cock trailing cum all the way out of Denz’s butthole and eventually leaking onto the floor. At that moment, his partner finally gave into the exhaustion he was feeling and fell to the floor — feeling thoroughly used and abused, but full and happy at the same time.
“I’m disappointed in you, Stormy,” Soarin as as he walked over to the bed. “I really thought that you were fun — yet it turns out you have a heart as cold as ice.”
“Oh, well,” Storm Blaze replied sarcastically. “Pardon me for not getting off at the sight of two gay stallions fucking each other silly.” She glared at him. “But the hard part still remains, Soarin — you now have to untie me.”
“You’re right, I do.” Soarin took hold of one of the ropes. “Well, I guess I’d better do that so you can— Denz, grab the other side!”
Before Storm Blaze could wonder what was going on, both stallions had undone the ropes holding her in place against the bed — only to use them to tie her front and back legs together, as though she was a rabid timberwolf.
“Hey, what the—?!”
She didn’t get to complete her sentence as Denz walked over to and opened the door, allowing Soarin to dump her unceremoniously in the corridor. She squeaked in shock and protest, but found herself being ignored once more.
And as she glared angrily at Soarin’s bedroom door, the last thing she saw before it closed was the two stallions exchanging the mightiest of mighty hoofbumps.

I regret nothing.
Thanks to Denz Xavier for commissioning this, and giving me the general idea. I had a lot of fun writing it; whats more, it only took me an hour and a half to do. 
Also, thanks to Gail (The Princess of Floof) for providing additional ideas.
(Upon reading this, Storm Blaze called the three of us 'bastards.')
