Bi(g) Brother Best Friend Forever

A long last, the end of Heart Flutter's work mandated vacation came and his first shift back at the pet grooming station went by without a hitch and no dogs were nearly drowned. Despite having wings, he felt more content simply trotting home along the lamp-lit sidewalk as the cool night breeze blew through his sweaty mane after a long and tiring yet fulfilling shift. Pleasant thoughts of how wonderful it was to finally be back in the saddle at work danced through his mind as he slowly trotted down the crystal streets with a content smile on his face.

It seemed that he was walking on air without a care in his head. Life is good. He had an amazing job he so loved, wonderful friends and family, a special friend in Shining Armor, and a nice home of his very own. If it weren't for his fatigue, he would have had more of a skip to his trot.

Having not too long ago awoken from a one thousand year slumber, the residents of the Crystal Empire were still used to retiring early for the night, so not a one living soul found themselves joining Heart Flutter as he trotted...or so he would have originally thought. Thinking little of the faint tapping of hooves behind him at first, the tired pegasus resumed his trot as usual until the tappings grew louder and closer. Just when it sounded like a pony was trotting directly behind him, Heart Flutter stopped in his tracks and spun around to see nopony whatsoever.

He would have thought that somepony wished to ask for the time, perhaps simply trot past him as they were in more of a hurry. Instead, it was just him and his own thoughts. Shrugging it off as simply hearing things, Heart Flutter turned back around and continued his trot home, unaware that he indeed was being watched and followed. He would soon find out, for the tapping made a sudden return and the pace was now quickened.

Turning around again, Heart Flutter was again brought face to face with nopony at all. Things were starting to get weird and Heart Flutter was growing more and more uncomfortable by each passing second. As he stood there, his eyes darting off into every conceivable direction, his mane and coat on his back began to stand on end at the odd feeling that he was being watched. The sixth sense that everypony has was tripping off alarms within Heart Flutter's mind and though his wings were tired, he made the choice to exit the scene via air travel.

Now being fifteen feet from the ground and flapping towards home at a decent yet safe pace, Heart Flutter breathed a sigh of relief as there would be a good two out of three chance that whomever was pursuing him would lack the same ability. Judging by the flapping sound of very powerful wings coming up behind him and gaining fast however, he would not be so lucky. Heart Flutter turned around again and unlike the other times, he actually caught a glimpse of the silhouette of a tall pony quickly fading into nothing before his eyes.

Whomever it was had a cloaking ability of some sort and Heart Flutter was about to panic. Before his pursuer could catch up to him he put his tired wings to work and flapped like never before, trying his best to put some distance between himself and the pony following him. He had no idea what their intentions were but he refused to stick around to find out. Instead of making a beeline home however, which was now a mere two blocks away, the swift and clever pegasus took quick right down a main thoroughfare where at this hour, there were still ponies trotting about. Should something happen to him here, he would at least have witnesses and ponies who could possibly come to his aid or call for the authorities.

With every bit of power his wings had left in them, Heart Flutter whipped past trotting ponies as if they were standing still, the sound of wings behind him seeming to be closing in on him. With some quick thinking, he faked a right at the next street corner and whizzed off to the left in hopes of confusing the pony behind him. It seemed to work for a moment as the sound of flapping wings seemed to be going in the opposite direction, but only for a few seconds. He managed to gain some distance but would still need to shake his pursuer as to not reveal to them where he lived.

Heart Flutter proved to be quite the agile pegasus as he dodged oncoming lamp posts and trees in the streets in attempt to escape whomever it was who so badly wanted to catch him. It seemed to be working, but if he had turned around to look back, it would only slow him down and allow more time for the chasing party to catch up. He couldn't look back until he was absolutely sure he had given the other the slip. At this point, he was now feeling the burn brought on by the fatigue in his wings but if he could just push himself a little further down a few more zig zagging streets, he would be home free. Who knows what this pony would do should he or she catch up to him? According to Heart Flutter, that would be a question better left unanswered.

Finally, Heart Flutter reached a point of which not only could he no longer keep going through the air but he couldn't even so much as flap his wings to simply keep himself off the ground. Now that he had no choice but to hoof it the rest of the way home, he could pause a moment to look and listen. Still in a near panic, he took several deep breaths as he looked around to see if somepony was still after him, his ears perked up and flicking in every possible direction. Nopony in sight. That being the case, Heart Flutter wasted no time making a beeline back home, stopping to look behind him every few steps along the way.

Before he would so much as stick his key into the lock on his door, Heart Flutter stood on his front steps to look around and ensure that indeed he had shaken the pony chasing him and was now in the clear. A well deserved and well earned sigh of relief flew from his lungs as he made his way back inside, free, clear, and safe for another day...or so he would have thought until the light in his kitchen suddenly flicked on revealing that he was indeed not alone. Sitting at his kitchen table with a glass of water held to her lips by her blue aura was the last pony Heart Flutter would have expected to see and yet was unsure if he really wanted to.

"Wow, you really made me work up a sweat!" Said a locally familiar pink alicorn in a cheery tone as she sat a now empty glass down. "No wonder Shining's been so spry lately!"

Heart Flutter was speechless and immensely confused. If Shining Armor's wife was aware of what the two of them have been doing when she wasn't around, then why was she seemingly not upset by it? Had he been right all along? Heart Flutter had encouraged Shining Armor to confess his true sexuality to Cadence with confidence that she would still love him but he wasn't prepared for the conversation they were about to have.

"Here, have a seat." Cadence offered as she pulled up a chair for Heart Flutter to sit on.

Upon the request of Princess Mi Amore Cadenza herself, Heart Flutter took his seat across the table from his special buddy's wife and proceeded to nervously twiddle his hooves. He knew he and Shining had somehow been caught he was just about to find out just what she planned on doing about it.

"Heart Flutter, right?" Cadence asked as she extended a hoof for a customary hoof bump. Again, he wisely obliged.

"Y-yes." Heart Flutter nervously replied.

"We've never actually formally met before but I remember you from the crystal fair."

Heart Flutter just nodded in response.

"Heheh, it all makes sense now, you know? A guy checks out Shining's butt and suddenly, he makes an excuse to go off and find you."

Heart Flutter's face was now a shade of red previously unknown to ponykind and Cadence took notice. She wanted him to just relax as he had no need to worry.

"So look, just relax, okay? I know what you and my husband have been doing lately and I'm not angry."

"You're not?" Heart Flutter asked.

"Nope. I mean, I was a little miffed that Shining never told me he was bi but other than that, I was relieved to find out that he wasn't going to some other mare to get some ass. Instead, he takes it up the ass. That...was fun to watch."

"You watched us!?"

Again, Heart Flutter's blush made a sudden return.

"Yeah, I watched you! And that's why I'm here! I want to see more!"

With a huge enthusiastic grin, Cadence suddenly produced a white sheet of paper with her aura and slapped it down on the table in front of Heart Flutter and pushed it towards him. After pausing for a few seconds, he picked up the paper and began reading through the line of the blush inducing things written upon it. Despite having the very Princess of the Crystal Empire sitting across from him, Heart Flutter simply couldn't help but work up even more of a sweat and even allow his stallionhood to receive a sudden supply of hot blood before he had no choice but to cross his legs to conceal an oncoming boner.

"Wha...What is all this?" Heart Flutter stuttered as he began fanning himself with a wing.

"That, my friend, is a list of things I want to see you do to my husband." Cadence replied with heavy breaths. "It'll be a win win for all of us. You get to fuck Shining, Shining get's to fuck you, and I get to watch from the closet.

"Ooohhh wow."

"So here's the deal. You get to pick and choose what you wanna do. You can even say no to any and all of them. I'm not going to make you do anything you're not comfortable with."

"That's...decent of you."

"What do you say?"

Though Cadence gave him every opportunity possible to back out, Heart Flutter couldn't find it in himself to pass up such a deal where he would be allowed to sleep with his special friend any time he wanted with no worry of upsetting the spouse. Being as Cadence and Heart Flutter have only really known each other for a few minutes, the conversation proved rather awkward, at least for the latter. The Princess of love had such conversations with mere acquaintances all the time.

It would only be a matter of time before the two hit it off and before long, they were sharing laughs over a cup of tea while they discussed times and days where they could make their arrangements. Now, Heart Flutter had a funny story to tell his colleagues at work regarding his being stalked and chased by the Princess. Though for the sake of avoiding a visit from his employer's equine resources department, he would obviously be leaving out the parts where he enjoys intimacy with the Prince.

Though both exhausted after a full day's work and a chase to boot, Cadence and Heart Flutter spent the next few hours just getting to know each other and swapping stories about their encounters with the same stallion. Heart Flutter even revealed that on that day that Shining Armor was taking a bath, he was hiding under the water the entire time. Both shared a hearty laugh over that. After getting back on topic however, they finally began putting a solid plan together.

"Okay, so how about Tuesday night?" Cadence asked. "I can give Shining Armor an excuse for me to be 'gone' and you can really give it to him!"

"Cool. I get out early that night and I bet if I let Shining know, he'll take the bait."

"I'll leave what you'll need for it right under the bed. I think you'll both like this one. I've never tried it with Shining before so it'll be fun to watch you two...experiment."

"He seems to like being pushed around so I can't wait to hear the squeals from him when we do this. Hahaha, I can't wait to let him have it!"

"And I can't wait to watch!"

Cadence and Heart Flutter deviously rubber their hooves together as they concocted their plan and thought about the looks they could possibly get from Shining Armor once they took action. What they intended on doing to him once they were in their places and Cadence was hidden in the closet, in their minds, would be the envy of any horny pony. Cadence could leave for the night having made a similar type of friend in Heart Flutter that Shining Armor had.

The next few days came and went and after an anticipated wait that seemed like years, Cadence and Heart Flutter had Shining Armor right where they wanted him. The Princess had previously told her husband that she was going to be at Twilight's for the night which lo and behold, lead him to invite his special friend over just as planned. Just some good, harmless fun was in store for everypony and they could hardly wait. With Cadence now in the closet, waiting for the action to start, Shining Armor trotted into the bedroom with his butt buddy in tow.

"So, whadda ya wanna do tonight?" Shining Armor asked in a low, sultry tone as he picked himself up onto the bed.

"Oh, I think you're gonna love this one." Heart Flutter said in a similar tone, his eyes half lidded and hot blood flowing to his dick. "I've got a special surprise for you."

"Oooohh, you've got me all worked up now. What is it?"

"Just put this on and I'll whip it out for you."

As Shining Armor excitedly tied a blindfold around his head, Heart Flutter reached under the bed where Cadence had placed a special toy they would be playing with, a loose end that had yet to be tied came to light as he glanced over at the closet. If not attended to, this whole endeavor could be blown wide open before the real action really begins.

"Uhh, hold that thought, Shiney." Heart Flutter said as he slipped on over to the closet to consult with Cadence.

Very quietly, Heart Flutter opened the closet door as Shining Armor waited not so patiently while bent over the bed, his rump in the air and his tail raised high. To avoid arousing suspicion, he would have to approach quickly and quietly as to tie up the loose end that could ruin everything they planned for.

"Psst. Cadence." Heart Flutter whispered as he opened the closet and stuck his head in. "I hope you remembered to soundproof the closet. When you start going at it, you might have a hard time keeping quiet."

"Oh...I didn't think of that." Cadence whispered. "Wow, good save, friend."

With the subtle "poof" and small flash from her horn, Cadence cast a spell that would drown out any noise she may make while pleasuring herself within the confines of her closet. Everything was ready for the fun to begin and Heart Flutter wouldn't be keeping Shining Armor waiting much longer.

In Shining Armor's mind, the surprise that was in store for him could have been anything but nevertheless, he couldn't possibly be more excited. Could it be toy of some sort? I shiny new dildo perhaps? Whatever it was, Shining Armor was about to find out and it was anypony's guess if he would actually enjoy it.

From under the bed, Heart Flutter slowly pulled out the big, hard, wooden implement of which he would be using to teach Shining Armor a lesson and get Cadence off at the same time. Heart Flutter had never hit anypony with a paddle before but he was willing to try just about anything once. Just some good, harmless fun that may or may not render Shining Armor's rump a new shade of red. Cadence's mouth watered as she watched her and Shining Armor's mutual friend prepare to give the latter a good whack and their much anticipated wait was finally brought to an end. With a devious grin, he laid a smackdown upon his friend's waiting, begging ass.

Whap!

"Yahahahahow!!" Shining Armor yelped as he yanked his blindfold off and looked back to see Heart Flutter grinning menacingly with a massive paddle in hoof.

Cadence winced as she watched her husband get smacked but not as if feeling his pain, if any. As Shining Armor looked back in confusion, his dick began to slip out of his sheath whether he wanted it to or not. Even if he didn't want to admit it, he enjoyed being slapped on the ass. His friend just had to give it to him a bit more until he fully realized just how much it turned him on.

"Dude!" Shining Armor yelped before being smacked again. "What the fuck are you-OW! I was hoping for like a dragon dildo or someth-AHH!"

"Aww, you don't like it?" Heart Flutter sarcastically whined with a mock pout as he prepared to let Shining Armor have another.

"I...didn't say that!"

Cadence grew wetter and wetter with each smack and with each girly little yelp and squeak from her husband and here marehood was begging for attention that she could not and would not deprive it of. She dug her hoof into her winking pussy and went to town. Her eyes rolled back as she threw her head back and relished in the intense pleasure brought by her own hoof. Though she was not actually enjoying coitus with her husband but according to her, nopony could fuck her like her own self and she was damn good at it. She was so good in fact that she had to slow down a bit as to avoid a premature orgasm.

Though Shining Armor was reluctant to admit it, his dick was at full mast and dripping pre as it throbbed each and every time his ass was whacked. If he truly didn't like it, he would normally attempt to escape his situation, but he put up no resistance whatsoever. The adorable yelps and squeaks coming from Shining Armor were not only driving Cadence mad but Heart Flutter was strangely turned on as well. His own member throbbed every time he brought the paddle down upon Shining Armor who was enjoying being the bitch.

"Thank you sir, may I have another!?" Shining Armor gasped, finally admitting that he loved every second of it.

"Yeah, you like that, you little bitch?" Heart Flutter asked as he drooled over savagely slapping his friend's rump over and over again. "Take it! Take it you little fucking bitch!"

"Yes!! Yes!! Oh fuck yehehehesss!! Ahh!! Ahh!!"

The spanking alone was enough to get Shining Armor off and if he enjoyed that so much, he was about to be driven insane by what was to happen next. Heart Flutter had his own needs and leaving his own cock to be neglected was simply too cruel to imagine so he promptly stuck it into his pony punching bag. Shining Armor was the luckiest stallion alive, not only was be being repeatedly spanked to his heart's content, he was being drilled at the same time. Cadence was immensely enjoying it as well.

"Aaaahhahhhahhh!!" Cadence screamed in the closet as her pussy clenched around her hoof and began expelling fluids with each and every wink. "Ohhhoho fuck!! Gahhh!!"

Once again proving that nopony can do you like you, Cadence sent herself over the edge and mentally thanked Heart Flutter not only for putting on the show but for reminding her to soundproof the closet as well. She couldn't contain her screams even if she wanted to as she continued to soak the floor beneath her and dig her hoof into herself until her arm went numb.

Shining Armor and Heart Flutter could also no longer contain themselves as they both splattered spooge all over each other while the latter gave the former a few final love taps. Both stallions and Cadence were just a bunch of hot messes as they lay hyperventilating in their own sticky fluids and relished in the high. Though he had just experienced pure unadulterated bliss, in the back of his mind, the idea of still having not told his wife about who he really is was burning at him much like before. Unbeknownst to him however, his wife was loving every second if it and still craved more.
