Fasten Your Sentry

It had been a rather interesting day in Ponyville. The sun was shining, everyone was going about their business, the colts and fillies were in school, and overall everyone was enjoying themselves like normal. However for two ponies, things weren’t normal at all. For at the Treehouse Library, a purple alicorn gazed through the windows. Princess Twilight Sparkle gazed over at the town where she lived and thought about her life. For all her life she had been looking for a stallion who loved her and took care of her. That afternoon that stallion she had being waiting for had come to her, and had made her day the best of her life. No matter how hard she tried, Twilight Sparkle was unable to stop herself from smirking as she thought of the Stallion who had just finished making love with her and was now showering.

A delivery of a package by Flash Sentry had ended with the two of them making love together on the couch. They had made quite a mess, and they decided to go shower one after another, Flash going first while Twilight insisted on cleaning up using her magic. As she sat down on the now clean sofa waiting for him to finish up in the shower, she imagined how handsome he must look while naked.

After both of them had showered, Twilight suggested they go out for a nice meal together. Although she was thinking the local cafe, Flash Sentry had offered to take her to the poshest restaurant in Ponyville. She accepted gratefully, and they spent the next half hour getting dressed up in the best clothes Twilight had - she wore the dress that was a Birthday gift from Rarity, and she let Flash borrow one of the suits for Stallions that Rarity had also given her, for when Twilight “found a colt-friend for herself”. Although Twilight was cynical about the potential of getting a long term partner at the time - and considering she was nervous around males as well - she was glad now that her Fashion-obsessed friend had insisted and been so generous. To complement the look, Twilight put on a colourful summer hat to hide her horn and Flash put on a pair of rimless sunglasses.

As no-one expected Twilight to wear anything but her Princess’ gown and Flash in his Royal Guard Armour, they managed to get to the restaurant without anypony else taking a second glance. On arriving at the restaurant, they sat down at a table in the dining room that was decorated so ornately in high society style that even Rarity would be stunned. After ordering they spent the next few hours dining on fine cuisine, drinking more wine, and chatting with each other. With every passing moment, Twilight felt Flash Sentry’s attraction towards her grow even greater, and she was happy to see this - she was happy to know that he loved her.

During the course of the meal, Twilight had brought up the topic of her sister-in-law, Princess Cadance. Flash told Twilight he had to report back to her after delivering the package as per normal procedure, but planned to explain his lateness in returning by telling Cadance that Twilight needed him to help organise the library after delivering the book. It gave him a valid excuse to stay with her in Ponyville overnight, and also act as a deterrent for any awkward questions asked about any possible interactions with her by the rumour-spreading guards in the Crystal Empire.

"Oh, you were going to stay overnight?" Twilight asked in response, giving Flash a questioning eye.

"Err yeah..." Flash replied, blushing a little. "I was hoping I could sleep on the couch tonight Twilight, as flying back in the dark is really lonely and depressing" he explained.

"You're not allowed to sleep on the sofa" Twilight responded sternly. As Flash's face saddened, she giggled. "You're sleeping with me in my bed tonight" she added.

A smile grew across Flash Sentry's face. "I'd be honoured to share your bed, Twilight” he replied, looking a little dreamy as he wondered what would happen tonight once they got back to the library.

In the midst of his dreamy thoughts, Flash thought about what had happened that day so far. Doing the things he had with Twilight were beyond everything he had dreamed of, and it had being so far the best day in his whole life for him. However he couldn’t help but still remain suspicious of why Twilight was treating him so well, or why she was being so sexually open towards him. He had disregarded the idea of it being the alcohol, and wondered if what happened in the alternate world between his alter ego and Twilight went further than she had mentioned, and the incredibly erotic activities that they had experienced today was simply a continuation of what they did in the other world of Canterlot High.

One thing he suspected but wanted to deny was that this Alicorn mare he was dining with wasn’t Twilight at all… But she had to be. She looked the same, sounded the same, and was just as kind as Princess Twilight Sparkle was known to be. However in his heart he felt that even if this wasn’t the real Twilight, he didn’t care - he had spent the day with the mare he loved more than anything, and he didn’t want it to end…

They continued talking before finishing their meal and setting off back to the Library. Flash Sentry insisted on paying for their dinner despite Twilight offering to, and after settling the bill they walked back through Ponyville under the full moon to the Library together. As they walked along still talking, Twilight Sparkle looked up at the moon and giggled. She thought about Princess Luna and how she was so helpful. Not just by raising the moon every night either…

No sooner had they entered the library and shut the front door behind them, Twilight had thrown herself at Flash, knocking him down onto the sofa in a loving embrace. They laid there kissing passionately, their bodies pressing together and feeling each other's warmth on their skin. Their attraction for each other was driving them wild, and in each other's minds they wanted nothing else but each other right now.

Flash Sentry broke the kiss and gazed into Twilight Sparkle's eyes. "I love you so much Twilight... I want to be with you forever" he whispered to her.

"I want to be with you too" Twilight whispered back, smiling. "I want to be all yours forever, Flash. Every single one of your desires i'll fulfil just for you" she added, before kissing him again.

Flash smiled, and smelt the alcohol on Twilight's breath. They had both drank a hell of a lot of wine that day, but he felt the attraction between them both wasn't induced by the alcohol at all now. He felt their hearts were joined together by a bond of pure love, and nothing could break them apart. He felt Twilight was sincere when she said she'd do anything for him, just as he wanted to give her anything she wanted. As he thought about what had happened that afternoon, and what he wanted to happen next between him and Twilight, he felt his cock starting to rise again.

Twilight giggled as she felt her lover's erection beginning to emerge. She shifted herself forward so that it had room to rise, before sliding herself backwards so her pussy lips were surrounding his slowly but steadily enlarging shaft. "I see you're turned on by me" she smiled, feeling the warmth of his member against her loins.

Twilight placed her hooves on Flash's shoulders and used them to push herself up into the air. Once she had raised herself all the way up, she leaned backwards so that her pussy lips were now rubbing against the tip of Flash's now fully erect penis. The warmth of her wet pussy on the tip of his cock was too much for Flash. Turned on beyond belief he could take no more, and spontaneously thrusted his hips upwards.

Twilight let out a gasp as she felt his cock slide into her pussy for the second time that evening. She let out a giggle as she felt his huge member part her insides - she still had a very tight pussy and she wasn't used to taking insertions of his size. As she felt Flash starting to pull her down while thrusting his hips up and down with speed, she began moaning with every motion he made, the sensation of getting fucked by him unlike anything she had felt before today.

Less than five minutes passed and already Twilight was nearing her first orgasm, when suddenly Flash pushed Twilight up and pulled out of her pussy. "Why did you do that?" Twilight asked him.

Flash grinned. "Turn around and you'll see" he replied. Twilight turned around like he said so she was facing away from him and her rear was facing towards him. She moved her tail aside so he could get a full view of her butt. "You said you'd satify my every desire, Twilight. I desire to know what your rear entry feels like" he said.

Twilight giggled. "Yes Master, go ahead and fuck my ass as hard as you wish" she replied. As she felt him pull her downwards again, she smiled in anticipation and used her hooves to pull her buttcheeks apart - although she preferred having her pussy fucked, anal sex was a pleasant change from the norm, and she was excited to find out how her rear would take Flash's massive member.

The tip of Flash's cock was pushing against her rear entrance as he pulled Twilight down, and with a thrust of his hips the head of his cock slid with some difficulty into her ass. Both let out a gasp of surprise, Twilight having her ass stretched wider than ever before, and Flash feeling tightness on a level he hadn't experienced with any other mare before. Taking a deep breath, he began thrusting slowly in and out of Twilight's backside, with every thrust another half inch of his member sliding into her. He sped up steadily every time his member slid in, with Twilight moaning in happiness from every thrust as her butt was stretched to the maximum by her lover's cock.

He was barely able to get twelve inches inside her before he had reached his climax. He let out a loud cry as he felt pleasure surge down his spine as his cock flared inside Twilight's butt and sprayed a torrent of seed into her. Feeling him orgasm inside her triggered Twilight's climax as well, and she screamed in happiness even louder than earlier that evening with pleasure flowing through her body as her juices flowed out of her pussy and her rear tightened around Flash's cock.

Her whole body exhausted from the orgasm, Twilight fell over onto Flash’s stomach and faceplanted his soaked chest. Flash kissed her gently on her horn, then used what strength he had left from his orgasm and pulled her gently downwards so she was lying face-up on his stomach, his cock still embedded in her ass. Both laid there panting for a few minutes until their orgasms subsided, before both of them burst into giggles and Flash kissed Twilight's neck from behind her.

He then began to pull out his cock slowly, with it eventually coming free with a small pop, covered in his fluids. Out of Twilight's stretched rear the mixture of his cum came flowing out and ran all over his lower stomach and the couch. But he didn't care, as he kissed her on the neck again. Twilight turned herself around so her and Flash were face to face, before kissing him on the lips passionately once again.

Once both had regained their energy, Twilight insisted once again on cleaning up. As Flash went to shower for the second time that day, Twilight cleaned everything up once again with a flash of magic. She wandered over to the window, her eyes beginning to glow green as thoughts of a less benevolent nature filled her mind. She knew Spike wouldn't be back tonight, which would be perfect as it meant her and Flash wouldn't be disturbed - the last thing she wanted Spike to see was her undergoing sexual activity with a partner that would raise some uncomfortable questions back in the Crystal Empire.

Even if it did happen though and Spike had discovered them both, she wouldn't mind. She would have just gone with the flow and handled the controversy the best she could. In secret, Twilight was a sex addict, and tonight she had experienced pleasures she hadn't even imagined were possible. She closed her eyes and smiled as she realised that she really was truly in love with Flash - it wasn't just another fling like she had thought it would be earlier that day...

Closing all the curtains downstairs, Twilight ascended the stairs swiftly up to the bedroom. She laid back on the queen size bed in a sexually provocative pose and waited for Flash to arrive. When he came in, his hair still wet from the shower, she was laid there rubbing her pussy with one of her hooves and gazing in his direction. "Ready for bed, Flash?" she asked him, giggling.

Flash nodded, smiling. As he walked over to her, he felt his body began to heat up from seeing the love of his life naked and playing with herself on the bed. Twilight giggled as she saw his cock uncover from its sheath once again.

As he climbed into bed with her naked, she gazed down at his member and placed both of her hooves on it. "Theres no way you'll be able to sleep with that - how about I help calm it down for you?" she asked him. Flash nodded, and Twilight flipped herself around so her hind knees were on the pillows and her face was in Flash's loins. She opened her mouth and placed it over the tip of his cock, before she began sucking away at him. She loved how his cock tasted, and couldn't wait to taste even more of his cum before the night was out.

When she asked him to "use" her earlier, she intended it to be all just silly talk. But the more she was next to him and feeling his love for her, the more she wanted it to be a reality. As she continued sucking away at him, she imagined taking him away from the other princesses and running away with him to another place where they could live happily forever after. She felt a nice wet sensation on her pussy and figured that Flash was licking away at her once again. The guy was just so kind and caring and selfless by making sure she wasn’t left out of the fun, she thought to herself.

Soon enough Flash let out a moan as his orgasm hit. Twilight moved her head back as she felt his cock begin to throb and it slid out of her mouth just in time to blow a wad of cum all over her face. She opened her mouth and the next few wads shot inside it, filling her mouth up as she savoured the taste. As Flash's orgasm faded and his cock stopped spraying sperm at her, she closed her mouth and turned around on the bed again. She kissed him on the lips, opening her mouth slightly so some of his cum leaked into it. She then swallowed the mouthful of his seed, and he swallowed at the same time. Gazing at her cum-covered face, Flash began to gently lick it off Twilight's face, before swallowing it all.

Twilight giggled. "I've never met a stallion so happy to drink his own cum" she said to him.

"I did it for you Twilight" Flash replied, smiling. "I'd do anything for you"

Twilight grinned. "Well in that case, I want you to do something for me tomorrow morning" she said to him, and whispered into his ear. He grinned at what she said, and nodded in agreement. They embraced in a passionate kiss one more time before cuddling close to each other and falling asleep laid on top of the sheets in each other's arms.

Meanwhile in Canterlot, Princess Mi Amora Cadenza was pacing up and down looking concerned while unable to sleep. As she wandered through the palace to the kitchen for another drink of water, she crashed into another princess walking down the hallway as well. "What are you doing up?" both of them said to each other.

"One of my guards - Flash Sentry - hasn't returned from a simple delivery mission" Cadance sighed. "With all the troubles in Equestria, i'm worried something bad has happened to him."

The other princess smiled. "Don't worry about it. I'm sure all your guards are able to take care of themselves. Especially Flash Sentry" she replied. "He's probably just sleeping now so he doesn't have to fly back in the dark. Like you should get some rest as well" she suggested.

Cadance nodded. "I'll see you in the morning then" she smiled at the other princess before hugging her and going back to bed.

Although the smaller princess was confident that Flash was safe and well, she couldn't help but feel a little concern for him. She had a special place in her heart for him, and wished he could have been there with her at the summit rather than on a mission...

***

A few hours later and the sun was rising over Ponyville. Twilight Sparkle opened her eyes as she felt the first rays of the sun fall upon her naked body. She tried to stretch out her limbs, but to her surprise they wouldn't move. She gazed at them and saw that all four were tied to the posts of the bed. Glancing around she saw that she was face up with her legs spread in full view of the door to the upstairs corridor. And gazing through the door grinning wickedly was no other than Flash Sentry himself.

Twilight giggled. "I see you got me all ready to service you" she said, wiggling her left front limb. "Only I didn't expect you to want to begin this before breakfast..." she added.

Flash smiled. "Well, you wanted to be in bondage, so I thought i'd best do it as soon as possible for the mare I love the most" he replied. He walked towards Twilight, and she could see between his legs his member was beginning to harden. She giggled, impatient for the rough fucking he was going to give her now she was tied up ready to be used for his every desire.

Flash had forgotten to close the windows, and so it happened that when a special grey pegasus mare flew by, she saw to her shock the princess tied up facing a stallion. She braked heavily in midair, before flying backwards and looking through the window. She gasped as she saw the massive erection the orange stallion had between his hind legs, and how he went on to mount Twilight Sparkle. She got closer to the window and watched silently as he began fucking Twilight's pussy while she was still tied up.

At that point, Derpy Hooves thought Twilight had been captured against her will by a horrible pegasus villain. She did consider flying through and helping out Twilight, but her anxiety issues and general shyness made such brave attempts a struggle for her. However with this on her mind as well as observing the hardcore sexual activity through the window, she lost focus on her vertical stability and with one flap out of sync, crashed against the building and fell through the open window.

Both Twilight and Flash jumped as they saw Derpy crash through the window to Twilight's right. "My bad..." Derpy muttered before getting up, shaking her head, and wandering over. "Twilight... what is going on... are you in trouble?" she asked her.

Twilight looked a little uncomfortable at this question - her eyes flashing green a little. “No there isn’t any trouble, Derpy. Me and Flash Sentry here are just... playing games" she said, blushing heavily.

Derpy giggled. "I assume ones a bit more hardcore than the ones we usually play in our spare time with Pinkie?" she asked her.

Twilight nodded. "Derpy Hooves is one of my playmates, along with Pinkie Pie" she explained. "I've watched... I mean i've played with her and Pinkie a lot"

"What sort of games do you girls play together then?" Flash asked. He had began thrusting in and out of Twilight again as the revelation that Derpy was on personal terms with Twilight made him feel comfortable being seen having sex.

"Derpy is... a Lesbian" Twilight said between gasps as she felt Flash shove his member in and out of her pussy. "Oral... Toys... Girl Stuff..." she moaned.

Derpy nodded. "I was on the way to see Pinkie and wondered if Twilight would like to join. But if you're both busy i'll just go on my own…" she muttered.

"Stay" Twilight said. The last thing she wanted was Derpy saying to anyone that Twilight and Flash were having casual sex under everyone’s noses. "Promise me you'll never talk about this to anypony, Derpy" she demanded. Derpy nodded. “Thats good. Now, before you go to Pinkie, why don't you warm up with us first?" she asked her.

"Sure! Where should I go and what should I do?" she asked.

Twilight smiled. "Fly over my mouth so I can eat your pussy. I haven't had breakfast yet anyway" she said. She silently cursed herself for making that statement sound more malevolent than sexy, but on seeing Derpy smile and flying over to her she was relieved to see she hadn’t detected the darker suggestion in the statement. As the grey pegasus flew over she repositioned herself in the air before pressing her loins against Twilight's mouth.

Twilight began licking away at her outer lips enthusiastically, before pushing her tongue upwards and spreading her friend’s vulva slightly. She then continued to lick harder, while Derpy began giggling in response to the stimulation - anyone who had spent time in the bedroom with Derpy Hooves knew she always had strange reactions to sexual stimulation. In the meantime Twilight was trying not to moan too loudly as Flash continued slamming his cock inside her.

Derpy, still inexperienced in sex when compared to Flash and Twilight, was pushed past her limit by Twilight's gentle licks. She let out a gentle scream as she climaxed happily. She let out light moans of happiness as pleasure filled her and her girl cum poured out of her pussy into Twilight's open mouth. Twilight savoured the taste then gulped it down in one swallow - it tasted even better than she had remembered.

The taste of Derpy's juice with the ongoing rough fucking from her boyfriend Flash was too much for Twilight and her orgasm struck. She screamed with pleasure flowing through her, and her girl juice poured out of her pussy as it tightened around Flash's cock. The extra stimulation was enough to cause a chain reaction and trigger Flash's climax. He roared in pleasure as his orgasm hit, and his cock blasted a torrent of his cum deep into Twilight's womb as pleasure surged down his spine.

Exhausted from her orgasm, Derpy fell again, her butt landing on Twilight's chest. The combined weight of the two mares was enough to make the ropes attaching Twilight to the bed snap, and the three of them fell onto the bed together. As Twilight and Derpy cuddled, Flash steadily withdrew his cock inch by inch from Twilight's womanhood, and as it came free a mixture of their fluids poured out of her stretched pussy. He climbed up on the bed next to the two mares and kissed them both.

Twilight giggled. "Its so nice to have my best friend and my boyfriend together to wake me up on a nice summer morning" she said.

Derpy looked even more confused than normal than this. "Wait... you think i'm your best friend?" she asked. Twilight and Flash both nodded. "Wow... i've never had a best friend before... you've been the closest thing i've had to a friend Twilight..." she murmured.

Flash chuckled. "We're all best friends now" he replied. Twilight nodded in agreement despite her thinking how it might have come out the wrong way, and she had other best friends apart from Derpy. But still, maybe it made things a lot better between the three of them. As Flash and Derpy closed their eyes while still hugging, her eyes flashed green for a second as she thought about how Derpy would make a wonderful "mistress" for her and Flash.

After a few more minutes of hugging, Flash stood up and went downstairs to the kitchen while Derpy used her wings to fly out the bedroom backwards and move into the main room of the library. Twilight on the other hand used her magic once again to clean the bed and herself up fully before heading down to meet the other two. When she got there, Flash had a pot of coffee and was pouring mugs for the three of them. All of them drank it happily, even Derpy despite spilling a little on the sofa by accident.

Flash gazed at Twilight and sighed. "I'm going to have to go back to Princes Cadance. Otherwise i'll be in big trouble" he told them. "I wish I couldn't... I want to stay here with you Twilight. And you too Derpy"

Twilight was stuck for words and she panicked. She couldn't let Flash go now, neither could she risk keeping him there. She tried her best to think of something when suddenly Derpy choked on her coffee. "Why doesn't Flash transfer to guarding you, Twilight?” the little grey pegasus suggested. “You know, he resigns from Cadance’s royal guard then you employ him as your royal guard, Twilight” she added.

Flash Sentry paused in surprise at this suggestion. Derpy Hooves had suggested the best way to be with Twilight Sparkle was to sacrifice his career. Even if he was discharged honourably, there would be so many things that could go wrong and his life could get messed up. But for every single negative thought about it that entered his mind, there was a positive reason that overruled it. After a few minutes of thought he cleared his throat as he came to a decision. ”If thats okay with Twilight, i'll do it. She means more to me than anything" he said, smiling happily.

Twilight grinned wickedly - although this wasn’t the most efficient method of doing things, she would be able to keep her boyfriend here now so she could love him forever and ever. "Okay Flash. You write a letter of resignation, and i'll write one requesting Cadance forgoes normal demotion and discharge procedures" she replied. "Could you take the letters to Canterlot, Derpy?" she asked the little grey pegasus.

"Happy to help out!" Derpy replied happily.

***

A few hours later, Cadance read the letters one after another. She was confused and upset at the same time - Flash Sentry was one of her best guards, and he was resigning suddenly for no reason? The letter from Twilight asking her to honourably discharge him was puzzling as well - why would Twilight intervene in the case of a disappearing royal guard when she was a Princess of another realm?

A knock came at the door and Princess Luna walked in swiftly. "Something wrong, Princess Mi Amora Cadenza?" she asked.

"Yes, i've had a letter from Flash Sentry offering his resignation, and one from Twilight requesting he be discharged honourably" she replied. "Its odd how fast it came though, and how Twilight has taken such a personal interest in his case..."

Luna looked a little disconcerted at this. She knew exactly what was going on, but didn't feel it was appropriate to tell Cadance the true facts of what was happening. "I'm pretty sure Twilight just wants to help him out. She is on good terms with him after all, what with him doing errands for you and her" she suggested.

Cadance nodded. Using her magic, she summoned a roll of paper and scribbled a response on it. "Tell the messenger to take this to Flash Sentry. I'm honourably discharging him, giving him all his outstanding wages and end-of-contract payment, and thanking him for the years of service he has given us" she told Luna.

Luna nodded and took the paper, rolling it up using her magic. "I'll tell Derpy Hooves to return this to Ponyville right away" she said.

As Luna left, one last suspicious fact came to mind in Cadance's mind. If both letters came from Ponyville, how could Twilight have sent it considering she had just departed on the train back to Ponyville less than an hour ago?
