Two Ponies Come Together

It was no secret that Flash Sentry liked Twilight Sparkle.

Flash Sentry was a bright young stallion from the Crystal Empire, one who had risen through the ranks with ease. He was charming and well-liked by all his fellow guards. He was also the same stallion, who, in a move that everypony nearest to him saw coming, uprooted his whole job and life so he could transfer to the Canterlot Royal Guard to be as close to the newest Princess, Twilight Sparkle. When they’d first met, Princess Cadence had mentioned she saw a sparkle in his eyes that was very familiar to her.

And when the new princess put out an ad for new recruits so she could form her own guard, Flash Sentry was there. He uprooted his whole life again so he could pursue his dream. Of course, he got in. He’d been a guard for years. He had the experience.

Princess Luna knew work and love could never mix. She was older than most ponies. That was just how alicorns were. She knew from the experiences of others that work and love didn’t mix. Admittedly, she didn’t have her own experiences on that front. But Flash Sentry hadn’t learned that yet. He was new to the whole deal. So, after a carefully cultivated friendship, Flash Sentry tried his luck.

Princess Luna stared at the parchment before her. It wasn’t like her to get distracted from work. Piles of parchment sat on her desk beside her. Her bedroom was the quietest place she could finish her work in. She was usually more focused her than any other room in the castle.

Yet, the circumstances were too perfect.

She knew all too well that Twilight had tried to keep it a secret. It was a poor attempt to not hurt Flash’s feelings. Twilight had been seeing somepony. That somepony was a cute little mare she’d met on one of her friendship missions. The two had really hit it off. It was nice to see Twilight so happy for once.

Flash had unfortunately found out in the harshest way possible. He’d stumbled upon one of their… what were the younger ponies calling it these days? Quickies. He’d stumbled on one of their quickies and the rest was history.

He’d transferred back to the Canterlot Royal Guard and was now in Luna’s guard. Though he not a batpony, it was the best that he could do since his old position with her sister had been filled. Princess Luna was more than happy to take him in. Though he was an outcast in terms of race, he got along with the other guards. It was good.

Princess Luna knew that love and work could never mix. However, that didn’t mean that she couldn’t try something different.

A knock rang at her door.

“Come in,” she said calmly.

Flash Sentry entered.

He looked stunning. His mane looked silky and smooth. His muscles were toned and well defined. He was smaller than her but that didn’t mean anything to her. Most ponies were. His ocean blue eyes gave a look on focus only on her well-being. It was his duty after all.

“You wanted to see me, your highness?”

Her sister was known to use her guards for personal reasons. It was no secret that after a good round of cake and a nice bath, Celestia was more than ready to have a second dessert. Special guards were hoof picked for that matter. They could sometimes be heard from the west wing of the castle if one listened hard enough. They were happy to service her.

There was no denying that Princess Luna was equally as attractive. Luna herself hadn’t had great esteem since returning from the moon but through the new method that Celestia had called ‘therapy’, Luna was able to work on her issues. She was able to recognize when somepony thought she was attractive. All her guards saw her as attractive. Celestia even tried to encourage her to go after Icy Spear who was very clearly trying too hard. Maybe she eventually would.

But for now, Princess Luna didn’t want them. She wanted Flash.

Luna knew that love and work didn’t mix. Thankfully, this wasn’t love. Of course, it wasn’t. She barely even knew him. It was just that this her first time doing anything with another stallion, and she was embarrassed to admit it. Before the moon, she and her sister were discriminated against for being alicorns and then they were worshipped as rulers. First others feared her then they feared her for different reasons. Ever since her incident and her return from the moon, public opinion had changed.

She could always just end up with Icy Spear.

Luna didn’t want just anypony. She knew from his dreams that he could be kind and gentle. The way he acted towards Twilight in his dreams was how she wanted him to act towards her. Not somepony rough and cocky like Icy.

Luna needed him to want this too, however.

“Yes, ever since your transfer, you’ve been doing well,” Luna said. She looked him over as he stared back. “How have you been since then?”

“I’ve been well,” Flash said. He shifted a little. “I’ve been adjusting well.”

“Oh really? Tell me about it,” Luna said with an encouraging smile.

“Um well…” Flash said hesitantly. He stared at her for a moment. “It’s been hard, I guess. Princess Twilight had a very specific way of doing things, so I had to unlearn all of her rules in exchange for new ones. And working with batponies has been different from working with other pegasi and unicorns. I don’t think I’ve ever even seen a unicorn batpony until working here.”

Luna appreciated his honesty.

“Have you been trying to move on?”

“How so?”

“It’s no secret that you were clearly interested in Twilight Sparkle. There’s nothing wrong with that, of course. It was bold, I daresay.” Luna said bluntly.

“Oh. That.” Flash seemed nervous for a moment. But his voice never wavered. “I assumed based on a few basic interactions that she liked me. I was wrong.”

“There is nothing wrong with, trying, naturally. Failure is a part of life.” Luna replied simply.

Flash nodded. “That’s right. You asked me if I’d moved on and the truth is that I’m trying to. I’m trying to move on from her.” He sighed but immediately perked up. “It’s not affecting my work, of course.” Flash added.

“Even if it did, you are welcome to take a few personal days,” Luna said, standing. She walked up to him and looked down on him. He stared back, unafraid, yet confused.

She hoped that she could pull this off.

“Speaking of such things, have you ever thought about taking a break from dating to pursue somepony more casually?”

“What do you mean by casually?” Flash asked.

Luna hesitated. She didn’t expect him to ask outright. She racked her brain for an answer other than the blunt obvious one. Yet the answer somehow slid out anyways.

“A hookup.”

She was blowing it. Luna felt her face warm up and she covered her face with a wing automatically. “I-I didn’t mean to be so blunt, I just-”

“It’s fine,” Flash replied. He hardly seemed phased. “I want to try hooking up but I’m more of a romantic guy. I wouldn’t know how to approach a mare for a one-night stand.”

“Truly?” Luna asked in surprise.

“Yes,” Flash frowned. “There’s just some things I’m not good at in life. One thing that’s at least consistent is my job. I’m a good guard.”

“Yes, you are,” Luna practically cooed at him. “Would you know if a mare was approaching you causally?”

Flash stayed silent for a moment before replying. “I suppose not. I mean, I didn’t even know that Twilight didn’t like me. I guess I might be a little dense.”

This was her opening.

“Then I suppose you wouldn’t mind me being blunt with you. I am interested in spending the night with you, Flash Sentry.” She whispered in his ear. “Sexually.”

She wasn’t sure if she’d even said the correct thing. But she heard his breathing pick up. She hoped it wasn’t from fear. Luna didn’t want him to run away but she wouldn’t stop him if he tried. This was all awfully forward.

“I-I-”

“You don’t have to, of course. There will be no harm to your job if you don’t,” Princess Luna replied. “I will forget the whole thing. This will never have happened.” She walked away from him and laid casually on her bed. “But if you come to bed with me tonight, then anything could happen.”

Flash stood, frozen like somepony had cast a spell on him. Then in a blink he was gone.

Luna’s heart dropped. It was wrong of her to approach him, and she knew it. Luna supposed there was always Icy Spear. He was always looking at her flank.

She jumped upon hearing a loud clanking noise and the sound of her bedroom door shutting. She had sent all her usually guards to bed. What had that been?

Luna looked over to where Flash had been and immediately, he flew out from around the corner where bedroom had led out towards her door. Flash was completely nude, so to speak. He had taken all his armor off. That explained the clanking. He’d probably shut her bedroom door as well.

He hadn’t left.

Luna’s heartbeat faster as he approached the bed.

“Shall we?” Flash asked with a wink.

He moved in immediately and kissed her. She melted at his lips on hers and kissed him back. He was so passionate with the way that he kissed her. It was like he had longed to kiss her for as long as she had. He rubbed her chest and bit her lip. She moaned as he did so and reached out to rub his side. Flash moved down, clearly sniffing her and taking in her scent. He began to nuzzle and kiss her neck as Luna moaned and rubbed her legs against him.

Flash could feel his heart beating in his chest. He hoped she would not stop halfway and tell him he was terrible. Though he had some experience, he felt that there was extra pressure to perform well here. She was a princess and much, much older than him. She’d probably been with thousands of stallions prior to him. He had to impress her, especially if there was ever a chance, he could do this with her again in the future.

Her moaning was a good sign. Flash couldn’t help but focus all his effort on her warm, beautiful, honey flavored neck. He wanted to spend more time just nuzzling her, but this wasn’t the time for that. He lightly bit her neck, and she gave a small moan in response. Everything about this made the world around him seem blurrier in comparison. It was just him and her.

Flash still couldn’t believe that he’d ever be doing this with Princess Luna. Every guard who was interested in her was always turned down. Even Icy Spear, a big batpony with more charm and charisma than anypony in all Canterlot, a stallion who probably slept with every maid in the castle and who was always able to woo any mare in a 10-mile radius, even he was turned down. Flash wouldn’t have thought he’d have a chance. Not that he would’ve tried. He usually asked mares out for serious dates, and he didn’t want to make another large mistake and try to woo yet another boss. It was no secret he’d tried to further his relationship with Princess Twilight. He never tried to hide it. Nothing came of it, anyways.

But no more focus on that. He was here, right now, on top of the comfiest mattress he’d ever felt with a very pretty mare. He was going to enjoy himself. This was going to be a night that they’d both remember.

Luna enjoyed every moment of him on her, gently kissing her with the occasional small yet rough bite. She wanted to go further and yet, would he?

Maybe she should take the initiative for once.

She reached forward around Flash and nudged him onto his side. He was breathing as hard as her now. Flash understood. He pulled off her neck and fell over, exposing himself completely. His member was already out. Luna couldn’t help but blush. He was quite large.

Her horn lit up in a blue-ish glow. It snaked around his member and began to caress it. She began to massage it, in the same way she would if it was in her mouth. He moaned quietly as she allowed her magic to do its work. While it pumped away as his thick cock, she brought her mouth to his wing and began to work on it, licking it and sucking it with her mouth. She’d never done that before, even with her own wings beyond preening so she hoped he liked it. Luna couldn’t tell if what she was doing to his wings was stacking on top of the pleasure, he was gaining along with the magical blowjob she was giving him, but Flash seemed to like it, nonetheless.

Flash was in a world of pleasure. The magical blowjob was like a real one but similar enough that he could barely notice a difference. He panted and moaned as she licked and kissed his wings. She was delicate which was good. He’d lost a few feathers in the past from some rougher marefriends. He supposed it was because she was alicorn and had her own wings.

Flash clutched the blanket as he gradually felt himself approaching his big finish. He thrust into the magic though it was unnecessary because it was moving on its own anyways. Despite that, he could not help himself but do it anyways. It was just instinct.

“Oh goddess, Luna!” He cried out. His wings stiffed and he moaned loudly. His orgasm was better than a lot of previous ones he’d had, due to the extra stimulation. He came loudly, his mind blanking and his moans louder than he knew.

His back arched and his cock throbbed. Flash came, his cum spurting out like water from a hose. But instead of hitting the bed, it poured out into her magic hold which collected it. It then disappeared, into an unknown place, a place far beyond his knowledge.

Flash wasn’t really paying attention. He was still wrapped up in the amazing feeling of his orgasm. As he let the feeling wash over him and slowly fade, Luna let go of his wing and it collapsed on his side. He was tired yet felt a newfound energy flood into him. He was going to help her enjoy this just as much as he just had.

He lifted himself off the bed and met her eyes.

“You’re beautiful,” Flash whispered before kissing her again. This time, it was slower yet still equally as passionate. But it gave him a chance to think between the grogginess in his mind and his slowly re-hardening length. How was he to go about doing the main act? She was a princess, so Flash felt like there was an expectation to get this perfect. However, something told him that she wouldn’t really like what he went with.

Luna pulled away before he could come up with a solution. She was breathing as hard as he was. She began to kiss his neck and he groaned. He could without doubt go again. No, never mind about any of that! How could he let her do all the work? Despite this being a situation that was far more intimate than he ever intended to be in with her, he was still a guard. Her guard. He couldn’t allow himself to let her only attend to him. He stood up moved around to behind her.

Luna rolled onto her back; her wings spread out beneath her.

“Could you…um…” Luna found it hard to find the words somehow.

She stared at Flash who stared down at her marehood with such a passionate intensity that she stopped herself. He knew what she wanted and yet he didn’t dive in immediately like she thought he would. She felt completely exposed, in a way that she never had before. It made her feel vulnerable but in a good way. As long as it was with him.

Wait, as long as it was with him?

Before she had a chance to process that thought, Flash began to kiss her, going around her marehood and seemed to deliberately avoid the area. Flash massaged her cutie marks and continued to kiss her. Was he drawing things out deliberately? Then, feeling of his warm tongue on her marehood made her gasp in surprise.

Luna gotten herself off previously. She always imagined the warm tongue of a hot stallion making her feel things she’d never felt before. Now, her dream had come true, but no amount of imagination could have prepared her for what it really felt like to be pleased by a stallion. Not even the shallow orgasms she achieved by sliding herself against her hoof could compare to this.

Every single time her licked at her marehood, she moaned. The pleasure she felt was unimaginably better than anything she’d experienced prior. He was experienced, that much was clear. He was eager to make her feel what he had no doubt felt from her. His gentle actions were providing her a great amount of pleasure and she made sure that he knew that.

The pleasure flooded her mind. Flash’s tongue was slurping at her like she was the best meal he’d ever had. It darted all around her marehood, even dipping inside and caressing her inner walls. He alternated between kissing around her slit and licking it.

Then when she thought it couldn’t get any better, it did. Flash sucked on her clit. The feeling alone of him sucking on her most precious spot let her reach a new height of pleasure she never even dreamed possible. He began to roll his tongue around it and suck on the area forcefully. This, in combination with everything else he was doing, was enough to allow her to reach her peak.

It was a good thing that she had sent all her guards away because she moaned so loudly it was practically a scream. Goodness, this felt better than anything she’d ever felt in her life. And she’d been alive for a while.

Luna was getting lost in the moment but there was also a feeling, one that she was very familiar with. She was getting very close to a very big orgasm. Her wings flapped randomly, and she squirmed while she cried out. She was getting very close.

Flash seemed to sense that she was close and went for the big finish, paying more attention to her clit than anywhere else. And it worked.

“FLASH!” Luna cried out as her orgasm hit her.

Luna came, her back arching and her wings tensing up. She grabbed her blanket while she shuddered as pleasure rolled over her like wind over hills. Her mind exploded and the room went white. There was no denying that she was screaming now, screaming out along with the ride her orgasm took her on. She nearly lost consciousness as she began to come down off the ride but refused to allow herself to. There was still a main event to get to.

Luna felt Flash get up and settle himself on top of her. She could feel his hard, warm length pressing against her and could feel its warmth pressing against her wet slit. She moaned as he gently peppered her neck with kisses. There was something comforting about his weight on top of her, despite their size difference, and there was something sweet and almost romantic about the way he kissed her. She could feel his heart beating quickly and his excited, panted breath on her neck.

“OoooHhh Flash,” She moaned. He held all the cards now, especially in this position.

“I’m here,” Flash replied.

“I-I want you,” Luna moaned, though she was a little surprised at herself for such a line. It seemed cheesy, like out of those romantic flicks Celestia had lent her. Flash didn’t seem to mind, however.

“I know,” He whispered back.

Flash shifted a little over top of her before beginning to slide into her. She was slick, warm, and tight. It was amazing. He almost caught himself drooling a little onto her. He heard her moan as he entered her. It was easy to slide in all way. He stopped allowing himself to feel being inside her. This was her first time, not his. It was easy to forget that with how amazing being with her felt. But he wanted to make her happy.

He wasn’t even sure why that was. Of all the princesses, he’d had the fewest interactions with her initially. Then she became his superior and the one he’d sworn to protect. Even then, he had few interactions with her. Even though he could have let loose right then and there and just railed her until he came, Flash didn’t want to. Maybe he cared if she had fun too.

He wasn’t used to casual hookups anyways. He was more about making his partners happy. That was it. He just wasn’t used to going to town unless he knew the other mare was happy too.

He hoped that Luna was enjoying every second of the act. He started to slide into her. There was some resistance somehow. Her face seemed to clench up as well but relaxed once he was all the way in.

“Are you ok?” Flash asked, wondering if there was something he was missing.

“It’s my f-first time,” Luna replied to his look of confusion.

Flash’s whole world shattered for a moment. Her? Luna was supposed to be thousands of years old, according to every book he’d read about her. Yet she hadn’t had sex at all within that time? Yes, she was trapped on the moon for 1000 years, she’d probably should’ve at some point. And yet she hadn’t. It was such a wild concept that Flash felt was slipping out of his reach with each passing moment and slowly, an urge to thrust into her replaced it.

He shook his head. Flash didn’t have time for this. He thrust into her as slowly as he could. He wanted to make the moment between them last, since despite this being her first time somehow, it was going to be the only time they could come together like this.

Flash wondered what he could do to better help her enjoy it. He could grab her mane and pull it, but then again only some of his marefriends liked it when he did that. He could bite her neck but only some mares were into biting. He could… he could just ask what she was into, he realized.

“Is there anything I can do to… enhance this moment for you?” Flash asked, trying to find the right words between thrusts.

“Um.” Luna hesitated. “Just… just kiss me.”

It was a simplistic order. Flash was not about to let her night be so bland. However, he would not disobey her orders either. He leaned down and began to dot her neck with kisses while he steadily thrust into her. Luna’s moans soon became a steady tune that filled the room. Yet Flash was not content with merely kissing her.

Neither was Luna it seemed because he felt something beginning to caress his wings. Her magical touch was back, and it was all over his wings this time. It felt the same as if her own mouth was touching him. He wanted nothing more than to relax into the feeling and pump into her until he reached the finish line. However, he refused to let that be the case. Instead, he leaned forward and clamped his mouth around her horn.

It was completely unexpected. Luna hadn’t known he would do something like that. However, the pleasure she felt from his warm mouth just being around her horn was enough to let her know that she wasn’t about to let him stop. She magicked some pillows under her head to prop her head up and give him easier access to her horn.

“Please don’t stop,” She moaned. “Please!”

He began to suck and lick at her horn like it was a lollipop while he thrust into her. Luna couldn’t focus on the spell that was stroking his wings and it sputtered out. Not that it seemed to matter. Flash’s wings were stiff and spread and was clearly enjoying the act.

She was absolutely screaming now from the pleasure from her horn and the pleasure of him in her. His cock was quite big, and it felt even bigger inside of her. It was all so good, and she wouldn’t wish it to stop for nothing. She couldn’t think because there was nothing now except the pleasure and the feeling of Flash all over her. It was everything she dreamed of and more.

Flash was having an equally great time. Well, it was a little less than the magnificent time that Luna was clearly having. Her eyes had rolled back, her body was shaking, and her slit was throbbing around his cock. She was going to orgasm soon again and for some reason, he wanted to time it so they would orgasm together. He began to speed up, slamming into her with a force he didn’t know she had. It brought him pleasure to see her having the time of her life.

Flash felt himself beginning to hit his peak. He saw the signs in her that she was going to as well. However, the chances he would pass out afterwards were very high so if they were not going to go at the same time then she would need to cum first.

He sucked hard on her horn and then suddenly let go and leaned into her ear.

“I want to cum with you,” He whispered.

“T-then cum and I will cum with you.” Luna replied.

Flash immediately began sucking her horn harder than before. He thrust into her faster and faster until he made two last hard thrusts and pushed his throbbing cock into her and came. He could feel her orgasm as well, as her horn let out familiar sparks and the delicious magical juice that only a unicorn or in this case, alicorn, could make. It tasted like a sugary tropical juice from a certain resort at a beach he’d never been to.

Luna came as well. She’d reached her peak when she felt his last thrust into her and his warm cock throb inside her for the last time. Her wings flapped in unison with his and she gripped the sheets in a final scream of pleasure as her mind exploded as well as her horn. Her back arched and she felt her horn explode and her horn juices drip down the side though Flash was quick to drink it all up.

His whole body shuddered, and his wings flapped hard, though lift off would not be possible with her him inside her. He made sure of that, as he emptied his balls into her, the last of his cum coating her walls in a thick white. He pulled out with a pop and collapsed onto her.

Flash pulled his mouth off her as Luna was finishing and she sank back into the bed as her orgasm subsided. They both lay there panting and Flash rolled off her.

“That was… something else,” Flash said, though he could barely keep his eyes open. The post sex sleep was hitting him hard.

“Yes, it was,” Luna replied. She rolled over and looked at him. “Do you want to go on a date with me?”

The surprise question was almost enough to wake him back up.

“Yes, I would love to,” He smiled before the post orgasm sleep overtook him.

Welp, after so long a break, the story is out.
