Today had been a busy and tiring day that just seemed to have dragged on forever. The talented seamstress Rarity, had spent all day working on and finishing off all the new desgins that would be sold at her boutique in Canterlot, she may have been cutting it a bit too close, but by the end of the afternoon, once she asked her friends if they could chip in to help her a little, she was able to get all the outfits finished and packed into boxes, ready to be shipped off to 'Canterlot Carousel'.

And so now, she sighed happily, feeling exhausted, but glad that everything was now done, looking to her friends as they were all helping to pile the boxes up together so that they would be ready for when the mail pony came for them tomorrow. Rarity couldn't be more greatful for having close friends that would all help her out whenever she needed it, she didn't know if she would have been able to finish it all on time without them.

"Well that's the last box," Twilight stated as she stepped back, looking over the neat pile of boxes, and nodded her head in satifaction, before she turned away from the pyramid of carboard boxes, and walked over to stand beside Rarity, while the unicorn smiled to her.

"Phew glad that's all done," Applejack sighed with relief, as she came and stood beside Rarity, while she fanned herself with her hat, feeling a little warm, and worn out, just like most of the group did right now.

"Umm Pinkie Pie, what are you doing?" Fluttershy asked as she looked over to the pink earth pony, causing for Twilight, Rarity and Applejack to do the same.

"What's it look like, we're building a tower of course," Pinkie answered as she glanced to Fluttershy, before she looked back to the high tower of spare boxes her and Rainbow Dash had been building,

"Put one more box on Dashie,"

"Pinkie if she puts on one more box, it's going to fall," Starlight stated, as she looked anxiously at the way the tall pillar of brown boxes was swaying slightly, looking like it could topple over at any moment.

"Aww come on Starlight just one more box won't cause it to fall," Rainbow stated as she happily lifted up one more box in her hooves, and flew up to the top of the tower, ready to balance the one she was holding on the peck of the wobbling pillar.

"Then try it by all means," Starlight simply said as she shook her head slightly, and turned away from the cyan pegasus, knowing that she would regret going along with this idea of Pinkie's once all those boxes came crashing down.

"Gladly," Rainbow smirked as she gently placed the box she was holding on to the top of the tower, keeping a tight hold of it at first, before she let go of it slowly, smiling when all the tower did was sway a little more. Dash was going to proudly point out that she had been right, but just before she could the tall, wobbling stack of boxes began to tip, before it quickly collapsed.

"Uh oh.TIMBER!" Pinkie shouted loudly, as she ducked, while everypony else gasped, before they all went to try and catch the boxes that would soon be falling to the floor.

However luckily there was nothing to worry about, as Starlight caught all of the falling boxes in her magic before they came close to the ground, holding them all as she smiled to Rainbow Dash with a raised eyebrow, while the others all sighed in relief.

"Told you it would fall," the poweful unicorn stated, before she gently lay all the boxes down on the floor, piling them up into a nice neat pile just like the other ones near to the door of the boutique.

"Yeah, yeah, I got it," Rainbow replied as she looked back to Starlight with an annoyed expression, mumbling something under her breath, while she flew to stand beside Twilight, and kept her head turned away from the lylic unicorn. Stralight just smirked to the cyan pegasus, while she rolled her eyes slightly in return, and turned away from Dash.

"That was fun, let's build another one!" Pinike jumped up excitedly, her voice sounding full of joy, while the others couldn't understand how the party pony still had so much energy in her, when she had also been helping out all day, having never really stopped for a break until now.

"Umm Pinkie, it's getting late now, don't you think we should all be heading home?" Fluttershy suggested kindly to Pinkie, knowing that building another tower could only end up in another close call or a potential mess that would take a while to clean up.

Pinike's happy expression seemed to turn into a frown slightly as she looked to Fluttershy, "But when the tower falls down you have to build it back up again," she stated, like it was an obvious rule that the yellow pegasus should know about.

"Hey we can build another one tomorrow," Starlight suggested as she came and stood beside Pinkie.

"Really?" Pinkie asked as she looked to Starlight with hopefilled eyes.

Starlight nodded in reply with a kind smile, "Yep, and maybe if we build it outside, we can build it even higher, because it won't matter if it falls down or anything then," she explained, hoping that this would make the pony agree to leaving and them all going back to their own homes for the night.

Pinkie cheered with delight as a bright smile spread across her face, and she was back to being her normal happy-go-lucky self again, while the others just all smiled to her with slight chuckles, thinking about how the pink earth pony really did seem like a big foal sometimes. Twilight smiled proudly as she was glad to see how much her friends had connected with her student over this short amount time that she had been part of their little group.

"Right I think it's safe to say, that we all should be leaving now, after all I can't leave Spike looking after the castle on his own all night," Twilight stated as everypony else agreed that it was time to head off back to their homes for the night, leaving Rarity to get some much needed rest, so that she could be up early for tomorrow.

"Thank you all for helping me out today, I don't think I could have got everything finished without you all," Rarity stated as she smiled to all her friends, feeling lucky to have them around whenever she may need them to lend her a helping hoof.

"You're welcome Rarity," Twilight nodded with a smile.

"Anytime Sugarcube," Applejack said as she put her hat back on top of her head, and smiled to Rarity as well.

"Yeah it was actually quite fun," Rainbow Dash added, while Fluttershy, Pinkie and Starlight all nodded in agreement, before they all started to head for the door together.

Rarity was about to say goodbye to them all, when she suddenly thought about something, looking down to the floor for a moment, before she stopped the others in their tracks and caught their attention, as they all turned round to look at her.

"Ah wait, Rainbow Dash, could you stay for a little longer? I need to ask you about something," Rarity asked as she smiled to Dash slightly, giving her a look that only the cyan pegasus knew the meaning behind, as she looked to the unicorn for a moment, before she smiled in return.

"Sure," Rainbow replied without a second thought.

"What do you need to ask her about?" Pinkie Pie asked, as she and the others were wondering why Rarity had asked for just Rainbow to stay behind.

"It's nothing to be concerned about, something has just been bothering me lately, and I would like to talk to her about it, that's all," Rarity explained, as she looked to Pinkie with a smile, but glanced back to Rainbow a second later.

And with hearing that the group all said their 'Goobyes/Goodnights' to Rarity and Rainbow Dash, as they all left out the door, and started going their separate ways,

"What do you think that was all about?" Twilight asked Starlight as they had started making their way back to the castle togther.

"What do you mean?" Starlight asked, looking a bit unsure as to what Twilight was talking about.

"Why do you think Rarity asked just Rainbow Dash to stay with her for a little longer?"

"How should I know? it's probably just something about reminding Rainbow to stop flying through her windows or whatever," Starlight stated as she wondered why the other mare was so interested in the topic of Rarity simply talking to Rainbow Dash about something or other.

"Yeah, I guess you're right," Twilight nodded, before she stopped walking and looked back to Rarity's home for a minute, as she seemed a little supicious about two of her friends.

"Twilight?" Starlight called back to the Princess, as she realized that she had stopped for some reason.

"Yeah, sorry I'm coming now," Twilight replied as she gave the boutique one last look, glancing to the window, seeing that all the curtains were closed, but could tell that the lights were still on in some of the rooms. Twilight turned back as she picked up speed to catch up with Starlight, still feeling a little spectacle about this situation, but decided to not let it play on her mind too much, after all it's not like it would be anything to be worried about right?

... ...

Late evening was now beginning to set in, as Celestia's sun had not long gone from the sky, and most of the residents of Ponyville had gone back to their nice warm homes, with only a short amount left outside in the open still.

Rarity was laying on her back, resting on her bed, while her breath came out in heavy, spaced out pants, biting her bottom lip as she sighed slightly. Rainbow Dash stood over her, looking to her with a smile, as she leaned down and licked her sensitive ear, causing the unicorn to shiver and moan a little.

This was how most of these nights went for the two, Rarity would ask Rainbow to stay over, and Rainbow would happily agree to it without any hesitation in her voice, then from there the two mares would engage in passionate love making, until they eventually got tired and decided to call it a night, cuddling up close to each other, before falling asleep together.

This hadn't been going on for very long, maybe only a little over a month or so give or take. They didn't spend every night together, but mostly they would end up doing these things once, or twice, or sometimes even three times a week, depending on how busy the two of them would have been throughout the day. Only this time Rarity had been busy pretty much all the time, so they hadn't gotten the chance to spend any time alone together until tonight.

"Rainbow...don't go too far tonight, I'm still a little tired from today," Rarity spoke inbetween slight pants, while her body shook a little as a reaction to the pegasus attacking her ear.

"If you're tired then why did you ask me to stay round?" Rainbow asked, as she gave Rarity's ear a long, slow lick, causing her to cry out in reply. By now Dash had learnt what Rarity wanted whenever she asked her to stay round at her's, after all she would always give her that look of hidden desire, that nopony else saw, only Rainbow Dash knew what it meant, it meant that she most certainly wouldn't be going back to her own home that night.

Rarity didn't answer right away, instead she just lay panting slightly, and looked away from the pegasus, a deep blush covering her cheeks, while Dash just smiled to her, waiting to hear her answer, always chuckling a little inside when she saw that embarrassed and cute side to the unicon, which only she knew about.

"Well...it's just that we hadn't done it in a while," Rarity nervously spoke as her voice came out in a shy whisper for a moment, not wanting to admit that she been missing these nights, and had constanly been lusting after the cyan pegasus for a good while now.

"Ah so you've been graving my touch, right?" Rainbow smirked as she left Rarity's sensitive ears alone, and instead moved on to her horn now, kissing its tip lightly, while the unicorn's slight moans were like music to her ears.

"Yeah right, in your dreams maybe," Rarity shot back as she smiled, and breathed through the intense pleasure she was feeling right now,

'My ears are still very sensitive it would seem, but at least I can bare with her playing with my horn better now. When she first did this to me I found it to be a bit too much for me to handle at the time, however now I find that her licks and light kisses against my horn are very stimulating. I think Rainbow just likes doing it to make me get off faster to be honest,' Rarity thought as she gritted her teeth a little, when she felt her dominating lover licking the base of her horn, before the pegasus took the whole horn into her mouth and sucked on it lightly, causing Rarity to cry out quite loudly, as she shut her eyes tight, and felt all her muscles tensing up a little.

'Well I'm fine, until she decides to do that,' Rarity sighed deeply, opening her eyes again, while she tried to calm her breathing down a little, her heart beating wildly in her chest, as Rainbow sucked down harder on her horn, before she trailed her tongue up to the very tip, giving it one final tender kiss, then leaving the horn coated with her warm saliva.

"Hey Rares,"

"Hmm?" Rarity whimpered slightly as she looked to her lover, and could guess where things were going to be going from here, just by seeing that seductive look that Rainbow had in her bright magenta eyes right now.

Dash smirked as she moved one of her hind legs so that her hoof was positioned between Rarity thighs, nudging the unicorn's legs at first so that she would realize just where the pegasus was touching her right now. Rarity gasped in return as she almost instandly knew just where Rainbow's hind hoof was touching her, trembling stlightly when she felt the limb caressing her fur, and noticed just how close the appendage was to her soaked entrance.

She didn't refuse or tell Dash to 'wait', instead she just lay there, her body shaking slightly, while she clenched her teeth together tightly, biting back a couple of loud moans, gasping again as she felt Rainbow's hoof move forward slightly, and start to gently rub against her crotch, teasing her lover with these very light touches.

"You sure are drenched, how long have you been like this?" Rainbow asked as she made her momovents almost as slow as they could be, making sure to thoroughly stir up the panting mare laying below her. Rarity moaned and squirmed in reply, her sapphire eyes welling up with tears, while it never seemed to surprise her anymore at how easily Rainbow Dash could make her feel like screaming, and being close to begging the pegasus to just make her cum already.

"Please Rainbow...quit teasing me..." Rarity pleaded, as she gazed up to Dash with longing eyes, her cheeks turning to a deep crimson red, while she could feel the pegasus's cyan fur brushing ever so softely against her moist folds, causing it to be much more noticeable of just how aroused she really was down there.

"Okay, I won't make you beg for it this time," Rainbow stated as she leaned down, and pecked Rarity lightly on her cheek, knowing that she was tired from today, and probably didn't want to beg for the release that she so desperately needed, and no doubt definitely deserved.

And so within a few more seconds Rainbow positioned herself just below Rarity's lower abdomen, and smiled as she never got tired of seeing the unicorn's soaked sex twitching in anticipation, while it overflowed with her juices, begging for the pegasus's attention. Dash didn't waste anytime it seemed as she quickly started getting to work, licking, kissing, and sucking on her lover's vulva, being sure to give her already swollen clit plenty of her attention as well.

'This feels good...way too good,' Rarity thought as her loud moans soon turned into even louder screams, her mind now gone completely blank and her heart pounding in her chest, she had already been stirred up enough, and as that very familiar sesation of an excessive amount of pressure building up in her stomach, she knew she was close.

Rainbow continued, not giving Rarity a single second of a break, as she started to thrust her tongue deeply inside of the unicorn, wanting to push her over the edge rather quickly. With her climax quickly approaching, Rarity couldn't hold back her loud voice, the room fillled with her screams, while she threw her head back in a feeling of absolute ecstasy, it was almost like she was about to brust.

"OH RAINBOW DASH! AAAHHHHHH!"

Rarity moaned out loudly, before she screamed out a loud cry of release, shuting her eyes tight, as tears of sheer bliss streamed down her cheeks, arching her back up off of her bed, while she felt wave after wave of extreme pleasure rippling through her entire body, causing her to shake violently all over, and buck her hips up, rolling them into Dash's fast and deep thrusts.

Rainbow happily lapped up all of Rarity's sweet juices, swallowing all that she could, while she made her lover ride out her overwhelming orgasm, not stopping until she saw the unicorn collapse on her bed, gasping for air, as her lungs begged for oxygen. Rainbow smiled as she stood over Rarity again, watching her pant heavily, while she kissed her tears away, and waited for her to come down from her high.

Finally after a good few minutes, Rarity was able to breathe normally again, sighing deeply as she lay her head back on her pillow and relaxed, basking in her afterglow, while she gazed up to Rainbow Dash with a smile.

"That was quick," Rainbow commented with a wink as she kissed Rarity's forehead lightly.

"Well what do you expect when you're that aggressive, not to mention the fact that you kept going for my weak spot," Rarity glared to the pegasus standing above her, blushing deeply, while she nervously turned away from Dash, however was brought back to face her as Rainbow kissed her deeply.

'I don't mind letting Rainbow see that shy side of me, she's the only pony that knows about it after all, and although I may not like it when she calls me cute or teases me, I sure do love it when she takes complete control, and dominates me like nopony has before,' Rarity thought as she melted into the tender kiss, giving out a pleasant moan, before their lips parted.

"Hey Rainbow?"

"Yeah?"

"When are we going to tell the others about us?" Rarity asked as she remembered how Pinkie Pie had asked her eariler what she wanted to talk to Rainbow Dash about, and she wasn't exactly being truthful when she answered her.

"I thought we agreed that it would just be our secret," Rainbow raised an eyebrow as she looked a little confused as to why the other mare was worrying about this now.

"I know, it's just...I hate having to lie to them," Rarity sighed slightly, as she looked to her bedsheets nervously.

"We're not lying to them, we're just not telling them the whole story," Rainbow smiled, causing Rarity to give her a slightly annoyed look.

"Besides what would we even tell them? It's not like we're a couple or anything," Rainbow pointed out as it was true that neither one of them wanted to say that they were dating, since most of their relationship was mainly all physical with hardly any deep feelings behind it, after all the only reason why they carried on this was to give each other a relief from their stress, fulfiling their hidden desires, while not having to worry about showing who they really were.

"No, but we are lovers," Rarity said as she knew there wasn't really anything between the two, besides these nights they had together, whether that was the way it would always be, she had no idea.

"The way we're going about it, it seems more like we're just 'Sex Buddies' really," Rainbow smirked as she didn't think the word 'love' had much to do with how they felt about each other.

"Rainbow," Rarity glared to the pegasus again slightly, while she just smiled back to her.

"But what if they don't approve of us? Or what about if they get mad at us for keeping them in the dark about what has been going on between was?" Rainbow asked, basically just repeating what Rarity had been worried about on the night that they started this...'unusual arrangement'.

"I guess you have a point there," Rarity agreed as she was still worried about their friends getting mad at them for not telling them about what was going on.

"Besides, I kinda like the idea of this just staying as our 'dirty little secret'," Rainbow smiled as she leaned down to Rarity and gave her ear a quick lick, causing the other mare to shiver and moan a little in return.

Rarity blushed deeply as she couldn't hide the fact that she kind of wanted things to stay the way they were now as well, wrapping her forelegs around Rainbow's neck, and holding her close, loving how gentle the noramlly very forceful pegasus could be at times.

"I would just like for us to be the ones to tell them, before they figure it out for themsevles, say by catching us in the act or something like that," Rarity explained wondering if any of their friends had become suspicious about them yet, they had been very carefully, but there was always that possibility.

Rainbow Dash nodded as she agreed that it would be better to tell their friends about what was going on, rather them finding out some other way, "Fine," she stated with a slight sigh, "If it will stop you worrying about it, we'll tell them the truth,"

"Really?" Rarity asked, glad that Rainbow was agreeing to this, she knew that there would no doubt be some troubles once they did come clean about everything, but they didn't have to tell them right away. Rainbow Dash just nodded with a smile, before Rarity brought her into a tight hug, smiling as the pegasus hugged her back,

"Thank you Rainbow,"

"No problem, Rares," Rainbow chuckled slightly as she felt Rarity nuzzling into her neck, wondering how their friends would react when they found out about this awfully cute side to the normally very prissy unicorn.

The two stayed hugging each other like that for a while, enjoying the comforting feeling of the other's warmth in the loving embrace they shared. Rarity pulled out of the embrace slightly, as she brought Rainbow into a deep kiss for a moment, biting her bottom lip once their lips had parted, obviously she wasn't as tired as she first thought she was.

"But you know, we don't have to tell them straight away," Rarity pointed out as she gave Dash a very alluring look, smiling when Rainbow seemed to catch on to the message she was hinting at her.

"Well in that case, do you want to go for another round, before we call it a night?" Rainbow asked as she smiled back to Rarity, and leaned down to her, laying a few light kisses on her neck, while Rarity tilted her head back to give her lover more of an easy access.

"Sure, but go slow this time okay?" Rarity asked as she didn't want Rainbow to make her cum as fast as she had a little while ago.

"As you wish," Rainbow agreed, before she started to attack her lover's senstive ears again, causing her to moan and tremble in return.

'We'll tell them about us eventually, but for now it can just stay between Rainbow Dash and me, after all there's nothing wrong with keeping them in the dark about it for a little longer, right?'
