Silence filled the bedroom as some time had passed, Rainbow Dash now lying on Rarity's bed with her forleg wrapped around the other mare cuddling her close while she had fallen asleep in the pegasus's warm embrace. Dash nuzzling the sleeping unicorn slightly as a small smile slowly formed on her lips, kissing Rarity's forehead lightly and causing her to stir as she started to awaken from her short nap. Her sapphire eyes blinking a couple of times as they got used to the still quite bright light of the afternoon sun coming in through the window and covering the bedroom in a gentle glow.

Rarity yawning slightly as she slowly sat up and sighed deeply, turning her head towards the other mare as she heard her speak up in a relaxed tone, "You sure do look quite exhausted Rares, I'm sorry I didn't mean to tire you out that much," Dash joked smirking to the unicorn, as she just raised her eyebrow a little before rolling her eyes in response to the pegasus's teasing.

"Well I didn't really get much sleep last night," she stated with a shrug of her shoulders, 'Actually I got no sleep at all,' she thought with a slight shake of her head as it was clear that she still felt worn out and could most likely do with having another nap at this point, however the unicorn getting distracted from herself as Dash caught her attention again a moment later.

"Yeah I didn't sleep too well either; too much on my mind I guess," the cyan mare chuckled slightly as a nervous expression formed on her face, glancing away from Rarity, while she widened her eyes a little, only now really realising that she maybe wasn't the only one of them that had been confused and asking herself questions about the situation they were both in all this time.

The two mares going silent as they both turned away from each other, there being a bit of awkward tension in the air at the moment, while it seemed like they were thinking to themselves about what they should say or do right now. However Rarity soon breaking the quiet as she let out another heavy sigh and looked back to Dash with a bit of a nervous expression still.

"So...where do we go from here then?"

She asked as it seemed like she was unsure about just what this all meant for their friendship, and whether everything that had happened over these past three days had caused it to change or perhaps even become something more. Rarity waiting for a response from the other mare, but it not looking like she was going to get one as Dash just continued to think to herself at the moment, with an uneasy expression still formed on her face, giving the unicorn the impression that she was also a little stuck on where this all left the two of them now.

"I mean...I do...love you Rainbow, I'm not denying that anymore, but..." she added, trailing off a little as she hoped to encourage the other mare to chime in and maybe suggest something, causing Dash to widen her eyes a bit, as she noticed that although she was still speaking in a low and nervous tone, the unicorn was becoming more confident in admitting her own feelings than she was just a little while eariler.

"I love you too Rarity," the pegasus replied, causing Rarity to widen her eyes and feel her heart still racing inside of her chest, only really now noticing that it hadn't stopped at all, "So...I don't think we can just go back to being friends after all this," Rainbow however added, as she truthfully really didn't want to just go back to being 'just friends', while Rarity just nodded slowly, turning her head away from Dash as she bit her bottom lip, feeling like she didn't want their friendship to change, but then she also didn't want to go back to the way things were like nothing had even happened between them both.

"I guess not..."

"We could try dating...if you want,"

Dash suggested before another awkward silence could fall on them, causing Rarity to look a bit taken aback for a moment, looking to the other mare and seeing that she had a more determined expression rather than a nervous one now, while she soon turned away again from Rainbow and lowered her tone to almost a whisper, trying to hide a slight blush that was beginning to spread across her cheeks.

"I would be alright with that...I guess,"

The pegasus seeing through her and thinking of encouraging Rarity to be more honest with herself and just say what she's really feeling at the moment, but decided to just stay silent and wait for now, giving the other mare some time to collect her thoughts and not pressure her to make a decision when she might not be ready to just yet. Rarity having moved away slightly from Dash as she was going through all this in her mind, wondering if things would be all that different for her and Rainbow if they did decide to 'try dating', and wondering if that was really what she wanted out of this relationship or not.

However it looking like it didn't take her very long to come to a decision, soon shaking her head as she knew she couldn't just spend ages thinking about all this and asking herself questions like she was doing before, if she wanted this relationship between her and Rainbow Dash to be something more, than she had to stop overthinking everything and just go with what her feelings were telling her right now.

"I mean...I would like to try dating, but...could we just keep it between us for now? I don't really want anypony finding out about it when we haven't fully grasped it ourselves just yet," she explained, turning back to Dash and trying her best to put on a confident expression, hoping that what she was saying actually made sense to the other mare, and luckily after a couple of moments Dash just let her lips form into a smile and soon nodded back to the unicorn in return.

"That's fine by me,"

She simply stated, as she held out her forleg, gesturing for Rarity to come back and sit closer to her again, the other mare feeling a warm sensation start to spread throughout her body as she just let herself relax against Dash. Letting the pegasus wrap her hoof back around and hold her close, feeling her lay a light kiss on her cheek, while she just buried her head into Rainbow's chest as her soft, cyan fur would brush against her face, nuzzling into her more and letting her mind just go blank as a blissful silence had soon fallen on them both once again.

However that not lasting for long it seemed as after a little while a couple of thoughts began to enter Rarity's mind, causing her to frown slightly, 'But then what about the bet? Will all those perverted things we've done to each other...will they stop now?' she wondered, questioning whether she wanted that to actually happen or not, 'Honestly...I...I just want things to stay this way...just for a little longer at least,' she sighed, before lifting her head and catching Rainbow's attention a few moments later.

"What does this mean for the bet though? I mean it's not over yet...right?"

Rarity asked with a bit of a nervous expression, as she felt uneasy when seeing that her question had caused the other mare to widen her eyes and look quite clearly surprised in response, staying silent for a little while as it seemed like she was thinking to herself for a few moments before she had her own question to ask the unicorn in return.

"Well no, I guess it's not over just yet, but...Rares...do you actually...like being my slave?"

Dash raised her eyebrow as she clearly wasn't expecting Rarity to still be going on about their bet and all that after they had both confessed to each other not too long ago, but it certainly seeming like the unicorn didn't want to just let it go for some reason. Rarity biting her bottom lip as she felt a slight blush starting to spread across and cover her cheeks, while she turned her head away from the cyan mare and lowered her tone to almost a whisper once again, causing Rainbow to lean closer to her, obviously wanting to hear more from Rarity now.

"Well I...I did say eariler that I do...actually like doing all those perverted things with you...and I believe it's true to say that you make me feel something I've never felt with any other pony before. The truth is...nopony has ever dominated me the way you do, and none of the stallions I've been with in the past have been able to get me to submit to them as easily as my body does to you Dash, and I guess...I do like being dominated by you, and I do want to see more of that side to you that I would never normally see. So...yes, I like...I love being your slave Rainbow," the unicorn explained still looking nervous and anxious at first, but as she continued on going into more detail she soon became more confident and now looked back to Rainbow Dash with a more serious expression, letting the cyan mare know that she meant every word she said, causing the pegasus to seem taken aback once again, not knowing what to say in reply for a while, however it not taking her too long to think of something luckily.

"I had no idea...I mean I could tell you enjoyed going all the way with me, but I...I didn't know that you felt like that. To be honest I do think your submissive side is really cute, and I would also like to see more of it..." Dash trailing off a little as she herself felt a bit nervous, hiding the fact that she also was beginning to blush as well right now, causing Rarity to widen her eyes and nod to herself a moment later, it seeming like she had decided on something.

"Than I'll commit to this and let you do whatever you want, you can do anything you like with me, I won't object or refuse, after all it's not like I would want to anyway. Even if it is shameful and humiliating I won't care, and if you want me to follow you around town, doing as you say all while wearing that collar that you brought for me...then so be it," she stated as her expression looked a lot more determined now, causing Rainbow to again go quiet for a few moments, as she couldn't quite believe the fashion pony was saying all this to her, but could clearly tell just how serious Rarity was about everything she was saying, and so soon just hesitated a little before asking another question to the unicorn in response.

"Rarity...do you really want to stay as my slave that badly?"

Rarity just nodding in reply, seeming very sure of herself "It's because it's you that I'm willing to do all this, Rainbow," she said, softening her expression, as Dash saw the deep blush covering her cheeks at the moment, while she let the cyan mare know that she was willing to give all of herself over to her, not because she felt she had to in any way, but more because she could then prove to Dash just how much she really loved her and wanted to discover more about herself as well as the pegasus while being together with her.

Dash's magenta eyes going wide as she thought about all this, taking into account just what Rarity was willing to do for her, unsure of what to do for a few moments, wondering if she should just go along with what the other mare was suggesting and let her fulfil the bet that they had originally made, or if maybe there was some other way for the unicorn to give all of her herself over to her, and soon realising that she wanted to do the same for Rarity, as an idea was now forming inside her mind and causing her to sigh with a small smile, while she looked back to Rarity with a more confident expression.

"Well...instead of having you embarrass yourself in front of all of Ponyville for me, I think I have a better idea," she replied with a simple wink to the other mare, causing Rarity to now look confused, tilting her head to one side as she was clearly wondering what Dash was talking about and obviously wanted to hear more, as the pegasus soon explained just what this 'idea' of her's was having Rarity lean closer to her while she listened carefully in return.

....

Rainbow Dash having left Rarity's boutique afterwards as she had gone to run some errands in town that she needed to, while letting the unicorn get back to her own tasks that they both knew she should be focusing on more at the moment, as they left each other alone for a few hours so that they could concentrate on themselves for a bit. The cyan pegasus soon returning back to her cloud home late in the evening as she sighed and felt like she was finally starting to really grasp all that had happened today between her and Rarity, feeling a little tried out as she slowly made her way to her bedroom.

However that seeming to change once she opened her bedroom door and entered to see Rarity lying sprawled out on her bed with her hind legs spread apart, already presenting herself to the other mare, while her diamond-studded, purple collar hung rather loosely around her neck and she looked to Rainbow with a deep blush covering her whole face at the moment.

"So you let yourself in I see," Dash smirked with a raised eyebrow, not seeming at all surprised by this however as she knew exactly what the unicorn was here for, and was more than happy to tend to her wants and needs. While Rarity just bit her bottom lip and glanced away from the cyan mare, before looking back to her with pleading eyes.

"Well you did give me a key after all, and...I'm afraid I just couldn't wait any longer,"

She spoke in a low voice, shrugging her shoulders slightly as she grinded her flank against the bed, making a gesture to her neather regions and causing Rainbow to glance down to see just how aroused she was right at this moment. Dash just letting a small chuckle leave her lips as she looked to Rarity's winking slit, before closing the bedroom door bedhind her and walking up to the awaiting unicorn.

"Well looks like my slave's quite the impatient one tonight, were you able to get all your dresses finished at least?" the pegasus asked as she climbed on to the bed, leaning over Rarity and already lying a light kiss on her forehead, while the other mare just took a deep breath, preparing herself for what was to come, nodding back to Rainbow in reply and gazing deep into her magenta eyes, in turn Dash staring into her sapphire ones.

"Yes, luckily I was finally able to focus and got them all completed, I even got the chance to get back to a couple of the client's I needed to talk to, as well as calling and catching up with Sassy Saddles, filling her in on the plans for our next meeting," Rarity explained guessing that it had been much easier for her to focus now because she no longer had anything troubling her mind and dominating her thoughts anymore, having nothing holding her back from doing the things she needed to get done, and at the same time wanting to finish her work rather quickly as she was looking forward to what she had planned with Rainbow Dash once the late evening had started to settle in.

"Well...it seems like my cute slave deserves a reward for all her hard work,"

Dash stated with a wink, her voice having a seducing tone to it as she leaned down and licked the other mare's ear, causing her to shiver and bite her bottom lip, already feeling the pegasus's soft feathers brushing over her entire body, while Rainbow moved one of her wings along practically every inch of Rarity's trembling form, knowing exactly what to do in order to 'flip her switch', and get her moaning and begging for more.

"Mmmm...Rainbow...I love you..."

She whispered out in-between her slight moans and heavy pants, as she rested a hoof against Dash's cheek, caressing her softly, while the cyan mare just smiled to her in return, as everytime she heard those three words leave Rarity's lips she could feel a warm sensation spreading throughout her chest.

"I love you too, Rares,"

She replied, before closing the tiny gap between them and locking their lips togeher in a deep kiss, causing Rarity to widen her eyes slightly, already feeling the cyan mare slipping her hot tongue inside of her mouth, starting to explore her walls and soon suck on the unicorn's own eager tongue. Rarity feeling her body completely submitting to Rainbow as it always did and just allowed herself to do so, her body continuing to tremble and melt as every place that Dash touched, licked, kissed, bit, or sucked on felt like it was all sending wild shockwaves of intense pleasure through her veins.

Dash soon crouching down between Rarity's hind legs, stroking her inner-thighs with both of her wings, causing the other mare to shake in response, while the pegasus just teased at the folds of Rarity's already soaked slit, hearing her moans begin to get louder and advancing more when feeling one of the unicorn's hoof rest against her head, licking slowly and often stopping to lightly suck on her clit, encouraging it to swell up and become stiff.

"Rainbow...Ahhh...don't just tease me like that...please..."

The blushing unicorn panted out between her low moans, pleading with slight tears in her eyes for the cyan mare to give her more pleasure and be rougher with her than what she currently was at the moment. Rainbow just glancing back to Rarity's begging expression and soon slowly slipped her tongue inside of the other mare's awaiting entrance, giving her the attention she was asking for and causing her to cry out louder, while she could feel the pegasus starting off slow, gently thrusting her tongue in and out, but increasing her speed and reaching further before long.

However Rarity still having an unsatisfied and pleading look in her eyes, causing Dash to guess that she wanted more, as she stopped what she was doing for a moment and licked her lips, tasting the bittersweetness of the other mare's juices, while she soon raised an eyebrow to Rarity, "Do you want me to be even rougher with you?" she questioned with a slight smirk, as the unicorn just bit her bottom lip and nodded back to Rainbow as her desire just kept raising, obviously wanting a release right now.

"Very well then,"

Dash simply shrugged her shoulders as she went back to plesauring the other mare with her skillful tongue, thrusting it deep inside her drenched marehood and soon causing her climax to start building up inside her lower abdomen. It not being long before Rainbow began to get rougher again, reaching her tongue as far as it would go and thrusting it deep into Rarity, knowing exactly where all her weak spots were as she stirred up the moaning unicorn more and more.

"Rainbow...AHHH! Please be rougher with me...make me scream out your name louder....Dash I'm...AHHHH!"

Rarity gritting her teeth and crying out loudly, feeling her climax building and building inside her core, knowing that if the cyan mare kept being this rough with her then it wouldn't be long before she would be so close to reaching her limit, already feeling like she was about to brust from all this incredible pleasure coursing throughout her body. Rainbow could just tell how close the unicorn was getting from the way her walls would tighten and clamp down on her tongue, begging for her to give her a release that she clearly needed at the moment.

However just as Rarity was coming close to being throw over the very edge, she felt the pressure inside her stomach start to subsize and causing her to widen her eyes, looking down to Rainbow and realising that the cyan mare had gone back to just teasing at her folds, still sucking on her swollen clit every few moments though. Dash just opening her eyes slightly, before winking to the uniorn and being ever so tender with her licks, making Rarity believe that she was just torturing her now and wanting her to beg her for a release it seemed.

"No Rainbow...please...don't stop now, not when I'm this close...please Mistress Rainbow...just please let me come!"
The unicorn raising her voice as she cried out loudly, and looked to Dash with tears in her eyes, begging for her to stop teasing her and just give her the release that she needed.

Luckily Rainbow deciding to be generous tonight, hearing Rarity call her 'Mistress' seeming to be enough for her as she thrusted her tongue deeply inside of the other mare's entrance, doubling her efforts as soon she got a rhythm going and it not taking long at all for Rarity's climax to build back up like it was before, feeling pressure quickly filling her lower abdomen and once Dash could tell that she was getting close again, this time she started being even rougher with her thrusts causing the unicorn to be pushed to her limit and not being able to hold back any longer.

Her hips buckling and her head being thrown back into Rainbow's pillow, as she could feel waves and waves of bliss overwhelming her and causing her whole body to shake uncontrollably. Dash making Rarity ride out her breathtaking orgasm as she happily lapped up all of her overflowing juices, not letting a single drop miss her lips, before she soon swallowed it all and just licked her lips, sitting up and smiling down to the other mare as she watched her slowly starting to recover and come down from her high.

"That...was mean," she panted out as it was clear that she was still trying to get her breathing back to normal, pouting to Dash and lifting her head slightly while she could still feel her heart pounding inside her chest, her expression causing the cyan mare to just smile nervously back to her in reply.

"Sorry, you just looked so cute that I couldn't help wanting to prolong the moment, and see more of your adorable reactions," the pegasus stated, causing the other mare to just roll her eyes with a slight smile, before she sighed heavily and seemed like she was thinking for a moment, a frown forming on her lips while Dash looked back to her with a curious expression, wondering what was on her mind right now.

However finding that she wouldn't have to wonder for very long at all, as she soon heard the unicorn speak up in quite the low and nervous voice, "This...won't be the last time that we do this...right Rainbow?" she asked, turning her head away and feeling a bit uneasy about how Dash would respond to her question as the cyan mare widened her eyes slightly, before she just softened her expression and shook her head.

"Of course not Rares, this bet can last much longer than just three days, and you can come over to be my cute slave anytime you like," she simply smiled with a nod, causing Rarity to widen her eyes and look really relieved before she soon just chuckled slightly and looked back to Rainbow with a raised eyebrow.

"Well I think you and I both know that this has become much more than just part of that bet now, after all..." the unicorn pausing for a moment as she let a softened smile form on her lips and gazed deeply into the cyan mare's magenta eyes, "I'm already all yours Rainbow Dash," she added, causing Dash to seem a little taken aback at first, however soon just smiling back to Rarity in return.

"And I'm all yours, Rares,"

She replied as she leaned over the other mare again and let her rest a hoof against her cheek, before she soon pressed her lips to Rarity's and kissed her deeply, while the unicorn just melted and let Dash pin her back down on to the bed, feeling the cyan mare starting to slip her tongue in and allowing her do so, as they moaned pleasantly and held each other in a warm, loving embrace, both of them clearly being glad to know that this was only the beginning to their new and exciting relationship that only they would know about.
