Rarity walks into the cold and dark room, shivering from both the chill and that deep rooted fear of the dark she knew was irrational, at least with the current location and present company. Maybe. Twilight did have her moments after all... . Rarity stops only a few paces into the room, unable to see if she would step on or run into anything. The light coming from the hall behind her did not reach as far as it should have and she suspected a dampening spell of some sort was in place. Just as she was about to say something the lights click on above. Bright blinding lights. Letting out a slight gasp of pain and covering her eyes with one leg Rarity tilts her face down to help. She jumps a bit when the door closes with a loud clunk sound and turns around fully; rapidly blinking her eyes to clear away the spots.
And when the spots clear she sees another unicorn mare, same shape, size and coloration as her dear friend Twilight Sparkle. But this pony was not Twilight Sparkle.

This new pony had a calm confidence of one who knew the sun revolved around her and not the planet she just happened to be on at the moment. Her back was straight, head held high and she looked down her muzzle a little. Not so much in a condescending manner, more like the gaze of a mare who was used to getting what she wanted. Despite the fact that Rarity knew the two of them were about the same height she couldn't help but think that this not-Twilight was a little taller than she was. After a moment's thought she realized that particular illusion was probably helped by the fact she had subconsciously tucked her body down into a submissive pose and even though she now knew about it she couldn't force herself to relax and stand straight.

Not-Twilight steps closer, slowly, smoothly as if she had all the time in the world. Her body language showed control and dominance but not hostility. She stops half a pace from Rarity, reaching down and placing a hoof under Rarity's chin, rubbing gently and lifting up just a little to help make eye contact. The eyes were still Twilight's, soft, caring and full of friendship. Seeing that look in those eyes helped ease Rarity's fears some and she relaxes a bit.
Twilight gives a light inviting smile but it didn't seem quite right to Rarity. When Twilight spoke her voice was smoother than silk and sweeter than sugar, melodic and very very sexy. Hearing it sent a little trill down Rarity's spine, causing her to shiver in something other than fear or cold.

"Such a beautiful mare. Tell me, what is your name?" Twilight was wanting to get right into things now that they were down here it seems, no more stalling. Rarity had to make a choice, either to be herself or construct another persona. She wasn't feeling very much like herself right now so another name might be best.

Now she just needed a name.

Her eyes dart left and right but from this angle she could only see the door, the blank wall around it and Twilight's face right in front of her as well as some of Twilight's body and the edge of her star-burst cutie-mark. Rarity's eyes linger on what she could see of said cutie-mark and it makes her think of her own. Of three blue gems.

"Sapp-" She coughs, her eyes looking down to the floor. "Sapphire Shine." Twilight nods, gently sliding her hoof up along the underside of Rarity's muzzle until it fell away.

"A lovely name for a lovely mare. You may call me Mistress Sunrise, or just plain mistress. Do you understand Sapphire?" Rarity gives another light shiver. Twilight's voice wasn't scary and didn’t have any tint of cruelty to it but the shear control in the words and the tone used made her body tremble. And not in a wholly bad way.
They had only just started and it was already rather intense for the white unicorn.

Rarity nods her head at the question, still unable to force herself to look up. Some primal part in the back of her mind telling her that making herself as small and as quiet as she could be was the better option at the moment.
Twilight makes a slight tut sound and uses her magic to gently, but forcefully, lift Rarity's chin back up. Rarity's eyes widened; you just didn’t use magic on another pony without their permission! That was one of the first things a young unicorn learned.
She makes eye contact with Twilight again and sees… disappointment in them. It makes her flick her ears back and divert her eyes again. "When I ask you a question Sapphire I expect a verbal response. Is that understood?" The tone was shifted ever so slightly, firmer, more control and less honey. Some part of Rarity found it very interesting how much Twilight could convey by minor vocal adjustments. The purple mare was quite the actor. A larger part of Rarity just felt it best to not overthink the matter and do as she was told.

"Y-yes mistress." The 'm' word came easily to Rarity, rolling out without a second thought and did not leave the bitter taste she had expected. Twilight tilts her head some, magic rippling along Rarity's chin to feel like blunted claws digging into the skin, just enough to be felt but not enough to hurt. It was actually rather nice.

"'Yes' what Sapphire?"

"Yes I understand. Mistress." The second time was a bit harder, now that she thought about the word, remembering to use it and forcing herself to do so. Twilight did not seem to have a problem with the delivery though and cuts her magic, Rarity's chin dropping some. She catches her head, swallowing and looks down again.

"Good. Come Sapphire, it is time for you to see your new home." Twilight walks around Rarity and the other unicorn straightens her shaky legs as much as she could and turns around to follow. The room was not quite what she expected, but then again she was not really sure what she had expected in the first place.

The wall behind her now was only about one and a half pony lengths wide, the door in the center. The two walls on either side swept out at perhaps a forty-five degree angle, making the room a flat tipped triangular shape. The room was so large that the back wall was far enough away to be a little hazy and indistinct, just enough to not make out the details of the blurred objects there.
The entire left wall as far as Rarity could see was taken up by cabinets, sets of shelves and other such containers attached to floor or wall, all a mix of various sizes and shapes. The right wall was mostly bare, some chains here and there, but placed at even intervals a little off from the wall were various objects.
Rarity had no idea what some of them could be used for. There were too many things to list but the first thing that caught her eye was some sort of large X.

It was made of smooth dark brown lacquered wood and looked like it could be spun and turned in various ways on the two posts that held it aloft. Each branch of the X had a leather cuff and after a moment's thought Rarity realizes what it was for and felt another shiver run along her spine. A shiver of fear that she may be strapped to it tonight and, she had to admit to herself, a bit of excitement at the idea as well.
Of all that she saw Rarity could only guess as to their true nature, but some, like the X, were obvious in their uses. Especially the chains the hung from the ceiling over some of the… furniture. For not wanting to use another word for it all. Speaking of chains, more of them hung in pairs in the center area of the room, along with short chains on the floor or empty eye bolts.
When she sees the bolts Rarity thinks back to the story that got her interested in this mess in the first place and looked about for any sort of bar. Not seeing one right away she could only assume that it was located in one of the many hidey-holes along the left wall. Twilight just walked slowly towards the center of the room, Rarity following along absentmindedly as she looked around.
As they moved further into the room the back came into focus and Rarity could see that it had a tiled floor instead of the slightly rough (so hooves wouldn't slip) stone like the rest of the room. There were faucets and chains along the walls and ceiling as well as eye bolts and drains in floor.
It was a shower area where the fun didn't have to stop.
Once in the dead middle of the room, which just so happened to be under a dangling set of chains complete with manacles and three sturdy eye bolts in the floor, Twilight stops and turns back to look at Rarity.

"This is only the play room of course, but you can expect to be spending much of your time down here lovely Sapphire." The smile Twilight gave her made Rarity shiver again. It promised many things that smile.
Twilight looks to one of the manacles, inspecting it with her magic while she talks. "Tell me my dear Sapphire, do you have any experience in such activities this room promises?"

"No mi-mistress, I-I have never done anything… like this." Third time was a stutter, she was over thinking it again. As for thinking, the less Rarity had to lie about the easier it would be to keep to the character. She expected that was part of Twilight's plan, keep asking her questions and expecting answers right away so she didn't try to over think them.

"I do so enjoy teaching new things. Much of it will be scary Sapphire. Some of it will be painful even, but most of it will be quite enjoyable if you allow yourself to find it as such. Have you ever been intimate with a stallion?" The abruptness of the question made Rarity pause and blink.
She, Rarity, had indeed 'been' with a stallion. The question she found herself asking, well, herself, was would Sapphire Shine have 'been' with a stallion? More importantly, how would she respond to a question put like that? What kind of mare was Sapphire?

"I, I do not think that is any of your business." She gives a light pause, just long enough that it was known to be deliberate but not long enough to make it seem like she wasn't about to say more. "Mistress." Rarity straightens her back just a little, looking up about halfway, still keeping her posture submissive, just not as much as before. Twilight gives a half smile, titling her head to the side some.

"'You do not think'? Yes, that is correct slave you do not think." The 's' word made Rarity swallow and look down again. She knew it was all part of the game and she had agreed to it but being called that word struck a nerve in her. It hurt a little, to be called that. To be called the equivalent of a thing, of less than a pony. But, even though Twilight had said it in a stern tone of voice there was no malice behind it. "I will ask again Sapphire, and I expect a real answer this time. Have you ever been intimate with a stallion?" Rarity swallows, but straightens her back again and looks up fully this time, keeping her muzzle shut and not saying a word.

Twilight makes that tut sound from before and gives a light shake of her head. She turns to face Rarity's right, rolling her neck out in a slow motion with her eyes closed, as if debating what to do. She opens her right eye a little less than halfway and Rarity doesn't get any more warning than that before she finds herself wrapped in a purple aura, lifted up into the air and pulled closer to the other unicorn.
She was not lifted that high, perhaps an inch off the ground, nor was she pulled very far but it was enough to move her right under the chains hanging from the ceiling. Once there her back legs are set back on the floor but not her front legs. The purple aura moves to cover the chains as well as her and the former lower some, the manacles popping open without a sound.
Rarity tries to pull away, to fight against the magic, but it is too strong for her and she feels the cold metal close around her legs with a click, right above her pastern. They felt uncomfortably tight for a moment before the pressure lessened to being only mildly annoying. Twilight's magical aura drops off of Rarity's body, causing the white unicorn to shift her weight, adjusting her back legs so she wasn't pulling on her front legs as much. They were not being pulled above her head, instead when she settled her stance into something close to normal her fore-hooves were just level with the bottom of her chin.
She had not thought to use her own magic to counter the moving, because it happened so fast and was so unexpected, but now that she thought about it Rarity looks to the manacles and tries to focus her magic on opening them. She could fell the magic gather at the base of her horn but it didn't move any further, something blocking it. Crossing her eyes and looking up she could see her light blue aura being blocked by a light purple one. She then jerks her eyes back to Twilight, seeing that her horn was still glowing and she was now looking directly at Rarity, a light smile on her lips.

"M-magic suppression?" Rarity was not actually surprised Twilight could do that, but if she remembered correctly it was a rare ability in the time they were pretending to be in. Not to say it was all that common now-a-days though.

"Humm, yes. It is useful in my line of work. Would you prefer I get some spell-thread instead?"

"NO! N-no, please mistress." Being a seamstress Rarity was quite knowledgeable in fabrics and threads of all types. 'Spell-thread' as it was commonly known was actually properly called spellbinding-thread. It was spun from the silk of the arcanus arachnida, or 'mage spider'. The mage spider both passively and actively ate magic and its silk sapped the energy of its prey. Spinning said silk into thread and adding a bit of normal silk the resulting product would, when wrapped around a pony or other creature, sap their magic from them. Unicorns couldn't perform even basic telekinesis, pegasi would be unable to fly and earth ponies would find themselves as weak as a new born. It was said to be quite uncomfortable, an itch just short of actively painful and tended to cause rashes wherever it was placed that took days to clear up and totally ruined ones coat!
Twilight smiles again, and looks to the side, extending her magic out towards the cabinets, keeping Rarity's own magic locked down while she pulls something from storage. Rarity tries to turn to see what it is but it zips over to Twilight's side and moves behind her head before she can get a good look at it.

"Since you asked nicely Sapphire we will just stick with the binding aura then. Now, since you would not answer my previous question perhaps you will answer this one. Do you know what this is?" The object she had just retrieved moves out to float beside her head. It was a simple enough leather crop, about an arm length long with a unicorn's hoof sized flare at one end. Rarity tracks it with her eyes, swallowing again and licking her lips, her mouth suddenly having gone dry.

"A-a crop."

"Correct. A riding crop. Do you know what it is used for Sapphire?"

"To... encourage a pony to... move faster." She couldn't take her eyes off the crop. It could be used in many ways and was her first real sign of what Twilight had in mind for the night. She wasn't panicking, but she could feel her heart starting to beat faster and the room seemed to be getting a little brighter, her pupils dilating. She could also feel her tail flicking every so often against her will, and she had to make a conscious effort to keep it from doing so.

"Good enough. You do not really have the frame to be a riding pony Sapphire, most unicorns don't after all. However, the crop, as you say, can be used to 'encourage' a pony to do something. In this case I am going to use it to encourage you to answer my questions." Rarity swallowed, again, and watched as the crop flicked through the air. Twilight was deft and graceful with the tool, rolling it in simple loops and arcs. Rarity is just about to say something when it darts past her vision and smacks against her right thigh, below her cutie-mark. It stung for a few moments then passed into a slight warmth.
Rarity hissed in pain at the hit, and flicked her ears and tail at the burn. Before she could really respond though there was another sting on her left side, in the same spot as her right. The crop floats up in front of her face before dipping down under her muzzle and pushing up. Reinforced with magic the leather didn't yield and the white unicorn found herself looking back at Twilight, whom had moved closer. Very close. Rarity was almost nose to nose with her now.

They lock eyes and Rarity could swear there was an unspoken conversation between the two of them, a connection that went beyond words if you will. If words had to be placed to it it would simply be; Are you fine? With a response of Yes, please continue.
Twilight gives an ever so slight nod and slides the crop down Rarity's neck before pulling it away and delivering two sharp hits along her right thigh, each just slightly below and overlapping the one before it, including the very first hit of the night, and quickly doing the same on the left. In the end Rarity's upper thighs had a pleasant burn to them and she couldn't stop her tail from giving minor twitches back and forth. Twilight steps back, retuning the crop next to her head as she walks around Rarity. Rarity tried to turn her head to keep Twilight in sight but could only do so much with her forelegs locked the way they were. Even with her back legs free she felt it would be best if she didn't move from this spot at the moment.

"Two hits for each question without a proper answer and two more for back talk. Now, I will ask you again Sapphire, and now you know the price for not answering me; have you ever been intimate with a stallion?" Rarity opened her mouth to respond but then closed it, looking back in front of her and away from Twilight. The silence stretches for a moment before being broken by the smack of leather on fur and flesh. This hit landed above her left mark, and was slightly stronger than the others but the thicker flesh blunted the blow so it was only slightly more painful. A duplicate hit on the right was expected but still unprepared for. What was unexpected though was the hit that followed it and then a second to her left, both of the unexpected hits overlapping the first two along the bottom, closer to her mark which had so far gone untouched.
Rarity balks a little at the fourth, or tenth depending on how you wished to count them, hit, pulling at her bonds and moving her back legs away a little, looking back over her shoulder towards Twilight, who was grinning again. "Two hits for no response at all." Rarity snorts and looks away again, flicking her tail in annoyance this time.

"... Y-yes."

"Huuuummm? Yes, what, Sapphire?"

"Y-yes I... have been intimate with a stallion. Mistress." The pause wasn't intended that time, she had forgotten it but remembered before it was too long to say it in a manner similar to how she had before where she deliberately paused.

"See, was that so hard Sapphire?" Rarity gives a light shake of her head and the silence stretches for a moment before she's given another pair of quick swats, this time on her gaskins. "None of my questions are rhetorical Sapphire, I fully expect you to answer them all."

"Of-of course mistress. And no, no it was not hard to answer mistress." Twilight smiles, lowering the crop down to her side and nods, walking around Rarity's right again as she talks.

"I knew you were a smart mare Sapphire, a quick study. And it seems you are quite the naughty little filly." Rarity jumps a little when the crop taps the base of her tail, causing it to flick up a little against the object giving a short peek of her normally hidden marehood. Said marehood a little swollen and wet but not to the point of winking just yet. "How many different stallions Sapphire?"

"Two different stallions mistress."

"At the same time?" Rarity snorted at that, and couldn't stop the light giggle that came. That is until the crop tapped her tail base again to remind her of the situation she was in.

"No mistress, not at the same time."

"Ummhum. And mares?"

"W-what about mares mistress?"

"Let me rephrase. Have you ever been intimate with a mare before?" Rarity assumed that was what Twilight meant, but she wanted to see if she could get away with pretending not to know. Or maybe Twilight wanted Rarity to push a little and ask for clarification. Maybe she would ask later but for now she was expected to answer. Again, keep it close to the truth so she could remember it later.

"Yes mistress, I have been intimate with a mare before."

"Just one?"

"I, yes mistress, just one." This whole time Twilight had been lightly tapping the flare of the crop near the base of Rarity's tail. It was quite distracting to say the least.

"Did you not enjoy it Sapphire?"

"No, I, that is, umm, what I mean is that is not a simple 'yes no' question mistress."

"Then give me a more detailed answer Sapphire. I never said you were only limited to 'yes' and 'no'."

"Of-of course mistress. It was not that I did not... enjoy myself with the other mare I just, just, uhh, prefer to be with stallions. Mistress." That crop was now a major distraction, each little tap causing her tail to twitch up and to the side some. Her thighs still had a burn to them but it was very light now, almost not worth mentioning.

"Who was it?" Rarity glances back for a moment then looked away, keeping her mouth shut. The tapping of the crop pauses and after another few heartbeats comes down hard right on the center of her cutie-mark. The first hit there caused her to balk, moving her legs and trying to move away but she couldn't escape from the second hit, on her other mark. Twilight moves back in front of her again. "Well well. Do you have a sensitive mark Sapphire?"

Rarity looks to Twilight, biting her lower lip and settling down again, tugging at her manacles for a moment and moving her back legs so she was not quite standing straight, flicking her tail around to cover her right side as best she could. She, however, did not answer the question.

Instead of giving out more slaps right away Twilight gives a side glance to the cabinets again and reaches out with her magic. Without stopping anything else she was doing she opens a drawer and pulls out two leather cuffs and little metal clips on a short chain. They join the crop as the drawer closes, another one closer to the entry door opening and a coil of white silk rope floats up and out. Rarity watches all of this with wide eyes, twisting her fore-hooves a bit and tugs, looking around before she felt the magic on her horn move down more, washing over her body and once more lifting her up.
She was helpless against Twilight's power, her body moved into position as the leather cuffs opened only to close around her back legs, tightening down to be moderately uncomfortable but not quite painful before her legs were shifted, spread a bit past normal, and the clips attached to the eye bolts in the floor. The magic holding her in place slides up, allowing her to test the clips, which were quite strong and she had little range of movement with the short chain. However she then noticed that the magic was not totally gone, moving to her tail instead.
The water like aura slips over her dock, causing Rarity to shiver some, rolling down over her tail and pulling the normal curls into something a bit straighter. Rarity cringed a little, not because it was painful, in fact she could barely fell anything but some pleasant little tugs, it was that it took her hours to get the curls just right in her tail. And for some reason the thought of all that hard work being so casually undone made her a little more aroused.
The silk rope uncoiled and starting to wind into her tail hair, forming a braid. Rarity watched it happen, fascinated with the grace Twilight had with her magic even without having a good line of sight. It didn't take long before her tail was entwined with the rope, the trailing edge of said rope going through the third eye bolt, pulling her tail down and straight in such a matter that lightly pulled on it and if she tried to move too much would cause slightly more painful pulls.

Now that she was fully bound Rarity looks back to Twilight, whom had a neutral face unless you looked into her eyes. They had a light shine to them, showing that she was quite enjoying herself. Rarity felt her face flush a little when she realized that she too was enjoying herself, the constant tugging on the rope as her tail tried to flick to the side evidence of that.
Twilight then slowly moves the crop over, placing it on Rarity's right gaskin and running it up, over her cutie-mark and to her dock. The act made Rarity shiver in pleasure and bite back a moan. The crop goes down from her dock over her left mark to her gaskin before lifting up and swatting closer to her flank then the last hit but, as before, over lapping with the previous. There is a hit closer to her rear, and then a matching pair in the same order on her other side. Each hit caused her to balk, tugging against the cuffs and causing them to dig into her flesh and the metal jingle from her movement. Also she was tugging hard on her tail, which just feed into more movement.
Finally the hits stop and she is given a moment to calm down, at least a little. Her breathing was coming in short and fast though her nose and her whole body felt warm, especially her thighs that burned from the crop. She could also fell that her inner thighs were starting to get a little wet.

Rarity was not quite the dripper that Twilight was, or at least to the level she said she was in her story. If asked she would deny it of course, but Rarity was becoming sexually excited from all of this. It was so, trilling, in a way. Being at the mercy of her friend, someone she trusted. Yet, she knew that if it became too much she could end it all with a word. Only now did she truly understand the power of that safe word. Though, at this rate, she was not sure she'd ever need it, at least not tonight. Twilight was ramping things up, but slowly. Unless she did a big leap Rarity felt it safe to assume tonight would be safe-word free.

"Two extra for good measure since you are actively being stubborn. Now, again Sapphire. Do you have a sensitive cutie-mark?"

"Yes mistress, though it is rather obvious now is it not?" The hits were swift and rough, along the bottom edge of her cutie-marks, causing her to gasp and tug on her bonds again. Those were obviously from 'back talking'. Just as planned.

"Yes, well. Now, the other question. Who was the mare you were with Sapphire?" Rarity looks to Twilight again, and looks away.

"I swore not to tell anypony who it was, no matter what you do to me I will not break that promise." Twilight makes her little tut sound and delivers two slaps to the top of Rarity's cutie-marks, these not getting as large of a response as before.

"Very well Sapphire. I shall respect that promise, for now. You will answer me some day. Tonight is merely an... introduction. Not an interrogation, despite what it looks like. Are you sexually excited Sapphire?" Twilight was quite good at throwing out questions in such a manner and time that they caused confusion. This time was no different. It took Rarity a moment to even fully understand what had been asked of her. Her face flushes again and she looks away.

"N-no mistress." The two swats that come dead center of her thighs get her to jump and whine some from pain, wiggling once the sharp stings bleed into warm pleasure.

"Two for blatant lies Sapphire. I can smell your musk and even while bound your tail gives you away. So, I ask again, are you sexually excited?"

"Y-yes mistress."

"Yes, what, Sapphire?"

"... Yes I am sexually excited mistress." Being forced to admit it made Rarity blush like a school filly. She could fell her whole face flush and fur fluff up in response to the blood flow. Twilight could clearly see the red skin under the white fur.

"Huuummm. Now the question is what should I do about this? Don't answer that. On the one hoof you have been quite agreeable for the circumstances yet on the other you've been a bit obstinate, but, again this is very new to you. What do you want to do about it Sapphire?"

"Uhhh, I-i do not know m-mistress." Rarity had no idea what do about the itch between her legs. She had very little experience with another mare and in this situation only had what she could gather from the story Twilight had told so many nights ago. Her forelegs could easily be pulled up more to give frontal access or her tail could be pulled up if untied from the eye bolt in the floor. It was this latter option that Twilight chose, wrapping her magic along the rope and undoing the knot, pulling it straight back for a moment then up, over Rarity's head and securing it once again, this time to the chain attached to her forelegs. Rarity feels her face flush even more as the cold air of the room touches her haunches, now exposed for all to see.
And see Twilight does as she walks around behind the white mare, making a sound of appreciation at the sight. Rarity tugs her tail a bit, trying to flick it down again but the rope was too strong of course and her magic was still being suppressed, Twilight really showing why she was Celestia's personal student by keeping up such a spell for so long while doing other, rather distracting, tasks.

"I think you deserve a reward for being such a good girl Sapphire. But I am going to give you an order so listen closely. I want you to remain as quiet as you can Sapphire, not a peep, understand? Speak your answer then follow the order." Rarity bites her lips, working it with her teeth some. She wasn't really a 'screamer' or all that vocal in her love making but she had been told she made small little sounds when enjoying herself, sounds she had no real control over. This might be a hard order to follow but she could try at least.

"I-i understand mistress, you want me to remain quiet." Twilight makes a light sound of acknowledgement before moving close and pressing her knee between Rarity's thighs, the other mare biting her lips as well as biting back a moan of pleasure. She was so hot back there. She had not felt such a need to be touched in that spot in quite a while. Outside of her estrus cycle that was.
Twilight keeps her rubbing light, teasing Rarity some. She enjoyed watching her friend wiggling and hearing her fighting, and failing, to not make any noise. She especially liked the little squeaking sounds that happened when she ever so slightly brushed against the swollen clit. So she did that often, but not too often. Moving back Twilight grins some at the small whine Rarity couldn't suppress, that sound a bit too loud to ignore so she gives each set of three gem stones a smack with her crop.
She then moves the crop back, rubbing the leather over Rarity's smooth folds, the white mare bucking back at the touch and gasping, all thoughts of keeping quiet forgotten. Twilight bites her tongue to keep from giggling and flicks that pink pearl of flesh with the crop, getting an even louder gasp and buck from Rarity.

"You are not staying quiet Sapphire. And I do not think a hit to your mark will get the importance of disobeying my order across." Rarity's brain was a little too fuzzy to fully process what Twilight was saying but when it did he eyes shot open and she turned her head some, safe word ready but when she locks eyes with Twilight she bites her lip again. Boundaries were made to be pushed, and if Twilight thought she could take it Rarity would give it a try. The purple mare smiles lightly and brings the crop down on her target, that swollen pink nub of flesh, making sure to really press in and drag down at the same time but not hitting it too hard.
Rarity's eyes widen again, arching her back and neck, crying out as the pain flashed though her body. But it faded quickly and was replaced with a pleasant warmth, a warmth that spiked when she felt soft lips on her pearl, Twilight 'kissing the wound'.
Twilight also brought up her hoof, rubbing the hard part against Rarity's labia and flicks her tongue over the clitoris before biting down on it and dragging her hoof down the puffy lips. That was the breaking point, Rarity's whole body charged with pleasure and pain in such a mix she found it hard to tell them apart. Throwing her head back and calling out her pleasure while pressing hard against Twilight's face as she climaxed.

"AH! TWILIGHT!" All thoughts of the play and of keeping silent forgotten in her peak. She was so lost in her high she hadn't noticed that Twilight had dropped the magic suppression and her own horn was glowing a bright light blue, but she did not however have, as it was colloquially known, a 'horngasm'. Not every unicorn did and Rarity was not a 'squirter', on either end.
Twilight keeps licking, drinking up what little juice there was. Like most things Rarity was not a messy pony. And it had very little taste to it, at least nothing to really make note of, which was fine for the purple mare but she'd casually suggest some various fruits that where both healthy and might influence the taste for next time.
Once Rarity could not go any farther she slumps against her chains, knees finally giving her on her. Twilight wraps the white mare fully in her magic again while at the same time undoing all the bonds and slowly lowering her to the ground. She lays down next to her, nuzzling her face some and Rarity weakly pushes back, ignoring the light amount of her own essence being rubbed into her fur from the nuzzle and the scent it brings along, there was even a smile on her lips.

"Have fun?" The kiss caught Twilight by surprise but was all the answer she needed to her question. Once it was done Rarity catches her breath and sighs.

"So sorry for breaking character darling, but-" She was interrupted by a kiss herself this time, closing her eyes and enjoying the feel of those lips against her own. The light taste of herself didn't bother her in the least. This one was shorter, and Twilight was the one to pull back first.

"It's ok Rarity, it happens sometimes. Come on, let's clean up and talk about the session." She stands, holding out a hoof to help Rarity stand as well.

"What's there to talk about darling?"

"It is a good thing to talk about each session afterwards, what you liked and didn't like. It will allow us to improve on each session and make the next one better."

"Ah, yes, of course, wonderful idea darling." The two of them head back to the showers, cleaning up and talking about what just transpired before they went back upstairs and snuggled together into Twilight's bed for the night.

Author's Note

Ok, I'm a lying liar who lies. On a few things. One is that, again, no editor when I said I'd let KoC look over this chapter. I just wanted to get this out since it had taken so long and I'm not even sure if that offer is still good since I took so long. I probably won't be using an editor and just going over it again after I post.
Second lie is I haven't done that rewrite on the previous chapters yet. I finally had some inspiration for this one and felt it was best to work on the new instead of the old. I'll get around to that edit. At some point. Maybe.

I had a bit of a writer's block with the Twilight/Sunrise-Rarity/Sapphire interactions.
Twilight has a lot of experience of the years with various personas, and quite a lot with this particular one her(it?)self.
Rarity, however, has never done any sort of acting (save her 'prompts and airs' practice for when she becomes famous and gets into The Elite) before and is thus walking a fine line between the truth and an illusion. I had to carefully balance what was "Rarity" and what was "Sapphire" and at the same time balance what was "Rarity being Sapphire" and was "Rarity being Rarity". AND I had to balance both Twilight and Rarity to match at least somewhat to their cannon personality. The AU tag will only get me so far with that, and Twilight is going to be the largest departure in these starting chapters for obvious reasons (mainly she's not so OCD about things, because she got laid by Celestia.)
Coming into this chapter (and in preparation for later ones) I knew my version of Rarity was going to be into "messy play", the type of thing that ruins her looks and all the work she puts into them. But then I came to realize that she is very much into pain play and is going to have an abnormally high threshold for it so it'll be fun testing her limits, physical ones, mental ones and personal ones.

Also I wasn't sure how I wanted things to flow and I rewrote some small scenes a couple of times trying to get the "feel" right. I'm happy with how this turned out, at least for now. We'll see how long that lasts.

Well, I hope it was worth the wait, I mean this chapter is more than twice the size of all the previous ones. I'm going to try to keep things in the three to sic thousand word range because I know the longer chapters are a bit of a chore to read. So some things might be broken up into two like these first two chapters.

Work on Chapter Three has begun, but like with this one I've hit a bit of a wall on a few sections on how to get information needed across without it becoming just exposition for the sake of exposition. I am also working on an "extra" for the story, which will include a timeline of sorts as well as character bios.

No telling how long all that is going to take. Other projects have been calling my attention, both personal and professional. A few of these other projects are other pony stories, but none of them are BDSM focused. Not sure when any of them will see the light of day.

Oh well, back to work for me.
