"Twilight, please, be reasonable..."

Twilight nuzzled her wife, letting herself be tickled by the soft hairs of the fur trim around the collar of her cloak. "Aww, Rarity, I really wanna do it tonight."

They entered their bedroom, and Rarity shivered as Twilight peppered kisses along her neck. "Darling, I simply can't." She gave Twilight a weak smile. "You already indulged yourself last night, if you recall."

"I know." More kisses. Twilight began nipping at her too, quick, playful actions that left Rarity trembling. "And I'm so happy that I got to do that yesterday. So, so happy. But I want it again today."

"I..." Rarity faltered, and Twilight struck at the revealed weakness.

"You want to make me happy, right?" Twilight pulled back, giving her a wide-eyed gaze that pierced her soul. "I love you, Rarity, with all my heart."

"I love you too, Twilight." Rarity tried to bow her head, but Twilight lifted her chin up with a hoof, keeping their eyes locked on each other. "And I do want to make you happy. Really, I do."

"Then do this for me," Twilight demanded, allowing her tone to harden just a little. "Serve your princess like you promised to at the altar all those years ago."

"But I don't want to," Rarity whined, pulling her thick blue coat tighter around herself.

A flash of anger flared up in Twilight as she saw the gesture. Struggling to keep her tone even, she said, "you don't have to have to hide yourself in here, Rarity. There's no one to judge you, no one to ask any awkward questions. No one to stop you from being a good little mare for me."

"Don't make me do this..." Rarity begged as Twilight's grip on her chin tightened. "It hurts. It hurts so much."

"I know," Twilight said softly, her voice soothing and layered with sweet honey. "But I like hurting you, and you like making me happy, right?"

"I do," Rarity admitted, the fear permeating the air serving as a most potent aphrodisiac.

"And you love me." It wasn't a question. "You love me so much that you'll let me hurt you again tonight."

Rarity tried to shake her head, but Twilight's grip was too strong, and eventually the fire in her eyes dimmed. "Please," she whimpered, the resistance fading from her tone. "I don't know if I can take any more."

"You can and you will." Once again, there was no doubt in Twilight's voice. "Because you'd do anything for me."

Her hoof drifted downwards towards the cloak, undoing the clasp that held it around Rarity's neck. Rarity didn't try to fight back as she parted the fabric and pushed it off her body, revealing the product of the many years Rarity had spent under Twilight's tender mercies.

Layers upon layers of scars decorated her body, coming from a generously diverse sampling of sources. Lines of darkened flesh crisscrossed her torso, the product of many long nights under the cutting bite of blade or whip. Interspersed between these were a multitude of pockmarks, like freckles all across her barrel and withers. Twilight still remembered the sweet smell of burning flesh as she had pressed burning hot embers against those points to create those marks.

Dark splotches scattered about Rarity's white fur where it had been bruised, evidence of last night's activities. Twilight sighed in contentment as she beheld the centrepiece of her years of work on this canvas: her starry cutie mark branded onto the center of her belly, marking Rarity as hers, now and forever. They had spent so many wonderful nights together, and Twilight couldn't wait to get started on yet another promising evening.

"Lie down, my love."

Still shaking, Rarity allowed Twilight to gently push her down onto the floor, where four leather cuffs jutted out. With heartrending tenderness, she rolled her over onto her back and exposed the full extent of the masterpiece Twilight had wrought to the princess' hungry eyes. Purple hooves guided white ones as Twilight carefully set each of Rarity's legs in place, locked within one of the cuffs and leaving her spread-eagled and completely vulnerable. Just as she liked it.

"You're so beautiful," Twilight whispered, overcome by the sight that was presented to her. "Every night before I go to sleep, I thank my lucky stars that you're in my life, that you chose to share yourself with me completely, and devote your life to making me happy."

She lit up her horn, dispelling the illusion spell she'd placed on the far corner of the room and revealing a velvet-lined multi-tiered cart carrying several wooden trays filled with all sorts of toys and other equipment that had both mares' imaginations flaring up in full force.

Twilight pulled the cart over with her magic, lifting the first and most important item on the cart: Rarity's wedding ring. "I still remember the day you gave this to me," she said, picking up the diamond-studded band with a hoof. "Do you remember what I said when I proposed?"

Rarity nodded, her eyes wide with fear as she tracked the movement of the ring towards her horn. "You asked me to make you the happiest mare in Equestria," she whispered, her breathing shallow and strained.

"And you did." Twilight slipped the golden band over the unicorn's horn, and Rarity winced as her connection of the aether was cut off. "I'm glad we decided to enchant the ring after the ceremony to suppress your magic. It's so nice to start out our sessions with a symbol of our everlasting love, right?"

With her wife properly restrained, Twilight took the opportunity to give her a quick but passionate kiss, dominating her mouth with her tongue. At the same time, her right forehoof began to slowly slide up Rarity's thigh, tracing an erratic path across her fur that had Rarity shaking at the thought of what was to come.

"Let's get you warmed up, shall we?" The hoof reached the juncture of Rarity's thighs as Twilight pulled away from the kiss, her gaze drifting downwards to the beautiful flower presented to her. With expert precision, she began tracing circles around the unicorn's nethers, alternating between light and heavy touches that she knew would drive Rarity's arousal to a fever pitch.

Rarity gasped as Twilight finally ran her hoof along her folds, and then moaned when she slid upwards to press against her clit. Already, her ministrations and began to have their effect on this body that Twilight had learned to play like an instrument, the first signs of wetness staining her glistening folds. She continued to play with her wife's marehood, sometimes tracing slow circles around her clit, and sometimes teasing deeper inside of her with her hoof.

Eventually, Twilight pulled back, admiring the sheen of arousal coating her hoof. "You're already so wet for me," she teased, giving her hoof a long lick and savouring the taste of her one true love. "Don't you love how I can make you want me, even when you think you don't?"

Her horn lit up again. "Now, I think it's time we gave you something to occupy yourself with down there, don't you think?"

Rarity tried to turn and glance at the cart, but Twilight had positioned it out of her view. "Please, I can't," she begged, her thighs trying to clench together and hide what was rightfully Twilight's. "It still hurts so much from yesterday."

"Shh..." Twilight gently stroked Rarity's cheek. "It's okay. We're not going to do anything crazy with your pretty little flower this time." She floated over a medium-sized dildo and a bottle lube for Rarity to see. "See? Nothing too big, or oddly shaped, or covered with spikes or anything." She began pouring a generous amount of lubrication on the phallic object. "And I'm going to make sure it goes in nice and smooth, okay? I'm not going to hurt you there tonight, not like last night." She smiled at the memory of Rarity crying as she'd shoved the unlubed monster she'd left on the tray this time inside of her during their previous session.

Once again, with great tenderness, Twilight parted Rarity's folds and slowly slid the dildo inside of her, inch by agonizing inch. She made sure that she never pushed her beyond mild discomfort, and was rewarded by a lewd moan of pleasure as she finally hilted it inside her fully.

"There," she said, pulling her hoof back. "That wasn't so bad, was it? You're enjoying this, right?"

Rarity nodded. "Thank you, Twilight." Hope flared in her eyes, a sweet, naïve look that had Twilight's heart skipping a beat at the sight.

"Of course." Twilight began rubbing against the bound mare's clit once again, eliciting a delightful symphony of gasps and cries. "You know I love giving you pleasure." Her magic reached out to the cart once again, wrapping itself around the next object in their little scene. Twilight met Rarity's hopeful eyes with her own as her lips twisted into a sadistic smile. "It makes the pain even sweeter after I take it away."

With that, she pulled her hoof away and floated over the implement she'd taken from the tray in front of Rarity's despairing eyes. It was a silver-bladed knife that glittered in the torchlight of the room, casting an aura of menace as Twilight slowly spun it around for Rarity to see.

"No," Rarity whispered, pleading with her wife as her whole body stiffened. "Not that. Please, anything but that."

Twilight rolled her eyes. "You say that every time. Doesn't matter if it's the knife, the whip, the embers, or something else. It's the same pattern every time, like clockwork, or a well-planned schedule. You beg me to stop, and I don't."

"I mean it this time." Rarity tried to shift away from the dancing blade, but her restraints held firm.

"That's part of the pattern too," Twilight noted. "You always mean it." Her smile widened. "And I never listen."

The first cut appeared on her belly before Rarity had time to process the words. Years of practice couple with Twilight's magical prowess had given her the perfect control needed to make an incision as exactly the right depth to sting, but not to cause permanent harm. Rarity winced but did not cry out — Twilight had trained her far too well for something so small to affect her so greatly.

As the first drop of red beaded against her white fur, Twilight felt an answering wetness well up within her sex as her arousal flared in anticipation.

"I know I probably don't have to say it, since you're the fashion expert here, but red really does go well with your coat." Twilight bent over to press a quick kiss against the wound, taking Rarity's life essence within her.

The flat of the knife trailed up across Rarity's barrel, the cold silver sending tremors across her body. Twilight stopped as she reached an old, faded mark between her upper ribs. "Do you remember when I made this?" Twilight asked, the tip of her knife prodding at one edge of the scar. "I was so inexperienced on our wedding night. I didn't actually mean to hit hard enough to leave a scar.

"But it felt so good when you screamed and bled." Twilight raised the knife for a second. "Will you scream for me again, Rarity?"

With that, she plunged the blade into her lover and dragged it along the line of the original scar, deep enough to make Rarity cry out, but not so deep as to do any lasting damage. Twilight had been inexperienced on their wedding night, but she'd gained so much skill since then.

"Stop!" Rarity gasped out, tears forming around her eyes. "Twilight, please, stop!"

"But Rarity, we're just getting started." Twilight's hoof returned to pleasuring Rarity's marehood, keeping her locked in a mixture of pleasure and pain. The urge to masturbate was growing stronger by the second, but Twilight chose to savour the burning arousal in her loins rather than provide herself relief. There would be time enough for that later. "We're going to have so much fun tonight. I can't wait!"

A drop of blood fell from the tip of the knife onto the carpet as Twilight admired her work. Her hoof slid upwards as she traced along Rarity's old scars, until she was right under her previous cut. "You know," she mused, bringing down the blade once more, "all these burns look almost like stars against the night sky in negative. And you know what the best part of stargazing is?

"Finding constellations in them." Metal bit into flesh, connecting two of the dots on Rarity's body.

It was difficult keeping her path steady as Rarity thrashed wildly against her bonds, her head whipping back and forth as she let out the most exquisite screams of pain. Still, Twilight prided herself on her magical dexterity, and inch by inch she carved her way through Rarity's flesh, going from point to point as left a bloody trail of red in her wake.

Her hoof returned to its potions against Rarity's nethers as she alternated between pumping the dildo within her in and out and teasing her clit with expert precision. Meanwhile, her own arousal reached a fever pitch as Rarity's screams turned into groaning and moan of agony as she weakly pleaded with Twilight to stop, begging her for some relief from the torture she was inflicting on her. It was a beautiful symphony of desperation and suffering sung in a cultured tone that served as the most erotic music Twilight had ever had the pleasure of listening to.

"Does it hurt?" Twilight asked as she drew one particularly long line upwards and to the right. Feedback was an important part of improvement, after all.

"Oh, Celestia," Rarity whimpered. "Make it stop. Please make it stop. It hurts so much."

"I'm glad to hear that," Twilight said, rewarding her captive by pressing hard against her clit and drawing out a lewd moan from Rarity even as she continued to gasp in pain from Twilight's artistry.

Finally, she reached the end of her travels, lifting up the knife and admiring her work. Against Rarity's snow-white fur, a red constellation had been carved into the upper-right part of her barrel, slowly seeping with blood that dripped down her side.

"There we go," Twilight said, lifting her hoof away from Rarity's sex as well. She didn't want to give her any pleasure without pain right now. "A near-perfect replica of The Chained Maiden." She giggled. "Pretty apt, huh?"

Rarity was still panting as agony ripped through her body from the fresh wounds. "I can't," Rarity sobbed. "I can't take any more. I'll do anything. Anything! Just let me go, please."

"I can't do that, silly." Another chuckle, this one much darker and more sadistic. "I only did one constellation. There's a whole sky out there to explore, and Luna would be very sad if we stopped now, don't you think?" She pressed a kiss against Rarity's muzzle, tasting her sweat and fear on her tongue. "I love you so much, Rarity. Thank you for letting me enjoy your suffering like this."

"No, Twilight, pl— aah!" Rarity's begging was cut off as Twilight began slicing the second constellation into her skin.

"Ooh, I remember this one," Twilight commented as she cut across a series of parallel scars. "That was the first time I used the cat o' nine tails on you. I came so hard when I sliced your delicate little flower open with it while you were eating me out." She shuddered at the memory, and saw Rarity do the same. "Maybe we can do something similar this time, but this time I can shove this knife up your marehood while I have your muzzle pressed against mine."

Rarity let out another sob at that, mewling pathetically as she shook her head. It was a most erotic vision to behold, and Twilight grinned widely as she pivoted her blade and began making multiple lines emanating from the same point, like rays of the sun. With each new cut, Rarity moaned and cried out at Twilight to show her mercy.

It was positively euphoric to deny that request.

"And that's Scorpio," Twilight announced as she finished the second constellation. "I figured it was relevant since scorpions and stings, you know?"

Rarity sniffled. "Are you done yet?" she asked dully, hope already faded from her eyes.

"Of course not!" Twilight announced happily. "I'm enjoying myself so much I don't ever want to stop." Her eyes narrowed. "I'm never going to stop hurting you, Rarity, because you're my soul mate, which means I get to do whatever I want to you, and you just have to endure the agony because you want to let me."

A nod from Rarity. Aww, it looked like her spirit was already starting to break. Oh well, that didn't make her screams any less pleasurable to the ears.

"I think I'll do Fornax next." Amidst those screams, Twilight continued speaking conversationally. "It means 'The Furnace.' I didn't prepare any coals today, and the alloy in this particular blade doesn't really bind to heating spells that well, so I won't be able to do anything with temperature play today unless I decide to freeze some water. Isn't that disappointing? Tell me how disappointed you are, Rarity."

"I don't want—" Another cry of agony was ripped from Rarity's throat as Twilight pinched tightly on Rarity's clit while continuing to carve up her flesh.

"I said, tell me how disappointed you are that I won't get to burn you tonight." The edge in Twilight's voice was as sharp as her blade, and Rarity quickly acquiesced.

"I-I'm sorry you won't have the p-pleasure of searing my flesh t-tonight." The words were a stammered mess, but they were good enough for Twilight, who smiled and returned to her previous ministrations against Rarity's marehood.

"Good girl. You like giving me pleasure, don't you?" Twilight pressed on, needing to feel Rarity's submission in her soul. "Even if it hurts you."

"Yes," Rarity whispered, "I'd do anything for you, my love. But please, I beg of you, don't make me endure this any longer."

Twilight paused, letting silence fill the room as she pretending to consider her answer. "No," she said, watching the light in Rarity's eyes grow even dimmer at her refusal. Her own sex cried out for attention at the sight, pleading with Twilight hoof herself to what would be an earth-shattering orgasm at this pathetic and lovely sight, but Twilight had learned the value of generosity from one of its paragons, and she would not be the first to achieve release tonight.

For the next constellation, Twilight chose The Arrow, partly to continue the theme things that caused pain, but also because it was the simplest constellation she knew. In fact, it was so simple that Twilight could draw it without even looking at Rarity, which was perfect for what she had planned.

As the blade plunged into Rarity, Twilight sidled downwards and captured the nub at the base of her marehood with her licks, suckling lightly on it. At the same time, she began to thrust the dildo in and out of Rarity with renewed vigour, making sure to angle the toy to stimulate the most sensitive parts of Rarity's passage.

She was rewarded with a hoarse scream that echoed through the room as pain and pleasure both rose to new heights within the unicorn. "Come for me, Rarity," she commanded, licking and sucking and pumping and using all her expertise to drive Rarity over the edge.

The knife completed its path, and Twilight lifted it up just as Rarity did as instructed. Her nectar was sweet ambrosia on Twilight's tongue, and she made sure to lap up as much as she could as she continued pleasuring her wife, a sense of satisfaction settling into her heart at the knowledge that she was giving so much to Rarity.

"See, you enjoyed that one," Twilight said as she rose up to view her handiwork. She'd followed the pattern in her mind exactly, creating yet another bloody constellation in this field of stars. By now, the others were also starting to run and smear, but Twilight could fix that later.

The Twins followed The Arrow, with Twilight whispering sweet nothings into Rarity's ear about how they were two souls intertwined with one another, and how Rarity was fated to devotedly serve Twilight's desire and to submit to her tender mercies. Rarity was Twilight's, and she made sure to remind her that no other pony would ever want her like Twilight did, would ever love her like Twilight did. There was no other option for her but to obey Twilight.

Finally, Twilight finished off by carving The Virgin into her wife right above her marehood, an ironic joke that had her snickering as Rarity cried silently in defeat and gave herself over to the pain.

"There, all done." The tone Twilight used was soft and comforting, like a doctor to a child after a nasty injection. "You look so beautiful right now, you know that?"

It was true. Even through the haze of blood, the lines of the constellations stood out starkly against Rarity's fur, a twisted homage to Luna's work. Rarity twitched and moaned under Twilight's gaze, causing the six patterns to pulse and release even more of her life essence. Twilight would need to act quickly before she lost consciousness, if she wanted to achieve her own release tonight.

"You've been so good," she cooed at her lover, stepping over her and turning around so that she could still see her painted canvas while her dripping sex hovered over Rarity's muzzle. "Now I just need you to do one more thing, okay?"

"No more..." Rarity whimpered, her voice as raw as her wounds. "Please, Twilight, I can't take any more. I beg of you, have mercy on me, my love."

"It's okay," Twilight said. "All you need to do now is show me just how much you love me."

With that, she lowered herself onto Rarity. Despite her exhaustion, Rarity instinctively stuck her tongue out, lapping at Twilight's marehood with practiced, if slightly weak and sloppy, skill. Twilight had trained her well, and was reaping the fruits of her labours as that tongue dove deep inside of her, hitting all the sensitive parts of her inner walls.

"Oh, yes, just like that," Twilight said breathily, thrusting in time with her wife's ministrations. "Show me how much you love me. I want to feel your devotion to me, Rarity."

She let out a lewd moan as her hoof slid downwards to pleasure her own clit, amplifying the pleasure Rarity was giving her. As she did this, she looked down at the final masterpiece she had created this night.

Six bloody constellations spread out before her view, each one a symbol of Twilight's conquest over that beautiful white body of hers. Virgo, the Maiden, as Rarity had been when Twilight had first introduced her to her darker pleasures. Gemini, the Twins, bound together in the stars for all eternity, just as Rarity was bound to Twilight.

"This is where you belong," she groaned, hoofing herself faster. "You are mine, all mine, in every way possible." Rarity moaned her own submission in response, and Twilight continued her visual journey across her wife's body.

Sagitta, The Arrow, which had pierced Rarity's flesh and released her essence for Twilight to partake in and further stake her claim. Fornax, the Furnace, burning Rarity skin and making her scream for mercy that never came, that only served to inflame Twilight's own passions. Scorpio, the Scorpion, whose sting Rarity had felt many times as Twilight slowly moulded her into the perfect soulmate, ready to serve her every desire.

And finally, Andromeda, the Chained Maiden. Twilight had bound Rarity to her will with the power of their love, but she still had yet to chain her wife to herself for all eternity. Tonight, she fixed that.

"I love you so much, Rarity," Twilight said sweetly, with heartwarming tenderness that outshone even her wedding vows. "I want you to be with me, now and forever. And I know you want that too. You love me enough to do anything to me, to let me inflict unimaginable pain on you because I like it, because it makes me happy."

She was so close to the edge. Rarity's tongue and her own hoof had built up the pressure in her loins into dam just moments away from bursting. With her hoof, Twilight picked up the silver knife once last time and, releasing a wild cry of ecstasy, sliced her lover's throat open, spraying out her life force into the air.

Rarity gurgled, but Twilight's magic held her head in place, and her complete and utter devotion to Twilight had her desperately swirling her tongue inside Twilight even in her death throes. Twilight herself was in a heaven unlike any other, pure pleasure flooding her senses as she took Rarity's life to fuel her own release. Wave after wave of euphoria crashed down on her with every spurt of blood with the severed artery below her, and Twilight ground her sex harder into Rarity's muzzle as she nearly rubbed her clit raw with her hood.

She had no idea how long they stayed like that, two lovers intertwined in the ultimate act of Generosity, pulsing agony and ecstasy mingling together with the joined souls, so that it was impossible to determine when one ended and the other began.

Eventually, the high began to dim, the last of the aftershocks fading out and Rarity's head finally lolling back unnaturally her lifeless body slumped against the floor. Twilight took a moment to collect herself before quickly casting a preservation spell. With her masterpiece completed, it was time to ensure that Twilight could enjoy it for the rest of her eternal life. No longer would Rarity wither away and drifted away from her. Now, she would be Twilight's for beyond the end of her days.

Breathing out a contented sigh, Twilight picked up the body and nuzzled Rarity's lifeless cheeks. Tomorrow, she would have to clean all this up and invent a story of a tragic accident and pretend to be sad that she was parted from her beloved forever, even if Rarity was going to be staying right here in their bedroom. But tonight, she could spend time with the mare who made her happy, unlike anyone else had.

"This is how it was meant to be," she said, enjoying the softness of her skin and revelling in Rarity's essences that she was covered in, enveloped in, ensorcelled by. "You and me, forever and ever, just like you promised me on the happiest day of our lives."

She pressed a kiss against her cooling lips, tasting her soul on her tongue. It tasted like blood and Twilight's release, just like it should have. "I love you, Rarity. And I'll never stop loving you, no matter what. Just like how you'll never stop loving me."

As Twilight settled in beside her lover, the stars shone brightly in the night sky. "Dream of me in your eternal slumber," she commanded her beloved, and then drifted off to sleep, ready to embrace the wonderful future ahead of them.
