Everything will be perfectly fine, Twilight. She buried her muzzle in her book again, trying to ignore the way the train lurched and swayed as it climbed up towards Canterlot. That wasn't the only thing she was trying to ignore. Her increasingly outlandish fantasies still plagued her. That was why she'd chosen a book on mathematics to read on the train. It was probably safe. Unless she started fantasizing about how sexy the fractions looked with their denominators lying below the numerators like that. She sighed. Absolutely everything seemed to be a path to thinking about doing terrible things to Lune.

It had gone beyond even fantasizing about having him helpless. Since the last time he'd visited she'd been thinking about him begging, kissing her feet, pleading that she do things to him. A few times of late she'd even caught herself thinking about hurting him, making him beg and plead with her to stop.

How could she think about such things? How could she get aroused at the idea of hurting somepony? Especially somepony she loved? At least they're just thoughts, right? I wouldn't actually hurt him. It'll be fine, won't it?

The jolting of the train began to slow. They were almost there. Twilight rose and stowed the book in her saddlebags. No sooner had the train stopped than she'd trotted briskly off it. Lune was there, waiting at the station. Twilight practically flung herself at him once again.

He folded his wings around her as she clung to him. "Another difficult week, love?"

"Something like that."

"Would lunch reservations at the finest dining establishment in Canterlot improve thy mood?"

"I think it would." Twilight smiled at Lune.

"Then let us proceed."

They walked side by side through Canterlot. A few ponies stared. Twilight was getting used to that by now—one of the hazards of dating royalty. She was technically royalty as well, of course, but she was not nearly as noticeable as a giant alicorn with a flowing, magical mane and tail. With her wings folded she looked almost like a normal unicorn. But even with how visible Lune was, most ponies left them alone. It had actually been much worse a year ago when Lune had first made the announcement that he was no longer Luna. The final change had only happened a couple of weeks past, but by then Lune had been wearing an illusory stallion’s form for so long that few ponies had paid much attention to the actual change. Even though it had made him almost half again as tall.

There's some kind of lesson there, I'm sure, about what ponies find important, thought Twilight idly as they walked. She was glad to finally have her mind settle on something, anything, other than what it had insisted on thinking about recently.

Cheerful conversation with Lune during lunch also kept her occupied with safer thoughts. Soon she had managed to actually relax. The food was excellent, the service was superb, and the company couldn't be better. She left the restaurant smiling and feeling much improved. The earlier tension, however, had left her with a sore neck and a hint of a headache.

"I have secured the entire day, and this night as well, with no duty to divert me from thy company, Twilight. Hast thou any suggestion for how we might pass the time?"

Twilight rubbed at her neck, not having much trouble coming up with one idea. "What about a visit to a spa? I've come to quite enjoy the Ponyville spa, I'm sure there must be at least one spa here that's as nice."

Lune cocked his head to the side, thinking about that. "Feeling a need to relax?"

Twilight nodded.

Lune winked at her. "Perhaps I could assist? I have some experience with massage."

Twilight raised her eyebrows. "Oh?"

"Yes indeed." Lune wiggled his eyebrows suggestively in return.

Twilight snickered. She probably shouldn't just retreat to Lune's rooms and dive straight into what would probably turn out to be an excuse to have sex again. They ought to spend some time doing other things. Then again they'd spent a whole year dating, doing other things. So why not?

"All right. Let's go."

"Indeed, let us." Lune's horn lit, and before Twilight could ask what he was doing they vanished in a flash of light, to reappear on Lune's balcony.

"You don't waste any time, do you?"

"Wouldst thou rather have walked?"

"Well, I suppose not! So... about that massage?"

Lune smiled and gestured grandly towards the bedroom with a hoof. "Lead on, and I shall follow thee."

Twilight made her way into the bedroom, where she sprawled out on her stomach on the spacious bed. Lune climbed in beside her and ran a hoof down her back. "Where is the tension greatest?" he asked.

"Right at the back of my neck," said Twilight.

Lune nodded. Then next thing she knew he'd straddled her, sitting carefully atop her thighs, and reached forward to press his hooves gently against the back of her neck. This didn't bother her the way being completely pinned under him had, thankfully. She sighed as his hooves pressed into the sore muscles there, and tried to relax.

He was very good. His hooves pushed just hard enough to knead at the knots in her neck and back, but still gently enough to not hurt. Twilight moaned and relaxed further as he worked slowly up and down her back. She was soon completely limp and practically purring. Lune began to concentrate his massaging at the bases of her wings, which was good in a different sort of way. She found herself spreading them out involuntarily. She didn't protest, she just let out a soft moan of pleasure as he ran his hooves along the leading edges.

Next thing she knew he'd bent his head and was gently preening her feathers. Twilight felt that she was being reduced to a puddle of goo, but in the best possible way. The preening felt every bit as good as the massage had. Lune paid attention to every single flight feather, and carefully groomed most of the smaller feathers as well. When he finally finished, Twilight heaved a deep sigh, rather regretting that he was done. He didn't make any move to get up though, instead he returned to caressing along the leading edges and down to the bases of her wings. Twilight moaned. There was a sweet spot, right at the spot where wing met back, that was incredibly sensitive. Lune knew just how to hit it, and soon Twilight was starting to feel the warmth of arousal building between her legs.

Lune nuzzled just behind one ear, whispering softly, "Shall I continue to attend to thy back, or wouldst thou rather turn over and I attend to thee in other ways?"

"Mmm. I think my back is more than fine now," said Twilight.

Lune chuckled and climbed off of her, letting Twilight roll over. He bent and kissed her with gentle passion, while one hoof stroked down her body, over her belly, teasingly close to the spot where her slowly kindling need was centered. Twilight didn't want to be teased, though. "I think thou shouldst attend to me, as thou hast promised," she said when he broke off the kiss.

Lune didn't answer with words, but he slid his hoof lower, brushing it between her legs, and that was answer enough. Twilight spread her legs apart, taking a deep breath as Lune's hoof slowly caressed her. "That's better," murmured Twilight, letting the breath out with a blissful sigh.

After a moment Lune lifted his hoof. Twilight made a soft sound of disappointment as he stopped. Then she felt a warm breath against her most sensitive parts and gasped softly. Lune had lowered his head and was hovering, not quite touching, just over her clit. He turned his muzzle and lapped just next to it, teasing.

Twilight still didn't want any teasing. She wanted him to pleasure her, now, with everything he had. Without even thinking about it she grabbed his head in her magic and turned his muzzle to her clit, putting her hooves to the back of his head as she did so. He let out a surprised little "erk," but made no move to fight her magic. Instead he started lapping at her clit, just as she wanted. She sighed deeply. It felt so very good. He lapped slowly, steadily at her, the pleasure she felt building slowly as he did. Soon she had her head tipped back, panting, her body shuddering as she began to get close.

Lune lifted his head for a moment, perhaps to catch a breath, perhaps to say something, but Twilight didn't even care. She was so very close now! "Don't you dare stop!" she snapped and shoved his head back down with hooves and magic both. She kept her hooves there, on the back of his head, holding him down as he continued to lick at her. Her hips were lifted to his muzzle, her back arched, her body trembling with it, and then finally she came, letting out a breathless cry as once again the pleasure broke over her like a wave.

Panting, she let Lune up, feeling a hint of worry about what she'd done already beginning to worm into her heart. Mostly she was still too busy feeling the pleasure that was slowly beginning to ebb to think much about that though.

Lune, panting, rested his head against her stomach. "Have I pleased you sufficiently, your Highness?" he said.

Twilight froze. "Wh-what?"

"Have I pleased you?" said Lune again, softly.

"Y-you said 'you' and not 'thee.'" Twilight felt something like panic clench around her heat. She had just forced Lune, like in her fantasies. And he had stopped using the archaic language that was a special thing between them. She had gone too far!

"Aye," said Lune, still soft, sounding far too calm. "That is how one speaks to a superior. Forgive me if I presumed. But you seemed to enjoy commanding me."

"I... oh sun and moon, Lune, I am so sorry! I'm so, so, so sorry! I don't know what got into me! I didn't mean to upset y-thee. Please don't be upset with me! I've been having these fantasies, but I didn't really mean it! Honestly! I'm so sorry!"

Lune sat up, shaking his head, looking a bit puzzled. "Twilight... thou hast done nothing to be sorry for. I am not upset with thee. Indeed, I very much enjoy pleasing thee. I think thou hast misapprehended what I meant by calling thee 'your highness', I mean that I am happy to be commanded by thee, to play at being thy servant."

Twilight blinked at him, suddenly feeling very confused. "Play? What do you mean?"

"Ah Twilight... it seems I have misjudged thy innocence. Hast thou not read of such things, that mares and stallions may play at master and servant, or mistress and slave, or many other such fantasies, in the course of lovemaking?"

"Uhm. I've tried to do some research, but the Royal Library doesn't have very much on the subject of sex, other than some clinical texts on sexual pathology. Which I decided to skip. Maybe I shouldn't have?"

"Nay, 'tis not a pathology of which I speak, but a healthy fantasy, between ponies who agree to play thus. 'Tis nothing to be ashamed of, nor afraid of, Twilight."

"That seems... uhm... You mean things like, uh," Twilight flushed as her mind supplied plentiful images from the store she'd been building up all week. "Like imaging another pony all tied up and helpless?"

"Aye. Not imagination alone, though. I have been bound before in the throes of passion." He gave Twilight a broad wink then. "'Tis one of the reasons why I favor this style of bed; it doth provide many convenient places to tie a rope." He gestured at the four-poster around them, a small smile lurking at the corner of his mouth as he did so.

"Oh. Uhm. Really? Uhm. And things like... like bridles and bits? And... and... making ponies beg? And... but... that can't be healthy, can it? It can't be psychologically sound to want to hurt a pony, surely?"

"Pleasure and pain are oft times not far removed from one another, Twilight. But here, I shall prove to thee that such things are common, and little remarked upon by many ponies. Rise, and come with me."

Feeling rather uncertain and more than a little nervous, Twilight got to her hooves and followed Lune back out to his balcony. The sunlight was still bright outside, the sun well past noon, but nowhere near setting yet. It was almost strange to see Lune by daylight—she'd seen him so much more often by night. He looked out over the city below, his eyes scanning the streets. Apparently he found what he was looking for for he nodded and gestured at Twilight. "Come here."

She stood beside him. His horn lit and a moment later they had winked out from the balcony and appeared on one of the city streets below. Lune glanced around, nodded again, and trotted down a smaller side street. It dead-ended in a collection of little shops. Lune went directly to one which had curtains drawn over all its windows and went inside.

Twilight trailed behind, having no idea whatsoever what she would find inside.

She was surprised to find, once her eyes adjusted to the dimmer light, that it was a boutique, superficially not all that different from her friend Rarity's. A closer look around, however, soon had her wide-eyed and very aware that this was not like Carousel Boutique. The dress forms held not dresses nor suits but frilly things she recognized as lingerie, and other things of leather and rubber and metal that she didn't recognize at all.

"Oh my," she said.

"Welcome," came a warm, melodious voice. Twilight turned to find a small, pale purple unicorn with a pink mane smiling at her. "It is an honor to have Prince Lune and Princess Twilight Sparkle visit my humble shop."

"'Tis my pleasure," said Lune, with a small bow. Twilight was still just staring, her eyes wide.

"Although I'm afraid I should say that if you want anything for yourself, Prince Lune, most of what I have here is not to alicorn scale. There isn't much demand for it. Though if you want something for the lovely princess," she nodded at Twilight with a smile, "I may be able to come up with a few things in her size. Otherwise you'll have to custom order."

"I am most likely interested in something fitted to myself, yes," said Lune with a serene nod. "Though I fully understand the necessity of bespoke work. I suspect I may find a few things of use. I should like to see what you have available."

Twilight still felt like her eyes might pop out of her head as she kept scanning the store and finding more and more startling things. A small rack against one wall seemed to hold whips, for Celestia's sake! And at least one of the mannequins was definitely wearing a bit and bridle. She gaped at things straight out of her supposedly freakish fantasies. Things that were common enough, apparently, to be sold in a store right here in Canterlot.

"Well, feel free to browse about. I'll be here if you have any questions," said the mare cheerfully.

"Thank you," replied Lune.

Twilight took a few steps, gazing around the shop again. "How... how did you know about this place?"

Lune grinned. "'Twas Cadance who informed me of it. 'Tis considered the best and most reputable such shop in Canterlot. And quite discreet. The proprietor will not be speaking to the press about our visit."

"That's... good. Very good." Twilight could just picture the headlines now. "Depraved royal sex scandal" would be the least of what the tabloids would probably say.

Lune chuckled. "So thou canst see that here are all the things of thy fantasy, quite common, enjoyed by many, if generally discreetly. Doth this settle thy mind somewhat?"

"Yeah, I guess so," said Twilight. She still felt kind of weird, but Lune was right. If Cadance had recommended the place... Twilight blushed at that. She was not going to think about what Cadance—or her brother!—might have bought here!

Lune smiled. "Now, thou didst say something about bridles?" He nodded at a mannequin, a fairly large stallion-sized one, that had on a harness and bridle set. "I do not think that harness would fit, but I note that the bridle hath an adjustable strap. Perhaps..." He turned to the shopkeeper. "M'lady, might I try this on?"

"Of course. Just give it to me when you're done so I can clean it off if you decide not to buy it."

Lune's horn glowed as he took the bridle off the dummy. Twilight could see that it did indeed have a real bit. She found herself licking her lips. "Here," said Lune, floating it towards her. "Thou mayst enjoy helping me see if it doth fit."

Twilight laughed a little nervously. "Yeah. Maybe." She took it in her magic. Lune lowered his head and she slipped the device over it. It took a moment to get the bit situated correctly and the bridle fastened. It just barely fit on the very last hole. Twilight felt a shiver go through her as she did up the final buckle. It felt too good to be putting it on Lune. She took the reins in her magic and gave them a little tug. Lune's head went down further, quite obediently. That felt far too good.

"Dost thou," said Lune, his head still down and his voice sounding a little odd and muffled with the bit in his mouth, "like me thus?"

Twilight licked her lips again. "Maybe a little too much," she said, feeling flushed. She nearly wanted to jump on Lune and do something indecent right there.

Lune chuckled. "I shall definitely be purchasing this particular item, then."

"Hoo boy," said Twilight.

It was something like an hour later when they left the shop, Lune having bought quite an assortment of items, and also having been thoroughly measured so that several more could be custom made for him. He winked directly from the shop's doorway back to his rooms, somewhat to Twilight's relief.

Once there, Lune started unpacking a few of his parcels. He seemed very pleased with himself. Twilight still felt odd. It wasn't that she didn't believe Lune about all this being okay, exactly, but she just couldn't quite get her emotions to line up and listen; they were going off in a dozen different directions, from interest and arousal to abhorrence and worry.

Lune set aside most of what he'd gotten and picked up a riding crop. "If thou dost not object, I could begin by teaching thee how to use this?"

"I... I guess so. But... I mean, I'm going to hurt thee. Are... art thou really certain that it's okay?"

"Twilight..." Lune put the crop down and came over to her. He folded forelegs and wings both around her, holding her. Twilight sighed and leaned into the embrace. "Tell me, Twilight, am I Nightmare Moon?" asked Lune.

Twilight frowned, puzzled, but answered, "Of course not."

"Yet I do play at being her each Nightmare Night. Even this last, after I had become Lune. 'Twas thou who encouraged me to do so. Dost thou remember?"

"Yes. Because I realized that sometimes ponies enjoy being scared."

"Just so. And just so do some ponies enjoy being hurt, and restrained, and treated in ways that might seem demeaning or harmful. Thou wilt be no more evil, if thou shouldst strike me tonight, than I am evil for frightening foals on Nightmare Night."

"I... I see." She did, suddenly. Put like that, it made sense. She felt the sick weight of worry suddenly lift from her heart, leaving interest and curiosity to fill her. "Well, then..." Twilight stepped from Lune's embrace, towards the bed. She looked down at where Lune had set the crop down. She smiled broadly and picked it up in her magic. "I believe my servant was about to teach me how to use this?"

"Yes your Highness," said Lune with an answering smile. For a moment they just looked at each other, both thinking pleasant thoughts about what was to come. Then Lune cleared his throat. "The crop is relatively easy and safe for a beginner. Nevertheless one should strive always for control and precision. 'Tis intended that one should strike with the broader tip, for both safety and a satisfying sound and sensation. One should not strike so that the rod touches one's target. If one should strike over bone, 'tis most painful, and if used with overmuch force may cause some damage. Strike lightly when in doubt. The more fleshy parts of the body are most safe, and one may use great force on the flanks in particular. If one begins softly and works up slowly, one can strike much more strongly than otherwise. I shall not hesitate to inform you, Highness, should you strike me over-hard. Yet first you should try the feel of it on yourself, against a foreleg lightly, perhaps, to become accustomed to the heft of it, and the control needed."

Twilight nodded. She tapped the end of the crop lightly against her upper leg. She hardly felt the light slapping sensation through her hide, so she tried it somewhat more firmly, then let out a little yelp. It had stung a bit. She looked over at Lune, who was grinning a bit too much. She stuck out her tongue at him. "You are far too impudent for a servant! Maybe I should put the bit back on you?"

Lune flushed. "Uh..."

Twilight giggled. "I think I will. Stay there!"

She rummaged in the little heap of packages from the shop until she found the bit and bridle. When she carried it back over to Lune, he lowered his head obediently without being asked. Twilight felt a pleasant little shiver as she slipped it over his ears and fastened it behind his head. She pulled on the reins, making Lune follow her over to the bed, where she wrapped them around one bed post. She could hear, as she tied the reins off, that Lune was breathing a little faster.

Her own breath was coming fast and her heart was racing in nervous anticipation as she lifted the crop in her magic again. She slapped it against Lune's flank lightly, hitting the moon on his cutie mark. He drew in a breath as she hit him, but did not cry out. Remembering what he'd said about starting softly and working up, she began a series of light taps, switching occasionally from one flank to the other.

She could hear him breathing rapidly, and he twitched a bit whenever she hit slightly harder. She decided to try to get him to make some more noise. She gave him a good, solid whack and he flinched, letting out a whinnying cry and jerking against the bridle.

"That wasn't too much?" she asked. He just shook his head. "Oh good. In that case..." She hit him again, just as hard, on the other flank. He twitched again, though he didn't whinny this time. She grinned and kept going, mixing softer flicks with harder blows, ramping it up slowly, until finally Lune started crying out with each one, panting hard, pulling against the bridle that held him in place. His tail flicked and swished around at times, and Twilight could see that what she was doing was having a certain effect on him. His stallionhood had emerged and was hanging, stiff and ready, below his barrel.

Feeling extremely daring, she suddenly slipped the crop under him and tapped against Lune's cock with the lightest of possible taps. Lune gasped and froze in place. As she continued the gentle slaps he moaned. Twilight definitely wanted to hear more of that sound. She considered how best to go about it, and came to a simple conclusion. She wrapped her magic around his cock, a warm magenta band, and squeezed it. He moaned again. Then she hit his flank, as hard as any strike she'd given him so far. He cried out, a gasping, completely involuntary sound.

She grinned. This was amazing. She could make him react however she wanted. She started to stroke his cock with her magic, slowly, gently, while also hitting him, first on one flank, then on the other. He cried out with each blow, and rocked in time with her strokes, his eyes tightly shut, pulling against the bridle as he moaned and tossed his head. She squeezed her magic tighter, pumping his cock faster even as she hit him even harder than she had before. He nearly screamed, jerking on the bridle hard.

Suddenly she let go of him with her magic. She started tapping the crop softly again, just a reminder that it was there. Lune shuddered, his head dropping, no longer pulling against the reins, his breath coming in heaving gasps. His legs were splayed, as if his knees were having trouble supporting him. He was trembling all over and his cock was twitching under him. "How am I doing, my servant?" asked Twilight, wanting to giggle at the wonderful, powerful feeling of euphoria that came from having had such an intense effect on him.

"Ah... moon and stars, Highness... you are all too gifted at such evil..." His breathless voice still sounded rather odd around the bit.

Twilight did giggle at that. "Should I stop then?"

"Stars no! Please!"

"Please?"

"Please, Highness. I beg of you, don't stop."

"Hmm. I think you need to convince me." Twilight's magic undid the reins from the bedpost and tugged on them, pulling Lune around to face her. She held out one front hoof to him. He didn't need any further clue, he dropped to his knees in front of her, his rump still raised, and bent his head to kiss her hoof.

"Please Highness," he said, his tone earnest, pleading. Twilight looked at him. With his head down and his rump up like that she still had quite a good view of where to hit him with the crop. She put her hoof on the reins, pinning him in that position, and started slapping his flanks harder again. She had to feel her way under him with her magic, sliding it along his barrel until she found his cock again, but that wasn't difficult. Lune moaned as soon as she touched it. Then he cried out as she hit him harder. She ramped up both sensations, stroking his cock faster even as she hit him harder and harder. He was soon crying out again, pulling instinctively against the reins, so that she had to split her concentration even further to use magic to hold them down. It was getting difficult, doing three completely different things, but at least just pushing force against the floor to keep him pinned wasn't mentally taxing. The results were worth it in any case. Lune's hindquarters were jerking and bobbing, flinching from her blows even as he tried to thrust into her strokes. His whole body was shuddering, his sides heaving as he panted. He cried out again and again, seemingly beyond words now.

She hit him suddenly as hard as she dared, one resounding strike on each flank, garnering two of those involuntary cries that were almost screams, and then she let the crop fall, just stroking his stallionhood, seeing how his body shuddered in front of her, his breath short and ragged, his hips jerking uncontrollably. She pumped his cock faster, and with a sudden groan he came hard. She cupped her magic around the tip of his cock, feeling it twitch and spurt, cum spraying out into her magic in a startlingly large volume.

When he was done he gave one last shudder, then simply collapsed completely, his hind legs sliding out from under him until he was lying flat on the floor.

Twilight lifted her hoof from his reins, but he didn't lift his head, he just lay there, panting. Twilight settled herself on the floor next to him, glad of the deep carpeting. She stroked his mane, running her hoof through the gossamer strands which were hanging nearly limp now, feeling the faint tingle of the starry nimbus that clung to them. After some time, Lune slowly opened his eyes and looked up at her. "Mmm," he said dazedly. "That... Thou... 'twas... so... mmm..."

Twilight giggled. "I take it that means thou dost approve?"

"Yes indeed.".

"I'm glad," said Twilight. "I enjoyed that a great deal." She wanted to cuddle up with him now, even though it was really too early for a nap. He was still sprawled on the carpet, completely limp, which couldn't really be comfortable. She smiled and picked him up bodily with her magic. She deposited him on the bed, then climbed in next to him. When she snuggled up beside him he immediately wrapped his hooves around her with a sigh.

The feeling of a strap tucked rather awkwardly against her head reminded her that he still had the bridle on. "Is the bridle uncomfortable? Should I take it off?"

"'Tis fine for now," said Lune, still sounding rather blissfully dazed. Twilight chuckled. She turned and gave him a soft kiss. He kissed back, parting his lips in invitation. She kissed a bit harder, slipping her tongue between his willing lips. She felt the hard touch of the bit against her tongue as it pushed over his and shivered. She didn't know exactly why that particular item appealed to her so much, but she really did like Lune in it.

"You know, I'm not really tired yet," she said after she'd broken off the kiss.

Lune chuckled. "Nor am I. And we have several other toys for thee to try on me."

"Very true. If thou dost not mind, anyway."

"Nay. I shall be very sore tomorrow, I am sure. But it shall be more than worth it." He gave her a wink. "Anything to please my Princess."

Twilight giggled. "Such a good, faithful servant. Well, let's see what else thou canst teach me to use."

"As you desire, your Highness."
