Shining Armor likes being bound, but the problem in paradise is that Cadance just can't get into doing the binding. A nerdy mare is just the pony for the job!

Spoiler: This is a fic where Shining Armor and Twilight Sparkle end up in what would be considered sexual situations. I will leave it up to readers to determine if what they have together is incest, but I will make it clear that no sexual intercourse happens in this story.

To Be Held

Shining Armor rode the train to Ponyville in an introspective mood. He tried to remember how this had started, how his escape had been formed. Of course, it had been an accident. A stallion doesn't go to their sister and ask her to tie him up—to do things to him.

Smiling out at the window, memories came tumbling back that made Shining's heart swell. They were happy memories. They were memories of time spent with his wife, and time spent with his little sister. It had only taken one incident to have them spawn this new part of his life.

His body stirring just at the memory, Shining Armor blinked a moment too long, and the echoes of that time rushed back into him.

Sombra was defeated, the Crystal Empire had praised what they called their crystal princess, and the party had wound down. Shining Armor had spent a giggly hour with his wife explaining that he liked being tied up—sometimes. That he liked restraint, and a strong mare.

Alcohol had been involved.

"When I agreed to this, Shiny, I didn't expect it to be so hard," Princess Mi Amore Cadenza, or Cadance, said. "Would you stop kicking that leg?"

Shining kicked the badly bound leg. "But Cady, you're supposed to tie the rope so I can't get out of it." He kicked again, this time proving how bad an idea tying his back legs to their bed was. The crack of timber rang out, and Shining almost collapsed to the floor as the bed's frame broke like so much timber under a strong stallion's kick.

Frowning at her intoxicated husband (and still riding a high of a night spent reveling and quaffing) Cadance stomped over to him and used her magic to bind Shining's legs together—all of them. "Oh. I'll tie you up alright! Come here, Shining Armor, and I'm going to—"

The sound of the door opening—despite the soundest of locks—broke the mood for Shining and Cadance. They tilted their heads up at the same time to see a purple unicorn poke her head in.

"Sh-Shining?" Twilight's shock at seeing her bound brother turned quickly to panic. Energizing her horn, she sent a blast of energy at the ropes. "Don't worry! I'll save you! You won't get away with this—uh—Chrysalis?"

"Twily! Wait!" Shining was almost buried under a pile of shredded and exploded rope. He kicked his legs, sobering a little at the shock of his little sister barging in on him and his wife snuggling, he tried to call out again just as Twilight loosed a stun-bolt at Cadance. "Stop!"

Cadance hadn't tried to block the bolt. Her sister-in-law was as powerful a unicorn as could challenge an alicorn in a fight, and Cadance didn't want to see where that would leave her. Using her magic as quickly as she could, all she did was boost her resistance to the spell.

The bolt crashed into Cadance, sizzling purple lightning chased all over her, and the Princess of Love's eyes rolled up into her head, and she became a slumping pile of alicorn. Her thoughts scattered, Cadance struggled against the stinging that, despite her resistance, had completely disabled her.

"There! Now her disguise should drop, and we'll see—" Twilight blinked a few times as the magic failed to reveal the stunned changeling she expected to be Cadance. "Any second now… Look! Green!"

"Twilight! STOP!" Shining Armor was a soldier, and possessed a firmness of voice at volume to get through to even the thickest-headed recruit. Right now, his sister's head was full of all the wrong things, so he used his parade-ground voice.

It worked.

"Oh good, you're awake. I was worried she'd used that crazy mind-control stuff again. Help me tie her up!" Twilight said.

The request tickled a funny bone in Shining Armor that, despite the irony, he didn't let color his response. "Twily, this is Cadance."

"No. That's a changeling. Why else would she be tying you up?" Twilight asked.

And there Shining Armor had the decision of a lifetime to make. He shook the burned and destroyed pieces of rope from his legs and stood up. "Sorry, Cady, it's been a great marriage, but I can't tell—"

Shaking the last of the magical stunbolt off, Cadance looked over at her soon-to-be-ex-husband, and glared at him. "Shining Armor! You are going to tell Twilight the truth right now!"

"What's Chrysalis saying? What truth?" Twilight's head resembled the umpire's at a tennis game—swinging back and forth between Shining and "Chrysalis".

"Tell her, now." Cadance didn't shout, she put ice into the last word that would last her husband almost fifty years of marriage unless he 'fessed up, however.

"ItoldCadanceIlikebeingtiedup."

The first thing that came to Twilight Sparkle's head was that she didn't understand the words. The second thing was a modified time-travel spell that would let her not only go back in time, but also listen to the words super slowly. But she'd grown as a pony since the days when she'd spontaneously cast time travel spells. "What?"

Cadance waited a moment, but when Shining didn't repeat the words at a slower pace, she leveled a stare at him. She wasn't an expert at staring, but after her wedding she'd spoken to one of Twilight's friends about it, and had picked up a few pointers from a master.

"We both got a little tipsy, and I told Cady I'd like to try being tied up. There." It wasn't complete shame that flooded Shining Armor's existence, there was a healthy mix of embarrassment in there too.

The reality of the situation didn't actually register for Twilight Sparkle—her brain didn't work like that. "What knots did she use?"

"What?" Cadance asked, and almost immediately regretted it.

"Well, if you use the wrong knots, not only could you hurt him, but he could struggle free. Do you have some rope?" Twilight asked.

Shining Armor sat in stunned amazement as his wife passed his little sister a second length of rope (that hadn't partaken the same fate as the first). Purple light flared brightly around Twilight's horn, and Shining had the impression, from the suddenly animate rope, of a snake about to strike.

"Here. Let me demonstrate." Twilight Sparkle had read every book that she considered worth reading. That hadn't taken her too long. Then, in the Royal Canterlot Library, she had attacked the less interesting books. She wasn't a master at all the crafts she'd read about, but there had been two particular topics that had interested her greatly once she'd investigated them: the mathematics of knots, and tying knots.

When Twilight Sparkle had investigated the remaining books, she'd found a particular aisle of the library that fillies and colts weren't allowed in. The topics were not all to her liking, but there were books about knots and about tying ropes.

The end of the rope snaked around Shining's back leg—the one Cadance had failed to secure—and wound itself into a knot. It pulled upward, did a quick loop around his body, and then lashed out to grab his other back leg.

Speechlessness was one symptom of being tied up by his little sister, the other—to Shining Armor's absolute shock—was arousal. She wasn't soft about using the rope. When it caught his forelegs, Shining actually tried to struggle, but Twilight's magic was beyond his physical ability to withstand. Bit by bit, strand by strand, he was immobilized by the rope and even felt a length of it loop around his neck and tighten just enough so that he knew she had him completely, then it charged down his back.

Twilight used her own magic to yank her brother's tail up, wove the rope around and through the plume, then tied it off. She was out of rope, but there was one part of him still unrestrained. With the focus and complete disregard for propriety that Twilight Sparkle displayed on a near hourly basis, she used her magic to wrap her brother's penis up and secured the power around the base of his balls. The spell was simple to tie off, and afforded Shining Armor some modesty.

"Just, like, that!" Twilight Sparkle said.

Cadance watched as Twilight marched for the door, tried to work the handle (that Twilight had apparently broken on her way in), and finally teleported outside. She turned her head back to her restrained husband. "Wow."

"C-C-Cady? Uh…" Shining had no more words. He was bound as tightly as he'd always imagined—in his wildest fantasies—and it was everything he'd wanted. He squirmed, shifted, bucked, and kicked. No matter what he did, however, Shining Armor could not break free of the ropes.

A flash of purple light was heralded by a loud *POMF*, and Twilight stared at Shining Armor. "I'm so, so sorry! I didn't mean to just—" She stopped as Cadance walked toward her. "I really didn't! I just get carried away sometimes, and then I just do things without thinking, and then I—"

"Twilight Sparkle," Cadance said. "Twilight? It's okay. Come and talk a little bit, sister to sister."

Shining bucked his hips as best he could, the motion tugging sharply at his restrained tail. The worst part about the thing she'd put on his shaft was that when he moved, it only moved a little. It wasn't enough to get him off, but the slightest twitch made it move just a little. It was torture. It was wonderful.

"I'm no good at this, Twilight." Cadance made sure the door was closed behind her before talking. "He wants me to do this, and I tried, but my heart isn't in it."

"H-H-He really likes it?" It was all Twilight could think to ask.

A loud moan interrupted their conversation. In the previous room, Shining was writhing in frustration and need—not that either mare saw that.

"I think that's a yes." A smile broke out on Cadance's lips. "I'm not asking you to do other things with him. But if you would just do this? This is something I can't do for him. I just can't."

"Just tying up?" Twilight asked. "I can't believe I'm contemplating this. He's my brother!"

"Which is why I trust you, Twilight Sparkle."

Biting her lip, Twilight remembered back to what she'd done to her brother, and could already imagine improvements—changes. She was just about to say she'd think about it, when her brother made the happiest sound she'd ever heard him make in his life.

A trickle of pride, of accomplishment, colored Twilight Sparkle's thoughts. She closed her eyes for a moment and imagined her big brother squirming and writhing, and a little smile worked its way onto her face. "He sounds happy."

"I've heard him happier, but this is a different happy. This is relief happy. Just try it, if you don't like it, or he doesn't like it, I…" Cadance tried to think as she trailed off. "… I'll find somepony else. Somepony who doesn't know him like you do."

Shining's cries seemed to taper off. Twilight reached out with her magic and just twitched the grip of the sheath around his shaft. A fresh cry of bliss and need rang out.

Something wild was free in Twilight. Something that almost felt dangerous. She opened her mouth to agree, but then used her magic to twitch her brother's shaft again. His cry of pleasure sent a tingle along her spine that Twilight couldn't begin to comprehend.

Cadance saw the look, and she sensed Twilight's magic. She could taste a lust rise in her sister-in-law that had nothing to do with actual sex. "We have a deal?"

Twilight waited for the moans to stop, to drop back into silence (through the wall at least), then she tweaked him again. Fire was burning in Twilight, and she wanted more. "Yes." There was no trace of softness or reluctance in Twilight Sparkle's voice.

When Shining Armor looked up at the sound of hoofsteps nearing him, he saw Twilight looked down her nose at him. His lust was overwhelming, and he'd spent nearly all the time both mares were away bucking his hips for all he was worth. He was tired, horny, and something told him this mare was his tormentor.

"Cadance told me everything, Shiny." Twilight leaned down and kissed her brother on the forehead, just below his horn. "I didn't mean to tease you like this. To dangle something you wanted so much before you. I just—"

Shining opened his mouth to tell Twilight it was okay when his shaft was squeezed again. All his restraint was lost, and Shining Armor, Prince of the Crystal Empire, humped weakly at the air mindlessly.

"I just worked out something about me. I like control." Twilight Sparkle waited for her brother to stop humping as stare at her in disbelieving shock before she tweaked his shaft again, sending him back into mindless lust.

"You're really good at that." Cadance had already felt the little bond form between Twilight and her brother. It was nothing like the existing bond of love, but it wasn't a bad thing. She watched as Twilight used magic to strum Shining to the edge and let him dangle again and again.

Finally, Twilight couldn't take it anymore. She cleared her throat. "I need to go back to my room. You might not want to untie him until morning. He might—uh—be a little worked up."

Licking her lips, Cadance looked down at her husband. Shining was panting and snorting like a beast. "I look forward to it. Thank you, Twilight."

Realizing where Cadance's mind was headed, Twilight opted to teleport all the way back to her room directly. The moment she was out of their presence, her magic formed into a long rod and shoved into her. "Fffff—" Her climax was almost as fast to hit her as Shining's wound up being.

Nothing would be left to chance. Twilight Sparkle was not the type of pony to approach any problem without careful planning (so long as there was time to plan), so ever since that first time she'd taken away her brother's freedom—when Cadance had asked her to do it again—Twilight Sparkle had planned for it to happen again.

At first had been study. To do a job properly, one must understand every aspect of it. Books had been sought, and even experts contacted (there was a shop proprietor in Canterlot who had been most helpful), all with the sole aim of understanding both sides of this problem.

Ropes were the beginning. They were a gateway and an old friend, as one pony had described them, but they were not a mainstay. As much as ropes were nice, Spicy Hot had explained to Twilight, most ponies would want more—different.

"Are you comfortable?" Twilight asked.

The second stage had involved taking her data and building hypotheses. Her brother liked being bound, restrained, and played with. This was a fact—it was the core fact of Twilight's study. She looked to her diagram on the chalk-board again.

Restraint meant control by another. Binding represented a visceral display of that power and control. Being toyed with was proof that, beyond the binding there was something more.

"Eeyup."

"You can't move?" Twilight asked.

"Nnope."

A subject had needed to be recruited. Twilight had, early in her research (and at Spicy Hot's suggestion) decided that self-bondage—while completely possible—was dangerous.

Her eyes ran over Big Mac, and Twilight smiled. The bindings in this case were a mix of metal clamps/cuffs and magic. It was her best design yet, and if it could restrain McIntosh Apple, then she hoped it would work with her brother.

They were in the basement of the Golden Oak Library. Twilight had used her magic to extend her basement into a new room, and had wrapped it with enchantments to keep sound out—and in. She walked around McIntosh, circling him and examining the magical enchantment in the pieces of metal.

Reshaping: they would conform to their wearer.

Safe: the metal could not pierce the flesh of a pony.

Secure: the amount of creatures that could break the metal itself was a short list.

Magical: as each piece was attached to a pony, it would magically link up with those around it.

Timed: the magic of the bindings would relent after one full day.

She had made three sets. One was fitted to McIntosh, the other was safely locked away, and the third had been a friendly payment to Spicy Hot. Though she worried about the advances of Spicy Hot, the bat pony had never proved to be anything but a gentlepony when things had turned serious, and Twilight appreciated that he was serious about safety.

"Are you ready for the last bit?" Twilight asked.

"Nnope!"

Triggering the release, Twilight Sparkle released all the bindings on Big Mac.

Gasping, McIntosh shivered all over as his body became his own again. This was all experimentation, which he could understand, but he wasn't ready for Twilight's grand experiment's last phase. "Th-Thanks!"

"No, Big Mac. Thank you. This will all help with my research." Twilight had to use her hooves to help McIntosh remove the binding pieces—they were magic resistant.

The truth was, when Twilight Sparkle had invited McIntosh to experiment, he'd thought she meant "experiment". He had a bit of a reputation around town, and he lived up to it. He wasn't looking for a relationship—he was just after some fun times with mares.

McIntosh Apple had failed to fully gauge what fun time meant to Twilight Sparkle, but after his afternoons with Fluttershy had come to an end recently, he'd jumped at the chance to be with a pretty unicorn. Despite that he hadn't been sure why she wanted to hook up, McIntosh had managed to get a little fun out of the situations, but her further ideas were a bit too far for him.

At the end of the day, McIntosh had no real interest in the being-tied-up thing, and honestly wished Twilight would get his hints about coffee, and stop just bringing him drinks. Despite his frustration, though, McIntosh kept coming back in the hope she would forego the binding stuff and just present to him. He sighed. "Same time tomorrow?"

"No. I'll be busy for the next few days." Twilight Sparkle finished stacking the pieces of metal aside and turned back to McIntosh. Leaning up (it was a long way for any mare to reach Big Mac's face), she put a chaste kiss on his cheek. "Thank you, McIntosh."

For nearly six heartbeats McIntosh Apple considered jumping on Twilight Sparkle. It was a wild plan that contained the hopes and dreams of a stallion, but he shoved it out of his mind. Thick as he knew Twilight could be at times, he finally got the impression that she simply wasn't interested in sex. Or at least sex with him.

Leaving Twilight without saying another word, McIntosh cast his thoughts around to the various mares in town who liked to share their bed occasionally. His mood instantly boosted, he began to trot out of the library.

Twilight Sparkle sighed. The binding and restraint system she'd designed was the crowning glory of her research so far. She looked over the pile of equipment and let out a sigh. Big Mac had never given her permission to test the extra devices she'd come up with, which was a problem. She wanted all her equipment to enjoy the same development cycle her restraints had, but McIntosh just wasn't willing to help.

Staring helplessly at the first device, Twilight Sparkle racked her brains for an idea to get around the problem. Shining Armor was due to arrive in another day, and she had no idea if her equipment would even work.

Spicy Hot had happily sold her toys, and from those Twilight was sure the devices she'd made would fit, but there was a difference between fitting and working.

A knock at the front door of the library upstairs surprised Twilight—shocked her out of her contemplation of the conundrums of penis control. Walking through the open door, she took the stairs two at a time, and made sure to close and lock the door at the top of the stairs before approaching the front door of the library.

As the door opened, Shining Armor could see the target of brotherly (and other, now) affections standing inside. Panic filled him when she didn't reply immediately. He had no idea what the protocol was here. Would she send ropes after him immediately? Would she wait for a special keyword he had no idea about?

"BBBFF!" Twilight's emotions warred within her, so she did what she usually did—picked out the best one and shoved the rest into the background. Hugging her brother, she felt his initial stiffness fade as he reached a foreleg around her withers.

"Hey, Twily! How are you?" The words were mundane, normal. It helped Shining Armor anchor himself in the now and not what-will-come. He hugged his sister for the usual length of time, then followed her inside the library.

"Oh, you know, same stuff as usual—arranging books, saving Equestria from monsters, planning ways to secure my brother so he can't move." Twilight Sparkle froze for a second. The level of awkward in the room began a rapid ascent. If there was a gauge that could measure uncomfortable silence, it would need to have a logarithmic scale.

Shining winced at how panicked his sister looked. "Like what?" he asked, quick to break the silence before it grew to the point where all of Equestria would be drowned in awkward quiet.

The words were a joy to Twilight's ears. She perked up immediately. "Well, at first I tried cuffs, but cuffs aren't enough to fully restrain. I was really confused over what to try next, but then I found out about other ponies that like this. Then I asked one about how to really bind a pony up, and he—"

"Twily!" Shining Armor was caught between arousal and humor. When his words cut Twilight's verbal diarrhea short, he was left searching for the conversation again. "It's alright. I trust that you researched this more than anypony else could. Before we get into it, though, I have some things for you."

Twilight took the scroll her brother offered first. There were many ways to give Twilight Sparkle things, but if you gave her anything containing words, you had to expect her to read whatever it was before taking her next breath.

Dear Twilight Sparkle,

Thank you. I needed to say that first. Thank you for being there for him and for me. You have my consent to help with anything Shiny needs. You feel more like a sister now than ever.

We should have a day together, soon. If nothing else, I want to hear your thoughts on your time with Shining.

Mi Amore Cadenza
Cadance

Taking a breath, Twilight Sparkle put down the thankfully short scroll only to find two wrapped items thrust toward her. "More things? Presents?"

Shining chuckled as Twilight immediately shook the first box by her ear. "It's candy. I wanted something I knew you'd enjoy. The other one is from Cady."

Twilight could appreciate a good distraction as much as the next pony, but she was also excited to test the devices she was unsure of, and there was the part of her that wanted to hear her brother cry out. She unwrapped the gift from Cadance, only to find a paddle inside.

Having visited Spicy Hot's shop several times, Twilight knew a spanking paddle when she saw one (part of her time spent in the shop had been to catalog everything). She levitated it out and looked at Shining Armor. "Cadance's present is more useful right now."

"T-T-T—" Shining Armor's eyes focused to pinpricks. His little sister's demeanor had changed completely. Gone was the nerdy sibling he'd known all her life. Here was a mare who knew what she wanted.

Twilight shook her head slowly. "Only call me Mistress T." She'd hoped she could say that with a straight face, but a giggle got free without her realizing it. "I can't do that. All that masters and mistresses stuff is just…"

The steely-eyed mare was Shining's sister still. He relaxed. "It's okay, Twily. I don't think I really want that kinda stuff. Why don't we just have some fun?"

"Come on. I've made the coolest stuff ever, and I need your help testing some of it." Relieved she didn't need to do the rubber-clad-mistress thing, Twilight Sparkle unlocked the door to the basement stairs and descended.

The joking around, the chatting with his little sister, it all became real as Shining Armor stepped into the stairwell. The moment his tail cleared the door it swung shut and locked. It was a precaution, he knew, but it still made his heart beat a little faster.

"I built an add-on, just for—well—this." Twilight reached the bottom of the stairs and kept walking. She had planned this moment for so long. Twilight had played through the various ways this could go until she'd settled on ambush.

Walking into the second room revealed closets around the walls, and a pile of metal in the corner. Shining watched Twilight walk over to it, but didn't see what she did until a piece of the metal was hurtling through the air toward him.

The first thing Shining Armor did was try to grab the metal. His horn illuminated pink, and a line of magic extended toward the metal. When the metal slipped through his magic like water through a colander, he felt panic rise.

Metal impacted with Shining's face, and he felt the stuff ripple and flow around his features. It extended all the way from above his eyes, down the front of his face and to the tip of his nose. Gripping under his jaw, Shining Armor felt suddenly restricted and encased in the headgear. "Twily? What's this?"

"Close the door, Shining," Twilight said.

Charging his horn with magic felt to Shining like he had crystals in it again, although there was no pain. His magic fizzed and spluttered, and barely anything got to his horn. Reaching out to the door almost had him sweating, actually closing it had him panting. The click from the door was not just mechanical, but magical—a silence barrier locking into place as sure as the pall of the door's lock did.

Panting, looking through the eyeholes of the metal face guard, Shining watched as Twilight weighed up a pair of leg-guards. Only they weren't leg-guards. Shining Armor knew his namesake very well, and while the pieces superficially looked like armor, he could see they only appeared to be designed to cover muscle masses.

"What's wrong with my magic?" Shining asked.

"Part of the equipment is that it suppresses magic. Not completely, you can make simple things happen." Twilight, holding the leg restraints with her hoof, tossed them forward casually.

Like with the first piece, Shining tried to put up a defense against the equipment. This time, however, his cutie mark burned with power as he formed a shield around himself. Thanks to the weakening effect of the headgear, however, he barely made something that would stop a foal—it certainly didn't stop two magic-resistant and animated restraints.

The moment the metal connected with his legs, Shining Armor felt it wrap around and encase the limbs. He looked down and lifted one hoof up to inspect it. "W-What is this stuff, Twilight? And why haven't you given the design to the Royal Guard?"

"Armor that attaches itself? I guess that could work. It would need a better way to remove it than how this is—oh!" Twilight exclaimed when the rest of the restraints—sensing the few pieces already bonded to a host—launched themselves toward Shining Armor.

The wave of metal struck Shining, but it didn't shove him back. It wrapped around his barrel, locked over his haunches, and even latched around his lower back legs and dock. The last piece to reach him clamped around his neck and flowed to lock in place like a huge collar. "Twilight, how is—"

Shining's eyes widened. His back legs folded themselves, and magic snapped them down so that they were loosely locked to his body. His dock was lifted, raised high and held there. "Twilight!"

"It's securing you, BBBFF." Twilight made sure to enunciate each letter slowly. She watched as her brother's limbs were secured to his torso, his neck forced to bend down, and his face locked against his barrel. "Squirm, Shining Armor. Fight it."

Wasting only a few panted breaths, Shining Armor struggled against the trap his sister had built. He started by kicking his back legs. He lashed out for all his worth and his legs got almost to full extension before the bindings pulled them back. Trying again, he kicked, and this time there was more restriction. Lashing out with all his limbs, Shining struggled for what felt like hours before he couldn't move his legs anymore.

Tired, but not so much as it should stop him, Shining tried again to squirm and break free, but now the rubbery binding action was too much. Straining to lift his head, all Shining could see was a pair of purple legs directly in front of him. Even with the ropes on he hadn't felt this weak. He could have used his magic that time, but now he was completely restrained at the hooves of Twilight.

"Can you use your magic still?" Twilight asked.

Obedient so far as he hoped for more to come, Shining struggled against the magic-dimming effect and got a small burst of pink free, but nothing more.

"Good. Do that and I'll stop, okay?"

Shining couldn't nod, so instead he opened his mouth. "Oka—"

Something shoved into Shining Armor's mouth. He tried to shove it back out with his tongue, but realized too late that it was a long shape. His eyes bulged a little as the implication dawned on him.

"Sorry about the shape, but I got the first thing that would fit in well, and—uh—this was it," Twilight said.

Shifting his tongue around in his mouth, Shining focused his attention on the shape. Sure enough, Shining Armor could feel the medial ring of the toy, and when he flexed his throat muscles he could even feel the flare of it. It was embarrassing and amazing at the same time.

"Now that I've got your full attention, BBBFF, I have a confession. There's five different penis devices I needed to test, but I couldn't get anypony to agree. Would you like to test them for me?" Twilight waited five seconds. "Great! I'll get the first one!"

The enthusiasm in Twilight's voice made Shining's ears perk forward. Unable to see what his sister was doing, Shining tried desperately to think on what kind of devices she'd make for him. His focus was broken by a big, floppy, purple thing hanging in front of his vision. It looked like some kind of grub, and it was moving.

"This is the stallion-teaser mark one. Do you want to test it?" Again, Twilight waited a few moments. "Great! Now this one actually feeds on your—ahem—semen. I think you can have it on for an hour before you'll need some fluids. Are you ready?"

The thing was gone from Shining's sight only a moment before it touched his hard shaft. His eyes widened, and ears tucked back as it pulled itself onto his flared shaft. The aching emptiness was replaced, bit by bit, by the magically animated sheath. Shining tried to shake his head, to squirm, or show any sign that he was living out a dream he never knew he'd had.

As the animated sheath pulled itself down his shaft, Shining felt it undulating, massaging him constantly. All his attention was on his stallionhood, such that the spring that'd been winding up inside only needed a little more before he knew he'd explode.

The motion was mindbogglingly slow. He wanted it to speed up, but his wants counted for naught when he was bound so perfectly. His medial ring was kissed by the lips of the device, and as it crept forward over the most sensitive part of him, Shining's whole world turned to mush.

Sucking on the shaft in his mouth, Shining managed to stretch the restraints' binding him just a little before they snapped back against him again. Ever more firmly restrained, he could think of nothing except for the thunderous clenching muscles that fired his fertile seed into the toy.

Sensitive, Shining felt when the sheath advanced further. The next undulation caused his mind to unravel and his thoughts to scatter. Whining into his gag, Shining Armor let go of all his responsibilities and cares and simply existed to be milked by the animated sheath.

Twilight's ears might as well have been filed with gooey caramel. The sounds her brother made started her motor and made her purr. She watched as her little artificial parasite reached the bottom of his penis and set to work milking him properly. Each movement it made stirred another whimper from Shining's mouth, and each whimper made Twilight hornier and hornier.

"Excuse me, BBBFF. I need some Twilight-time," Twilight said into Shining's ear.

Shining Armor's second climax was better than the first, and the third was better than that. His mind was reduced to a simple machine that could only compare the intensity of his release, though that was the only "release" he wanted.

The hour had been eventful for Twilight Sparkle. She'd never heard her brother moan, groan, whimper, and sigh so much before—and it had her body hot. Sitting across the room and out of Shining's sight, she rubbed her vulva with slow strokes as Shining reached another climax.

It had been a slow burn for her, not the rocket-ride her first time binding him had been. Nonetheless, so much masturbation did build her to her own release—several times. She was slowly stroking now, though, with no aim for anything but slow enjoyment.

A buzzing sound cut through the soft sounds of pony enjoyment. "Oh, I think you're done!"

Shining's reality—that of a bound pony forced to feel pleasure again and again—collapsed when the thing on his penis pulled free, and when the binding magic of the metal he wore let go. Dazed, confused, he swung his head around to search for his savior.

Twilight Sparkle, Shining Armor's little sister, stood over him. He looked up at her and made mewling sounds around the penis-gag he wore.

"Oh right. Give me a second," Twilight said.

With his mouth freed, Shining felt somehow empty, and with his shaft still rock hard and exposed to the air, he was needy. Craning his head up, he could see and smell Twilight—and she smelled good. The wild animal inside everypony, the beast that would help them flee from danger, or stand and fight, urged Shining to his hooves.

But, Shining Armor had long-since learned to control the wild pony that lived within. Guard training kicked in, and he jerked from the daze his body had insisted he endure. "T-Twily?"

"Open wide," Twilight said.

Shining didn't hesitate. He opened his mouth, now trusting his sister more than anypony in his life except Cadance. Of course, he closed his eyes too—Shining was learning to like his sister's surprises.

Something new pushed into Shining's mouth. Thick, but not as thick as the rubber dong had been, it felt infinitely more squishy. Experimentally, he sucked on the shape. Cool water, sugary and amazing. He opened his eyes to look, and found a tube running to a water tank on a stand beside him, and there was the tube connecting the tank to whatever was in his mouth. When the fluid trailed off, he suckled again, and once more was rewarded.

"I copied it from Fluttershy. Applejack made one for her to help feed big animals. I thought it would be perfect for my BBBFF. It's modeled on a cow's teat," Twilight said, explaining the contraption.

It was perfect, like everything Shining's little sister made—in his own mind at least. Closing his eyes, a blush rose all the way to his ears as he suckled at the sweetened water. From experience, he knew how dangerous dehydration was for ponies, and could identify the slightest sting of salt in the water. He reflected on how good Twilight was at this.

"That first one was definitely a success. You noticed the self-lubricating throat? The undulations?" Twilight was ticking off features mentally, working through each item in her list only when Shining nodded. "That suit is configurable. I was thinking something more upright for the next test."

"Mmmff," Shining said, before he realized he needed to stop suckling to speak. Pulling back, he let the teat drop from his mouth. "D-Do you have something that will do the opposite?"

When Twilight Sparkle smiled, she brightened the day of everypony around her. When she smiled right now, to Shining Armor, he felt spirits lift in Canterlot. Radiance of the kind that beamed from Twilight was a rare thing.

"Yes," Twilight said.

Reaching out with her magic, Twilight didn't touch it to the plates that held to Shining's body, rather she adjusted the enchantments that could restraining him. "Hold right there."

The tremble of the equipment binding up again surprised Shining. He tried to walk, only for the suit to fight him. One step, then halfway through the next he found his leg getting harder and harder to life. He flexed all his muscles, straining again, and felt the outfit start to lock his movement. "Thank you, Twil—"

Shining's eyes widened as Twilight shoved the teat back into his mouth, and then a clang as it seemed to lock in place. He tried to push it out, but it was quickly apparent she'd used magnets to affix it to his snout. Smiling around the teat over his mouth, Shining Armor suckled a few times in contentment.

"This time I'll use something a little like the spell I'd put on you in the Crystal Empire. This, however, is a little more invasive. It needs to know everything about the nature of your impending orgasms. Please hold still." Twilight actually giggled at her own joke.

Unable to turn his head, Shining shuffled in place a little and felt the restraints grip tighter. As he was making a mental note to ensure to get the design for the suit to the Royal Guard, Shining felt something touch the end of his flagging penis.

A twitching, thin thing poked at his shaft, and Shining was wondering what it was about when it burrowed into him. Eyes shooting open, Shining felt Twilight feed the thing down his urethra, and felt it squirm and wriggle inside him.

Ignoring Shining's sounds, Twilight kept an eye on each of her teaser and Shining's horn. The former burrowed further into Shining's body, while the latter didn't so much as splash a hint of color.

Internal pressure built as Shining felt the thing inside him seem to split. Part of the tendril searching inside him found his bladder, while the other part found—well—something else. He was confused about both until the first stroke came.

A tremble passed through Shining Armor. His focus on tracking the things inside him was completely broken by the feel of the tendril in that unknown place moving. It didn't touch his aching shaft, it just—stimulated him.

"Your prostate is a dozen times more sensitive than any other part of your body, BBBFF. This toy is a long-term one. It will ensure you reach the edge of blinding pleasure, and it will keep you there. With the fluids, you could be stuck like this for days." The last word was whispered directly into Shining's ear. "When you are thirsty, suckle. This little creation will keep you from making a mess."

The stroking continued, and Shining's eyes quickly glazed over. He got three little bucks out before his body was restrained again, and then all he could do was stand there and let Twilight's toy molest the insides of his prostate.

It was every bit as sensitive as Twilight had explained. Shining made little whimpers as the tendril stimulated him in unbelievable ways. When the precipice drew near, he felt so close that he was sure the next twitch of the thing would push him over. But, as Shining got closer to the edge of his orgasm, the touches became fainter and fainter.

"Shiny?" Twilight said. She watched his ears twitch and turn toward her. "Are you there yet? Does it have you balanced?"

Shining Armor managed to nod his head once, then the suit restricted the movement any further. He trembled for a few moments, but the tickle of pleasure wasn't his release, just the device keeping him close to the edge.

Twilight watched as her brother twitched here or there, and watched as each movement was arrested by the suit before he could make it again. She listened to his moans and whines, and stroked her body. She contemplated pulling out the second suit and putting it on, though she didn't have anything to use on herself.

Suddenly caught in a sexually aroused, yet industrious state, Twilight tried to imagine all the devices she could use on herself. Magically programmed machines that would extract and wring every ounce of pleasure form her.

Time passed, and Twilight designed, tested, and discarded female toys in her head. Some she would build, but others were not meant to be. All the while, Twilight's eyes were glued on her brother. His own eyes were closed, and she could see them twitching from time to time. His mouth started moving, and she could see bubbles of air rise up through the tank that fed him.

When Twilight found the best candidate design, she imagined all the ways it could be used on a mare, though before she could get too far her own orgasm interrupted her. "Ohhhh!" She grit her teeth closed on the loud moan, then remembered the protection spell and opened her mouth.

Twilight's deep, extended moan of lust woke Shining from his daze of need. His shaft was impossibly hard and ready—he was sure that the slightest touch would give him the relief he needed, but there was nothing he could do now.

Then a strange, new sensation happened. The tendril that'd found his bladder did something, and the tight sensation of his moderately full bladder started to ease. The feeling of control that Twilight's devices had over his bodily functions was exquisite.

Listening to Twilight's masturbation—smelling her—Shining tried to imagine what she was thinking of. Was it him? Was it another stallion—maybe another mare? Shining suckled at the teat in his mouth, not even thinking about what the increased fluid intake would do.

Sliding back into that hovering dream, Shining wanted to scream, shout, yell, and beg, but ultimately what he wanted was to stay in this position forever. His mind revised forever to be "until Cadance is ready for him".

He didn't even realize he was still suckling the sugar-water until his bladder told him it was extra full. The tightness, the restriction of the tentacle inside him, made him ache for even that little release. Exerting what will Shining Armor still possessed, he managed to still his mouth from taking in more fluids, but that didn't save his poor bladder from growing further.

Just at the point where he thought he was going to burst, Shining felt the tendril begin to relieve him. The sensation of being drained was as perfect and refined as he could hope for. It wasn't a climax, but Shining took what he could get. Without a second thought—and knowing the tendril would do its work—Shining began to suckle again.

Watching the device under her brother's belly swell with his expulsion, then shrink back down as it disposed of it magically, Twilight let out a happy sigh and let herself get off on her brother's helplessness again. "Two hours this time, Shiny."

It might have been an hour, it might have been a year, Shining Armor didn't know. Suddenly, he needed to be out and free. He started by fighting the grip of the restraints, and they fought back. Struggling, whining, whimpering—none of it worked. Then he remembered what Twilight had told him centuries ago.

Focusing everything he could, Shining was about to launch his magic when his bladder began to empty again. The effort drained from him, and he floated for another eternity while his body's waste was evacuated. Then he pushed.

"Shining?" Twilight asked. She ignored her body and her needs, shoving to her hooves and walking over. Igniting her horn, Twilight undid the spell the suit held on her brother, and then caught him with her magic. "Shining, are you okay?"

The strong magnets holding the teat in his mouth were parted and it was pulled free. "N-N-Need break."

Twilight smiled. "Do you want to keep your friend inside, or do you want it out?"

"Out. Unless I can get off like this?"

"You can't. It's not just edging you with sensation. Hold still."

Holding Shining Armor in her magic, Twilight easily (for her, not so easily for most others) gripped the toy and deactivated it.

The feel of the tendrils withdrawing was better than pure sex. Shining moaned and made happy little sounds as each of the tendrils withdraw from his organs and were finally free. No longer tormented without relief, he managed to get his jello-like legs under him and stand.

"There you go. Do you—" Twilight didn't get any further. Shining raced to the door, raced out, and was gone. "… want me to remove the magic that was withholding your orgasm?" Twilight finished asking the empty room. "It will last—about five more minutes. Well, I guess you'll work that out on your own."

Shining heard nothing more from Twilight. He raced through the library for the one room he could have privacy from everypony—the lavatory. Securing the door behind him, Shining stood over the trough that was made for stallions' relief, and used what little magic he had with the suit on to masturbate.

It felt better than even the edging had. Shining Armor was in his own little part of paradise. Though the grip from his magic was weak, it was more than enough to bring him back to the edge of climax. Only, when he reached what should have been the moment of purest bliss, Shining Armor felt that same wall holding him back.

He didn't curse. Shining couldn't even get more than a strangled whimper out. He stroked his aching shaft with the lightest of touches, and lived on a knife-blade of exquisite release that seemed destined to be forever out of his reach.

Even freed, even outside the basement and without the thing inside him, Shining was still in his sister's grip. The realization made the moment worse, and while he could feel the arousal of his masturbation, it wasn't until the tiniest winks of magic deep in his body that he could climax.

Then that wink happened, and Shining Armor almost passed out in Twilight's bathroom. His balls had swollen, and now they jumped and bounced while he poured as much of his magic as he could into stroking his shaft.

Jet after jet of thick semen shot from Shining's shaft, painting the bottom of the trough and the back of his forelegs. Standing with his back arched, his body firm, and his cock rampant, Shining Armor made the biggest mess of his life, and he adored it.

His magic was weak, almost gone. Shining had put everything he had into stroking himself, and now the bondage suit was ensuring he paid the price for the excess. But Shining Armor didn't care. He was more alive and free than he'd ever been in his life.

Twilight waited, worried, for Shining to return. "Have I gone too far? I might have gone too far," she said to herself. "What if I went too far?" She'd gone from storm-in-a-teacup worried, to bits of frizzy mane sticking out at odd angles before she heard hoofsteps approaching.

The sound Twilight heard wasn't a weary pony dragging himself back, and they weren't sure and firm strikes of a stallion come to demand his freedom. Twilight almost stared in shock as her brother pranced into her basement. "Sh-Shiny?"

"Twily! That. Was. Amazing!" Rushing his little sister, Shining Armor scooped Twilight Sparkle up in a tight hug and squeezed. "How did you even come up with all this amazing stuff?" He quickly let go and posed in the magical bondage armor. "This? This is going to revolutionize the Royal Guard and the capture of dangerous creatures."

Relief mixed with the flush of pride for her creations, and both worked to pull Twilight out of her panic-spiral. She held up a hoof and booped Shining on the nose—while activating the restraints again.

"This has been so great, Twily, I—" Shining didn't realize the magic of the restraints had been activated until he tried to lift a leg to boop Twilight back. His hoof got almost level with his chest before the suit snapped it back down. His heart rate sped a little as he realized Twilight was gearing up for more.

"You've had a taste of denial, and being forced. But I wonder what you like more?" Twilight walked around her brother, examining him for any signs of harm from his treatment. Apart from needing a good bath, Shining Armor was still in top condition.

"Maybe I could try—?" Shining asked.

"The best way to test, I guess, is to put control in your hooves." Twilight spoke as if her brother hadn't said anything at all. She watched the expression in his eyes as he realized that. He was shocked and surprised, but he still didn't tell her to stop.

With her magic, Twilight floated out a rubberized stroker—a sheath to go around a stallion's member. "I came up with this spell as more of a general tool, but it will work perfectly here. All I need to do is add triggers for it, and provide an output.

"There is one trigger, BBBFF, your climax. The output is the bindings. But there is a timer."

Shining was getting hard just thinking of what Twilight had constructed this time. His mind spun with possibilities. He knew it was going to be amazing, whatever it was. So far as he was concerned, though Twilight had done things to him he'd never even considered before, all had been perfect.

The kiss of the rubber stroker on the tip of his flare made Shining tremble in the grip of the restraints. The soft rubber pushed down him, and with his recent drought of orgasms only barely sated Shining felt need swell within.

Working the stroker all the way down to Shining Amor's sheath, Twilight could see as the enchantment within it imbued her brother's penis with rigidity—he would not be losing his erection until it was removed.

Building up magic in her horn, Twilight Sparkle bound the spell to her brother's libido in just the right way to have his arousal be monitored, and then linked the output to his bondage. All she had to do after that was a little motion on his shaft, courtesy of the magic the suit leeched from Shining's horn.

"Try to use your magic, Shiny," Twilight Sparkle said.

Being a little recovered, Shining did just as instructed. When the toy started to move, Shining let out a happy groan. He rocked his body a few times, wonderfully aware of the bindings tightening with each movement he made.

"There. All you need is ten minutes without an orgasm and the bindings will loosen a bit, but a single climax locks it to full rigidity again. This,"—Twilight used her telekinetic field to give a more firm stroke of the animated toy—"follows your will, and can go slowly enough that you should be able to resist it, but a stray bit of magic and it will be fast enough that you can go as far as you want. It should take thirty minutes of no orgasming to free you completely."

Snorting out through his nose, Shining Armor traced the logic behind this one. He could just go thirty minutes and get free, particularly since he wasn't really worked up, but he wanted to see exactly what it was Twilight had wrought. Closing his eyes, he sent a little burst of magic through his horn. A deep, satisfied groan pulled from his throat.

Once he had the stroker in motion, it became so easy for Shining to feed it his magic. Little trickles meant slow, bigger bursts sped it up. Like his time masturbating, however, he could feel the strain the binding suit of metal put on his magic, but he wanted more.

A tremble of pleasure ran through Shining, and in one explosion of pleasure he climaxed. Power trembled through him as he was caught in a tight grip of physical release.

"And that reset the counter," Twilight said. "I'm not going to free you from this one, BBBFF. You'll have to get out on your own."

He'd had his fun. Shining smiled and relaxed his magic. Waiting, it was impossible to tell how much time had passed, but eventually he felt the tightness holding his head in place let go. Then a little thought crept into his head. Shining ruminated on how much effort Twilight had put into this one special day, and he thought it would be an absolute shame not to test her little spell.

With a devious grin, Shining let a tiny trickle of magic flow through his horn. A long, low groan filled the air as the stroker made deliberate and long motions. Shining's mental acuity turned to that of butter, but he held onto his new idea—only tiny bits of magic, and he wouldn't climax!

Having his cake and eating it too, Shining Armor strained in the grip of the binding equipment, struggled against the hold it had on him, while only letting the toy move super slow. The moment came when he felt it relax more, and he actually giggled in glee.

Moving was hard, but not impossible. The outfit fought against Shining's every movement, but it didn't snap back. Feeling proud of himself, Shining shuffled slowly toward the hose and teat where he could get a drink.

Twilight watched from the corner of her eye as Shining took each slow step. Her book on bondage for stallions was good, but she thought it leaned a little too far into using it as a step for sex. When Shining reached the teat hanging down, and latched onto it with his mouth, Twilight made note that the stroker sped up a little.

With the teat in his mouth, Shining could let his worries just roll away as he drank down the sweet water. He felt revitalized, bursting with new energy, he even risked letting just a little more magic leak from his horn.

Slowly stretching his limbs, Shining reached up one forehoof and touch the teat, only for the little clang of the magnets locking in place to startle him. Shining Armor barely even thought about it, he was thirsty after all. Suckling happily, he relaxed and let the stroker massage his length.

Eventually, he'd had enough to drink, and without thinking, Shining Armor reached out with his magic to pluck the teat free. His eyes widened as the stroker kicked into high gear. The feel of the self-lubricating toy gliding along the most sensitive part of his body was absolutely too much. With the teat locked in his mouth, Shining felt the electric trembling of an orgasm start.

The pressure was just too much for Shining, though he tried to deny his release. He clenched down for all he was worth, but the stroker was still working away at full speed. A tightness gripped his balls first, the electricity racing through him seeming to pour into the two orbs. Fire spread out from his scrotum in waves, and it consumed him completely.

Rolling his eyes back in his head, Shining Armor felt as his prostate took up the chant his balls had started, and together they plunged him into liquid bliss. Again and again, spraying ropes of seed down his shaft, Shining surrendered himself to the climax. It took from him, but gave back pure bliss.

Shining Armor arched his spine and pressed magic into his horn. He wanted more, he needed more, and there was just one way he would get it. More magic, more pleasure. Shining submitted himself to the desires of his body, even as the bondage equipment tightened its grip on him, and masturbated with the aid of Twilight's magic.

With her magic, Twilight lifted her quill and made note on a scroll. "That's your second."

Completely surrendered, Shining's ears didn't even twitch at the sound of Twilight's voice. He stared ahead and fed the stroker his magic, basking in the situation that had him lose so much control. There was no worry or fear of anything going wrong—he had the best sister in all Equestria looking out for him.

Feeding the magically-parasitic toy, Shining Armor drifted from one orgasm to the next. He drank when he felt he needed it, but otherwise just submitted to the ministrations of the situation. From one orgasm to the next, Shining pushed his magic out, but this time the stroker didn't respond.

Whining, he strained and struggled, but no magic made it through the tight grip of the restraints.

First Shining's head and neck was freed, then his legs were allowed strained movement, and all through those twenty-nine minutes, he ached for relief. Finally, the restraints released him, and Shining Armor folded into a pile on the floor.

"You got free!" Twilight knew the real reason her brother was free, it was part of the situation that she'd built that he'd hit this moment. With the simplest flare of her magic, Twilight first removed the stroker, then released the bindings from Shining.

This part was something Twilight Sparkle had been warned about. She had all the things she needed, however, and sent magic into her horn.

Shining Armor floated into the air. He panicked, thinking his sister had another game planned and he wasn't ready, but rather than ropes and bondage, he found himself wrapped in a warm blanket beside his sister, and the recipient of a hug.

A dam broke inside Shining. He leaned into Twilight and hugged her back. Sobbing, he held tight to Twilight as she told him how important and amazing he was. Then Twilight told him a name—Cadance.

Like a diver breaking the surface of a lake after a long time underwater, Shining Armor felt himself again. Relief and exultation wove through him. "Th-Thank you, Twily. Thank you so much!"

Twilight was still flabbergasted that she'd broken her brother in so much. He'd been completely gone and submissive, but now he was back. This new bond was tighter than before, they weren't just siblings anymore. "You're welcome, BBBFF."
