Chapter the First: Memories

"I can't believe you thought that looked good," Twilight Sparkle chuckled as she turned the page of the family album. She and Shining Armor were sitting on the couch in their parent's home. They were housesitting while their parents were away for the week.

"Look who's talking," smiled Shining Armor, nudging his sister's ribs. "That has to be the gaudiest Hearth's Warming sweater ever knitted. How in Equestria did you ever think that looked good?"

Twilight blushed. "Shut up. I was really into Daring Do at the time." She turned the page again. "And what's this you're wearing, brother dearest? Are those parachute pants? Why are you wearing gold nylon parachute pants?"

Shining Armor adopted a goofy grin as he puffed out his chin. "You're just jealous because I could pull that look off."

"Oh, really?" snarked Twilight. "Is that why your pop band hit the top of the charts? What was it's name again? Oh yeah. Ben, Ben, Ben, Francis and Francis."

Shining Armor let out a thunderous laugh. "I forgot all about that!"

Twilight chuckled. "So did I, until we started looking through this album. I thought you were really good."

"No one thought we were good, Twily. We never even finished a single song. I can't even remember why we used that name."

"I thought the name was cute. I thought you all looked really cute, too."

Shining Armor wrapped his hand around his sister's shoulder and pulled her into a hug as he turned the page. "Oh, look at this..."

"Oh, no," Twilight chuckled, putting her hands over her face. "What in Celestia's name prompted my to wear that ridiculous ensemble?"

"What?" chortled Shining Armor. "You don't think you look good in a pink leotard and tutu, with mom's fishnet stockings on your arms?"

"No," grumbled Twilight, trying to hide her shame. "Turn the page."

The next page was more wholesome. Twilight was riding atop her brother's shoulders as they went door to door selling jerky at a hefty markup. They were raising funds for one of Shining Armor's friends, who had been injured in a game of sportball.

"We used to hang out all the time," smiled Twilight. "Those were the good old days."

"Good old days?" chuffed Shining Armor. "You're making me feel old."

Their attention was simultaneously drawn to a loud knock at the front door. Twilight stood up. "Then rest your weary bones here on the couch, you old fart, while I get the door."

Twilight opened the door to find a young mare outside the door. "Miss Twilight Sparkle or Mister Shining Armor?"

"I'm Twilight Sparkle, yes."

"I have your order ready." The mare held up a cardboard box, with a few smaller plastic containers in it.

"Oh, yes, thank you," chuckled Twilight, taking the box. "We weren't expecting you for another fifteen minutes, at least." She placed the box on a table just inside the door and brought out her wallet. "Twenty-four bits total, right?"

"Yes ma'am," smiled the mare, accepting the payment. "Thank you for ordering from Golden Fireball."

The door closed, and Twilight carried the food into the dining area. She separated everything to be split perfectly down the middle, having a small panic attack when she found an extra spring roll. After solving the situation by cutting it in half, she poked her head back into the living room. "Hey! If your old bones can handle the trip to the table, dinner's here."

Before he came to the table, Shining Armor disappeared into the kitchen and pulled from the freezer a bottle of wine he had brought with him and two glasses. After receiving a questioning look from his sister, he explained himself. "This is Cadance's favourite wine. Since we don't see each other as often as we like anymore, I brought us a few bottles to make it a special occasion."

"You always were a hopeless romantic," Twilight sighed, taking her seat as her brother poured a glass for her. The label said it was a honey wine. Twilight wasn't well versed on the subject of alcoholic beverages, but she knew that honey wine was also known by a more common name: Mead. She also knew that it was usually yellow or orange. This one was bright red, almost pink.

They enjoyed their meal, and returned to the couch with the rest of their wine. They were already fairly tipsy, though not quite to the point where they would stumble yet. Being done with their foray into the photo album, they curled up with their books. Shining Armor had a historical fiction novel depicting numerous soldiers at war, where the first half of the book took place over several months and the latter half was all in one afternoon. Twilight had an encyclopedia detailing the machinations of ancient castles that were made without the use of magic. They did not stop drinking until the words began to blur on their pages.

"I can see why Cadance likes this stuff," giggled Twilight, pouring herself a fresh glass. "She drink this stuff all the time?"

"All the time," snickered Shining Armor. "She has a standing order with the local brewmaster. Five gallons every month. With variations, of course. This was a bigger bottle than she uses, though. I thought it best, considering we have twice as many livers."

Twilight's laugh was louder than she intended it to be, a common end result of too much wine. She didn't seem to notice, though, and her brother didn't seem to care. "I really missed doing stuff with you, Shiny," she said, resting her head on his shoulder.

"Yeah," he responded, aerating his drink. "We don't often have the chance to be intimately aware of each others lives." He wrapped his hand around her shoulder again, lightly squeezing her into a soft hug. "It's a real shame we can't do stuff with each other more often."

"If I had my way, we'd be together every night," said Twilight, wrapping a blanket around them. In order for the blanket to fit them better, Shining Armor dropped his hand from her shoulder to her waist. "Wouldn't that be lovely, Shiny?"

"It certainly would be," replied Shining Armor, pouring himself another glass of wine. "Hanging out with my cute sister all the time? Name one stallion who wouldn't want that." They shared a chuckle and snuggled up under the blanket.

Chapter the Second: Awakening

As the sun crept higher into the sky, a beam shone down on Night Light and Twilight Velvet's abode. It was a small beam, thin enough to penetrate a tiny gap in the curtains, but large enough to cover an eyeball. With all the might of the sun itself, the beam of light reeled back and punched Twilight in the face hard enough to wake her from her slumber.

She rolled out of bed and rubbed her face. It dawned on her that she'd had too much to drink last night, as evidenced by the rooms spinning visuals and the cacophonous screaming of the bedsprings. She wiped her eyes and stood up, stumbling into the nearby bathroom. With a few splashes of cold water, she looked up into the mirror to see the dripping face looking back at her.

"You need moderation," she chuckled, immediately regretting the statement as it echoed in her ears. "Moderation and coffee." She took a closer look, and found a small, nondescript white glob on her cheek. "And a shower." She stripped off her clothes and stepped into the shower, still half asleep. When she finished washing up, she felt much better. As she wrapped the towel around herself, she looked down at the apparel she had taken off. These weren't her clothes. They were much too large. She picked up the shirt, and recognized it as one of her brother's. Perhaps she had become sick last night and he had offered it to her so she could go to bed with clean clothes? How thoughtful of him.

With another look around, she found that she wasn't just in any bathroom. This was their parents' bathroom. It was only accessible through the master bedroom, meaning that was the bed she had been sleeping in. She hadn't been here in some time. Perhaps her bed had been used as temporary storage, and she couldn't sleep in her own bed because there wasn't enough space? Shining Armor really did think of everything, didn't he? In fact, she wouldn't be remotely surprised if he was already up, and had a fresh pot of coffee ready for her. She picked up the clothes he had lent her and tucked them under her arm. She would wash them for him, along with the sheets for their parent's bed.

She stepped out of the bathroom and into her parent's bedroom. Her eyes went wide. Not because her own clothes were scattered all over the floor. Not because her panties were dangling from the ceiling fan. Not because of the almost empty bottle of wine still dripping on the carpet. The shock she felt was from seeing the stallion that was still sleeping in the bed she had woken up in. He lay on his back, and had all of his limbs splayed open with the exception of his left hand, which was rubbing his chest. He was softly snoring, as far as Twilight could tell. The worst part of it was, he wasn't covered at all. Twilight Sparkle gazed down at the stallion she had slept with, her eyes transfixed on his massive erection.

Suddenly, it twitched, and a small dribble popped out of the tip, running down the shaft and dripping into a small puddle beneath his balls, which were looking a bit shriveled by now. Only after seeing his pre drip onto the mattress did Twilight realize that the stallion wasn't snoring. The gentle intermittent hum she was hearing wasn't coming from his mouth, but rather, his arse. Shoved between his cheeks was a small plastic case with a silicon tube on the back. A wire ran from the case to a small remote strapped to his thigh, and the remote was set to the "Slow Pulse" setting. Every few seconds, the rubbery mass would vibrate momentarily.

With a gentle touch, she slowly removed the dildo from the stallion's arsehole. Every so often, he would let out adorable moans and whimpers. Feeling particularly mischievous, she stopped when she reached the medial ridge and started pushing back in. The stallion seemed to like it, his legs spreading to allow it further into his rectal cavity. Twilight chuckled, then returned to her original task of pulling it out. With an audible pop, the head slipped out of the now gaping hole it had been in. She turned it off and tossed it under the bed, resolving to clean it later, before finding out where it was supposed to go.

Twilight's mind was filled with dark questions. She was starting to remember bits and pieces of the night prior, though not the whole thing. She knew she had ridden his face, but did not recall whether or not they had sex. She now knew what the white glob on her cheek had been, so she assumed she had returned the favour, but she had no recollection of what he tasted like. A voice in her mind asked her what the harm was with another lick, and her curiosity took hold of her. She stuck out her tongue and gave his tip a taste before he could become completely flaccid. The flavour was salty and savory, as was the scent. It wasn't awful, and he was pretty big. Perhaps they'd do this again, but before that happened, Twilight vowed to pick up a notebook. This time, she would record her findings.

She covered him with a sheet and left the room, taking her clothes with her. Her first task was to dress herself in her own clothing, which she would find in her own dresser, in her own room. Once that was done, she went to Shining Armor's room, finding a suitable outfit, and leaving it outside her parent's room, where the stallion would find it with ease once he awoke. Finally, she had to prepare breakfast: Eggs over easy, pancakes, a grapefruit, and a piping hot cup of coffee for everyone involved. She had only just finished putting it all together when she heard her parent's bedroom door close for the second time since her trip to the kitchen. Into the dining room walked the stallion she had slept with and presumably sucked off. The one she would be doing the same with tonight, if she set up similar parameters. He came into view rubbing his eyes.

"Morning, Twilight," he yawned.

"Good morning to you, too, Shining Armor."

Chapter the Third: Research

Once again, it was time for dinner. This time, they were having pizza. After Twilight set the table, Shining Armor came in and sat down. No alcohol did he bring with him, a fact that did not slip by Twilight. "Did we run out of wine?"

"No," said Shining Armor. "There are still a few bottles left, I just... Did anything weird happen last night?"

Twilight looked away. "Not really. My memory of last night is a little fuzzy."

"Mine too. And when I I woke up this morning, I was in a bit of an awkward situation."

"What kind of situation?"

Shining Armor blushed and looked away. "Just... An awkward one. It's embarrassing."

"Well, like you said yesterday, this is a special occasion for us. I want to enjoy it."

"I mean, it was nice, but I don't want a repeat of last night."

"Why?" asked Twilight. "What happened last night?"

"I don't know."

"So what's the problem?"

Shining Armor sighed. "Okay, Twily. I'll bring out the wine." He stood up and left the room, coming back with a bottle of wine in his hands. After uncorking it, he poured a glass for his sister and himself.

Twilight would have to be careful. She wanted to take notes on how they progressed, and she couldn't do that if she was too innebriated to write. She would have to match his expectation for now, but once his attention was weakened, she would be watering hers down so as to stay in control.

Their routine from the previous night was similar to tonight. However, Twilight had a small memo pad inside her book, which she would regularly record her findings in. Not that there were very many findings thus far; She was mostly recording how many glasses he'd had versus how many she'd had, accounting for the water she'd diluted it with. She was beginning to think that perhaps it wasn't going to happen tonight when Shiny suddenly closed his book.

"Twily," he slurred, "I feel awful."

"I'll fetch a bucket."

"No, that's not it." Shining Armor placed his cheek on Twilight's shoulder. "I lied to you, Twily. I remember everything from last night."

"You know what would help make you feel better?" asked Twilight, sliding her book aside and focusing on her notes. "Coming clean and clearing your conscience. Tell me what we did."

"I think the wine contained aphrodisiacs," he said, placing a hand on her abdomen. "Cadance said she'd put together a new mixture with aphrodisiacs mixed in, and I think I grabbed the wrong bottles by mistake. That's why, when you wanted to cuddle, I grabbed your arse. That's why we kissed."

"Why didn't you tell me that at dinner tonight?"

"Because part of me thought it was hot. Part of me think's you're hot." He slipped his hand under her shirt and slid up past her bra, cupping her breast in his hand. Just as Twilight was about to push him back out, he started playing with her nipple. Expertly so, too. He seemed to know exactly how she liked it. She could feel her loins starting to churn as the drugs took hold of her. She squeezed her eyes shut and let out a small moan. He silenced her by shoving his tongue into her mouth.

They stayed like this for a few minutes, until Shining Armor's other hand slipped into Twilight's panties. This time, she had the discipline to grab his wrist. "Shiny, no," she said, looking sternly at him. His eyes went wide as he laid his chin on her chest. She could never resist those begging eyes. Even if she could, it was her fault he was in this state. "Not here, at any rate. Come on."

She pulled him off the couch and back to their parent's room. She could see the massive bulge he was already sporting tightening his pants as she pushed him onto the bed. "Strip down, Shiny. Momma wants to see what daddy's packing." Even as the words left her mouth, Twilight couldn't believe what she was saying. Was that the wine talking?

Shining Armor tossed his clothes aside as if they were venomous snakes. He lay there on the bed, his erection pointing straight up like the mast of a ship. The air around it was soon filled with his musk, and Twilight found herself unable to resist the intoxicating stench. She had to have it inside of her. She was able to exercise a small amount of restraint, however. If it was going to go between her cheeks or slip inside her moist lips, they would be those of her face.

He tasted better now than he had this morning. Whether it was the drugs making that happen or just because it was fresh, she couldn't tell. She just knew that the taste was driving her wild. It was all she could do to keep writing her notes. She had no idea what she was writing, she would have to find out later, but if it came to mind at this point, she would write it down.

She soon tasted his ejaculate. He hadn't lasted very long at all. Despite that, he wasn't softening, even slightly. Most stallions would enter a refractory period at this point, but Shining Armor was as hard as when they'd begun. She contemplated going down on him again, but he grabbed her by the elbows and pulled her up onto the bed, then slipped his hands down to her hips, sliding them forward until she was sitting on his face. Shifting her panties aside, he dug his tongue up into her delicate folds, tasting the wetness that had accumulated there.

Twilight bit her lip. This part, she had remembered, if only slightly. She knew they had done this, but she couldn't remember how amazing it had felt. She pulled her shirt off, as well as her bra. Her skirt and panties had to stay on while their bodies were intertwined, but she made a note to remove them the first chance she had.

It turns out Shining Armor hadn't lasted very long because of the aphrodisiac they had ingested. This was proven when Twilight clamped down on her brother's tongue, coating his face in her vaginal discharge. As he licked it off of her slit, she knew that tonight would be a very long night indeed.

Chapter the Fourth: Development

The siblings showed no sign of slowing down. Before Shining Armor could wipe his face, Twilight had already aligned the tip of his cock with her vaginal entrance. In the next moment, he was inside of her, being milked by her spasming musculature.

Twilight was in absolute ecstacy, the feeling of fullness compelling her to lose herself to him. Despite that, she still held on to what little shred of self control remained, as that was the part controlling her pen. She would need those notes to recreate this experience. While part of her questioned whether or not it was wise to recreate it, the pleasure she was feeling at this moment demanded that she at least try.

Twilight grabbed Shining Armor's wrists and pulled his hands up to her breasts. Once his thumbs found her nipples, he began rubbing and massaging the soft mammaries. Her hands relocated to his chest, gripping his pecs as her hips started to piston slowly.

After several minutes, Shining Armor's hands shifted to his sister's hips and he sped up. For the first time that night, Twilight's mind was so occupied by the pleasure that she dropped her notes. Presently, he pumped a load into her awaiting womb. Had she been able to think clearly, she would have been horrified by the fact that she was not taking any form of birth control, and she may very well be carrying an incestuous baby inside of her for the next nine months. However, as her mind was fully enveloped in endless pleasure, she didn't really care right now.

As she rolled off of him to catch her breath, her foot fell off the bed and brushed against the dildo. She reached down and picked it up, waving it in her brother's face. "Tell me, Shiny. Where did you find this thing?"

"It was in that box," Shining Armor said, pointing to the foot of the bed. "The one you found yesterday."

Twilight climbed off of the bed and pulled out a large wooden box from the foot of the bed. "This one?" Shining Armor nodded. Opening the box, Twilight was met with a wide assortment of sex toys. From vibrators to butt plugs, from strap-ons to ball gags, this trunk had a vast arsenal. There was even a gallon jug of lubricant, which was almost half empty. What kind of crazy sex did their parents have?

There were sanitary wipes, so she cleaned the dildo and placed it back in the box. She would have no idea how to explain why the batteries were drained, but she hoped the question would not come up in conversation. As she was securing the toy in its slot, she found herself staring at another, and she felt compelled to try it out. Casting her panties aside, she put her feet through the leg holes in the strap-on and slid it up to her waist. It had a horn insert inside the front, and a butt plug secured to the back. With Shining Armor's seminal fluid leaking out of her, it was very easy to slide these into her holes and secure them in place.

With the straps tightened down to keep the belt from moving around, Twilight lubricated the shaft and returned to her brother, who had lifted his legs in preparation for what she was planning. His cheeks flushed red as she placed the tip against his pucker, and he let out a loud moan as she pushed into him. This dildo was smaller than the one they had played with last night, but certainly more involved.

"Yes, daddy!" shouted Shining Armor. "Fuck my tight boy pussy!" Twilight, while not Shiny's father, was more than happy to oblige, as every thrust was met with an adorable moan from her brother. She gripped his thighs for better leverage as she slammed into him repeatedly. Every thrust pushed back against the strap-on as well, pushing the horn back and forth inside her vagina.

Soon, his moans became too much for her to handle, and she had to find a way to shut him up. She leaned forward and shoved her tongue into his mouth, dripping the massive collection of drool she had accumulated onto his neck and chin. This worked for a few seconds, but their bodies were moving too violently to keep their teeth open, and they kept accidentally biting each other's tongues. Then she remembered the gags that had been in the box. She reached in and pulled out the first one.

Most kinky ponies would have access to a ball gag. It was an effective method of silencing one's partner. Others would step up from that, using a bit or bar gag, to press the tongue down. The benefit gained by this is that you can drain fluids into your partner's mouth, which you can't do with a ball gag. The next step from there were ring and spider gags, which held the mouth open enough that you could insert solid objects. If the ring was wide enough, you could even shove your entire cock in without fear of the receiver biting down. While all of these were in the box, none of them were what Twilight grabbed.

Were it not for the fact that it was in the gag section of the box, Twilight might have mistaken this for another strap-on. It was a rubber dildo that had a firm tube running its entire length. The purpose of this one was to make your partner feel like they had a cock firmly embedded in their mouth at all times, while still being able to breathe. Shining Armor took the whole thing in one go, making Twilight wonder how many stallions he had been with in the past. Still, he was quiet now, and that let her focus on her thrusts.

Neither of them lasted much longer, with Shiny being the first to blow. In a flash of white, both of their faces were covered in spunk, along with the bedspread, the carpet, and part of the wall. Twilight followed soon after, though hers was mostly contained by the belt she wore. It leaked out, certainly, but it didn't squirt everywhere as it had the last time. She collapsed next to her brother, both of them gasping for breath and covered in each other's sweat. That's how they fell asleep that night.

Chapter the Fifth: Home

The following morning, Shining Armor was the first to wake. His back was very sore, as was his jaw. He reached up and undid the gag, letting the dildo slip from his mouth, flexing his jaw a few times to relieve the stiffness. The room was even more wobbly than it had been yesterday. As he sat up, he realized that he was completely nude again. Memories of last night came flooding back, and as he combed through them, he saw something he had glanced over last night. Twilight's mead had been a different colour than his own. Less opaque, as if she had been watering it down. He turned to look at his sister, who was still sleeping next to him, her breasts rising and falling with her every breath. "Clever girl."

Placing his hand on one of her boobs, he gently moved it around, being careful not to wake her. She was smaller than Cadance was, but that was okay. Twilight's breasts were easier to manage. When Cadance became too excited, a stray breast smacking you in the face could spell a poor night.

Despite his best effort to be gentle, Twilight awoke moments after he began. "And a good morning to you, too Shiny."

Shining Armor pulled back his hand. "Sorry, I was just--"

"I didn't tell you to stop, doofus." She grabbed her brother by the wrist and returned his hand to her breast. "Keep going, it felt nice."

Shiny smiled and continued fondling his sister. "So we're just okay with this, then?"

"I think so," said Twilight. "I mean, I don't want to proclaim it to the world, or anything, but fooling around with you was really nice, Shiny. You knew me so well, it was scary."

Shining Armor chuckled. "Lucky guesses, all of them."

"Speaking of guesses, I'd have never guessed that you'd enjoy being filled from both ends. Where did that come from?"

"Sometimes, Cadance calls a few guards to join us in the bed. I think she likes me being her little bitch boy."

Twilight smirked. "I think she sees how much you enjoy being her little bitch boy." The two shared a laugh. Twilight sat up, pushing her brother back down onto the bed. "I'd also never have guessed how much I like being your dominatrix."

Shining Armor grabbed his sister by the shoulders. "Twilight, We only have a few hours before Mom and Dad come home. As much as I'd love to feel you railing my arse, we don't really have the time."

Twilight looked over at the clock. Her brother was right. They had to clean up, or their parents would find out what they'd done in their bed. That would be very bad. "Okay. You pick up the toys and put the box back, I'll go do the laundry and make coffee."

The two set about their respective jobs, making sure that there wasn't any mess left for their parents to discover. There was a problem on Shining Armor's end, though, as Twilight was still wearing the strap-on she had taken out. There were other things he had to consider, however, as the carpet had stains from his semen, as well as from the mead they'd spilled on the first night, both of which had dried. He resolved to ask Twilight for the belt later, as the carpet needed his immediate attention. He only just managed to have the stains extracted by the time Twilight came back with the sheets. "Twilight, the strap-on."

"We don't have time for that, Shiny," said Twilight, misinterpreting his meaning. "We still have to shower. Which reminds me, I brought your clothes."

"No, Twily, I meant--"

"Unless you want to shower together? We can save some time, and we won't be fighting each other for water pressure. Actually..."

"Twilight, I need you to--"

"Say no more, Shiny." She grabbed him by the elbow, pulling him into the bathroom, tossing him into the shower, and drowning out his protests with the spray of hot water. As she pushed the dildo into his exposed arsehole, she finally realized what he was trying to say, but wasn't about to stop. He was letting out the most adorable moans she'd ever heard. He really did enjoy being her little bitch boy. She could tell by the way he was furiously masturbating.

Luckily for them, the shower cleaned up easily, as did the strap-on, once Twilight finally took it off. As they stepped out of the shower and dried off, they decided that, since they were parting soon, they should bless each other with a token with which to remember their weekend. Twilight accepted Shining Armor's boxer shorts, and Shining Armor wore Twilight's panties and bra. They wore their regular clothes over the top of them, so as not to arouse suspicion.

With everything cleaned up and a hefty spraying of air freshener to cover the smell, they agreed that the house was spotless, and adjourned to the kitchen for lunch. Only ten minutes or so after sitting down to eat, they heard the front door open, and went to greet their parents.

"How'd you kids do all weekend?" asked Night Light, wrapping his arms around his daughter.

"Dad, please," responded Twilight. "You know Shiny and I. We're thick as thieves, as they say."

"So what did you do all weekend?" asked Velvet.

"Aw, Mom, don't make us go into all the details," chuckled Shining Armor. He was panicking inside, but he had an amazing poker face. "We just spent a lot of time together. We talked about books, looked at old pictures... You know, fun stuff."

"Well, if you're free in two weeks, we need to go to Trottingham. If you wouldn't mind helping out again, we'd like for you to housesit for us then."

Twilight smiled. "Why, of course we will. We'd be more than happy to. Just let us know the days and we'll be here."

"Yeah," agreed Shiny. "We're already looking forward to it."

"Well, that settles it," smiled Night Light. "We'll see you then."

On their way to the train station, Twilight pulled her brother aside into a small alleyway where they wouldn't be seen. "When we come back for that, we need to bring our own toys."

"Agreed. We'll also need lubrication."

"And most importantly," added Twilight, pressing her brother against the wall. "Bring the correct mead, okay?"

Chapter the Sixth: Preparation

When Twilight returned to Ponyville, she didn't go straight home. No, that would have to wait. She had assigned herself an errand that had to be done right away. Strap-on dildos don't buy themselves, after all. Even if they did, she would need to pick it out. It would just be easier if she were to purchase it herself.

Ponyville only had one store that sold adult toys. It was owned and operated by an older mare who personally guaranteed that all products were properly designed for the user's pleasure, and safe to use. Many of her customers were not made aware of this fact, for fear of driving them off. Those that did know about her private product tests were also informed of exactly how dedicated to the craft she was. There was a backroom to this store, with a workshop where you could have a custom dildo made. If you wanted an exact replica of your own cock to find out what your partner was experiencing, this was the place to go.

Twilight entered the building. It was unassuming on the outside, but on the inside, she was met with a rainbow wall of dildos of all different shapes and sizes. It dawned on her that this task may be more daunting than she had initially thought. This would have been much easier if she'd had Shining Armor pick out the right one for himself.

"Can I help you, sweetie?"

Twilight jumped in the air and turned around. She had been startled by the proprietor. "N-no, I'm just... Looking around."

"Looking for anything in particular? If so, I can help you find it."

"No, no, I'll just look around for a bit." Twilight blushed and backed away, tripping over a small stack of shopping baskets.

"Are you alright?" The mare came over and offered her hand to help Twilight up, but Twilight refused it, picking herself up.

"I'm fine, just a little nervous, is all."

"Okay. Well, in that case, I'll let you look around for a bit. If you can't find what you want, let me know, and I'll do what I can."

Twilight nodded and disappeared behind a shelving unit. She had been embarrassed enough today, she wasn't interested in telling this stranger her sexual preferences. She looked around until she found the section with the strap-ons. It took up perhaps half of an aisle. However, even the kinkiest of these didn't come with a butt plug. Most of them didn't even come with a vaginal insert, and none of them were the same size as the one she'd found in her parent's box. She let out an exasperated sigh.

"Having some trouble?"

"It's fine, I just have to pick one and hope for the best."

"If you tell me what you're looking for, I might be able to find it in storage."

"I don't even know if you'd have it."

"Neither do I, until you tell me what it is you want."

Twilight sighed. The mare had a decent point. She exited the aisle and approached the front desk. "I'm looking for a strap-on dildo that has inserts for both the front and back. Do you have anything like that?"

The mare shook her head. "No, but I can have one made by the end of the day, if all goes well. If you like, I can even fit it to your exact shape. Unless, perhaps, you wanted this for a friend to wear?"

Twilight shook her head. "No, no, this is for me."

The owner smiled. "Great. The first thing we need to do is select your inserts. Do you know your size?"

"Size? Aren't they all about the same?"

The mare chuckled. "No, sweetie, they're not." She reached under the desk, pulling out two dildos. they were exactly the same model, but very clearly different sizes. "This one is a size small, it's most often used by stallions who want to start practicing at the easiest level before trying for something bigger. The other is an extra extra large, and is reserved for only the most advanced users. You'd be surprised how much difference an inch makes."

Twilight stared at the difference between them. The small one would be easily concealed in a pocket, if she needed, but the extra extra large had a greater diameter than her forearm, and about the same length. "What does the medium look like?"

The mare fished around under her desk and came up with a medium. "I'd recommend this size to you, I think. I would guess you have experience, based on what you're asking for, but you're also a bit petite. If you'd like to try out the fit, there's a back room." She pointed to a curtain at the back of the room.

"Thanks," smiled Twilight meekly, taking the dildo to the back room. To her surprise, the mare followed her back. "Do you always watch these fittings?"

"I'll also be needing your measurements. If the inserts don't line up properly, it could cause severe discomfort. I'm also the only one with the key to the first aid cabinet, so there's that."

The back room had a chair with stirrups, allowing full access to whoever was sitting on the adjacent stool. As per the mare's instruction, Twilight stripped her boxers off and placed her feet in the stirrups. The mare had washed her hands and put on gloves, goggles, and a mask before sitting down.

"Why all the getup?" asked Twilight, more out of curiosity than offense.

"In case you squirt, I don't want it going in my eye. As for the gloves, I don't want to risk you ending up with a UTI because of me. Rest assured, everything that goes inside of you is sterile and safe. Now, you wanted double inserts?"

Twilight nodded. "Can we try medium for the back and large for the front?"

"Of course." The mare inserted a large, nondescript dildo into Twilight's vagina and a medium into her arse. Both were attached to a handle and lightly jostled to simulate how they would shift while thrusting. "How's that feel?"

Twilight was panting with her tongue out. It felt wonderful. "I'll take it."

"Good," smiled the proprietor. "I'm glad I could help you find what you were looking for. Now, if you'd go pick out the dildos you want, I'll be waiting right here."

Chapter the Seventh: Initialization

Shining Armor had help with his purchases. It turns out Cadance was really into the idea of her husband in panties. She took him to the local clothier to find him some lingerie.

"So, the first thing you'll need is a cotton set. You're going to need that to sleep in. The lacy set is only for special occasions. Oh, and a nice, feathery nightie made from a smooth mesh, so we can see right through it."

"I'm glad you're so excited, Cadance, but you should calm down a bit," said Shining Armor, shushing her with his hands. "We don't want the whole empire hearing about this."

"Oh, they won't mind, Shiny," reassured Cadance. "More than half the guards know how you like to be bedded, and it's only encouraged them to do better to gain your favour."

"Well, yeah, but..."

"Besides, it says nothing about your ability to govern them. You've been doing good so far, right?" Shining Armor nodded. "Then there should be no problem, should there?"

"I guess not." The carriage pulled up to the shop and the two stepped out onto the street. As Shining Armor looked up at the sign, he was very confused. "This isn't a clothing store."

The store they entered was not a clothing store, though it did sell clothing. It was an adult toy shop, and one of their best selling items was a pair of vibrating panties. While Cadance was certainly planning to purchase a set for her husband, she had other things she would have to buy first.

"How may I assist-- Princess Cadance!" The clerk leaped from behind the desk and ran up to one of his most frequent customers. "Wonderful to see you again. How did you enjoy your werewolf friend?"

"Werewolf?" asked Shining Armor, thoroughly lost. "What werewolf?"

"I'll show you when we return to the palace, dearest," chuckled Cadance. "I enjoyed it quite a bit. That knot was a bit of a struggle, but I managed eventually."

"Glad to hear it," smiled the clerk. "What are you looking for today?"

"Well, as you can see, I've brought my husband along."

"You're a lucky stallion, sir," chuckled the clerk, vigorously shaking Shining's hand.

Cadance's face twisted into a slightly sinister smirk. "We'd like to have him outfitted with a few basic pieces of gear. I was thinking we start off with a vibrating plug and a cage."

"Cage?"

The clerk smiled. "He's finally accepted it, huh?"

"Accepted what?"

"A nice, wide ring gag, too," added Cadance. "I want him to still be able to take one of the guards from the front end while keeping silent."

"Don't I have a say in this?"

"Of course, Princess," replied the clerk, grabbing Shining Armor by the wrist. "I'll have him fitted right away. You can even walk him out of here wearing his new equipment. Would you like a collar and leash, too?"

"I very much would, thank you." She waved to her husband as he was being escorted away by the clerk. "Bye, Shiny. I'll see you in half an hour."

The clerk escorted Shining Armor to a small room in the back and sat him down on a bench. "Alright, take off your pants and let's see what size you are."

Shining Armor was quite confused by the whirlwind he had just been through. Not knowing exactly how he had made it this far in, he had no idea how he would make it out. He reasoned that the best solution would be to just accept what was going to happen to him. Clearly, Cadance trusted this clerk, so he must know what he was doing.

With Shiny's pants sitting on the floor, the clerk frowned and shook his head. "I know those are cute panties, but they're too small for you. You'd look much better with something in your size, and it would be much more comfortable. Take them off, too."

Shiny did as he was told. "Even if they're the wrong size, I want to keep them. They're special to me."

"I completely understand, sir, but look at those marks on your hips. Those come from wearing clothing that's too small. Think for a second about how your boyfriend would feel. You take him to your bed, he removes your skirt, takes off your panties, and is met with those marks. It's a pair of phantom panties that he can't take off to admire your magnificent buttocks."

Shining blushed. Thinking about being fucked by a stallion had given him the beginnings of an erection.

"We'll have to take care of that, too," smiled the clerk. "You're to be fitted with a cage, and I think I have just the right one." He moved to the back of the room and shifted several boxes aside before pulling out a wireframe chastity cage complete with lock. "You're a big boy. And big boys need big cages."

After thoroughly washing his hands and putting on a pair of gloves, the clerk grabbed Shining Armor's semi-firm cock in one hand and a small ice pack in the other, rubbing them together. "We need the swelling to go down as much as possible," explained the clerk. "Otherwise, you won't fit in the cage."

"What's the point of the cage again?" asked Shining Armor, shifting uncomfortably as his dick was being frozen.

With it now being small enough to fit, the clerk slid the cage up Shining Armor's shaft, locking it tightly around his testicles so that it couldn't be removed without the key. "It stops you from having an erection," replied the clerk. "Eventually, when the keyholder decides to let you go, that first load will be a huge relief. Trust me, it'll be like nothing you've ever felt before."

With the cage now in place, Shining Armor looked down at his cock. A vision of Twilight riding it flashed through his mind, prompting another erection, but all he managed was to tighten the cage uncomfortably around him. "So, how long do I have to wear this cage?"

"Until Cadance releases you, of course. She'll be walking out of here with the key, so if you want it off, you'll have to discuss it with her."

Shining looked down at Twilight's panties on the floor. In two weeks, he would be with his sister again. Would Cadance then allow him to take the cage off?

Chapter the Eighth: Reunion

The next two weeks took ages to pass. Which is to say, they passed by at normal speed, but Twilight and Shining were so excited that the time seemed to pass ridiculously slowly. The day they received the notes from their parents, they were so giddy that they jumped for joy, quite literally.

Twilight arrived first, carrying a duffel bag. "So, weekend trip to Trottingham, huh?"

"Yeah, just a light business trip," chuckled Night Light, giving his house key to his daughter. "We need to make sure that what we set up on our last trip is working properly. If all goes as planned, this should be our last trip for awhile."

"A real shame," groaned Twilight. "I was looking forward to more time with Shiny."

"You can still visit him in the Crystal Palace, can't you?"

"I suppose, but then all of the crystal ponies will feel free to interrupt. The only quality time we can have is when neither of us is able to be reached by our responsibilities."

Just then, there was a knock at the door. Twilight Velvet answered. "There's my big, strong boy. How are you, Shiny?"

"I'm very well, thank you for asking," responded Shining Armor. "Is my little Twily here yet?"

"Over here," waved Twilight. Seeing his little sister caused Shining Armor's heart to soar. Seeing the duffel bag at her feet, however, made him very nervous. He had no idea what kind of toys she'd brought.

"Well, I suppose that's our cue to leave," chuckled Night Light. "You two have fun this weekend. We'll be back on Monday, around noon."

As their parents walked out the door, the siblings' anticipation grew. They knew they'd have to wait an hour before starting to give their parents a chance to catch their train, but the waiting was just terrible. As soon as the door was closed, Shining Armor grabbed Twilight by the wrist, pulling her up off of the couch and wrapping his arms around her. She responded by wrapping her lips around his tongue.

"I missed you so much, Shiny," Twilight moaned as she grabbed her brother's butt. She could feel the panties he was wearing through his pants.

"I missed you too, Twily," responded Shining Armor, slipping a hand up her shirt and rubbing her breast. "I have so much I want to tell you about."

"How about you show me, stud?"

Shining Armor chuckled. "Not yet, Twily. First thing's first, I brought the right mead this time." He reached into his bag, pulling out several bottles of mead. These looked exactly the same as the old bottles, save for a small x at the bottom of the label. With the wine in the freezer, the two sat down on the couch and began discussing their exploits for the past two weeks.

"So that's how I ended up with my own custom strap-on," concluded Twilight. "What about you, Shiny?"

"Cadance hasn't let me cum since I went back. She had me fitted for a chastity cage and hasn't let me take it off."

"You have a chastity cage?" asked Twilight excitedly. Her hand flew to her brother's crotch. She could feel something hard between his legs, but it certainly wasn't swollen. "You really are her little bitch boy."

"Twily, ple--"

"Shush, little bitch boy. From now on, when we're alone, I want you to refer to me as Mistress."

"But that's what I call Cadance..."

Twilight thought for a moment. "Then you are to call me Daddy. I'll be wearing a strap-on anyway."

"Yes, Daddy."

"Good little bitch boy."

The rest of the day proceeded as normal until right after dinner. They had been careful for long enough by now, surely. As Shining Armor finished the bottle of wine, Twilight opened up her duffel bag. Stripping away her clothing, she slid into her strap-on belt and secured the dildo she wanted to use on him first. Meanwhile, Shining Armor fastened his collar and leash, taking off his outerwear. He was wearing a lacy blue thong and a matching bra, accompanied by a blue and white pair of stockings.

"You look so cute and fuckable, Shiny," Twilight grinned, licking her lips. "Pull down those panties. I want to see that chastity cage."

Shining Armor fell to his knees, spread his legs, and slipped a thumb into his panties. With a gentle pull, Twilight could clearly see his limp dick trapped inside the small frame. She also caught a glimpse of what else was hiding in her brother's panties.

"Is that a vibrating butt plug?"

Shining Armor closed his legs. "I'll have you know that it's a vibrating butt plug dildo. Normal butt plugs feel like a plug. This one feels like a cock is inside you all the time."

Twilight could not stifle a laugh. "You like having a cock up your arse all day?"

Shining smiled. "Dou you want to replace it?"

"Not yet," chuckled Twilight with a malicious grin. "First, there's something I've always wanted to try since I first wore mom's strap-on." Grabbing her brother by the mane, she shoved her dildo in his face. "Suck me off, little bitch boy."

Shining Armor was shocked by this new display of dominance from his sister. Not that he didn't like it, of course. In fact, he loved it. Without any complaint, he began to tongue the rubber cock, showing off what he'd learned from years of sucking stallion dick.

While Twilight couldn't appreciate the tactile pleasure of swabbing her brother's throat, the power she felt that she held over him was making her wet. She couldn't wait to plow his tight arse later, but she first had to teach him his place. Or she would, had he not already known it. She began to thrust her hips forward as Shining's lips sealed around the dildo.

If you had told Shining Armor five years ago how much he would enjoy having his sister's shaft fucking his throat, he'd have punched you right in the face. If you said the same to him now, he'd kneel down and take your cock into his mouth, trying to pleasure you into keeping it a secret. Things certainly change when your wife has the most intense libido the world had ever seen.

Twilight finally pulled him off of her cock and out of his thoughts. "Ready to take me in your arse?"

Chapter the Ninth: Reversal

Shining Armor flopped onto the bed. They were once again in their parent's room. Even though the taboo nature of their relationship was a massive turn-on for both of them, it was so much more arousing in this room. Even though they knew they wouldn't be caught, the very nature of having sex where your parents could catch you was exciting.

While he was unable to have an erection, Shiny's cock was leaking seminal fluid as his sister climbed on top of him and pushed his wrists down. He loved being dominated by ponies smaller than him. He spread his legs and tilted his head back, waiting for her entry.

Alas, entry didn't come. Instead, she was poking at him. They both looked down between his legs, confused as to why she couldn't fit her cock down his hole. They both felt like idiots as Twilight reached down to pull out the plug he was still wearing. It was pretty tight in there, too. When it finally came loose, she could see into his gaping hole. It was at this moment that a new idea ran through her mind.

Placing her lips against his pucker, she dug her tongue up into his rectum, helping to lubricate him in the process. With every lick, her nose rubbed against his balls. Shining Armor was in ecstacy right now, with his sister tonguing his prostate and nuzzling his gonads. Twilight was also in a good place, as her nose was pervaded by the scent of her brother's testicles, and his cock juice was dripping down her forehead and cheeks.

It was time now for the main event. Grabbing Shining Armor by the ankles, she bent his legs back and pressed her dildo against his arsehole. By now, it was ready for her, and she slipped right in with almost no resistance. The room was filled with the sound of their hips slapping together and Shining Armor's feminine moans of pleasure.

"Yes, Daddy!" shouted Shiny. "Pound my pussy!"

"You want me to cum inside?" taunted Twilight, saliva dripping from her chin. "You wanna have my babies? You want to be the mother of my kids?"

"Yes! Breed me!"

"As you wish, momma." With a heavy slam, Twilight shoved her cock deep into her brother's arse, both of them spewing cum from their respective genitals. They didn't have the aphrodisiac to keep them going this time, and Twilight collapsed on the bed next to her brother. The two shared a tender kiss, and caught their breath.

After a short nap, they had another bottle of mead and returned to the bedroom. Before they returned to their activities, Twilight removed the dildo from her strap-on and fitted a fresh one in its place. This one was shaped like a werewolf cock. Shining Armor recognized it from his wife's collection. It was a very popular model.

After one more session of anal sex, the two fell asleep. The bulbous knot at the base, once inserted firmly into Shiny's arsehole, stayed inside of him the entire night.

When Twilight awoke the following morning, she looked down to see Shining Armor suckling at her cock head. "Good morning, momma."

Shining Armor took the dildo out of his mouth. "Good morning, Daddy. Do you like my dress?" He rolled off the bed and presented himself. He wore a yellow sundress, which Twilight recognized as one of their mother's.

"I do like," chuckled Twilight. "You're definitely taking to the role of Momma very well."

"Thanks, Daddy," smiled Shiny. "I picked out an outfit for you, too. It's sitting on the dresser." Shining Armor stood up and walked out of the room, swaying his arse as he went to make breakfast.

Twilight rolled out of bed and approached the dresser. The outfit her brother had picked out was one of their father's suits. This outfit was very deserving of the name Daddy. She put it on, not even bothering to remove the strap-on, as she was sure they'd be using it again after breakfast.

Shining Armor was not the best cook, so Twilight was pleasantly surprised when she came out of the bedroom to find that he had prepared a plate of raw fruit. While not the best breakfast, it would suffice. At least it had a lot of simple sugars involved, as they would need that for the day they were planning.

"How was breakfast, dearest?" asked Shining Armor, batting his eyelashes.

"You did a great job, honey," chuckled Twilight, enjoying the game they had just made. "I love you so much."

Shiny stood up and walked around the table, giving Twilight a peck on the cheek. "Part of me wishes we could go out on the town like this," he said, his face turning beet red. "It's too bad everyone around here knows us."

Twilight chuckled. "Yes, that would be a lot of fun, if we could... It really is too bad."

"I have an idea, my lovely," smiled Shiny, dropping down to his knees. "What if, once we return home, we try to find a place where no one would recognize us?"

"What a lovely idea," she smiled, shifting toward him. "And we could wear wigs and makeup, in case they take pictures."

"I like the idea of you wearing makeup," smiled Shiny as he unzipped his sister's pants and pulled out her cock. "Big blue kiss shaped stamps all over the inside of your thighs." He deepthroated the dildo that had been inside his arse all night, smiling as his master pet his mane.

"What a great idea," chuckled Twilight. She couldn't remember the last time she'd had this much fun. Whenever they played house as children, she had always been the mom, and her brother had always been the dad. Now, with their roles reversed, it was like looking at the world with brand new eyes. She liked being the man in charge. She liked being the top dog; the alpha male. It suited her just fine.

They went back to their parents bedroom, where they resumed their wild lovemaking. They were so very exhausted by the time they were supposed to have lunch that they skipped the meal, enjoying the entire afternoon talking to each other while roleplaying as their parents. As their dialogue was rather lewd, Twilight began to empathize with her parents regarding their collection of well used sex toys.

Chapter the Tenth: Together

It was now Monday morning, and they were both very sore from their almost constant sex. Twilight grunted as she sat up. "I think we should stop now, dearest."

"I agree," laughed Shining Armor, rolling off of the bed and onto the floor. "I don't think my arse has ever been this raw before."

Twilight took a long swig from a bottle of sports drink she had brought with her. She was running low on fluids. "Why don't you shower first, then? I'll start in on breakfast." With a quick peck on the lips, she left the room.

Shining Armor crawled to the bathroom and climbed into the shower. He was very glad that his parents had invested in a shower seat, as he was feeling the need for it by now. Running his hands over his body, he found all of the markings from the many sexual activities they'd performed. There were welts on his nipples from the clamps, small lacerations from the whip, and several contusions around his arse. They had overdone it this time. Next time, they'd have to slow down and focus on their relationship.

He felt so much better after his shower. The cold water really helped with the swelling and bruising. He felt absolutely refreshed and ready to resume his duties in the Crystal Empire. In his eyes, that made this a productive weekend. He dried himself off and made his way to the dining room, where his sister had breakfast ready.

"Wow," chuckled Twilight. "You certainly look refreshed."

"I feel it, too," chuckled Shiny, sitting down to his meal. "I feel like I could take on anything right now."

"How about you start with taking on breakfast, dear?"

After a lovely meal, it was Twilight's turn to shower. As the sound of running water echoed through the bedroom, Shining Armor stripped the sheets from the bed. Once again, they would need to wash everything quickly. He came back with a fresh set, glad that all of his parents' bedspreads were identical. As he was fluffing the pillows, he accidentally knocked over a small jewelry box on the nightstand.

Twilight picked that exact moment to come out of the bathroom. "What's that, Shiny?"

Shining Armor reached down and picked up the box. As he picked it up, the lid opened, revealing their parents' wedding rings. "Twily, look." The two sat down on the bed, just staring at the rings. "Why would they leave these behind?"

"Perhaps they're just worried about losing them?" posited Twilight. "I think I like that answer more than the alternative."

"I'm not so optimistic, Twily. This is very worrying to me."

Twilight began to rub her brother's back. "It'll be okay, Shiny. You're going to be just fine."

Shining Armor began to weep. Even though Twilight's assumption was absolutely correct, they couldn't be sure without asking, and they couldn't ask without revealing why they had been in the room in the first place. Twilight, not wanting her brother to feel the way he did, picked up their mother's wedding band.

"Shining Armor, son of Night Light and Twilight Velvet, I promise to you that no matter what happens, I will stay with you." She slid the ring onto his smallest finger. It was still too small to fit, but the symbolism was still there. "Through thick and through thin, in sickness and in health, for richer, for poorer, for better or worse, I make this solemn vow that I will always be there when you need me. You shall never be alone, for I will be with you. If not physically, then in spirit. We will be together until death takes us both." Lifting Shining Armor's chin, she met his lips with her own. It was a deeply passionate kiss. "I love you, Shiny."

Shining Armor sniffled. He felt much better now. Not to be outdone, he picked up his father's wedding band and slipped it onto his little sister's finger. It was much too large. "Twilight Sparkle, Daughter of Twilight Velvet and Night Light, with this ring comes the promise that I will always be your older brother, as well as your lover. I will never leave you completely alone. Whenever you call for me, I vow to come running, no matter the distance. Come rain, shine or fiery hail, You will always have me by your side, even if only in spirit. This will be so until both of us have died, and beyond." He returned his sister's kiss. "I love you, Twily. Now and forever."

Wrapping their arms around each other, tears began to flow down their cheeks. They were bonded to each other forever now. Not just in blood, but in marriage. Even if their parents were separating, which they weren't, Twilight and Shining Armor knew that they would be close to each other for all of eternity.

They returned the rings to the box, placing it lovingly on the nightstand. With a quick spray of odor eliminator, the room was clean and ready for their parents' return. With their toys and clothes all put away, they spent the rest of their time cuddling on the couch until their parents arrived.

"Hey, Shiny?" asked Twilight, looking up at her brother. "Last time we were here, you came inside of me."

"I did, yes."

"And yet, when I took a pregnancy test, it came back negative."

"I've been snipped, Twily. I can't produce children anymore." Shining Armor gently brushed his sister's mane aside. "For us, I'd say that's a good thing. If we had a baby, everypony would have questions. Where did it come from? Furthermore, think of the health problems it would have."

"Yeah, you're right. I'm not complaining, I was just curious."

Before long, their parents came home, and the siblings had to return to their façade.

"Good afternoon, kids," smiled Night Light. "Have fun?"

"We did," responded Twilight, running over and hugging her father. "Any time you want us to housesit for you again, you only need but to ask."

"We'll certainly keep you in mind," he chuckled. "Now, you two have a safe trip home."

Twilight and Shiny once again walked hand in hand to the train station. Even though they were going their separate ways, they had made their promises to each other. No matter how far apart they were, they would always come back to each other.

Epilogue: Forever

Sometimes, it's amazing how over a long period of time, some things never change. While many things do change as time goes on, the siblings' love for each other did not waver or falter throughout the five years they'd been married. However, there was one thing that had changed. Twilight and Shiny had come clean to Cadance about their relationship, and now Twilight held the second key to her brother's chastity cage, and was free to unlock him whenever they hooked up.

It was a cold afternoon in November when Twilight received a letter from her parents asking her to housesit for them again, with the help of her older brother. Of course she accepted, not wanting to pass up the opportunity to see Shining Armor again. She hopped on the train to Canterlot as the day arrived.

Once more, she found herself wrapped snugly in her brother's arms, her tongue wrapping around his. The key to his cage dangled on a chain around her neck, but that would have to wait for later. That was the grand finale.

Twilight moved to the kitchen in the late afternoon. Since she was the better cook, it was only fitting that she do the cooking. She had put together an intimate, romantic feast. A Salisbury steak with a side of roasted cauliflower. Gone were the days where they would drink wine with dinner. Now they had raspberry tea, as it was better for them in the long run.

"It all looks delicious, my love," smiled Shining Armor as he sat down at the table. He had changed into his mother's dress in the interim, and he looked absolutely ravishing. He had learned how to apply makeup, as well; He accented his facial features with great skill.

"Well, it's a special occasion, darling," responded Twilight, giving him a quick kiss before joining him at the table. "After all, it's not often that we find ourselves alone in this house. This is where we first discovered our feelings for each other, so it's a very special place."

"I know, Twily. I love that we're together now. It's refreshing to know that, no matter what, I can always call on you for help."

"And I you." Twilight raised her glass. "Here's to us. May we never drift apart again."

With a chuckle, Shining Armor raised his glass as well. After dinner, Twilight changed into one of her father's suits. While she did so, she found out what Shining Armor had done while she was cooking dinner. The bedroom was filled with candles, and a record player sat in the corner, ready to fill the room with the sound of whatever music they chose. The final piece of this puzzle came with the pair of rings that their parents had left on the nightstand again.

The record player started up as Shiny entered the room and lit up the candles. A slow cello and lyre melody began to play. Taking her brother by the hand, Twilight pulled him in and began swaying gently from side to side. While she was the one leading, he was much larger than her, and couldn't rest his head on her chest unless he dropped to his knees. As that would make dancing difficult, he opted to stay upright and let her rest her head on his chest.

In the low light of the candles, they looked deeply into each others eyes. There was a shine reflected back at them that had the two siblings falling in love all over again. They shared another kiss, never missing a beat as their feet moved around each other. their fingers wove between each other as they clasped each others hands.

Their dance ended with the end of the record. It was just as well, as Shining Armor had been backed against the bed. Leaning back, he lay down on the mattress, spreading his legs to allow his sister access to whatever she wanted. Slipping off his panties, she admired his chastity cage. It was time to use the key. With a click, the lock popped open, and as the cage slipped off of his shaft, she clasped it in her hand. His balls were absolutely turgid with his pent-up semen.

One long lick was all he needed to become fully erect. Not wanting to set him off too early, Twilight removed her pants and boxers, climbing up on top of her brother's face. "Before you burst, I'm going to need lubrication." Mashing her pelvis against his jaw, Twilight could feel his tongue lapping hungrily at her pussy.

"It never ceases to amaze me how sweet you taste, Twily," gasped Shining Armor when his sister allowed him to come up for air.

"Well, I do tend to keep myself nice and clean for you." Now dripping, Twilight lined up her vaginal entrance with the head of her brother's penis and slid down onto his meaty rod. They had done this so much by now that she was able to take his entire length in one go.

Soon, the music had been replaced by the sound of their hips slapping together. Shining Armor had learned long ago to keep his hands to himself, rather than try to help his sister along. She knew what she was doing. He just had to sit back and try to last. That was the troublesome part of the cage. He would increase his volume by a wide margin, but he would lose his stamina. In his prime, he used to be able to last for over an hour, but nowadays, he would struggle to reach five minutes before blowing his load.

True to form, he didn't last particularly long. Thankfully for Twilight, he had already warmed her up with his tongue, so when he released a powerful torrent of baby batter into her waiting womb, she was already close. As her internal structure squeezed around him, he couldn't hold back the flood.

Not bothering to take him out, Twilight lay down on her brother's chest, giving his neck a gentle kiss. With a flap of her wings, the candles were all blown out, and the room fell into darkness. Shining Armor nuzzled his sister. Their love, while mostly hidden away, was an unstoppable force. They would always be together, no matter what happened in the future.

"I love you, Twily."

"I love you, too Shiny."
