Flurry Heart has evidence of her Auntie Twilight's wrongdoing. She's willing to throw it all out, in exchange for a few favours.

Princess Twilight Sparkle and her Brother, Prince Shining Armor, have been having intercourse for several years now. Princess Cadance is well aware of this, and has both hosted and encouraged their activities, as doing so has brought them closer together. She's even joined in a few times to share her love with both of them.

However, unbeknownst to the three of them, they've had a spectator watching their every act together, and she's been taking lots of pictures. Flurry has collected several albums' worth of photographs of Twilight and Shining in the throes of ecstacy, and it is time they saw some use.

Now that Twilight's been clued in on what's been happening with Flurry Heart, she has to do everything her little Niece says, or suffer the humiliation and shame of having the photographs made public. But just how far is she willing to go to protect her brother and herself? Flurry is going to find out, that's for sure.

Contains: Incest, Blackmail, Gender Swap and Beastiality. For the purposes of this story, Flurry Heart is twenty-one years old.

Prologue: Games Mommies and Daddies Play

As Twilight set down her fork, she picked up her chased goblet and aerated her drink. "Your hospitality is something I look forward to every time I come up here," she smiled, a twinkle in her eye. She took a swallow of her drink. "Your food is pretty good, too."

"You're always welcome here, Twilight," chuckled Cadance, finishing her cake. "Every time you come up, Shiny's mood improves dramatically. I mean, it's no wonder, right? He loves his favourite sister about as much as I do."

Twilight let out her own giddy chuckle, which soon turned into a hint of worry. "Do you think we've kept him waiting too long? I mean, I'm all for building up the excitement, but it's been almost half an hour, and I've read that it feels even longer to the one tied up."

"Oh, he's fine, Twilight," assured Cadance, waving her hoof dismissively. "I once kept him waiting for over an hour because something came up. He was fit to burst, but he handled it like a champ. A short little half-hour like this, he should be up and ready, but still have some stamina left."

"As long as you're sure," nodded Twilight. "I just don't want to hurt him, that's all."

"Do you want to go see him now?" offered Cadance with a smile. "While he can wait a bit longer, there's nothing wrong with popping in a little early to see how he's doing."

With a nod, Twilight stood up. "I think I'm ready to see him now. I don't want to wait anymore."

The two walked back to Twilight's room, a large bedroom just off to the side of where Cadance and Shining slept. Despite Cadance's well-known debauchery and openness in her sexuality, Twilight didn't want the whole of Equestria to know what they were all doing behind closed doors. They were allowed to know that she supported family values, and that she led by example; coming to see her brother and sister-in-law at least every few months. She had no qualms against that being public knowledge.

As they arrived, Cadance gave her a hug, and they retired to their separate rooms. Unbeknownst to the general public, the two rooms had a secret door connecting them, hidden behind the Cadance de Milo painting on the wall. As Twilight was stripping down, the door swung open and Cadance walked through.

"You remembered to bring lube this time, right?"

"I made a checklist on edible paper with edible ink this time," smiled Twilight, quite proud of herself. "I brought strawberry kiwi and peanut butter banana. I want to compare the differences between them, if we have time."

"If we have time," agreed Cadance, opening Twilight's bag and shifting all of the clothing aside. As she reached the bottom compartment, she laughed. "Did you bring enough dildos? I can usually be taken care of by one or two, but you have what, eight?"

"There's only eight!?" gasped Twilight, rushing forward and rifling through the bag. She dumped out all of her toys and counted up her dildos. She breathed a sigh of relief as she found all nine of them. "Don't scare me like that, Cadance. I thought I'd dropped one somewhere. Do you know what would happen if someone found one of my strap-ons just laying around?"

"They'd think it was just a random dildo and throw it out, then wash their hands," answered Cadance. "Just like they do when they find mine. It's a waste of silicone, I'll admit, but at least they're not using them. That's why I told you not to put your name on them. You don't want some weirdo using it then giving it back, do you?"

Twilight shivered at the thought. "The reason I brought so many is because I wanted to try some of the new ones."

Cadance picked the new ones up. "The dog and dragon? Twilight, it doesn't matter what dick you have, he'll love having it in his arse, because he loves you. There's no need to impress him with fancy toys. Just push right on in and he'll be putty in your hands."

"Hopefully, he won't be that soft," joked Twilight.

As they laughed, they stepped back into the royal bedchamber. Shining Armor was tied to a chair, buck naked save for a bag over his head. His little soldier was standing at full attention, and firing off little drips of anticipation. He couldn't hear or see them, but his nose was very excitable. He followed the scent of Twilight as she moved around him, aggressively taking in her perfume.

"He's certainly excited to begin," chuckled Twilight, slipping into her straps. "I bet he can't wait."

"He's been talking about it all weekend," smiled Cadance, taking a spot behind her husband. "He really does love you very dearly."

With her tackle secure, Twilight kneeled in front of her brother. "I love him, too." In evidence of her statement, she placed her tongue at the base of his salty balls and dragged it along the underside of his turgid cock. By the time she reached the tip, he was ready to fire a great load into her open mouth. She savored the taste, swishing it back and forth in her cheeks before standing up and letting it drip into his open mouth. What stuck to her tongue was quickly gobbled up by Cadance as she undid the bindings.

As soon as he could use his arms again, he squirted some lube into his mouth, using it to apply a slick coating to both of Twilight's strap-ons. One was in the usual place around her hips, but a second one was up around her waist. That was a very odd configuration, and seemed to be custom-made. He didn't know what it was for, but he was willing to see where it was going.

As he finished up, Cadance grabbed him by the shoulders, pulling him over to the bed and up on top of her. As she kissed him, she used her hands to direct him into her vagina. There was never a need for lubrication with her; she was always wet. While what he wanted was Twilight, his wife was always a satisfying choice, and he began to thrust until she held his hips still.

Suddenly, he felt something big and firm pressing at his backside, He also felt Cadance tighten around him, as if somepony had shoved a cock up her arse. With a smile, he realized what the odd strap-on was for, and he relaxed his anal sphincter as Twilight pumped into both of their arses, filling them with glee and silicone.

Chapter the First: An Uninvited Guest.

As Shining came deep inside of Twilight's snatch, he collapsed to the bed. He was exhausted, but very satisfied. He didn't even have the energy to wish his sister a good night before he passed out. Pulling herself off of his shaft, Twilight helped Cadance rearrange his body so he would wake up more comfortably before snuggling up with each other, ready to go to sleep.

"I suppose, given the circumstances, it's a good thing Flurry was out with her friends tonight. I want to see her before I return home, but had she been around, I don't know if we could have done as much as we did tonight."

"Probably not," chuckled Cadance, rubbing Twilight's hips. "I know you love your niece very much, so if she's not back by daybreak, I'll send out a squad to collect her. I know she won't take a lot of convincing to come back. She's always looking forward to your visits."

With a smile, Twilight craned her neck to give Cadance a cummy kiss. "Good night, Cady."

"Good night, Twily."

As they drifted off to sleep in each other's arms, neither was aware of the open door leading out into the hallway. It wasn't wide open, merely cracked. There was enough clearance for somepony to spy on all three of them, and enough left over for a camera lens to slip through. The reason the door was open this far was because a camera had been slipped through, and it had taken several pictures of the trio. Now that they were done for the night, the camera had been removed from the room, and the perpetrator was furiously masturbating with her panties around her knees. She was smart enough to have sound-proofed to door, keeping the whole castle from hearing what she was watching, as well as keeping her elders and superiors from hearing her or anyponyelse that came along. It was, after all, an open hallway that was regularly patrolled by guards. She was almost finished now, just a few more seconds...

"Princess? What are you doing back so early?"

The guard had approached silently, and was standing right next to her by the time he spoke. This caused Flurry to jump, and as she did, she closed the door. She grabbed the guard by the jaw, shoving her sticky, wet fingers into his mouth.

"Do not sneak up on me like that," she commanded, angry. "If you saw me when you rounded the corner, you should have either continued on as planned, or made your presence known before approaching. What's wrong with you?"

"I hath ongy hongerig hy ou er keekig ing ong ouhr karenks," replied the guard, his tongue pinned down by Flurry's fingers.

"Don't worry about what I was doing," instructed Flurry. "Let's focus on what you should be doing. The way I see it, you have two choices in front of you. You can continue on your way and forget you saw me here, or you can escort me back to my room, eat me out, and then return to your guard duties and forget that you ever saw me here. Your choice."

The guard was silent and unmoving for a few moments, then lowered his upper lip, sucking on her fingers.

"Good choice," smiled Flurry slyly. She pulled her fingers from his mouth and picked up her camera, pulling up her panties in the interim. "If you do a good enough job, I might even ask your name..."

As the guard stumbled out of Flurry's bedroom, his left leg twitching a little bit, she stood in the doorway, watching him. "Back to your patrol, Dust," she smirked, seeing his discomfort. She'd made him wear her panties out, and they were both a size too small and soaking wet. She had kept his boxers.

As he disappeared around the bend, she closed the door. She had much left to do, especially if she was going to sleep tonight. She opened the camera and pulled out the film reel. She had a small darkroom set up in her bathroom cupboard. It was just a hobby, so she didn't have a room set up specifically for developing pictures. She was good enough at it, but clearly no expert. Still, one could look at the pictures and see what was going on clearly. She worked quickly, but made sure she had everything done right. Blurry photos or unclear pictures, while still usable, were not so effective at what she was planning to do.

As soon as she was done, she stored away the negatives in the usual place she kept them. She wanted them to remain hidden, just in case something happened to the photographs, and she had to make more. Those negatives were her insurance.

When the photos were done, she placed them into her hidden album, a large binder filled with a lot of images of raunchy things going on between ponies in bedrooms. Some of it she was keeping as her personal spank bank. These were the pictures she took the time to make sure were perfect. Some of them reflected the voyeuristic side of her collection, but others were ponies posing for her to take lewd photos. After all, what self-respecting stallion wouldn't want to drop his pants and show the princess just how big his cock was? What mare wouldn't want to show off how big, bouncy and soft her breasts were? Especially if Flurry was willing to do mouth and hand stuff after the photos.

Finally, after the binder was put away safely, it was time for her to flop down and go to bed. It was almost four in the morning, and she'd been up all night. Now it was time to sleep. Or nap, as it were. She would have to be awake soon, and if she could keep Twilight around one more night, she could begin her plan in earnest.

That made it all the more difficult when she was woken up at eight, after less than four hours of sleep. As she groggily dressed herself and dragged her body down to breakfast, she had to put on a giddy smile and a happy tone. "Good morning, Auntie Twilight!" she shouted, rushing forward to hug her favourite aunt. "I heard last night that you'd come into town, and I rushed back to say hello, but it seemed that you were already asleep."

Twilight smiled and hugged her niece. "You didn't think I'd leave without seeing how my favourite niece is doing, did you?

"Oh, please, aunt Twilight, can't you stay one more night? I would love to spend the day with you!"

Chapter the Second: Extortion

Twilight and Flurry shared a laugh as they walked up the castle steps. Twilight had afforded Flurry a nap early on in the day, as she knew what it was like to pull an all-nighter. Still, they had enough time to go out shopping with each other. It was deep into the evening by the time they returned to the castle.

"Ugh, Uni is such a pain," complained Flurry. "The studying wouldn't be so bad if it weren't for those tight deadlines."

"I always loved the deadlines," smirked Twilight. "They made it feel like a game to me. 'You have this long to put the whole thing together. Go!' It really helped push me forward."

"Well, it's not giving me any time to just relax and spend time with my friends. It's frustrating."

"It'll be over before you know it. And if you pay attention, you'll be all the better for it."

"I still think it's unnecessarily hard. Is there any way I can convince you to teach me how to better use my time?"

"You need only ask," smiled Twilight, wrapping her arm around Flurry's shoulder. "Let's go have a look at your homework, and see what I can do."

The two alicorns made their way up to Flurry's room. Twilight sat down at the desk that was in there, smoothed back her hair and lit up a candle to ensure that they would have plenty of light.

"A candlestick," smiled Flurry, locking the door. "How romantic. I can't tell you how many stallions I've had with the only light being a few candles scattered around the room."

Twilight blushed uncomfortably. She was not expecting to hear about her niece's sexual conquests. "I, uh... I can certainly understand why you might find that romantic, but..."

"It's great, actually," smiled Flurry, pulling out her binder of spank material and opening it up. She pointed to a younger stallion showing off his massive rod. "This guy here was the first to do that. He told me that my eyes sparkled in the candlelight."

Twilight pushed her hand forward to shield her eyes. "Yes, that's a beautiful penis, but perhaps we should--"

"And then this one showed me a real nice trick with the candles, asking me to drip hot wax all over her." She flipped ahead a few pages, displaying a picture of a mare with bright red wax dripping off her tits and pooling in her navel. The expression on her face was one of intense pleasure. "She also gave me my first set of nipple clamps. I speak from experience here; you do not want to try pinching your clitoris in that thing."

"I don't think I would make that mistake," assured Twilight, easing back a little while keeping her hand mostly between her eyes and the pictures.

"And then this one, oh..." She flipped to one which just looked like a mare masturbating with a rainbow dildo. "She spent ages melting down candles in a big pile, then shaved it down into a dildo and sealed it up so it wouldn't just snap off inside of her. Really clever use of what she had available. I finger myself all the time to this one."

"Flurry!" yelped Twilight, putting up her hands and closing her eyes. "I came up here to help you with your homework. I don't want to see these sort of pictures, nor do I want to think about you fingering yourself. Perhaps this is why you're having trouble focusing on your studies; because you're surrounded by all of these dirty pictures."

Flurry pushed out her lower lip and pouted. "I suppose you may be right. Okay, we'll put it away, but I just want to show you one more picture. Please, Aunt Twilight? I just want to show you my favourite, and then we don't have to look at any more."

Twilight took a few deep breaths. In through her nose, out through her mouth. She was already feeling a bit randy from the pictures she'd seen, and would need to employ Shining and Cadance's help relieving herself tonight. "One more. That's it. Then we really have to go back to studying."

Flurry nodded, moved several pages ahead, and beamed. "This is my favourite. Look how the candles make the vaginal discharge glisten off the stallion's cock. Simply beautiful reflections, don't you agree?"

Twilight could not pull her eyes away from the picture. Sure, it was a beautiful fuck stick. As Flurry said, the light danced off of it, giving it the illusion of motion despite the fact that it was a still image in an album. It was a massive cock, and the mare it was being plunged into looked to be in ecstacy. Twilight knew exactly how she felt.

"Flurry?"

"Yes, Auntie Twilight?" She grinned widely.

"Who gave you this picture?"

"I took it myself. The stallion and mare in this photograph have sex with each other all the time. They're so cute together. I photograph them all the time." In evidence of this, she flipped through the next several pages, displaying the many images of the two together. "You must really love your brother, Auntie Twilight."

Twilight flipped through page after page of her and Shining Armor in the throes of carnal bliss. It was very clear that they'd been doing this for a very long time, and that they had enjoyed every moment of it. If Cadance had been the one to present this to her, this would have been a very touching gift showing years of love between two passionate beings. From anypony that wasn't in the room with them, this was horrifying.

"Ah, but I promised we'd work on my studies after the pictures, didn't I?" smiled Flurry, closing the binder and tucking them away. "Shall we begin, Auntie?"

"How long have you known?"

"Five years. But don't worry, I've only been taking pictures for two and a half years. Now, I wanted to ask you--"

"Flurry, I need you to listen to me. Those pictures need to be destroyed. Not thrown in the trash, I need them destroyed. The other stallions and mares, you can keep, but the pictures of me and your dad need to be tossed into the fireplace."

"Of course, Auntie," smiled Flurry, taking one out and burning it in the candle's flame. "Of course, I still have the negatives, so I can just make another copy."

"You wouldn't..." Twilight's eyes went wide as her heart pounded in fear.

"Let's not worry about that right now," smiled Flurry slyly. "You were going to help me with my schoolwork. Now, we're studying law. What does 'extortion' mean?"

Chapter the Third: When an Invitation is Not Optional

Flurry moved her binder aside. "Well, that finishes my law exam preparation," she smiled. "And I know I'm going to pass my ethics exam. I'm the most ethical pony I know."

Twilight had to disagree with that statement. "You are blackmailing your aunt with dirty pictures you took without the permission of the subjects. I'd hardly call that ethical."

"But here's the rub," chuckled Flurry. "I know it's wrong, so I can tell the professor that doing so would be unethical. And that's what really matters."

Twilight groused. "Well, if you have nothing else that you need help studying for--"

"Oh, I never needed any help studying. That was just a ploy to bring you up here behind a closed door. I'm passing all of my classes, handily. I'm even tutoring some of the other students by performing sexual favours in exchange for correct answers. I bite on the wrong answers. I'm well ahead of the curve."

"I really don't want to know about that," reaffirmed Twilight.

"You will want to know these things," assured Flurry, moving over to the bed and slipping off her panties under her skirt. "I know you've studied a good many techniques, and can execute them beautifully. You're a very learned mare."

"Why in Equestria would I want to know what you like in bed?" asked Twilight, a disapproving scowl on her face. She had a feeling that she already knew the answer, but if Flurry wasn't going to force her hand, she would proceed as carefully as possible.

"Simple." She sat down and smoothed out her skirt. "Because you're going to be my next sexual partner. Oh, we're going to have all kinds of fun together, you and I."

"What makes you think I'd agree to that?"

Flurry looked up at the ceiling. "Contracts are a tricky business. There needs to be a consideration so that one party isn't just bullying the other by taking without giving back. If you were just going to be doing something for me with no reward for your contributions, that would be an unethical contract, and if you took it to any court in Equestria, they'd throw it out without even reviewing it. No, no, you must be compensated for your contributions.

"So, here's what we're going to do. Every time you and I have a bit of fun, I will destroy all copies of a photograph, including the negatives. Additionally, if you perform admirably, I may destroy more than one. The same applies for particularly powerful displays of passion. How does that sound?"

"I refuse," stated Twilight, plainly and bluntly. "I will not be a party to this."

"Such a shame," shrugged Flurry with a sigh. "I guess those pictures will have to be posted all over Equestria, in every newspaper and tabloid known to ponykind." Her eyes fell back down and locked with Twilight's. "And to think, it all could have been avoided if you simply agreed to do me a few small favours that you were already planning to do with daddy."

Neither party moved for the longest time, glaring into each other's eyes, struggling for dominance. Twilight may have been older, more respected, and have an otherwise clean record, but Flurry had the upper hand, and that hand was holding all the cards. After minutes of unflinching silence, Twilight lowered her head and sank down into her chair. "I want to discuss a few terms with you before we make any agreements."

"Of course you do," smiled Flurry. "And I will consider them accordingly. I may even accept them."

"First, I want you to stop taking pictures of me and your parents having sexual intercourse."

"No more pictures than I already have," agreed Flurry.

"Second, no exhibitionism. The point of this is to keep my bedroom life out of the papers. Having me walk naked down the street defeats the purpose. I'd be having you destroy one picture in exchange for hundreds that have no filter."

"It will all be behind closed doors."

"No telling any parties not involved what we're doing, either. No guards, friends, not even your parents. Nopony can know about this."

"No one will know what we're doing except the parties involved," Flurry nodded.

"And most importantly, no body modifying. I cannot walk out at the end of this deal with a tattoo across my chest branding me as a slut, and I must have all of my fingers intact and attached to my hands."

Flurry placed her hand gingerly over her chest. "Auntie Twilight, that hurts. I want to have fun with you, not mangle you. I promise you, I will not harm your body in any way. Any modifications will be temporary, like a spray-on hair dye. You simply take a shower, and you're good as new. It was never my intention to injure you."

Twilight still had a fair few qualms, but many of the ones she knew about could be brought up later. She didn't want to be there all night dividing up meticulous details. The faster she was done with the contract, the sooner she could go about fulfilling her end, and the sooner she could rest easy. "Okay."

"You agree to the terms, then?"

"I do," nodded Twilight. "And I expect you to adhere to your end. All copies and the negatives destroyed so that they can never be used again."

"You have my word," agreed Flurry, leaning back. "You know, Auntie, You have such a way with words. Your terms were very well-spoken and clear as a crystal pony."

Twilight raised her eyebrow. "Thank you?"

"You're so gifted with your tongue." Flurry pulled up her skirt and spread her legs. "Let's find out what else that tongue is good for, shall we?"

Twilight was taken aback. She had expected at least a night or two to gather her bearings. "Now?"

"Yes, now. I thought you'd like to see proof that I will hold up my end of the bargain? I'll burn them to ash, right in front of you. All I need is a guarantee that you'll hold up your end." She reached down and spread her lips open in invitation.

Twilight's gaze fell upon what lay before her. She could remember when Flurry was just a baby, and hadn't even said her first words. Now she was a woman, a fully-grown mare in her third year of college. Her off-pink flesh was mostly waxed smooth, with a small heart-shaped patch sitting just above her clitoris. It was purple with a blue swirl.

With a deep breath and trembling hands, Twilight lowered to her knees, leaned forward, and gently kissed the supple pink flesh.

Chapter the Fourth: A Taste of What's to Come

Fresh linen sheets, rubbed with lilac and rose, then stored in a cedar dresser with a sprig of rosemary between each layer. That was the scent that invaded Twilight's nostrils as her face sat in front of Flurry's pussy. It would have been lovely, if the circumstances leading into this closeness had been more amenable.

"Are you just going to stare at it all evening?" chuckled Flurry. "Staring isn't going to help you out of this deal. Why don't you give it a taste?"

"I was about to," lied Twilight. In truth, she was considering grabbing the pictures and bolting, and reporting the activity to her parents before she could make more copies. Unfortunately, she didn't know if Flurry had multiple copies handy right at this moment. A quick puff of smoke, and all of her spares could go directly to a local news outlet, and they'd be in circulation before Shining could make his way up here. No, that was not a viable option.

She pressed her lips forward, meeting Flurry's labia. As she pulled away, the remnants left a taste on her lips. She had to admit, Flurry kept herself clean. She was half expecting to end up eating a creampie that had been stewing for several hours, but no. She was all cleaned out and fresh as a spring breeze.

Twilight's tongue inched forward, pushing apart the lower lips until she could go no further. She began wiggling the tip of her tongue, stimulating Flurry's interior as best she could.

"Stop being lazy, Twilight," commanded Flurry, grabbing her aunt by the horn and pulling her in closer. "I know you can go deeper than that. You're supposed to be showing me a good time, not putting me to sleep."

With her face now mashed against Flurry's genitals, Twilight started moving her tongue faster. She was in the thick of it now, and that meant she had little choice. For a long period of time, she would have to do what Flurry commanded. She had grown out of taking orders long ago, but now she had to.

"That's much better," moaned Flurry. "You've very clearly done this before. More pressure, though. You really need to push at those walls, or you won't coax anything out of me."

Twilight slowed her movements down, pressing and wiggling her tongue at every nook and cranny in Flurry's vaginal canal. If she wanted pressure, Twilight was ready to lay it on her with all the force her tongue could exude.

With a smirk, Flurry began to gently caress Twilight's face, soon devolving into running her fingers through her aunt's mane. "Isn't that so much better?" she smiled. "That's a good girl, pleasing her new mistress. Showing me exactly how she handled her old mistress. Mother should have trained you to do a bit better, though."

As Flurry's words fell on her ears, Twilight came to a decision. It was a decision she would later come to regret, but hearing anything that insulted Cadance was more than enough to trigger a wellspring of defensive emotions that whipped up into a whirlwind of thoughtless actions. This was a personal attack, and Twilight was ready to return fire. She wrapped her hooves tightly around Flurry's thighs, pulled her hips in closer, and assaulted the interior walls of Flurry's marehood while her cheeks applied a rigorous suction to the exterior, her teeth pressing hard against her niece's clitoris.

Flurry was shocked, to say the least. Twilight's tongue was giving her a harder lashing than she'd ever received from anypony. Not even the lesbians she'd had intercourse with had such a knowledge on how to pleasure a mare's most sensitive areas. All she could muster was to lay back and moan.

Twilight wasn't done, either. With a flash of her horn, Flurry felt this massive rush of surprising pressure in her breasts, as Twilight's magic roughly massaged her perky flesh. She made sure to pay special attention to her nipples, pinching and twisting lightly, just as she did with Cadance all the time. If Flurry was going to insult her mother's taste and Twilight's technique, she would be made to eat her words.

Within minutes, Flurry was driven over the edge; clamping down on Twilight's tongue, her ankles wrapped around her aunt's neck, and a splash of her vaginal discharge filled Twilight's mouth. One would think this was the end of this session, but Twilight did not relent, driving Flurry to climax four more times before revving down.

Flurry was gasping for breath as Twilight stood up and wiped her mouth. "Your mother was very thorough. She even asked me to read up on the subject of cunnilingus, which I did. Anatomically speaking, I know where all of your weaknesses could lie, and after a few years of practice, I know how to find them."

Flurry couldn't respond at the moment. Her mind was floating around, bobbing in a sea of pleasure. It's not that she hadn't felt anything like this before, but that was a surprise, and it had been fully overwhelming. She took a few minutes to just breathe and come to grips with what had just happened. When she was ready, she pushed herself up. "I underestimated you, Auntie Twilight," she panted. "I knew you'd done this before, but... Wow."

"Now, we had a contract," reminded Twilight. "You are contractually obligated to destroy a photo and its negatives." She folded her arms from her chair by the desk.

Flurry's horn glowed as she stood up. "Just one?" She pulled three out of the album. "I believe the deal had a line stating that if you exceeded my expectations, I would increase the number destroyed. Do you really only want one gone?"

Twilight scrunched down her brow. "No, I want you destroy as many as possible. But I held up my end, and you have to destroy at least one now. And I'm going to watch to make sure."

As Flurry stood up and wobbled her way over to the desk, she brought up two copies of each, as well as the negatives. Twelve items in all. "You don't trust me? Me, your loving niece?" With a chuckle, she tossed them into the fireplace and lit it up with the candle. "Three down, nine hundred and ninety-seven to go. I'll be in Ponyville next week, we can talk more then. You can return to bed now. We don't want the guards talking, right?" Twilight stood up and walked out of the door as soon as she was sure the pictures were gone and Flurry unlocked the door. She took a deep breath as she walked out.

Chapter the Fifth: Malleable

"Come on, Auntie Twilight!" shouted Flurry, skipping merrily down the street. "We don't want to miss this!"

Twilight cautiously made her way down the street, a few steps behind Flurry, but keeping pace. For almost three weeks now, the two of them had been having intercourse every night they could. Twilight was very keen on the idea of being out of this contract as soon as possible. It wasn't necessarily the the fact that she and Flurry were having intercourse that bothered her, but rather the fact that she was being coerced into it. Given the choice, she might be willing, but as no choice was given, she just wanted to push through all of this. That's why she'd eaten Flurry out four times. That's why she let Flurry use her horn as a dildo. That's why she'd sucked on Flurry's toes, and that's why she was currently walking down the main thoroughfare of the Crystal Capital with a vibrating butt plug under her extra-absorbent panties. The sooner she was out of pictures, the sooner they could reach a nice, comfortable middle ground where they could both be happy.

"Where are we going, again?" asked Twilight, partially distracted. "I thought this was just supposed to be a walk?"

"Some friends of mine are having a small gathering at one of their houses. They're celebrating successfully passing their most recent test." Flurry raised her eyebrow. "I thought you, of all ponies, would be proud of a passed test."

"No, no, I'm glad they passed," corrected Twilight. "I was just wondering where we were going, that's all."

"It's just a small gathering. Five ponies, maximum."

"Oh, okay." Twilight breathed a sigh of relief. She could stand behind being seen supporting academics by praising a group of passing students. She had absolutely no problem with that notion.

"We're here," smiled Flurry, opening a gate and stepping into a small yard. It wasn't the nicest house, and not in the nicest neighborhood, but intelligence was not exclusively for the financially endowed. Plenty of children from low-income families were eager to learn so as to better themselves, so why not here, as well?

Flurry knocked at the door, and a stallion opened it a few seconds later. "Princess Flurry, glad you could make it," he smiled. "And Princess Twilight? What are you doing here?"

"I wanted to congratulate you. Flurry tells me you just passed an exam?"

The stallion looked confused for a moment. Then, Flurry winked at him. As realization flashed across his face, he nodded. "Right, okay. I wasn't expecting you, but sure. Come on in." He stepped out of the doorframe and let them pass. As Flurry made her way to the back, Twilight waited with the stallion.

"So, uh... What classes are you taking with Flurry?"

"Criminal law," answered the stallion, directing Twilight to a couch. "Some of the others know her from civil procedure, but their exam is two days away."

"Do you also take that class?"

"I'm a TA in that one. I took it early to help with a personal issue, and I'm still catching up. I'm not exactly the most well-off stallion in the Crystal Empire, but I'm hoping a law degree will help with that. I spend a lot of my free time either working or studying. It generates a lot of stress."

"Have you tried clerking?" suggested Twilight. "It's a great way to kill three birds with one stone. You can make some money, see the trade being plied firsthand, and the firm you work for might even hire you when you have a degree. If you really want to go into law, it's a great option."

"Do you know any nearby? I kind of have to stay around here."

"I'm sure you could find one."

"I'm glad to know that two princesses believe in me like you do," he smiled. "Would you care for a drink, Princess Twilight?"

"Not yet, but maybe later," smiled Twilight. "I don't exactly know how long weeeEEE--!!"

Without warning, the vibrating butt plug started spasming violently, causing Twilight to jump in surprise. She quickly looked to the hallway that Flurry had disappeared down, and saw the little minx waving the remote and beckoning for Twilight to come over.

"Is everything alright, Princess?" asked the stallion, concerned.

"I'm fine," assured Twilight. "Won't you excuse me for just a moment?" Without awaiting a response, Twilight took off down the hall, following Flurry into a room that she thought might be empty. Upon stepping in, however, she was met with two stallions stripped down completely. They were sitting on the side of an unmade bed, having just discarded the controllers for the video game they were playing. They had paused it, of course.

"Now that's interesting," smiled the jet black stallion with matching mane and cock. "I wasn't expecting two princesses today."

"What are you complaining for?" asked the white stallion with large brown spots and bright pink dick. "I, for one, welcome all princesses that want to brighten the day of lowly peasants such as we."

"Flurry, can I speak to you in the hallway?" Twilight seethed.

"Of course, Auntie," smiled Flurry evilly, stepping out of the room.

As the doors closed, Twilight turned to her niece. "This goes against our agreement!" she shout-whispered. "We agreed that nopony would know about this!"

"We agreed that only the parties involved would know about what we were doing. They don't know anything about our contract, except that they aren't allowed to take pictures or tell anypony. They know better than to incur my wrath."

"Why didn't you tell me about this?" demanded Twilight.

"Because when you asked, we were on a public street. Who knows who might have been watching, or even listening? Here, we know exactly who to come down on."

The stallion from the living room started down the hall, his boxers the only visible clothing he still had on. "I can't thank you enough for coming to help your niece reward us for a job well done, Princess Twilight. I always knew you were a good leader." He gently patted her shoulder with a smile, and disappeared into his bedroom.

"You know how I reward good students," smiled Flurry. "They worked really hard, and now their shafts are just as hard. They've earned a break from studying, and they have to go right back to school tomorrow. A clear mind will help them concentrate in class."

Twilight scowled, but knew she didn't have much room to argue. Flurry was right, she had to do this. She had agreed to it. She removed her top and returned to the bedroom. "Who's first?"

Chapter the Sixth: Uncertain Terms

Twilight slid down to her knees in the middle of the floor as the boys fought over who would be the first to take her mouth. She was actually hoping to cause enough of an upset between them that two of them would leave. To her credit, there was a bit of shoving and some arguing.

"I had the highest score of us," argued the black stallion. "That means I studied the hardest, and I deserve to go first."

"Bullshit!" shouted the spotted one. "I had the highest raise in grades; I deserve to go first!"

"I set all of this up, and it's in my house," argued the owner. "Surely that has to count for something?"

While it pained Twilight to see such disharmony in front of her as their friendship unraveled, she kept her mouth shut. A quick quip about how it was important to take turns, and she would save their friendship, but then they would all violate her against her will, and she would have little protection if she were to fight back. As far as they knew, she was here of her own volition, and saying otherwise would open up the contract, and it could become a public issue. This was the best she could do with her hands metaphorically tied.

"Boys, boys, boys," called Flurry, covering two of their mouths with her hands and pushing them down onto the bed. "There's no need to argue over which one of you will go first. It doesn't really matter who's first, as long as you all have a turn to relieve yourself, right?"

They nodded.

"You all worked your tails off, and you all deserve some appreciation for the effort you've put in. You've all agreed to meet up and share because of the limited time you have these days. Wouldn't it be more fun for you if you all took turns and had a wonderful time?"

They nodded again, small knowing smiles beginning to creep across their faces. Twilight had a small grin forming, herself. Flurry was easily solving an issue among friends and restoring harmony before her eyes. She was proud of her niece for a moment.

"Besides, Princess Twilight has three holes. She can take all of you at once."

There went Twilight's smile, and it took her pride with it. As the stallions looked back and forth at each other, they made a silent agreement amongst themselves. The owner rolled back, moving his head onto his pillow and firming up his cock again. The spotted one kneeled up near his shoulder, and the black one climbed off the bed.

"Well, Auntie?" smirked Flurry. She waved her hand, ushering her aunt onto the bed. Twilight stood up, brushed past Flurry and slipped out of her skirt, anal plug and panties. She'd hoped to decrease the number of cocks she would have to suck, but her plan had backfired, and she was now in a much worse scenario. Flurry's smug smirk wasn't helping, either.

As Twilight was about to lower herself onto the owner's rod, he quickly rifled through his bedside table's drawer, pulling out a bottle of lube and placing it in her hand. It was the peanut butter and banana one she'd bought for Shining. Not the same bottle, mind you, just the same brand. It had been the worse of the two, but it was better than going in dry.

"What a perfect gentleman," smiled Twilight, leaning forward to kiss his horn. "Making sure I'm not hurt." As he blushed up at her, she squirted some out into her hand, making sure to rub it into his skin thoroughly before she slid down his shaft. As she handed to bottle back to the stallion behind her, she rubbed the bit that remained on her hand over her arsehole, to help her prepare. As she began to move her hips, she felt the speckled pink cock rub against her cheek. She tried to take it into her mouth, but every minute shift of his hips had it moving around exponentially.

"Let me help you," offered the owner. Using his hands to hold her chest aloft, he moved her a little bit closer to his friend. "Now you can use your hands to direct him in."

In the back of her mind, Twilight knew he was only trying to be helpful to her, but she really wasn't happy to be pushed along on this unintended path. If she was really as willing as they had been told, she might come back and sleep with him again, as he had a very kind demeanor.

However, as she took the speckled stallion up to the medial ring, she was brought back to the reality of her situation. He was not quite as gentle, swaying his hips back and forth in short, shallow thrusts. He kept a loose grip on her mane for stability as she sucked, keeping her from being able to pull too far back.

Meanwhile, the black stallion was lubed up and ready to go. He needed no help being directed in, but a bit of lube on his right hand helped him to gauge how ready she was for him. First, his thumb went in, pulling her anus apart to test her tensile strength. He wanted her to be tight, but not so tight that he wouldn't fit. Then two fingers, then three. When he was sure she would have no trouble, he pressed his tip against her pucker, and shoved his way in.

The force applied was so great that Twilight slipped off of the owner entirely and deepthroated the spotted dick so completely that when he pulled back, some of his pubic hair was caught up between her teeth. He saw this as an invitation to go deeper than he ever had with Flurry, taking longer, slower thrusts. His cock was so large this far up that it forced her tongue out of her mouth. With every push, the swing of his balls would brush against her tongue, and she could taste that he'd been sitting in a pool of his own sweat all day.

Meanwhile, as the owner tried to reenter her pussy, a big pair of swinging black balls would smack his dick aside, and he would miss. He tried to make everything align properly, but everything was slippery and moving around with such freneticism, he couldn't keep ahold of anything. After several attempts, he gave up, opting to just finger her while playing with her breasts. He couldn't do much to push into her, so he decided that, at the very least, he'd keep her wet and happy.

Chapter the Seventh: Compensation

Twilight couldn't believe how rough these two were being with her body. Were they always this way with Flurry? She moved her eyes as best she could, but she couldn't see that far. She caught a glimpse of Flurry's shoes by the door, and that was about it. She couldn't hear her, either, as the stallions inside of her were being a bit raucous. The black one behind her, aside from the grunting, was making a slapping sound every time his hips struck her buttocks. She didn't much mind his noise, but the bespeckled stallion in her throat was talking in sentence fragments, as if he wanted to say something, but couldn't articulate it with any degree of certainty.

The only quiet one was the owner, having fallen out of her. With all of the action on top of him, he couldn't keep up, and had decided that he was just going to finger her, instead. He would be doing a good job, if she had the capacity to hold still, but no such luck.

"You can go a little harder," encouraged Flurry from behind Twilight's range of vision. "She's very durable."

Twilight's eyes went wide as those inside picked up speed. She already had no control of the situation, her hands just held onto the hips in front of her to keep her from falling over. She wasn't in any position to stop them. What's worse, the owner had lost his ability to finger her, and as a result. He now decided that the best course of action was to wrap his arms around her waist to keep her from sliding around even more.

How long had she been here? Thirty minutes? An hour? All afternoon into the evening? Twilight couldn't tell anymore. She'd lost track of time amidst the discomfort. Her only happiness at this point came from the fact that the pink cock in her throat was throbbing. She knew from her many sessions with her brother, and a few other stallions, that he was almost done.

"Take this, you WHORE!!" shouted the spotty stallion, the first complete sentence he'd said since entering her. As he exclaimed, he mashed his cock as far down her throat as he could, blocking her nasal passages with his abdomen. She couldn't breathe, and she couldn't push him off. She just had to hope he was quick. He fired off rope after thick rope down her throat. Most of it shot down her esophagus, but some was caught in her struggling trachea. She could only taste his balls, though.

After she slapped his hips several times, the stallion beneath her grabbed his tail and pulled him back a bit. "Give her some air, would you?" As the oxygen rushed back into her lungs, Twilight coughed up a big gob of cum that had made its way where it wasn't supposed to go. Her breathing was a bit raspy after that.

She didn't have much of a relief, either. The black cock in her arse started throbbing as well, and very soon, that erupted, too. He pulled out, spraying his seed all over her back, and into her mane. She was a mess, dripping cum out of her hair, her tail having been roughed up, and drooling out of her mouth and nose.

"I hope you had fun, boys," called Flurry, "because it's about time my auntie and I went home. We don't want a search party coming after us, do we?"

The two stallions that had just climaxed nodded and walked out of the room, grabbing their clothes off the floor. As Twilight picked herself up, she saw Flurry sitting in a mushroom chair in the corner. She'd been playing with a dildo while watching. If this had been Twilight's idea, Flurry would have helped out the owner, having been unable to please himself. That would have made for a more agreeable end for him.

She climbed out of bed, slipped the plug back up her arse, and began to dress herself as the remaining stallion wiped her down with a towel. It wasn't the best towel, and she'd certainly need a bath later, but the thought was what she valued. As she zipped up her skirt, she looked around at the floor. "Where are my panties?"

"We made a big stride today," smiled Flurry, moving to the fireplace in her bedroom after dinner. "All day with the plug, and eating dinner with cum in your mane and no panties? That's a good ten pictures right off the bat."

"What about your stallion friends?" asked Twilight. "Surely, servicing them all at once was worth another ten."

Flurry shook her head. "Not quite. I'm going to do something a little different with that. They'll rank your ability on a scale of one to ten. I'll add all those numbers up, divide by two, and round up. If they liked you, that's fifteen. If they didn't, that's just two."

"You owe me a new pair of panties, too."

"How was I supposed to know they'd be stolen?" asked Flurry, tossing the pictures into the fire. "I'll find out who took them tomorrow when I ask for their opinions. I'll even bring them back to you, if I can."

With a nod, Twilight walked out of the room. She hoped that Flurry's friends were pleased with what they'd done to her. She certainly hadn't tried to stop them. But something was nagging at the back of her mind.

She walked out of the castle and made her way back to the house and knocked on the door. It was just past sunset. When the door opened, the owner was wearing a towel and smelled like shower gel. "Princess Twilight?"

"May I come in?"

"Certainly." He stood aside once more and welcomed her across the threshold. This time, she led him over to the couch.

"I didn't have the chance to thank you earlier," she said, gesturing for him to sit. "You were easily the most well-behaved of the ponies here today, and it saddens me that you missed out."

"I mean, it's not the end of the world, but I--"

"Shhh..." Twilight pressed a finger to his lips, dropped down between his knees, and opened his towel. "You were a perfect gentleman; sharing your lube, holding me steady, making sure I didn't choke. Now I want you to know that I value stallions with good manners." He moaned and leaned back as she dragged her tongue up from his freshly washed balls up to the top of his clean tip. "I think it's about time you gave me that drink you offered," she giggled coquettishly.

Chapter the Eighth: A Change in Venue

"Oh, Auntie..." Twilight looked up from her writing to see Flurry standing at the entrance to the throne room. Thankfully, she was wearing clothes. "Mother and Father granted my request to come down to Ponyville for a few quick exchange classes. Won't my kind, loving aunt be willing to lend me a bedroom while I'm in town?"

The royal court looked up at Princess Twilight, waiting for her reply. If she had to deal with Flurry's powerful libido while she was here, she wanted her to be as close as possible. "You shall have the room right next to mine, where your mother and father usually stay when they come to visit," she decreed. "Close to the library for study, and close to me for intellectual discussion."

"How about a picture for the Ponyville Gazette, Princess?" asked a reporter, originally there to document a story of a royal guard captain. "This'll make a great exclusive."

Flurry rushed over to Twilight and hugged her aunt with a big, hammy smile. Twilight put on a contented smile as the picture was taken. After being given the thumbs up from the photographer, Flurry pulled away, but not before giving Twilight's buttock a firm pinch.

Twilight looked around to make sure nopony saw that. "So, what classes are you taking that brought you down here, Flurry?"

"Just a few quick ones. Shouldn't take me more than a month. It's just some field botany and practical chemistry. Recognizing plants and turning them into potions, that sort of thing."

"A month, you say?" Twilight was looking forward to clearing a lot of pictures from her record. "Did you make sure to bring everything you would need for your stay?"

"Don't worry, Aunt Twilight," smiled Flurry. "I double-checked everything." She sauntered toward the door. "I'm going to go bring everything up to my room and settle in. Come see me when you're done with court; I'd like a word with you in private."

Twilight returned to her work, but her mind was elsewhere. For the last six weeks, any interaction between her and Flurry had been very tame. Nothing particularly big had happened, and they were slowly chipping away at the pictures. In all honesty, Twilight was beginning to like Flurry's twice weekly visits. It just went to reinforce her thought that, had this all been optional, she'd have said yes.

She shook the thoughts out of her head and quickly returned to her duties. The faster she completed them, the sooner she could tend to Flurry's needs. There was a changing of guard armaments that needed to be approved for testing, a trade route that needed redirecting and a forest that had recently been subjected to a wave of parasitic insects that needed to be isolated to keep the outbreak from spreading.

She excused herself from the throne room when she was done and made her way up to Flurry's temporary bedroom. There was less of a boundary than there once was, so it wasn't unheard of for her to enter without knocking. "Flurry, I need to ta--"

"P-princess, I..." The guard that had been inside of Flurry stumbled backward and saluted, a clearly embarrassed look on his face.

"Already, Flurry?" chided Twilight, clicking her tongue. "You knew I was coming up. You couldn't have waited until after we talked?"

"You were taking forever. I needed something to pass the time."

Twilight looked at the clock. "It's only been twelve minutes."

"Well, you already caught us. No going back now." Flurry snapped her fingers.

"I don't think he's going to be ready anytime soon, Flurry."

Flurry rolled over and looked behind her. The guard looked torn, and he was completely flaccid. She grabbed his pants off the floor and tossed them in his face. "Back to your patrol, then."

As the guard hurriedly dressed and rushed out of the room, Twilight closed the door. "Now then, is there something important you wanted to discuss, or did you just call me up here to lick your toes again?"

"Well, since you offered..." Flurry spun around, removed her socks and shoes, and presented her foot to Twilight. Twilight kneeled down and started wiggling her tongue between her toes. "The reason I wanted an extended stay down here is to find the ingredients for, and to create, a very specific potion. One that should be easy enough to manufacture, given the price of it."

"Why don't you just buy one, then?" asked Twilight, going right back to Flurry's foot when her sentence was done.

"It has a few side effects when mixed with alcohol, so it's regulated until you've reached a certain age of maturity. It's mostly harmless on its own."

Twilight furrowed her brow. "How 'mostly harmless?'"

"Unless you drink it with alcohol, The worst side effect is that the temporary effects last longer than they're supposed to, unless you're allergic. But if you do mix it with alcohol, it develops some really nasty rashes that last a really long time. It's supposed to be agonizingly painful and very noticeable."

"You weren't planning on doing anything unsafe with that potion, were you?"

"Only its intended purpose," assured Flurry. "I can't buy it for another four years or so."

"That sounds like you can easily mess it up," groused Twilight. "If you're just doing this to make me pleasure you, I'll just buy the potion for you. If you really do want to make it, I have to insist that I watch every single step."

"Really?"

"Of course. I may be upset that you're blackmailing me bu--"

"We had a contract."

Twilight nodded. "I may be contractually obligated to let you use my body for your sexual pleasure, but that doesn't mean I'm going to let you hurt yourself, through negligence or ignorance. If you're going to do anything dangerous, I'd like to be sure that you're at least taking all of the necessary precautions."

A big grin spread across Flurry's face. "Why, Aunt Twilight... Even after all I've put you through, and what I still plan to put you through, you're still looking out for me? I'm touched." She leaned back as Twilight took several of her toes into her mouth. "I almost feel bad for what I'm going to do once I have the potion."

"What potion is this, exactly?" asked Twilight, her hands moving up to rub Flurry's thigh. "Should I be concerned?"

"Oh, it probably won't hurt you that much," smiled Flurry. "I'm going to be the one drinking it."

"Flurry..." Twilight stopped sucking. That's how serious she was. "What potion?"

Flurry leaned up and looked at her aunt. "Just a simple, ordinary gender reassignment potion."

Chapter the Ninth: Research and Development

Twilight returned to her castle as the sun began to set over the horizon. Her visit to Zecora had taken longer than she was expecting, but at least she could fly over the forest on her way back. While Twilight trusted her own skill in crafting potions of all varieties, she also knew that Zecora was far more experienced. That would make it far more likely that everything would go well.

Additionally, Zecora was one of the few ponies she could trust implicitly to keep this whole operation under wraps. She had to maintain a certain degree of candidness when interacting with her, but Zecora knew the value of discretion. She wouldn't go blabbing, and she had given Twilight the potion in an opaque brown paper bag with three staples to keep it shut until Twilight was ready to open it. There were very few ponies Twilight would share her secret with, but Zecora was definitely high on that list.

She rushed up to her bedroom, making sure the door was locked before opening the bag and placing the potion into a locking box. She would open it when the time was right, but not yet. First, she wanted to do a bit of research. Zecora had given her the same warnings that Flurry had, albeit in rhyming couplets. "Alcohol and this potion at the same time will clash; keep them separate to avoid the rash. Keep this information clear in your head, unless you want to wake in a hospital bed."

While she trusted that Zecora wouldn't skip out on warnings of danger, Twilight wanted to be absolutely certain that her niece was safe. She decided that it was time she did a bit of research on the potion for herself. If there was one thing Twilight did exceptionally well, it was research. She had a private library to prove it.

She made her way down there to do some looking into what to expect, and how to counteract the potion's effects, if she had to. When she arrived, she found the book missing, as well as a few more. Just when she was wondering who might have taken them, she heard a book close on the other side of a bookshelf. She peered around the corner, and saw Flurry sitting at her research table, a desk lamp illuminating the books that were missing from the shelves. "Flurry?"

"Hello, Aunt Twilight," answered Flurry, not bothering to look up. "I'll be here for a bit."

"I just came back from picking up the... thing you wanted." The library was an open room. Twilight couldn't be sure who was listening in.

"Thanks for that," replied Flurry. "I'll be up shortly to make use of it." Her voice was monotone, and her eyes never stopped scanning the pages. It was no wonder Flurry was doing so well with her studies, with how focused she seemed to be on the books she was reading. If this was how she studied regularly, it was easy to believe that Flurry was tutoring other students in her class.

"Have you finished with 'Perfectly Practical Potions and their Protective Properties when Percolated Precisely?'"

"Haven't started on it yet, actually," admitted Flurry, scooting it across the table. "Make it quick, I want to hit that one after I finish with 'Hundreds of Horrifying Herbs that are Harmful to Happy Homes,' and 'Many Minerals that May be Made into Magical Manifestations of Massive Might.'"

Twilight nodded and flipped open the book. She only had interest in one potion in particular; the one that she and Flurry would be using while she was here. She would be through quickly.

After another two hours, Flurry was done reading. She'd brought a notebook, and had scrawled in it the parts she needed to remember. "Well, that finishes 'Bizarrely Benign Beans that Brew into Basic Balms Both Beneficial and Baffling,'" she yawned. "What say we take a break from the studying for tonight and find something to eat? I'm going to be here for a whole month studying, and classes don't start for another three days. I'd say I have a pretty good headstart."

Twilight looked up at the clock. She made sure that it always chimed loudly in the library, but only at ten in the evening. She had to add that distraction, otherwise, she'd never be impelled to take care of her basic needs. She'd always be tired, hungry, dehydrated and smelly if she didn't put that clock in. Plus, she'd never be around to settle disputes or make the decisions the Equestrian citizens needed. They had about half an hour remaining.

"I suppose now's a good a time as any," she nodded, standing up with an armful of books. "Right after we put these away, how about we have a nice cheese and broccoli frittata?"

"Sounds tasty," smiled Flurry back, gathering up the rest of the books.

After their meal was finished, Flurry and Twilight made their way to their respective rooms. Their conversation at dinner today was just like it always had been until recently; an intelligent and respectful conversation between two knowledgeable mares that culminated in each of them finding a new viewpoint based on fresh information.

Today had been a good day for Twilight, all things considered. Flurry had already disposed of one photograph for the toe-sucking, they'd spoken as equals through dinner, and she'd even found the time for some studying with her niece. All in all, this had been pleasant.

That's when the secret door swung open. Twilight was more discreet about her sexual preferences than Shining and Cadance were, so she'd made her secret passage between the rooms far more difficult to figure out. In the Crystal Palace, the door was just a large painting. In the Castle of Friendship, one had to walk up to the bookshelf, rearrange three bookends and pull two books out, replacing them backwards, with the spines facing inside. If the order of the books was changed for any reason, or one of those two specific copies of the books were removed, there would be no way to turn the wall into a door.

"Good evening, Auntie," smiled Flurry, walking nonchalantly through the door. "Are you ready?"

"How did you open that door?" asked Twilight, befuddled.

"I saw Daddy open it, once," came Flurry's simple answer. She strode over, sat down on the bed, and spread her legs to show that she'd already discarded her panties. "Now then, we've both checked out everything there is to know about that potion, and you say you've gathered it from a reliable source. All precautions have been met. I'm ready to drink it."

Chapter the Tenth: Growth

Flurry tilted the bottle back over her head and drank three mouthfuls of the potion. There was no serving size for this. The more you drank, the longer the effects would last. The whole bottle would generally last ten to fourteen hours, depending on how the recipient's body reacted.

"So, how long do we have to wait for it to take effect?" asked Flurry. "I mean, I'm okay with a little wait, but I'd like to know how long."

"Give it time," said Twilight, her eyes on Flurry's labia. "I've seen potions that only took seconds, and others that take hours. I don't think this one will take more than thirty minutes."

"Ugh..." Flurry flopped back onto Twilight's bed. "I was really excited about this. Why does it have to take so long?"

"It's not so bad," smiled Twilight, patting Flurry's knee. "We just have to find a way to kill thirty minutes. We could read a book, talk to each other, play a game of cribbage or--"

"I can think of something fun, too," grinned Flurry. "You've been eyeing my vagina since I sat down. Why don't you taste it?"

Twilight raised an eyebrow. "Doesn't that seem a little bit common at this point? You have me do that all the time."

"I know. But this time, it makes sense. I'm going to have you suck my dick as soon as it comes out, and this way, you'll already be in the correct position."

Twilight shrugged. Flurry had a valid point. If Twilight were to wait in this chair for everything to happen, it would be very boring, and she'd want to be ready right away. Granted, the time it took to stand up and kneel down wasn't long at all, but a card game would need to be put away.

Twilight dropped to her knees and licked her fingers. She'd had enough time to practice on Flurry's twat that she knew exactly how to please her at this point, and how to prolong her pleasure. It all began with a kiss, then a lick, then a bit of sucking on the flesh as her tongue probed her vagina. That was just enough to make her wet. After that, she would focus on fingering her, her tongue mostly focused on the outside.

Flurry could feel a warmth spreading throughout her body. It started in her chest, as her breasts began to shrink. There wasn't a whole lot there to begin with, but she was upset to see it go. Then there was the heat in her gut. She could feel something happening, and she was pretty sure it was the potions effects about to come into play. However, neither of them were expecting what happened next.

"Ow!" Interjected Twilight. Flurry's testicles had dropped out of her vagina, and her clit had suddenly grown into a massive cock. She was a very well-endowed princess. Or prince, as it was. Regardless of title, the member had shot up and appeared so suddenly that it had jabbed Twilight in the eye. "Watch what you're doing with that. It's not as easily controlled as you might think."

Flurry wiggled his hips, watching how his cock jiggled. "I have a swingy thingy," he chuckled. He reached down and ran his hands over it, moaning as he did so. "I can see why they love this. I love this." As he began to firm up, he stepped up onto his feet and whapped his turgid length against Twilight's cheek. "I know I was already in a position of power over you, but spanking your cheek with my dick is really giving me a tasty power trip."

Twilight was amazed at how completely the potion had worked. Not only had it changed Flurry's body, it had changed his mane and given him facial hair. He was now sporting a thick, wavy set of locks and big, bushy mutton chops. What was most beautiful, though, was the scent. Flurry had showered before going to the library, and had smelled sweet and flowery just a moment ago. Now, her balls were leaking a powerful, masculine musk that just made Twilight want to submit.

"Well?" asked Flurry, pressing the head of her cock against the underside of Twilight's nose. "Start sucking, Princess. We're on a timeline."

Twilight wanted to make sure Flurry experienced to the full benefits of being a stallion in Princess Twilight's bed. She started off strong, relaxing her jaw and throat with a spell she'd learned from Cadance, and sliding the whole length of Flurry's shaft down her throat in one gulp. The newly appointed prince couldn't take the sensation and fired off prematurely with a yelp, stumbling back onto the bed.

After a few deep breaths, Flurry centered himself. "Well, I guess I can't ever blame a stallion for popping off early anymore," he groused. "Not with how long I lasted."

"You had a powerful opponent," smiled Twilight, nuzzling Flurry's balls and taking in a big whiff. "You thought I has going to go easy on you? We've only just begun." Once more, Twilight's mouth was wrapped around Flurry's massive meat popsicle. She pleasured herself with her left hand, using her right to fondle Flurry's nutsack. If Flurry was out of bed again before sunrise, it would be a wobbly trip to the toilet. Otherwise, he would be either on his back as he was now, or on his knees.

Flurry wasn't on the same wavelength, though. After he was hard again, he stood up, braced his legs in a more stable stance, grabbed his aunt by the ears, and rhythmically began thrusting his hips forward and backward with a force that he didn't think he had. He was in control of Twilight, not the other way around, and he would use her body for what he wanted. If she was pleased by the end of the night, that was good, but it wasn't necessary. She was his toy, and he would treat her as such.

To his surprise, Twilight was into it. Unable to keep a hand on Flurry's balls without slowing his movement, she focused on fingering herself from both ends, letting the pleasure rise to her chest, where it came out of her mouth in the form of a moan. That vibration in her throat transferred into Flurry's cock, adding to the stroking action.

Flurry was no pushover this time. He managed to hold out for a good fifteen minutes before he held Twilight's head down, firing a heavy load down into her stomach. When she came up for air, she was sporting a big, goofy grin. "What's next, my charming Prince Flurry?"

Chapter the Eleventh: Exhaustive Action

As Flurry fell back onto the bed, Twilight stood up. She hadn't reached any degree of climax tonight, and Flurry had been over the edge twice. Three times, counting what happened during daylight hours. That would not do.

"I'm not done with you," grinned Twilight, tackling him to the bed and pinning down his shoulders. "You're not going to leave me high and dry this time." She brought over a gyrating dildo and shoved it up Flurry's arse. Within a moment, Flurry's cock was rock hard again and ready to keep going, despite his mind still being washed over with pleasure.

Twilight took the initiative, slipping her snatch around the flared tip and devouring the shaft in one dip. Sure, it was big, but she was so hot and bothered at this point that her body just made adjustments to itself to let him in as far as he could go. several pain receptors were shut off, membranes stretched out, and organs rearranged themselves to make room.

Twilight took a minute or two to feel the member inside of her. It wasn't the biggest she'd ever had, but it was still bigger than average. All of it was brand new hardware, and it had never been touched by anypony else. There wasn't really anything like a "new cock smell," and even if there were, colts would be jumped right away for their fresh pheromones. But there was something magical about this untouched skin that sent waves of excitement through Twilight's mind. It was a very unique experience that was seldom spoken of, and it was due some credit.

As Flurry's mind began to clear, he grabbed Twilight by the hips and began to shift his groin, bouncing her slowly up and down on his dick. Being inside of this warm, dripping wet hole was divine, and every light movement was met with exquisite returns.

It wasn't long before the two were slapping their hips against each other in tandem, without any need for cues from the other. It didn't matter who was in charge anymore. They were working together to drive their partner to climax. Twilight's fingernails dug into Flurry's shoulders and chest, and Flurry had a firm grip on Twilight's breasts. True, he'd had his own pair mere hours ago, and he'd played with Twilight's several times, but there was something different this time. In the past, he would play with them while Twilight was sucking off a stallion, and the moans she let out were exciting. This time, however, merely the act of squeezing their supple flesh and feeling them wrap around his fingers was bringing him joy.

Twilight could feel her end drawing near, and with one powerful slam, she clamped down on his length, so tightly that he couldn't possibly pull out, and drenched him in her vaginal juices, her interior musculature quivering against his shaft, almost drawing him further in. She'd been denied climax all night, and now that she'd had it, she was ready to collapse.

Flurry wasn't having it, though. He'd been brought so close by that, and the gyrating dildo had slipped out minutes ago. He had to finish. He grabbed Twilight by the shoulders, mashed her face into the pillows, and yanked her tail into the air to expose her flank. He'd been in almost all of her holes today. There was only one left. He lined himself up with her arsehole and plunged in as deep as he could go.

Twilight was glad she'd just cum all over Flurry's cock, as that was the only lubrication he'd gone in with. She no longer had control of her legs, and the only thing her hands could do was to grip the underside of the headboard to keep herself from colliding with the wall. She was fucked, both figuratively and literally, until Flurry blew his load inside her gaping tailhole. That wasn't a very long wait.

Having cum three times in the span of two hours, All of Flurry's activity caught up with him at once, and he collapsed on top of Twilight, worn out, dehydrated, and unable to form a single cognizant thought. He passed out a moment later, drooling over Twilight's mane.

Twilight, quite pleased with herself, used magic to wrap Flurry's arms around her middle, did not pull Flurry's cock out of her arse, rolled them over into a spooning position, and pulled the blanket up over them both. She was exhausted, herself, but she managed to gently drift away into dreamland.

Flurry awoke the next morning back to normal. She wasn't sure if her mind was still a little bit fuzzy, but she could almost swear that her breasts were bigger than they had been yesterday. She reached down between her legs, but the cock and balls were long gone. They'd disappeared in the middle of the night.

She heard the door open and close in her bedroom, then Twilight came through the hidden door with a big smile on her face. "Good morning, Flurry. Sleep well?"

"Very very well," affirmed Flurry. "You're certainly chipper this morning."

"You lost a lot of fluids last night," explained Twilight, pulling a cart full of food into view. "We have to replenish those before you return to your studies."

"My studies?" in her groggy state, Flurry wasn't quite sure what Twilight was talking about.

"You wanted to learn how to make that potion," reminded Twilight. "And you're going to learn how to do it the right way. Not only are you going to study those books cover to cover, you'll also be guided by a very smart tutor who's going to make sure you do everything correctly."

"Thanks, but I don't really need a tu--"

"No objections. This is an important potion, and you're going to be brewing it several more times. You need to understand it inside and out, because when you drink it again, it needs to be perfect." Twilight poured a tall glass of grapefruit juice and handed it to Flurry. "That was your main goal of coming down here, wasn't it? You wanted to learn how to make that potion so you could use it before you turned twenty-five?"

"Well, yeah, but I thought that--"

"Not another word," shushed Twilight. "You don't have to thank me, just finish your breakfast, make sure to drink plenty of juice, water, and coffee, and meet me in the library when you're done." Before Flurry could call out again, Twilight was out of the room. She looked over her breakfast, a rather nice spread. She wasn't sure what had flipped this switch in Twilight's mind, but she certainly wasn't going to complain.

Chapter the Twelfth: The Crystal Prince

Twilight was in a good mood today. She was on a train to the Crystal Empire. After Flurry had finished her classes with flying colours, she'd returned to the Crystal Empire and to her parents, and Twilight hadn't heard anything since. That is, until yesterday. Shining had sent her an invitation back to the Crystal Palace. She was definitely looking forward to spending time with her brother again.

As the train arrived, she was met with the familiar sights of the Crystal Empire. Everything seemed as it should be. Citizens bowed on the street as she passed, and continued about their days. The guards were patrolling, and not doing much more than that, meaning that there probably weren't any huge problems in the Empire of late. That meant that she wasn't being called to fix something, and this really was just a visit.

She hurried along to the palace, stopping along the way for a small punnet of crystal berries to snack on at the market. It was good for public relations if the visiting princess was supportive of local markets and farms, and even better if the food was as sweet and juicy as these crystal berries. The only downside was the temporary stains it left on her teeth.

The punnet was just about empty when she arrived in the throne room. She was expecting to be met by either Shining or Cadance, but neither was around. Instead, upon the throne sat Flurry, leaning back with her feet up. She was wearing Shining's royal uniform that he was supposed to wear on diplomatic missions. He often refused, and just wore his cuirass, instead. In the event that something went wrong, he was prepared, He always kept his blade sheathed in his room, though. It was bad form to bring a sword to a peace talk.

"Good morning, my dearest aunt," called Flurry. "How are we this fine morning?"

"Confused," answered Twilight. "Where are your parents? I wanted to talk to them, first."

"They're out of town for the weekend," came Flurry's answer as she lifted a hip flask to her lips, taking a large gulp. "A few quiet days in Saddle Arabia, essentially renewing a contract for allowing our trade route through their lands. Really more of a formality than anything else."

"If Shiny was going to be out of town, why did he call me here?"

"Oh, I did that."

Twilight raised her eyebrow. "Why?"

"I wanted to see you again. Don't you love your niece?"

"Of course I do," answered Twilight. "If you had asked me to come up for a visit, you know I would have done so right away. As for my question, let me clarify; Why did you feel the need to send the message as your father?"

"I thought that you might be more excited for that. Besides, he's coming back tomorrow. You'll have his cock deep in your cunt tomorrow night if you stay."

Twilight's eyes went wide and frantically scanned the room. There were no guards, thankfully, but Twilight scowled at Flurry. "That's not something you should speak about in such an open area, Flurry. What if someone heard you?"

"I soundproofed the room as soon as you came in, and the guards were sent away when I heard you were coming. That's also when I went to put on daddy's uniform. We won't be disturbed unless there's an emergency, and if there is, we'll have bigger problems than somepony walking in on us."

"Walking in on us?"

"Yes." Flurry smiled widely. "You and I are going to have some fun before Mommy and Daddy come back."

Twilight raised her eyebrow again. "What kind of fun?"

As if in response to her question, Flurry's beard grew out again, her mane changed how it flowed over her shoulders, her chest widened and flattened, and a considerable bulge tried to press its way out of her pants. It wasn't the explosive growth that had hit the first time, but a gradual, more natural change. "You're going to suck my dick, right here and now."

Twilight sighed. "Flurry, this is exhibitionism. That's against my contract, and you know it."

"Nopony will see if you do it quickly. I told the guards not to disturb us for two hours after your arrival. It's been ten minutes since you walked in, I drank an hour's worth of potion, and the longer you take, the more likely it is that somepony will come in. Contract terms satisfied."

With a lot of apprehension, Twilight came forward and kneeled in front of Flurry. "This is the only time I'm doing this. It's an unnecessary risk. From now on, please try to pick more concealed locations. I want to minimize witnesses."

"Duly noted. Now start sucking."

Twilight unzipped Flurry's pants and fished out his cock and balls, careful not to catch any of his hair in the zipper's teeth. It had only been a few weeks, but she had missed this particular section of her niece's anatomy. She drew her tongue along its length, taking the tip into her mouth.

"That's right, Auntie. Just pretend that it's daddy's cock."

While the comment was unnecessary, as Twilight was already in the process of sucking it as she had several times before, this was actually good advice. She didn't mind swallowing Flurry's dick, but the simple act of pretending it was her brother's made it easier to forgive. If she was sucking Shiny's fuck stick, she had a choice in the matter, and he would make sure her wish to keep this quiet was upheld. Even if he couldn't do that, he would ensure that she was kept out of the spotlights, and he would take all the shame.

She could imagine, just now, some paparazzo snapping a picture of her blowing her brother. He'd send a contingent of guards to say she was somewhere else at the time, and it was actually Cadance leading a changeling in a disguise trying to spice up their lovemaking with some very convincing roleplaying. Cadance would, of course, back this up, and a changeling would be smuggled in to be part of the controversy. Twilight would, of course, be outwardly against the idea that some changeling was disguised as her for the purposes of having a sexual thrill, but she would, after a few days, publicly forgive her brother for having such a kink, as she genuinely wanted him to be happy. After that, they could go back to fucking, they'd just have to be a bit more careful.

She wiped a tear from her eye as she came up for air. "I love you, Shiny."

Chapter the Thirteenth: Return to Form

After Twilight's pretend session in the throne room, she returned to the public eyes to talk to the populace at large, and to do a bit of casual shopping. A new crystal dress with accessories to match were coming back home with her at the end of this trip.

With the sounding of the train whistle, she rushed to the station. She couldn't wait to see Shining and Cadance again. As she arrived, she saw Shining step off the train into the platform. "Shiny!" she waved.

Shining's face suddenly turned to a smile. "Twily!" he ran forward and hugged her. "I didn't know you'd be coming. I'd have told you that I was busy."

"Flurry requested a book from my private library. I was just bringing it up to her, and figured I'd just wait for you and Cadance."

"Yeah, about that..." Shining scratched the back of his neck. "Cadance stayed behind for a few extra days to help them deal with a problem they were having. She won't be back until Wednesday."

"Why didn't you stay, too?"

"I trust my wife. She's tougher than she looks. Besides, I promised Flurry that I'd come back on time. I love my wife, but I love my daughter, too."

"You're a good father."

"And you're a great aunt."

As they turned and walked back to the palace, Twilight smiled at the wordplay. "I didn't know Flurry had kids." She had her mane tousled for that.

Twilight stuck around for dinner, a delicious corn chowder. She kicked of both of her shoes off to lock toes with the two entities flirting with her under the table. Flurry was being a bit more aggressive, but above the table, she was very quiet, and anypony that wasn't under the tablecloth would be unable to tell that this was just a normal dinner.

After their meal, Shining of course offered Twilight her usual guest room, which she gladly accepted. When night fell, the secret doors opened, and the siblings embraced each other once more, drawn into a deep, passionate kiss. As they came apart, they gazed deeply into each others' eyes.

"I really missed this," smiled Twilight, lighting up a few candles with her horn. "You and me, alone together."

"It's not that Cady's interfering was really such a bad thing," nodded Shining, turning on the gramophone and adding a record. "Honestly, she just wants us to be happy. You can't fault her for that."

"No, but it's nice to have some alone time once in a while." As the sounds of a piano and upright bass filled the air, she pressed her cheek against his chest. "How long has it been since it was just you and me?"

"A few years," answered Shining, wrapping his arm around her shoulder and gently swaying to the music. "But you're right. All of the crazy, frenetic sex in the world means nothing if we can't just sit back and enjoy each other's company."

"So you want to have less sex?"

"Let's not be hasty. I love having sex with you, Twilight. I have since the first time we did it sober. I just wish we had more time to dance like this."

Twilight couldn't help but to smile. He was a big softy at heart, helping her to fall in love with him all those years ago. This was one reason why she could never stay mad at him.

As the electric guitar slammed its way into the somber jazz piece, and a trumpet began to sound alongside it, Twilight held her brother tight. She never wanted to let go. She wanted to stay in his arms as long as she could. She was his. As the song faded away into the ticking of a clock, she craned her neck up and kissed him again. "I love you, Shining Armor."

"And I love my Twily." They stood there for a moment before Shining began moving them toward the bed. He lay Twilight down on her back, and gingerly began unbuttoning her shirt with his teeth. It was a slow, deliberate process, but his commitment to it made Twilight quiver in anticipation. She could feel his breath on her chest as they stared into each other's eyes. She loved it. It felt so intimate, so caring, and so gentle. In response, she grabbed the key to his zipper between her toes and slipped it down the teeth, then undid the button in the same manner.

They'd done this a great many times before, and soon, without any involvement from their hands, they were almost undressed. Shining's member had been pushed through the slit in the front of his boxers, and Twilight was only in her panties and bra. It was time for the piece de resistance. Shining positioned his head between Twilight's outstretched thighs, licked a few times against her wet cotton panties, then sucked the fabric into his mouth, gripped it gently between his teeth, and pulled them down to her ankles, and then off. Both were hot and bothered, both were ready to jump each other, but as Shining's lips came back up to meet hers, there was a knock at the door.

"Auntie Twilight? Are you still awake?"

Twilight and Shining looked at each other. Clearly, neither wanted to stop, but they couldn't just leave Flurry out there. With a soft sigh, Twilight kissed Shining on the cheek. "Blindfold yourself and wait on the bed. I'll be back as soon as I can." She rushed back to her room, hurriedly threw on a pair of panties and a long, conservative nightgown, closed the secret door, and opened the hallway door to let Flurry in. "What's wrong?"

Flurry sent a burst of magic into the room. "Now, that was sexy."

"What was?"

Flurry pushed her way in and closed the door. "The way he pulled down your panties with his teeth. I haven't seen that move in a long time."

"What did I say about watching us?" scowled Twilight.

"You said not to take any more pictures," smirked Flurry, innocently. "And I wasn't taking any pictures. I was watching. There's a difference."

"What do you want, Flurry?"

"Well, I was going to tell you go easy on him because he's wearing a butt plug, but since you blindfolded him, I have something else come up that I need to talk about."

"I spotted the plug, actually. He kept his heels up the entire time we danced. Dead giveaway."

Flurry's face contorted into a smile that made Twilight very nervous. "Yeah, it was pretty obvious. But now, we're going to have a slight change in how the night goes."

Chapter the Fourteenth: Interruption

The door swung open and Twilight returned to her brother in his room. He was wearing his blindfold, sitting on the corner of the bed, waiting patiently for her return. Or perhaps a bit impatiently, judging by his throbbing erection. "All taken care of?" he asked, hopeful that they would not be disturbed again, and also hopeful that his daughter was satisfied.

"Pretty much," came Twilight's answer. "At any rate, I don't imagine there will be any more interruptions tonight." She placed her hands on Shining's chest and pushed him back onto the bed, kissing him the whole way down. She pulled him up the bed with magic, locking his wrists into the cuffs extending out from the headboard and sliding a magic-blocking ring over his horn. "We can't have you peeking, can we?"

"No, we can't have that," smiled Shining, well aware of how powerful sensory deprivation could be. Shutting out his sight meant that he could feel every tiny movement against his skin. "What do you have in mind tonight, Twily?"

"Something very special." She climbed off of him and slid off the bed. "I forgot something in my room, though. I'll be right back."

Shining waited in anticipation as Twilight moved over to the door, opening it up again. With a nod, she stood aside, and flurry walked in. She'd stripped down and had been lubricating herself during their foreplay. As part of the ruse, Flurry would need to remain completely silent. As much as Twilight wanted to feel her brother ravaging her insides, she couldn't say no to forty pictures being destroyed. Flurry had offered twenty originally, but Twilight had managed to double it in negotiation. It wasn't quite how much she valued quality time with Shining, but she could always just invite him personally to join her for dinner another time.

"Are you ready?" asked Twilight as Flurry climbed on top of her father, throwing her voice a bit to make it seem as if she was the one climbing on him.

"I'm positively dripping," came Shining's response.

Flurry slowly slid down onto Shining's cock. As a bit of collateral, and in order to make sure her audio cues were on time, Twilight would be feeling everything Flurry did. It was like being given a copy instead of the real thing. Still, it was realistic enough that she could almost believe it if she closed her eyes. Almost.

"You're squeezing me tighter than you normally do, Twilight. Is everything alright?"

"Everything's fine, Shiny," replied Twilight, craning her neck to kiss her brother's lips. "I guess I've just been a little stressed lately, is all. I should loosen up in a little bit." She turned and scowled at Flurry. This was all meant to be done in secret, and Flurry had just stumbled. If Twilight could have spoken candidly, she would have told her niece to tread carefully, but all she could muster was a disappointed face.

Flurry began to slide up and down on Shining's shaft, imitating what she was sure he would like from years of reconnaissance. It felt really dirty just being in bed with him like this, without him knowing it was her. It was dirty, and she was loving every second.

"Twilight, you're not acting like yourself. Seriously, what's wrong?"

"I'm fine, Shining."

"No, you're not. Just stop for a minute and talk to me. You're acting very strange tonight, and I'd like to help you."

Whether Flurry liked it or not, She was clearly not Twilight, and would need to be coached through it. She gave Twilight a pleading look, then motioned with her hands the number fifty. With a nod, Twilight moved her hands onto Flurry's hips and pushed her all the way down, as if to take a sitting position on Shining's balls.

"It's because of what Flurry said to me in the other room," explained Twilight. "I know I said she'd probably be fine, but part of me is wondering if I didn't just half-arse my explanation just to hurry back here. What if I gave her the wrong idea? What if I didn't give her the most recent developments, and she fails the test because of that? What if she fails the test and doesn't like me any more? What if--"

"Twilight, hold on a second." Shining took a deep breath. "Do you have any idea how much Flurry loves you? She talks about you coming to visit all the time. She wants to visit you all the time. It's actually really annoying sometimes."

Flurry pouted, but couldn't risk much more than that.

"She's not going to dislike you for something so small as that. Moreover, she's a smart girl. She'll figure it out, and you should know that. She'll find the right answer, just like you would."

A tear ran down Twilight's cheek. Her story had been a complete lie, and her brother had come up with the exact right words to say. "I love you, Shining." She leaned in and kissed him again. "I don't know why I ever worry with you around."

"I love you, too, Twily. Feeling better now?"

Twilight nodded, but since he couldn't se that, she grabbed ahold of Flurry's hips with her magic and began shifting her up and down, back and forth, in exactly the way she knew he liked. She could feel his movements inside of her through Flurry's spell, and it was good. Better than when Flurry was in control, a fact that Flurry took immediate notice of. There were no more complaints from Shining about differences in technique, and Twilight was really having a good time, despite the fact that there was a pony separating her and her brother.

The night went on in much the expected way, ending with Shining firing off a heavy load into his daughter's womb. This would have been more concerning news, but they both had their own ways of preventing pregnancies. There was almost no way that they could conceive, and even if they did, there were extra measures in place to keep it from becoming a big deal. Twilight even managed to reach her own climax right before her brother.

With a wave of Twilight's hoof, Flurry climbed off her father and left the room as silently as possible, while Twilight curled up next to her brother. She hadn't had the night of carnal debauchery she'd been looking forward to all evening, but it wasn't awful. In the end, it had been a little bit fun, and very productive. Her brother had been right, earlier. The frenetic sex was good, but the dancing and cuddling were her favourite parts.

Chapter the Fifteenth: Revision

"There they go, as promised." It was the middle of the morning after Twilight had spent the night with Shining Armor, and Flurry had just dumped a grand total of seventy pictures, their negatives, and multiple copies into her fireplace. "Forty for the act, ten more for saving the situation, and another twenty for making it more fun. That's quite a dent you just made. We're about halfway through. Very solid work, Twilight. I'll have to become better at haggling if I want these to last a year."

"I want to make a revision to the contract," stated Twilight plainly, watching the pictures burn. At the top of the pile and last to catch was the time Shining had pinned her against the wall. A fun memory that she wanted to remember, but didn't want shared. "There are a few things I'm not happy with that I need to bring up."

"Do you not like the fun we've been having, Auntie Twilight?" teased Flurry. "Dou you want to annul the agreement? Or perhaps you want me to turn the pictures over to you instead of burning them?"

"I want you to burn them all right now."

Flurry laughed. "Why in Equestria would I do a silly thing like that?"

"You made a big mistake last night, Flurry. Nopony comes between Shiny and I. Those that do find themselves incurring the wrath of an angry princess."

"The wrath of an angry princess? I think I can manage."

In response, Twilight reached into her pocketbook and pulled out a sheet of paper, handing it off to Flurry. "There was nothing in our contract about me taking pictures, was there?"

Flurry took the sheet of paper, and her eyebrows raised. The picture, while very clearly a copy made hastily, was of her, riding her father's dick while he was blindfolded and chained up. He was grunting at that moment, so his face looked to be in pain, while Flurry was unbound and looked to be in intense pleasure. Even if it wasn't the best example of what really happened, it looked to be a pretty damning picture.

"Now comes the question of what to do with this," continued Twilight. "If the press took both your evidence and mine, it seems as if my relationship with my brother, while upsetting, is entirely consensual. Your relationship with your father, on the other hand, looks like he doesn't have a choice in the matter. Or, who cares about the press? I could take this to your parents. That would be a more biased approach, because they're already aware and in approval of my time with Shiny. What to do, what to do..."

A grin crept across Flurry's face. "You conniving bitch." She burst out laughing. "I must admit, I didn't think you had the balls to face me in my own game. Well done, aunt Twilight. That was a commendable attempt. Very well, let's hear your revision."

Twilight smiled as she sat down. "It's simple, really. You destroy your evidence; that is, the negatives and all copies, and I destroy all of mine."

"That's all?"

"That's all."

Flurry shrugged. "You weren't kidding when you said the new terms were simple."

"It is in this way that I hope we can find some measure of even ground between us. I don't want this to do any more damage to our non-sexual relationship. I don't want to be bitter towards you anymore."

Flurry leaned against the wall and thought about it. "I think I can cut you some kind of deal. First off, I'm not accepting those terms as they currently are. I have several hundred pictures, and you have just the one, so the disposal is not quite equal, is it?"

"Actually, I have over a dozen," admitted Twilight. "And I'm willing to destroy them all if you do the same."

"I might, but there is a caveat."

"What caveat? What's staying your hand?"

Flurry had to choose her words very carefully. "Think back to the main point of the contract. I would destroy my pictures in exchange for sexual favours."

"Yes, and we've been doing that, but now I--"

"I will destroy the rest as you ask, but there is a provision in the contract that I would be granted a sexual favour in exchange for doing so. I will destroy everything, and you will destroy everything, but right before that, you and I will have one last, super-kinky hurrah. This will be the last sex we will have in regards to this contract, as we will both be out of material evidence against each other. How does that sound?"

Twilight considered the offer. Flurry had used tricky language before to subvert their contract, so she had to be careful. "Just one session, and it cannot last for more than twelve hours. On top of that, all other protective claims I had originally still apply."

Flurry nodded. "Just one session lasting no longer than twelve hours, starting the exact moment one of us touches the other, but only at my command. You can't just pat my shoulder on the way out the door and wait twelve hours. I will say when we are to begin, and after that, any touch begins the twelve hour count, and that includes the use of magic."

"Any sexual conduct before that command is issued, and you forfeit the ability to issue the command," added Twilight. "You can't have me eat you out tonight and expect me to honor this revision next weekend."

There was silence in the room as both parties considered their position. For once, Twilight held some degree of control in this discussion, and she wasn't about to balk. She had to stand firm here.

"Okay," came Flurry's eventual response. "You've done a pretty good job so far, and you've been positively sporting no matter what I've thrown at you. I will agree to one more session in exchange for all evidence, both ways, destroyed. No lasting damage, no more salacious bedroom pictures, and we'll be far from everypony. Nopony else will know."

Twilight smiled. "Then we are in agreement?"

"We are. I will begin setting up our very special alone time, and I will let you know when it's ready."

With both parties now in agreement, Twilight made her way out of Flurry's room, down the hall to her own, packed up her bags, and returned to her own castle in Ponyville. She had no idea what Flurry was planning for her, and at this point, she didn't care. What mattered was that she'd negotiated her way out of her contract, and things would soon return to normal.

Chapter the Sixteenth: Open Range

Twilight's shoes touched down on the dirt road ten kilometres from Whinnyapolis. She was unsure why Flurry wanted to meet her here, of all places. It looked to just be a small farm, run by a maximum of three ponies. There was a decently-sized farmhouse with a netted porch, a large shed with large farming equipment poking out of the door, and a big red barn. Surrounding the property on all four sides was an outline of fir trees mixed with a few mulberry trees, making it difficult to see the fields surrounding them.

"Are you sure this is the right address?" she asked her driver. "I think we may be at the wrong location."

"I think this is correct," answered the driver, pulling out a map. "I followed the instructions to the letter. The only way we're at the wrong location is if the map we were given is wrong."

Twilight glanced at the map. They'd taken the correct turns, in the correct order, at about the correct intervals. This should have been the right place. She flew up into the air, did a quick comparison, then returned to the carriage. "No, you're right. This is the place we were supposed to go." She looked around again. "But why would Flurry call me all the way out here?"

The porch door to the farmhouse swung open, and a stallion in a straw hat, flannel shirt, overalls and black boots approached. "Are you Princess Flurry Heart?" he asked. "Everything's ready for your visit with your aunt."

"No, no," corrected Twilight. "I'm Flurry's aunt, Princess Twilight Sparkle. I was supposed to be meeting her out here. By your confusion, I'm guessing she hasn't arrived yet. What exactly did she have you set up?"

The farmer looked from Twilight to her driver, then to the pair of armed guards. He began to sweat. "She told me that I wasn't supposed to tell anypony about it. Is it... Is it okay to talk with so many ears present?"

Twilight shook her head. "Just answer me one question: Is it safe, what she asked you to do?"

"As far as I know. I mean, she just wanted to use the house and barn, and the most dangerous thing in the barn is the pitchfork I use to feed the ox. As for the house, I suppose you could do some damage with the cast iron skillet, but unless you're misusing the stuff, it should all be safe." There was a brief pause, then he remembered to add a final warning. "Stay out of the machine shed, though. A lot of that stuff is dangerous if you don't use it properly. I should go lock that up real quick."

As he rushed off to the shed, Twilight returned to her carriage and saw Flurry's coming around the bend on its way down the dirt road. She took a deep breath as Flurry stepped out on arrival and hugged her aunt. "Good to see you again. Are you ready for our relaxing weekend retreat?"

Twilight was sure this weekend would not be nearly as relaxing as indicated, but decided to play along, regardless. "You bet I am. I can't wait to have a calm, quiet weekend with my favourite niece."

"Are you Princess Flurry Heart?" asked the farmer, rushing back to them after locking up the heavy equipment.

"I am," replied Flurry. "Is everything in order as I specified?"

"Yes ma'am," he replied, offering his keys. "I'll be back Sunday night. You have the house and the barn. Enjoy your time here at my farm."

"Thank you," smiled Flurry. "My carriage driver will take you wherever you need to go. You just enjoy a nice weekend off."

As the farmer took off in Flurry's carriage with a guard escort, Twilight sent her own away to return on Sunday night. Once they were alone, the two walked into the house.

"So, what do you think of the location, Twilight?" asked Flurry, spinning around to face her aunt.

"I'd like to know why you picked this spot."

"It's isolated. The nearest pony is more that two miles away. Nopony will hear a thing out here."

Twilight scowled. "We have soundproofing spells. We could have stayed at the castle and nopony would hear us."

"There are more reasons," answered Flurry. "Open skies, fresh air, nopony to come between us, just to name a few. Besides, it's rustic. I had the guy buy a set of sheets just for us that I'm going to bring back home with me as a souvenir."

Twilight sighed and looked around the house. It reminded her a lot of Applejack's house, if a bit more rough around the edges. It was only a single story in height, with a very easy to navigate layout. There was a kitchen, dining room, enclosed porch, bedroom, and a bathroom. It was all very open and simple. Twilight had always enjoyed this sort of home; there wasn't a lot to them, and you could make them whatever you needed them to be.

The bed was very well-used, and sagging in the middle. The sheets were new, as Flurry had indicated, but the mattress had probably been unmoved for years. "This is your idea of a relaxing hideaway?"

"If it makes you feel any better, I don't plan on ravaging you in the bed," offered Flurry. "Not unless you want to after your twelve hours are up."

Twilight turned around to face her niece. "You're going to start the timer right away?"

"Not right away," chuckled Flurry. "Let's go out to the barn and I'll show you my intentions."

Back through the house and into the yard, the duo made their way to the barn. It had been recently built, a common thing this far out. Every few decades, it was customary to pull the whole structure down and rebuild it to make sure it didn't come down on accident. The door slid open with a big push from Flurry, and they trotted inside.

Right in the middle of the barn was a device that Twilight had seen in books several times, but never in person. The front had a pillory with a few straps, clearly not from the original design, as the device seemed old, but the pillory section was brand new with shiny new bolts holding it in place.

In the next instant, Twilight was being bent over with magic and pushed into the pillory, where her head and hands were held in place. A ring slipped over and clamped down on her horn to restrict her magic. As Flurry flipped up Twilight's skirt, she whispered, "Twelve hours."

Chapter the Eighteenth: Menagerie

Flurry slipped a ring gag into Twilight's mouth, keeping her jaw open for what was to come. If Twilight wanted to hurry along the punishment, she would need to double her speed. Additionally, she was given a blindfold. This would not only make the feelings more powerful, but she would be unprepared for and surprised by what would go into her mouth and pussy.

The first thing into her mouth was hardly a surprise, though. With a bit of coaxing from Flurry, The dog leaped up and began humping Twilight's mouth. Now that she had a taste of his cock, it was surprisingly clean. Sure, he smelled awful, but once the taste of cum washed off on her tongue, what was left beneath tasted like anypony else after a wash with an unscented soap. He smelled awful, but there was nothing wrong with the taste.

Then came something she did not expect. Another dog mounted her and began humping at her backside. There were two dogs, and they were claiming her as their own. This morning, she had been a princess. Now, she was no more than a cumdump for a pair of horny dogs.

The first dog, a spotty one, slammed into her again. This time, the knot went in on the first try, squeezing just past the ring gag and swelling up inside her mouth. As he turned and dismounted, his testicles pulled up and rested on her nose. The smell was foul. Worse yet, being this deep in her mouth, her tongue was pressed up against his sheathe, and that tasted as bad as his balls smelled. It was sour, like urine, and tasted like he had been sitting in mud. At the very least, due to his short dick, she could still breathe through her nose as he shot spurt after drippy spurt down her throat.

The dog behind her fired off next, slipping his knot into her much easier than the first had. Twilight had already been stretched out, and while upset at the situation, knew that there was nothing she could do unless something came along to break the contract, and Flurry had taken several precautions to prevent that. Unless one of these dogs scratched her, she was stuck with them for the next eleven hours, and they seemed to be exceptionally friendly, despite their lust. Their claws were probably either padded by Flurry or trimmed down by the farmer.

Both dogs eventually pulled free when their knots retracted. She wondered how long it would be until they would mount her again as they came around and licked out her mouth through the ring gag. She could do nothing to stop them from running their slobbery tongues along the interior of her cheeks and breathing their rancid breath into her nose and throat. She imagined their tails wagging wildly as they seemed to be very eager to keep her happy. If only they knew...

She felt the cold chill of a flat nose running over her thighs, leaving a trail of slimy mucous all over her arse. This was followed by cloven hooves on her back, and a brand new penis entering her already stretched-out hole. Again, it didn't seen to be very long, and it was also very thin, but it wriggled around like a worm as it tested her gaping hole.

Just when she thought this might be easy, the creature lunged forward, and his penis shot deep into her, coiling around her cervix and probing the hole into her womb. Twilight let out a yelp as the shock caused her to squirm, but settled down quickly and did her best to hold her composure. She'd never been fucked by a pig before, and while she was very grossed out by the feeling, she couldn't stop him. She just had to endure the feeling and let them work their game.

This pig was a real stud. He lasted a lot longer than the dogs had. The dogs had only lasted five minutes at the maximum, with maybe ten minutes of tugging on their knots. The pig spent a good fifteen minutes just warming up, then let out his semen in several long squirts that must have lasted another ten. Just when it was starting to feel good, he pulled off, oinking and grunting as he trotted away.

Twilight panted in her bonds. She still had ten more hours to go. She didn't know if she would make it, but she would try. If there was one thing she knew, it was that she would make it out of this in the end. She was almost done.

She felt something press against her lips; something hard and wet. "Drink up," commanded Flurry. She did as she was told, and was relieved to find that it was a water skin. It washed out her mouth and rehydrated her. "You've done well. I might let you out a few hours early."

"Hahng hou hichhechh," said Twilight through the gag.

"Oh, don't thank me yet," chuckled Flurry. "You've only been down there for an hour so far. You have eleven to go. Nine if I decide to show mercy."

Twilight gulped hard. Her perception of time was slowing down. At current, it seemed as if she'd interpret the twelve hours as being twenty-four. She was strong of will, but did she really have the ability to go that long? What if the punishment turned even worse, and she felt as if she was there for days, with every second feeling like a whole minute as it ticked away slower and slower? She shivered at the thought.

"I've also asked your pal Fluttershy to hook me up with something special," added Flurry. "It took a lot of convincing, but I think it was worth it. After that, a little bit of mind clouding was all it took to make it do what I want. Doesn't work on ponies, but beasts are another story. So don't hold it against the animals out here on the farm. They don't exactly know what they're doing, only that it makes them feel good."

Twilight felt Flurry's fingers in her arse, spreading it open as wide as it would go and slipping a tube inside. It was a hard tube, and it kept her wide open as flurry flushed out her colon and filled it with water. Twilight had no idea what Flurry was planning with this. She knew it was some kind of punishment, and it was certainly uncomfortable to have an arse filled with cold water. Then came a long tendril slipping along her colon walls, covered in tiny suction cups.

Chapter the Nineteenth: Parade

Twilight squirmed and wriggled around, trying to find a comfortable position to lie in. Every time she thought she'd found a spot to rest, she'd have to shift again in a moment's time, as she wasn't the one deciding the actions inside of her arse. That was the domain of the octopus Flurry had coaxed up there. Its many squirming tentacles explored her colon as if it were some sort of cave. She couldn't even push it out, as Flurry had plugged up the hole.

"Now, let me give you the same assurances I gave Fluttershy. Clyde is not able to move any further than a really long cock would reach. You can also rest assured that the cold water filtering in and out through that plug will keep him healthy and unharmed. After all, he's not the one being punished."

Twilight squeezed her eyes closed, hoping that at some point, the cold water would numb her to the feeling of the tentacles slipping past each other, or that she would grow accustomed to the feeling. She didn't care which, but having all of those slick tendrils pressing everywhere and the suction cups creating vacuum seals against her colon walls was one of the most degrading things she'd ever felt.

"We're not done yet," called Flurry, patting Twilight's arse again. This was not really a surprise to Twilight, after all, the punishment had only been an hour so far, though it was quickly seeming to turn to three. "On with the next one."

Whatever the next one was, it was heavy and had paws. He also had some very soft fur on his underside, and he was very warm. As his cock entered her cunt, she noticed that it wasn't large in any sense. Not particularly wide, and also very short. Just when she thought this might not be so bad, he pulled back. His dick was covered in backward barbs that dug into her pussy flesh, already sore from the dogs and pig. Every tiny thrust felt like being stabbed by a bunch of tiny needles. This couldn't be harmless. She had to be accruing some kind of damage from this.

Twilight shouted out in pain through the gag, begging Flurry to stop this. All that happened was that she came over to stroke Twilight's mane. "You're fine," she said, patting her cheek. "It'll hurt for an hour or two, but that's it. No lasting damage, remember?"

Twilight couldn't see, and couldn't do anything to stop it. She didn't know if Flurry was telling her the truth, or if she might actually be bleeding. At the very least, she could feel the rapid, shallow thrusts, and if she had any puncture wounds, they wouldn't be that deep.

The spurt when he came was not high in volume. There wasn't much she could focus on aside from the octopus in her arse and the large cat in her snatch, so any small difference was something of note. He wasn't deep inside, but Twilight could feel his every movement. If it hadn't been for the barbs hooking into her skin, this might not have been so bad. As he pulled out, though, those spines dug in and scratched her. She cried out, only to be silenced by Flurry's cock sliding into her open mouth.

This was actually very comforting, as it was at least familiar, and not as painful. As Twilight moaned into her niece's dick, she felt herself calming and relaxing. She was now properly humiliated, and had learned her lesson. No more fighting with mistress Flurry. The only way she could think to convey this message was to be a good little sex slave and suck her mistress off without complaint.

She heard the faint twinkle of magic, and felt the device she was secured to moving. Its arms were coming up and locking in place over the top of her. That meant that the smaller animals could no longer mount her, as they were too short. For a moment, she thanked her mistress for her mercy and generosity. Then she heard a loud moo from behind her. A cow? The whole device shifted as he mounted it. Twilight could feel his engorged cock against her thigh. He was as big as...

...An ox. Twilight remembered the farmer talking about feeding an ox, so that must have been what was behind her. She struggled and pulled against her bonds in a panic, causing Flurry to grip her by the cheeks. "Don't fight it, Twilight. The best thing you can do for yourself right now is relax. He's coming in, whether you want him to or not, just like all of the others."

Twilight was terrified as the device shifted again as the big bull dropped back down onto his hooves, shifting her hips with his snout. As he climbed back up on the mount, she tried her best to relax, but every instinct in her brain had her muscles tensing up and bracing herself. She was shaking as the pointed tip pressed against her labia.

It pushed inside her despite her body rejecting it. It was massive, somewhere between the dogs' shafts and their knots, but even longer than the pig's. It actually managed to stretch out her cervix a bit as it scrunched up inside of her. She'd never felt anything like this before, and on top of all of the damages done by the other animals, she was sure something would tear. There was no way she was unharmed at this point, but with her mouth occupied, her hands still bound by her neck, and her horn sealed off, there was no way to tell how extensive the damage was.

The bovid shaft thrust in and out of her as best the bull could manage. His pleased mooing easily drowned out Twilight's muffled yelling as her blindfold was soaked with tears. Deep in the recesses of her mind, she cursed herself. She had wanted this weekend with Flurry to be an unforgettable experience. Now, she was sure she would never forget it. She found herself wishing it would have been for a different reason.

The bull's release couldn't come quick enough. He effectively shot his hot load of semen directly into Twilight's womb, overfilling it to the point where the residual cum from the other animals was washed out with enough force to spray his balls. She felt so full that she would have vomited if Flurry wasn't cumming down her throat. She felt broken, and she had little hope that she would ever be repaired. She wondered to herself if she would ever want to fuck again.

Chapter the Twentieth: Cavalcade

Panting and full of bull cum, Twilight lowered her head. She didn't know how much more she could stomach. She felt like crap, and she was sure it was going to turn worse. To her surprise, Flurry pulled off her blindfold, lifting her chin to lock eyes with her.

"How does that feel?" she asked, not bothering to remove the gag. Twilight pleaded with her eyes to end this here and now. "Are you ever going to undermine one of our agreements again?" Twilight shook her head frantically. "Good." Flurry walked behind Twilight. "In that case, I'll go easy on you. I'll give you half an hour to stew, alone with your own thoughts. This will count among your twelve hours, so you won't be pausing your time while I'm out."

The barn door opened and closed, and Twilight heard the lock click into place. She didn't know if there were any animals still waiting behind her, but at least she didn't have to worry about other ponies walking in on her. She could rest easy, at least for a little while, knowing that she was mostly safe. At worst, Fluttershy could ask the animals what happened and put things together, but surely she would understand if she told her that she knew nothing about it until it was happening, and didn't have a choice in the matter. Fluttershy was her friend. She wouldn't abandon her, right?

The smell was starting to disturb her. Over the time that had elapsed thus far, she'd had bigger problems to worry about, but now that things had calmed down, she was made aware that the smell of the animals and Flurry had been drowning out the feces that had been permeating the air around her. What's worse, because her mouth was forced open, she could almost taste it.

The only way to keep the taste off her tongue was to look down and breathe out through her mouth, which only served to dehydrate her quickly. The salt water in her anus seemed to be drying her out, too. She needed to rehydrate, and she couldn't do that on her own anymore. No hands, no magic, and no ability to call out to Flurry for water. She would just have to wait. She wondered what was taking Flurry so long.

After what felt like two hours, The barn door was unlocked and slid open. "I'm back," called Flurry. "Did you have fun while I was out?"

"Ngoh, hichhechh," answered Twilight.

"Well, then this will be good news," replied Flurry. "While I was out, I met a new friend who wanted to meet you. I couldn't say no to him, and right now, neither can you."

Twilight's eyes shot open, and she shifted in her bonds, vainly attempting to look behind her. She hoped that her shifting in her bonds would send up a red flag for whomever was looking at her exposed, dripping fanny. She then felt a finger running between her labia, testing the moisture level. It was sticky at the top, but the parts that were coated more heavily were still fairly slick. She felt the hands come back, spreading her used cunny as wide as it would go without breaking anything.

"You're about ready for him," confirmed Flurry, smacking Twilight's arse. "I'm just going to cast a quick spell on you." Twilight felt the light tingling of magic on her abdomen, then it stopped. "That should do it. Now, just let me prepare him."

After a few seconds, Twilight could hear a mild slurping sound, followed by a moan from her niece. It was muffled, as if her mouth was full. Was she sucking off a stallion before he would mount her? At the very least, she was grateful for the extra lubrication, but an introduction would have been better. She would have been made more comfortable, given everything that had happened today. Perhaps he would have even been good enough to let her control the pace.

The sucking noise stopped, and the snare that held her down shifted again under the weight. Whoever this was, he was big. The frame began to creak, which made her think he was bigger than the ox. Again, she began to panic when the head of his cock pressed against her vagina. With a good, solid push, he shoved the whole thing inside of her. It was a stallion, alright, but this was no pony. This was a full-sized horse. She could feel his flare all the way up in her chest, well beyond how far her vagina reached.

"I rubberized your insides," explained Flurry. "You're now really stretchy, but without losing any of your tightness. Aren't I just the living end?"

The horse began to thrust, the head of his penis pressing hard on her diaphragm, essentially forcing her to exhale on every thrust. The rig that held her in place made snapping and groaning sounds, to the point where Twilight feared that it would break, and he'd come down on top of her, crushing her under the weight of his chest.

The strange thing was, she was starting to like it. None of the other animals had been particularly pleasing to her, but this monstrous dick was designed to work a pussy like hers. Granted, he was supposed to be in something a lot larger, but the shape was just what she needed. She began to moan out in pleasure, closing her eyes and imagining it was a version of her brother that was much larger.

"Are you enjoying yourself, Auntie?" teased Flurry, hoping to embarrass her. "Are you enjoying being a fucktoy?"

"Yech, hichhechh!" shouted Twilight, her tongue hanging out through her gag. While the idea was unbecoming and the pain wracking her was a challenge of endurance, there was a tiny spark of pleasure building inside of her, and as that was the only good to be found in this moment, she focused on it, letting it wash over her as she pushed everything else out of her mind.

While Flurry was disappointed that her punishment was not so punishing anymore, she couldn't help but smile. After this was over, she would have a new mare to do anything she wanted to. She would practically be able to rule over all of Equestria, being praised for all of the beneficial decisions, and not having to take the heat if things went bad.

As the horse filled her to bursting, stretching out her abdomen like a balloon, Twilight climaxed, squeezing and milking him for all he had. As she lay panting, exhausted and dehydrated, she heard a click just before passing out.

Chapter the Twenty-First: Closer

Twilight awoke atop a pile of hay, stripped completely nude with both dogs pressed up against her. One was draped across her thighs, the other curled up by her shoulder, sleeping with his head between her breasts. Her whole body ached, not the least of which was her head.

With a good deal of effort, she pulled herself up to her feet, waking the dogs in the process. They stretched their legs and watched as she moved over to the wall. She was shaking, unable to find her center of gravity. As she pressed herself against the wood for stability, the ox looked at her out of the stall door. She didn't want a repeat of her time with him any time soon. Not without some careful preparation, at least. Nevertheless, his stall door swung open and he approached, hooking his horn under her arm. With a bit of nudging from the dogs, she managed to pull herself onto his back. He proceeded to carry her out of the barn, her magic unlatching the door.

It was the middle of the morning, the sun shining down on her crusty body. Dried cum was flaking off of her, congealed blobs stuck to several parts of her skin, and a torrent of sticky fluid dribbled out of her vagina. Despite this, Twilight was in a good mood. The sun felt nice on her skin, she was unlikely to be seen in this state, and most importantly, her contract with Flurry had been fulfilled. If she could rehydrate and bathe, she could probably deal with the aches in her body. At worst, she'd probably be a bit sluggish for the next few days.

The ox stopped at the back porch and let her slide down. She thanked him with a kiss on the forehead and pushed herself inside. Flurry was standing in the kitchen, next to the stove, cooking breakfast. She turned to the opening door and smiled. "Oh, good, you're awake." She was wearing an apron to protect herself from the oil spatter, and nothing else. "There's grapefruit juice on the table, and a towel on the chair."

Twilight was grateful for the chair to stabilize herself, and more thankful for the juice. She may have been pumped full of fluids, but she really needed to rehydrate. The glass was gone in less than five seconds, and immediately refilled twice. As she finished her third glass, the world stopped spinning around her and her headache was just beginning to subside.

"What happened?" asked Twilight, a nasty rasp in her voice.

"You passed out," explained Flurry. "Right when I was about to make things more fun for you."

"I thought that was a punishment?"

"In the beginning, but then I decided on my walk to let you off the hook and just have fun. I'm somewhat sad you missed most of it. We'll have to do it again sometime, but without the punishment first."

"What happened to the octopus?"

"Fluttershy came by to take Clyde back home."

Twilight spit out the mouthful of juice she'd taken a sip of. Fluttershy had been here while Twilight was out cold?

"Don't worry," chuckled Flurry. "He won't say anything, and she didn't see anything. She didn't even know you were here. Your secret is safe from her."

Twilight took a moment to calm down. She hadn't expected Fluttershy to show up. She hadn't told anyone she was coming here except her escorts. Nopony should have known.

She calmed down more completely when Flurry served her breakfast. Julienned fried parsnips, eggs and buttered grits. It was a hearty meal that Applejack had cooked for her several times, and Flurry was certainly not bad at it.

After a warm shower with lots of scrubbing, the rest of the weekend was peaceful. They tended to the animals together, took in the fresh air and the smell of corn, and had nice, quiet chats on the porch. They slept together in the bed, and generally had a good time. As promised, the farmer returned on Sunday night, and they parted ways, returning to their home castles. Twilight was glad to be home, as were her servants. A lot of the staff kept smiling at her and leaping to aid her at every call. After a week passed like this, Flurry called Twilight up to the Crystal Palace, with express instructions to bring her evidence to be destroyed.

"So glad you could make it," smiled Flurry, hugging her aunt. Twilight hugged back, genuinely happy to see Flurry for the first time in months. Her troubles were almost over, but for the burning of the evidence against each other. Flurry grabbed Twilight's wrist and pulled her up toward her room. "Come on, I'll show you what I've been working on."

As the lock clicked shut, Twilight's face turned serious. "I have mine," she said, pulling out a file folder with a few dozen sheets with a disposable film reel taped to the side. "Are you ready?"

"I am," answered Flurry, lighting the fireplace. "All of my evidence of you and Daddy having sex, ready for disposal." She held up a large binder, opened it up, and removed the last fifty pages, emptying them out into a big pile. She also had a big stack of film negatives, and a box full of copies. "Whenever you're ready, Aunt Twilight."

Twilight nodded and chucked her pictures into the fireplace, where they caught immediately. Flurry did much the same. When it all turned to ash, Twilight breathed a sigh of relief. Finally, she could be with Flurry on equal ground. They could finally return to normal, with the added bonus that they could sleep together.

"Now that that's dealt with," smirked Flurry, "I actually do have something to show you." She reached under her bed and pulled out a new binder, larger than the one she had just removed pages from. She placed it on the desk and opened the front cover. Twilight's eyes went wide. She was being drilled in all three holes by law students, being fucked by a horse, and gargling the balls of a mutton chopped stallion. As the pages turned, there were more and more pictures of her being fucked by dozens of stallions in the barn, including her castle staff.

"Before you complain, the deal was that I wouldn't take pictures of you and Daddy," chuckled Flurry. "Now, I think you and I should negotiate a new contract. I would hate for this to become public knowledge." As she lay back and spread her legs, an evil smile spread across her face. "Eat me out, and I'll dispose of one."

Chapter the Seventeenth: Release the Hound

Twilight tested the strength of her bonds. It was about noon, meaning they would be here until midnight. Flurry was running her hand over her aunt's shapely arse, squeezing it as she peeled away her panties. "So this is your plan, is it?" asked Twilight, looking to her left, as she couldn't see behind her. "Your last hurrah was to lock me in the stockades and fuck me silly?"

"Originally, no. I was going to make it very intimate, perhaps have mother and father pound you into ecstacy with their dicks while I watched. But then you had the gall to push against me. I had to ask myself, 'What sort of thing can I do to really teach her who is in charge here? What can I do to make sure she never tries a stunt like that again?' Well, you'll soon have your answer. Your last sex with me under this contract will be a punishment for trying to weasel your way out."

A sawhorse was wedged under Twilight's chest and gut, keeping her backside elevated and her genitals exposed to the air. Her skirt came all the way off, and her ankles were secured in place. Lastly, a wide belt was wrapped around her torso, keeping her wings in place. The only substantial movement she still had as an option was her ability to speak.

"So it's to be hardcore BDSM, is it? Fine. Let us proceed."

Flurry burst out laughing. "You misunderstand. This is a punishment, but as I said at the opening of the contract, I'm not trying to cause you harm. A single whipping that's powerful enough to cut your skin, and our contract is null and void in your favour. Why would I risk causing you that level of harm?"

"Then what is my punishment?"

"Humiliation."

"Showing ponies not involved is a violation of the contract, too," reminded Twilight. "And as you said, we're far from anypony."

Flurry stepped in front of Twilight. She had a rather large dick and balls, but the rest of her body was the same. She chuckled as she slapped her cock against the side of Twilight's face. "I don't need anypony else in order to humiliate you, Twilight. I can do that entirely on my own."

"By making me suck you off?" Twilight had a cocky smile. "I've done that several times already." As evidence, she stuck out her tongue and opened her mouth.

"Oh, you'll be sucking me off, alright, but there's more to it than that." As Flurry drove her cock into Twilight's throat, she reached over the stockade. Twilight heard Flurry's magic activate, then a whistle as Flurry patted her arse. "There are some things far more humiliating than being watched, Twilight."

Just as Twilight was wondering what Flurry was hinting at, she felt a hot, moist breeze across her snatch. It was like something was breathing on her. Another few pats from Flurry, and Twilight felt some thin, hairy arms wrapping around her waist. She jerked her head to the side instinctively to find out who this thin, hairy intruder was, but her head was kept in place by both her bonds and Flurry's dick. All she managed to do was wrench her neck. Her eyes went wide as she felt the pointy, triangular tip of a very fat dick pressing at her entrance. She tried to squeeze shut, but her legs being pried apart made that a lot more difficult than it had to be. As it slid inside, she could at least be grateful that, while it was wide, it wasn't very long. As her assailant began pumping quickly in and out of her, Twilight looked up at Flurry with pleading eyes.

"Now, Twilight," smiled Flurry condescendingly. "If I let you out, this wouldn't be much of a punishment. You are to sit there and take his cock. And he deserves to stick it in you." She turned her attention to the thing on Twilight's back. "Because he's a good boy. Yes he is. Yes, he is a good boy."

As the dick pounding into her picked up speed, everything suddenly clicked in Twilight's head. She was held in place, the male that had mounted her was covered in hair, was a "good boy," and this was meant to be more humiliating than being watched by an audience. Twilight had been selected for use as a fuck toy for a dog.

As if he were laughing at her, the dog barked twice, confirming Twilight's misfortune. She'd never felt so low as she did now. Her niece was filling her throat, so she couldn't speak, and her vagina was filled with a presumably dirty dog dick. To top it all off, she couldn't do anything about it, as she was bound not only by the multiple tethers, but also by her contract with Flurry.

Suddenly, she felt the dog pressing hard against her. He hadn't been at it for very long, just a minute or two. She was relieved at the thought that this would at least be over quickly. Then he pulled his hips back and slammed them forward again. This push finished his assault on her pussy, as now his whole length was up inside of her. This would have seemed to not be a problem, as it wasn't long. However, at the base, there was a big, hard, thick knot that effectively locked him inside of her as he sprayed his seed up into her pussy. To make matters even worse, he dismounted and turned around, tugging on the knot inside of her.

Twilight had tears in her eyes as she looked up at Flurry. This was more than she could take. She wanted to apologize for her brazen behaviour and stop this whole thing. But Flurry wasn't looking at her, her attention on the dog and on her next move. There was a great deal of time left, and a great many things she wanted to do with Twilight.

After several minutes, there was an audible pop as the dog pulled himself free of Twilight's grip. Flurry pumped a few more times into Twilight's mouth, and came down her throat. As she pulled out, the dog came around to the front and licked Twilight's face, his tongue slipping inside of her mouth.

"Please, no more," pleaded Twilight. "I'm sorry I fought you on this. Please, can we go back?"

Flurry kneeled down. "I suppose we could, but I already paid the deposit. Besides, I want to make sure that you remember this weekend for a long time to come. We have more than eleven hours of your punishment remaining."
