"Thank you for dinner, Ms. Rarity." Diamond Tiara said a few hours later, as she pulled on her saddlebags. She'd arrived maybe half an hour after the sex had wrapped up. She and Sweetie Belle had then spent several hours going over their homework. They hadn't quite gotten though everything before Rarity had called them down to eat, but what little math was left, she could easily get through back at home.

"It's no problem, dear." Rarity said dismissively. "Are you sure you don't want to stay a little longer; finish up your homework, at least?"

"I can't. My parents both said I had to be home tonight, no more than an hour after moonrise. There's some family business in Manehatten to deal with tomorrow morning, and they want me to come with them, to see how to handle it. So they want me in bed early tonight." Diamond explained.

"Well, if you're sure." Rarity conceded, looking out the kitchen window at the setting sun. It hadn't touched the horizon yet, but was only a few degrees off it. "Sandalwood, would you walk her home? I know it's not really necessary," Rarity added quietly, when the filly looked at her, confused, "But he's been a little under the weather the last couple weeks, so he hasn't really left the boutique, and some fresh air would do him good."

After a second or two of thought, Diamond asked, "Do you want me to take a detour, or something? Maybe make sure he isn't backed up, or anything?" Little manipulations like that felt familiar to Diamond Tiara. And good. And doing it for a good reason, like this, felt better than it ever had when she'd done it only for selfish gain.

"Oh, you needn't worry about that, my dear. He gets plenty of relief around here. Of course, that doesn't mean he couldn't do with a little more, if you feel in need of a little relief of your own." Rarity whispered into a pink ear. "And taking the long way home wouldn't do him any harm, either."

A minute later, Rarity watched the human and the filly walk away, before turning back to the kitchen, where Paisley and Sweetie Belle were cleaning the table. Rarity joined them, putting the leftovers away, before letting the other two go and starting to wash the dishes. Her magical dexterity made quick work of the chore, and she was soon heading upstairs, planning to spend her evening reading.

Her plans were derailed, however, when she passed by the open door of her sister's room, and saw two pale bodies curled up together. They were kissing, slow and deep, Paisley's fingers running through Sweetie Belle's mane, and Sweetie Belle's pink and purple tail flicking side to side, caressing the woman's leg and hip.

Rarity watched for a second or two, and just before she headed back to her room, she saw the two roll so Paisley was flat on her back, Sweetie laying on her torso. The kissing continued a second or two more, before Sweetie started kissing and licking down Paisley's neck. Then down her chest, with quick nuzzles to her breasts.

The sight of her sister kissing down the flat belly, her little body wiggling backwards so she didn't have to get to her hooves while on top of the woman, made Rarity aroused. So she kept watching as Sweetie Belle worked her way off the larger body completely, at which point she turned her head and started laving Paisley's thighs.

At this point, Paisley curled her legs up against her body. Slowly, so that Sweetie could reach the whole length of her legs without having to do more than raise the front of her body. Once her legs were curled all the way, Paisley wrapped her arms around them to hold them in place. She also wiggled a little, to fully expose her pussy and ass to Sweetie's tongue, even though she knew her attention would be focused elsewhere at the moment. The first swipe of the small tongue across her sole made her squirm and giggle slightly, but the next few started her moaning.

Sweetie noticed Paisley's reactions, but she was too focused on the feet in front of her. Besides breasts and breastfeeding, feet were her biggest fetish. She didn't know why, but she thought they were so intriguing. Especially toes, which were sort of like fingers, but so small and useless. Adorably so, in her opinion. Not that she was thinking about that at the moment.

Instead, she was busy running her lips and tongue over the soft skin before her. Kissing and nibbling the soles. Both the lightly calloused heel and balls of the foot, and the softer arch. Working her tongue over and between the cute toes. Feeling them wiggle as she took them between her lips to suck on them. She even enjoyed the smell of skin and the faint hint of soap Paisley had washed them with before joining her in her room.

Sweetie Belle was so focused on what she was doing to Paisley that she didn't notice she'd gotten to all fours and reached one hoof back to rub her clit. Rarity did notice, though. And being the good big sister that she was, she approached the bed.

"Mind if I join in?" she asked, her voice a sensual purr. Sweetie Belle jumped a little, then looked over her shoulder, into her sister's smoldering blue eyes. She just nodded, before turning back to Paisley's feet.

Now that Rarity had permission, she eased up onto the bed and settled on her belly behind Sweetie Belle. But instead of starting right away, she took a moment to savor what was before her. The bright fur framing the dark gray anus and lips. Lips which were swollen and almost dripping with arousal. The musky-sweet scent of a filly ready for sex that was coming in waves as Sweetie Belle was constantly winking, flashing her little clit and pink insides.

But after a few seconds, Rarity felt her own pussy wink, so she leaned in and licked Sweetie Belle's sex. She dragged her tongue from the briefly-exposed nub, all the way up to her dock, tasting both the sweet and musty openings. After repeating the action a few more times, Rarity focused her tongue on Sweetie Belle's dripping pussy. She timed her licks with her sister's winking, so her tongue would always brush over her clit when it peeked out.

Listening to Sweetie Belle's moans, Rarity waited until her sister was right on the edge, before plunging her tongue into the tight pussy, as deeply as she could. This set Sweetie Belle off, and she came hard, squirting her juices all over Rarity's muzzle and squealing loudly, though the feet she was worshipping helped to muffle the noise.

A moment or two later, Sweetie's orgasm had run its course, and Rarity finally eased her tongue out of the now relaxed hole. After taking a moment to savor the mostly-sweet flavor of her sister, Rarity licked as much of her face as she could reach clean of the cum she'd been sprayed with.

"Who's ready for round two?" Paisley asked a minute later, once Sweetie Belle had caught her breath. Both ponies perked their ears up at that. Seeing that, Paisley scooted up the bed, laying back against the pillows. That left her propped up high enough to watch the other two. To see their faces as she teased her clit with one hand. To see their eyes glaze with lust as she dipped her fingers inside herself.

Sweetie Belle recovered first, and hopped forward, sticking her muzzle right up against the pumping fingers. The sudden movement brought Rarity out of her daze, and she couldn't stop the pout from showing on her face as she realized that her sister had beaten her to the prize.

The feeling of Sweetie Belle's small, thick tongue parting her folds didn't stop Paisley from seeing the cute moue, and she held her wet fingers up, offering them to her owner. She watched Rarity lick her lips, before sitting up and changing into her bipedal form. The sight of the gray cock instantly springing to full hardness made Paisley moan. Or maybe it was the lust in Rarity's blue eyes. Not that it mattered which it was.

As Rarity scooted forwards on her knees, her eyes dropped from Paisley's fingers to focus on her sister's plot, and she smiled as she realized that Sweetie Belle was definitely warmed up enough to take her cock. So she grabbed the pale flanks, and pressed her flat tip against the still dripping lips. Some gentle pressure and a little twisting of her hips later, and Rarity popped inside, making her sister yelp into Paisley's pussy. The vibrations made her buck her hips against the filly's mouth and moan, which mingled with Rarity's groan of pleasure, at feeling the hot, wet squeeze of her sister's body.

Rarity took a second to recover before she pushed deeper. She pushed in up to her medial ring with one slow, steady motion before stopping. Then she took Paisley's hand in both of hers, and sensually slid the wet fingers into her mouth. Keeping her blue eyes locked on Paisley's honey-colored ones, Rarity took her time collecting the tangy nectar from the woman's digits. Hearing a needy whimper brought a sultry smile to Rarity's face, and she started bobbing her head, cooing in return.

For over a minute, she played her tongue over her vassal's fingers, not stopping until well after every trace of flavor had disappeared. Finally letting Paisley's hand out of her mouth, Rarity leaned forward far enough to press their lips together in a loving kiss.

A few seconds later, Sweetie Belle let out a little whine and bucked her hips, drawing Rarity's attention back to her. Realizing that the half-buried cock in her pussy was probably making her sister as horny as the scent still in Rarity's nose was making her, Rarity broke the kiss. Sitting back on her fetlocks, she gripped Sweetie Belle's flanks tightly and pulled back, before pushing forward hard. A pleasured yelp erupted from her little sister's lips, and hearing it, Rarity thrust again, pushing her medial ring into Sweetie's clenching pussy.

Several thrusts later, Rarity's hips slapped against Sweetie Belle's, and she stopped briefly, to let the filly adjust. Once she had, Rarity resumed her quick pace, fucking Sweetie Belle roughly. Even though her sister's grip was almost tight enough to hurt, she was nonetheless wet enough for Rarity to move easily. With every thrust, Rarity would pull back far enough for her medial ring to pop out of Sweetie's pussy, before slamming herself hilt-deep.

To her credit, Sweetie Belle kept up easily, meeting Rarity's thrusts with her own. She also kept eating the pussy in front of her. Nothing too complicated, just basic swipes of her tongue, but it was enough to bring Paisley to the edge in only a couple minutes. And when she heard Rarity say she was getting close, Sweetie started flicking her lip over Paisley's clit, which gave her that last little push needed.

Throwing her head back, Paisley let out a throaty scream as she came. The pleasure washed through her, making her hips buck viciously, and her pussy clenched around nothing as she squirted. It wasn't nearly as much as a mare would let out when she came, but more than a few drops splashed over Sweetie Belle's tongue and lips. The filly kept licking though, wanting to make her partner's orgasm as good as it could be. And it felt great, right up until it didn't.

When the feeling got to be too intense, Paisley weakly pushed Sweetie Belle's face away from her. Sweetie barely noticed, she was so wrapped up in Rarity's fucking. The thorough stretching and incredible fullness. The sound of Rarity grunting with effort. The scents of sex and Rarity's arousal, mingling with Paisley's. The rubbing of Rarity's flare and ring over every inch of Sweetie Belle's pussy, including her g-spot, and the grip of Rarity's hands on her flanks.

All of that had already pushed Sweetie Belle over the edge three or four times. But despite that, the filly was still very aroused, however. There hadn't been enough build-up to any of them to really satisfy her, and she didn't think her approaching orgasm was going to be any different. Not that she could think much at all, in her current condition.

*CRACK*

Suddenly, all thought was obliterated. Shattered by the feel of Rarity's hand impacting her flank hard enough to sting, and the fragments washed away by the warm wetness that engulfed her little horn. Sweetie Belle's orgasm hit her like a freight train, almost rendering her unconscious. Her body clenched front and back, leaving her mouth open wide in a silent scream as her throat locked, and nearly crushing her sister's cock. At the same time, she also squirted front and back.

Rarity was almost as overwhelmed as her little sister. The grip on her cock had grown to a slightly painful crushing, but the splashing of pussy-juice against her hips and the feel of raw magical energy flowing through her mouth set Rarity off. As Sweetie's pussy relaxed in between squeezes, Rarity's cock swelled, her cum rushing up the shaft.

The first shot overfilled what miniscule free space there was within the younger sister, and most of it sprayed out, splattering against the elder's hips. And it was immediately followed by more filly-cum as Sweetie Belle's pussy clenched again.

As Rarity ground her hips against Sweetie Belle's, her second shot went the same way. A little made it into the tiny womb, but not much. Sweetie Belle was too young for her cervix to spread and accept the widely-flared head, and the cum was moving fast enough that it mostly just splashed off the back of the tight pussy.

Even so, Rarity kept grinding her flat tip against her sister's innermost barrier as she unloaded. She also kept up the suction and swirling tongue on the fluted horn in her mouth, almost mindlessly. She wanted her sister to enjoy this as much as she was, and she was doing everything she could to ensure she did.

A minute or so later, the two finally wound down, and Rarity managed to shuffle back far enough for her softening cock to lewdly squelch out of her sister's pussy, before collapsing to one side. While the little hole was gaping wide enough that Rarity could probably see everything, if she were inclined to look, almost no fluids started draining.

Mostly because nearly all the cum had already been forced out, a lot of it decorating Rarity's groin and her thighs. A lot more was pooled on the bedspread, which was an utter mess. It was going to take a lot of scrubbing to get the blankets clean.

"Or a simple trick most of us pick up in a couple weeks." Paisley thought to herself as she got to her feet. She picked up the exhausted filly, holding her under one arm as she folded the bedspread back with the other. When she was put back on the bed, Sweetie curled her legs up, and drifted right off with barely a sound.

Rarity, however, was a different prospect entirely. Especially since her bipedal form was nearly the same size as Paisley, herself. Fortunately, a judicious application of magic made it possible to move her without disturbing her too much.

Now with both ponies off the covers, Paisley had no problem pulling them off the bed and laying them on the floor, cum-stained side down. A few seconds later, she folded them up loosely, with most of the cum now gone, thanks to the cleaning spells built into the floor. She tossed them in the hamper on her way to get a clean replacement.

Once Sweetie Belle was tucked in, Paisley turned her attention to Rarity. She helped the groggy, but semi-lucid unicorn to her hooves, and started for the master bedroom. With a stopover in the bathroom, so Rarity could clean up enough that she wouldn't ruin the bed when she got in. She also had to rinse out her nose, because some of Sweetie Belle's juices from her first orgasm had sprayed directly up her nostrils, and if she didn't clean them out, the scent would drive her mad all night.

"Paisley, would you mind terribly waiting up for Sandalwood to return, then you two lock up?" Rarity asked, as she walked to bed—tired, but under her own power, at least. And on four hooves, as she preferred.

"Of course, Miss."

"And don't forget, breakfast at seven. One poached egg, tea, and toast. Lightly browned and unbuttered." Rarity reminded her, as she settled herself under the covers. Despite waking up a little bit while getting ready for bed, Rarity was out in seconds.

Paisley then dimmed the lights, and headed downstairs to find her fellow vassal was just returning. It only took the two few minutes to get everything set for the night. Getting themselves ready took several minutes more, but they had soon joined Rarity in bed, and drifted off to sleep.

Author's Note

I had thought up the background of this story months ago—inspired by the description of Your Human and You, which I actually stopped halfway through writing this to read, since my curiosity finally got the better of me.—and laid out most of the rules of the verse in my head, though I didn't really have any particular scenes in mind. Then the contest came along, and I realized that this could actually cover at least five of the fetish categories, and I couldn't resist the urge to write it. And I'm glad I did, as it helped me flesh out the details a bit. Such as the whole 'enchanted floors to deal with the bodily fluids everywhere' thing. It also got me to go with the word vassal, instead of slave. Which I personally feel has too many negative connotations for the fun romp I wanted this to be.

This story was written not to see if I could—the other one proved that—but because I could. So again, anything I win is strictly for bragging rights and the money is unnecessary and unwanted.
