Cumming Between A Married Couple

Cadance and Shining's dining room was huge, palatial. But here, at the table with just the three of them, it felt almost claustrophobic. It might have been the intensity of the two across from her... it certainly was. Rarity felt like she was being sized up. She almost certainly was.

Twilight had taken Flurry Heart out for the night, and told her marefriend to 'have fun'. 'Happy Birthday', she added, as well as 'Remember how wonderful I am, okay?'.

Rarity refilled her glass of white wine. It was a particularly sweet riesling, good for desserts, and something she suspected Cadance would have had a strong preference for. Unfortunately sweet wines aren't overly strong, and there wasn't much more than a buzz tingling through her hooves at the moment.

As much as she was excited for the company before her, a little bit of liquid courage wouldn't have gone amiss. Cadance seemed to notice the look in her eye, and smiled reassuringly, touching one of Rarity's hooves with her own.

"You can say no anytime. That's the thing about fantasies. They're exciting to think of, but then actually doing it?" Cadance sipped her wine, grinning around the rim of it and -- Rarity couldn't help but blush as she flicked her tongue around the rim, being sure to make a wholly uncomfortable amount of eye contact -- "But we're excited to have you."

Shining chuckled, rubbing a hoof against Cadance's thighs under the table. She leaned back into him and purred happily. They were so wonderful together, Rarity decided, that she really must have them both. Another mouthful of wine, being sure to make it look like she wasn't rushing.

Judging by Shining's renewed chuckle, the game was given away. She blushed further, head bowing slightly as she felt herself tuck further into her chest. Why did she try to lower her profile defensively when she was only at social risk? Stupid pony brain.

"I will admit," he admitted, swirling his own bottle of beer -- a stronger one from the North, Rarity noticed. She watched him carefully. He looked back with an even, steady expression... he was nervous too, was he? Then he smiled with just one corner of his mouth, and no matter his nerves, he was definitely handling it better than Rarity was, as befit an officer of his station, "This seemed so much simpler in my head. You have to remember, Cadance is the only pony I've really been with, and we've been together since highschool."

Cadance squeezed him tighter. "You're being such a big brave soldier for me, aren't you?"

Shining sipped from his beer, wiped his lips with the back of his hoof. It was such a simple gesture, but the way he did it was just so... unexpectedly masculine? Like a true workhorse. Rarity felt herself twitch slightly.

Across the table, Cadance gave her a look that just screamed 'I know right??'

"I'm not really sure what I'm doing here," Shining admitted, "but what stallion hasn't always dreamed of a threesome with two mares so beautiful? Besides. Cadance can be a bit insatiable, even for my stamina."

Cadance sighed dreamily. "Oh, and what stamina..." Shining squeezed her tighter and kissed her forehead. Rarity's legs squirmed under the table. It wasn't just the idea of sharing them physically... the shared intimacy between them was making her feel very... warm.

Rarity nodded, relaxing everything but her knees. Those remained locked tightly together for the moment. "Monogamy is interesting, isn't it? It's not like you'll love Cadance any less, or she you, but sharing can be... difficult."

Shining hid a smile behind a hoof, badly. "Element of generosity?"

"I know how difficult it can be. But I also know how rewarding it can be." Rarity could be brave too, certainly. She studied Shining closely as she made her own eyes at him across the table, and she rewarded him with her hungriest smile.

His expression remained neutral, but he betrayed himself with an extra long slug of beer. Cadance wiggled her eyebrows at Rarity as she nibbled on her husband's ear. It was good to see someone was confident about the situation.

Cadance whispered something in her husband's ear, then. Rarity couldn't hear it, but whatever it was, Shining's eyebrows shot right up, and he stared into Rarity's eyes intently. Watched her closely, as Cadance very intentionally dropped a fork.

"Oops"

As she ducked under the table to get it, Shining reached across the table and grabbed Rarity's hoof in both of hers, still watching her intently. Then Rarity felt her knees part. She looked down to see gleaming, mischievous eyes and... a very pink Princess head. Cadance started kissing between her knees, working her way up Rarity's thighs--

Shining cleared his throat loudly.

Rarity looked back at him, his expression still... intense. He was so still. He knew exactly what was happening, didn't he? "I'm sorry, Rarity, you seem distracted all of a sudden?"

Oh, the coy bastard.

"I'm sorry, darling, I don't know what came over me."

He kept a hold of her wrist as Cadance kept working slowly up her legs. She was right by her hips now, nibbling on the joints. Rarity felt hot breath as Cadance switched between sides, but Shining's gaze kept her absolutely still as well.

"I'm not boring you, am I?" His smile was reassuring, but his eyes were cold, calculating, darting across the features of her face every few seconds, assessing her, "Cadance is the more social of the two of us. I’m still Twilight's brother at the end of the day. How is she?"

Rarity struggled to think as Cadance moved in for the kill. Her tongue started low, taking an agonizingly slow lick right to the tip, burying under Rarity's folds and around her clit. The whole time Shining was staring her down, daring her to react. Rarity didn't move, didn't let out a whimper.

She could taste her heartbeat in her throat.

"She's wonderful, as always." Rarity gasped out. How long had she been holding her breath for? She hadn't noticed. "Was very excited to spend some time with her niece."

Shining's smile was the perfect image of obliviousness, which is how Rarity knew he knew exactly what he was doing. He hadn't let go of her hoof. She realized now he had been taking her pulse. He squeezed her wrist again and she looked into his eyes.

He broke from his act for just a moment, just a moment. The grim soldier was gone and in its place the goofy, dorky brother that Twilight recognized so well winked at her, flicked a warm smile like a lightbulb that burns out the moment it holds a current. Grim soldier again.

What-?

"I don't know what my sister sees in a slut like you," Shining said, watching her mouth. Rarity's beating heart stopped just a moment, then Cadance's tongue swirled around her clit again and it remembered why it was pounding so fiercely, "You have a beautiful mare between your legs and you don't even make a sound."

Rarity tried to shift to look back down, but Shining kept squeezing her hoof. Cadance just giggled.

"My wife starts eating you out in front of me, and you think you can hide it from me? You're keeping an impressively straight face, slut."

"Ah-" Rarity gasped. Cadance was groaning into her now. Was she touching herself under the table? Another moan. She had to be. "I'm sorry?"

"Were you intentionally trying to hide it from me?" Shining leaned forward, got that much closer to Rarity, until the tips of their horns were almost touching. She felt interrogated. In front of her was a true soldier, and he played every part of it well. "Did you think you could hide from me, you stupid little bitch?"

"Ah! No, no sir." Rarity squirmed in her seat. Cadance had wrapped her legs around Rarity's thighs and was holding tight. Neither of them were going anywhere.

"Then why were you so quiet? You have the most talented tongue in Equestria in that loose cunt of yours, and you've hardly made a squeak. Are you that unappreciative?"

"No, she's... she's very talented. I'm sorry. I just hadn't wanted to... upset you."

"I trust my wife completely. If she wants to amuse herself with a new toy, that's her business. But I expect you to be more grateful for the attention."

He let go of her. Rarity could finally slide down her dining chair a little, see under the table again. Cadance's mouth was tight around her at the moment, and those eyes looked right back up at her. Rarity squeaked, couldn't help it, and blushed in embarrassment at her own noise.

"Better," Shining seemed to approve, "but I haven't heard a thank you, yet."

"T-thank you, Mrs. Cadance."

Cadance hummed happily, which sent wonderful vibrations through Rarity's pelvis all the way up her spine, tingling against her scalp and the back of her neck. Cadance seemed to notice and giggled, meaning the effect came back in little fits and sparks and bursts...

"Mmmph."

"Is that good enough for you, love?" Shining asked under the table.

Cadance came away from Rarity, and she could have cried. She'd been so close. These two were co-ordinating far too well. "I think she could be more grateful. But in fairness, I'm sure you're being too ungenerous to her."

"Oh? You think?"

"You would not believe how wet she was before I even started," Cadance giggled. There was the wet sound of an especially sloppy kiss, and Shining made a groan that sent all new tingles rolling up Rarity's back again. It was rare to hear a stallion so... pleasantly vocal. And Cadance made more of those wet little noises in response. "If anything, I think she's a needy little whore. She was probably just too scared of admitting how desperate she was to you, my wonderful husband."

Rarity froze. Shining nodded. "Is this true? Were you just scared of admitting what a horny, degenerate slut you were that you'd come between a married couple just to get a few silly orgasms?"

"I- I'd never want to come between you!"

Cadance giggled under the table, and Shining let out a low, throaty growl as she did. "Don't be ridiculous, my beautiful new toy," her head popped up above the table for a moment, "of course you want to cum between us. That's all you're here for, isn't it?"

"Yes." Rarity admitted.

Shining backed out from the large dinner table, and his gaze froze her again. Like it implied she needed permission to even breathe. She felt too afraid to ask. Her heart was starting to ache, but gods was she burning hot for it.

"Did you even notice you started touching yourself?" Shining said as he circled around the table, those steely eyes holding her in place.

Had she? Oh, she... she had. Look at that. She couldn't stop herself though.

"It hurt. Without Cadance there. I was close." It took three heavy gasps to get through.

There was a tap under the table on her shins. It took all of her willpower to look away from Shining, stalking up to her, but she saw the grinning Cadance with her soaked muzzle perched between her legs under the table.

"Oh, you want me to continue, do you, my own little toy Rarity?"

"Yes, please." Rarity whined, properly whined, shrill and miserable and desperate and needy.

Cadance tapped her again, pointing towards her husband. "Tough. Because I'm afraid it’s his turn with you now. And I think you have some making up to do."

Shining had closed the distance far faster than she noticed. How could he move so silently on castle floors? Rarity was hoisted up onto the table, her hips over the edge, Cadance holding her legs apart.

He leaned forward, his hard cock still slick from Cadance lined against her back, letting her feel exactly how deep it was going to go and... well, Rarity was used to Twilight, wasn't she? Her brother... that was very... new. When was the last time she'd been with a stallion even?

Never one this big, certainly. Cadance was a very lucky mare, and here Rarity had the audacity to think she could share... she really was a silly little slut, wasn't she?

Shining nipped at the back of her neck, and ran a hoof through her perfectly styled mane, utterly ruining it. Fine. Let her be ruined. She wanted it so badly.

"Now, I know you're nothing but a cock-hungry whore desperate to be filled any way I care to give," Shining said so matter-of-factly, so businesslike from just behind her head, "but are you sure you deserve this?"

"Oh, Hades, just rut me, please."

"Because you're a stupid, horny little bitch that thought she could share in an honest, decent pony's marriage?"

"I'm sorry!"

Shining bit the back of your neck. "I think we forgive her. Sweetie?"

"Oh, yes. As long as she lets me play with her a bit more."

"She'll certainly have to earn it." Shining said, pulling back and lining himself up with Rarity. “You’re about to get fucked by a Captain of the Royal Guard. A real stallion. And what are you?”

Rarity pressed her head into the hard wood of the dining table, gritting the linen tablecloth between her teeth when she could. “A needy slut, desperate for cock!”

Cadance thumped the table twice. “You heard her, love.”

Shining leaned forward, biting the back of Rarity’s neck, and took her.

It was so much more than Cadance’s tongue.

It was so much more than anything Twilight had ever used on her.

“I’m going to have to clean this whore off my cock when I’m done with her, honey,” Shining grunted. Rarity felt her muscles melting.

Cadance apparently took that as an invitation to get started. Rarity felt that now-familiar tongue force itself inside her. Force was the operative word; Shining didn’t move his cock out of the way for it to fit. Instead Cadance’s tongue pressed it further up, tighter against her clit.

Shining groaned appreciatively. Rarity couldn’t see how, exactly, Cadance had worked her mouth into that position, but it was... splendid. He leaned forward and nipped at Rarity’s ear again. “You know why she does that, slut?”

“F-for you?”

“Mmm. It makes that loose whore cunt of yours just that much tighter for me.”

Rarity shuddered, yelped, whined, and bit down hard on the linen tablecloth. “Oh, fuck.”

Shining chuckled even as he fucked her, harder now. “No, don’t cum yet. And watch that mouth of yours, slut.”

Cadance slapped Rarity on the rump, hard, Rarity clenching down on Shining as she flinched. “And watch that language. I thought you were at least trying to look like a lady.”

Her husband laughed between mouthfuls of mane, tugging Rarity’s head back up off the table, her grip pulling the tablecloth up with her and tearing the linen. She’d have to sew that later for them. “I don’t think there’s much point in her trying anymore. We’ve seen what she really is now, haven’t we?”

“Rarity, do you agree?” Cadance said, moving her mouth back away from the both of them. Rarity shuddered when she heard Shining groan with the same disappointment she felt. It was just those small moments to remember he really was enjoying it too. “Are you a lady, or a depraved slut with no place in high society?”

“Slut,” was all Rarity could get out, from whatever small part of her mind she still had access to. The rest was swirling black, stars and void, as the intensity of the moment eradicated everything else, pushed it into blissful oblivion.

Cadance seemed satisfied by that, because her tongue went right back as deep as she could fit it. Shining had to fuck Rarity shallower to slide past Cadance’s open mouth but, honestly, he really was just the teensiest too big for her anyway.

“Is that why you want to be around the nobility so badly?” Shining asked, sliding entirely out of Rarity, leaving her gasping at the desperate emptiness. She thrashed backwards, trying to force her hips back onto him, desperate for that fullness again, but every time she found she could only graze the tip, couldn’t get him back. He was toying with her. “You’re so desperate to be seen as a lady of class, when all you are is this quivering toy begging, begging to be fucked?”

“Oh, she puts up a good face, usually” Cadance agreed cheerfully, climbing out from underneath the table, nuzzling Rarity’s flank, “she must be so desperate.”

“Desperate!” Rarity agreed with a squeak, pushing back off the table until Shining held her down with his magic. He was so gentle about it, actually. He just held her until she got tired, then slid her back away from him when she rested for her next desperate attempt to get his luxurious cock back inside her.

Rarity heard Cadance at Shining’s side, suckling on him. Just the occasional sound of suction leaving wet flesh, of a jaw lolling to make a better fit. “It’s such a pretty face too,” Cadance said as she took a quick breath, “But it’s so much prettier with the messy mane and the running mascara.”

“It suits her. Better shows what she really is. A desperate little slut, all for us to play with,” Shining agreed, running a hoof between Rarity’s thighs and almost but not quite, just not quite touching her. “We might need to be better role models.”

“We could,” Cadance agreed thoughtfully, “or you could let me break her a little?”

“I’m sure Twilight wants her back mostly in one piece.”

“Mostly,” Cadance agreed. “You’ve been far too forgiving with her.”

With legs that wouldn’t stop shaking, and balance she absolutely lacked, Rarity managed to squirm onto her back so she could watch the couple at the moment. It was worth whatever it took, really. Shining was leaning over her, amused. He didn’t help, but he didn’t stop her either. Just gestured with his eyes down at the sight of Cadance...

Cadance, throat-deep on him. Those small noises that betrayed her were astoundingly small for how much she was taking, which seemed to be all of it. There was an indulgent dignity to it, just in the absolute control of her speed, her unwavering steadiness. How much must she have practiced to do this?

Shining nodded. “She’s doing a good job cleaning the whore off me. This is how a lady sucks cock. Are you learning anything?”

Actually, Rarity was. Her only regret was that she was still so absolutely out of her own mind at the moment that she couldn’t appreciate the masterclass she was observing. She reached down to touch herself, but Shining’s magic caught her hoof just as it went as low as her stomach, and held it. Delicate, not even tight enough around to cut off circulation.

Cadance’s eyes were open, Rarity saw now. Not closed, not blissed out like she felt. Studying Shining’s face, looking up at him with the most radiant love, assessing his reaction of every movement, every flick of her tongue where she could.

There was another pop as Shining hauled his wife up and pulled her into a deep, deep kiss. He dipped her, holding her lower and lower, holding more of Cadance’s weight until they had a pose like salsa dancers. Rarity was about to marvel at the trust between them, but realized... well, here she was, fucked silly on their dining table, and not once had either of them shown even a flicker of jealousy.

She was starting to understand the appeal of Twilight’s idea that the body may do what it may, but the heart will stay.

Then Shining put Cadance back on her own hooves and pulled Rarity up off the table with a foreleg wrapped around her back, just under her shoulders, and his eyes flicked up and down along the features of her face.

“You know, this really is a good look for you.” He agreed.

Rarity’s heart pounded. She’d said she’d enjoy being appreciated as a work of art but... well, there really was the sculpted aspect to it now, wasn’t there? They were shaping her to their own preferences...

Shining kissed Rarity. He moved in slow, delicately. Rarity had always imagined wanting the fastness, to be taken, and there was an appeal in that. But his slow approach made her anticipate it, let her realize what was happening before experiencing it and hold the idea of it in her head...

And it gave her plenty of time to pull away if she chose to. There was an implicit request for permission from it, even though Shining had all the power over her in this situation.

Rarity leaned into it.

He rolled her bottom lip between his teeth, held the bottom edge firm and dragged the bite down to almost the gum line.

They broke away, Rarity gasping, Shining just smiling in a way that might be mistaken for ‘smug’, but just seemed fetchingly confident. Confidence really was attractive in a stallion... from the way his wife was looking at him, as well, that seemed a shared opinion.

“I’ve had my turn,” Shining declared, “I feel like Cadance wants hers now.”

“Hasn’t she... hasn’t this already been it?” Was that excitement or terror in Rarity’s chest? She couldn’t tell. She felt it far too strongly.

“Oh, no,” Shining grinned, pressing his forehead tightly to Rarity’s, until his smiling face was all she could see. He was still holding her weight, which felt... nice. “This was mine. I wasn’t sure how I was going to feel about sharing her, so she said I should start and see how I feel.”

“And... if I may ask, how do you feel, Sir Armor?”

Shining kissed her again, closed mouthed and almost chaste. Almost. “I feel like there is nothing in the world I’d like more than to watch my wife absolutely ruin you. Your white fur was just meant to hide the stains, wasn’t it? Let’s see just how many it takes before it shows through...”

Rarity shuddered, and whined as she couldn’t shift her hips back into him. Apparently he’d had his turn.

Shining helped her off the table, and let her regain some of her dignity. She stood as proud as she could, given the tremors running through her legs. Shining started leading her to the door.

Cadance walked ahead of them, and Rarity saw the expression on her face for just a moment, as she looked back over her shoulder.

It was the same one Twilight had when she was doing calculus in her head. Focused, calculating, completely unaware of anything else.

And Shining? Shining was being so gentle, leading her ahead.

Rarity realized she was truly doomed for this world.

Still she let Shining lead her to the bedroom, even as her legs trembled all the more.

The double doors were opened. The room was... comfortable, and decadent. An ensuite, a four poster bed with velvet curtains, what must have been a swan down mattress a foot thick, floor space covered in wardrobes and dressers and, of course, the balcony over the Crystal Kingdom.

Her eyes lingered over that one, and Cadance must have noticed because she asked, “How’d you like to be bent over that railing and fucked so the whole kingdom knows what a degenerate slut my dear Twilight settled for?”

“I- I beg your pardon?”

The bedroom doors slammed shut behind her. Cadance picked Rarity up and hurled her, properly hurled her, onto the bed. She landed on her back, bounced. Squeaked like a chew toy. Felt like a chew toy actually.

“I’m sure you heard me. Either that or my husband has already rutted your brains out, which wouldn’t be nearly as fun.”

“Of course not, my love,” Shining confirmed, “I’ve left you plenty.”

“Good, good.” Good, good.

Rarity was... confused. Things had gotten far more intense than she anticipated. And here was Shining Armor, walking up to the bed next to her, crawling up next to her, nuzzling her cheek. And there was Cadance, who had previously been so giggly and playful, rummaging around in one of the wardrobes and... she was behind the open door, Rarity couldn’t see.

Rarity looked at Shining in confusion, and he smiled, cupping her chin with his hoof again.

“Surprised?”

“I... I suppose I am, yes.”

“Cadance has been a little... bottled up with me,” Shining admitted. “She loves this sort of thing, but I’m apparently a terrible submissive.”

“He’s far too stoic for it,” Cadance groused from the wardrobe, “if he tries to humour me, I can just tell he’s thinking of all the ways to take control back. And then, worst of all, he does.”

“You love it.”

“I love you!” Cadance agreed, as coathangers rattled and there were some distressingly... zippery noises, “You definitely can’t be faulted for passion or stamina, either.”

“Thank you, wife.”

“So you, my degenerate slut, my ungrateful whore, are going to find out what happens when you don’t appreciate my wonderful Twily enough.” Cadance stepped away from the wardrobe in-

Rarity gulped, and felt her heart rise back up into her throat. Couldn’t blink, eyes just darted back and forth across the details.

Cadance in black knee high stockings. Cadance in a tight black corset. Cadance levitating a thick paddle and making swatting motions with it. Cadance with her hair worn up neat and tight and professional, where it was out of the way. Cadance with her tail tied up, tied back, and not a pair of panties for discretion.

Cadance with that focused look in her eyes.

Rarity trembled where Shining held her. Not down, not from running away, held in reassurance. That he was still here.

“I feel your roles have reversed somewhat.” Rarity tried her best to keep her voice conversational, but it cracked on ‘reversed’. She was somewhat out of her element, mayhaps.

"Oh, Shining is far better at the intense looks and dirty talk. He was a drill sergeant, a lifetime ago."

Shining chuckled, and whispered in Rarity’s ear; "Cadance enjoyed that far too much."

"Watching ponies be so scared of you, knowing you came home looking forward to playing a level 13 Paladin who specialized in Diplomacy and Use Rope? I couldn’t stop giggling.”

Rarity was still on her back, and Cadance grabbed her hind hooves with her magic and hoisted them high so her ass was raised up off the bed, suspended in the air. Rested the paddle up against it, just beneath her tail, but didn’t move it. Just let Rarity test the weight of it.

Shining was still talking in her ear, like he didn’t even notice. "I liked peaceful solutions. I definitely didn't like hurting anyone, even in my fantasies. When you can hold off an army all by yourself, it means you're a little intimidated by your own strength."

"He doesn't even spank me properly, and I was born with flanks begging to be pink. Pinker."

"I think she loves that I'm gentle."

"I do.” Cadance said, “But I'm not."

"No," Shining agreed, "She's really not."

“He did really get good with the rope though.”

Shining pulled out a length of cotton rope from under the bed and flexed it, studying it for kinks and flaws that might be abrasive against the skin, finding none and deeming it good. “You would know better than I would, love.”

“Oh, yes, I would. Would you like to see, Rarity, just how good with rope my darling husband can be?”

Rarity nodded.

“Good,” Cadance nodded, “Because if I’m getting a little eager slut for a present, I want my new toy presented to me in a nice, neat bow. Shining, if you’d be so kind?”

Shining was very kind indeed, and very gentle for a stallion that had nearly fucked her clean through a dining table.

The rope tied her wrists to the headboard, which she just now noticed that the loops and curls of the metal were... subtly perfect for this. Her legs were kept together, and the rope looped three times around her ankles before going up around the top frame of the bed and around the corners. Another loop in the center to keep her legs as they were, but as soon as that last knot was uncoiled Rarity would fall somewhat, and her legs be forced to spread... Clever.

Everything was tight, like tailored clothes, and didn’t resist until she did. But when she tested her binds, they were unyielding. Shining kissed Rarity on the forehead. “Thank you for this. She’s always wanted somepony she can be rough with.”

“Shining? Are you consoling my property?”

“Yes, dear. I want to make sure she’s all in one piece again before I let you break her.”

“Oh, you’re really going to let me ruin this one, are you?”

Shining smiled, kissing Rarity again on the cheek. It was such a loving gesture, more intimate than the ropes and the fucking. “I’ll make sure there’s enough pieces of you to put back together again at the end too, okay? You’ve been absolutely wonderful so far. Thank you.”

“You’re... welcome, Sir.”

Then the first strike of the paddle hit Rarity, and she cried out.

“Well, she can take some abuse,” Cadance cooed, “That’s good.”

Rarity grit her teeth and nodded.

“There are some who would see you as a delicate lady. I’m sure you’d like to think that, wouldn’t you? But you’re much harder than that, aren’t you?”

Rarity nodded.

The paddle hit her right on the upper thighs, just below where her weight would be sitting, sending pain shooting down behind her knees and electric twinges up her tailbone. The blood rushing to form bruises made everything feel... warm, and tingly, and sore.

Rarity moaned as much as she groaned, one bleeding into the other and back again.

Then Cadance struck again, same spot, and Rarity threw her head back and grit her teeth and squirmed, thrashing against the restraints. Shining had tied them well, they didn’t cut or dig into her skin in any way, and took all the abuse she threw at them.

Just as Rarity took Cadance’s.

Cadance hit again, higher now, on the meatier bits around Rarity’s cunt. It was hard enough that as she took it she got pushed back into the mattress from the force of the blow. The surface of the paddle just kissed her lips through the padding provided by her flanks. Just stung them.

Rarity was thrashing her head side to side now, babbling, kicking her weight into the leg restraints and trying to throw her weight back up the bed, away from Cadance. Shining ran a hoof through her mane.

“Cady? Does the slut really deserve this?”

“Oh, she’s fine. She hasn’t even yelled stop yet, let alone meant it.”

“I trust you.”

Cadance walked around, letting her magic stroke the paddle against Rarity’s fresh bruises and the sharpness of the red welts, not even tapping them but again just letting the weight be felt. She looked at Rarity’s wild eyes and Rarity felt her head still, felt compelled to look back into those... eyes.

“Hello, whore.” Cadance was cheerful, bright, chipper. A schoolteacher addressing class.

“Hello, Mistress,” Rarity replied.

“At least she’s a fast learner. You’re getting off on this, aren’t you?”

Rarity didn’t answer, hesitated. So Cadance struck her again, same spot again, a crack that left Rarity’s ears ringing, that made her bounce against the mattress from the force of it, that made her scream and shiver and roll against the restraints.

“I asked you a question, slut, and I expect an answer.”

“Yes!” Rarity gasped, “Yes, please, yes! A little higher, please, Mistress?”

Her Mistress obliged, just under the tailbone and aimed down into her hips. Rarity screamed, and the scream melted into maniacal, desperate laughing.

“yes, please, there, right there, yes, please Mistress, thank you, thank you, thank you-”

Cadance struck her again, same spot, and Rarity howled.

Shining kissed Rarity on the forehead. “My sister always did get the best toys...”

Cadance shushed him. “Twilight can have what’s left of her back later. For now she’s mine.”

“NoooooOoo...” Rarity whined, “Still Twilight’s.”

Cadance crawled on top of Rarity’s chest, legs straddling her. Pinned Rarity’s top half to the bed, which just made the ropes pulling her up feel that much tighter. Cadance was wetting the fur of Rarity’s chest, she could feel it.

“Excuse me, my little whore, all tied up in a bow for me? What did you just say?”

“‘m Twilits.” Rarity murmured, drunk on everything but the wine, “hers.”

“‘Twilit’? Just who is Twilit?”

“My Princess. Miiiine.” Rarity giggled, the throbbing in her ass matching the ringing in her ears, the bulging in her throat just under her jaw, the hammering of her heart.

Shining kissed her again on the cheek, and she felt such love from that. And maybe relief? Gratefulness. She got that, even through the hormonal haze.

Cadance smiled at that, too. “Am I not Princess enough for you?”

“You,” Rarity breathed, “are Mistress.”

“Mmm.” The paddle wound back for another strike, and just as Rarity winced and braced herself for it as much as she could... it gently tapped her, just a flick. “Good answer.”

Cadance shifted forward so her hips were just over Rarity’s muzzle. Rarity could feel the heat, breathe the scene, and looked up at the imposing figure towering over her. Could crush her at any second. Wanted to be crushed.

“Shining, my beloved, tell me. Do you think she can see anything behind me?”

“No, dearest.” Shining said from beside Rarity, checking her circulation with his magic constantly, adjusting the ropes as needed.

“Good, good. Undo that last knot for me, would you?”

The knot that held the two bindings of her legs together as one unravelled, and Rarity’s legs spread towards the new anchor points... the corners of the bed, apart. She was exposed again. You’d think she’d have gotten used to it by now, but with Cadance here, and not being able to see what was going on...

Cadance squeezed Rarity’s head with her thighs, pulling her mouth up to her Mistress’s pleasure, and ground her hips. Rarity’s tongue desperately flicked out to find the spots that felt most rewarding, showed her gratitude for her Mistress welcoming her into her bed.

Shining whispered to Cadance, “Really? That one?”

“You really are far too gentle, sometimes.”

“Well. I suppose if she’s as much a whore as she looks, lapping at your cunt like that, then it might be what it takes to make such a loose slut feel anything.”

“Oh, I most definitely agree...” Cadance purred, pressing down with her hips again until Rarity wasn’t bending her neck to meet her, was being pressed down further and further into the mattress.

Then Rarity gasped as something teased her, something quite big and flared.

“A toy for my toy.”

Shining had been just a little too big for her.

This was significantly larger than he was.

It barely fit. No, it didn’t quite fit at first, but Mistress teased it in. Wiggled it in a clockwise direction, let it move in even slower than it otherwise would, never letting anything get too intense, but not letting anything settle either.

Rarity pushed her mouth down and away from her Mistress, tucked her chin into her chest to exhale sharply, take short ragged desperate painful breaths, let Mistress rest against her forehead for a moment.

Mistress growled down at her. “Unless you plan to let me fuck your horn, slut? Your mouth.”

Rarity took a deep breath, her legs screaming in... well it was pain, but it wasn’t just pain, which was important. She was definitely getting adjusted to it, half-inch by half-inch. She pressed her mouth back onto Mistress, who sighed happily.

“You’re doing surprisingly good work, slut. But I thought you’d be better than this. Are you really so distracted?”

Rarity nodded, keeping Mistress in her mouth as much as possible.

The toy slid in far further. Rarity screamed into Mistress, who shuddered in delight.

“Not exactly skillful, or mindful,” Mistress said, “but that was definitely fun.”

Shining kept checking the ropes, squeezing Rarity’s throat with his magic to check her pulse -- delicious. Still, he seemed worried.

“You’re sure this isn’t too much?”

Mistress locked her knees against the side of Rarity’s head and ground into her muzzle, not letting Rarity’s head move an inch, forcing her tongue where it was needed. Even the job of pleasing her mistress had been taken from her.

She was just to be used now, and used well.

“I think I know what this bitch can take better than she does right now. She hasn’t even tried to tap out yet.”

“You do have the option, Rarity. I’m keeping an eye on you.”

“Love?”

“Yes?”

“You’re doting on my toy, again.”

“I’ve upset you, then. Should I come up and kiss it all better?”

Mistress purred. “Oh, yes, please do.”

Shining swung over Rarity’s stomach, letting his cock rest against her chest. He shifted forwards until the tip of it was pressed into the soft hollow of her jaw, felt the pre dribbling down onto her throat.

He grabbed Mistress’s hair, she felt that much, and pulled her hard into a kiss. They thrashed on top of her, Shining being careful not to let his weight press into her too much, Mistress mashing herself hard into Rarity, giving her no respite but for the occasional desperate breath.

Then Mistress took the toy and pressed it in all the way.

Rarity screamed into Mistress, her legs trying to curl back up into her chest but only pulling taut on all the ropes.

Too full too full too full too much.

Mistress pulled it out until only the tip was still in, holding her entrance spread wide. Still so much, but it would mean she wouldn’t have to be spread all over again... small mercies.

“Don’t be such a pussy, slut,” Mistress said, shifting back to grind on Rarity’s horn, “That wasn’t even as wide as my hoof. And I was considering that...”

Rarity whimpered, but she practically throbbed at the idea of that. Shining must have felt it, too, sitting where he was, because he didn’t try to chastise Mistress again.

“Maybe next time. I’m sure she’d be welcome back to play again. Twilight is very sharing.” Shining suggested.

Rarity twitched at that. Next time?

Mistress’s grinding slowed as well. “Truly?”

Shining must have nodded, because Mistress threw herself around him in a big hug and giggled.

“Well. Then there’s no need to... rush things like I was thinking then.” Mistress crawled off and lay down next to Rarity, tilting her to face her, look into her Mistress’s eyes. “If I get another chance to truly appreciate you, it might be better to wear you in than wear you out.”

That was an interesting proposition. Even through the pain and bliss and hormone haze, Rarity got the significance of it.

She was being invited back.

The toy was pulled out slowly, Rarity groaning the whole time as she was finally left empty, finally given a break. She was sore and throbbing, which made her feel sensitive even to the beat of her own heart.

Shining lined himself against her again. He’d seemed a little big before, but now after having been so thoroughly stretched... he seemed the absolute perfect size.

He stopped.

Mistress whispered in her ear. “You are not allowed to cum until you have finished both my husband and I. That means you might have to actually concentrate on me before you finish, because you’ve been getting very sloppy, addle-minded whore.”

Rarity nodded.

Mistress whispered again. “Actually, I might have to try that horn of yours. Such a smooth, round tip, and those interesting curves on it... that sounds fun. But you know what’s even better?”

Rarity shook her head.

Mistress nipped her earlobe, and Rarity squirmed. “It means you get to watch me and my loving husband make love over the top of you while we use you like the convenient cum receptacle that you are.”

Then Shining fucked her.

He’d been holding back before. Now, as Mistress slid down Rarity’s horn, making high-pitched, girly squeaks of delight the whole way, dripping down onto Rarity’ forehead and into her hair, Shining was rocking her hard.

With the ropes lifting her up off the bed, he had the exact angle he needed to force her down, the force of his hips meeting hers making loud creaks from the wooden headboards. The ropes weren’t giving, but the woodwork was beginning to.

Shining met his wife over the top of Rarity, pulling the back of her head into his and kissing her hard, and already Rarity began to see the bruises on her lips, the devilish and delighted smile.

Mistress laughed. “My, my. He’s being so much less gentle than usual.”

Shining snorted. “She doesn’t deserve it, does she?”

“No,” Mistress agreed, sinking down until she was flush with Rarity’s skull, rocking herself up and down against the sunken ridges of the horn, “the slut doesn’t.”

Rarity was too beyond breath to be able to scream. Her mouth was open, her jaw hurt from how much she was stretching it, but there was no sound. Like an agonized yawn, but for the two ponies using her.

And Shining had already cum. He had the stamina to last.

Rarity did her best to ignore him, and focused on Mistress. Tilted her head in ways that would afford her a better view of Shining and his muscled stomach, the taut muscles that rippled under his skin with every thrust... but also to press herself into the right spots, the places that made Mistress make the prettiest noises.

Mistress seemed to approve, and she upped the tempo. No longer pressing down to the bottom, but using Rarity’s horn to scratch itches in very specific places.

“How are you doing, husband?”

Shining grunted. “She’s still a tight little bitch, I’ll give her that. Nearly there.”

Mistress collapsed into his neck and started biting at it hungrily. She was enjoying herself but...

Rarity had an idea. More of an instinct, those pushed through the heat better.

Her horn glowed, already sending shivers up Mistresss’s spine, but she focused on her clit. A little spell she had taught herself for long, lonely nights... She buzzed it with just a little more force than Rarity herself adored.

Cadance sank down again, her legs going jelly-loose. “Oh, you BITCH!” she howled, half reprimand but half giggle.

Then Shining bit down on Mistress’s neck himself, grunted. Heaved a huge breath out of his nostrils like a charging bull. It had all been too much for him. He went primal, now.

His cock twitched inside her and he came.

The bite, the buzzing, the horn, all collapsed in on Mistress too. Either it was enough for her or, more likely, it was too much for her to hold back anymore. She screamed, delighted.

And finally, finally, Rarity earned her right to cum.

She went still, absolutely still, as every muscle in her body tried to tense at once. Especially fulfilling were the ones that gripped Shining like a vice and held him firm, pressed as tightly to him as possible until she could feel every ridge, every vein of his still-twitching cock.

Shining and Mistress kissed so deeply, holding each other tight, desperately babbling how much they loved each other between ragged, desperate breaths.

“And you,” Mistress said between heaving pants, “were a wonderful toy to play with.”

“Thank you, Mistress.”

Shining pulled Cadance down onto the bed and they snuggled into Rarity from either side, Shining pressed into her back, Cadance hugging into her stomach, resting her chin on the top of Rarity’s head. They made small, happy, contented sighs and noises, occasionally shifting to press more of themselves against each other, deeper into the cuddle.

This, this sincere, relaxed affection was almost as good as the sex.

Almost.

Shining kissed the back of Rarity’s neck, softer and more fluttering things. “We really would love to have you back sometime, if you don’t mind.”

“I’m sure Twilight would love the time with her niece.”

“And we do love the break...”

Rarity wasn’t capable of saying what she felt, or much of anything at that point, so she hugged them both tighter and hoped they got the message from that.

“See, if I push you harder,” Twilight pushed Flurry harder on the swingset, so she went even higher, “how long does it take now?”

Flurry waited until she paused all the way at the top of the arc before counting again.

“Un! Two! Tree!” Flurry was getting better at the ‘words’ thing, but the ‘thhh’ sound was still a little difficult for a pony who was still getting used to all their teeth, so she didn’t try that hard. Twilight, who had the firmly held belief linguistic prescriptivists deserved all the wedgies they got in college, didn’t bother trying to correct her niece because she understood her perfectly.

“Still three?”

Flurry burbled in agreement.

“So what does that mean?”

“Higher!”

Twilight swung her a little higher still, smiling. “Need more data, huh? You’re going to be such a good scientist when you’re all big. How long now?”

Flurry laughed, “Tree!”

“Still three?”

“Yes!”

“So what does that mean?”

“It’s a same!”

“Alright. So we know that how high you are doesn’t change how long you take to swing.”

“Woooah! Cause it’s longer, but I go faster?”

“That’s right!” Twilight couldn’t help but stamp her hooves happily, as long as she knew Flurry couldn’t see. She had to keep her sensible teacher voice on or she’d look ridiculous. “So what’s still the same?”

Flurry thought about that a bit.

“Higher!”

“Higher?”

Flurry seemed absolutely determined. “Hardest push!”

“Hardest? Are you sure-”

“Push!”

Twilight pushed Flurry with her magic right up until the point where the chain went slack at the top, and the frame juddered. Flurry looked absolutely crushed at the newfound limits to her height. Her little wings beat furiously trying to get... higher.

“More!”

“I’m not sure it goes any-”

“All the way around!”

Twilight was a good aunt, and absolutely did not do irresponsible things with her toddler niece. Unless her niece used her ‘I’m discovering things!’ voice. She had just used that voice now.

Twilight pushed Flurry all the way up, then back down... waited until she was at the height of the backswing and...

“Loop!” Flurry shouted in triumph, hooves over her head, as Twilight wrapped her once, twice, three times around the swing set, Flurry’s usual giggling replaced with... was that a cackle?

She was working on her maniacal laugh. Oh, kids just grew up so fast, didn’t they?

Flurry was swinging now, with about half the chain wrapped around the top of the swing set. She’d gone from her little hooves almost touching the ground to swinging at just about Twilight’s head height.

“One, two! One, two! One, two!” Flurry cheered happily, counting off. “Itsa chain!”

“What’s the chain?” Twilight asked, doing her best to sound suspicious and skeptical while she screamed happiness in her head.

“How long it swings is how long the chain is! I thought so.”

“And now you tested it. So a longer chain means...?”

“It swings longer. And shorter means less.”

Twilight wanted to rip Flurry out of the swing and spin her around and all sorts of things, but Flurry seemed to be having a lot of fun kicking around in her ‘modified’ swing set so that wouldn’t be fair to her, would it?

“I hope Rarity and your parents are having as much fun as we are,” Twilight giggled, “but honestly? I don’t know how they possibly could be.”

“Are they doing experiments with each other, too?” Pause. “Aunty Princess Twilight? Why are you bright red now?”

“I’ll tell you when you get your cutie mark.”

“Okay!”
