Middle-Mare

"Thanks for looking after Flurry again for us," Shining Armor said. "We've been so busy making sure the Crystal Palace is ready for the delegates summit. We really appreciate you getting here early to help out."

"Of course," Twilight Sparkle replied. "The best aunt ever always looks forward to spending more time with her!"

Cadance smiled. "That's how I know you'll be the best mom ever one day too." Twilight's smile softened slightly. "I know I don't have to remind you, but please let us know if there's anything you want while you're here as our guest in the empire."

Twilight glanced at Shining and then looked back at Cadance. "Yes, thank you, of course."

They smiled and turned to leave. Cadance leaned over and kissed her husband on the way out.

That evening, Princess Cadance sat by the fireplace in the den of her palace suite. She swirled the dark red drink in her crystal goblet, enjoying the quiet of the night's small hours. There was a knock at her door. "Come in."

Twilight Sparkle walked inside. "You wanted to talk to me about something?"

Cadance nodded and motioned to the plush seat across from her to sit. "There is. But first..." She poured her a glass of wine. Twilight sat but hesitated. "It's not bitter, I promise." Twilight took a small sip, indeed finding it to be more sweet than she was used to for wine. Cadance waited for her to become more comfortable before continuing. "The Crystal Empire has so much more to offer you than just the library, Twilight."

"I know that."

"I have an entire task force of staff at your beck and call. Palace Chefs who have gone to years of culinary school to create masterpieces, so much more than the meager daisy sandwiches you ask for."

"Well, I don't want to be a bother..."

"The masseurs' in the palace spa may not be unicorns, but you'd believe they have magic in their hooves."

"I don't need that, really."

"The Crystal Bards troupe-"

"Cadance!" Twilight snapped. Cadance paused and sipped her wine. "I'm sorry," Twilight apologized. "I know there's all these things here but I just... I'm just not used to the idea of being served on."

"You mustn't think of it that way, Twilight. These ponies... They're not slaves. They get paid very well. And moreover, they chose this job. They competed fiercely for the opportunity to show off their talents for you." Twilight looked at her. "Yes. You have fans here, Princess. They want so much for you to let them impress you."

Twilight put her hoof to her chest and took a deep breath. Then she exhaled and pushed it away, pushed her worries away, and blew away her anxiety. After a moment she nodded in frustration. "I... yeah, okay, I get it. I will... try to do that."

Cadance gave her a soft smile. "I know you like to think you're above getting stressed out nowadays. But you're only fooling yourself. And I need you to have your head in the game for the summit later this week. What's the first thing I taught you about negotiating?"

"Leave emotion at the door."

Cadance chuckled. "Okay yes, that actually is the first thing. But I meant once you're actually at the table."

"Negotiate from a position of power," Twilight recited.

"Precisely! Twilight, these ambassadors... they can smell fear. They've been trained to. If you show any kind of weakness, they'll eat you alive."

"You have a strange way of trying to help my anxiety."

"I didn't ask you here tonight to blow sunshine up your ass. I'm trying to make sure you've got your shit sorted out. So let's figure out what you need for that to happen."

Twilight winced, but only for a moment before she nodded. She was no stranger to Cadance's tough love when she needed to hear it. She shrugged and looked down at her drink. She finished her drink and set the empty glass on the table between them. "I don't know. I'm a princess! What could I possibly need?"

Cadance swirled her own wine and also finished it. "Okay... Let's take a step back. Maybe need is a strong word. What do you want?" she asked. Twilight looked away at the fireplace. "What do you... desire?"

And there it was.

Twilight felt her cheeks getting warm. Was it the fire? No, not for just her face. She was flushed. Was it the wine? No, not the wine either. It was a blush.

Cadance could feel the short hairs standing on the nape of her neck. She poured two more glasses and leaned back in her seat. "You know, Twilight, I've never seen you happier than when you're with Flurry. I understand that joy. And I do remember that want, that need... to be a mother."

Twilight's eyes glistened before she quickly blinked it away.

"You know... as royalty, your marriage could be a very powerful bargaining chip. Prince Abraxas of Zebrica will be at the summit. You know what they say, once you go striped..." Cadance joked. Twilight either ignored or didn't hear her. "Queen Rain Shine's son is only a little younger than you... I do hear the Kirin are quite fiery lovers..." Twilight remained unmoved. "I did catch wind of a rumor from Mount Aris that Sky Beak finalized his divorce..."

"No," Twilight said at last.

"No? Will there be somepony else there that you had in mind?" Cadance asked.

And there it was.

Twilight tried to cool the warmth in her cheeks with more wine. She glanced at Cadance from behind her wine glass.

Cadance smirked back at her. "Come now, Twilight, you really must learn to not make it so obvious."

Twilight nearly choked on her drink. "W-what!?"

Cadance rolled her eyes. "I've known you for most of your life, Twilight, I'd have to be blind to not notice. I didn't even need to use my love magic."

"I... I don't know what you're talking about!"

"Lie to yourself all you want. But don't lie to me about this! It's insulting to both of us."

Twilight's lips trembled as her composure broke. "W... when?"

Cadance scoffed. "Where to even begin!? From the first time you caught us playing spin the bottle and every time I kissed him afterwards. I could feel your eyes on me, burning with jealousy. The wedding. The baby announcement!"

And there it was.

Twilight felt herself bristle. She looked at Cadance. Cadance just nodded at the fur standing up on Twilight's limbs. Twilight looked at the floor. "Is it really that obvious?"

"No," Cadance assured her. "Just to me. It's my special talent to notice such things. Like the way you glance at him whenever you think I'm not looking. The way your eyes linger on his body far longer than you mean to. The way you carry your tail just a tiny bit higher when he's in the room."

"Okay! I get it!"

Cadance sipped her drink. "Twilight... do you hate me for marrying him?"

"No, of course not!"

Cadance looked over her face. There was no lying there. But... "Do you hate yourself for the way you feel?" Twilight's mouth opened, but no words came. "You shouldn't," Cadance added quickly. "You've done nothing wrong. And we don't get to choose who we fall in love with. And believe me, I know."

"Does he..."

"No. He has no idea. Don't worry."

"I meant..."

"Oh. No, I'm sorry Twilight. He doesn't feel that way about you." Her horn glowed for a moment. "I checked."

Twilight glanced at Cadance's horn. "Could he? I mean, could you... with your magic?"

Cadance frowned at her. "You would ask that of me?"

Twilight looked at the floor in shame. "No. It wouldn't be fair to him."

"No pony should have that power."

They sat there with nothing but the sound of the dying fire for a long while.

"I'm sorry, Twilight," Cadance said, drinking her wine. "I really am. I know how it feels to love somepony who doesn't love you back in the same way."

Twilight looked at her in confusion. Cadance looked back at her. Twilight looked at her, looking back at her, and saw her, as though for the first time, not just the mare who married Shining. She felt her stomach flutter. "Cadance?"

She nodded.

"But... but I don't even like mares that way."

Cadance just smiled softly. "I know, Twilight. I know... But I do. Just as much as I like stallions. And as surely as I love Shining. And had things been different, I might just as soon have married you."

"Cadance, I... I don't know what to say... I'm sorry?"

Cadance shook her head. "Don't be. As I said, you don't get to choose who you love. And neither can I."

"But couldn't you..?" Twilight motioned to her horn.

Cadance shook her head. "No, Twilight. I can only remind ponies of their love. I can't make them feel a romantic love that was never there in the first place. Even if I wanted to." She leaned over and put her hoof on Twilight's leg. "And I did want to, Twilight. So very badly."

Twilight looked down at Cadance's hoof on her and swallowed hard. "Am I... Is that how you know you can't?"

Cadance nodded.

Twilight sat in wonder for a long moment. "Had things been different..." she trailed off. "What about Flurry Heart?"

Cadance sat back and smiled. "Oh, I'm sure we would have still had Flurry." Twilight raised an eyebrow at her. "Twilight, two halves can't make a whole without a pole. Even if I didn't outright marry him along with you, he would still have been my first choice for a sperm donor."

Twilight snorted. "Yeah... Me too, I guess." As quickly as it appeared, the smile ran away from her face. "But we can't always get what we want, can we?"

Cadance's expression turned serious. She drank the rest of her wine and threw the glass to shatter into the fireplace. "Not with that attitude! If you want something bad enough, you negotiate for it!"

"What are you talking about?"

"You want Shining Armor for your sperm donor?" Cadance asked as she grinned. "I can make that happen!"

"So... what's the catch?"

Cadance smiled. "Well, now... I have something that you want... to make a deal." She stood up and walked around behind their chairs. "Therefore, there must be something that you have... that I want... to make a deal. And it just so happens that there is something that I want." Twilight felt Cadance's hoof on her shoulder. "Something that I have wanted for a very long time."

Twilight swallowed nervously. "But Cadance, I'm straight."

Cadance leaned over and whispered into her ear, "So is spaghetti until it gets wet." Her horn glowed. A pulse of her magic radiated out and washed over Twilight's body with a tingling warmth before it settled into her lower abdomen. It didn't quite make Twilight orgasm, but one could be forgiven for thinking so from the way the younger mare reacted, and the dark patch of dampness spreading into her seat cushion.

"That's a neat trick," Twilight breathed.

Cadance almost looked indignant for a moment before she grinned again. "Tricks are for street whorses. And I don't need magic to make you feel wonderful." Cadance's hoof drifted lower along Twilight's body. "By the time I'm done, you won't even want Shining anymore."

Twilight bit her lip and shifted uncomfortably in her seat, squeezing her thighs together in a vain attempt to stem her leaking pussy. "No, I don't want that. I just want him."

Cadance's smile softened. "A pity. But no matter. I can still get what I want." She walked back over to her chair and settled in lower, letting her butt slide forward to the edge of her seat and she spread her legs. "Well? Go on then!"

"What?"

Cadance just rolled her eyes. "You've told me what you want. And I've made it quite clear what I want from you in exchange." She pointed at her marehood.

"But I just told you that I don't want to do that," Twilight said.

"I know. But that's what gives it value in this exchange. Aside from my own intrinsic enjoyment of it," Cadance explained. Twilight pursed her lips. "I won't force you to do anything, of course. But then, I don't have to give you Shining's semen, either. Be my mare tonight, and you may have his seed in the morning." She held her hooves out. "Those are my terms. Take it or leave it. So, do we have a deal?"

Twilight chewed her lip as she considered it. Changing teams for one night to finally have the foal she always wanted. After a long minute, she nodded.

"Well then..." Cadance motioned to the floor in front of herself.

Twilight slowly got up from her chair and walked over to Candance and knelt down in front of her, clinically examining the other mare up close, the way a foal winces at a plate of brussels sprouts.

"Here, why don't we start with something easy?" Cadance suggested, holding the back of Twilight's head with her hoof to move her up away from her crotch to her teats. "Start here. This you are familiar with, yes?" Twilight raised an eyebrow. "I know for a fact that you were teat-fed as a foal. Shining told me about it at one point. I recalled sensing some intense jealousy over it."

Twilight balked. "What!? Shining has the hots for Mom?"

"You're in no position to pass such judgment. And no, it was not a sexual jealousy. It was a typical, juvenile jealousy of the attention you were taking away from him as the new foal. However, the more pertinent issue is that Flurry was last fed several hours ago and they're now quite heavy with milk. So, if you would be so good?"

Twilight held one of Cadance's teats with her hoof and gave it a gentle squeeze, causing a small stream of her milk to squirt out. She gave it another squeeze and more milk came. Cadance slapped her hoof away. "I didn't mean for you to milk me like a cow! Don't be so wasteful!" She pulled Twilight closer.

She got the hint and leaned forward to give her teat an experimental lick. Her milk was much more heavy, creamy, and sweeter than Twilight's usual soy coffee creamers. She gently kissed her nipple, taking it into her mouth with the slightest suck. Cadance's hoof on the back of her head pressed Twilight's face into her plump teat, flooding her mouth with her milk.

Twilight's head shot up with a worried expression and her cheeks ballooned out.

"Don't you dare spit that out!" Cadance scolded. "If you want Shining's milk inside you tomorrow, you need to take all of mine first! I want to sleep tonight knowing you have a belly full of me inside you!" Twilight winced and swallowed. It was actually quite good. "Now get the rest."

Twilight went back to suckling Cadance's teat. With a lecherous grin, Cadance watched Twilight's throat flex each time she swallowed more of her milk. Her hooves carefully pawed her teat, gently massaging and squeezing the rest of her milk out. "Good. Now empty the other."

Twilight did as she was told, suckling the other teat just as she had done the first. Cadance's magic glowed underneath her, sneakily playing with herself as the other mare nursed on her, a duet of pleasures. A small tendril of her magic teased her clit and another larger one pushed inside her marehood, pressing against that one spot inside in just the right way. She quickened her pace, feeling a different pressure building as Twilight finished swallowing the last of her milk from her other teat.

At the last moment, Cadance's hips bucked in orgasm, and Twilight's surprised face got sprayed with syrupy gushes of Cadance's mare cum.

Twilight grimaced. "It went up my nose!" she whined.

Cadance laughed. "Now get in there and lick it until you love it!" Her magic pulled Twilight forward again, with her mouth cupping Cadance's vulva. Twilight did as she was told, nervously at first. Cadance stroked her mane and looked down at her with adoring eyes. Twilight looked up at her from between her legs. "Do you have any idea how long I've fantasized about this? How many times I've rubbed one out imagining how you'd look between my legs like this?"

Twilight couldn't talk with her mouth full.

Cadance just looked at the object of her affection with her muzzle buried in her marehood, feeling her tongue attempting amateur cunnilingus. She thought that as a mare she would at least know what would feel good for another mare. Cadance pressed Twilight's face into her pussy a bit more firmly, rubbing her nose against her winking clit to give it some stimulation before just seeing to it herself with her hoof. Her breathing quickened. "Oh yeah... OH YEAH!" she moaned louder as her hoof moved faster. The pressure built up inside her quickly. Twilight could tell she was getting close to cumming again. "Oh yeah, this is gonna be a big one!"

Twilight tried to pull away, but Cadance's thighs clamped down on the sides of her head. "F-FUCK!" Cadance cried out as she came even harder. Twilight tried to squirm away but the older mares thighs had a firm grip on her. Twilight felt Cadance flooding her mouth as she squirted. She snorted panicked breaths through her nose as she felt her mouth filling to capacity, but Cadance didn't let go.

"Spitters are quitters!" Cadance said between her moans. "Your brother's no quitter. Are you!?" Twilight was unconvinced. Cadance gently put her hoof over Twilight's nose. Her eyes went wide with panic, unable to breathe. "Swallow it!" Cadance commanded. Twilight winced and Cadance almost immediately came again watching Twilight's throat flex. "Open your mouth." Twilight opened her empty mouth, showing Cadance that she had swallowed all of it. "Good girl. Now, over there," Cadance directed her to the full length mirror on the far wall. Twilight got to her shaky hooves and walked over to it.

Twilight felt Cadance's hoof on her shoulder, pushing her down onto her knees on the floor in front of the mirror. Twilight watched the reflection of the other mare step over her. Cadance reared up to lean against the mirror with her hoof. Twilight looked up but Cadance held her head still as she sat down on Twilight's horn, burying it inside her dripping vagina.

They both looked in the mirror at Twilight wearing Cadance's pussy like a hat. Cadance pet Twilight's forehead with her hoof.

"Don't you see now that this is where you belong?" Cadance said, stroking Twilight's cheek. "I can't tell you how many times your brother has kneeled right where you are now with his horn inside me just as yours is." Cadance moved her hoof to her pussy and started playing with her clit, rolling her hips slightly, feeling Twilight's horn inside her. "You'll learn as he did that your place, your purpose is to serve me. To please me. He can tell you first hoof how well I take care of mine." Twilight furrowed her eyes. "Your defiance only makes this hotter for me. But rest assured, by tomorrow, you'll be begging for me to let you put your tongue in my pussy!"

Cadance's magic started to play with Twilight's marehood. Twilight pursed her lips. "Now, now... Didn't I say that I'd take care of you? Do this one last thing and I'll give you what you want. I want you to close your eyes and think about Shining Armor while I play with you." Twilight did as she was told and closed her eyes. A tendril of Cadance's magic slipped inside her. "I want you to focus on your lust for him." Her magic morphed and shaped itself into a stallion's dick. "I want you to feel your taboo love for him with all your heart." The ephemeral dick started fucking her. "I want you to imagine your brother's dick inside you right now."

Twilight started panting. Cadance could feel the love energy inside Twilight coalescing up into her horn. "Yes. That's it!" Cadance coached with her hoof moving faster on her own clit. "Let it all out!" Twilight bit her lip in frustration, teetering on the edge of a climax just out of her reach. And then Cadance said the magic words, "Cum for your big brother, Twilie!"

Twilight's entire body shuddered as she orgasmed. Her horn went off inside Cadance as she came, filling her pussy with arcane energy that made her entire body tingle. "Yes! YES!" Cadance cried out as she came too, spurting out around Twilight's horn, drenching her mane as she squirted even more mare cum.

Her magic fizzled out and Twilight slumped down and out of Cadance's dripping pussy. The younger mare looked like she just stumbled inside from a downpour.

Cadance tried to gracefully land on the floor beside her. "Now, do exactly as I say, and I will promise you your brother's seed..."
