Complicated Relations

Lying atop her brother, Twilight moaned in pleasure. The long shaft of speckled stallion flesh in front of her glistened in the light of the overhead lamp; partly from Shining’s own precum, but mostly from Twilight’s saliva, which now coated every square inch. All the while, the white unicorn’s tongue caressed the smaller pony’s feminine folds, making occasional, and infuriatingly teasing, visits to her clit.

Twilight had had trouble sorting through the veritable spectrum of emotions vying for her attention in the aftermath of Shining’s revelation, but like the studious, reasonable mare she was, she had settled on the most logical one: Lust.

After a very brief chat with Cadance – who, as it turned out, had come home early and simply succumbed to curiosity – Shining had returned to the bedroom and asked Twilight if she wished to continue their “activities”. Typical male, Twilight had thought in response to the offensively brazen request. Yet her own answer had surprised her; despite the incomparable awkwardness of the whole affair, the surge of adrenaline that had shot through her had excited her. Or, perhaps, simply amplified the excitement she had been feeling. She had never considered herself a thrill-seeker before, but her body told her she needed release, and the opportunity was literally right in front of her.

It really was the logical choice.

A part of her was still angry with her brother for revealing their secret, and another for not telling her immediately that he had done so. And yet, she knew that one wasn’t supposed to keep secrets in a marriage; she should have been able to predict that Cadance would, sooner or later, find out. And Shining hadn’t lied to Twilight; he had simply been waiting for an opportune moment to tell her information that, while important, wasn’t urgent. And finally, no harm had come from his actions.

Well, none except the lump on her head, which was still aching a bit. It was a good thing that the other end of her body was providing something far better to focus on.

Logical, truly.

The purple mare also had to admit that she was no bastion of pure blamelessness herself. For all the excuses and justifications she could come up with, the fact remained: she had just tried to have sex with a married stallion behind his wife’s – her friend’s – back. She did not exactly have a moral high ground from which to spout her indignation.

Shining Armor, the blabbermouth. Twilight Sparkle, the homewrecker.

Mi Amore Cadenza, the voyeur.

Cadance puzzled the young unicorn. A typical wife would never permit her husband to have sex with another mare; much less his own sister. Out of anypony in the world, she should have been the most outraged; not to mention disgusted and betrayed. But, instead, Cadance knew and allowed – no; approved – what they were doing now. Shining had said so, and Twilight believed him. The two mares hadn’t directly spoken yet; that was probably rude, but by this point the rules of etiquette had become fuzzier than any of the animals Fluttershy kept.

Twilight wasn’t even sure if Cadance was still in the house. She hadn’t heard the alicorn leave, but then again, she hadn’t heard her come in in the first place.

As Shining’s practised tongue worked its way inside her, Twilight moaned – a lot louder than was necessary.

She was hoping that Cadance could hear her.

She redoubled her efforts against her brother’s cock, shoving as much of his impressive length down her throat as she dared, simultaneously working her hooves on the portions she couldn’t fit, and using her magic to gently massage his scrotum. She slurped, sputtered, and moaned again, lightly grinding her own sex against his mouth; inviting him to go deeper and harder into her heated pussy.

Maybe Cadance could hear her, wherever she was. The living room, perhaps. Or maybe just outside the door. The thought of being listened to – watched – left her feeling exposed and vulnerable.

And turned on.

Her relationship with her brother had been a tightly-guarded secret all their lives. That secrecy was a piece of armor she had worn for so long that she had forgotten it was there at all; it had become a part of her. Being stripped of it left her naked in a way she hadn’t thought possible. It was as if the most intimate parts of her soul had been put on display for scrutiny. It was humiliating and naughty and dangerous and offensive and so delicious.

She pulled away from the stallion’s shaft just for a moment, though a tenuous connection remained in the string of spit and precum hanging between her lips and the head of his member. Another moan; this one very strategic: It served to cover up any sound the bedroom door might make as Twilight pushed it open with her magic. She half-expected to see Cadance there again.

She wanted to see Cadance there again.

There was nothing. Just an empty, dull hallway.

She dove back down, positively assaulting Shining’s cock with her tongue, pressing it deeper down her throat, further and further until tears welled up in her eyes. Where reality had failed, her imagination would pick up the slack.

She thought of Cadance standing there, in the doorway. What would the young princess look like? Would she be pleased or disgusted? Calm or angry? Perhaps... titillated? Would she be happy that two ponies she loved were satisfying each other? Or would she be harshly scrutinising them; judging them?

Twilight wanted to be judged.

Her foalsitter, the pony who once had read her bedtime stories and kissed her scraped knees better, would watch the filly she had so diligently cared for, now proudly sucking down a stallion’s throbbing cock. She would stare in awe as that precocious, innocent child writhed in ecstasy, the stench of sex heavy in the air around her, sweat glistening on her coat, her tongue hungrily lapping up primal male essence, her marehood bursting forth its victorious juices as she shamelessly claimed carnal pleasures so obscene that thousand-year-old princesses would blush at the mention of them.

Her brother’s wife; caring, loving, and doting; would see her rightful beau succumb to the will of another mare; her storybook marriage twisted and perverted as that interloper in her bed would make the stallion cry out in ways she never could, stealing him away like a piece of property. Her virtuous husband would give himself over completely to the one who gave him more; deserved him more, forgetting his vows in exchange for the licentious feast that was the younger pony’s body and the heaven that was her covetous mouth.

And Twilight would brazenly look her right in the eye as they both orgasmed, as if to say, “He’s mine. What are you going to do about it?”

It was too much.

Twilight had lost control of herself and, with a flick of Shining’s tongue, the pent-up energy within her released in a mind-and-body-wracking climax. She actually screamed. She had never screamed during sex before. If Cadance was somewhere in the house, there was no way she wouldn’t hear that. Electricity surged through every organ and limb in Twilight’s body, and her every muscle tensed and twitched. Her mind could no longer distinguish between right and wrong – nor between apples and quills, for that matter. All thought had left her, and only pure ecstasy remained.

The stallion eagerly drank from the veritable fountain that her pussy had become, spilling not a single drop of the mare’s orgasmic liquid. Lost under the thrashing of his sibling, his own chest was rocking gently in silent laughter.

As Twilight came down from her high, she noted that her brother hadn’t cum along with her. A problem easily solved, she concluded. Before the full force of sexual exhaustion could hit her, she grasped his shaft back in her lips, and threw a few rings of pleasurable magic aura around the base for good measure. He had been close to the edge already, and it took only a precious few seconds for his orgasm to follow. Twilight swallowed all that he gave her, continuing to work her tongue around the head of his cock through his climax. She let the final few spurts land on her tastebuds, allowing her to savour her brother’s ejaculate.

The flavour was sweeter than she remembered. Her academic mind, now returning to a more-or-less normal state, offered up the interesting fact that the taste of semen was highly dependent upon diet. She turned herself around so that the two ponies were lying face-to-face, commingling their exhausted breaths, and resisted the urge to ask Shining what he had been eating recently. Some topics were just too nerdy, after all.

They shared a kiss, tasting themselves on the other’s lips. The white stallion ran a hoof along her cheek, brushing away a lock of her mane, and the two siblings gazed into one another’s eyes.

“So,” he said with a teasing smile, “can you tell that Cadance has been feeding me health food?”

Again, it was too much.

Already spent, Twilight’s body somehow rallied more energy into an explosion of laughter. She could no longer keep track of how many times she had released tears that day. She didn’t mind; most of them had been tears of joy.

“Yeah, I can imagine,” she finally answered. “She’s really a wonderful pony, isn’t she?”

“The best,” Shining replied with a contented smile. After a few seconds he realised what he had just said, and his eyes went wide. “Along with you, I mean!” he covered quickly. “You’re the best sister anypony could have. She’s the best wife. The two best mares in Equestria! You’re both the best, and I’m the luckiest stallion alive to have the two of you, who are the best ponies ever... I mean, if there was ever a contest, you’d both be... I mean, you’re both tied... for best...”

His face had turned crimson by this point. He tried desperately to formulate an escape from Twilight’s scornful glare, and finally settled on a daring and ingenious plan well-befitting a pony of his skill and bravery.

“I love you,” he mumbled sheepishly.

“Hmph,” Twilight turned her nose up, doing a passable job of mimicking Rarity’s ‘offended lady’ affect, “is that why you decided to keep the truth from me and trick me into giving your voyeur of a wife a perverted show?” She hoped he couldn’t see how hard she was struggling not to collapse into laughter again.

“I swear by Celestia I didn’t know Cadance would be here!” he protested. “I really thought we were alone. I was planning for the three of us to talk about everything over dinner tonight.”

“Likely story!” she accused, but no longer had the energy to keep up the façade; she began snickering.

Seeing that the immediate danger had passed, he moved in closer, putting his forehead to hers, crossing their horns in a gesture of tender intimacy.

“I love you, Twiley. So much. And I love Cadance. I really am the luckiest stallion alive and... I don’t think I deserve either of you. I know I didn’t earn it. You have no idea how happy I am that I don’t have to hide myself from either of you.” He sighed blissfully. “You two will get along great. I know it.”

“We already do,” Twilight reminded him, giving a pleasant sigh of her own. “I really like Cadance. And I’m glad I don’t have to lie to her, either.” She scrunched up her nose in thought. “But now that I know that she knows, I’ve been having some... strange thoughts about her. Not bad thoughts, just... strange.”

Shining Armor eyed her curiously.

“I know what you’re thinking,” she warned with a dangerous frown. “Don’t get any ideas.”

The fake halo was almost visible above the stallion as he affected pure angelic innocence.

“She and I have a lot to talk about. Mostly you.” Twilight glowered briefly, then relaxed and looked thoughtfully off to the side. “But we’ll both probably have to start off with some apologies.”

“Dinner’s in two hours,” Shining said simply, looking at a nearby clock.

His sister gave a light chuckle, before her expression turned somber. It was as if dark rainclouds were suddenly collecting to block out the light in her eyes. “When I found out you were marrying her, I...” She choked on her next words. “I didn’t want it to be true.”

The stallion pulled back, surprise and confusion painted on his face. “What are you talking about?”

“I thought that you getting married meant that... that I would lose you. I was jealous. I realise that now.”

“Twiley...” he began, but was silenced by a purple hoof to his mouth.

The mare shook her head, adamant about finally laying her feelings bare. “I didn’t want you to marry her. From the moment I got that invitation, I was looking for any excuse to stop it. Even after I found out you were going to marry Cadance, the best pony I could think of for you... I tried to find fault with everything she did, and I convinced myself that she was evil, even though there was a reasonable explanation for all of her behaviour. I tried to stop the wedding because I thought she was going to take you away from me.”

“But you were right,” Shining Armor said, “that was the changeling queen, and she was evil.”

“But what if it hadn’t been a changeling?!” Twilight’s eyes filled with tears, in what was quickly becoming a running theme that day. “What if it had been the real Cadance from the start, and what if she had just been stressed by the wedding, and using her magic to heal you, and got rid of her bridesmaids because they were being nasty?”

Her brother could only look on, stunned.

“Don’t you understand? I thought that was Cadance. Even if she wasn’t real, my feelings about her were. When I came into that wedding rehearsal, I meant every word I said... and I almost lost you forever. That wasn’t the changeling’s fault; she didn’t make me say those things. It was my fault.” Twilight sobbed. “I was trying so hard to hold onto you that I pushed you away. I was so possessive and selfish... I nearly destroyed our relationship.”

Shining pulled his sister into a tight embrace, and began gently running a hoof down her withers. “Listen to me. You didn’t nearly destroy our relationship. And you definitely didn’t almost lose me.” He nuzzled a purple ear comfortingly as he continued to caress her back. “Twiley, we just had a fight. Brothers and sisters fight all the time.”

“But we never did,” she whispered, still crying.

“Well, there’s a first time for everything,” he said with a hint of amusement. He pulled away so that he could again look directly at his sibling. His mouth offered a soothing smile. “Do you really think that I would throw away a lifetime of love and friendship because of one argument? I may not be the sharpest sword in the armory, but come on, sis, give me some credit.”

“You told me that you didn’t want me at your wedding.”

His smile died instantly at the reminder. He thought for a few seconds before speaking again. “Sometimes,” he tried uncertainly, “when they’re angry, ponies say things they don’t really mean.”

“Did you mean it?” Twilight asked. Seeing his hesitation, she added, “Don’t lie to me.”

With his eyes, he told her that he wouldn’t. “I was very angry,” he said after a while, “I thought you were hurting Cadance. I guess... I really did mean it... at the time.”

Her tears continued to flow, and much like he had done earlier, her brother kissed them away.

“But no matter what I said or how angry I got,” he continued, “I never stopped loving you. Not for a second. I’m your B.B.B.F.F... and I shouldn’t have to remind you what that last ‘F’ stands for.”

Twilight wept softly into his chest. Shining Armor continued to stroke her gently, his muzzle buried in her mane. Though these final, hidden doubts had pressed against the corners of the younger unicorn’s mind ever since the wedding, she hadn’t known until now just how heavy their festering burden had been. It was as if a thick sludge had been coating her soul and was finally being washed away.

“What would’ve happened,” she asked once a degree of control had returned, “if there had been no changeling? If I had said all those things about the real Cadance?”

The larger pony smiled, lifting his sister’s chin up. “You really want to know?” His voice was filled with sage confidence. “I’ll tell you exactly what would have happened: We would have apologised to each other and made up. And you would have been my best mare, just like it happened in reality.”

Twilight was stunned. The answer was almost artificial in its straightforwardness, and yet it really was just that simple. She knew it was the truth. Mere moments after their spat at the rehearsal, she had been ready and willing to beg for forgiveness, and there was now no doubt in her mind that she would have received it immediately – had a certain insectoid villain not interfered.

Shining Armor would always forgive her. It was written all over him, plain as ink on parchment, and Twilight chastised herself for somehow having failed to see it before. Even if – when – she hurt him, he would not toss her away or forget her. He would always love her.

She had always known that.

Or had she?

It didn’t matter. She knew it now, and the thought of it made her heart soar. She felt happy. Happy and tired. The physical exhaustion of her intense orgasm just minutes before now combined with the resolution of an emotional climax to leave her utterly spent. There was only one logical course of action.

“Two hours?” she asked.

“Huh?” the white unicorn cocked an eyebrow in momentary confusion. “Oh, yes! Just about. Cadance said she’d be making something really tasty for all of us.”

“Mind if I take a nap until then?” she said, snuggling into the larger pony’s chest.

Her brother’s voice answered, but his words never registered in the younger pony’s mind. She was already asleep.

Shining’s own eyes closed soon afterward.

A few minutes later, a soft and warm blanket, carried by a pale blue magic aura, gently covered them both.
