A Dose of Amnesia

"Th-thank you for picking me up, Shiny..." Twilight faked a hiccup, stumbling a little more than was necessary as they exited the crowded bar, Twilight leaning her weight on Shining. "You're the best big brother I could ever ask for..." She made sure to slur, to let the words carry themselves away lightly and of their own accord. It made it sound as if she had little wherewithal of what she was saying, of what was happening around her.

In truth, she'd only had two cocktails and a cider. Shining didn't need to know that. "Whoops!" She fell to the side, away from him, landing on the cobbled path and rolling onto her back, kicking her hind legs up and waving her tail back and forth. "They really ought to watch where they put those..."

She knew she was giving him a view, she absolutely knew that the movements of her tail were exposing her down below. She'd read books on pony attraction, seen it in action, and she was certain that she was displaying all of the signs of a drunken, horny mare, even down to the scent.

"Come on, Twily, let's get you up," he grunted, pulling Twilight back to her hooves with a strong, masculine foreleg.

He didn't even look! It was right there, so obvious that she might as well have begged him to take a peek, yet he was as platonic and chivalrous as ever! Ugh! Twilight forcibly bit back a growl. She walked with stumbles and heavy hooffalls down the street, being sure to rub into her brother as much as physically possible as she went. He barely seemed to notice, almost as if concern for her safety was drowning everything else out.

What was wrong with him?! Any other stallion would have jumped her by now, she was sure, but not him, never him! She'd tried everything by now, using his shower, walking in on him as he was bathing, walking around the house in lingerie, masturbating loudly at night in hopes of drawing his attention...

Yet once again, there he was, stalwart and looking forwards as if none of this phased him in the slightest. Worse, as if he didn't even notice it, let alone acknowledge it! "Shiny..." Twilight put on her cutest, most inquisitive voice, one that she hoped would drag him back to memories of when they had both been young. "There was a colt in the bar earlier, and he was really rude to me."

This got his attention. He turned, instantly perturbed, stopping and looking straight at her. "What happened, Twily? What did he say? Are you alright?"

Twilight forced her lip to quiver a little. She'd never been very good at fake crying, but the precursors to it weren't all that difficult to emulate. "He said..." A sniffle. Drawn out silence as she looked her brother dead in the eyes, exuding vulnerability. "H-he said that I have a really big plot, and that I look silly because when I walk it jiggles about and..." She blinked rapidly, looking back at her own hind quarters. "Do I have a big plot? Was he telling the truth? Does it look bad?"

Shining lightly tussled her mane, drawing her in for a hug. Twilight sniffed his coat without second thought. "Don't you listen to any silly colt from the bar, Twilight. You're beautiful, and I don't want you ever thinking anything else. You're my special little sister, you know that. I'd never think you were anything but. Try not to worry about drunk, jealous colts."

Gods, he was good. He'd managed to in a roundabout way answer her question without being dragged into any discussion regarding the specifics of her body, and he knew it! He was avoiding this so blatantly, it drove her insane! Thanks for nothing, made up colt from the bar.

Alright, last ditch efforts, think of some, and squeeze him a little while he's hugging you like this. Twilight could never get enough of the feel of her brother's body, after all. Hmm... maybe that was it. Yeah, she'd just keep rubbing at him, tightening the hug and pressing her body against his, that'd have to work!

"Anyways, Twily, it's getting pretty cold, we should probably get home already."

Twilight nuzzled into his neck, being sure to keep her lips just close enough that they might occasionally brush against his fur. "No... I'm warm here with you. Please just hold me a little longer, big brother?"

"If it'll make you feel better," he chuckled, ruffling her mane again before giving her a pat on the back. They were such typical brotherly things to do, and while it still felt wonderful, would it really hurt him to just nibble on her ears, or run a hoof over her belly, or kiss her on the lips for a few seconds?

Surely that wasn't asking too much. Twilight was eighteen now, about ready to embark on the next chapter of her education, and with Shining a guard in training, the time they got to spend together was only decreasing. She wanted to hold him all night, she wanted to hold and never break her grip, but she knew it would come to a close eventually, as all of their brotherly, sisterly exchanges did.

She needed something to keep him along for the ride. It was getting to the point where a final effort might have been the only thing between never having him, and having him for life, and with a reluctant but nonetheless present energy that pattered in her anxious heart, Twilight moved forwards once more.

She kissed Shining's neck, her lips only lightly brushing him at first. He didn't react, not one bit, and with her libido as a guide, she repeated the motion, the kisses quickly transforming into the soft and tender ministrations of a passionate, inexperienced lover. Still, Shining said nothing, but she could feel his muscles beginning to tense.

Was... was he really letting her? It felt like a dream, this perfect moment, everything she'd lusted after finally about to come true if she could only hold onto it, and with another push, she parted her lips, allowing her tongue to trail across his neck, causing him to shiver. She could feel her body beginning to buzz with an unreal excitement at the prospect of what might be about to happen alone, and she could barely contain her want, no, need to rub at herself long enough to ensure that she was still giving Shining the attention he deserved, the kisses and licks and nips she'd wanted to share for her entire life...

And then Shining flinched away, and Twilight's hopes crumbled to a dust that floated away on the night air. "Twilight, I think you've drank too much... You don't know what you're doing." He sounded resolute then, not even a hint of hesitation in his voice, and he walked on without another word. He beckoned for her to follow, but his mien wasn't inviting as much as it was frightfully indifferent.

But Twilight couldn't have that. She'd come too far, too close to tasting what was always beyond her reach, she needed to have more. Tonight could still be the night! She just had to convince him, no—she jogged after him, motions erratic and slightly panicked, cutting him off before he could walk too far. "W-wait, Shiny!" Her ears were pinned back, she was sure she looked as cute as heck right about then, but Shining's conviction didn't falter, not yet. "It wasn't a mistake. I do know what I'm doing. I was... showing you just how much I care for you."

"Twilight." There was already a scolding tone to his voice, bad start. "There's a word for what you were just trying to do, and you know what that word is. We can't do that, no matter how mixed up you're feeling right now, how drunk or out of your mind you are.... we can't. Not ever."

It was like having your dreams screwed up and thrown away before your eyes. "No, Shiny, you know that you'd like it... How couldn't you? I've seen what you've got in your magazines, you know," Twilight shot him a wink, but it only seemed to make Shining look more uncomfortable. He groaned, rubbing his eyes with a hoof. "I could be just like those mares, if you let me. Don't you want to lose your virginity, big brother? Who better to take it than somepony that knows everything you could ever want in a mare?"

"Twilight!" He turned away from her, a blush on his face. "We're not having this conversation. Not now, not ever. Follow me, I'm taking you home."

Twilight tried to speak to him a couple more times on the way back, but he didn't say a word. Truly, it was as if someone had taken Shining's soul and animated a statue to walk in his place. If he acted that way as a guard, he'd soon be captain.

But Twilight felt torn, borderline hysterical. After every subtle indication, growing more and more bold with time, the moment she'd finally made a move, she'd been rejected so easily? Did he really not find her attractive, not in the slightest?

When they finally got home, Shining said a few words to her before disappearing into the kitchen. He cleared his throat, and chose his words carefully, slowly, as if he'd been mulling them over for a long time and had calculated everything he wanted to say. Twilight had never seen him act so meticulous. "Twily. I love you. You know I love you more than anything in the world, and Celestia knows I would kill for you, die for you if I had to. You are and always will be the most important mare in my life..."

The words made Twilight smile beside herself, but his next sentence dashed the feeling completely.

"But we can't do that. We can never do that. We can't even think about it." Shining rubbed the back of his neck, looking to the floor. "Honestly, I should have said something sooner. I always had the impression that you had some kind of... interest in me, ever since we were young, but I suppose I hoped it would be something you grew out of... You understand why it's wrong, don't you?"

Twilight stopped short of a reply, her mouth open in a wordless gasp. Eventually, syllables managed to squeeze through, conflicted and forced out. "You... you knew?"

Reluctantly, Shining nodded. "For a long time, I always thought it might have been true, but I hoped it wasn't. I love you, Twily, but not like that. Never like that. It just wouldn't be right, not for either of us. This doesn't change anything, though. You're still the best sister I could ever ask for, but I really, seriously have to ask you to stop thinking about me that way. I don't know if that's hard for you, but you have to. We're not kids, anymore, Twilight. You'll find a stallion, you just have to go look." He went to bring her in for a hug, but seemed to think better of it at the last moment, faltering. "Just... just come to me if you need to talk. We'll work it out. Anyways, I'm gonna, uhm—"

Twilight broke the sentence for him, helping him out of the predicament. "Go. It's fine, honestly. Go and get some rest. Thank you for picking me up, and I'm sorry for all of this. I love you too."

As he left, Twilight very calmly walked up to her room. She opened her door and walked through, the picture of serenity. The moment she closed the door behind her, tears began to fall.

He just didn't understand how right for her he was! She'd always been able to appreciate other stallions, but the thought of him, it had plagued her mind for so long... and for him to turn around and say no, that it could never work?

Twilight couldn't deal with that. She just couldn't. She'd made a move on him, a clear, obvious move. Maybe she could explain it away, blame it on the drink, but Shining said he knew something had always been there... He'd been ignoring it, ignoring it the whole time and hoping that it would go away! That her love would go away, her attraction to him! Why would he want that, want her to stop loving him when he was so damn perfect?!

Twilight suddenly wished she had in fact had a whole lot more to drink. She thought back to her night at the bar, Moondancer and Minuette chatting up various stallions, her sipping on her cocktail, and the whole time, her thoughts were on Shining. It was rare that they ever settled on anypony else. Maybe there was something wrong with her, maybe she concerned herself too little with ethics and too much with her heart's desires, but she didn't care. In her eyes, what could ever be wrong about wanting to be with the pony that you cared about the most?

But Shining would never see it like that. He'd made that clear, so obvious that Twilight was beginning to consider the notion that she'd never have another chance with him, no matter what she did. And that was a scary thought to have indeed.

If only she hadn't done it so suddenly, if only she'd bid her time and won him over in a more clever fashion, none of this might have happened! Not only that, but she'd positively mortified herself just now, she'd be surprised if he ever saw her in the same way again. His cute, adorable little sister. His debauched sex pest of a sister that couldn't take no for an answer.

It made her feel pathetic. If only there was a way to make him forget, to make this whole night go away...

Twilight blinked. She looked up and around her, as if the preordained answer to all of her problems had a source, for it had quite literally smacked her in the face right there and then. She could make this night go away. She was a powerful unicorn. With strong enough magic, she could make him forget it ever happened! And then everything would be back to normal, and Twilight could go on with her fantasies, and Shining would be none the wiser!

And then, another thought occurred to Twilight. It was a thought that might not have ever came to her in any other circumstance, if things hadn't gone the way they did, and if she didn't feel as hopeless as she did at present, but it occurred all the same. Despite the ludicrous nature of it, how devious it sounded in her head, she couldn't help but feel a very real smile cross her lips as she realised something else.

With the right level of magic, she could make Shining forget they were ever related.

She'd read about amnesia spells before. She'd never cast one, but she knew all of the appropriate theory, and might have even had books detailing the incantation in her house. Quickly, frantically, she set about finding the necessary materials, reading in a fervour as she looked for the precise information she needed.

And in one compendium of spells, she found what she was looking for. The spell advised use only by experienced unicorns, as it could potentially damage the subject's memory if sustained for too long, but Twilight was a prodigy. She knew how to cast magic as a child that most adult unicorns could never dream of. This would be simple for her.

A gleeful grin crossed her face as she read on, slowly, methodically, being sure to absorb every scrap of information the text could offer. A spell of this calibre would wipe the subject's memories of their past, but it would only work for a single day, unless it was manually renewed by the caster. When broken, the subject would retain all memories of what transpired while they were under amnesia's influence, to the smallest detail.

It was that caveat that made it a gamble. If Twilight did this, she'd have to make sure that whatever she did with Shining, she made him like it so much that he wouldn't be angry by the time he remembered, else she'd only have to try and tinker with his memories again.

But no, she didn't want to do that. If this was her one big chance at getting a shot with Shining, of showing him just how much he was missing out on, then she wanted him to remember, she wanted him to know. If he truly wasn't attracted to her, he'd reject her even as a mare that wasn't his sister, but if he was? Twilight couldn't even begin to imagine what would happen if he was...

She had to plan. She had to make sure she knew this spell to the letter, and then find a way to implement it that would both look legitimate to Shining when he woke up, and keep both him and her away from ponies that could identify her. Not only that, but she'd need to come up with a story, someone for her to be that wasn't his sister, someone for him to be that would keep them away from their friends, parents, colleagues.

It would be a lot of work, Twilight was sure, but in the end it would all be worth it if only to spend a single day with her brother as something other than the innocent little sister, as a grown mare that could seduce and fuck him all he liked and make him enjoy every last moment of it.

And he would enjoy it, Twilight was certain of that. She carried on into the night, ignoring sleep, too focussed on her grand plans for what tomorrow would hold.
