Stupid Sexy Flurry

Twilight Sparkle had a problem. That was nothing new. She had had a lot of problems throughout her life. But this one... this problem was different.

This problem wasn't some villain trying to take over or destroy Equestria. She could have dealt with that just fine.

No, her problem was her niece. Flurry Heart had been an adorable and precocious little baby. Ever since she was born Twilight had been overjoyed at the privilege of being her aunt. All that was good. What was bad was that Flurry wasn't a filly anymore. Flurry had done some growing up over the years. A lot of growing up. Flurry was a mare now. A mare that Twilight wanted to fuck.

Twilight was disgusted and horrified at how she felt about her niece. It crossed so many lines she didn't even know how to count them.

And yet... Twilight had never been much of a romantic. She had never had any really strong feelings for another pony, even after she broke out of her seclusion. She had never had any real preference between mares and stallions. Somehow there had never been anypony she had so much as had a crush on. She had wondered sometimes if she just wasn't really attracted to anypony at all.

Until now.

And it was just her luck that now that there was somepony who quickened her pulse, who made her stomach flutter, who made her loins ache with desire, it was one of the worst ponies it could possibly be. But there it was. Her niece was a damn sexy mare, no matter how much she despised that she felt that way.

Twilight didn't want to be a bad pony, but it seemed that, deep down, she was.

The worst part was that she couldn't even talk to anypony about it. Not her friends, especially not her family, nopony.

She kept hoping this sickness would pass. That she would come to her senses, and not have to go around with a barely restrained lust for one of her family members.

Every time she saw Flurry she felt like she was going to go insane. Unfortunately, she was good enough at keeping up the facade that Flurry didn't seem to realize anything was off. Flurry didn't know better: Flurry liked her aunt. Her pathetic, pervert of an aunt.

Flurry Heart had enrolled at the school of friendship. Every day was hell for Twilight. She limited her interactions with her as much as she could. She'd just mumbled something about favoritism as an excuse. Flurry had been disappointed, but understanding.

Why did she have to be so good at friendship! Why was every aspect of her so perfectly tailored to Twilight's interests? Her mind and soul were beautiful. She was deep: deeply caring, deeply curious, deeply gracious. She honestly didn't need to be at the school. Twilight had nothing to teach her—nothing good, at least.

She had a body, too. Stars above, her body! There were no ugly alicorns. It just wasn't a thing that happened. Celestia, Luna, Cadance, and Twilight herself were all beautiful ponies. But Flurry had had the blessings of that state since birth, and it showed. There was not a single inch of her lithe, young body that Twilight didn't long to worship and kiss.

These thoughts were how Twilight tormented herself each night. She started after dinner with some general angsting, then moved on to either disgust with herself, or anger. The anger could be directed toward various ponies. Most often herself, but plenty of other targets too. Flurry Heart was another common one. This all was her fault after all. She just had to go around being attractive and related to Twilight. One or the other would have been fine. It wouldn't be ideal to be attracted to any of her students, but at least there was the possibility of waiting that out. Twilight and Flurry were both alicorns, though. They were going to be around each other for a very long time.

Sometimes, she got angry at Cadance. After all, if she could blame Flurry for being sexy, why not go one step further and blame the source? Her sister-in-law was not an easy pony to hate, though; that never lasted long. Celestia was another fun jump of furious logic to make. She'd been around long enough to see tons of changes—and direct them. She could have gotten rid of the incest taboo if she had wanted to, and saved Twilight all this trouble.

Twilight tried her honest best not to let her feelings affect anything. But that was hard.

She lay in her bed, trying to sleep. That took so long these days. So very long. She saw things when she closed her eyes. She saw Flurry: her face, her mane, her flanks... She was determined not to clop to fantasies about her tonight. She did that far too much. Yet all she would have to do was reach her hoof down and—.

She thought about work. That usually helped. There was always so much work to be done. But tonight young Flurry haunted her even here. To say that she had a very active life was the nicest term Twilight could come up with for her. She had apparently been getting herself into trouble. There was a stack of reports from the faculty sitting on Twilight's desk over at the school. Twilight could almost see it, taunting her. She couldn't bring herself to read them. Reading them would mean she would have to do something about them. It would mean she would have to have a meeting with Flurry.

Her mood swung back around to anger. She was being ridiculous. She was a grown mare, the head of the school. She had faced down monsters without blinking. But one little meeting with a barely-adult mare was too much to even think about? It was a good thing nopony who had ever threatened Equestria had thought to make her go in a room with a filly, or she would have been doomed.

She really needed to get over herself. She'd show that filly. She'd call her up and let her know that she wasn't going to get away with misbehaving anymore. She was a future princess, and she needed to start acting like it, and Twilight was going to punish her in whatever ways were necessary to make it happen.

It was late at night, however, and Twilight's mentally rehearsing the admonishment she was going to give her niece soon derailed into imagining other ways the scenario might unfold. Ways that involved more seducing than scolding. Despite her promise—without even noticing she had broken it—Twilight clopped herself to sleep.
