Heat by Ragabash

Sweating heavily, Shining Armor stared at the purple filly in front of him. He always thought that making a fool out of herself in front of his crush Cadence was the worst thing that could possibly happen to him. But now, he knew that there was something even worse, because it was happening right now.

“So, can we do it?” Twilight Sparkle asked, looking up at him with an inappropriately cute expression.

The worst thing was that he couldn't even just say “no”, even though that's what he should do. She really seemed to need it, although he didn't understand why. In the first place, she is pretty young for masturbation, so why was it not enough for her? Well, he was aware what was wrong with her, but did it really start so early? And did it really make fillies so insatiable?

He remembered a stallion-to-stallion conversation his father roped him in recently, where he complained how utterly exhaustive Twilight Velvet is during her heat and how it left him nearly impotent for a week afterward. Shining cringed. That was a horrible evening, he learned more about his parents' sex life than he ever wanted. That is, anything at all.

“Well...” he finally said, as if he were ready to finally answer. In truth, he still wasn't sure what to say. “You know... Um...”

“Yes?” Despite know well enough what she asked him, she seemed to be oblivious how wrong it was to ask her brother of all people. She just sat there, waiting for his answer and... Oh, sweet Celestia, was that a puddle between her hindlegs?

“You know...” Shining began again. “See.. No. No, we can't do that.” Seeing her disappointed expression, he added: “We are brother and sister and siblings don't do that. They don't even want to do that with each other.” Or shouldn't at least.

“But I want to have sex with you!” The matter-of-fact way nearly startled him. “And you apparently too.” She pointed with one hoof between his legs.

“Itsjustareflex!” the stallion burst out, putting his front hooves in front of a rather hard part of his body. “Look, we really can't do that. It's wrong to do that with a sibling. Our age difference makes it even worse.”

Twilight thought about it for a moment. “So... Can I ask someone else, then? Like, a colt of my age?”

“No!” Shining said, very quickly and certain. “No, absolutely no. It's so no, you shouldn't even think about it. That question might just as well the definition of 'no'.”

“But that really only leaves you.” The filly pouted, quite annoyed with her brother. “Please, my hooves aren't enough and these urges seem to get stronger. I know that it's wrong, but you are the only one who can help me!” She looked at him with something that could be described as “puppy dog eyes”, except even sadder and cuter.

It should be illegal for fillies to be that adorable. Anypony would become weak when they are stared at like that. But Shining Armor knew that he should be steadfast and not let himself incite to do questionable things with his sister.

“...I'll think about it.”

Then again, he wasn't invincible against this expression himself.

“Really? Thanks, Shining!” Even though it wasn't a clear answer, she seemed to fine with it. She gave him a hug and trotted happily away.

The stallion sighed. As much as he should shoot her down, he feared that he wouldn't be able to do so, eventually. Just what did he get himself into…
