Twilight Sparkle Lost Her Marble

by that decepticon pony

First published

Twilight Sparkle thinks she might be sick right before her second Grand Galloping Gala: her flank hurts, there's pressure down there, and she can't stop thinking about stallions. When her doctor breaks the news that it isn't a urinary tract infection, her reaction is predictable. Can she pull herself out of estrus before the Gala? If not, can she learn to live with it until she can get her IUD replaced?

Be prepared for lots of ship teasing, mostly with characters not selected due to space limitations. And most of the sexy stuff is pretty coy, so don't let the sex label scare you away.
