Twilight Sparkle is a bit of a naughty mare. Ever since the magical circumstances that gave her a penis to put every stallion in Equestria and beyond to shame, her sex drive had heightened. For whatever crazy reason, she agreed to take part in the No Nut November challenge. The first week was fine, the second was the beginning of her pains, the third saw her needing to be locked within her room, and as the fourth week comes to its end, she is not a mare, but a feral beast. Her body needs to breed, and whoever would be unfortunate to come across her path when she is free, may Celestia have mercy on their body.

Disclaimer: No visual sex, but the tab is there as it is heavily mentioned and implied what happened through context clues.

This is part of my 1K Challenge.
