Frustrated and bitter, young Twilight struggles to improve her powers and become more than a mere stock clerk at the local magical bookshop...if only she could get the chance, she'd show them all!

Fortunately (or unfortunately) she catches the eye of a certain Succubus, who generously decides to help her out with a very intimate spell, and soon, Twilight finds herself being able to create feats of magic she'd never dreamed of before!

Unknown to her, this...spell...came with a...sexy price, and must be restored at least a few times a week by the consumption of a "special" substance...

...only from males!

Story takes place in an Alternate Equestria and is loosely based on the hentai manga Low Level Mage Corrupted by a Lewd Crest.
