You, and your girlfriend were at a convention in town as she was excited to be there because the town convention was where you all could get plushies, see cosplayers, and a bunch of other stuff to bring out your inner nerd. Little did you know, was that the Succubus Lust was at the same convention you were at.
While at the convention, Lust was doing a little shopping as she had a bunch of dildos, butt onaholes, tickling sticks, rubber fists, perverted outfits chastity belts, whips, and last but not least porn magazines that would turn her victims on. The only way Lust could afford all of the items she bought, was with the stolen credit card she took from her younger sister Greed. Of course after buying everything she had in her cart, Lust packed everything she purchased in a shrinking bag, unknown that her tail was exposed.
