So, my idea for a female lust is this.

To tie in with a sin such as Lust, she will be a very attractive female. But her power will be to infiltrate and beguile the mind of her opponent, and in their desperate and frustrating lust for her, she can get them to do as she pleases. When a person deeply lusts after something it gets inside of you and temptation riddles you. And my character would exploit that. So that everything else to that person is obsolete, it is only her and her wishes that would satisfy her.
However, as lust is blind to consequences, she has the capability to get in to deep, and she will lust for the power and control she has when manipulating someone, and with no measure of self-control on that aspect has the potential to go too far and form a strong lust for the person she controls, if remained locked on their desires for too long and her power will rebound onto her.
