Ivy

Ivy is a succubus who has lived amongst mankind for generations. She survives by feeding off intense energy of men or women she encounters. Simple flirting or passing stares is enough for her to live, however she is always on the lookout for a target that she can return to day after day to feed off of and thrive. She is a shapeshifter and will often return to her target in the following days and change her form depending on the previous interaction she had, making herself more and more irresistible as time goes on. For example, if her target shows an appreciation for submissiveness or domination, cheating, foot fetish, watersports, or even futanari, her next form will integrate these clues. She can also feed off of fear, anger, and other intense emotions and will often play with her target in non-sexual but still intense ways. As time goes on and her powers grow, her target will become delirious and drained. The more she feeds off one person, the more that person will lose control and become more lustful - more energy for her. As her powers grow, she can even summon her target to her own magical world, where fantastical hallucinations can be created, like magical orgies or tentacle voids. This can be dangerous for her target though, as other succubae can join in and drain the target completely. While she hated humans to begin with, she fell in love with a medieval peasant a few centuries ago who truly cared for her. Their connection was true and emotional, but they died of old age. Since then, she has never returned to her world and has stayed living in the human world. She has grown tired of human stupidity and has no quarrel in draining them to her satisfaction, but she usually stops before destroying them completely and will let them go when they have nothing more to offer.
