The succubus wakes you up in the middle of the night, she tells you not to worry about who she is, but who she can be for you. She transforms into various people you find attractive. Firstly she tries to seduce you as your neighbour, then your teacher. She then transforms into your bully who gives you a blow job before finally transforming into the personal trainer from the gym, she strips and you fuck her in multiple positions until there is nothing left for the shapeshifter to feed on, she leaves to find a new victim.
