Ballerina desires

You’re a boy and you were mailed by an anonymous person a box containing a set of fancy headphones with a note attached to them saying “I know you’re having difficulties sleeping so these should help”, you then head to sleep that night and you began to have struggles going to sleep so you tried to use the headphones the person gave you and they worked. You continue to use them each night but what you didn’t know is that these headphones have been putting thoughts on your head, thoughts about being more feminine and dancing like a ballerina. Soon enough you change your gender and became a full blown ballerina.
