Addiction Story

Hey I was wondering if anyone had this story idea:

Normal girl gets transformed into a futanari buy a strange drug given to her by a mysterious woman, her dick is 5inches, she masturbates with it and then swears it off. The problem is that the drug is causing her to become addicted to the orgasms and making cum. She's compelled to make cum and to have daily orgasms, as she continues her dick becomes more accustom to her body and begins to grow with every few releases and her cum output is larger everytime. If she goes too long without cumming she starts to experience withdrawal symptoms like fidgeting, cold sweats, and her cock becomes rock hard on a constant basis. She tries to find a cure before her dick completely takes over her life.

Anyone?
