Tell me what you like, what you want a story to be written about. Give me whatever details you want, and I promise you will the get the first draft and if you want I will continue sending you the extended versions as I do them. Looking forward to your ideas! If no ideas, I have more than 10 finished products and another four in productions, if you’re looking on reading some, I might be willing. Have a sexy day!
