I'm very interested in your project and understand the protagonist age range well. I have a BA in English Literature, and I have written several erotic stories for other projects.
I'd approach this story from a unique angle, giving the characters depth with an interesting plot. This would not be you typical college romp, coed fucks a professor, or that sort of cliche.
When I finish an initial draft, I send it to you in PDF for review. If you like the product and release payment, then I send the story in a word file.
Please contact me to discuss further details.
