Hi there!
Please ignore my bid amount. I don't know enough about the project to give you an accurate quote for how much it would cost. I won't waste your time by writings an essay here, but I will give you a few of the important reasons why I would be a great choice for this project:
1) As you will see from my profile, I maintain an incredibly high rating on this website. When I accept a project, I don't stop working until it is exactly what the employer needs.
2) I have a great deal of experience with writing erotic content, both on Freelancer and elsehwere. If you look through my reviews, you will be able to find feedback from such projects. Alternatively, I have personal writings on Literotica, some of which have 12,000+ views and have been favourited hundreds of times.
3) I'm a native UK Englisher speaker/writer, but most of the work I do through Freelancer is in US English, and so I'm fully capable of using whicever you prefer.
If you have any questions, wish to see examples of my work, or simply want to discuss the project further, please don't hesitate to get in touch!
I hope to hear from you!
