Hi rhiannon, I'm Mitch. I would love to help you write a story. I've been here since 2002, and have written many stories on the forum, as well as taken requests for stories from others.
I left you a message in your pm box, so please check it when you get a chance, and we can discuss what kind of story you want to do. Take care, and I hope to hear from you soon.
All the best,
Mitch
P'S Your idea for a story sounds fine. In fact, it is one of my specialities. I left you another message in your box explaining all about it. Take care, hope to hear from you again soon.
