It is a decent story -- not really my fetish, but still enjoyable. Your Queen's English comes through loud and strong, which is fine as long as you realize you are writing for a primarily American audience. You could use an editor to help you, but as long as your happy with the results, you could bypass this (as it seems your intent in this story was, after all, to be crude and effective).
I'm going to read yours right now. I just got my first story approved as well but can't find where it was reviewed......see, I am new to this! Can you tell me where I could find my review?
