I had my doubts when I first started this, but before I knew it, I was at the end.
Perhaps the idea of men as sex slaves compelled me on, perhaps it was that it was just different. Either way, the only thing left when I finished, was a longing for more.
Our hero was there for how long, that wasn't mentioned. One question I thought about, was did he perform to complete expectations.
As for the axe wielding girl friend, I found her delightful in how she played her part.
I'd like to give this a five (as the story line was beautiful), but it was really short and a bit lacking in detail.
You mentioned that you had thought to add or change it. Personally, leave this alone. Write another, expanded version.
