Intriguing. I like your writing style, and you have excellent flow. This was truly and enjoyable short story, and I hope you expand on it more in the future!
I loved your story. I agree with everyone else it should be longer. I get writer's block to and what helps me is trying to clear my mind. Going for a walk at night or sex with my master to give me more kinky ideas. Best of luck with your others and look forward to reading more.
