Sub's First Journey

Good grammar and spelling, but your story has some structural issues. You mix 1st and 2nd person point-of-view, which is confusing. I recommend using 1st person since it is more natural. Also, more dialogue would help - it is more interesting to hear what people say than be told what they said.

I agree with visioneer. However, aside from the structure and POV, I like the insight into your mind and all the feelings that you have during the first encounter. Especially the thoughts of humiliation vs the drive to want to pleasure your Sir. I would be curious if in your next piece if you would delve into what Sir is actually thinking against the speculation expressed at the end ("I realize that while my submission and willingness to submit to you in this way gets you off, that each filthy thing that I do decreases me in your eyes and that you are disgusted by me no matter how much sexual pleasure it gives you.")
