I've read a few of your stories now, by and large the content tends to be a little too extreme for me, but I do quite like your writing style. This story in particular I think managed to keep a good pace and not become too fantastical to not be taken seriously. Though there were a few glaring spelling and grammatical errors I could do without, overall I think I'd like to see more from you. :)
This was quite nice, but next time when a heroine is unshakled she won't be so receptive. No matter how much scared she is
Other then that I really enjoyed this.
Another thing I'd like to mention; most of your stories seem to have Bad Ends (as in the unhappy kind). So, I'd like to cast my vote on an ending for this one; Stargirl escapes and brilliantly murders her captors, or hires Deathstroke to do so, and rather then return to her old life she becomes a Super Villain! This would be a fitting back story to a villain.
Or the Bruce Wayne ending. It'd be interesting to see him react, or a really Bad End... He fails to recognize her as Stargirl.
No matter what you go with I'm sure it'll be worth reading.
I'm not writing specifically about this story but just in general. I've been enjoying your work for about the last five years now. I don't read all of them nor do I manage to fap off on them all the time. What I like depends heavily on the theme and characters used. For me, it's regular guys dominating powerful women like this story here. Regardless, I'm quite impressed with the range of stories you tell and your writing skills but most of all, every one of your stories I've read, you managed to surprise and sicken me(in a good way) with your innovative concepts and descriptive writing on the torture and humiliation scenes.
Hope you're not too discourage from the lack of responses to your stories. It doesn't seem like a very rewarding experience in that regard but I'm sure there are a bunch of other lurkers like me who enjoy reading your stuff. I hope your creative juices keep flowing!
