Hi guys. Thank you for your link to this story. I found it a very well written piece, and I wasn't bothered by the switch in POV - not an issue of tense, I think. I'd certainly look forward to more stories from you both.
BUT, and, for me, this is a very big BUT - I didn't like it

Now obviously, I can't just leave it there. I felt that the story moved too far too fast. Now, anyone who has read my stories would feel inclined to scream, "hypocrite" at the top of their voices. However, while we know that Lily wanted "some form of control", you have her filled up with booze and raped in a back alley by two low-lifes, all within a few hours of meeting Martin. I'm not saying this is impossible, just that it is "a bridge too far".
And she wakes next morning to find that her pussy lips have been pierced and locked with a padlock that says "Property of Martin" but that she was too drunk to know or care about what happened. IMHO, this comes perilously close to the Literotica ban on stories about rape; this is usually circumvented by ensuring that the one who has been raped discovers some pleasure or positive feelings from the experience. I couldn't find this in your story.
Perhaps this story is about 500 words too short. What are Lily's feelings when she wakes to her discovery? Where is Martin? I suggest this could be improved by rounding out the story and letting us know the outcome, with the sense that lily actually does gain satisfaction and pleasure from her experiences.
Let me say again, I thought the standard of the writing was excellent, and I would never just give it two or three stars because I don't like it. I wouldn't vote on it, not because the writing is substandard (it isn't) but for the simple reason that it doesn't push my buttons. And, of course, I accept that many other readers WILL experience pushed buttons.
thanks for an interesting read; it was worthwhile and I look forward to your next adventure.
