Most of the stories I enjoy most as a reader are from the victim’s POV. I write a lot from the perpetrator’s because it’s easier for me, but the victim’s POV is very powerful when done well. Oh, and first person is always stronger, to me, if you can stomach being in the character’s head.
Shadow, I trimmed a couple of your tags and added bondage for the gag and the cage. If you plan this to be an ongoing project you can add tags as you go, and I’ll pay attention and point out any I think you might have missed. Cheers.
