Help please looking for an old Fictionmania Story

Hi to everyone. i hope someone can help me. I've been looking for a story in which the main character is a shapeshifter with special powers who turns himself into a sexy woman, and teleports himself/herself into another universe searching to satisfy his/her curiosity about being dominated, and asks Master Phoenix (which is the only character name I remember) to teach him/her how to be a slave.

Please if anyone can tell me where i can find this story I will be very gratefull.
