Sounds like living a dream! I would love to try this (but can't). I have so many questions, I'll start with some "obvious" ones:
1. How did you meet each other (and got to think you'd be a good slave for him/her, he/she would be a good dom/me)?
2. What was the best part of it?
3. What was the harshest part of it?
4. What was the kink you liked the most?
5. Did your dom/me punish you? If so, how?
I'll stop for now
