How to be a good sub?

[bongacams]

I need a crash course in how to be a good sub! I am totally new to this and have "0" experience with the Dom/Sub culture. I was approached today by this super awesome person who dropped a ton of $$ on me to just kneel for him for a very short time. He was EXTREMELY pleased with my performance and is asking for a longer session tomorrow. I really enjoyed it Smiley Anyone have a good advice? Warnings? Suggestions? Thanks to all you lovely people for your time!
