sounds like you have a wonderful evening planned Sir. i expect i may be late with this answer being that this IS the weekend before Valentine's day but might i suggest that you take a collar and leash with you and begin her training in that room, this weekend. teach her how you like to be pleased, tell her how you would like her to address you. if you are serious about moving your relationship forward in this way, you could discuss limits and contracts and safe words. you don't have to have it finalized this weekend and can most certainly use the weekend for a fun 'see what we're getting into' session but if you are serious, you will need to lay the ground rules before you progress too far.
have fun
i hope you will come back and tell us all about it
