There are so many things you can do to keep it fresh.

Here are some of ours and FYI all require tribute and all expenses paid.
Shopping together - minimum spend $250
Fin Domme time fun - tied up while she shops with my card - $250 minimum
lunches - $60
dinners - $100
Manicure - $0 but expenses paid
Pedicure - same
Movies - out and at my home - $100 per hour
Couples massage - $0
Serving as chauffer - $0
and of course sessions with many extras that if done by her require extra tribute on top of hourly rate. No cum tax since I have not been allowed to since July 2018. Only milkings.

Keeping it real. Oh it is. I belong to her and she is in charge when we meet and what we do. I make suggestions but all decisions are hers. It is pure D/s when we are together.
