Extending the Magic of Dominance

Greetings everyone, I’m fairly new to this community and have a query about being dominant. I’ve recently connected with a woman who shares a casual sexual/BDSM dynamic with me. The challenge I face is finding ways to extend our “play sessions” beyond the standard intercourse routine. To my mind, simply binding her for sex lacks much of the core value of BDSM. My aim is to have scenes where she serves as my slave for several hours at once, so essentially, I’m looking for advice, tips, and suggestions on tasks, punishments, etc., that can sustain the scene’s energy after the initial urge has passed.

thank you
