Adding a stronger twist of dominance is the old “use the married name” thing. So I address her as “Mrs Kay”. So that is a stronger frame in that it implies in a direct sense that she has marital duties to perform. Yet it’s formal enough that it can be used at family gatherings for exactly the same purpose.
The deep kiss routine followed by extended hand as a compliance test. Basically you just hold your hand out to her until she takes it. Then you lead her to the bedroom.
Just text her a booty call. Even sitting in the same room it’s funny.
Go over confidently goofy. “11 o’clock is the make sexy time. Very nice!”
If she walks in front of you lightly spank her butt.
“Cum to bed baby.” (Think Austin Powers inflection here)
Tell her to go put something on from the lingerie department.
Just announce the way sex is going to happen. “Here’s my plan. First I’m going to finger fuck you to an orgasm, then you’re going to be reverse cowgirl on me for about five minutes, then I’m putting you on your back and finishing on top hard and rough”.
