Drop her ass and move on.
Game playing is not cool and if someone wants to serve you they will be there when they're supposed to.
Mmmm and this also works the other way - doms can be equally as guilty of this kind of game playing and if a dom expects total and utter submission from his sub he must fulfil his part of the bargain and be there for her too.
Anyone can see.....
Baby you and me,
Got a groovy kind of love.
