You ask if during the times that she is edging you, what happens if you cum.
"Ah, that's all part of my plan for you, dear: we are still playing our variation, so I want you to really want it and to get as frustrated as possible. So I want you to remember that you can still earn a bead if I don't stop you in time while I am edging you. In other words, you should go for it, and try as hard as you can to have an orgasm."
Great you think, that will be frustrating.
"And I will be doing all of your edging for you, just so I can feel your frustration build better, OK?"
In for a penny, in for a pound, you say, agreeing.
