Also, I don't really see her sessions a massage .. it's more like a game. The goal being, "can I last for the entire session?".
I think it's kinda like a game for her as well. She wants to get you as close to the edge, without making you finish. So it's on you to say the safe word before it's too late. It's really intense, but in the end, the release is worth the wait.
Just know... the game is over once you go, so you control your destiny haha
