It’s not often but I hear this occasionally from my partner. She is not in a rush to do something else, she’s just had enough of getting fucked.
She doesn’t seem to realize that the negative feelings of that phrase actually inhibit you from cumming.
A better line would be, “I’m feeling a bit dry. Would you mind releasing your load into me now?”
Now that phrase would trigger a quick finish
If my wife ever said that to me I would stop ask if she was getting sore/dry and that I could just jerk off if she didn’t want to continue. I’d offer to use a toy on her if she still wanted to get off.
