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
“Fill me with your cum” or “give it to me” usually make me come instantly after some fucking.
Your partner may reconsider her choice of words. It may even be hotter for her if she realises how easily she can make you cum.
Have fun, both of you ;)
