Cum on Wifes Mouth

I want to ejaculate in my wife's mouth, but she doesn't want me to. How can I persuade her to let me? How many years have you and your been together? How was she when you weren't married? You could start by not telling her you are about to cum while she is blowing you that way once you start shooting it might just go down.You could start cumming on her face and when she complains tell her the facials will stop once you start imbibe what my cock puts in your mouth. Or, look for a mouth that is eager for your seed
