Husband finished in my mouth without warning

Feel a bit violated tbh. We’ve had a long stretch with no intimacy and we’re not feeling that close to each other but after a few drinks on holiday we started getting frisky. I went down on him and he finished in my mouth without any notice. I hadn’t agreed to that, I really wanted to have proper sex to try and get closer to him. He did bring me to O afterwards but I just feel a bit gross and turned off.
