with sites like manyvids or onlyfans, lots of amateurs will make custom vids for you for a (usually) reasonable fee! all you have to do is tell them what kinds of things you want them to say or do, they usually have a set of rules for things they won't do, then you just wait a few days and get your video. many of them who have partners would gladly shoot a facial video and then talk about the cum as you said with it still on their face and as they play with and taste it
