Blow job advice for beginners😂

madison
I've never given a blow job so I have some questions. When he starts to come but I don't want him to come in my mouth then what do I do with his dick?? Does the come shoot out or does it slowly go out?? And if I let him come in my mouth do I just swallow it? I'm so confused and I probably sound so dumb! I need help😂 and any tips??
