Guys who just cum without getting your approval first are a-holes. An ex came in my mouth, assuming that’s what I like. He cum was gross and tasted bad, so after he finished squirting, I leaned over and he thought I wanted to kiss him. Instead, I spit the entire load onto his face and got it in his eyes. He never did that to me again.
What did you expect was going to come out of his dick? Apple juice? You should have told him you don’t like cum in your mouth ahead of time, instead of assuming he knew semen absolutely revolts you (which is not a turn-on, btw).
