I don't put up with much from my boyfriend (other than smelly feet, piles of mountain dew cans, and a few vehicles in the yard ;) I want to please him. If I didn't want to do something then I wouldn't.
It's impossible to know how your girlfriend feels about you cumming in her mouth without asking her. So ask her :)
Think about how you enjoy pleasing her - and then you will see that she, too, enjoys pleasing you.
