Well, I can only say she won't break up with you. It depends on how you react after that.
I have also been through this. but the reaction differs with different girls leh..
The sweetest one I had was...
I pump and pump and shoot in. She was also moaning softly in ecstacy. Then
I: Dear, I shoot in leh..
She: huh?? (in a soft tone, then pout her lips and wanting to cry).
I: (hugging her and rubbing our nose together) I will be responsible if you are pregnant ok? I love you.
She: (pouting her lips and in a crying tonee) I love dear dear too..
The worst reaction I had with another girl was..
I: Wah, shiok.
She: Wah lau eh! Y you shoot in?! I thought I told you don't shoot in! (stood up from doggie position, opened the door and slammed behind her and stormed into the bathroom)
I: (Stare blankly) Oi, y that reaction? Safe period mah..
She: (Come back) Sorry. Later Leslie (her bf) would be fucking me mah. If still got your sperm in me and he see it, how to explain?!
I: O. (held her hand go bathroom) I wash for you lor. Don't be angry. (then peck her cheek) (In the bathroom, 'dig' out my sperm with my cock in her again) Shiok hor?
She: Sigh, y isn't Leslie as fun as you? Y did you appear so late in my life?
