I wouldn't worry too much, its actually really hard to get a women pregnant, very unlikely from first fuck, they need to be at a certain point of their monthly cycle etc
I used to worry about this all the time when I was young, now older with 2 kids trust me it took many pumps, not impossible but unlikely. Also condoms have lube on them which kills your swimmers.
The Orientals are very careful when it comes to STD's as well, I think you will be fine, but get a test, enjoy Christmas
