We had unprotected sex. Then after we finished, 1 hour passed and we had unprotected sex again, but before this second time, she gave me oral sex for 10-15. Could she be pregnant because of the second time? Has the 1 hour period and the oral killed all the sperms from the first time?

First time or second time, she could get pregnant from each, better chance from first.

You will never know if it was first or second time,

My fault, I wasn't clear enough. The first time we had it, after we thought is enough, I "finished" in the bathroom (nowhere near her body). Then after 1 hour we had sex again, but first oral for 10-15 minutes. I'm asking, is there a risk that some sperm was still alive from the first time on my penis (even though it passed 1 hour (they hopefully dried out) and they got in touch with saliva)

Unprotected sex can cause pregnancy whether you "finished" inside her. You will have to wait and see if she gets her period.

Today she finally got her period lol. Love you all and thanks! :*

You dodged the bullet.

For future reference, there is plenty of sperm in pre-ejaculate to get the girl pregnant. You don't need to "finish" inside of her in order for pregnancy to occur. Heck, you could use 3 different forms of birth control and she could still get pregnant. There is no form of birth control, other than abstinence or a complete hysterectomy, that can prevent pregnancy.

So, if you're not ready to be a dad, you're not ready to have sex.

There is plenty of sperm in the early fluids, so finishing in the bath room does not stop pregnancy.
