Do you think that was what happens with the Virgin Mary? Pregnancy is possible but extremely (and I do mean EXTREMELY) unlikely.
No.
There's no way the girl will get pregnant, because the boy did not ejaculate, so that means no sperm or semen excreted that will fertilize a mature egg of the female.
The only way that would be possible is if the sperm entered into the vagina. If the underwear was moved away from the vagina at anytime that the boy ejaculated or after and the sperm entered, than yea, it is possible. If there is absolutely no way that the sperm entered the vagina, then the answer would be no. Your call, we were not there.
A boy does not need to wear a girl's underwear if his crouch is getting big because the underwear is not designed for them.
Yes.A girl can even get pregnant if the boy does pull out.
If a boy just hugs a girl tightly, no. She will not be pregnant.
oh girl do it hard on him. and be a little careful but hump it.oh girl do it hard on him. and be a little careful but hump it.
He wants to hump her
Yes sure, no reason why not.
No
I'm not completely sure of your explanation of the boys underwear. Was his penis inside the underwear? Or was his penis out through the opening? If a boy has his penis popped out thru the fly in his underwear, and his penis is in the area of, or in her vagina and he has an orgasm or he has the pre ejaculate fluid that comes in contact with her vagina. Yes, she could get pregnant. If he has his penis inside his underwear up against her vaginal area she might or might not get any sperm close enough to get her pregnant. Unless they have started making underwear for him out of latex (like in a condom!!) cotton has never been considered a good method of birth control.
if she is a virgin then no but she can get pregnant
