If she doesn't mind performing oral, she could perform oral on you first until you have your orgasm. Then, you perform oral on her as you recover. When you can get an erection again, if she hasn't had her orgasm yet, you can then try intercourse again.

You'll get her closer by performing oral on her and you'll probably be able to last longer since it'll be your second time in the same session.

Have fun and good luck!
