This girl and I were hanging out in my car and we talked for some time (a few hours) and then things started to heat up and long story short I started to give her oral and she reached climax and then she gave me oral and I ejaculated and it fell all over my stomach and she accidentally touched it and then she rubbed it around her fingers in an attempt to dry it then minutes later without thinking she rubbed her vagina and then realized what she was doing and stopped is it possible for her to be pregnant and if so how possible? What are the chances?
