Hello, This Question Is Not About Me But About A

hello, this question is not about me but about a family relative. She is 19 and was messing around with her boyfriend, but they did not have sex. However, he ejaculated on her breasts and somehow the semen trickled down her outer thighs and stomach. Does she have a possibility of getting pregnant? She is sure that the semen didnt end up on her vagina, but she is not too sure. Thank you and i await your response.
