It was the meaning that both guys would cum on her face for a good facial shoot. But 1 guy screws it up, he doesnt cum on her face but shoots his first squirt on the other guy his dick. You can see he is not familiar with that cause he makes a scary reaction. It this case its all about improvising and thats what the girl does very good, she licks the sperm from 1 guy from the other guy his dick.
