No the chance is nearly zero to non existent.you simply cannot get pregnant that way.0.001 posibility comes when you insert penis with precum and she's on the best date and peak of her arrousal.
YOu never know, Im sure he has no garantee of, was that 100% precum or cum , Also was there cum on his finger tips when it went inn . God knows what these ppl do when they are soo greedy on this

. So better to accept the fact that " HE IS GONNA BE A FATHER 
" . If he is lucky the other side will happen .
