Your friends are rapists. Try to talk some sense into them. Tell them how they would react if someone did that to their daughter. (this rewires their dumdum male brains)

I don’t like the daughter scenario, because you should want to do the right thing even if family is  not involved. 

That said, mom or sister would work better because those two people already exist in their lives.
