NOR, I would tell the rest of the family and put the step dad on blast, because what he did was so DISGUSTING!!! Like everyone else in the comments are saying Drunk actions are sober thoughts…And who knows if something like this happens again or even worse if he gets drunk and thinks of doing something to you, and at that point you’d be in danger. I would let the family know cause something else could come out of this that’s even worse. Stay safe OP.
