Parent doesn't have collection of children but each child has reference to parent. Is there any way to apply cascade deletion for parent (i.e. when I remove parent all children which reference this parent need to be deleted)?

Is there any way of deleting children of particular parent not even selecting them to domain? I just have parent without children collection and I want to delete parent and its children. I can define children collection (but won't use it anyway) for this purpose but I also have to eagerly load them to allow cascade deleting ((( This is the thing I don't want to do
