Nhibernate Save relation of same entities into other table

Question

I have a S table. It can have some Children. The Children are same type(S).

Table : S(Id,Name)

Table : S_R(Parent_S_Id,Child_S_Id)

Classes are

public class S
{
    public virtual int Id { get; set; }
    public virtual string Name { get; set; }
    public virtual IList<S> Children { get; set; }

    public S()
    {
        this.Children = new List<S>();
    }

    public virtual void AddChildren(S s)
    {
        this.Children.Add(s);
    }
}

public class SMap : ClassMap<S>
{
    public SMap()
    {
        Table("S");

        Id(x => x.Id, "Id").GeneratedBy.Increment();
        Map(x => x.Name, "Name");

        HasManyToMany<S>(x => x.Children)
            .Table("s_r")
            .ParentKeyColumn("S_ID")
            .ChildKeyColumn("CHILD_S_ID")
            .Cascade.All()
            .LazyLoad()
            .Inverse();
    }
}

but it doesn't work. It is not saving relation in relation table. Could anyone have any idea and view. Please share your view and suggestion.

remove the Inverse() from the HasManyToMany because it tells NHibernate that the other side should maintain the association entries, but there is no other side.
