I guess this should help you.
class A
{
ISet<B> X;
}
class B
{
ISet<A> Y;
}
A.hbm.xml
<set name="X" table="XXX" generic="true" where="if you have any not null
checks here, go for it." inverse="true or false" lazy="true">
<key column="B_ID"/>
<many-to-many class="B, DLL" column="B_ID" not-found="ignore"/>
</set>
B.hbm.xml
<set name="Y" table="YYY" generic="true" where="if you have any not null
checks here, go for it." inverse="true or false" lazy="true">
<key column="A_ID" />
<many-to-many class="A, DLL" column="A_ID" not-found="ignore" />
</set>
Also refer these manuals.

https://www.hibernate.org/hib_docs/nhibernate/1.2/reference/en/html/mapping.html
For a many to many association where items can be duplicates, you should be
using a *bag* on both mapping files. A bag is unordered and unindexed, where
as a set is unique.
I would also strongly suggest www.summerofnhibernate.com
