Under the Hill

It is unheard of for an omega of Bilbo's age to be living unmated, unmarried and alone. It is even more unheard of for an omega to go off adventuring with a hoard of dwarves, but that's exactly what Bilbo does. This will be slash and most likely MPREG later on, please be aware before reading. Bilbo/Nori. Bilbo/Bofur. Bilbo/Dwalin. Bilbo/Fili.
