Clearly, Orange-kun and Sayoko adopted Anya (or Orange is having pedo time with her, your call-- she was MARRIANNE-SAMA'S vessel after all) and started an orange farm. There, Lelouch and C.C. would travel around selling the oranges, but being the Demon Emperor Lelouch - and more importantly, being "dead", Lelouch must never be fabulous again in order to keep his identity safe.
Alternatively, he died and/or inherited his mother's Geass and is now a ghost chilling with C.C. while she talks to herself.

Or he's just plain dead.
