amazon story + orphanage. 
boy is adopted and lives at a seeming normal remote village, except there are no other guys. maybe that's just some kind of coincidence? 
his new mother just happens to be sexually permissive. 
weirdly enough, so is everyone else. 
the town is technically under amazon rule. 
any guys that live there or visit soon get sent to the amazon tribe. 
so the women in town try to have some fun with newcomers while they can. especially the teens who tend to have a particularly strong interest in guys. 
Amazons are unable to conceive men, so they must seek outsiders.

the story is revealed as layers. 
it's a weird sister. 
it's a weird family. 
it's a weird town. 
it's an amazon town. 
it's a repeating routine. 
the orphanage is in on it.
