Freaky woman with snake fetish ages guys to keep her youth

[AoTFan]

Okay, so there's this movie with a white dude who travels to some place (India, maybe?) and meets this dark skinned woman.  Turns out she's several hundred years old.  A certain times she'll have sex with a random guy and that guy will end up aging several decades while she maintains her current form.  She's got a thing for snakes, and I think one of them is like a magic snake or something.  Anyway, the guy finds out her secret, but is beholden to her because she's decided to make him her permanent mate.  Meanwhile, guys girlfriend shows up with his pet eagle (or maybe a hawk, not sure), but before it can challenge the snake, it eats some of the poison fruit that grows on a tree at the plantation where the snake woman lives.

Near the end, this old dude (who was one of snake woman's previous victims) bursts into the room with a machete and chops the magic snake up into several pieces.  This causes the woman to disappear (or something, I'm not sure), but each piece of the snake forms a new snake and promptly kill the guy.  

Does this ring any bells with anyone?
