This is just a late night brain fart of mine but I'd like to see if there's any interest in this.
So brief idea is, a college class are doing a project somewhere in the Amazon ( or any jungle really) and their tour plane crashes. One student, a rather shy and quite nerdy girl gets separated and spends a few days wandering around trying to find the class, who have either been rescued already or otherwise. So this girl is on her own and is found by a tribe of native women, all much taller and stronger than she is. Instead of immedietly killing the intruder they could be curious and of course this idea wouldn't be here if there was no room for some smut and or romance in there.
Perhaps the tribe thinks this girl is a runt that needs looking after, becoming the village 'pet'. Or they could hand her over to the tribe's leader as a gift. PM Me please to discuss, don't post here.
