A young woman has an Uncle who is only a year or 2 older than her. She moves in with him with the intention of it being temporary. They party one day, not knowing there's something "funny" in an item they consumed.They end up sleeping together. Granted, at first they feel weird and guilty. But after some time they try it again. They love it. But the niece loves it more and becomes obsessed with sex with her Uncle. Eventually she's tested and is tempted to have sex with other guys. She ends up pregnant, most likely by her Uncle.
