A group of women claim they have "hybrid alien children" who live on spaceships.
Bridget Nielson and Aluna Verse from Arizona, USA, believe the aliens abducted them and their children now live on a space craft with their fathers.
However they have no regrets because the sex was the "best they've ever had".
Bridget, 27, described being on the spaceship.
According to Metro, she said: "It was great. It was an incredible super primal, super raw, super primal sexual experience. There was a real freedom and we were really going for it. It was the best sex I ever had."
