Looking for an old erotic story

Looking for an old erotic story I saw on asstr.org. A man kidnaps three teens, 2 females one male, and turns them into his sex slaves. He feeds them breakfast every morning since it has their birth control, but they may skip other meals. He has a party where he brings one of the girls and the male out, and makes them both have sex with men. Male sex slave freaks out and tries to kill master. The other girl he keeps for himself and makes her make videos during the day of her masturbating.
