Christopher Cox, 53, has been jailed after giving a suicidal, homeless woman accommodation in return for sexual favours involving bondage and domination.
He told her to wear bikinis in the house and sleep in his bed each night, Guildford Crown Court was told.
Cox was snared by ITV researchers for The Kyle Files, who came across adverts he had posted. They read: “Are you a young girl aged 16 plus who is stuck at home and wants to get away? Maybe you are homeless and can’t see a safe way out? I have a free room to live in for a young girl aged 14-28.”
