Bloemfontein - "Then my dad and mom pray to the devil and their eyes go black," a slim 13-year-old girl from Bloemfontein said via CCTV, as she testified against her parents in the Free State High Court. While she testified that several men had raped her "one after the other", her father, 44, and mother, 36, sat next to one another in the dock, their eyes glued to the TV, Netwerk24 reported.The father wiped over his eyes a few times, as though he had become teary."My mother laughed at me. I don’t know why," she testified, claiming that her mother had been present throughout the assaults."If I asked her to help me, she said I was a bitch. I deserve it," the tearful teen said.Responding to a question from Advocate Ena Liebenberg, for the State, she responded: "My dad knew; He took videos."At first, they stayed in a "brick house" in Bloemfontein. She couldn't remember how many "men" had raped her there, "but there were several".It happened in her parents' bedroom. "If I didn’t want to pull down my panties, then my mom would hit me. The men said if I didn't want to, they would kill me.""They first had sex with my mother. I had to watch. If I looked away, they hit me."'There were demons'"Then they raped me, one after the other.""I tried pushing them away, but couldn't," the slender girl testified.Asked about her parents' satanic activities, she said: "Dad and mom were not Christians. They worshipped the devil.""They made circles on the ground and prayed inside them. They spoke in strange languages. There were demons."Then they would hit her and her brother."They hit me and my brother several times. I sometimes jumped in to try to help him, but they were too strong."Testifying about their home on a Bloemspruit smallholding outside Bloemfontein, she said the house had always been neat and clean while her grandparents had still been living there. She and her grandmother had seen to it.After her grandparents moved away, she couldn't keep it up with the cleaning."My mother did nothing to tidy it up. She sometimes did washing. For the rest, we had to wear dirty clothes."Plead not guiltyAsked about the fact that neither she nor her brother had attended school, she answered that her "mom and dad said there wasn't money for school [fees]. They used it for drugs and liquor".
