But her teenage son had barged into the bedroom and dragged the intruder, who is more than double his age, off his mother while his two sisters called 911, according to the police report.
When officers arrived they found the teenage sisters outside, who told them their brother was in the home fighting off the intruder.
Police found the 15-year-old with his hands still around the suspect's neck, KWKT reported.
Morris, who lives locally but has no previous connection to the victim or her family, was arrested at the property.
He was taken to McLennan County Jail, charged with a first-degree felony charge of burglary of a habitation with intent to commit sexual assault.
He does not appear to have any previous criminal convictions.
Robinson Police Chief Phillip Prasifka told the Tribune-Herald: 'She [the victim] said that Morris threatened her by telling her that he had someone watching her children and that they would kill them,' Prasifka said.
"[The woman] stated that she was afraid to fight back because she was afraid that her children would be harmed."
