A Lubbock grand jury indicted Albert Padilla for indecency with a child on Tuesday.
He is accused of performing a sexual act in front of his wife's grandchildren, who are both under the age of six.
According to the arrest warrant, the grandmother walked in on Padilla in the boys' room while they were sleeping.
The report says she caught him wearing no clothes, but he told her, "It's not what you think."
