Texas authorities have unraveled a sadistic game involving a babysitter who allegedly sexually abused babies and then sent pornographic images of them to her boyfriend. 

Ashley Virginia Dack, 29, was charged last Friday with sexual performance by a child and super aggravated sexual assault of a child after Harris County sheriffs obtained explicit texts and photographs shared with her boyfriend dating back to at least 2012, Click2Houston reported.

The boyfriend, Patrick Schuneman, was also charged in the case.

"The defendant and co-defendant shared text messages over time that suggest something more sadistic than your typical sexual abuse," Prosecutor Stephen Driver told the news site.

The Houston babysitter would allegedly perform sex acts on the children she was charged with caring for and then describe her actions in explicit detail to Schuneman, according to court documents obtained by the news site. Dack also sent Schuneman inappropriate images of children- including one of her molesting an 11-month-old.

One text police say Dack sent her boyfriend in August 2012 reads: "There is a little girl at lunch... Wanted you 2 to be hiding in my car and I could bring her 2 you."

Police were alerted to the alleged abuse when one of Dack's friends, to whom she bragged about her crimes, called the authorities in Oct. 2014.

Dack was ordered held on $350,000 bond.
