A 41-year-old woman is facing arrest for allegedly having a sexual relationship with boy that began when he was just 13-years-old.
Karen Lee Carstens volunteered to help babysit the teen while her friend, the boy’s mother, was hospitalized.
Police say the victim said Carstens told him not to tell anyone about their sexual relationship because she could get into trouble.
The affair began when Carstens volunteered to look after the 13-year-old boy while his mother was being treated in a Houston hospital.
The boy told investigators that when the relationship began it involved just touching her breasts and genitals, but progressed to oral sex.

The court documents revealed the concerns of the teen that he would get Carstens pregnant.

He described one encounter where he suggested anal sex as a way for them to avoid pregnancy. She at first refused but then allowed the teen to do it.

The affair ended in 2009 when Carstens moved away from the Houston area.

Carstens, now 41 and living in Riva, Maryland has been charged with sexual assault of a child by authorities in Houston.

She is not in custody but a warrant has been issued for her arrest.
